Not everyone has access to the Internet to buy it online, enough money to buy a ready-made one, a vacuum chamber to mold it and buy silicone. My idea is to send the model and the tpu filament for example in fablabs and it would be possible to print it quickly. Anyone can participate in the fablab for example by making a free donation in a box next to the 3D printer, for example. We will therefore be able to apply this principle in developing countries and in all places where there is a person in need. It all started on Thingiverse and with @Totdahl who was able to print the prototype0 and give me feedback on the file. She also posted it on the 3D printing group on Facebook ,which allowed me to get positive as well as negative, disgusted or amused feedback. Unintentionally they all participated in a discussion about the female body and the taboos it still represents today.

- CCD-or CMOS-lab-on-a-chip based on discrete converters of different physical and chemical parameters of samples into the optical signals with positional sensitivity for morphometry of non-optical patterns + (The literature analysis suggestes that a c … The literature analysis suggestes that a complex characterization of physiological activity of a living organism requires dozens or hundreds of chips depending on the task. For example, there are both active and passive chips used in biophysical, molecular metabolomic and genomic studies in fundamental and applied molecular medicine: a. allergology (Taira, 2009; Lupinek, 2014; Seyfarth, 2014; Zienkiewicz, 2014; Williams, 2016); b. haematology and transfusiology (Hassan, 2015; Nguyen, 2015; Chen, 2015; Kuan, 2015; Rafeie, 2016; Mielczarek, 2016), including blood-brain barrier research / modeling (Shao, 2016; Bonakdar, 2016; Brown, 2015; Deosarkar, 2015); c. lymphology (Hanna, 2003; Shimizu, 2007; Moura, 2016) and phlebology (Franco, 2012; Brivo, 2012; Zhou, 2012; Ryu, 2015); d. cardiology (Tanaka, 2007; Chean, 2010; Grosberg, 2011; Agarwal, 203; Wang, 2014; Rismani, 2015; Jastrzebska, 2016; Marsano, 2016; Zhang, 2016); e. gastroenterology-on-a-chip (Yang, 2009; Esh, 2012, 2014), including gut-on-a-chip techniques (Bjerketorp, 2008; Kim, 2008, 2016; Tottey, 2013; Lee, 2016); f. cellular neurophysiology-on-a-chip and neuromorphogenesis-on-a-chip (Millet, 2010; Ling, 2010; Kim, 2014; Huang, 2014; Wei, 2014; Kunze, 2015; Yamada, 2016); g. endocrinology (Marchesini, 2007; Bovet, 2007; Srivastava, 2014); h. immunology (Yakovleva, 2002; Yang, 2005; Corgier, 2007; Liu, 2011; Zhang, 2011; Kayo, 2013; Wang, 2015; Ali, 2016); i. general “splanchnology-on-a-chip” based on N principally equivalent approaches: “organ-on-a-chip” (Wikswo, 2013; Ahmad, 2014; van der Helm, 2016; Mousavi, 2016) / “organ-on-a-chip” (Lee, 2013; Bhise, 2014; Odjik, 2015; Kim, 2015; Caplin, 2015; Sticker, 2015; An, 2015; Zheng, 2016; Cho, 2016), “organoid-on-a-chip” (Skardal, 2016) and “physiome-on-a-chip” (Stokes, 2015), which can be integrated in the frame of concept “body-on-a-chip” (Esh, 2011, 2016; Williamson, 2013; Reif, 2014; Sung, 2014; Kelm, 2014; Ryu, 2015; Perestrelo, 2015); {etc.} The above problem made the study so complicated, that it became quite unfeasible, since the “multi-chip” analysis (see Terminological remark No. 1) turned to be very expensive and the large sample volume required for such a complex analysis could not satisfy the principles of non-destructive diagnostics on a chip (for example, see (Takahashi, 2004; Feng, 2015)) due to many biomaterial sampling points (for example, see (Ando, 1987; Nikolaidis, 2012)) standardized in the protocols for biomedical and veterinary diagnostics. On the other hand, the difference and variety of the sampling and the sample preparation techniques for different microchips and standard diagnostic methods made the problem of analyzing the complex biochemical physiological state of the organism unimplementable and poorly informative. It is quite obvious that for the purpose of compatibility and comparability of the measurement using different analytical devices (see Terminological note No. 2) it is necessary to provide the compatibility and comparability of the sampling and the sample preparation methods. In the ideal case, all the analytical procedures should be performed with a single uniformly calibrated device using the same sample for all the tests without moving the sample from one device to another. To date there are independent calibration methods for chips (Gillot, 2007; Binder, 2008; Karsunke, 2009; Nakamoto, 2010; März, 2010; Song, 2012; Buchegger, 2014), as well as the calibration protocols for other analytical methods (including the imaging ones) using chips (Su, 2016; Garnica-Garza, 2009). Hence, we need an equivalent of cross-calibration in the interpretation close to that given by NIST for cytometry (Hoffman, 2012), although the term was used much earlier in radiology (including tomography) and nuclear medicine (Paans, 1989; Genant, 1994; Tothil, 1995; Grampp, 2000; Geworski, 2002; Hetland, 2009; Garnica-Garza, 2009), as well as in the number of spectroscopic methods applied for the biomaterial analysis (Kwiatkowska, 2008; Wang, 2012; Poto, 2015; Liu, 2016). In addition, when we deal with the structured samples such as biological tissues, it is also important to obtain information on the spatial distribution of the substance or property analyzed in the image form, for example: o magnetic field imaging; o electrochemical parameters and field gradient; o laser beam transmission outside the visible spectral range; o distribution of the emitting regions in autoradiography; o polarization characteristics and the angular fluorescence polarization; o the local temperature of the sample at different points on a chip{etc.} Moving the sample from one microscope to another makes it difficult to establish the correspondence (colocalization) between the regions of interest (ROI) for different wavelength ranges (or different physical characteristics) allowing to perform the mapping and identification of the components under investigation due to the difference of visualization in different spectral ranges (or different physical “descriptors”). This prevents one from combination of the signal distribution maps from different spectral regions, and hence, makes it impossible to establish the correlations between the presence and distribution of the certain components or physical and chemical properties in the sample / tissue. Since different components of the analyte possess a number of colocalized characteristics in different spectral ranges (Zimmermann, 2005; Gavrilovic, 2009), it is possible to perform either a simultaneous or a sequential mapping and identification of several tissue components based on the physically different properties. For example, some target components can be visualized using non-spectral properties, such as magnetic fields (Gruschke, 2012; Kim, 2015; Hejazian, 2015), labeled atom diffusion (for example, see: Parker, 1981; Galbraith, 1981; Blakely, 1986; Hein, 1986; Nemecz, 1988; Pouteau, 2003), temperature maps (Choudhury, 2012; Rosenthal, 2014; Karadimitriou, 2014; Meng, 2015; Lo, 2016) or redox maps (including ratiometric those (Herman, 2005; Hilderbrand, 2008; Zhang, 2015; Chen, 2015; Pan, 2016)) on a chip (Jezierski, 2013; Gashti, 2016). We propose to implement a full range of methods for mapping the biological tissue parameters with or without specific labels using planar transducers / converters of the non-optical signal to the optical one, as will be described below. This will also result in the substitution of a number of independent expensive diagnostic devices with a simple unified complex diagnostic and analytical device. The operator of such a complex lab-on-a-chip will predominantly perform data analysis and processing (a so-called data mining, which is now mainly used not in the active mapping or imaging chips, but in the passive chips for genomic and peptidomic investigations (Lee, 2001; Smith, 2005; Abascal, 2008; Ghanekar, 2008; Usui, 2009; Nussbeck, 2013)) rather than routine analytical procedures (such as sampling and dropping (Fang, 2002; Du, 2005; Cellar, 2005; Huynh, 2006; Zhang, 2007; Do, 2008; Jang, 2009; Kertesz, 2010; Sun, 2010; Coskun, 2010; Wu, 2012)) due to an automatic machinery. This is in consistence with the modern trends in the development of the information society and the extension of the applicability of the chemoinformatic (“chemobioinformatic” (Basak, 2012)) software for biomedical and pharmaceutical (Weinstein, 2001; Shedden, 2003; Shedden, 2004; Parker, 2004; Ghose, 2006; Kong, 2008; Speck-Planche, 2014; Capasso, 2015; Gromova, 2016), agrobiological and biotechnological problems (Speck-Planche, 2012; Grädow, 2014). In this regard, the design of the above proposed complex devices for multi-parametric analysis and mapping of the samples is of great importance for analytical practice both for improving the quality and information content of the analysis and for the rational use of the working time of the analyst. The possibility of connecting such devices to the PC and mobile network resources (Lillehoi, 2013; Wu, 2014; Pan, 2014; Koydemir, 2015; Bhavnani, 2016) allows to improve the quality of telemedicine (Fleck, 1999; Bishara, 2011; Balsam, 2015), GIS – coupled analysis / sample analysis in the field conditions with the geodetic reference (Senbanjo, 2012 Gerald, 2014; Ferguson, 2016), quality control on a chip (Shearstone, 2002; Hartman, 2005; Zhang, 2005; Stokes, 2007; Pierzchalski, 2012) in chemical and biotechnological industry using SCADA and similar systems (Gieling, 1996; Ozdemir, 2006; Smith, 2006; Moya, 2009). The implementation of the technology proposed will increase the labor productivity of the analysts and researchers, since the performance of N analyses with a single device equals to the N-times reduction of the amount of the auxiliary routine work compared to the performance of each analysis with an independent device requiring different sampling procedures and sample treatment protocols. Since the first labs-on-a-chip were developed by the author for his own research problems and were tested in the routine research practice, he could easily appreciate the ergonomics and usability of such devices with the maintenance of the quality and increase in the rapidity of the analysis. '''Novel approach''' The contemporary analysis of the literary and the preliminary calculations, suggested using an optical channel for analytical data acquisition with the CMOS and CCD detectors. However, the serial CMOS and CCD allow detection only the optical parameters providing the analyte concentration measurements by absorbance or transmittance or fluorescence of a selectively bound dye. Modern CMOS- and CCD-based labs-on-a-chip fail to perform visualization of a number of characteristic descriptors for many biological and medical samples, such as magnetic fields, temperature profiles, localization of radioisotope sources and selective emission from cells and tissues in autoradiography, etc. Meanwhile, nothing prevents us from using the primary signal converters of the required parameters / variables into the optical signal. There are known: · magnetooptical converters and indicator films (Anderson, 1968; Harms, 1980; Aulich, 1980; Papp, 1980; Arkhangel’skii , 1986, 1989; Challener, 1987; Mao, 1989; Challener, 1990; Krafft, 2004; Fratello, 2004); · radiation-optical (spectro-)colorimetric converters (Apanasenko, 1981; Kulagin, 1983, 1984, 1985, 1987; Bazylev, 1992; Mikhailov, 1996; Kulagin, 2003, 2006; Kulagin, 2007; Sadulenko, 2009) and thin film scintillators (Albul, 1968; Avdeyev, 2001; Garcia-Murillo, 2003; Berdnikov, 2013; Tolstikhin et, 2014; Inami, 2015; Rincón-López, 2016; Park, 2016); · thermo-optical effect transducers-converters (Malashko, 1974; Dolgov, 1979; Pálfalvi, 2004; Liberts, 2005; Gunyakov, 2006; Nedosekin, 2007; Loiko, 2012), including thermochromic ones (Soloway, 1955; Chivian, 1972; Yang, 1979; Mazumder, 1995; Qazi, 2003; Siegel, 2009; Sia, 2009; Shelton, 2010; Qian, 2012; Heo, 2012; Zhou, 2013; Funasako, 2013; Li, 2013; Bond, 2013; Seeboth, 2014; Kim, 2014; Wan, 2015; Liu, 2016; Zhang, 2016), including infrared-sensitive metamaterials; · chemo-optical active interfaces (van Gent, 1990; Wroblewski, 1997), colorimetric or flouorimetric indicator films (Chen, 1997; Nakamura, 2003; Kowada, 2004; Lü, 2006; Thomas, 2009; Gao, 2011; Kassal, 2014; Mills, 2016; Choi, 2017) and papers (Yeoh, 1996; Ostrovsakaya, 2004; Gaiduk, 2009; Ganesh, 2014); · electroluminescent (Vlasenko, 1966; Shaposhnikov, 1970; Ramazonov, 1972; Samokhvalov, 1993; Brigadnov, 1993; Gurin, 1997; Savikhib, 1997; Zabudskii, 2000; Maltsev, 2011; Rodionov, 2013; Meshkov, 2014; Evsevichev, 2016) and cathode-luminescent indicators / phosphors (Tebrock, 1968; De Mets, 1971; Suzuki, 2009; Obraztsov, 2013; Kaz, 2013; Shi, 2014; Li, 2016) and other position-sensitive target signal converters into the optical signal[1], which allow a direct realization of the “two-level conversion” including a first conversion of the analytical signal into the optical one by the planar converter located above the photosensitive CMOS / CCD detector with the subsequent conversion of the optical signal into the electrical one by the optoelectronic converter (CMOS or CCD). The above converters being placed into the cartridge or cassette system, or the rotating disc (this is a reversible idea from lab-on-a-disc design (Park, 2012; Glass, 2012; Hwang, 2013; Bosco, 2013; Delgado, 2016)) can be replaced by one another in real time allowing to vary the measuring parameters, and hence, providing the sequential mapping and measuring of the above parameters. At the first step the single devices (chips and the corresponding readers) have been developed for the single parameter registration (e.g. a special compact device for magnetic field visualization has been designed using the magnetic film converter (flux detector) and a similar radiographic visualizer has been developed based on the scintillation plates). Later these devices were combined into a single hybrid device with the incomplete set of the primary converters for the purposes of the complex analysis (see Figures 1-3). At the final step we are going to overcome those limitations and to develop a hybrid multi-functional lab-on-a-chip allowing to perform in a single run of the cassette with the cartridges-converters the full position-sensitive mapping of the spatial distribution of the following parameters: I. spectral / colorimetric, densitometric and fluorescent parameters of the analyte for histochemistry and immunofluorescent analysis; II. luminosity distribution beyond the optical spectral range for laser diagnostics or the on-chip LDV, LDA, LDF, laser-accisted PIV; III. magnetic field for selective staining of biological tissues with the magnetic nanoparticles or for the on-chip testing of the pharmaceuticals' targeting in the external field; IV. distribution of the emitting regions in autoradiography and for the sample analysis with the radioactive contamination; V. polarization parameters and the fluorescence polarization for those cases when the rotation of the polarization plane is a diagnostic criterion, from simple saccharimetry to the chirality-based analytical methods introduced from molecular biology; VI. the slide temperature (for the living slices and tissue cultures) for determination of the biothermogenesis intensity or the redox transformation intensity, which is one of the most important diagnostic criteria of the neoplastic processes in biopsy; VII. pH, Eh, pX, etc. using discrete indicator films by the colorimetric, spectrocolorimetric or fluorescence response signal (see Figure 4). The cartridges-converters can be either built into the chip reader (the most suitable configuration for the ultracompact disposable chips without the recording and processing units) or implemented directly into the autonomic chips in the case of the autonomous reusable devices. In the early prototypes developed by the author the chip was combined with the reader forming a so-called self-reading chip capable of the telemetric data translation through a radiofrequency channel (Notchenko, 2012, 2013).frequency channel (Notchenko, 2012, 2013).)

Compatible for MFX and DCC++ decoders. This project comes from another project called ATBS (Arduino Train Blocking System) the problem with this was that it was barely reproductible. I mean that we made 3 zones (3 blocks) and each time we needed to add one zone or one block we needed to change the code and all the hardware and stuff. Also, there was so much wires that it was impossible to troubleshoot. This project has the same goal as ATBS: prevent accidents using a train blocking system (as in IRL) for Märklin trains as well as DCC++ decoders. But STBS is also very easy and fast to build. The principle is that there is one STBS unit by block, and each unit is connected with the next one and the precedent one.

Le projet Polargraph fait partie des projets de DrawBots - c'est à dire, des robots qui dessinent - qui se basent sur des coordonnées polaires. C'est pas très clair ? C'est normal ! Comme une image vaut mille mots, jetez un oeil à cette vidéo : Le principe en avance rapide : 1 -Prenez une grande feuille de papier et scotchez-la sur un mur. 2- Prenez un crayon et posez la mine sur la feuille de papier. 3 - Attachez deux ficelles sur le crayon. 4 -Fixez deux petits moteurs en haut à droite et à gauche de la feuille. 5- Attachez une ficelle à chacun des moteurs 6 - Selon la rotation des moteurs en haut de la feuille, les ficelles qui y sont attachées feront bouger le crayon dans un certain sens et pourront ainsi créer un dessin. 7 - Pour piloter les moteurs et donc les ficelles et donc le crayon qui donne forme au dessin, on utilise une petite carte électronique à laquelle on transfère un dessin créé au préalable sur ordi. 8 - Et voilà, vous avez votre Polargraph ! Capitche ? Rassurez-vous ! On comprend mieux au fur et à mesure. Le Polargraph est un projet que son créateur, Sandy Noble, a initié et documenté son projet depuis 2011. Il partage ses fichiers en Open-Source et en Open-Hardware et actualise ses avancées sur son blog ou sur le site de tutos Instructables. Pour celles et ceux qui, comme moi, n'avaient pas le courage de sourcer tous les composants, Sandy vend également à bon prix les composants de ses Polargraph en kits. C'est ainsi que j'ai fait l'acquisition d'un Polargraph début 2016 en kit. À ce jour, Sandy est à la version 2.0 de son kit et en vend deux modèles : * Le PolargraphSD v2.0, en grande partie pré-assemblé et qui contient quasiment toutes les pièces pour commencer. Il est vendu pour 230 livres (environ 300 €) * Le Polargraph SD vitamin kit qu'il faut monter soi-même et auquel il faut rajouter quelques pièces à acheter ailleurs. C'est ce dernier que j'ai utilisé et dont je vais décrire le montage ici. Il est vendu pour 120 livres soit environ 160 euros auxquels il faut rajouter environ 60 euros soit environ 220 € de budget) À noter que la documentation de ce projet est beaucoup plus complète sur le site ou le compte GitHub de son créateur. Je reprend ici en grande partie ses tutoriels et vous conseille donc de suivre attentivement les discussions plus récentes autour du Polargraph sur la toile (l'occasion de vous mettre à l'anglais ;-)).

- Mood Box, Sons et Lumières/fr + (Vous trouverez dans ce paragraphe le proje … Vous trouverez dans ce paragraphe le projet décrit un peu plus en détail. === Préambule === Ce projet est un projet de groupe (FaB team) réalisé dans le cadre de la formation hybride "Fabrication Numérique", promotion juillet 2018. Ce projet de fin de parcours met en œuvre une partie des savoir-faire acquis au cours de celle-ci et scelle la formation. Il vient donc en complément du projet "bentolux" qui sera bientôt documenté et référencé sur wikifab.org . Les instructions de base étaient les suivantes : * concevoir un nouvel étage sur une boîte existante conçue au fil de la formation (3 étages possibles à disposition : 1 socle, 1 en plexiglas, 1 pour l'écran LCD) ; * utiliser pour ce nouvel étage les connaissances acquises : impression 3D, découpe laser, etc ; * programmer via Arduino au moins une interaction avec l'utilisateur (à nous de choisir cette dernière). === Spécifications générales === Après réflexion, notre groupe a décidé de créer l'étage musical "Mood Box" qui viendrait compléter la station météo déjà prévue avec l'étage socle et l'étage écran LCD. Le comportement prévu est décrit dans les paragraphes ci-dessous. ==== Démarrage de la boîte ==== Une fois le bloc d'alimentation correctement branché, le démarrage de la boîte est réalisé par le biais de l'interrupteur en façade. Ce démarrage déclenche les événements suivants : * la figurine au sommet de la boîte tourne sur son support ; * cette "danse" est agrémentée d'une animation lumineuse via l'anneau de LEDs situé sous le support de la figurine ; * l'écran LCD affiche un message de bienvenue. S'il n'y a aucune autre action dans la foulée, la boîte passe en mode "veille". Dans ce mode, l'écran LCD affiche la température et le taux d'humidité accompagnés d'un message. Ces messages comme la couleur appliquée à l'anneau de Leds et au fond de l'écran LCD dépendent de la température détectée, à savoir : * la couleur (LCD/Led-ring) varie du bleu au rouge proportionnellement à la température ; * le led-ring scintille à une fréquence aléatoire pour donner de l'animation ; * un message variable par tranche est affiché sur l'écran LCD. ==== Activation de la Mood Box et comportement ==== La Mood Box est activée lorsque l'utilisateur appuie sur la barre de laiton située au sommet de la boîte (cette barre est une extension de la touche capacitive installée à l'intérieur de la boîte). Cette activation est accompagnée d'une animation conjointe de la figurine, de l'anneau de LEDs et de l'écran LCD. Un nouvel appui déclenche le mode lecture. La première fois, la lecture de la musique démarre au tout début de la liste de lecture. Le bouton du potentiomètre est alors actif et permet de régler le volume de la musique jouée. La barre reste quant à elle disponible pour agir sur la musique jouée. Pendant la lecture, si la barre est touchée : * 1 fois : "pause/play", i.e. la musique est mise en pause ou en lecture suivant l'état précédent, avec un affichage spécifique sur l'écran LCD ; * 2 fois : "next", i.e. la lecture passe au titre suivant de la liste de lecture ; * 3 fois : "previous", i.e. la lecture repasse au titre précédent de la liste de lecture ; * 4 fois ou plus : retour au mode "veille", avec une animation conjointe de l'anneau de LEDs, de la figurine et de l'écran LCD. Remarque : chacune des actions pause/play/next/previous génère un changement de rotation de la figurine. Pendant la lecture, l'anneau de LEDs est en mode "arc-en-ciel" et la figurine tourne sur elle-même. ==== Désactivation de la Mood Box ==== Après activation de la Mood Box ou après l'arrêt volontaire de la musique, si aucun appui n'est effectué dans les 5 secondes, le mode veille reprend et la Mood Box est désactivée. Il est à noter que si l'on relance la lecture depuis le mode "veille", celle-ci va reprendre exactement là où on l'avait interrompue.ée.

- Easy Way to Add Tidal Music to iTunes Library + (iTunes allows users to not only access str … iTunes allows users to not only access streaming music, buy favorite tunes but also upload local files from other sources. It gives users one place to collect and listen to all music – including playlists, podcasts, streaming radio stations, local files, and more.
These days, I'm attracted by Tidal songs with HiFi quality. And I have subscribed to its HiFi subscription at 19.99 per month. But to my surprise, I failed to '''download music from Tidal to iTunes'''. Based on this situation, I have done some researches and found the reasons and the solution to achieve this goal.
To avoid you encountering the same confusion, I will share with you my successful experience of transferring Tidal music to iTunes library.
= Why You Can’t Download Music from Tidal to iTunes = Tidal provides over 70 million tracks with standard sound quality and HiFi sound quality for subscribers to enjoy music. Tidal is famous for its lossless audio quality. With a Tidal HiFi account, it's able to get lossless CD-quality and High-Res quality audio files. It could be a charming option for audiophiles. But like other streaming music services, Tidal has its own limitations. Users with any subscription can only play Tidal music on authorized players and its own player, the Tidal app, or Web Player. Because Tidal playlists can be downloaded as local files on mobile devices. (There is no Download option for Mac and Windows computers.) And there is no way to transfer Tidal songs to other players without authorization. Thus, if you'd like to download Tidal music to iTunes, a professional Tidal Music Downloader is necessary. It can not only download Tidal music to a computer but also convert Tidal songs to iTunes supported files. = Tool Required: AudFree Tidal Music Downloader = The tool I found is [https://www.audfree.com/tidable-music-converter/ AudFree Tidal Music Downloader], which hits on No.1 place in this field. It can download and export Tidal songs to common audio files, like MP3, FLAC, WAV, AAC. And it supports a Lossless output setting to encode Tidal songs losslessly. It can preserve the 100% lossless sound quality with ID3 tags. Now, let's see how to use it to download music from Tidal to iTunes library.

Au cours de cette formation, nous devons réaliser une Bentolux et choisir un dernier étage. Ce tutoriel décrit le troisième étage que j'ai choisi de fabriquer. Il s'agit d'un analyseur d'air ambiant que j'ai nommé VigiAir.
VigiAir va analyser le taux des principaux facteurs qui influencent la qualité de l’air de nos habitations : le taux de pollution, le taux de poussières, mais également le taux d’humidité et la température.

'''GENESE'''
Au commencement, Dieu créa.... (non j'déconne)
Avant de commencer la formation, je m'étais fabriqué un stand de tir pour airsoft dans mon vide sanitaire avec un système me permettant de relever les cibles tombées à l'aide d'une corde d'un peu moins de 10 mètres.
Dès que nous avons abordé Arduino dans la formation je me suis dit.... Bon, mon système à corde fonctionne mais ce serait beaucoup plus fun de remonter automatiquement les cibles et pourquoi pas de se créer en plus des séquences de jeu différentes.
Cette envie est restée dans un coin de ma tête jusqu'au jour où nous devions réfléchir au projet "fil rouge" caractérisé par la création du troisième étages de notre Bentolux.
Nous devions créer des binômes pour la réalisation de cette étage libre...
Lors d'une pause café avec mes camarades de formation, je leur partage l'idée d'un troisième étage "stand de tir". Renaud me dit, si tu veux on le fait ensemble.
A ce moment là de la formation, je ne connaissais pas encore tout le monde et je ne savais pas que Renaud est un adepte de GN (jeu de rôle grandeur nature).
Pour ces parties de Shadowrun, il utilise des Nerf qu'il customise (entre autres accessoires) avec sa team.
Autant dire que la perspective de dégommer des cibles au Nerf n'était pas pour lui déplaire.
C'est ainsi que commença la créative et rocambolesque collaboration de deux quadras adulescents à la chevelure fantomatique.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
'''REPARTITION DES TACHES'''
Afin d'optimiser le temps qui nous était imparti ([https://fr.wikipedia.org/wiki/Gandalf ;-)]), nous nous sommes répartis les différentes tâches ainsi:
Renaud
-Création du "gros oeuvre" sur Inkscape (box entourant les deux premiers étages de la Bentolux).
-Création des fantômes sur Inkscape (cibles+ceux en plexi des faces de la box).
-Découpe laser de la box, du deuxième étage et des cibles fantômes en contreplaqué.
-Découpe laser des fantômes en plexi vert incrusté sur les faces avant et latérales de la box.
-Assemblage et collage de la box et du deuxième étage de la Bentolux.
-Collage des fantômes en plexi dans les trous des faces de la box.
-Rédaction de toutes les étapes de la doc du Wikifab.
Mayak
-Création d'une maquette pour se représenter le mécanisme des cibles avec le système de relevage.
-Création sur Inkscape des pièces constitutives au mécanisme des cibles et celui du remonte-cible actionné par le servomoteur.
-Assemblage, collage, perçage et ajustement de toutes les pièces avec les microrupteurs et servomoteur.
-Création dans fusion 360 du bouton du potar (imprimé, installé, mais que nous n'utiliserons finalement pas dans notre version de base actuelle)
-Montage et câblage des composants électroniques sur la box et l'arduino.
-prise de vues (photos et vidéos) pour illustrer la doc du Wikifab.
Pour ce qui est du code nous y avons travaillé ensemble. Pour cette version de base, nous avons du revoir à la baisse nos ambitions par manque de temps, mais nous comptons faire évoluer cette box que ce soit en terme de séquences/modes de jeu ou en nombre de modules additionnels de cibles.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
'''MATOS & OUTILS'''
-Panneau de CP peuplier 3mm (plus épais pour la plateforme serait mieux)
-Panneau de Plexiglass vert
-1 tige fileté de 6mm
-des écrous et rondelles de 6mm
-Scie à métaux
-Pince, serre-joint
-Equerre,règle, crayon...patience et minutie
-Perceuse à colone (ou perceuse...)
-Fer à souder
-Clé plate de 6mm (deux c'est mieux ou avec une pince à bec pour serrer les écrous entre eux)
-Colle à bois
-Colle à chaud (pistolet)
-Colle forte Super Glue (pour les aimants)
-1 Arduino Uno
-1 breadboard
-des fils électriques (beaucoup)
-5 leds
-5 résistances 220 kΩ
-1 servomoteur
-3 microrupteurs
-1 potar (sera utilisé dans la V2)
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
'''NOS PETITES GALERES (génératrices d'astuces et de partages)'''
Evidement nous avons dû résoudre deux trois petits soucis...
-la taille de notre box étant relativement importante, le CP de peuplier de 3mm est un peu trop fin et de fait la stabilité du plancher où repose le mécanisme des cibles n'est pas parfaitement plane.
-il a fallu lester les cibles avec un boulon afin qu'elles actionnent correctement les microrupteurs lors de leur chute.
-Nous avons préféré utiliser des aimants plutôt que les band "scratch" initiales pour maintenir plus surement les cibles à la verticales.
-Le potar ne rentrait pas dans le trou du bouton imprimé en PLA (c'était ma première impression), quelques secondes au mini décapeur thermique ont suffit pour régler le soucis.
J'en oublie surement plein mais du coup j'en profite pour remercier toutes les personnes du FabLab qui nous ont apporté leurs lumières (ou simplement indiqué l'emplacement d'outils) dans les phases obscures de notre projet.
Maxime, Gael, Thibaud, (les)Michaël... et Hubert évidement qui a su nous faire redescendre sur terre sans jamais nous couper les ailes ;-)

'''3. Programme en boucle ouverte'''
Pour tester la programmation, nous simulons le programme dans ISIS, comme on peut le voir sur la figure suivante. De plus, nous avons un afficheur LCD pour afficher des données (rapport cyclique correspondant à la PWM à 32Khz, le courant moteur, la tension moteur, l'action sur les boutons poussoirs. En effet, 4 boutons poussoirs sont utilisés.
BP1 pour incrémenter manuellement le rapport cyclique, BP2 le décrémenter. BP3 mettre le rapport cyclique à 0, correspondant au contact frein.
La vitesse du moteur est pratiquement proportionnelle au rapport cyclique
https://i58.servimg.com/u/f58/17/56/35/17/a211.jpg
Nous avons réalisé notre propre amplificateur de courant qui s'appelle un hacheur abaisseur mais il est possible d'acheter un shield
Il existe de nombreuses cartes pour Arduino pour commander des moteurs DC surtout de faibles puissances et aussi de grandes puissances comme on peut l'observer sur les liens suivants.

https://i58.servimg.com/u/f58/17/56/35/17/a310.jpg
mais, tous ces hacheurs shields mesurent le courant en interne mais il n'y a pas de limitation de courant.
Pour avoir une limitation de courant il faut une boucle de courant analogique en utilisant des AOP ou CI spécialisée ou une boucle de courant numérique rapide.
Mais quel doit être la valeur du courant de limitation ?
Le choix de la valeur du courant est normalement pour le Service de fonctionnement 1 heure pour pouvoir effectuée des montées relativement longue sans atteindre la température critique du moteur.
Dans notre cas, le courant de limitation devra etre de
Imoteur limitation=Puissance/Ubatterie=500W/24 V=20A
De plus, le transistor de puissance du hacheur ne peut supporter que 50A dans notre cas.
Mais en boucle ouverte, il n'a pas de régulation de courant, pour ne pas avoir de dépassement du courant maximum, une rampe du rapport cyclique sera utilisé.
Une routine d'interruption de 0.1 seconde sera utilisé pour faire la mesure de la tension est du courant (échantillon de mesure, sample ). Ce temps de sampler est arbitraire, mais ne permet pas d'être plus rapide que le temps de montée du courant car la constante de temps électrique du moteur étant de L/R= 1.5ms.
Le fonctionnement en boucle ouverte avec une rampe de 25.5s (8bit et routine d'interruption de 0.1s) permet de bien comprendre la problématique du fonctionnement d'une commande à moteur DC.
l'affichage se fera seulement tous les 0.2s pour avoir une stabilité des chiffres à l’écran. De plus, un filtrage numérique, se fera sur le courant et la tension sur 4 valeurs donc sur 0.4s.

Une porte à poules est destiné à automatiser l’ouverture et la fermeture d’un poulailler. Il est équipé d’un capteur de lumière et d’une horloge en temps réel. Le déclenchement de la porte se fait donc à partir d’une certaine heure (défini par l’utilisateur au moyen de potentiomètres) et quand la lumière passe en dessous d’un certain seuil. gt;Et plein d'autres doc ici : https://www.guillaumeleguen.xyz/wiki/?PagePrincipale</nowiki>)
Le système est réalisé sur une base arduino avec un moto-réducteur à courant continu. L’alimentation est opéré par une batterie au plomb chargé par un petit panneau solaire.
La version actuelle n'est pas à un niveau de fonctionnement satisfaisant. Il reste encore à trouver la bonne motorisation.

The following tips can help you stay on top of things and get through the work without getting lost in the details: Get a first impression of the relevance of the work by looking at the table [https://paperwriter.pro/ paper writer] of contents, the bibliography, and possibly the biographical information about the author: does it really deal with your topic? What is the author's scientific background and orientation? Is he/she a specialist in the field or new to the field? When cross-reading, always keep your question for the text in mind and critically examine whether and for what you can and would like to use the text. Have the "courage to leave gaps": When you first read the text, leave out chapters or passages that lead you too far away from your question! Note down ideas, associations and cross-references already during the first reading: Even if you are sure that this or that thought is obvious - it often does not come a second time ... Various institutions offer courses in speed reading, which train you to quickly grasp the content of texts without reading word for word. If you are interested in this: Acquire this technique in advance so that you are prepared for the emergency! '''Structuring the material''' Reading and editing your sources in a structuring way is a necessary endeavor, and it also has many benefits: It makes the content of the text clearer; books don't have to be read repeatedly; you create "material" for yourself that you can work with further without problems. With the systematic reading, editing and excerpting of readings, you create material for yourself with which you can continue to work in a well-founded manner. The excerpted material is a first text form that you have created in keywords. The next step is the first formulation of your keywords in complete sentences. The resulting text represents the skeleton of a rough draft, which will be edited again in later work phases, supplemented by further excerpts and quotations, evaluated, etc. '''Excerpting''' Excerpting means to grasp the content of a text, to filter out the core elements and to summarize them in one's own words in as short and concise a form as possible. If such an excerpt contains directly (1:1) adopted passages (quotations), these must be recorded with the correct source citation and indicated in quotation marks in case of a later adoption. Excerpting is a very important skill that you need from the beginning. In order to [https://paperwriter.pro/buy-lab-report-online/ write my lab report] be able to take any useful notes at all on the particular articles you read, it is essential to read and summarize texts correctly in your own words. This activity will accompany you during your whole working process around the creation of the scientific paper. Very important: The page count of the excerpted text should always be significantly shorter than the original!

- Spinning Kinetic Sculpture RGB + (<big>Greeting to you Maker !</big … Greeting to you Maker ! Are you curious? Do you like interior decorations that animate and create a beautiful visual show and yet you don't know how to make a Kinetic Sculpture? Then this tutorial is for you :) If you want to watch what the final result looks like: I made a [https://www.youtube.com/playlist?list=PL_7tLqqQRSR_Xd5aRAs7i2mpFPNkJYd6S Youtube Playlist].' This Spinning Kinetic Sculpture RGB is a sculpture you can fix on a wall or on a support. It is made of 2 main identical wheels that spin in opposite direction, which is creating constructive and destructive visual interferences, it is called the phenomenon of [https://en.wikipedia.org/wiki/Moir%C3%A9_pattern Moiré]. The concept is purely kinetic (spring), it allows the wheels to spin at different and irregular speeds but most importantly to run for a long time (+30minutes). After you rewind the mechanism the wheels start to spin in opposite direction. As soon as the gravity makes the front wheel reverse its spinning direction and pushes some pawls in the system, the 2 wheels are pushed and start to spin again. This is happening until the spring is fully unwinded. If properly optimised and by reducing the friction, it is possible to get a runtime of more than an hour! I got my inspiration from pre-existing kinetic sculptures, but I decided to make my own design and my own version of the mechanism which is the crucial point of the sculpture. Until the day, I tried, made, changed and improved my design and finally made a fresh new version by accumulating all my efforts and previous trials. The result is a fully working Kinetic Sculpture that costs almost nothing and more importantly: the size of the mechanism is twice smaller than other documented kinetic sculpture online! You can also fix it to a support like a mounting base of a screen which will allow you to move it around but a wall will give you a far better looking result. The center of gravity of the wheel is placed so it acts like a pendulum. The radius of the pendulum plays a major role in the total runtime of the sculpture. It can look complex on the first sight but if you look more closely at each step you will see that it is fairly easy. It is also very instructive because you start to understand that every piece plays a major role in the running of the sculpture. You end up with an almost magical piece of art that creates spectacular effects! You can complete the sculpture with an RGB LED Ring connected to an Arduino, an ON/OFF switch and a battery so it looks even more amazing. Please note that only the LEDs need an electrical source of energy. You can choose to not use the LEDs, it's up to you. You're only limited by your own imagination. Understanding the mechanism doesn't seem easy at first sight but that's exactly why I documented everything and wrote this tutorial with plenty of pictures and videos. What was a pain in the ass for me is going to be very easy for you. Isn't it why Internet exist? to be very easy for you. Isn't it why Internet exist?)

The CCSK is the industry-leading standard for measuring cloud security skills. Recently, the CCSK has been proposed as the most valuable IT certification. CSA provides the best possible guidance to its members and the information security community at large. It is intended to demonstrate the changing landscape of cloud computing security. This course includes the latest version of CCSK i.e. 4.0. This course will introduce participants to different modules compared to cloud security and knowledge security from a governmental, legal, and compliance perspective. Associates will learn the technical details of implementing security. This CCSK course will also make it easier for participants to prepare for the [https://dumps4free.com/CCSK-exam-questions-pdf-vce.html '''CCSK certification exam''']. == '''About the Cloud Security Alliance:''' == Cloud Security Alliance (CSA) is the main worldwide association focused on recognizing and bringing issues to light of best practices to guarantee a protected distributed computing climate. CSA provides the subject matter expertise of industry professionals, associations, governments, and their corporate and individual members to enable research, education, certifications, events, and specific cloud security products. CSA's activities, knowledge, and exceptional network benefit the entire cloud affected community, from vendors and customers to governments, business, and the insurance industry, and provide a forum in which multiple people can work together to create and maintain a committed cloud environment. == '''How is the CCSK certification different from other IT certifications?''' == CCSK is one of the few certifications that focus specifically on cloud security. Many other IT degrees take a general approach to security topics or have a deep level of position in another area in the field of information security, digital forensics, reverse engineering, etc. Instead, the CCSK is designed to assess knowledge of applying cloud security tools, techniques, and methods to cloud computing. Due attention is given to drawing attention to the points where cloud computing needs a different form of security. CCSK isn't the only cloud-focused certification available. Cloud service providers and other certification organizations have developed many other certifications to assess candidates' knowledge of cloud computing concepts and technology. However, CCSK focus on cloud security helps set it apart from these other certifications. == '''Should I take a CCSK exam?''' == The CCSK is designed to allow cloud security professionals to demonstrate their knowledge and skills in this specific area. Roughly speaking, the test content focuses on cloud computing, theory, and the tools and techniques required to successfully secure it. The CCSK exam experience requirements mean that it is not an excellent option for those just out of college looking to major in cloud computing. The five-year IT terms show that the test is intended for intermediate-level security professionals, not beginners. On the other hand, if you need to get into the realm of cloud security, this test might be for you. If you have the experience except for a cloud security background, consider looking for [https://dumps4free.com/vendor/Cloud%20Security%20Alliance Certified Cloud Security Knowledge (CCSK)]. This allows you to let go of the need to try CCSK cloud security and use certification to make it easier for you to get a job in the field. Hence, we see that everyone new to Cloud Security can choose CCSK, and for all IT professionals who are already working in the field, CCSK is a golden opportunity. You could do much worse than focus on cloud security as your primary direction of career development and enhancement. Willingness to leap mainly depends on meeting reasonable expectations that cloud computing should be safe and secure. Providing the expertise and knowledge to meet those expectations cannot fail to be a great hook on which to suspend the future of IT. === '''Conclusion''' === Having a CSA certification is not a guarantee of employment or job security, but companies prefer certified knowledge that resources possess when they join their company. Seller neutral testimonials tend to make sense because they open up a more inclusive market rather than specific seller markets. But this depends on your condition. People with less experience should start with the basic certification and obtain other, more advanced, and specific degrees. Eligible candidates can seek specialization as their expertise can help them add more value to cloud security.elp them add more value to cloud security.)
