Introduction

This modular box is a 3-tier set. Once on, it provides basic weather station information (temperature, humidity, atmospheric pressure) but becomes a "Mood box", here a jukebox actually, when properly activated.

Preamble

This project is a group project (FaB team) carried out during a French hybrid training program called "Fabrication numérique" (CNC machining and fabrication) - class of 2018, July.

This final group project involves some of the know-how acquired during the training program and seals the deal. It is complementary with the "Bentolux" project which should be documented and referenced soon on wikifab.org.

Instructions for the project were:

• create a new tier to the box designed and developed during the course of the training program (3 available tiers: 1 base, 1 in Plexiglas, 1 for LCD screen);
• use newly acquired knowledge for this new tier: 3D printing, laser cutting, etc.;
• program with Arduino at least one user interaction (free choice).

Overall specifications

After some thought our group decided to create a musical tier - we called it "Mood box" - to complement the weather station using the base-tier and the LCD-tier.

Expected behavior is described here below.

Starting the box

When properly plugged in, the box can be started by using the switch on the front.

Starting the box triggers the following events:

• figurine set on top spins on its stand;
• LED-ring light effect shows through the figurine's translucent stand;
• LCD screen displays a welcome message.

If no other action is made right away, the box goes in "sleep mode".

In "sleep mode", temperature and humidity are displayed with a custom message on LCD screen.

These custom messages as well as the color set for both the LED-ring and LCD screen depend on current temperature:

• LCD and LED-ring color varies from blue to red when temperature rises;
• LED-ring sparkles at a random frequency to add some animation;
• custom message is displayed on LCD screen according to the temperature range currently reading.

Mood box activation and functionalities

Mood box is activated when the user touches the brass bar placed on top of it - this bar is connected to a capacitive sensor set inside the box.

Upon activation, figurine, LED-ring and LCD wake up.

Cette activation est accompagnée d'une animation conjointe de la figurine, de l'anneau de LEDs et de l'écran LCD.

If no other tap is made within 5 seconds following activation, Mood box is deactivated and goes back into sleep mode.

A new tap triggers play mode.

Using the bar has been made simple: the LED-ring shows current tap count as it grows - from 1 to 4 LEDS lit in white

First time, playlist begins with the first title on the list.

The potentiometer button - placed under the on/off switch on the front - is then active and serves as volume control for music.

The brass bar remains also active and stands by pending new user interaction.

While music plays, action differs depending on how many times the bar is touched:

• 1 tap: "pause/play", i.e. the music is paused if playing before or begins playing if paused before and LCD displays a message accordingly;
• 2 taps:"next", i.e. the player jumps to the next title on the list;
• 3 taps:"previous", i.e. the player changes the current title for the previous one;
• 4 taps or more: "stop", i.e. the box returns to sleep mode after a short animation of figurine, LED-ring and LCD screen.

During play time, LED-ring lights up in a rainbow sequence and figurine spins on top of its stand.

Note: Each time a play/pause/next/previous action is taken into account, figurine spins in other direction.

Deactivating the Mood box

After activating the Mood box or when the music is stopped, if the bar remains idle for more than 5 seconds, sleep mode kicks in and deactivation occurs.

Note: When exiting sleep mode to play the music again, the player starts from where it was when deactivated.
