{{ {{tntn|Tuto Step}}
|Step_Title=Overview
|Step_Content=The PPP charging device gives an alternative for charging your computer. You will be pedaling on your ordinary bicycle while on a bike stand. The bike stand has a generator that is turned by the bicycle wheel by a roller. The power coming from the generator is converted to the DC voltage your computer needs to charge. We are adding a display in between to monitor the production.

|Step_Title=Generator : mechanical to electric energy
|Step_Content=the generator makes energy when you roll it. It is converting the movement of rotation to electricity.

DC generator / electrical scooter

Voltage : 24V or 36V

Power : 100-250W

https://www.ebay.com/itm/ZY-MY-1016-Electric-Motor-DC-36v-250w-Brushed-E-Bike-Scooter-36-Volt-250-Watt-/162623837901

You can find any electric motor with the same specifications to do the job. The motor drives a scooter when powered. When used the other way round it generates electricity when turned at a high speed.

|Step_Title=Bicycle stand : dynamic energy to static energy
|Step_Content=The bicycle stand keeps your bike into place. It is rather critical. It carries your bike while it drives the generator. In stead of putting your energy in transporting yourself, you are putting energy in the generation of electricity.

Look for a bicycle stand that has :

*Tightening screws that fit your bike axle.
*A roller that can be removed.
*Search for second hand bicycle stands.
*It should fit your bicycle and it should hold the generator at a good tension to your wheel.
|Step_Picture_00=People_pedal_powered_computer_charger_DSC05295.jpg
}}
{{ {{tntn|Tuto Step}}
|Step_Title=Back to the bicycle stand
|Step_Content=We start with the bicycle stand. First remove the roller of the stand. We will make a new roller that can be put on the generator. Keep the bold and nut that hold the moving part to the bike stand. Also keep the screw that changes the tension on the roller.

 
|Step_Picture_00=People_pedal_powered_computer_charger_ppp_comp_charger.png
}}
{{ {{tntn|Tuto Step}}
|Step_Title=Mounting the generator to the bike stand
|Step_Content=Then we will make our own fixation for the generator. Find a metal joiner that can make a piece that can hold the generator. We're using a steel tube of 40x80mm.

Follow the plan if you happen to have the same bicycle generator. If not, verify the measures!

The two first horizontal holes are there for the axle of the old bicycle roller. The second vertical hole leaves place for the adjusting screw. This allows to adjust the tension of the bicycle wheel. The last four holes are there to hold the generator. Check this with the generator you have.

Now make a part in wood. Use a vertical drill for the holes, it will make them more precise. This piece allows to place the roller of the generator in the middle.

Note : we changed the model afterwards and we removed a part of the metal so we could adjust the position more easily.

Note : if the generator is too close to the wheel of the bicycle, then make the wooden part larger. Place the generator higher on the wood to create more place.

{{ {{tntn|Tuto Step}}
|Step_Title=Roller : slow- to fast-rotation mechanical energy
|Step_Content=We're making a new roller for the generator. The roller is converting the slow-turning mechanical energy of the bicycle wheel to a fast-turning mechanical energy. Electric generators like high speeds.

Find a metal joiner or a lathe to make the piece. We are using a steel bar of 40mm diameter.

Make the metal piece based on the plan. We found that a roller diameter of 40mm gives good results. The center hole should be the same diameter as the axle of the generator.

|Step_Picture_01=People_pedal_powered_computer_charger_PPP_computer_charger_6-1.png
}}
{{ {{tntn|Tuto Step}}
|Step_Title=Testing the stand and generator
|Step_Content=Fix the roller on the generator.

Gently hit the roller on the axle of the generator and fix the roller with a M4 screw. If the roller doesn't fit you can heat the piece so the hole becomes bigger.

Verify the regular turning of the roller.. Test if the roller is centered and is turning regular. This is to avoid vibrations an wear of the bicycle.

Mount the generator with its roller to the wood piece. Then fix the wood piece to the mounting piece. Hold the mounting piece in place with the bold and nut of the moving part. Put back the screw for adjusting the tension of the roller.

Now check if the wheel is touching the roller correctly. Can you put enough tension on the roller? You should feel some resistance when you are pedaling on the bike.

This is not an easy part so be ready for some adjusting and testing again.

|Step_Title=Conversion : messy DC power to flat DC voltage
|Step_Content=Now we're ready for tackling the energy part. The power that will be generated is a messy DC voltage. We want to flatten this out to the charging voltage of your computer.

We need a DC/DC converter.

Input : min computer voltage (20V) to min 40V

Output : min computer voltage (20V)

Current : min computer current (4.5V)

Instructions :

- connect the display to the converter.

Solder/screw the display to the cable end of the input of the converter. You can choose the connector type. (For [https://ciklic.wordpress.com/2017/08/09/dc-connectors/ some inspiration] in Dutch)

- don't overcharge your computer.

When you are approaching 100% charge you should be extremely careful to not put too much power. The current must AT ALL TIMES stay lower than the current indicated on your adapter.

- don't blow up the converter.

Again when you approach full charge be careful to not put too much power. The voltage should AT ALL TIMES stay lower than the 40V that is indicated on the converter.

|Step_Title=Charging : adapting to the computer voltage
|Step_Content=The aim of the people pedal power is to charge a computer. A computer battery is normally charges by an adapter that converts AC mains power to DC power. This charger will be only for YOUR computer.

Material :

- touch-safe connectors with locking

female http://se.rs-online.com/web/p/xlr-connectors/0405590/

male http://se.rs-online.com/web/p/xlr-connectors/0405607/

We want to charge with the same power as the adapter does.

Check the voltage and the current at which the adapter charges your computer. Mine charges at 20V and 4.5A.

You can also chose to buy a new computer plug separately and assemble a new cable for the PPP device.

{{ {{tntn|Tuto Step}}
|Step_Title=Making the circuit
|Step_Content=The PPP device will charge your computer in stead of the adapter. Cut the cable in between the adapter and the computer plug. Solder/screw the new plugs to the cut wires. Female to the adapter side, male to the computer plug side.

Solder the converter into the circuit.

Screw the output to a pair of cables that is convenient for you, say 1m of 1.5mm2. Solder/screw the same female plug as above to the other end of the cable. This is the point where you can connect your computer plug.

Screw the input to a pair of cables, again 1m of 1.5mm2. This is the point where the display will be connected.

- protect the converter.

You may want to protect the converter ant put it in a box of a non-conducting material.

Wire up the generator to the circuit.

Solder/screw the generator to a pair of cables, 2m 1.5mm2. Solder/screw the cable end to the display. You can choose to use the same plugs as before to be able to disconnect the bicycle stand from the electronics. Female to the generator side, male to the display side.

|Step_Title=Bicycle : human energy to mechanical energy
|Step_Content=This etape is the conversion of the human energy to slow-rotating mechanical energy. We are using an ordinary bicycle to harvest the energy.

Your bike should have low-profile tires. When the profile is too important (see picture) there will be a large energy loss due to vibrations. You will also have more noise when pedaling.

The fixation of the axis should be not of the fast-release type. The fast-release-type with flat end (se picture) is often not compatible with the bike stands. You can easily change the axle with another (second hand) axle.

|Step_Title=Charging more than a computer
|Step_Content=PS :

If you want to charge other batteries than that of your computer, you can make more electronics circuits. Repeat the steps until the step of conversion. You can than plug the converter you need to the PPP device.

|Step_Title=Overview
|Step_Content=The PPP charging device gives an alternative for charging your computer. You will be pedaling on your ordinary bicycle while on a bike stand. The bike stand has a generator that is turned by the bicycle wheel by a roller. The power coming from the generator is converted to the DC voltage your computer needs to charge. We are adding a display in between to monitor the production.

|Step_Title=Generator : mechanical to electric energy
|Step_Content=the generator makes energy when you roll it. It is converting the movement of rotation to electricity.

DC generator / electrical scooter

Voltage : 24V or 36V

Power : 100-250W

{{ {{tntn|Tuto Step}}
|Step_Title=Back to the generator
|Step_Content=Wire up the generator to the circuit.

Solder/screw the generator to a pair of cables, 2m 1.5mm2. Solder/screw the cable end to the display. You can choose to use the same plugs as before to be able to disconnect the bicycle stand from the electronics. Female to the generator side, male to the display side.

{{ {{tntn|Tuto Step}}
|Step_Title=Bicycle stand : dynamic energy to static energy
|Step_Content=The bicycle stand keeps your bike into place. It is rather critical. It carries your bike while it drives the generator. In stead of putting your energy in transporting yourself, you are putting energy in the generation of electricity.

Look for a bicycle stand that has :

*Tightening screws that fit your bike axle.
*A roller that can be removed.
*Search for second hand bicycle stands.
*It should fit your bicycle and it should hold the generator at a good tension to your wheel.

}}
{{ {{tntn|Tuto Step}}
|Step_Title=Back to the bicycle stand
|Step_Content=We start with the bicycle stand. First remove the roller of the stand. We will make a new roller that can be put on the generator. Keep the bold and nut that hold the moving part to the bike stand. Also keep the screw that changes the tension on the roller.

 
}}
{{ {{tntn|Tuto Step}}
|Step_Title=Mounting the generator to the bike stand
|Step_Content=Then we will make our own fixation for the generator. Find a metal joiner that can make a piece that can hold the generator. We're using a steel tube of 40x80mm.

Follow the plan if you happen to have the same bicycle generator. If not, verify the measures!

The two first horizontal holes are there for the axle of the old bicycle roller. The second vertical hole leaves place for the adjusting screw. This allows to adjust the tension of the bicycle wheel. The last four holes are there to hold the generator. Check this with the generator you have.

Now make a part in wood. Use a vertical drill for the holes, it will make them more precise. This piece allows to place the roller of the generator in the middle.

Note : we changed the model afterwards and we removed a part of the metal so we could adjust the position more easily.

Note : if the generator is too close to the wheel of the bicycle, then make the wooden part larger. Place the generator higher on the wood to create more place.
}}
{{ {{tntn|Tuto Step}}
|Step_Title=Roller : slow- to fast-rotation mechanical energy
|Step_Content=We're making a new roller for the generator. The roller is converting the slow-turning mechanical energy of the bicycle wheel to a fast-turning mechanical energy. Electric generators like high speeds.

Find a metal joiner or a lathe to make the piece. We are using a steel bar of 40mm diameter.

Make the metal piece based on the plan. We found that a roller diameter of 40mm gives good results. The center hole should be the same diameter as the axle of the generator.
|Step_Picture_00=People_pedal_powered_computer_charger_20170505_213825.jpg
|Step_Picture_01=People_pedal_powered_computer_charger_PPP_computer_charger_6-1.png
}}
{{ {{tntn|Tuto Step}}
|Step_Title=Testing the stand and generator
|Step_Content=Fix the roller on the generator.

Gently hit the roller on the axle of the generator and fix the roller with a M4 screw. If the roller doesn't fit you can heat the piece so the hole becomes bigger.

Verify the regular turning of the roller.. Test if the roller is centered and is turning regular. This is to avoid vibrations an wear of the bicycle.

Mount the generator with its roller to the wood piece. Then fix the wood piece to the mounting piece. Hold the mounting piece in place with the bold and nut of the moving part. Put back the screw for adjusting the tension of the roller.

Now check if the wheel is touching the roller correctly. Can you put enough tension on the roller? You should feel some resistance when you are pedaling on the bike.

This is not an easy part so be ready for some adjusting and testing again.

{{ {{tntn|Tuto Step}}
|Step_Title=Conversion : messy DC power to flat DC voltage
|Step_Content=Now we're ready for tackling the energy part. The power that will be generated is a messy DC voltage. We want to flatten this out to the charging voltage of your computer.

We need a DC/DC converter.

Input : min computer voltage (20V) to min 40V

Output : min computer voltage (20V)

Current : min computer current (4.5V)

|Step_Content=The bicycle stand keeps your bike into place. It is rather critical. It carries your bike while it drives the generator. In stead of putting your energy in transporting yourself, you are putting energy in the generation of electricity.

Look for a bicycle stand that has :

*Tightening screws that fit your bike axle.
*A roller that can be removed.
*Search for second hand bicycle stands.
*It should fit your bicycle and it should hold the generator at a good tension to your wheel.

|Step_Title=Mounting the generator to the bike stand
|Step_Content=Then we will make our own fixation for the generator. Find a metal joiner that can make a piece that can hold the generator. We're using a steel tube of 40x80mm.

Follow the plan if you happen to have the same bicycle generator. If not, verify the measures!

The two first horizontal holes are there for the axle of the old bicycle roller. The second vertical hole leaves place for the adjusting screw. This allows to adjust the tension of the bicycle wheel. The last four holes are there to hold the generator. Check this with the generator you have.

Now make a part in wood. Use a vertical drill for the holes, it will make them more precise. This piece allows to place the roller of the generator in the middle.

Note : we changed the model afterwards and we removed a part of the metal so we could adjust the position more easily.

Note : if the generator is too close to the wheel of the bicycle, then make the wooden part larger. Place the generator higher on the wood to create more place.

|Step_Title=Roller : slow- to fast-rotation mechanical energy
|Step_Content=We're making a new roller for the generator. The roller is converting the slow-turning mechanical energy of the bicycle wheel to a fast-turning mechanical energy. Electric generators like high speeds.

Find a metal joiner or a lathe to make the piece. We are using a steel bar of 40mm diameter.

Make the metal piece based on the plan. We found that a roller diameter of 40mm gives good results. The center hole should be the same diameter as the axle of the generator.

|Step_Title=Overview
|Step_Content=The PPP charging device gives an alternative for charging your computer. You will be pedaling on your ordinary bicycle while on a bike stand. The bike stand has a generator that is turned by the bicycle wheel by a roller. The power coming from the generator is converted to the DC voltage your computer needs to charge. We are adding a display in between to monitor the production.

|Step_Title=Bicycle stand : dynamic energy to static energy
|Step_Content=The bicycle stand keeps your bike into place. It is rather critical. It carries your bike while it drives the generator. In stead of putting your energy in transporting yourself, you are putting energy in the generation of electricity.

Look for a bicycle stand that has :

*Tightening screws that fit your bike axle.
*A roller that can be removed.
*Search for second hand bicycle stands.
*It should fit your bicycle and it should hold the generator at a good tension to your wheel.

|Step_Title=Conversion : messy DC power to flat DC voltage
|Step_Content=The power that will be generated is a messy DC voltage. We want to flatten this out to the charging voltage of your computer.

Material :

- DC/DC converter

Input : min computer voltage (20V) to min 40V

Output : min computer voltage (20V)

Current : min computer current (4.5V)

https://www.benl.ebay.be/itm/8A-DC-DC-BUCK-CONVERTER-STEP-DOWN-8-40V-TO-1-25-36V-WITH-CURRENT-CONTROL-XL4016-/181653531755?

Instructions :

- solder the converter into the circuit.

Screw the output to a pair of cables that is convenient for you, say 1m of 1.5mm2. Solder/screw the same female plug as above to the other end of the cable. This is the point where you can connect your computer plug.

Screw the input to a pair of cables, again 1m of 1.5mm2. This is the point where the display will be connected.

- protect the converter.

You may want to protect the converter ant put it in a box of a non-conducting material.

Then we will make our own fixation for the generator. Find a metal joiner that can make a piece that can hold the generator. We're using a steel tube of 40x80mm.

Follow the plan if you happen to have the same bicycle generator. If not, verify the measures!

The two first horizontal holes are there for the axle where the old bicycle roller was fixed. The second vertical hole leaves place for the adjusting screw. This allows to adjust the tension of the bicycle wheel. The last four holes are there to hold the generator. Check this with the generator you have.

Note : we changed the model afterwards and we removed a part of the metal so we could adjust the position more easily.

Instructions :

- we want to charge with the same power as the adapter does.

Check the voltage and the current at which the adapter charges your computer. Mine charges at 20V and 4.5A.

- you will be cutting your power cable.

The PPP device will charge your computer in stead of the adapter. Cut the cable in between the adapter and the computer plug. Solder/screw the new plugs to the cut wires. Female to the adapter side, male to the computer plug side.

You can also chose to buy a new computer plug separately and assemble a new cable for the PPP device.

Solder/screw the display to the cable end of the input of the converter. You can choose the connector type. (For [https://ciklic.wordpress.com/2017/08/09/dc-connectors/ some inspiration] in Dutch)

- don't overcharge your computer.

When you are approaching 100% charge you should be extremely careful to not put too much power. The current must AT ALL TIMES stay lower than the current indicated on your adapter.

- don't blow up the converter.

Again when you approach full charge be careful to not put too much power. The voltage should AT ALL TIMES stay lower than the 40V that is indicated on the converter.

|Step_Content=The roller is converting the slow-turning mechanical energy of the bicycle wheel to a fast-turning mechanical energy. Electric generators like high speeds.

Material :

- steel bar of 40mm diameter

Instructions :

- find a metal joiner or a lathe to make the piece.

Make the metal piece based on the plan. We found that a roller diameter of 40mm gives good results. The center hole should be the same diameter as the axle of the generator.

- fixate the roller on the generator.

Gently hit the roller on the axle of the generator and fixate the roller with a M4 screw. If the roller doesn't fit you can heat the piece.

- verify the regular turning of the roller.

Verify if the roller is centered and is turning regular. This is to avoid vibrations an wear of the bicycle.

Material :

- ordinary bicycle

Your bike should have low-profile tires. When the profile is too important (see picture) there will be a large energy loss due to vibrations. You will also have more noise when pedaling.

The fixation of the axis should be not of the fast-release type. The fast-release-type with flat end (se picture) is often not compatible with the bike stands. You can easily change the axle with another (second hand) axle.

|Step_Content=The bicycle stand keeps your bike into place. It is rather critical. It carries your bike while it drives the generator. In stead of putting your energy in transporting yourself, you are putting energy in the generation of electricity.

Look for a bicycle stand that has :

* Tightening screws that fit your bike axle.
* A roller that can be removed.
* Search for second hand bicycle stands.
* It should fit your bicycle and it should hold the generator at a good tension to your wheel.

Steel tube 40x80mm

Instructions :

- find a bicycle stand.

- find a metal joiner that can make a piece that can hold the generator.

Follow the plan if you happen to have the same bicycle generator. The two first horizontal holes are there for the axle where the old bicycle roller was fixed. The second vertical hole leaves place for the adjusting screw. This allows to adjust the tension of the bicycle wheel. The last four holes are there to hold the generator. Check this with the generator you have.

Instructions :

- connect the display to the converter.

Solder/screw the display to the cable end of the input of the converter. You can choose the connector type. (For [https://ciklic.wordpress.com/2017/08/09/dc-connectors/ some inspiration] in Dutch)

- don't overcharge your computer.

When you are approaching 100% charge you should be extremely careful to not put too much power. The current must AT ALL TIMES stay lower than the current indicated on your adapter.

- don't blow up the converter.

Again when you approach full charge be careful to not put too much power. The voltage should AT ALL TIMES stay lower than the 40V that is indicated on the converter.

|Step_Title=Roller : slow- to fast-rotation mechanical energy
|Step_Content=The roller is converting the slow-turning mechanical energy of the bicycle wheel to a fast-turning mechanical energy. Electric generators like high speeds.

Material :

- steel bar of 40mm diameter

Instructions :

- find a metal joiner or a lathe to make the piece.

Make the metal piece based on the plan. We found that a roller diameter of 40mm gives good results. The center hole should be the same diameter as the axle of the generator.

- fixate the roller on the generator.

Gently hit the roller on the axle of the generator and fixate the roller with a M4 screw. If the roller doesn't fit you can heat the piece.

- verify the regular turning of the roller.

Verify if the roller is centered and is turning regular. This is to avoid vibrations an wear of the bicycle.

|Step_Title=Bicycle : human energy to mechanical energy
|Step_Content=This etape is the conversion of the human energy to slow-rotating mechanical energy. We are using an ordinary bicycle to harvest the energy.

Material :

- ordinary bicycle

Your bike should have low-profile tires. When the profile is too important (see picture) there will be a large energy loss due to vibrations. You will also have more noise when pedaling.

The fixation of the axis should be not of the fast-release type. The fast-release-type with flat end (se picture) is often not compatible with the bike stands. You can easily change the axle with another (second hand) axle.

The bike stands we designed fit regular bikes. The bike wheel drives an electric motor with converts the mechanical energy into electric energy. The DC power is conducted through a diode and through a current sensor. Then the different cables are connected to the supercapacitor. This is the common point. From the supercapacitor we draw the power for the solar inverter that converts the fluctuating DC power to regular AC power. We monitor the power before the common point.

}}
{{ {{tntn|Tuto Step}}
|Step_Title=Chose your buffer
|Step_Content=You can chose between different buffering systems, an battery, a supercapacitor or a flywheel.

We chose a supercapacitor. A supercapacitor is an electronic component able to hold a charge. It can be used in the same function as batteries with the following differences :

+ a capacitor is easier to recycle than most batteries (references will follow).

+ a capacitor can provide and absorb a higher peak power.

– the voltage varies with the charging state of the capacitor (it needs an additional converter to provide the voltage of the system)

– the energy by weight capacity is less interesting than with batteries.

– the cost by energy is higher.

– the lifetime is quasi infinite (1M cycles).

The energy storage of a supercapacitor :

energy = 1/2 * C * voltage difference^2

http://www.engineeringtoolbox.com/capacitors-energy-power-d_1389.html

ex = 1/2 * 500F * (16-12)^2 = 4000J = 1.11Wh = 1 cyclist for 1min20sec

}}
{{ {{tntn|Tuto Step}}
|Step_Title=(if you chose a battery)
|Step_Content=''First remark : if you can avoid using a battery and work with the people pedal power in stead, this is considerably more interesting for the environment''

– car batteries a heavy compared with the energy they can store, they are designed for giving high current.

– deep cycle / cyclic / boat batteries can contain more energy because of the internal structure of the battery technology, allowing a deep discharge.

input : user power (ex sound system of 900W peak)

input : time of autonomy (ex one hour before charging)

input : voltage of the system (ex 12V)

energy need = user power * time of autonomy (ex = 900Wh for the sound system)

''checking the battery parameters''

– Gel and Absorbent Glass Mat (AGM) types of VRLA can be mounted in any orientation, but need to be ventilated.

– the depth of discharge (DOD) of a battery determines the capacity and the number of cycles, 60% is a good value for AGM batteries (check DOD documentation).

– the current of discharging lowers the voltage output, the higher the discharge current, the lower the voltage and the lower the capacity.

battery voltage at the DOD > voltage of the system (ex 6 cel Li-ion doesn’t work, ex when discharging in 3h (0,3C), after 3h the battery voltage drops to 11V)

charge need (Ah) = energy need / voltage / depth of discharge (ex = 900Wh / 12V / 60% = 125Ah)
