Those look beautiful! Supersized ones would make great gnomes.
Beautiful system, your schematics look great.All the best,Danno
Great project, and an amazing story. You definitely deserved all my votes. How fine is the gearing for focusing? All the best,Danno
Nice project. How does the FPV impact the quadcopter's battery life?All the best,Danno

Good morning,They are also called "Electrical Nuts" or 'Twist Type" connectors.All the best,Danno
A solar charge controller will definitely work. Just check the voltage and amperage ratings.All the best,Danno
Thermoelectric solar is a very practical application of thermoelectric generators.Most thermoelectric solar systems use black pipes filled with water and glycol to absorb the heat. This allows for a higher temperature difference on Peltier Plates and therefore more power. All the best,Danno
It sound slike you may have burnt out a motor controller on the main board. You can always buy a new mini quadcopter and keep this one for spare parts, or buy a new control board. All the best,Danno
You should check the power draw of your motors. I upgraded my quadcopter to more efficient motors (same electrical draw fro more rotational power). If you selected motors which draw more power, you may be pulling more current than the control board can supply. You can either upgrade your control board or upgrade to more efficient motors.All the best,Danno
Good morning,I used a 1050mAh 3.7v LiPo phone battery, that I salvaged it off of some old electronics.All the best.
Did you change the motor and the wires? Or just the motor?If you have a continuity tester I would test each wire and across the motor (to check for breaks and shorts). The wires on the motors commonly break is crashes. Have a great day!
Did the circuit board fully break or did the contacts (leads) just separate from the board?

Great point about the wiring diagram, I will replace it with a true diagram.Wiring the fan in parallel with the peltiers would help to increase efficiency. I will add a note to the instructable.Have a great day!
This would restrict the efficiency of the primary peltier, resulting in less cooling. The secondary peltier would function as a generator.Due to the laws of thermodynamics and thermal loss of the system would have a lot of "wasted" energy. It would be far more efficient to limit the power to the primary peltier to reduce the amount of cooling and not use a secondary.It is common to stack different sized peltiers (small to large) to pump heat from a small source (ie CPU) to a large heat sink, but all of the pelters are powered. Have a great day!
I apologize for the late response, I did not notice your comment. This setup will work, but peltier A will reduce the generator's efficiency, because it will insulate the cold side of peltier B. You could use a temperature switch which would power the generating peltier B to pump away excessive heat to avoid melting the peltier module. The use of a switch would cause periods where the generator will cease to generate (and will consume power) but it will generate power and cool itself much more efficiently.Have a great day!
Water cooling can most certainly be used (at the end of the above video I used snow as a coolant). Since water is not very thermally conductive the cold side of the peltier could be well over 100C, increasing the surface area of the metal touching the water can help if you run into thermal issues. The best practice is to keep a careful watch with a thermometer until you know the cooling capacity of your system. The maximum temperature of the generator is mostly limited by the fail temperature of the peltier plates you have purchased. The hottest I have heard of were around 800C hot side. Have a great day!
