How to make a Thermoelectric Flashlight

Описание: This is a tutorial on how to make a thermoelectric flashlight. You'll never need to worry about having batteries for your flashlight again.

FAQ:
1. Q: Where do I connected the red and black wires from a thermoelectric module?
A: The red wire is connected to VCC on the circuit layout at 10:20 in the video.
2. Q: My MOSFETs keep dying. How can I prevent that?
A: Avoid powering the circuit without an LED or load. If the input voltage is too high (~500mV) under no load conditions, the output voltage (MOSFET Vds) might go too and damage the MOSFET.
