Hi Monte,

Good post.

You and Victor should get together. If you take the TEG and just put it in your bike helmet and run a small water pump with some cooling fins on your back, the helmet or on the bike, you should be able to exploit your used calories during a bike ride to power the bike light and the cooling system.

I also agree with the pulse mode for the LED. You can drive the LED fast enough that the perceived brightness will be more than you could output with a constant current source.

Could be a neat side project.

Just a thought,

DAB

Try to add a resistor to this LED to regulate the current. I believe you can get the LED to light continuously and not only blink. The STK with the temperature program uses 2 mA. With the warm hand you can get even more power.
