Teaser Video: Energy Harvesting Ring Project

Just got the latest revision of my energy harvesting ring PCB and soldered it together. Here is a short teaser video showing it light up. You don’t see much! I stuck my hand outside due to the fact that the heat of my house is too warm to get it lighting without air movement. Its still requires around 40mV to get it going but will continue to blink slowly at around 20mV. I feel as though with an actual TEG module such as the eTEG HV56┬áit will be on much more frequently. Right now I’m only using a small peltier module not made for generating. I’m still very satisfied with my results. A couple pictures after the Jump!
