Wasn't able to make it work. I'm sorry but I know there is an available piezoharvester module i found on youtube. Its a small circuit that regulates piezo electricity to bearable voltage and currents.
was it really able to charge your battery pack? Were the voltage and current enough? I'm trying to do the same project but I can't charge my powerbank with a 5v, 1a requirement. My piezosystem produces an average of 12volts. The piezosystem is made of 6 piezos in parallel. I tried connecting it to an L7805 ic to get 5v and 1a current but to no avail. Still doesn't work. Really Need help for a school project. A reply asap will be much appreciated
I've tried directly wiring the rectified piezosystem to a rechargeable battery pack, and damn it broke my batteries. For the battery pack, I made it myself. I got two 3.7v phone batteries connected in series. How do you not destroy your batteries and charge them?
how can you tweak this cicruit in order to produce lesser current. I need 5v and 400 ma output. Should I get another capacitor with different capcitance, if so what?
did it really charge the power bank's battery? i doubt it...I'm trying to do a similar project
This is not your original idea. Just saying
