Thank you for following my project https://hackaday.io/project/159139-tiny-solar-energy-module-tsem. Did you know I am selling two TSEM derived boards? One that stores it's energy in a Li-ion battery and another that uses supercapacitors for storage. https://www.tindie.com/products/jaspersikken/solar-harvesting-into-li-ion-battery/ and https://www.tindie.com/products/jaspersikken/solar-harvesting-into-supercapacitors/

Are you sure? yes | no
