Supercapacitor solar harvesting from BPW34

Micro size night lamp, pulse harverster

Similar projects worth following

- 4x BPW34 photodiodes aka solar cell
(plastic diodes, resistant to damage against glass solar cell)

- Up to 10F supercapacior
(You can use bigger capacity but 10F is optimal for charge in one sunny day)

- 4 hours operation in night depends on intensity

- Auto night on

- step up converter effective use all stored energy, discharge scap until 0.3V !!!!!!

TWO operation modes ...

1. Night mode - output is activated in night
2.Pulse mode - output is activated after capacitor is charged to startup voltage

Enjoy this project?
