Introduction: Lakerol USB Charger From Old Nokia Batteries

Hi all!
This is my version of the Portable USB Charger by "slipknot rules". Original found at

Check his page for schematics, partslist and some good discussion in the comments.

Check my pictures and the comments in them for what i learnt while doing my version...

Btw, if you have all the parts except the 7805 regulator you can find one in an Nintendo 8-bit. Thats how my project started... :-)

And of course I am not liable for any damage that may occur to your devices from using this project.
Li-ion batteries can be potentially dangerous. Handle them with care and NEVER short-circuit.
