Looking to for a simple DIY project for a school report or class event, this USB charger is it!  Or if you’re just looking to try your hand with some simple electronic wiring to see if you have what it takes. Well, using some off-the-shelf times, a battery and the simple schematics below you can have a great USB charge for just about any USB product. The full tutorial is at Instructables, and I’ve also seen a couple good comments in their thread, like:
UPDATE: the module that this poster mentioned is available via the ti website as a free sample. you can click the link the poster provides which will directly place you at the right module. click sample or buy and register a myti account. note you MUST provide a business name(i use my last name combined with the hobby im into which is legal by law and you do not need a verified business with the government either) you must also provide a url so just sign up for a free website at or similar and activate the account. you do not need to create a webpage. than continue with the sample checkout. it will ask for end user info. click same as button unless youd like it sent elsewhere, check out and youll get the fedex confirmation email next day or same day if its between 9-5.
