Instructables is currently holding a USB contest. Having never done a instructable I felt it was time I gave something, no matter how meager, back to the community. I haven’t had the time to invest in a producing a solid instructable, but I do have my prototype built and as far as I can tell, it works! I will however be missing the contest deadline, and that I have excepted so that a proper contribution can be made.
I am basing my regulation circuit off a LM317 3 Terminal regulator. It may be a very simple circuit but I haven’t come across it in this application. In fact the circuit is taken from the data sheet.
I will be providing the full plans on how to make your very own USB Variable Power Supply. Please check back regulary if this project interests you.
