Description

I would like to build a USB Power supply that I can carry around everywhere, to use wherever needed. It has to cope with up to ~10w @ 1 -> 12v.

Goal

  • Make it safe, with short circuit & overload protection
  • It cannot be any bigger than a credit card, and not very tall either
  • Settable to 0.1v and 10ma, and fairly accurate
  • Goes all the way from 1v to 12v, up to 10w in total

Obstacle

  • I have almost no electronic skillz
  • It has to be safe, with beefy diodes protecting my computer

Components

I think I will base my design on this and this

Schedule

None really... preferably 1 or 2 months from start to finish though
