Intro: Micro USB Upgrade for Standard Flash Drive
Upgrade your old not cool and not mobile friendly flash drive to micro usb monster. :D
Step 1: Tools
Step 2: Opening
Step 3: Wiring, Soldering and Closing
This was easy, just grab some thin wires and solder them at the usb pinout, better would be solder them directly on chip but i was too lazy for that.
Edit: Added usb wiring, if you have cable with some weird colors use multimeter. ;)
Step 4: Finish
Now just close it, add some hot glue and use heat shrink tube for finalize.
