Here is the progress so far (Images Hosted by Doom56.com
I brought multiple power banks

Took them apart to see what i can use

The Raspberry Pi 3 (Model B) Turned up but needs slimming

Removed the Connectors (USB, Network, Camera, ect)

Marked the link for further slimming

First power bank battery is a bit too big

Found the right ones so started to remove plastic

In with the new batteries (2x 2000mAh)

The battery cover would not shut so had to file some edges down

Made a USB socket and added some Epoxy to give it some strength

soldered a tactile switch to a board, Then filed it down to make it smaller

Ripped an old game cart apart and started filing them down to make a frame cover, then dab of black hot glue was applied

added a clear window so you can still the pi and may add a ligh to shine too (if i have room)

Super glued in the tact switch to the power button and added a dab of glue to stop the switch sliding

little messy but thats the way i do my projects (kinda my signature lol)
