I bought one of these keyring photo viewer, it was only a tenner so I thought "yeah why not, might be able to hack that into something cool".
So it turns up and the first thing I do with it? Pull it apart and stick it in a wrist warmer :)
Step 1: Pull It Apart
First step as always is to pull it apart. There are 2 small screws holding the back on, remove those then prise the case apart.
There are now 2 more screws on the circuit board which need undoing. Undo (or in my case, trash with nail clippers) them and take the board out.
Step 2: Prepare the Wrist Warmer
Cut a small hole for the screen, this stuff seems to stretch well, so dont worry about fitting it all in.
Step 3: Check It Still Works!
Check that the thing still works, make sure that the lil ribbon cable is connected. This cable will need strengthening with some thin plastic as its very fragile and will get bent a fair bit during use.
Also glue a flat piece of plastic to the back of the screen and pierce some holes around the edges. These will be used to sew the screen in place later.
Also glue the battery to the back of the screen
Step 4: Cram It In
Cram it in the hole, push it though so the screen is in place, then sew through the holes in the plastic to secure it.
Use fabric glue to glue the edges of the screen and frame it nicely with the fabric.
Step 5: Turn It On!
Version 2 will have some proper fabric buttons sewn in (should make it easier to operate) and a proper hole sewn in for the USB socket
Also plan to enhance the battery life too, at the moment it lasts about 30 minutes on the slideshow mode, which is a bit pants really.
