In all likelihood there is a keyboard within a few feet of you. Inside that keyboard there probably is a circuit sheet that makes for a surprisingly durable and thin material for making a wallet.

Any mention of this project must provide a link to www.zieak.com with credit to Ryan McFarland.

Why? In taking apart electronics i find uses for most of the parts. Things which can not be reused go into scrap piles for recycling. But these sheets couldn't be easily reused and probably can not be recycled. I tried using overhead transparency sheets that had been printed on for a customized clear wallet pattern but the sheets mark when folded or creased. These circuit sheets are extremely durable.

You'll need:
A desktop computer keyboard (for the circuit sheet and a metal piece as a straight edge)
A screwdriver to open the keyboard
A ruler or tape measure
A cutting board or cutting mat
A razor knife
Sharp scissors
A roll of clear packing tape

The fine folks at HowCast have made a video from my Instructable...

All of the keyboards i have opened have used a series of small Phillips screws to secure the top and bottom pieces. Remove them and open the keyboard. There probably is a sheet of metal secured with more screws. Remove the screws and set the sheet of metal aside to use as a straight edge during your cutting. Next is the circuit sheet which should be quite easy to remove.
