Bitcoin vanityaddress keychain

Final product

I used OCLVanitygen to generate the vanity address. It starts with my dad's first initial and last name (case sensitive). I was lucky in that it only took about 6 hours to complete. Check on the comments section for details of how I got the app to work on my Radeon HD6970

I carefully wrote down the private key and then used a free online QR code generator to turn the address into a QR code. I used Photoshop to increase the resolution (manually selecting the option to prevent the scaling from blurring the edges) and then imported it into cambam selecting a depth of .5mm.

I had a .049" carbide end mill to work with, and with that input, cambam created these tool paths.

I started with a piece of 2"x1/8" aluminum bar stock, cut a section, and milled down all the surfaces to make it square.

Here's the mill at work

Another progress shot. It was really amusing watching then order in which the algorithm chose to cut the grooves.

It took 10 passes in each section, so I was only removing 50 micrometers of material with each pass. I broke my first bit when I had it remove too much too fast.

Here's the finished milled product. It took a little over two hours to finish milling.

I got a can of flat black spray paint and coated the whole thing.

Here it is after a second coat.

I started with 80 grit sandpaper to remove the paint on the elevated sections. I also removed the paint on the back and sides.

Here it is after a once-over with 400 grit paper.

And I drilled a hole for the keychain. I'm considering leaving it like this, but I may do a simple layer of clear-coat to protect it.
