This semi-retro technique to build DIY computer was inspired by this amazing piece of art ("The Cardboard Computer"):
I decided to implement my own very similar approach for "Germanium Calculus" project - namely The Corkboard Computer concept ;)
I started with these things that I stumbled upon in the local grocery store:
As you can see it's 125 yellowish tacks for $1.99 or about 1.6 cent per point!
Then I bought these cork tiles in another store (4 tiles 12''x12'' for $7.49):
Then I successfully tried to solder something to it :)
For now I think it's the best way to finally build my "Germanium Calculus"...
