I could not believe the price myself, I paid 25 Dirhams in a super market which is about 6.80 dollars, but thats after shipping, storage, shelf stacking, etc etc etc.
How you can dig something out of the ground for 2.68 USD never mind turn it into something is beyond me.
On the upside why would you build a keyboard interface when there are ready made ones with an additional 30 something utility buttons for about 5 dollars.
I will post it in barsport as thats the direction this might go.
