Sit this on the coffee table and you will sure have a conversation starter with any geek. :)Â Next step is to make it into a working keyboard, now that would be impressive! Via:
We are following along with the build of the Electric Dune Buggy Conversion that Frank from TheWorkshop.ca has been working on. We featured the second part in the build back in January.
