When Iron Man came out, it certainly had an influence on the maker scene - definitely on Dave. He has decided to finally 3D print the files for a Mark 2/3 helmet found on the internet and upgrade the print with not one but two self-made head-up displays! He talks us through the problems he encountered setting up the displays to work and finally install the lenses and displays into the faceplate.
