Hey Ben,
I often see you use tact switches for game controllers. I find these switches too heavy to use in controllers. A few weeks ago I disassembled an old Gameboy Advance and to my surprise I found rubber dome tact switches used for the shoulder buttons. A short search later I found these switches sold online.
Just a quick tech tip...
I am also curious what material it is you used for the Hand Soldered Atari 2600. That silver looking sheet which becomes black when you laser cut it? I mean the front facing panel. It looks awesome.
I would love it if you talked more often about the materials you use for your builds.
Keep up the good work. I love your show!
Would like to see more T-shirts giveaways though...
