The Cardboard Computer

[dlevere]

60 year old Mark Nesselhaus likes to learn new things and he’s never worked with hardware at the gate level. So he’s building himself a 4-bit Computer, using only Diode Transistor Logic.

You know he’s old school when he calls his multi meter an “analog VOM”!

It kind of makes me think of a simpler and less technical thing of when I was about 13 and my friend used a box he had from a new pair of shoes, and turned the box into a decent bass speaker.
