The Cardboard Computer - IO is my name

Back to overview

My goal is a 4-bit CPU using recycled cardboard substrate and Diode Transistor Logic. This is an educational platform for me.

love lt!

Check out my cardboard computer on myYouTube channel gort59

Your Minivac601 is great :-) I wanted to do a relay computer but ended up with a large stock of transistors so went that route :-) These projects keep us both out of trouble Lol

I really needed something like that when I was young :) how difficult to solder components to those caps? Do you use regular solder and flux? Any special tricks?

Hello Shaos, nothing special, just 60/40 rosin core. the fasteners take the solder very well. Just have to heat sink the transistor and diode leads while soldering.

Great! I've decided to do something very similar, but with "Goldtone Thumb Tacks" - see here https://hackaday.io/project/10724-germanium-calculus

I love your calculator project idea :-)   I have used silver and gold tone and the gold took the solder a bit better. Thank you for the link.

Wow, ok. So it's just a larger Cardboard NAND gate. I just like how it's cardboard, makes everything better.

Good evening coletonn, not sure if better but sure is cheaper. Looks strange but then so am I for trying this project. Have learned from a lot of web sites so not inventing anything new but it is all new for me.

I should start calling my cardboard cutouts VLC's or very large chips :-)
