It's cool to see Chris Staecker's channel getting some love, he brings a a kind of joy I miss from the old internet. I know it's still around, but it certainly feels more difficult to find and suppressed in many ways.

I think the algorithm recommended Chris to me because of his topology videos, and from there I watched all his "old computing devices" stuff. Something about the Boston accent, the dry humor, and the occasional audio jump-cut make his stuff quite funny.

Reproductions are still produced, see the wikipedia page.

I still have my Digi-Comp I, as well as Dr. Nim and Think-a-Dot.

I bought one of these from Edmund Scientific when I was a kid. I wasn't able to figure out how it worked. I've thought about it occasionally over the years. Enjoyed the video

I had a CARDIAC when I was young.

Still got it? Would be pretty neat to bust out of the attic ..

This reminds me, a CNC wire bender is on my list.

Jörg's automation of the machine is truly fun :) The mechanics of the machine are really clunky and giving it an external clock made it function so much more smoothly iirc.

I had one! One of my favorite possessions in elementary school. It came with a nice booklet introducing the theory. Because I studied that booklet, I was probably the only brat in my 2nd grade who knew about number bases. I entertained myself by converting decimal numbers into binary.

Wait til you see the DigiComp II! It has flip-flops driven by marbles and gravity. Truly astounding.

I learned binary computing from that machine.

It looks amazing! Thanks for mentioning it!

Wow. didn't know mechanical computers could be so simple.

Really cool! Will we ever construct Babbage's Analytical Engine?

There was a (stalled) recent attempt: https://blog.plan28.org/?m=1
