The Most Useless Machine. Ever.

A few weeks ago I came across a video on Tumblr entitled “The Most Useless Machine Ever” – as soon as I saw it I knew I had to have one, and thankfully the guy who posted the video, “SaskView” also posted an Instructables page with instructions for the circuit and assembly. This struck me as a perfect basic electronics project to take on with my son, Oliver.

The finished product

Assembly & Tweaks

Assembly took place over a couple of weekends as I got my rusty soldering skills back in shape and finally learned how to read circuit diagrams properly. In the end, we fell back to a simplified circuit (that someone had posted in the comments of the Instructable) that turned it from a relatively complex circuit (for my current skill level) to a basic two-switch, one-motor affair. We did have to lobotomize the servo motor so it was free spinning & wired directly to power (basically turning it into a plain old motor”) but I don’t plan on pulling this apart so I wasn’t too worried about it.

It was a fun little project and surprisingly, it never gets old, even a week later I can’t help but flick the switch whenever I walk by it :)

    I love your take on the design of this. The old box and the furry thing that jumps out make this thing kind of awesome. I think I might have to make one now.
