The coin pusher

Posted on by Bart

When the fair is in town, we always pay a visit to the coin pushers. You know, those machines where you buy a bucket of coins, you throw them in the slots, and they gently push the coins & prices closer and closer until they drop.

But actually, I’m not a big fan of those games. Too repetitive and too much randomness. So I come along because my wife & kids like it, but they do most of the coin throwing.

But last time – while watching – I was wondering whether I could build a coin pusher myself.

So I took my Lego Mindstorms (and a couple of extra boxes) and started building…

The result

The DETAILS

The program

The programming consists of 4 parts

  • The motor, which is rotating back and forth
  • The sounds, played randomly
  • The display, with a fixed text
  • The lights, flashing different colors

If you are familiar with Lord of the Rings, then you have probably already heard of Gandalf the Grey, Saruman the White, or maybe even Radagast the Brown. And perhaps you even read somewhere that there are even two more wizards, of which even Gandalf doesn’t remember the name anymore. But did you know that there is a sixth wizard called Bart (referred to as Baruman by some)? While the other wizards were fighting wars over a single ring, Bart was collecting hundreds of rings playing Sonic the Hedgehog. Furthermore, Bart used his Palantir to watch Star Wars instead of challenging Sauron. And finally he visited the libraries to study ancient lore, mostly found in comic books. Now however, Bart has grown up, married a sorceress, and they have two sweet little hobbits. You can follow Bart’s adventures on geekstuff.blog.
