  • Looking forward to this one! I'm guessing that with the programmable coin acceptor, different prices will furnish different insults, from the mild and mundane, to the definitely NSFW Kevin Kline gem. I may replace the arcade button with the Big Dome Button, because my co-workers can't resist the lure of the big red button, and i don't mind taking a little of their money.

    I am super pumped about this! Just placed my order. I manage three coin op laundromats. I've always wanted to build something from scratch that's coin operated! This will be a great starting point, I think. Not that I'll offer insults for sale to customers...

    With a adjustment of the printouts it would make a good "Machine of Death"

    • I just realized that I've had a copy of that sitting in my to-read pile for approximately as long as I've worked at SparkFun.

    Didn't intend to double post - how do I delete??

    Anyway here's a link to a coin-operated installation I did at a local bar a few years back :

    I made $110 in quarters - who says there's no money in art?!

    Was this inspired by my advice machine (, or just a pleasant coincidence?

      Coincidence. I've been meaning to make this for a very long time, but never got around to it until I had a motivating force.

    Will the provided code for this project work? The code for the last sparkfun live did not work without modification. It took me quite a few hours to get the code fixed when i was doing my project.

      Sorry about that. Yes, it will definitely work; we've got one up and running in the break room now.

      The hardest part of the project is teaching the coin acceptor what each coin looks like. It wants you to insert 20 coins of each denomination of a different year; I've done it with fewer than 20, but the more you put in, the better it works. Best to have a handful of change on hand!

  • Can I get the code? I would like to take a peek!

    • SFUptownMaker / about 10 years ago / 1

      The code is up!

      Not yet...I'm still working on the wiring diagram for it. I've got to make a Fritzing part for the coin acceptor.

      It will be live at least a couple of days before the event, along with instructions for configuring the various parts used in the project. I'll update this blog post when it goes live; otherwise, you can keep an eye on our GitHub page to see when the repository goes live. This link will take you to it, once I've created it.
