Are your days long on confidence and short on insults? Do you find that your morale is just too high? Well we've got the solution to your self-assurance problem: Join us on Tuesday, March 11, at 3:00 p.m. MT for the next edition of SparkFun Live, where engineer Mike Hord will help you build the "HaterMatic," a coin-operated insult generator of delightfully ego-crushing proportions.



If you'd like to join in the fun, the wishlist of parts for this project can be found here. So gear up, and we'll see you scruffy-looking nerf herders on March 11.

  • 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"
    See http://en.wikipedia.org/wiki/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.

  • Hey, the opening screen gets me to "dispense" an insult: "Are you not wise enough to realize when the change to Daylight Savings[sic] Time starts?" The "tease" on the screen says 3PM Mountain Standard Time... and for folks in states that are wise enough to save time by not having to change our clocks twice a year, that makes a difference!

  • 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 : http://www.noisemantra.com/CoinOp/coinop.htm

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

  • Was this inspired by my advice machine (http://blog.notdot.net/2012/09/Penny-for-your-thoughts), 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.

  • Hmmm... the thought occurs to me to build one of these and put it out at the next "mini-convention" with proceeds going to the charitable foundation... but I'd have to put it in something more rugged than the red box of the prototype.

    I trust that the code will be easily modifiable. I might want to print something like "For your donation of $0.25 you are rewarded with the following Hater-matic insult:"

    Knowing the group, though, the Foundation would likely get more if I were to just donate the cost of the parts... though that wouldn't be nearly as much fun.

    • As a follow-up, I ran the idea past my girlfriend (whom I met at the national convention a couple of years ago), and was surprised by her very positive response. (She has had a very negative response to my plans for "wearable electronics".) Since I saved several hundred dollars on a major purchase (a new fridge) yesterday, I guess it's gonna be within the budget.

  • 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!

  • Chewbacca: Wookiee chuckle

    Han Solo: "What are you laughing at fuzz-ball?"

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

    • 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.
