Yes, it's ... Useless! It's a clever electromechanical box that turns itself off after you've turned it on.

You build it, you turn it on, and ...it has other ideas. A finger extends, and turns itself off just as quickly as you turn it on. Weird and wonderful, it's a physical description of many aspects of life (how's that for the beginning of an artsy interpretation?).

Kits can be occasionally frustrating, but be assured that with our Solarbotics full satisfaction warranty, you have complete confidence that if your Useless Machines starts ... acting useful?... or otherwise, we'll take care of the problem. Broken or lost parts? No problem. Contact us for any issue you might have.

The Useless Machine Kit requires assembly, and you must have your own soldering equipment, batteries, and phillips screwdriver.

Each kit includes:
1 x 39300 Black acrylic "Useless Box" construction set
1 x Motor set (GM3 Motor and Accessory Wheel)
1 x Double-pole, double-throw power switch
1 x Single-pole, double-throw retract limit switch
1 x 4-conductor ribbon wire
1 x 2xAA battery pack
1 x Double-sided sticky tape
4 x Miniature hinges
2 x #4 x 1/2" Motor-mounting screws
5 x #2-32 x 3/8" Limit switch / finger mounting screws
1 x #2 x 1/4" and #2 Washer set for accessory wheel
22 x #4 x 3/8" Bolts and #4 nut sets
16 x #2 x 1/4" Hinge-mounting screws
4 x "Little Rubber Feet" to protect your Useless Box from abrasive counter tops!

Sure it's useless... but it keeps your itchy switch-flippin' fingers busy!

Customer Reviews

  1. Review by Robert verified purchaser

    How do you rate something that's meant to be useless? It succeeds admirably in this objective. Just a bit of fun. (Posted on 20/04/2016)

  2. Review by Lacey - So useless.. verified purchaser

    The useless box had easy assembly, minus the 8 screws use to hold the two hinges in place. So I used an electric screw driver I use for PC repairs.

    Other than that, no pieces broke while assembling, soldering was easy, instructions clear, and was fun to make. (Posted on 21/10/2015)
