Solarbotics Useless Box Kit
Ever seen a Useless Box?
It turns itself off when you turn it on! Here's a kit to build your own! It's not quite totally useless, especially if you like flipping switches.
This is now a full kit, complete with Solarbotics satisfaction warranty, but you will have to assemble it (requires some soldering), supplying your own soldering gear, batteries, and screwdriver.
Each kit includes:
1 x 39300 Black acrylic "Useless Box" construction set (with nut/bolt hardware) with "crack" warranty.
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!
