The Useless Box is now sporting 4 metal hinges to hold the lids in place instead of our previously tacky tape. Yes, it's ... Useless! Designed as featured over at Makezine.com. It's a clever electromechanical box that turns itself off after you've turned it on. This is now a full kit, 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) 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 4 x Rubber Feet 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! Documentation Manual v.1.2 Useless machine box lasering plans Useless Machine Instructions v.1.1
