Useless Machine Bundle

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!
