This is really the opposite version of the "Byte Box" (Gallery page 7), but it would be a bit silly to call it the "Un-Byte Box", and since it uses dials to help get it open, that's the name.

Three dials, each numbered from 0 to 9, and each one has to be pointed to a particular number to allow the box to open.

You could work through the 1000 combinations and find the right one, but the answer is showing on the top, as a line of binary code.

Work out this code, and you'll get the three correct numbers.

Very easy to make, only six discs to cut, and you can make your own combination.

Size of this box is 6" (15.3 cm) by 3-1/2" (8.9 cm) by 2-3/4" (7 cm), if cut from 1/8"

(3 mm) wood, but the plans are T-Plans, so you can make this at any size.

A tall box, with a pendulum on each side, a little slider at the bottom of each side, and four sliders on the lid.

If you tilt the box, the pendulums will all swing to and fro. The top sliders won't move, but the small sliders on each face can move upwards.

If all the pendulums are free to swing, the lid cannot be opened, but each of the little sliders will lock it's own pendulum. The question is, how many pendulums need to be locked so that the lid can be opened-one, two, three or all of them?

To make it worse, the sliders on the lid can only be moved in a certain order, and each is locked in place by a pendulum. Move the four lid sliders, and the lid will lift off.

Size of this box is 4" (10.2 cm) by 4" (10.2 cm) by 6" (15.3 cm) if cut from 1/8" (3 mm) wood, but the plans are T-Plans, so you can make this at any size.
