HOW IT WORKS

DESIGN

The external dimensions of the TPB are: 200mm x 100mm x 40mm (length x width x height). The dimensions of the chamber inside are: 160mm x 70mm x 18mm (length x width x height), whereby that is padded with cloths to protect the contents and prevent them from slipping.

There are connectors along the long sides to prevent the shells from moving laterally and magnets are attached in the corners to keep the TPB closed.

ELECTRICS

The batteries with the corresponding contacts are slightly offset relative to the longitudinal axis so that, depending on how the shells are rotated in relation to each other, they either close the circuit and thus cause the LEDs to light up or leave the circuit open to conserve the batteries.

Sounds good? Maybe you want to take a look at the used PARTS and the BUILDING INSTRUCTIONS.
