Preview of Pendulum letter scale
By Krypto
Complexity
Medium
MAIN PURPOSE: Weigh letters without an electronic scale
Hang the scale on a drawing pin through the top hole, clip a letter to the arm with a bulldog clip and read the swing against a plumb thread: up to 100 g, enough for every letter rate. Calibrate the marks once with coins (a 1p weighs 3.56 g).

Lay an A4 letter face down with its top edge against the lip, fold the bottom up over the board edge, turn it over and fold the top down: the board is exactly 99 mm deep, so the thirds come out even and the letter drops cleanly into a DL envelope.
