Cordwood Puzzle One

by Boldport

Experience the thrill of 1960s PCB assembly with the Cordwood Puzzle One soldering kit from Boldport!

In the 1950s and 1960s inventive engineers saved space by using the 'cordwood' assembly, where components were sandwiched in between two circuit boards. This construction became less useful with reduced component sizes, PCB manufacturing advancements, more compact integration, and surface mount technology, but it's still a lovely piece of history. Combining both old and new, the Cordwood Puzzle is a tribute to this construction and to the engineers who came up with it.

The puzzle is to correctly assemble the circuit with the components at hand. Once completed, all of the LEDs light up when power is applied. When connected to a controller board, each LED can be individually controlled.

Unfortunately(!), all the comprehensive assembly guides were mysteriously missing from the kits.

Note: requires through-hole soldering!
