Today’s project was Cordwood Puzzle 1, a secret santa present from a good mate.

Just hard enough to complete without cheating! (although I should have left the leads longer to keep things symmetrical).

Oh, and Happy New Year all!

A squared note book with some large resistors and a narrow PCB on the top half of page. There are some notes and circuit diagrams on the bottom half.

A PCB in a clamp. There are three MOSFETs in a row along the top of the board, and a 6 pin header close to the camera.

The same PCB from the side. There’s a large LED on the bottom of the board and two resistors on the top. The resistors are connected with crocodile clips (to the positive supply rail which is not shown).

The completed puzzle: two PCBs, side-on, with 6 LEDs, 6 resistors on a plane parallel with the camera and another 6 behind. There are also standoffs connecting the boards and some jumpers running between them.
