A hackable puzzle-solving kit with 16 logical and timing puzzles.
Gaming
Kits
Raspberry Pi

A puzzle-solving kit decorated with alchemical symbols and sigils in gold. A total of 16 puzzles to solve some of which are timing based while others require logical thinking.

There are six RGB LEDs spaced around the perimeter with three rotary encoders and three pushbuttons in the middle. A circular LCD screen in the centre displays instructions and a piezo speaker provides audio feedback. A Raspberry Pi Pico single-board computer powers the board.

A typical puzzle involves manipulating the rotary controls and buttons to match a target pattern of colours on the LEDs.

The firmware is written in MicroPython to make it easier to modify and extend.

The kit includes some surface-mount components so isn't really suitable for absolute beginners but the (mostly passive) SMD components are not too difficult to hand solder.

Powered by 3 AAA batteries (not rechargeables) or via a micro-USB cable (with a small modification - the orange wire in the image above). Batteries not supplied.

What's included - printed circuit board, pre-programmed Pico, LEDs, LCD display with header, pushbuttons and slide switch, rotary encoders and knobs, piezo, battery holders, resistors and capacitors. In fact all the components you need to build this kit.
