A pocket anagram game designed to help improve your word skills.

On the Technoblogy website, David Johnson-Davies designed an anagram game called Conundrometer to help his son improve his anagram solving skills. This seemed like a great project to upgrade with a PCB and a 3D printed case. I also changed the circuit to use a more modern microprocessor.

The circuit is designed around a ATtiny3216 microprocessor. This 20pin device has 32K Flash memory and 2K Static memory which happens to be the same sizes as the ATmega328 used by the Arduino UNO. Unlike the ATmega328 microprocessor, the ATtiny3216 can run with a 1MHz clock. This means it uses at lot less power while it is running and while it is in sleep mode thus allowing the battery to last longer.”
