Retro Psion 5MX PDA Tweets Via Raspberry Pi Zero

This project adds a whole new element to revitalizing retro hardware with a Raspberry Pi.

If you’re looking for a fun way to tweet with a Raspberry Pi and have an affinity for old-school hardware, look no further than this clever Psion 5MX-driven Pi project created by maker and developer Kian Ryan. Using a serial connection and a little bit of tinkering, he’s managed to operate a Raspberry Pi Zero and send tweets to Twitter using the classic Psion 5MX PDA from the late 1990s.

It doesn’t take much power to operate both the Psion 5MX or the Pi Zero, with the former running for quite a while using nothing more than a couple of AA batteries. Putting the two together just makes sense as a low-power system with a modern twist and great potential for portability.

Ryan has a history of working with microelectronics and 3D printing as evident by his catalog of past projects on his website. These projects are backed up with his experience as a freelance software engineer and consultant. Examples of his endeavors include things like this glowing skull printed with recycled filament and this touch-operated night light.
