The Optimus STA-300 is a surprisingly great sounding amplifier. I had one of these new back in the mid 90s and recently picked one up from an auction site.

The Pioneer SX-626 was an early 70s HiFi receiver which had that classic wood case and silver faceplate. This was my first receiver which I had when I was a kid, and I recently restored one.
The M5Stack Cardputer is an inexpensive, functional, and highly portable computer. I was able to use it to connect to my HF TNC via SSH.
Adding AirPlay 2 support to existing amplifiers and receivers is simple and cost effective. Simply add an AirPort Express (2nd Gen) to an audio input and instantly stream to your older equipment.
I updated one of my (tr)uSDX transceivers to the mainboard revision 1.2 to see if it fixed the “howling” issue.
I have had some success refilling vintage plotter pens for the Casio, Sharp, and Radio Shack printer plotters. After quite a few trials and errors, I might have finally solved the refill challenge.
I adapted the PB-770 maze program for the PB-1000 and created three types of printouts for the randomly generated mazes.
The Casio PB-770 was quite an impressive model given the release date. With a multi-line display and memory expansion options, this model was certainly a competitor to the Sharp offerings of the time.
I found a Casio PB-1000 and an MD-100 on an auction site. I have spent a few months with this pocket computer and it has become one of my favourites.
After hearing quite a bit about Meshtastic, I picked up a few different inexpensive devices to experiment with and see how well they work for off-grid texting.
