My current lockdown project is finally starting to look like an actual thing. It started out as a simple adaptor I was making for a friend to passively run some case LEDs from the floppy power connector. But it grew arms and legs, and has become a clockport-mounted board that can control addressable RGB LED strips, read multiple temperature sensors, control a case fan's speed, and react to various events, such as floppy or hard drive activity and audio from the Amiga.
As well as this, it includes a built in clockport splitter for using additional clockport devices and a few other useful features.
The board mostly runs autonomously with a number of built-in LED patterns, but can be configured by software on the Amiga side. Many customisation options are available, including RGB values for the patterns, and the size and speed of them. An ARexx host is planned, which will allow any programs to easily control the LEDs and fan, read the temperature sensors and so on.
It's currently at the prototype PCB stage with a couple of small niggles to work out before building the final version, and there should be a few available if anyone was interested in buying one.
The board is called "Solas" (Irish for "Light"), and you can read more about it at
