The MiniMaximite Computer
09 November 2011
We now add to the Maximite family with the miniMaximite; a small, low-cost version designed for use as an intelligent controller to plug into your creation. It is fully software compatible with the original Maximite so you can develop and test your program on the larger version, then transfer it to the
miniMaximite when you are ready
to screw the covers down.

Upgrading An Ultra-LD Mk.2 Amplifier To Mk.3 Standard
26 September 2011
This teensy PCB lets you add the vital modifications to an Ultra-LD Mk.2 amplifier to bring it up to Mk.3 performance. We are doing this so that all those people who built the Ultra-LD Mk.2 from the August-September 2008 issues will not be too annoyed with us for superseding it with the Mk.3 version. After all, we want to keep our readers happy and content!
