Ray Wilson was the guy behind . He was a huge contributor to the Synth DIY scene. He designed a lot of cool projects, offered kits, schematics and a huge amount of tips and tricks for beginners. He even wrote Music From Outer Space a book on how to build an Analog Synth. MFOS kits and PCBs are still available through various resellers (see synthcube).

KiCad has been updated to 4.0.x branch and it is strongly recommended to use it for all your new projects, instead of the good old BZR 4022 from 2013.
But sometimes, when you want to open an old design without too much trouble, it’s more convenient to just install the old version.

A friend gave me an old defective ITT MX20 Multimeter.
The multimeter is still currently sold under various brands. It’s a very rugged, IP67, electricity oriented multimeter.
The multimeter, now in working order.

In the previous topic where I explained
how to create your BOM from the KiCad’s XML export, I mentioned my own script generator, written in Ruby, xml2csv.rb.
It’s nothing fancy at all and there are already tons of BOM generators out there, but it’s always fun to create your own tool, suiting your very own special needs.
