Simple Synth Projects for Beginners

Which reminds me of this :

Passive multiples, and more

Matthew Skala (from North Coast Synthesis) that we keep linking to just posted a set of easy-to-build unpowered module designs, starting with eight holes in a narrow front panel and a wiring diagram for a passive multiple, and expanding that to a mixer, an OR combiner for gates and triggers, a fixed attenuator, a low-pass filter, a high-pass filter, and an envelope follower. The article includes a 2HP Eurorack frontpanel, but expanding to Kosmo is of course trivial.
