Since November 2013 I’ve been building modules for my modular. The schemes for them can be found freely on the web.
Special thanks to Gaussmarkov , YuSynth and MFOS.

Gaussmarkov Gristleizer:

MFOS Ring Modulator:

YuSynth Clock Divider.
I had to make it smaller so I only use two instead of three dividers.

MFOS PSU 15V.

Bus Board.

YuSynth EMS Diode Filter.

Van Dijken Elektronica! LC Meter DIY Kit.
I use this meter for matching Ceramic Capacitors. These I cannot measure with my other meters.

MFOS Transistor Matcher.

Matched Transistors.
They are connected to each other with a little aluminum piece and glued with epoxy glue.

These Matched transistors are used in the YuSynth ARP 2600 Filter.

YuSynth ARP 2600 Filter.

The Front Plate still has to be made.

4MS P.E.G. DIY Kit.

Easy to assemble kit from 4MS Pedals.
