DIY Eurorack Modules
I hope you are having a nice summer holiday, anyway in my spare time I've made a few modules for my Eurorack. The inspiration for these came from a Quad Slew design from navs modular lab blog. In that article I came across a link to a DIY page by Doepfer which I hadn't seen before. There's plenty of simple projects there and so I set to work and ended up building a Quad Slew, a Dual Inverter, a CV Amplifier, an Audio Mixer and an expansion port for my A-137-2 Wave Multiplier II. And here's the result.
There's some discussion about the Quad Slew over on the Muff Wigglers Forum
Here's some pictures I took during the build.

All the hardware mounted (but not yet wired)
Wiring up the Mixer.
Side view of the Mixer, as you can see I glued the opamp to the back of a pot.

Here's what my modular looks like now with the new modules labeled and installed.
