There is a 20m tall installation of Peter Vogel (1937-2017) in the Max-Planck Institute in Saarbruecken (Germany), which is next to my office. What coincidence!

I know this installation since 2003 and was pretty impressed by its size. It is in the hall of that institute and you can have a look at it during business hours. There are more buildings on the campus that have art as part of the construction, which are open to the public.
Unfortunately they turned off the sound (which isn't that impressive), but you can still see the 300 LEDs starting to react if you come close.

Just about finished calibrating Slopey - panel from Loudest Warning, built by me. Lots of help from Cygmu and thebadproducer for the funkier mods and calibration routines. The recreation of the Model 14 did take a lot of brain power but initial findings very positive. :guinness:

Favourite addition is the Cycling jack on the DTGs, which causes them to cycle when a gate is received.

Must continue to work on my wiring tho - this one is pretty dense, and I’m sure I can continue to make this tidier!

Nice work! I really like the standoffs for working on the back. I've never done that, but I'm about to start! :yay:

Thanks! It was actually a nightmare of adjustments throughout to get it all to fit, made worse by the idea/need to use chicklets for the Model 14 at the 11th hour. Modular Tetris!!

Submixer/adder (for analog drum modules that have their own level knob): 10 mono inputs, 1 output with gain control.

So far the first module where I made the front plate first for obvious reasons. 6HP, but possibly also doable on 4HP.

CGS gate block inspired/derived quad gate boost/buffer. Takes a smaller gate and makes it 0V-9V. Image

Pimp your bass drum: ProCo Rat Distortion Pedal (schematics here) adapted to 6HP by combining it with the CGS stomp box adapter. Instead of 9V it works from +12V as well.
Addtional feature: Toogle switch between silicon diodes (1N4148) and germanium ones (AA134). The silicon diodes produce a somewhat brighter sound. Thus you might want to try diodes with even larger voltage drop, such as LEDs.

got totally inspired by the kompas build in this thread (thanks!) so made one from stuff i had on hand. it's janky but hey it works and it's a cool little module, been having lots of fun with it. that arduino nano has been sitting in a drawer for months, get to work nano.

Had to get some panels made, but got it sorted. The Drive control is rather subtle, might be my ears, maybe.

According to Ken Stone, these 1J24B valves draw less power than a LED.

Finally finished the second frequency shifter I started building early this year. The customer's was done over two months ago. I could have been done a bit sooner, but a couple of easy-to-build kits jumped the line.

My Latest Additive Synth prototype

Post by MikeDB » Fri Oct 25, 2019 8:12 am

95% digital so possibly not of interest to all, but you can see some of what it does at
http://inposesynth.000webhostapp.com/

Fits a standard Eurorack provided it's not too slimline a case. Love to hear any comments at mikedbryant@live.com

I aim to add the ability for people to actually try the real hardware online but need to change broadband supplier so I can get a fixed IP address.

I just built my CGS Programmer/Sequencer.
The stage indicators are LED rings around the push buttons.

The picture quality is bad, again...

After a while, here is what I have so far.
Several modules working and a powered case with a power distribution.

I just need to build a small output module for headphones.
But I'm quite happy with the result for now!

PSU is from Elby design, and I used the bad producer's guide to build the case.
I wonder what to build next... I still have most of the MARSH PCBs left.

That boat is coming together very nicely.

What’s the power distribution board that you’re using? I don’t think I’ve seen those before.
