Indeed we do! I've been following your progress here and over at Muff's - looking great.

Here's mine! Freshly built!

I was going to stretch leather over the faceplate but I think I'll just gussy it up with some decoupage instead..

The "Globalizer" contains two benjolins (for patching dialogue) and one zeitgeist.
If you're interested, I can post a video later with it functioning in patch mode.

Thank you, Rob Hordijk!
Enjoy!

It also allows patches between the two benjolins, thing that is not performed in the video.

Just watched the video. Very cool. That's a great instrument.

Here's a quick test of the Zeitgeist circuit, which I recently adapted into a PCB/panel for Eurorack. I'm thrilled it seems to be working! I also did a 10HP Euro Benjolin a few years back, which you can see in the video.

Pretty cool, not many Zeitgeist builds around. Would like to build one myself, but there are some interesting other contenders around (NLC Delay no more Very Happy ).

Somewhat based on the Rungler.
Circuit has been changed multiple times.
When I get it right I can post.

Basically there are 2 square VCOs (no musical scaling)
formed with two slots of a CD4093BE.

Each of the VCOs feed a CD4517BE shift register with the
shift register feeding a 8 DA array and a MCP6002 opamp buffer.

These CVs control a F11V FET vactrol with the resistor element
across the resistor element of the VCO.

Each oscillator can either get its data from:
A "random" ring oscillator
-feedback slots on the CD4517BE,
or normalled to the square outputs on the CD4093s.

I need to buy 2 4 position switches!

Both oscillators feed a CD4070BE XOR which feeds a simple
2N7000 "VCA".

Very early days.

The Retroverb generates all sounds and reverbs. The VCF LFO is used to modulate Fc as well. The Audio output of the Retroverb acts as data input for a CD4517BE 8 Bit shift register. The clock is 1/16 notes from CV OCD, with MIDI Monotribe as master clock, it does not sound, it only makes the midi clock. The 8 bit shift register feeds an 8 bit R2R array which is fully buffered by a MCP602 single sided 5Vdd (0-5V CV). The CV controls the Fc on the Retroverb, which in-turn is fed back as data to the SR.
