My build progress

I want the wood grain to show through and have a whitewashed look, something like this but I think it’s a different type of wood, but this general idea

Currently it’s looking like this with one coat

I have used a whitewash finish from one of the big hardware store brands and had good results. A watery mix of white milk paint will give even better results, in my opinion.

Also, judging by the photo, you could get away with a wash over that first coat of finish without too much issue. I guess the worst case is you have to sand off the wash and the finish.

An update on my first case:


These things fill up fast.

Also, I made a patch cable jellyfish.


I am tempted to design a dome with some LED lighting to complete the jellyfish.

I approve of this idea.

Add slow up and down and slight sway. Even the slightest motion would look cool - even with a simple counterweight.

And this is modular, so we would need sway speed and lighting effects with CV.

It’s also the perfect size for a zoetrope top. Too much?

I liked the SN Voice so much that I built an entire synthesizer around it! I added a glide module, MIDI to CV, Sub-oscillator, Triangle to Sine converter, two VCAs for the sub-osc and tri/sine, Moog CP3 style mixer, and MS-20 filter, plus an AR/AD envelope for FM and filter control. The case is all laser cut and 3D printed of my own design.

Chapeau! Impressive build, I can clearly see the DIY ethos shining through.

One question on the MIDI to CV - what functionality does it include? MIDI note to V/Oct and note on/off as triggers/gates I suppose? Do you have extra channels or CCs for envelope parameter of filter modulation - that’d be really neat!

Also, the laser cutting, did you do that at home or did you design it and then have it fabricated somewhere?

Cheers

Thank you very much!

I used this MIDI to CV (and modified it slightly): GitHub - elkayem/midi2cv: Arduino-based MIDI to CV converter
I’m using the V/Oct, Pitch bend, Gate, Velocity, and control/modulation. Just one channel. I am not a big MIDI user.

I did all the laser cutting and 3D printing at home. I have a laser cutter I got a few years ago.

That looks amazing !!! :heart_eyes:
I am also working on a full system atm and I have a question for you then, did you use the “1K resistor on the output” between module ? i(i.e. from the output of the VCO into the mixer, etc…) I know it is not much but I am really running out of space on my design so anything I can remove is a gain.

Thank you very much. Truth be told…I pretty much just followed schematics and strip board lay-outs as is. So some functions might have them, others don’t as I look through things. I kind of forgot about that as a thing and might try going back through and adding some just to see what that does for me. About the only part of it I did any real design on was the VCA, I just mashed a different trigger section onto the Modular in a Week VCA so it’s normally closed. Works really well, I think.

The 1k resistor is to limit the current if the output gets shorted to ground or a rail (when plugging and unplugging patch cables). If you’re just hard wiring that output to another section’s input and there’s no chance of its getting connected to a voltage source, it’s not needed. (Unless it’s additionally functioning as part of a voltage divider, diode current limiter, etc.)

Incredible work! I love it!

(I love it when a module works right the first time! I mean, I did breadboard it first but…)

VCO is working, just need to tune it

I made dumb errors on the jacks PCB so I need to get those remade, but I kludged connections to the main board and tested, it’s working. Full writeup soon.

You still haven’t told us what it is…

I’ve been experimenting with leds, acrylic and mini jack connectors to spice up the signal in and outputs of my modules. These are the 1st trials / results.

I wanted to mount leds very near or maybe ‘inside’ the (in my case mini) jack connector. The leds could e.g. show a signal level or whether a signal is a positive or a negative voltage or what type of waveform an output produces etc.

The acrylic was cut and engraved using a K40 laser (which allows for very precise cuts). The underlying ring, a white one in the top and a black one in the bottom picture was 3D printed.

I made triangular cut outs in the acrylic to stop the colored light of one led from bleeding into the other led’s side.

I should maybe also experiment with white/opaque acrylic. We’ll see where this will end.
