Ok, this one is weird and sort of ancient, but I finally finished it, so there.

This is version 1 of the very first run of these. I built most of this when I got it, maybe 6 years ago - it was right around the time the TTSH came out originally. But I didn't have a case for it. So it sat, mostly untouched, on a shelf since then. I moved since then, rebuilt my studio in the new house, put it on the same shelf it had been. A few years ago synthcube started a pre-order for the cases for these, so I bought into it, and finally got the case a few months ago. Some more sitting around ensued, with a few brief spurts of activity, but today everything seemed to fall into place to actually get everything together, and now it is! Still have to calibrate it - hopefully I won't wait another 4 months to do that.
i have 3 of them but only one is finished. damn... but can you tell me where can i get those caps?

I built a 12u case this summer..


IMG_0815.jpeg


I wanted something to match my desk..


IMG_0812.jpeg


Working backwards, here's the finished product with genus modu bus boards and acopian power supplies. There's a powder-coated mesh back that goes on after this.

Birch ply and pulplogic rails before stain and wipe on poly.

Cardboard prototype helped me get the angles right.

..And yesterday I replaced the linear supply with switch mode supplies. Lighter and eliminates a bit of mechanical noise.

Very nice! I like the case a little less fancy, like yours! What stand is that you have it on?

^ Dayum. Looking really clean as usual. Your builds are always a highlight on here. How much did the panels come out to?
Thanks! I think if I had only gotten one panel done it would have cost around $25, but I put a few in the same file so they shared sides and they were only about $15 apiece.

Those particular ones were three of the four extra WASD caps that come with some Ducky keyboards. Don't ask about my mechanical keyboard collection. You can get similar things on mechanicalkeyboards.com or a similar site.

It's on an amp stand, designed to get small guitar amps off the floor.

Re; the ATOM .... I have one. LOVE the very identifiable sounds it makes (that circuit has a ton of character that produces such an undeniable ~identity~ .. so to speak) ... yea, love the sound, but them tiny trimmers packed so tightly really suck. They're high quality components, so it's not that the module is made of crappy stuff .... it's just how difficult them tiny little trimmers make things.

Which has lead me to be on the lookout for some solutions. I found these ..... FORTY BUCKS!

Those or something like them, in addition to other manual variable voltage sources (sticks, ribbons, wheels, foot controls, and so on). But yea .... did I mention they're only FORTY BUCKS EACH!!??!?!

Best I can tell those are 60mm faders .... same size I use on my DotCom dual VCF I cooked up. Sweet.

As far as I can tell they're hard anodized. I haven't scratched/scraped the finish down to the bare aluminum on any of these yet. Which you certainly would if there was a problem - the little tightening tool they provide is some serious cheapness, it's constantly slipping out of the slots.

Oh - those are from synthcube, I think. They're actually manufactured by the Logan Solomon folks, or what's left of them, and they made a batch in one color scheme for synthcube, and another batch in a different color for their own use. I was sent these by LS, but don't really remember which batch they're from.

I haven't posted in a while but I did build a few things this year.
Modded Danelectro Spring King, to add pots for the PT2399 inside. Adds a lot to an already nice sounding pedal.
Image

Installed Mic-Parts capsule and circuit into an MXL 990 condensor mic.
Before:
Image

After:
Image
Image
Image

Built the DIYRE Color Palette 500 modules in this rack, plus a bunch of Color sub-modules.
Image

And this Arp 1601 clone.

I documented the build here: https://www.kvraudio.com/forum/viewtopi ... 5#p7679785

I feel like there was something else but I can't remember now. :doh:

I've never heard of that before ... I have one of those MXL990 mics (w/shock mount), had it for years. Thanks for the exposure, I've gone to the Microphone-Parts website ... lots to see .. thanks again!!!

I went with the RK47 capsule which gives the mic a much smoother high end and a nice bass boost. The new circuit makes the mic less noisy and about 6dB louder than the original. I also adds a Omni pickup pattern, which makes it useful as a room mic. I have another unmodded 990, so I want to do some comparisons.
The 990s were my first condenser mics. I have some decent LDCs now, so my MXL mics were just sitting in the closet for years. I already found that the modded version sounds fantastic on guitar cabs and for close micing a speaker on my 2600.

I'm thinking about building one of their V251 mics next.

My homemade take on the PT2399 delay.

I wanted a couple of things: it should be usable both standalone (like a guitar delay pedal), and as a simple signal in, delayed signal out module for building complex patches. It should also have voltage controlled delay (because if it's not voltage controlled, it's not modular). I wanted to keep it compact, so I didn't add any VCAs - if I want VC repeats, that can be patched externally. Arranging the knobs zig-zag on a 6HP panel gives just enough finger room.

The circuit is quite standard - in particular, the CV mixer was originally taken from a version by Scott Bernardi - but I took a while tweaking the values to get the behaviour I wanted. The input control avoids overloading the chip, and set at half way it takes a +/-5V signal without clipping. The signal in and out of the chip is filtered at 5kHz, so the delays are quite clean, although they get a bit crunchy if the delay time is too long. The trimpot on the board adjusts the delay CV mix so that the chip just starts to break down if the Delay control is turned up full. Similarly, the Repeat control gives runaway feedback just before maximum. The main output is the signal from the delay only, the mix output has the input signal plus the amount of delayed signal set by the Mix control.

The main circuit board is spot soldered to matching tracks on the front panel board, which is not something I would recommend for a commercial circuit, but is quite sturdy enough for a home build. It saves space on connectors and mounting hardware, and allows the main board to be a little wider than the front panel.

Any chance of getting a schematic? Looks like a lovely delay and has all the features I would want as well.
I started doing right angle front panel boards for my DIY builds although I use right angle headers for more mechanical strength.
Did you CNC mill the board?

I'll have to draw up a clean circuit, it's all rough notes right now. The PCB was manually designed, laser printed onto blue transfer paper and etched. (Maybe one day I'll learn to use a PCB layout program, but for now I enjoy the design process as a brain workout. it's a bit like doing the daily Sudoku.)

This is number 2 of a three-peat of o_c's. The first was a full size, built for Mr. Rex Coil. Then this one. Next up is a 1uO_c, which may be a bit before it's completed. This one was kind of tricky, as I'm right in the middle of moving, and my tools and such are still here but most of my modular stuff is over in the new place.

This morning I assembled my TSynth (DIY Teensy 4.1 Polysynth)
A nice build that lasted about 1.5 hrs. A surprsingly rich 12-note polysynth for about 150-170 euros
