My new favourite module. Yaksha's Fate! Ever since doing a slew of NLC modules, I've really fallen for those micro knobs on T18 pots. For all these 8hp Mutable DIY projects, I think they're absolutely perfect.

After initially loading the wrong firmware (figured Typhoon & Monsoon would use the same code, my mistake), I got that sorted and the Typhoon came alive!
FYI - I’m sure you know, but just in case, your panel has the Time and Bank reversed (in relation to pid’s firmware) - I made a quick hack to reverse them in the fw....
I did learn this, after going through the github comments. Thanks for the heads up! I was worried at first, thinking it wasn't working like my Microcell. Do you have a .hex file of the hacked firmware by any chance? Might be nice to tweak it, although I always welcome some quirks in my DIY rig :mrgreen:
Yes - send me a PM to remind me!

Here's a nice pair of shades!

I've had these in the build queue for 9 months. So proud of these babies! Very easy build!
Have you got a part number for those switches please?

I found them on Aliexpress here.

From the link on an old google spreadsheet for Aliexpress components geared for Mutable builds that's a bit old by now.

I have spares, if you are in the US I could pop a couple in an envelope for you if you need them.


Eurorack is an exercise in delayed desire.

Elements - built and working.
Magpie modular/elecrow PCB (black text on white resist) and oscillosuarus panel (bought together off ebay about 2 years ago).
Info: on the PCB, there is no solder resist between the pins of the STM32.

Fairly standard build approach :
- install power and reference and check it's working.
- I then installed all other SMT components. I generally work by ease of access - generally this means IC's first, then passives, electrolytic (can) capacitors last.
- STM32 was a tiny bit out of orientation, looked OK, but wouldn't program (using ST-link V2 and hex files).
- removed STM32, replacement installed. I used a lot of hi-rez photos to check there were no shorts between pads both before and after soldering (I'm hand soldering). It programmed fine (hex files from hadesbox github). Leds flashed at power up.
- installed the "blow" pot - I could now get "firmware update" mode at power up - so clearly working.
- installed all the trimmers. I could now get "calibrate" mode.
- Also got some basic audio output (given no controls installed). Installed about half of the pots - it made controllable audio.
- Installed all the sockets - no problems.
- installed all the remaining pots: nothing, no audio, no leds at startup. Dead short across the +3v3A supply rail (IC2 running hot, output about 0.2V)
- Removed last batch of pots, cleaned up pads, reinstalled one at a time - working fine. Probably a combination of a bit of slight solder overspill and poor alignment of PCB resist layer.

I now have a couple of spare STM32F40's - see separate post.

Started off trying to build Branches. First major failure, still don't know what's wrong with it.

I figured: screw it, I'll try Ripples, and if I can't get that going, I'm giving up on SMD. And it worked.

Out of sheer stubbornness, and not out of any real need for the module, I gave Branches another go, from scratch. And it worked.

I put Oscillosaurus panels on both, and I am super proud of them. Especially because I have encroaching Parkinson's, which makes soldering SMDs... challenging. So f--- you, Parkinson's.

Next will be Tides v1 or uWarps. And learning to flash ICs.

Hey all, How's it?
Has anyone had any success building Veils 2020 using AS2164 or SSI2164? Other folk have touched on this but having tried the recommended solution of changing the RC and CC values it makes no difference.
The issue I have is localized to channels 1 and 3....on several modules.
