What's that? Looks incredible!

The multiwave mega from parasit studios, microcontroller based wavetable synth - the guy is a genius. I bought the PCB with the microcontroller and decided to add the OLED option. He only provides the hex file for the OLED and that's it, because he doesn't think it's DIY friendly, which he's not wrong about. I got my friend who works at an aluminium fabricators to cut the rectangular hole in the enclosure, but he had trouble with it being a diecast box and had to make it a lot bigger to get rid of cracks.

Rectangular holes are tricky - I've done them by drilling out enough room for a power file and using that to make the hole rectangular, but it's not perfect and some hand finishing is needed. A laser cutter would do it but it would have to be a bit more powerful than a hobby one.

And the new econo one, using through-hole parts all sourced from Tayda, and a very inexpensive Tayda case in a pre-drilled standard format they do for various Pedal PCB effects, which they also printed for me:

Compared to the one pictured directly above, this would take a hobby DIY builder maybe 1/4 of the build time. Once it's well tested all the details will be available here: https://github.com/Passinwind/PW3B-LPF

Has anyone built a frequency split pedal here? Either fixed or variable. Single input, high and low output. 

Yes indeed. I used a DSP board from MiniDSP that included programmable EQ capabilities as well.

Woah - awesome! One of my favorite pieces in the studio. I like how you did the channel select - really makes sense. How does it sound?

I used the original factory schematics 1:1, also for the switching.

I compared the copy with the original. They sound the same to my ears.

It's not a DIY effect at all but thought this would be the place where gut shots of a v2 colourbox would be appreciated ... lots of things going on in there. And no I couldn't work out what the HPF was doing to work out how to mod it...

Nice - I just meant that the foot switches look very usable in a pedal context.  The one in the studio is pretty smashed up and needs a service (channel 1 freq knob can trigger a cascade of brutal feedback at it's frequency setting and needs careful wiggling to stop), and has been hacked about so the limiter is no longer available.

A couple of kits assembled and working.

 

HPF/LPF - https://schalltechnik04.de/en/instructions/vong-filterung - kits from https://www.musikding.de/VONG-Filterung-filter-kit

 

12dB/octave rolloff, variable frequency.

 

Really must prettify this somewhat. At least the enclosure was pre-drilled so it doesn't look like the holes were made with a hammer and blunt chisel.

Subsonic filter - https://guitar-electronics.eu/en_US/c/SUBSONIC-FILTER/84

 

24dB/octave rolloff below 27Hz (see the PCB for details).

If you like my coffee joke I have a spare sticker … though if you did that enclosure for the subsonic filter you need nothing from me!

I liked the coffee joke, I'd love a sticker please. No, I didn't do the subsonic filter - that's an option they provide.
