SDIY progress report – 11/8/2009

Progress on the Synth-DIY front recently:

  • PS3100 Resonators – Done! It’s in the rack, though I suppose I should put the knobs on the pots…
  • TH SuperController – More done than before. I suspect there are still some problems in the PCB->panel connectors which need to be addressed. Noise source and LFO are definitely working. S&H and gate delay may still need some attention.
  • XR2206 VCOs – still waiting on PCBs (week or two?) In the meantime, I’ve put all the components needed into a bag, so when the PCBs arrive, I’ll be able to dive right in and not dig through my parts boxes looking for appropriate values.
  • Gristleizer – Done? I discovered an incredibly important mistake that I had made (see build note #1 in that first post of the thread). Replaced the JFET with proper hole spacing and it seems much happier now… I think it’s going into the metal outer enclosure of an old CD-ROM drive. That looked suitably “industrial” for my purposes.
  • Jürgen Haible 36dB Filter/Phaser – Sketched out how I want the panels to look. Just need to drill them and then mount up the panel to the PCB.
  • Made some more design decisions on the next-generation sequencer. Looks like it will be 1×16 or 2×8 switchable (with the possibility of  chaining additional units to 1×32 steps in the future) Still some ways off, though. More recently, I am interested in Fonik’s Voltage-Controlled Pattern sequencer, though I think a microcontroller is a better idea here than just an ADC…

I also started plotting how the expansion of my system beyond two rows is going to happen. It’s going to involve a DIY cabinet and Vector rails. More details soon. I also accidentally a x0xb0x – I think I’ll have the PCBs as early as tomorrow, but parts will be dribbling in from now until the new year, I think.

While I’m at it, wanna see the modular in action? Here it is:
