- SN-Voice: Primered the front panel (not sure how well that’s going to work. I’m using spray primer and it’s 17 degrees F outside. It may get a coat of white latex paint if it doesn’t). Figured out an easier way to do pcb->panel connections instead of making my own cable rigs. Still need tempco, but going to work around it at first (putting in headers, and just using a regular 2k resistor for now)
- MPS: Most of the way there. Still need a couple of caps (the polystyrene ones) and panel components.
- Tried to build Rene Schmitz’s 4069 VCO. Thus far not successful. Not sure where the problem lies.
- The new rack chassis: Figured out the existing panels will need widening if they are to accomodate 1/8″ jacks. Given the material is some kind of reasonably study metal (steel? aluminum?), this could be a challenge)
- New thing: It’s a re-implementation of the 1970s/1980s Remco Sound FX Machine. The schematic is somewhat based on the Saratronics SARA-002, but with some improvements (specifically: added a switch for one-off or constant operation, and fixed some things that looked weird in the schematic). Working great in prototype so far. Working on a fancy enclosure (ok, a cigar box, as usual, but it’s going to be painted up all fancy-like, so it’s fancy, dammit!)
- I must really like the SN76477 – in addition to the two projects using it above, I’m also planning to build a Thomas Henry SN76477 SuperController. I may build a second Sound FX Machine box as well.
- Also trying to figure out a way to mount the power supply without electrocuting myself – I think it’s going to get its own enclosure, and hook into the cabinet(s) via XLR connectors.
- Even though I’m not a major Atari Punk Console fan (you get twice as much fun out of a CD4093), I went ahead and got a pack of GetLoFi’s APC 2.0 PCBs. If nothing else I may make a couple of little kits for friends who want to get into SDIY.
- I’ve got some other PCBs enroute. Looking forward to getting them.
- Debating some Hi-Fi type projects (chipamp, maybe speakers). Maybe when some of this other stuff is actually done.
