we have uncovered a small stash of PCBs and Bridechamber MOTM panels for the TH Magic Smoke Sheboygan VCO... :yay: :yay: :yay:


however unless Magic Smoke magically re-surfaces, or TH can be persuaded to move the rights away from Magic Smoke and to someone else (Fonik?) these may be the last of their kind :despair: :despair: :despair:

the last ones we have are listed on our store, in full kit and pcb+panel+bracket bundles... we hope these find a good home on someone's MOTM system!

Oh, is Magic Smoke MIA?

I saw these on your site a couple weeks ago, which inspired me to look at the Magic Smoke page again & the different TH PCBs.

I have & enjoy all of Thomas' books (except for the recent-ish PICAXE one, which didn't seem relevant to pick up), but have never got around to building any of his designs...

I did an evaluation of this PCB back in 2011 and documented it on my website. I've used this VCO quite a bit since then. I did find a lot of crosstalk in the noise and isolated the negative supply to solve it. Later I discovered you can eliminate the negative supply completely. I don't know if this mod was ever incorporated into the PCB. Photos and my panel design are at TH-101 “Sheboygan” 566-based VCO Module
