Quantisise has four outputs per section (VCO, VCA and two S&H outputs).  Each is monitored by a different color LED, green for the VCO, yellow for the CV S&H, red … Read More

Here is a wide range, non-precision, and somewhat unstable voltage-controlled oscillator (VCO) with just a pot for initial frequency, a CV input attenuator, a triangle (-0.5 to +4.5 volts) and … Read More

Here’s the populated front panel. It is just for show at this point. A view from the back. And the final block diagram for one of the six sections.  It … Read More

I needed six DC-coupled linear VCAs for the Quantisise project.  I discussed my requirements on this Muffwiggler forum topic and decided to use three PC boards, purchased from Dr. Sketch-n-Etch.  … Read More

Here is a CGS SSG board, assembled as a dual S&H with a one-shot circuit.  It’s the first of six identical boards for use in the Quantasise. The SSG (Smooth … Read More

I built a stand-alone power supply that delivers +/-15 volts @ 800 ma to use as a bench supply for testing modules under development, and also to use as the … Read More

My banana cabinet is finished! It combines 5U modules, a rack of BugBrand, and my custom CGS Serge panel into one cabinet. Note the vertical alignment between the CGS Serge … Read More

My current project is underway. The panel was completed today (click the image for detail), but it’s only a facade. Behind the panel it’s empty. All of the modules are … Read More
