Another JLC order came in!

Included the BMC040 dual logic CV mod boards:

BMC040 dual logic CV mod

I was recently building a dual logic module by Barton, BMC040 Dual Logic. This module offers two 2-in-1-out logic gates with a knob for adjusting the logic gate type (AND/NAND/OR/NOR/XOR/XNOR). I realised it’s adjustable logic gate type is implemented as a analog voltage being read by a PIC. Here’s the original circuit: [image] (non-orthogonal lines in a schematic should be illegal, but that’s a different story…) Notice how L1 and L2, the potentiometers setting the gate type, are just volta…

As well as these little Fresnel lens quad vactrols:

My build progress

Anyone remember @lookmumnocomputer’s video on the Solaris 50? [MEGADRONE That is commercially viable? :O The SOLAR 50 Synthesizer] Ever since I’ve been thinking on how to recreate those cool semi-transparent vactrols. Here’s my attempt using a PIR fresnel lens. I’ll get them fabricated and experiment with different LEDs and LDRs. My first thought is to build @EddyBergman’s LPG with them. [image] [image] [image]

Fits together neatly:

Tried them out with a few different colour LEDs, must say they look pretty badass:

I ordered a few different types of photoresistors, will do some testing in the coming days.
