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]

Another JLC order came in! Included the BMC040 dual logic CV mod boards: [2021-10-22 14.53.54] As well as these little Fresnel lens quad vactrols: [2021-10-22 14.53.40] Fits together neatly: [2021-10-22 14.55.04] Tried them out with a few different colour LEDs, must say they look pretty badass: [2021-10-22 14.50.19] I ordered a few different types of photoresistors, will do some testing in the coming days.

Finally got around to testing these things. Conclusion, they suck.

I tried out a bunch of different LDRs and LEDs. Here’s the best combo I could find, vs that same combo in a shrink tube DIY vactrol, vs a VTL5C3 from Thonk. The lens passes too much background light at low current, and loses too much light at high currents. I’ll be sticking to shrink tube.
