Stereo Pendulum

[DGWVI]

I've only got one amp here, so I can't test the stereo functionality properly, but each side does work, and they both offer up that glorious Pendulum throb. Pink LED for status, purple for rate indicator.
Only mod is an A50k for the gain pot, as otherwise it's loud as heck

It's not that I haven't been building, it's that most of it hasn't really excited me . Too many people requesting boring drives. I also forget to post

I did pull out a stack of ~30 pcbs that I'm gonna try to have done in the next week or two, depending my availability

30 pcbs in a week or 2 now thats a milestone ive yet to accomplish .

Clean build, I like the knob choices with that enclosure! I just built the mono version of this and love it. I went with A100k for the volume pot but I just told @MichaelW in a post that I'd probably try A50k or B50k to tame the volume, so I'm glad to hear that was a good suggestion.

I just took on a new day job, so I'll have a lot less time, but I think I can knock out at least 20 in two weeks. Tomorrow should be nothing but building

I've used the A50k in the last few I've built. Not sure when I'd ever need as much output gain as the build doc calls for

It depends on the resistance of the LDRs used.

I think I've only used 5516s correction- 5528s in the Pendulums. I'll socket them on the next one. Do you have a preference?

This is interesting, I had assumed you used the KE-10720 because you used red LEDs and the GL5516 has a peak at 540nm vs the ~630nm of red LEDs. I've always used GL5516 with green LEDs and KE-10720 with red, but seeing as you're having good results I guess it doesn't matter as much as I thought.

Just checked to make sure, and I was mistaken. Been using 5528s. So, 10-20k vs the 5-10 of the 5516, but the same spectral peak
