Re: Something New from Doc Sketchy
UPDATE: I just finished laying out the 4-channel morphing scanner design with auto-scaled CV range on a single PCB which is 4" x 6.4". It's pretty elegant. I'm making one for somebody already. If anybody else wants one, please let me know.

Re: Behringer: practices, ethics, morals and legitimacy.
But I get it - at the end of the day to keep prices rock bottom - that takes abusive cheap labor. Hopefully there will be a day when that is no longer the case. Actually, rock-bottom prices require efficient manufacturing and economies of scale. Keeping costs low doesn't necessarily mean abusing or...

Re: Something New from Doc Sketchy
UPDATE: I wrote the little code for the resistors, and now I can use the PDN90RC function to calculate all the RC time constants for the phase displacement network, set the capacitor values, and then use my new E96RES function to find the nearest lower value of resistance from the E96 series. By sub...

Re: Something New from Doc Sketchy
for your next trick, make it generate an optimised (fewest different parts) BOM using only E12 values :sb: Actually, all kidding aside, I'm doing exactly that, but with E96 values. It won't be an "optimized" BOM, though -- I'll have to specify the C values I want to use, and then it will automatica...

Re: Something New from Doc Sketchy
What does that mean for Frequency Shifter owners of light year's past? Nothing. I used a thing on the internet called QuadNet to design the optimal PDN for my previous design, and my new code gives exactly the same values. The issue was that a) QuadNet is a pain, and b) it wouldn't allow me to desi...

Re: What are you listening to now?
I'm listening to the Steven Wilson remixes of classic Yes albums. Here is the first track from the oldest album he remixed: Yours is No Disgrace, from The Yes Album. I'm sorry, but this is absolutely sumptuous. Listen to this carefully with headphones. If you don't like this, you're dead inside. htt...

Re: Something New from Doc Sketchy
Tonight, after much searching around, I finally did something I've been wanting to do for quite a while, ever since I've been building frequency shifters. I figured out exactly how to arrive at the optimal design of a 90-degree phase displacement network, and I put the solution into an Excel spreads...

Re: Something New from Doc Sketchy
HAPPY NEW YEAR, MOFOS!!!!!!! Here's hoping that 2021 is just a bit less of a clusterfuck than 2020 was (although my personal 2020 wasn't too bad at all, actually -- at least, once I got out of the hospital in March -- because I've felt totally fine for the last nine months, and I managed to get quit...

Re: Something New from Doc Sketchy
Tonight, I made the 1U-wide 5U panel for the 4-Channel scanner I stuffed yesterday. The slot for the fader turned out quite nice, and everything fit perfectly the first time. Also, the module worked perfectly the first time -- no layout errors, no solder bridges, no mistakes. That was a welcome chan...

Re: Something New from Doc Sketchy
Merry Christmas everyone! (actually, it's Boxing Day, but whatevs) So, a couple of days ago, I realized that there was a small design error in my 4- or 8-channel "noiseless scanner" design. It was a very minor error where I failed to buffer the voltage coming from a rectifying circuit properly, so t...

Re: Something New from Doc Sketchy
I don't plan to build another one of those fuckin' things for quite a while. Sell it to us, Dave. :hihi: For the record, they are a tad good. :party: I wanna sell a 5U one -- they are so pretty, and soooo much easier to build (plus I can build the whole thing rather than just the guts). 15_Finished...

Re: Something New from Doc Sketchy
I got the QFG in the mail today, so I'm pretty relieved about that. The testing and troubleshooting only took one evening, and a pretty short evening at that, which was a bit of a pleasant surprise. A couple of solder bridges, one inverted diode, and a few resistor value changes to dim some over-bri...

Stop the world: I wanna get off. So, I'm so busy with schoolwork right now and I've fallen far behind on my builds for people. I finally got a stuffed and tested Frequency Shifter on a 6" x 8" PCB out to a customer in Iceland today, and I think I'll be able to finish the second Serge-format Quad Fun...

As we say in the Euro world; "If you can't go wide, go deep!". Or something along those lines. :D Yes, that's more or less exactly the situation with homebrew eurorack.

Well, I'm only back in this thread because one of my friends has been banned so I wanted to see what all the kerfuffle was about. It wasn't about much, evidently.

He was in Bill and Steve and Chris and Rick's excellent adventure. Here's a couple graphics of the interpolating scanner circuits. These just generate the control trapezoids for four channels -- they need to be plugged into a quad linear VCA to make a complete scanner. A unique feature of these is t...
