I'm trying to understand the normalizations in the wiring diagram, and tried to read through the other posters that built a banana version of this board. But it seems that this has managed to exceed my brain capacity, so stupid questions galore here we go: So, for all the normals to be behind a swit...

Is there any reason why I should not take the B+ and GND from one pin on the PCB for all the pots, switches and leds? Other than the mechanical of course, but as I'm building my own PCB for the panel components (for reasons) that shouldn't be an issue. So is there any electrical reason for taking th...

Well, the Teensy 3.1/3.2 processor board used by the O&C module has a USB port, and the Teensyduino libraries support MIDI in and out via that USB, so it may be possible to add this to O&C without too much effort. Worthy of more investigation...
Dude... This would be a KILLER feature for O+C!!!

4ms DLD not turning on?

Hey! I just bought a 4ms DLD, and it worked for couple of times, and those times it was a great module! Unfortunately, it stopped working two weeks ago, and doesn't seem to turn on anymore. The power cable seems to work on other modules, the other modules work in the cases I tested the module, and t...

The reason for this would be a simple way to beat match the equation to a clock by hand. If I would be able to adjust the pitch parameter by 254.99 or such, that would help out a lot. Is it not possible to use decimals in the bytebeat equations? Not naively. The equations seem to be built on intege...

Hey there you magnificent people! I was playing around with "Viznutcracker, sweet!" on v1.2 firmware, and I was wondering would it be hard to expand the precision of how fine the Pitch-parameter in the equations would go?

Lil Sidrassi - Alternative for 2N3819

Is here anyone who would be aware what the 2N3819 transistor does in the Lil Sidrassi paper circuit, and if it can be replaced with something else?

DIY-breadboard Mikrophonie seems to distort

I received this layout for a Mikrophonie on breadboard (attached to this post) and managed to build it. There just seems to be this issue that it distorts very easily. One friend suggested that it might be due to offset issues, but we weren't sure what part of the schematic takes care of that. Any a...

Another question. I have used with my Ladik Q-010 the option to quantize only one note in octaves to tune the oscillators in correct tuning. I tried this similar method with Quantermain, but encountered an interesting problem. When in seminote scale, the basenote drops by one seminote somewhere arou...

Enclosure for Power One HBB15-1.5-AG

I'm looking for some recommendations on a good enclosure for the Power One HBB15-1.5-AG PSU.

I did stumble upon the Random*sour...

Same happens to me only if I'm wearing non "grounding" shoes, like when I'm touching the ground with my bare feet/socks. Did you notice if that happens when you're not touching the ground, too? Ground as in the floor? I've actually haven't tested with my shoes on, as I usually just keep my shoes of...

Which make and model of supply feeds the Synthrotek? There was a grounding problem with some made by an OEM that were supplied by several companies. I think the brand was Mean Well. The model that I've used before is this one: https://www.adafruit.com/product/352 On the label it says GEO651DA-1250,...

Is it really a "vibration" or is it an electric shock? People here are talking about it as if it's a shock, and that may be more likely, but that's a much different deal from a mechanical vibration. Edit: one way to tell the difference would be seeing if you can still feel it through a thin insulat...

Sounds like your case isn't properly grounded I think. I had this problem, and it turned out I had it plugged into one of these but someone had snapped off the ground plugs, so nothing was grounded right. Got a normal power bar and it all got better. Yeah, that's what a lot of people have been tell...
