Re: crazy concept: potentiometer with a 1/4" jack through it?

For attenuating inputs, I feel a small slider along the plug on the cable itself would be the most elegant and usable design. I just don't know if there would be sliders thin enough to fit nicely in there. I was thinking of a miniature thumbwheel pot. Or even a sub micro toggle that gives you a cou...

Re: I hate LEDs

Yeah, this is really only a thread to explore the idea. I cannot see an actual way forward without a backer with a tremendous amount of passion. I think a more practical approach would be to have a kit with a single RGB LED. You could mess with it, and record the colors that you require, and make a ...

Re: panelizing two different pcbs

With JLCPCB prices I wouldn't bother with panelisation unless you are into high volumes. You might save a small amount but then you have to deal with cleaning up the edges yourself. AND if you are doing high volumes, ordering JLCPCB through the website is the wrong thing to do. Once you hit 200 boa...

Re: I hate LEDs

Adding a slew of LEDs to your system is going to start hogging on your positive rail. Not that it isn't possible...it *is*...but there are some significant hurdles. Each RGB needs to be told what color to be...which typically requires a processor. And it needs to be able to save the state/info of ea...

Re: panelizing two different pcbs

on the JLC site there are options for "panelize by JLCPCB," and "panelize by customer." Be very careful with the total size...we did a panelized product, and even though the pcbs were cheaper, shipping the larger panelized stuff added more than we saved, AND it added time to the build. Ultimately, I...

Re: Folktek / Cause for concern?

This bothers me too. I also hate the 'puzzle box' approach that manufacturers like folktek and to some extent mannequins take. i'm looking for a device that helps me produce music, not a rubik's cube. Yes, this is very salient. Ultimately, I think it's the reason most of us hate "menu diving"...it'...

Re: copper bus bar thread

I think that product you posted is the same as Star-Brite 512 for cleaning copper kettles...which is essentially just a buffered sulfuric acid solution with phenothalein added to indicate pH. An easier non-fuming solution to cleaning copper (and cheaper and safer) is citric acid. In the distilling i...

Re: crazy concept: potentiometer with a 1/4" jack through it?

I really think the main parts you need already exist. Try googling "hollow shaft rotary displacement potentiometer." We used one from Contelec that had a 6mm D shaft cutout, but they had other models. We used another one from overseas with a 32mm opening for a bezel-controlled light insert ...WDA-72...

Re: solder/flux residue cleanup

Whenever I use IPA and a brush to clean flux it seems to just suspend and spread the flux and then sticks back onto the board as a thin layer as it flashes off :confused: Doing it several times does the trick. But honestly the boards I typically do are just too large to even want to bother cleaning...

Re: crazy concept: potentiometer with a 1/4" jack through it?

If you change your requirement from "potentiometer" to "encoder," then this isn't actually a difficult thing. Rotary ring encoders are pretty common (Like on the MMXX T-APE) especially for the automotive industry. Sticking a jack through the middle wouldn't be hard...you would just need to mount the...

My MRCC arrived today!

I was originally going to build a sort of a MIDI routing ...

Re: Korg Electribe pad repair

That's good advice, especially if the carbon is worn off. If it's just dirty, gentle application of a good white pencil eraser will work. The pink is too aggressive and will remove the carbon coating.

I use Easy EDA a lot. For the holes, the best way to do things is to make sure the pad of the component is centered so that the 0,0 point is in the middle of the hole you want.

Re: solder/flux residue cleanup

1. The white residue is not conductive 2. It's a hard shell. You can flake it off gently with a razor, but a plastic spudger works well and you won't scratch stuff 3. Use some IPA to float the particles off the board...I pour it off into a kimwipe. 4. Leaving it on won't hurt...it's just unsightly. ...
