Hey everybody. I was wondering if anyone prefers either of these trimpots
I am thinking of going different format of bourns. But am interested in anyone’s thoughts.
I have a project For CV Joystick with stackable PCBs and it seems like the trim pots have a clearance issue. The brass 3m stand offs Don’t seem too come in the right height for proper contact with the expansion header. Although I do have nylon version that work height wise. I would prefer too make it easy to use brass stand offs. I plan on redoing the PCB after Redesigning with a proper LED driver. Then releasing the files. HackaDay Project Witches Brew
I like the brass multi turn. The box gives you something to either glue to a face plate or pack up underneath from a circuit board to reach a face plate and the brass knob means you can solder extensions like metal tubes or attach gears or levers. Takes up less real estate on a breadboard too.
That is a pretty neat variant. I am thinking of giving extra long headers a shot, Because there should really be a little bit more room for components even some of the caps are pretty close too top PCB. I might order some of these. Because it would be interesting to have access too the trim pots while they are stacked. Thanks everyone for the ideas.
Oh, that reminds me. I’ve been meaning to pick up a few of the splay legged single turn open frame ones. The Yusynth steiner filter I made PCB for has footprints for them and the BOM specifically calls for single turns. But all I have on hand are the box style multi-turn right now. I could make them fit…but…trim pots are cheap enough and I’m in no hurry so would rather pick up the style the board is designed for.
I made a similar mistake when I built the VCO-1 from Skulls & Circuits … the simplest solution would have been to simply build the trimmers on the back.
as mentioned it comes down to what your trimming and the accuracy.
The standard trimmer is good as a replacement for a normal POT where you need small footprint, set and forget with easy rough accuracy,
The Bours can be a pain without a trimmer driver (which wont work with a flush panel) and can be frustrating if located in an awkward spot. But they are the best way to get to x.xx accuracy ( and hopefully stay there )
Yes man, I can totally understand it, especially because I listened to my gut feeling beforehand and soldered the connector for the power correctly on the back …
That moment came when I wanted to unsolder the trimmers and the first solder pad tore off …
