Title: DeadAstronaut FX - Astro Flanger
Post by: Strat68 on April 30, 2025, 01:07:53 PM
I started build the flanger but when it gets to installing 9mm pots they won't all fit when correctly oriented.  Either the type of pot I've been using for years are too big or is the board incorrect?

As one cans see these type of 9mm pots, when correctly oriented per pin 1, will interfere with each other and the switched.
Thanks

Have you got a link to the build guide?

Where does it say that it uses board-mounted pots?

Good point.  It has holes to connect the pots which match a 9mm exactly to I made an assumption.  I'll just use 16mm ones and wire them which is a pia.  The build doc only specifies the values and not the size. 
Thanks

Thanks for the warning.  I have a couple more to build.

Pots are on wires.

Those wire are very long, maybe should be shorter?

The is just no really easy way to wire in pots.  Guitarpcb used to sell boards this way and I stopped buying them for that reason.

There's no REALLY easy way, but it's really not that HARD...   :icon_cool:

Just tedious

Not hard, definitely tedious but with the advantage that you can position the pots wherever you want on the enclosure rather than where the pcb designer thought they should go. Then again, you do have to find an alternative method to fix the pcb in place.

Totally agree. I'd also add "error prone" and "fragile" to the list. Soldering the pots onto the board makes it practically impossible to wire the pots up wrong and makes it very unlikely that a wire will break off since there aren't any wires for that. You're not *supposed* to mount the PCB by hanging it off the board-mounted pots and if I was building something to go on tour around the world with someone famous, I probably wouldn't...but for the rest of us, it's fine, actually! Honestly, how many times have you seen "board mounted pot gone bad" threads here or anywhere else? It doesn't really happen. Compared to the number of times the pot nut comes loose, the pot spins around when you try and turn it, and it finishes up twisting the wires around and breaking them off*


*...because people mostly break the anti-rotation tabs off because it's easier. If you're going to do that, you instantly lose the right to lecture me about not mounting a PCB on the pots!
