What’s on *YOUR* workbench?

Brainstorming ways to convert a huge stash of fat caps and NY caps into knobs. Got a few of the brass inserts which I can proble set with something like steelstik. But i wouldnt be able to access the set screw. Im open to using spilt shaft pots, if i can figure a way they can pressure-fit.
My janky knob solution might work if you've got access to a 3D printer. In a CAD program you make a cylinder. Put a hole in it that tapers from 6.35mm at the bottom up to ~6.00-6.10mm at the top. Print at a relatively low infill (10% ish) and it'll fut/partially crush onto pot shafts. I pull mine off with a IC removal tool if the need arises. Hopefully that makes sense.

That sounds like a great idea; tapered AND the plastic has enough give to get crushed by pot. Unfortunately I dont have access to a 3D printer,. Im hoping to purchase one sometime in the near future.
 
Nice. Is that an etch? I like the 2mm flat top LEDs for thsee uses, and in general.
They're a little more narrow beam than a lot of dome tops and you can sand them down to be flush with the enclosure. Keeps them low key when off.
Thanks - and no, thats not an etch, it's transparent self adhesive stuff.
Those LEDs you linked look cool. Here, the LEDs are just the usual 3mm ones, placed through tiny holes, no bezel.

"I say, Watson, bit of stroke of luck finding that infernal spreadsheet, what? Another case solved by sheer dumb luck after a bit more digging."


Okay so last night I soldered up a 7-resistor array with matched 10k (not that I think they need to be matched for this circuit, but I'd already done the work for a Green Ringer ages ago)...

I know, I shouldn't have used the BluTak, but it was within reach and I knew what I was in for when I grabbed it.
Didn't take much cleaning up today, just dabbed it away from the resistors, took about a minute.

After that, I scoured my confuser's 'ardrive one last time and there buried within a VFE generic general-product spreadsheet of parts...

268-10k-RC — at one end of the spread-sheet and "YD" at the other end.​

So, turns out that's a Xicon part #, here's a link to Mouser's datasheet PDF.

It's a 4 x 10k ISOLATED array. Not a lot of info about this one online.

Mystery, nonetheless, solved. Yay!
I'm off to solder up a 4 x 10k-resistor 8-pin array (using tape this time ); I might just be able to figure out which end is up, ie pin1...



Oh, I never pressed "Post reply" ...



That's okay. I'm done. It's all done, soldered up and it's a perfect shitty end to a shitty year. No LED, no effect though it does pass dry signal, so I guess I can be thankful for that. Endless frustrations trying to get this thing done, under the wire at year's end.

Twas a partial kit from VFE.The pots have no washers or nuts — this has happened to me before with VFE.
Had to drill out a couple holes on the enclosure, but I didn't bork the enclosure so that's a win, but it doesn't quite fit the B2 even though it was designed for it. I was going to rehouse it in a 1590N1 anyway
Wires from footswitch breaking off, had to drill the PCB out after the solder-pump failing to suck hard enough.
Alignment problems and F^@# ribbon wire...

Here's Sasha to comfort me. Thanks Sasha, Good Dog!

Oh. 😳

I didn't put in the PT2399. 😬

Haven't made that sort of mistake in a long while, obviously was time for a reminder. ⏰
I'll just put that in there and trouble-shoot it in the new-year...

Laudy Laudy, hallyloohyeah — it works! 😹

LED still isn't lighting up but that's okay, I'll trade that trouble-shoot for the rest of the circuit working.
Right! There's a few hours left in 2025, I could drill the N1 ... nah, gonna take my time drilling the new enclosure in the Nieu Jaar.


Wishing you all many successful builds in 2026!
