    Getting my learning on

    Find a version of Spice you can run on whatever screen appliance you’re bringing, or at least some tutorials on circuit simulation.

    Passinwind Open Source Hybrid Filter Preamp Builds

    Still playing around with the v2 though-hole based pedal, here's the most recent try: https://forum.pedalpcb.com/threads/inventory-builds-player-hater%E2%80%99s-ball-2025.26502/page-30#post-348609 And then the bass in post #33 got a new body and a three way Q switch:

    Very high soldering temperatures and components/boards

    FWIW, I’ve come to prefer 0.5 mm solder for both through hole and the relatively larger format SMD parts I mostly use these days. 0.015” = 0.38 mm. and is readily available, and I’d probably prefer that for 0805 and SOIC parts, but I get Bro Deals on .020/.5mm solder so that’s what I use most...

    Wire Wars

    I own around a dozen Hakko tips and change between my two primaries at least a few times a day if I’m working on any sort of extended project. I do have another tip reserved just for tinning wires, but one of my primaries works just as well for 22 or 24 AWG silicone wire, so I reserve the...

    Wire Wars

    The fumes are very toxic and not compatible at all with my particular health issues. And in my case I just make the PCB holes the right size for the wire I'm using, which took a little tweaking but hasn't been an issue for years.

    Wire Wars

    Nothing will ever get me to voluntarily use PVC insulation again, but vive la difference! ;)

    Wire Wars

    No idea, but manual tinning had been standard for me for over sixty years, so I never even think about it by now. More of a hassle with thinner gauges, but my default is 22 gauge for my own designs, which are 98% of what I build.

    Wire Wars

    This is the best hand stripper I’ve found for teflon: https://www.markertek.com/product/pal-1113/paladin-1113-stripax-pro-6 You can find used ones easily enough, but the carbide cutter replacement sets are still $$$. And they do wear out fairly quckly, I think my 22ga. cartrridge was only good...

    Ashly SC-50 clone

    I just took took a look in my ancient folders and found the schematic that Ashly owner Bill Thompson gave me during a factory tour in something like 1979. But then I also found one online here: https://audioschematics.dk/downloadus/schematics/outboard/

    Ashly SC-50 clone

    Try emailing Ashly tech support, historically they have been great about freely sharing schematics.

    Acoustic Preamp Design - Preamp & EQ

    I did it that way for my PEQ/HPF pedal which uses a Traco DC-DC brick as well:

    Acoustic Preamp Design - Preamp & EQ

    Very nice job do far! I almost never breadboard either, LTspice typically gets me plenty close enough within two build cycles for the type of stuff I mostly build. I’ve posted a few original acoustic oriented preamp builds here, and have an open source one on GitHub as well.

    Desoldering Station that actually works???

    Still for sale or trade, I guess: https://forum.pedalpcb.com/threads/pace-st115-desoldering-station.20835/ Works great for some through hole things, but I rarely use many TH parts beyond film caps and board mounted pots these days. A more modern PACE station would be my call if I needed a day...

    1u half rack enclosures?

    Par Metal: Modu/HiFi 2000: If you want to go all in on front panel graphcs I highly recommend Front Panel Express in Seattle. They do UV printing now as well, but I love their old school engraving/infilling process.

    1u half rack enclosures?

    http://www.par-metal.com/ https://hifi2000.shop/site/en I’ve used both for a variety of DIY builds, with the latter you need to read between the lines very carefully but the workmamship is quite good.

    EQ Anyone?

    Yeah, that’s the current open source one. ;)

    EQ Anyone?

    I actually have a different EQ pedal in design that combines a one band PEQ and a variable HPF, using a 9V—> +/- 15V Traco power converter chip. It has plenty of headroom to drive any power amp directly and my primary projected use case is FRFR powered speakers. I hope to add it to my open...

    Old Solder

    285 rosin is still pretty active, and a new spool like that would be $$$.

    Old Solder

    Yeah, I have a spool. Less shiny joints than 63/37 w/ type 44 rosin, but also a slightly lower melting temp. Mine came in an expired lot from a friend who works as a tech in aerospace applications. You can make it look shinier by using desoldering braid on your joints, which I tend to do for SMD...

    Jlcpcb and tariffs

    Some of my OSH orders are under $1 shipped, I usually try to at least double or triple up in that case to hopefully make it a little more worthwhile for them.
