    What's on the workbench?

    Hey Bob. I know it's usually just once but any chance we get another 25% off for New Years for those slack jaw hillbillies that slept through the last sale? Asking for a fellow troglodyte.

    Drill measurements for 3PDT breakout board

    Gotta power the LED but I think Aion has pads for that. I would advise against mixing daughter boards between ppcb and Aion if you e just been doing kits. They each have their own way of doing things. It's doable but odds are you'll end up in the troubleshooting section before it's over with.

    Half-Assed Fume Extraction

    Ive thought about getting the WEN 3410 Walton's 5 and Dime has it for $115 currently. It's 150 direct from WEN They have hepa filter units too. Not sure if they have hepa filters for the 3410 but I'm betting 1 micron is enough for most use cases Edit, these are sold under a few brands. Grizzly...

    Random pix

    I failed Art 1 in high school, which I didn't even have to take but did because I wanted to and was fairly artistic. Our midterm was a watercolor piece. We had to watercolor underwater sea life. I didn't want to water color fish. I asked to do something else. Denied. So, I watercolored and...

    Adding an external speaker Jack to a combo

    Why not use a 2 pole switching jack? (Insulated/isolated) I don't know that I've ever seen a single pole switched on an amp output. https://www.parts-express.com/Rean-NYS2122-1-4-Mono-Jack-Switched-092-120?quantity=1 At 5-15w, this style should be good. Though, I like speakon connectors. A lot...

    Audio simulator?

    I've looked a bit into max msp and there is a addon called oopsy that will send gen~ to the seed. You could build in max then export to the seed when ready, I believe I haven't seen what the limitations of this are. Haven't messed with max in 10-15 years. Was just looking into it out of...

    Super Heterodyne Receiver clicking sound

    Do the root or glide switches change the ticking, either in audible frequency or rate? Any other controls make it better or worse? Also, cmos chips are particularly sensitive to ESD so use proper precautions.

    Dont believe so. Makes me think something is off in the feedback network

    Maleficent mids: mids control issue?

    Also, make sure the dual pot isn't shorting to the pot above it or the PCB/components

    What's on the workbench?

    I'm I the only one that hopes the schem is completely different than the one assembled from screen shots? Just for the sake of chaos.

    Silismile external transistor bias trim pot

    The resistor would need to be in series with one of the wires to the pot. You'll have to do some work to find the value. Install the pot as described. Find the minimum position on the pot that's usable. Measure the resistance between pins 1 and 2. Then do the same at the maximum position that...

    Silismile external transistor bias trim pot

    Yes. If you look at the schem, 2 and 3 are shorted on the PCB. This is wiring it as a variable resistor. You can just strip a bit more wire feed it through 2 over to 3 or vise versa. I would add resistance, and maybe drop the value of the pot if the resistor is large enough Otherwise you may...
