Hi everyone. Long time, no see. But I have only now got my soldering bench back in place after more than 6 months of medical and construction hell. I'mma cut to the chase: I need to make an ultrasonic white noise speaker system, omnidirectional as can be and with a frequency range of maybe...

I can tell it's fake because there's no trim pot to dial in that transistor bias

I'd start with a Peak DCA. Then a bunch of Ge Transistors to test until I reach the $100 mark.

Sweet. I may breadboard this if/when I get a bass again

Hold on there, Babalooey, who said anything about well-laid-out? I get things in a pretty grid and hit "auto route." Also, what's "dead bug style?"

I saw a bunch of videos online where people are making fancy temperature controllers to follow a reflow profile. Are you saying that's BS and I just need to time or watch it?

Well, I was going to guess 17 so either way... back to waiting until my next paycheck. Nobody buy them out of stock.

I've been listening to a lot of doom metal, particularly Boris lately. So, you know, probably DADGAD or Open E. Maybe Nashville tuning.

I've also built a Violet Rams Head, with the tone mod switch I saw on tagboardeffects. Sounds killer. My most surprising pedal has been the Parthenon. I still don't have it boxed up, but just in the Auditorium board, it became my favorite overdrive. For completed builds, I was surprised how...

From the day job. We're demonstrating how you can measure the vibration modes of a vehicle using our laser-robots.

Something Good This Way Comes Oh, how about his dad, Bob?

Son Of Suzy Creamcheese Pink Floyd

beginning to wonder if I'm the only one here who's never had a tube amp

Yeah, I could see that R16, C8, and R18 are all going to the inverting side of the TL072 op amp. This makes that stage an active inverting high pass filter. Although, I think it's actually technically a bandpass filter because of C9 being there too. This is more advanced than the rudimentary...

Order won't matter.

I played bass here and there from 2006 to 2020. I really treated it like a melodic instrument and never practiced keeping a beat. I had a Bass Pod XT and that was it. I do know that you need a good blend of mic and DI but that's it. I had just discovered flatwound when I decided to say screw...

That's interesting. Why go with different sizes of resistors and caps, I wonder?

Guys, I was converting a schematic to a pcb layout yesterday, and I was thinking about how neat/easy it would be to just have everything be SMD. I did have to solder up some mic signal conditioning boards for my grad school research, and while it was tricky at first, I do remember eventually...

I am currently an Iridium user. I really love it so far. I start most overdriven/distorted pedal chain sounds on the Punch (Plexi model) and I start slowly increasing the gain from zero. At some point it hits a sweet spot and that's my tone sorted.

Heads up, I just ordered some 5457s from DigiKey yesterday
