What is the best place for a hobbiest to buy small amounts of electronic parts? I am looking for an online source where I can place orders for a handful of parts at a time, which does not require $50 or more orders, or charge huge shipping fees. I am also looking mostly for parts for antique tube equipment. My typical order would likely be $20 or less of caps, resistors, and maybe some sol...

Can anyone tell me: 1) Capacitance between adjacent SO-8 pads. 2) Capacitance between different-size pads on opposite sides of PCB, spaced say 5mm apart, with standard 62-thou FR4 material, etc. Wish Altium Designer could calculate and report to me inter-trace capacitances. -- Thanks, - Win

Playing with a switching circuit, yet I seem to have made the observation that these things are fantastic for linear. Infineon SPA07N60C3, but everyone has their line of SuperJunction MOSFETs. Circuit, for posterity: https://www.seventransistorlabs.com/Images/High%20Voltage%20Bridge.pdf Intended load is high impedance, capacitive. It can easily source 5A peak though. Since the lo...

God DAMN look at how some Conservatives went up to bat for the "free speech" of this attention-seeking sick kid-toucher because he learned the right corny lines to say. The spin-job on this one which will likely be along the lines of "well he's actually your guy because gays are predators and that's what the gays you support do" is going to require a rationalization of such epic propo...

There is supposed to be one of the Mesa guitar amps that uses 12 power output tubes in some sort of push-pull parallel - parallel manner. I'd like to look at the schematic, just to see how it's wired. Most or all guitar amps have online schematics, but there are 50 or more models made by Mesa, so I dont know which model to look at. Does anyone know which model this is? I'd also be inter...

So, I've been looking over a few shoulders lately and seeing Altium on screens, and thinking maybe I should move away from EagleCAD. I looked on the Altium web site for pricing, and they're one of those "hand us one of your testicles and we'll tell you how much you need to pay to buy our product" sort of companies. I just want a budgetary price for buying one seat in the US. Anyone ...

So, I kinda hit a threshold in a recent YouTube video when the announcer just casually threw out "the transistor acts like a switch..." I'm kind of curious about the world proportion of transistors that operate in linear mode as opposed to being entirely off or entirely on. So a typical computer would have millions of transistors in the processor and memory and GPU and whatnot that are...
