Ha ha, I call them grits, and eat yellow grits every day for breakfast. Through on a couple pieces of bacon or sausage, and some hot sauce.

Can’t make fast, complementary (P-channel) devices, thus the static power dissipation of n-channel only logic would be huge.

Should have bought a 5.56 mm, now that cheap Russian ammo is no more.

Came here to say the same. I don’t know of any computational heavy engineering software available for the Mac. Unfortunately I’m stuck on Windows for all my software.

For EM analysis, it actually helps to be “on grid” as the gridded solvers have a lot more dynamic range than gridless, like 100 dB more. Analyzing structures such as filters require high dynamic range, so adding a bunch of curved artwork w

I’m sure the same can be said of semiconductor manufacturing. My wife’s first day on the job in the clean room, she noticed the plastic ribbons on the vent above the photo resist station were not flapping. When maintenance looked into it,

It depends on frequency, transmission line with, and bend radius. A properly mitered bend will have less parasitical and radiation than a curved bend. Due to internal inductance, the currents flow at the edges of a trace, thus when you ha

Wouldn’t it take a photo plotter longer to interpolate around a curve? Seems like 0/45/90 routing would be faster to plot.

Well what about us that didn't have loans and cash-flowed it? I have saved enough cash for my kids education by not buying new cars, no vacations, etc.. Seems I am punished for being frugal. I should blown it all and let the tax pay

Sure, 0.25 Gbps, it’s not like your ISP is lying. I had 0.1 Gbps before Google Fiber came through.

Supposedly it was stolen from Africa, at the time they were flying gliders off the pyramids.

No it’s not. You are just accustomed to Chinese garbage electronics.

Yep, I know of a microwave laminate (i.e. Teflon PCBs) whose yield dropped to 10% after a certain solvent was banned. The substitute does not work worth a shit.

I picked up an Indigo^2 with monitor in 1997 for $250. Had to buy IRIX CDs for $200 in eBay, but it was a nice machine. Gave it to a guy several years later, along with several other classic Unix workstations. Kind of wish I had them now

"There was - possibly still is - a crossover group typically made of electrical/electronic engineers who knew just enough traditional EM theory to be dangerous, but not enough to know what they didn't know about GR and QM.&qu

I had your exact same problem a few weeks ago trying to get P-channel FETs and ended up with the SI2301CDS-T1-E3 which Mouser has just 143 left (which you can't believe). Same with USB-UART bridges; zip, nada, nothing. I found some Cy

Why 70, so you can ignore the millions killed by Stalin and communism?

Back in the last century, we had these levers called emergency brakes. Then they went to parking brake pedals. Now parking brakes are on a button. I want the lever back.

As a kid, I acquired three Kodak instant cameras for free, as they were near worthless. Then Kodak lost a lawsuit from Polaroid and was forced to buy them back at $40 each. I made a huge amount of money for that, as a kid.

Inductance would be the momentum of the water; reactance to change in flow. Capacitance would be the expansion tank; reactance to change in pressure.

They seem to be going for about $300 used, though considering inflation less than new. If you could have gotten a good deal, then you’d come out ahead. The price will only increase. I have a 48G and 48GX, and several others. I’d like to

People from 2020 still love the too, ha ha. I have several 35s at work and just got a Swiss Micros DM42 from xmas. Then again, I'm 50 and used these all through EE school and my profession. I have four 32sii still sealed in clamshel

It has to be cost-plus or no one would do something that has not been done before. Fixed cost is fine for something you have a grasp on production costs.

You can always make impedance measurements with a slotted line, 6-port reflectometer, or vector voltmeter if you don't have access to a VNA. My undergrad microwave professor had us learn on the slotted line before letting us touch the

Just get an amateur radio license and there are plenty of bands to legally transmit.
