In this OP you are going to see much hypothesization, don't read it if you don't want to. A year ago give or take my hearing was so bad you might as well email me, I mean from two rooms away. When I listened to my stereo when the rest of them left at a certain dB the sound came clear. It was as if my ears opened up. Well now tonight at 4:00 AM it was very low. I could understand the words ...

Electrospinning is an interesting technique for making nanofibers. We used +15kV on the needle of a motorized syringe pump and -4kV on a collection mat = 19kV total. The electric field pulls off a thin stream of molecules, which landed into a random mat of nanocarbon filaments. My RIS-769 instrument could be adjusted up to 25kV, but less seemed to work better. Here's its first resul...

Is there a way to extrapolate this D flip flop-based/XOR modified sine-wave generator to be a little less "steppy" using a couple more flops or XOR gates? or provide outputs of different phases? I was thinking about a thing using the TinyLogic series flops/gates to clock it very fast.

I think this is right. It was a minor brain sprain, after the banana bread and rum. https://www.dropbox.com/s/r6vg4fmnnwgk96y/30_60_120_3relays.JPG?raw=1 Imagine designing an entire dial telephone system with relays.

Twice, I've experienced earphones go dodgy in the same peculiar way: one side attenuates in volume. What might cause such a condition? If it's an intermittent solder joint, the sound would break, there would be a crackling noise. Instead, it simply goes soft. The type that insert into the ear, not the pods. -- Rich

I keep wondering why Germany is being misled into giving up nuclear power. Something is wrong, that's obvious. Not saying it portends something else, but it could. Of course Albert Einstein was brilliant. Germany has produced lots of great classical music. But... What the hell is wrong with them? They allowed themselves to be misled by Adolf Hitler to their near total annihilation. I'...

Gentlemen, I thought these terms were effectively the same thing, but now I'm not so sure. Taking a square waveform of uniform amplitude for the sake of simplicity, AFAIAA, if I'm looking at such a wave in the time domain with an oscilloscope and I'm seeing intermittent thickening of the vertical portions of the trace, that's jitter. But if the frequency of the wave is more slowly v...

MIT is habitually involved in some scummy scandal or other like I thought these people were supposed to be smart. "I don't want to see the Media Lab crumble due to Epstein's dirty money" why not? They throw tons of money at some of the dumbest shit like this holoprojector

So I copper clad proto-ed the grayhill rotary switch into my PD thing. I can post pics.. at 1 MHz an inch of bus wire is not a big deal. Anyway with the switch body grounded the step response/ BW went to crap. (100 k ohm FB) When I floated the switch with my dremel, and I got a nice improvement in BW ~400 kHz to 800 kHz (I wasn't looking at the step response at the time.. and BW me...
