I’m looking for order-of-magnitude bounds on how much Voyager 1’s trajectory would depart from a constant-velocity inertial...

Why? I'm not sure what makes a relaxation oscillator "standard", but the operating frequency isn't hard to make whatever it is. Yes...

As is the 2nd, 4th, and 5th. Typically the 3rd and 5th are higher in amplitude than the even harmonics. I believe I have this right...

I would look into resonant SMPS designs. My first guess is a resonant LLC half-bridge topology, but I haven't looked into this for a few...

I'd like to see the overlaps, perhaps a Venn diagram.

I wonder when I read these polls how many of the small response items are people just #$@^&# with the pollsters. 4% believe in shape...

Another entry in the "old semiconductors I found in my fathers stash" category. 2N2153, a Ge PNP power transistor in a (weird) TO-36...

The impedance of the motor is; Z = R + j X. You should not try to neutralise the in-phase real power component.

Some points to consider before you get too excited: 1) Thermal cycling also kills motor/generators. I once headed a motor reliability...

Winner of a participation prize.

1) Let's not confuse UFOs with extraterrestrial visitors. I personally saw a UFO, just the other day. It might have been an A320, or a...
