As I've said, I don't see how "locals" can be ignorant of the risks! You don't leave your windshield exposed (lest the steering wheel and seat be too hot for contact). You don't casually grab the handle of a shopping cart left in the parking lot of a store -- and NEVER touch the fen

I tend to assume all claimed certs on products like AC adapter bricks on Amazon are nonsense. There's this apocryphal story that Amazon has recently cracked down on certs: but if so I take that to mean they put US sellers and manufacturers who do have the proper certs in hand through

Is there any way to guarantee the bandwidth available to a subgroup of ports on a (managed/L3?) switch? Or, do I have to resort to a separate switch for this?

Assuming two concentric tubes, both conductors with a field between them. Does introducing a plastic, say nylon in the field change it in any way? Direction? Field strength? Thanks, Mikek

I'm surprised no one else has mentioned this here. https://qcentre.co.kr/home This web site is often down from the high traffic volume. The visit counter is reset at 10AM KST or 9PM EDT. The long and the short of it is, they appear to have designed a material (LK-99) which is a superconductor up to temperatures above the boiling point of water and pressure of 1 ATM.

Anyone is free to answer, I just wanted Bill look at it. Running tests on the 2"x2"x 34" glass vessel with aluminum tape electrodes on two sides. The emulsion is 23% water and 77% soybean oil. The first test the water was clean, we drain the unit shake the oil to get a new emulsion and repeat the test with some small change and run again, every subsequent test we get nearly the same s

The Keithley 2001 is obsolete, so our test department is moving on to a Keysight. They'll have to add a driver into our Python library. They loaned me one to evaluate. https://www.dropbox.com/scl/fi/vv1u2r1whendlxioihoma/Two_DVMs.jpg?rlkey=y0pbb1xhjl5na4004lfjoih6 c&raw=1 Not too bad, considering that my Fluke hasn't been calibrated in human memory. I had to take six pics to get the n

I am using the portable charger on friend's house, but it's tripping the GFCI circuit. How is that possible if the vehicle is isolated from the ground with four rubber tires? The 15A power extension is fine. I have used this charger on another house before. Is the GFCI outlet too sensitive? Anyway to deal with this? Temporary bypassing the GFCI outlet?

The electric wheelchair I've automated has "issues" with changes in direction. These are a result of the way the non-powered wheels are connected to the frame. If you examine the front and rear pairs of wheels, you can see that the point of contact with the floor (which is last to change during a turn) i
