Could AI ID a particular "Low Class" look? Absokookely! Probably spot a tRUMPin a mile away. Use it at bars, etc. to eliminate the bouncer.

Daimler and others already pointed out that the battery upon which Tesla's e-Semi is based does not exist. Tesla isn't just hoping a better battery will appear, however. They have good information on it and it isn't all that insider: http://www.businessinsider.com/new-discovery-could-be-death-blow-to-traditional-lithium-ion-batt eries-2017-12 https://www.theguardian.com/environment/2017/dec


Full wave rectified source for DC motor

I need a sanity check - I think I understand, but there's doubt. If I rectify AC with a bridge and use the full-wave output to power a DC motor, it's not the same as using "pure" DC. There is an AC component to the full wave. (The motor is a brushed PM if it matters.) If I take the Fourier series of the 1/2-sinusoid and consider each component separately & then superimpose them, I sh...

Earlier last year B-H dumped airline stocks because no one was calling up for a loan. Buffet/Munger figgered that if the executives had no faith in the industry . . . Now we found out one of the world's most successful serial entrepreneurs was ready to throw in the towel on the hard to enter vehicle market. Musk had no faith or found no joy in Tesla and was going to unload on Apple. Cook c...

I don't want to have to be there to turn on the cam. Instead it needs to be turned on by a relay. If necessary I will invade the flip flop on off switch but I'm pretty sure they have figgered out a better way. Bret Cahill

The sealed-up-in-plastic power supply comes with the plug, 110v U.S. or 220= v EU. On a 110 v AC U. S. plug the output appears to be 110 v DC and 220 AC on a = volt meter. The LED part of the rope light plugs into the output of the power supply. = It looks like two rails go the length of the LED section which can be cut e= very meter at a marked location. Some LEDs can burn out while t...

I built an alarm circuit from a book I bought called Make Electronics by Charles Platt. https://drive.google.com/file/d/1NxvKdZCqykuSjBvPVoWz_MEMhKYMMz9E/view?usp=sharing The said circuit produces a siren type sound on a buzzer so I added an led through a resistor, a 10k pot and a LDR. I then connected the centre pin of the 10k pot to pin 2 on the top IC555 shown on the schematic ...
