"The whole reason X volts AC produces the same heat as X volts DC is because thats how we defined the AC voltage...
The heat or energy AC voltage is the RMS of the peak to peak voltage of the sine wave. ( note that it has to be a sine wave for this…"
"A servo is just a motor that has a feedback device.
you run the motor and witch it's position. When you get to where your going you stop.
Control can be as simple as reading the voltage of a pot and turning off an IO pin to using a PID control…"
"hmm yeah Solar flares, forgot about those, they do still cause problems, but I don't know the mechanisms.
My experience is mostly keeping electronics resistant to external noise...
The best way for a person to survive a catastrophic event is to…"
"I've been busy :P
Not sure why you think there would be nuclear power, theyd all spin the same generator or whatever.
Also why would EMP not be a problem? the EMP would still induce a huge spike in the wiring and let the smoke out of everything…"
"A auto dash board heater... What is that ? 24 watts ? Sure beats a AC 750-1500 watt.
AC watts is measured using RMS ( Root Means Squared) power which is the DC equivalent. So the heat developed with 24 watts Dc is equal to 24 watts AC
"zero advantage to using DC except in edge cases like analog signal processing ( aka sound systems etc) where the ac component can induce noise.
AC is more dangerous, but it allows you to transforn the voltages for transmission.
this makes it…"
"Sorry to say this but I really doubt you have anything worth stealing.
Unless you really have a disruptive product there isn't much someone else can't do on their own
Ideas are so cheap, I have 1000s, want a couple??
Implementation is the…"
"I have used thermocouples in the past and they are very accurate.
To calibrate at that temp you either need another thermocouple or use those melting cones for furnaces. The droop over at specific temperatures.
If you have 2 spare thermocouples you…"
