Well crud. Just missed out on an eBay auction for a potbox that had all the right specs.
Got another price for a Curtis replacement pot: $45 CDN. That, to me, is just insane, considering you can go into radio shack and get a 5K pot for $2. But the standard seems to be 300 degrees of rotation, not 50.
It's looking like buying the replacement will be the route to take.
I just hate spending 5% of our total budget on a wee potentiometer
Correct me if I'm wrong, but aren't you using only 2 connections to the pot (one end and the wiper)?
So what if you took a pot with 300 degrees of rotation moved it only 1/6 of the way to 50 degrees and stopped? In that case wouldn't a 30K pot work?
No need to wait for any ICE to warm up. you can get your heat as soon as you want it.
Yes, instant is nice.
Some ICE cars have instant heat too. I don't know about the US market cars, but the last generation Echo hatch that I test drove had a honking big resistor in the heating duct that you could light up as soon as you started the car. It didn't feel "hot", but warm air did come out of the vents within a few seconds.
But man, the BTUs coming out of an ICE heater once warm is pretty hard to beat with ceramic heaters.
Even the EV1 had a lousy heater, from first hand reports I've read. (Though it was a heat pump, not a ceramic resistor.) Efficiency, efficiency...
I even took apart the Playstation analog controller to see what pots it has.
I don't think that's weird at all. One time my brother was in need of some kind of high wattage variable resistance for an impromptu project and used a piece of ham he had lying around. He had wires stuck in at different points.
Kids, don't try this at home.
