Wolf, As an aside can you tell me about the 3 wheel solar car you worked on. EVA/DC has restored the MIT Aztec solar car a '94 competitor in the Tour de Sol...
Greetings EVers: I am too poor to buy Lithium Ions for my 1992 Solectria Force. At least I can read and dream.? Here is a link to an interesting article: ...

1994 Solectria Force - Legal for the Streets ! I just got my license plates for my car. I have begun the battery break in regimen. I'd just like to thank...
Wolf, Thanks for the info. Much more impressive when this is done by high school students as opposed to MIT engineering students. Although the age difference...
Our E-10 had this a while back and our Force just recently developed the same thing. There is a spot on the accelerator potentiometer that is where it sits...
Greetings: A long time ago I replaced the potentiometer (POT) in my 1992 Force. I removed the POT and found some numbers on it that corresponded to the...
Solectria once told me that the source for these pots was critical, so I would suggest using the manufacturer and specific part number on the pot. BTW, it...
You can probably pick one up at a good electronics surplus store. They tend to have higher quality and good prices. If you are in the Bay Area, consider...
Bill: Linear vs non-linear (logarithmic)? can be determined with an ohm meter. 1)? measure the resistance between the two outer terminals. (say for example it...
logarithmic pots are also known as "audio taper" or "attenuator". :) Wolf *wags his tail* www.wolftronix.com...

What is required of one of there, from an electrical design point of view? There is the input voltage range (which might be 140-180), the output voltage (is it...
If you need a DC-DC convertor, any modern switching power supply will work (even a computer power supply). There is a bulk capacitor on it (it will be the...

Am I hearing you right? A computer power supply can take 140-180 input voltage and supply X amps at 12 volts. Maybe enough to run the lights? Bill S ... ...
Yup. http://www.wolftronix.com/DC_powersupply If you want quick and dirty, then just hack off the end of a line cord and wire it directly to your battery...

How much power were you supplying to the load? My lights draw 0.47 amp =~ 8 watts. It would be teriffic if you could keep a battery charged by tweaking the...
Bill: Wolf is correct.? There are other power supplies that produce strictly 12 volts and that can be adjustable to 13 - 14 volts.? They easily provide 10? -...
I was just curious about what is required of a DC/DC converter. A friend is doing a conversion, and he is adding a battery. My Force does not have a battery. I...
I just discovered the model controller I have is rated for 216v. It's an AC230 . Nominal voltage 180-216 . Safe operating range says 150 - 250v. I have a...
The one in my truck is rated at 12 volts, 31 amps. The only reason I would think that you would need a battery, is if you under sized your dc-dc convetor...

Steve: I have two Zivan NG3 chargers in my 1992 Solectria Force.? They have an over- temperature limit of 55 degrees C.? If the ambient temperature in the...
The components in most electronic/electrical devices are intentionally underrated so it may be able to handle it. But, from experience, long term over...
Do you think it would be possible with a little modification to modify one to go the other way for driving the AC motor or PS pump? I think that would mean...
You would not be able to use a computer power supply for that, it can only vary its 12 volt output +/-1 volt. If you found a switching power supply that put...
