Re: A Thought Experiment - Thermoelectrics and Cars

Try the same idea only passive... in effect, just replacing the rubber hose with copper would make the hose itself a more efective radiator of heat. Maybe the trick would be to add "fins" to the copper to make it an even better heat sink. <p>Who knows? you still have to get that heat from ...

Re: lightning strike

POTENTIAL is what attracts a strike, and a chimney, grounded or ungrounded has the same POTENTIAL. One way or another, the lightning will get to ground. A heavy guage wire connected to a good copper grounding rod allows the energy top get to ground with less collateral damage. As a US Coast Guard Ch...

Re: Are most people here Electrical/Electronics engineers?

I am not an engineer by any stretch. After 22 years in Uncle Sam's green card travel club (USCG) I took a job in field service, working on security X-ray and metal detection equipment in airports, courthouses etc. I get lots of great info from this BB and appreciate the time and effort people put in...

Re: Black Box

Reminds me of an incident which occurred while I was in the US Coast Guard a few years ago. The 220 VAC shoretie coming aboard a new boat was miswired with the hull being "hot" and the ground wire going to the "hot" side of the on board AC power system. Turned a million+ dollar b...

Re: solar panels and battery charging

I stand corrected. I need to read a little more carefully, I missed the low amperage of the solar panels.

Re: solar panels and battery charging

Check out Electronic Goldmine's website. they list a 150W Solar Charger Control Unit - part number G12936 in their Cat 240 new arrivals. site is www.goldmine-elec.com. It should do the trick.

Re: car speakers pop when car turned off (amplified)

Hmmm.. Could be a bad idea, but if I'm not mistaken, solid state amps can handle a no load situation ok, it's tubes that don't like to be "unloaded". I s'pose if you were concerned about it, u could use the relay to swap to a dummy load, but I'm really not sure it's necessary.
