To answer your question about heat in resistors vs transistors, if the transistor is being used as just an adjustable resistance, heat loss/efficiency is...
used a switching regulator before (although copied direct off a web circuit) and also the lm317T (which is one in a little package but that one ain't that...
I like this idea with the cap. It would be interesting to measure the currents, before and after installing the cap. Apart from that, there are also special...
Yeah, I like the cap solution. I'll make one up and take it with me when I travel back there next time (I guess I can expect my checked luggage with *that* in...

... Upon conducting a VERY brief review of 'hard start kits', it appears all they are doing is increasing the value of the start capacitor. But the motor has a...
Did you solder resistors directly across the + and - battery rails, effectively lowering the battery voltage? This method depends on the internal resistance to...

Hi all, anyone know of software that can be used on a network, and that can organize jobs and projects, and track clients and have multiple alamrs for each...
My idea wouldn't be a good one, but it might work. You can setup a SQL server (and store multiple info.) and make something else so that it can search in the...

No I soldered the resistors in place of a 4th battery in series. and I approximatly reduced the losses by 50% because a diode with a forward voltage around 3...

The short answer is...you might get away from it for a while. If the BIOS can't resolve the address to write the data to, chances are something bad will...
