Re: Where to buy non induction resistors

Okay, so it sounds like I'm wasting my time worrying about resistor
induction. Sound like I can just stick in normal power resistors and
get about the same result. (I tried upping my voltage with what I
had around the house and really liked the improvement but this was
just a test was cooking the resistors)

What is a constant current drive? Isn't that the same thing as a L/R
Drive circuit? (I my have just demonstrated my ignormace)
