Calling out to Weezard for LED advice

[khyberkitsune]

When two or more conductors are in proximity to each other, altenating current in one may induce a magnetic field which will impinge on the second conductor.

Now when current builds up in a restricted area along the surface of a conductor (such as a masked trace point for soldering,) AC resistance builds up at a rate which will approach the square root of said frequency. The loss built up from the resulting AC induction will send eddy currents throughout the conductor, which can cause damage to DC-based semiconductors, such as diodes, or computer processors, as the circulating current surges through the DC component and stresses it out, thus causing early failure.

And I don't give specifics because I don't give away my designs. It's that simple.

And I've built my own HAM Radio, thank you. Even cut and wound my own quartz oscillator.

i should throw away all these full wave bridge rectifiers

Maybe the capacitor makes it a capacitive circuit? I dont know. Seems like it would be a good way to handle induction though, with the opposite. I'm going to look into it more later.

In the meantime I'm just going to melt a faraday cage and use that to make traces to run the AC. Should take care of that induction problem.

5k pot in parallel with 1 ohm is almost an ohm

go figger

the 1ohm gets all the heat right?

nm i am dumb

I'm still trying to kindly rewind my old quartz oscillator.
Cutting it to size is playing hob with my cheapie, RadioShuck, diamond saw.
And it tends to not wind, when I wind it.:error:
Maybe it's too cold.:i feel stupid:

Can I borry da loan of your Faraday furnace?

Seriously Khy, :wtf: are you smokin'?
I think I want some.

Aloha ya'll
Ya made me grin tonight.

hey Weeze, if you have a minute...



That dimmer is wired on the load line of the regulator before the LEDs? Found them on ebay but the sellers arent real heavy on the specs or info.

[mx4intx]

There are different voltage models and Im not sure how they work.

[mx4intx]

Ah PWM dimmers. The 'ol on-off. Their input is the output from the, in my case, LM317? Then the output of the dimmer right to the LEDs?

PWM dimmer switch for 12v DC LED and panel lights 6 amp - eBay (item 140506143103 end time Feb-27-11 05:30:27 PST)

PWM Dimmer switch for LED lights, 12v DC

Found that. Nice price too. Specs look awesome. I'm buying one.

I'm not smoking, actually. I've been sober for the past two days.

Also, if you want a RELIABLE rectifier, rip one out of a car alternator, mx. You can't kill those things practically.
