General Questions / RGB LEDs
November 25, 2016, 05:55:42 PM
Hey Guys,

So I'm putting together a Pork Barrel and on the new boards there is an LED that pulses with the rate of the LFO, which is awesome.  There is also a spot on the board for a regular "I'm On" LED.  I was thinking that it would be awesome to use a RGB LED so that it always glowed blue, but pulsed to purple or yellow with the rate of the effect.  This is what I'm thinking. I'll probably use an LED with a common cathode.  I'd put the blue leg in the positive side of the "On" LED, and the red leg in the positive side of the "pulse" led, leave the green leg out, and then which ground to I tie to? and do I need to put another 4.7k resistor in addition to the one in the board before it goes to a negative terminal since I'm having two currents into one LED?

wait... I was right the first time.  It wasn't the resistor...

Dollars to donuts you used a 330K in R4 instead of 330R.

I'm impressed!  You were right!  I'll get that switched out and report back.  Do I owe you a dollar now or a donut?
Also good suggestion.  I'll post the guitar question on a new thread.  I think that the push pulls would probably be best used as series/parallel wiring.

I just finished a LaVache pedal, but it didn't work.  It turned out that I had the transistor in wrong, anyway I got it fixed, but it still acts strangely.  First, the volume only works in the upper 25% which makes me think that I need a new pot.  Anyway, when I play hard, it makes a terrible crunchy diode static noise and also the volume is always less loud then when bypassed.  Anyone have any ideas on what else could cause me this kind of grief? 

On a separate note, I am also wiring a guitar for a friend and I cant find a diagram that gives me what he wants, and I don't have the brains to figure it out myself.  This is what I want have: 2 humbuckers, 2 push pull volumes, 2 tones and a 5 way switch.  Any ideas on that one?  Thanks in advance!
