Summoning Wiring Gurus (weirdy pls)

[Nickosaurus]

Alright.

Wiring gurus - is it possible to build this schem:

WITHOUT the LEDs/power? Make it entirely passive?

I really don't mind about the LEDs since I won't be on stage and I want to make the wiring as simple as possible.

[WeirdBits]

Yep.








Use a mono jack for J1 instead of stereo (if you want), leave out the battery, DC jack, LEDs (D1-3) and resistors (R1 & R2). Still connect the black wire from J3 to SW1, but leave out the orange, red, and brown wires (and also the purple wire to D1). There should be nothing connected to the middle pole (middle vertical column lugs) on each switch, they're only for the LEDs, so you could use DPDT switches instead of the 3PDT's on the diagram.

Make sense?

[Nickosaurus]

Yep that makes sense. Cheers Weirdy!

If I was to make this I think I'd leave the DC power plug off. Because my 9 volt supply is + earth, I could make up a extension lead to change it to - earth but there is always the chance that it gets mixed up. 9 volts won't hurt (maybe) but still a hassle and a 9 volt battery will last a while I think.
Made one up some time ago, with out the lights and I think it would be better with the indicators.

Just my thoughts.

Everything's done - but I'm going to leave it 'til tomorrow to test. I won't sleep if I know it's wrong.

I wouldn't sleep until I knew it was right.

I've edited my previous post to add an extra diagram that overlays the layout's wiring colours onto the schematic, so you can see which wires form which links.

Also, I just did a quick resistor test with some red LEDs and the 10K was actually much brighter than I expected, should easily be bright enough for most pedals. The camera has distorted the actual colours a bit in this image, but it gives a good indication of the relative brightness/intensity. Left to right the resistor values are: 10K, 4.7K and 1K (on a 9V supply). There's room to go even brighter with these LEDs, but this was enough for the demo. So, I was wrong, your schematic's 10K values should work nicely for low intensity indicators.

You could even try upping the value of the 10k resistors to something in the range of, say, 12k to 22k if you're using ultra bright Leds with clear encapsulations on them, I've found with some super bright Blue Leds you need a resistor value of something like 33k or so, or even 47k.

Tested today and it's all perfect. No issues at all (YAY)!

[WeirdBits]

Well done Nick, nice artwork too.

[Nickosaurus]

Thanks mate and thanks for all your help too. The art is from a show called Adventure Time. Worth checking out if you're into cartoons

so stoked I finally have a clean/dirty channel
