You definitely do not want to be toggling power on and off in a loud volume situation. It's overkill, IMO. The lamp should last a very very long time.

Tech Help - Projects Page / adding switch to interrupt power
« Last post by ckim715 on Today at 08:02:54 PM »
Just to double check my thought, if I put an on/off switch between the 9v socket and the pcb, I can use that as a power kill switch to the pedal, right? I have a Harbinger One and I like to keep it off until I know that I am going to use it for a song so as to maximize the lifespan of the lightbulb. Thanks!

Oh yeah.  A pic of the pooch.  Dylan is 12 weeks in this picture and his ears are cut but not pinned yet.  It's a drag to put him thru the pinned ears thing but he's going to look great and for all the attention he gets he doesn't seem to mind.  Sort of a barbaric practice though, I'd probably have passed on it had the breeder not got the process started...

No. Only if you want an LED indicator for your speed. It has no effect otherwise.

Well, "wiring in a few days" ended up being half the bloody summer but I'm back at the bench.  I'd forgotten how much work a new puppy is.

The code is in and the footswitches are wired up and all appears to be working very well.  I haven't tested midi functionality yet but I have little doubt it's good.  The wiring looks like a rats nest now, although it was all neatly bundled.  I'll get to that in a minute.  It's going to be challenging to jam all those wires in and get the lid closed so will just take a bit more planning and dressing.



My wiring issue was the angled connectors mounted to the footswitch boards.  On Marshall Arts' build his connectors had the release clips on the top, which makes it MUCH easier to unplug the connector if needed.  And in my case it was needed.  Hardly a big deal but my release clips (connectors purchased from Mouser) are on the bottom.  Even though I'd read the build docs multiple times...in my brain I rotated the wiring scheme to be upside down to compensate.  Obviously I didn't put a lot of logic to it.  Here's how my connectors (wired correctly now) look:



So all my wiring was backwards.  Turns out not to be that big a deal: with these connectors it's just a matter of inserting a flat blade screw driver into the slot that the crimp connectors plug into and they pop right out.  I had every footswitch rewired in under 15 minutes.  I had to cut apart all my neat wiring bundles but it turns out I needed to anyway.  Space under the display and on top of the controller board is a bit tight.



I should be able to reroute a bunch of this stuff around the midi connectors and over the loop 7/8 tails board (not installed yet)  Wire used here is the Smallbear 24ga and would be nice to have something with less jacket.  I really like the wire though.  I picked up some of their fine gauge RG-174 for the shielded runs to the jacks so that will help.



It was a REALLY good feeling to apply power after pumping code to the Arduino and having the display and LED's boot up to a little light show and E003

Thanks for the reply, saw that. So I HAVE to use R29?

Greetings.

Can't seem to find the value of R29 (it was an addition back in the day). Any help is appreciate.

From the docs:

There are two ways you can use an LED indicator for the Speed control.

Method 1 – Make R29 a 1k resistor. Wire the “LS” pad to the anode of a 3 or 5mm diffused LED. 
Wire the cathode of that LED to ground. This method will show a square wave output so it will blink 
on and off.

Method 2 – Make R29 a 1M resistor. Wire the “LS” pad to the circuit shown below. This will give the
LED some ramp up and down on its illumination so it is not quite so “square”.

Is it ok to leave it without a jumper if I don't want pulsing LED?

thanks
