I'll throw my hat into the ring.

Those are a few of my own builds.

The HOWL is a TS808 clone with the asymmetrical clipping mod / LED clipping mod as an option (via the toggle)

The next one in is temolo I called "the face of the deep"

The only mod on this one is the blinking LED in time with the speed control.

I've also built an E/B switch a loop switcher.

Hello again, all. I am trying to find some DPST Relays online... but I can't find them for a price I like! I found some on Invalid Link Removed, but they are $3.50 a piece, and I need 13 of them. With shipping it comes to $50. That is more than I wanted to pay. I've checked all the sites I know of that sell electronic components, but they either don't sell them, or they are too expensive, or I can't find a price listing because the site I am on is actually intended for businesses to use to buy like 800 of them at a time.

What web sites do you guys use to buy parts?

A little background on why I need 13 relays:

I recently started playing synth, and I want to be able to play synth while playing bass. So of course I decided I wanted to get a MIDI controller pedalboard. Once I looked at the prices for this stuff, (usually over $500, much more than I payed for my synth) I decided to try to build one. I have a ****** organ in my bedroom that I haven't been using at all for at least a year now, which has footpedals. So I am using that to trigger the notes, and I bought a broken MIDI controller (M-Audio O2), and luckily enough of it works to do what I want with it. the only problem is the way the O2 triggers the notes is ****ing weird... there are two little surface mount switches for each key, and they don't just close the circuit, they add a resistance to the circuit... and you have to press them down in a certain order, or they wont trigger. You have to press down the top one, then the bottom one to trigger the note, then you have to release the top one to release the note. Now the pedals I have are just a simple switch that closes the circuit. So my idea is to buy a relay for each note (only 13 notes on this pedalboard) and have the pedals turn on the relay, which will attach resistances to the circuit simultaneously. Hopefully pressing them at the same time works and the top one doesn't have to be on first.

If anyone has another idea for getting these two products to interface with each other, I am all ears. This seams like it will be more expensive than I hoped for, and I don't even know if it will work for sure!

Well, $50 for something that has the potential to not work though... But I haven't checked mouser, I'll do that.

but I have photos of the equipment:

Side note: you can see exactly what broke on this MIDI controller from this photo. You can see the cracks in the circuit board, some keys that are above this exact location were also broken, I'm thinking they just dropped something on it, and it broke the keys and cracked the circuit board. The circuit board would be easy to fix if I needed to.

Thanks again for pointing me to mouser, but after some more experimentation, I found that I don't need relays. I can just connect the two outer poles of the O2 switches to each other via two resistors, then use the footpedal switches to connect the point in between the two resistors to the middle pole of the O2 switches.

Hooray! I don't have to buy anything else! Assume I have 26 resistors anyways... which I think I do...

Very nice! How are you painting these?

Hey guys and gals!

Just wanted to apologize for not posting much on this thread as of late, as I was a little worried how the CUP would affect me. Others still post, so I'm back in. As always, feel free to PM me if you have questions regarding builds, I love to help :)

BTW very nice builds!

So i'm cooking up a pedal design in my head and it calls for a 4 position toggle switch to choose waveforms. What I want to do is replace the toggle switch with a stomp switch to cycle through. How do you wire a stompswitch to cycle through 4 signals into one master output with LEDs?

Next I thought I would add a toggle that changes from, "step mode", where the foot switch cycles through, a rate mode with a knob for speed, and a tap tempo mode where that same switch becomes a tap button. Would this be really difficult? what would I need to create the rate? an internal LFO is something? is there another way?

I'm not good with schematics, but if anyone can provide them for any of the questions I've presented I'll try to figure them out.

thanks

Yeah, that's going to be really difficult to do. Most likely some sort of digital controller will be needed and you probably won't be able to use a regular 3PDT footswitch.

Thanks Spencer. I'm a big fan of your work.

I'd like to be able to silk screen them, but as it stands I'm doing something much more like labeling them.

I create the design and then print it on transparency film, which I then affix to the case with adhesive, and when that dries I coat it in a half dozen layers of clear-coat.

Here's a few of my latest:

Looks good to me. Seems easier and cheaper then hand painting.

Well, this part is not really that difficult to do, but aside from a bit of digital logic it also requires relays or some other switching system to be crammed into the box.

A simple digital counter chip attached to a momentary footswitch could cycle four of it's outputs on/off in sequence. Then these outputs can be used to control relays or FETs to actually do the switching. Granted it's not going to be as easy as wiring up a switch, but it's not rocket surgery either.

This. It can be done, but it is up to you whether the time is worth it. Microcontrollers can get you there too, but there may be a size/programming learning curve issue, but let us know what you do :)
