The components were chosen to be standard, cheap and easy to find. Using only through hole parts which can be found in Mouser, DigiKey, Farnell element14, etc...

So far I have the part numbers of Mouser, but any contribution is appreciated. You can download the part list in different formats (.TXT .PDF .XLS .ODS):

Some components can be replaced by alternative parts:
  • TL072: standard dual op-amps like 4558, 4559, TL062, TL082, etc...
  • TC1044: MAX1044
  • 10MΩ resistor(R1, R2): any value between 1 and 10 MΩ can be used here
  • 10KΩ Potentiometers (RV2, RV3, RV4): any other value can be used.

Hey guys,

First off, congratulations! This is an incredibly great idea and I believe a watershed moment for the future of DIY audio and especially digital effects. (I've thought of doing something similar many times over the past 2 years myself, but never had the time).

I have bought a kit, but one suggestion would be to offer a kit+arduino package. The UNO is pretty standard now (I have one) but the DUE not so much.

I'll let you know how I get on when the kit arrives.

All the best,

TC

Hi,
Thanks for the positive feedback. :)

I was suggested in the past to offer a kit including also Arduino Due, but so far I cannot get any special deal, so I would get Arduino DUE at the same conditions/price as you.

I am aware that UNO is much more used, so maybe to create a lo-fi pedal shield for this platform is not a bad idea, even though it cannot reach the performance of DUE.

Kind Regards,
JR

Real low-fi given 6 bits of resolution. I've just started reading all the literature here, but would this even be possible with an Uno? I know that Ardunio has given the Due audio support, but I'm pretty sure that's missing from the Uno.

I love the UNO but I would need to do some field research to check the possibilities. There are some limitations (no DAC, processor speed..) but why no!

So I've gone over the parts list and since I already own a Due and a chunk of the components I'll definitely be using this project for my Senior design project for college.

Here's a screenshot of the parts from Mouser (sans shipping if any). Ends up being a little pricey considering the cost of the Due, Line6 has a programmable pedal for $170 USD for example, but the programming tools suck, and my school has been pushing Arduino's lately anyway.

Is there a recommended Mouser part number for the connectors?

I'm not new to mouser, but I cant' seem to find anything appropriate for the PedalSHIELD.

Thanks!

Found some!

They are a bit pricey, but convenient if you're placing a mouser order already.

Search for

Mouser Part #:
782-A000026
Manufacturer Part #:
A000026

I found by making my list that once in a while it takes some creative searching. Unfortunately I've had to reload my OS on this machine since I made that spreadsheet and hadn't bothered to back it up :oops:

When I go to place my order with Mouser (or get bored at school tutoring early in the semester), and do some price comparison, I'll make a Google Spreadsheet with part numbers from wherever I happen to find them (perhaps with links).

Just check that the matting length is long enough for pedalSHIELD... I don't see any datasheet or info related to the length of the connector you are linking, but it seems to be the standard one (which may not work!)

JR made a specific topic related to these connectors. Check it out and be sure that the one you choose is long enough.
