DIY: OT Pickup Machine footswitch (now with final pics!)


hi thanks Markel will double check it all… going to revisit tonight and use a standard midi keyboard to setup and test the OT before I try again with the wirey hell that is my test rig… cheers G


Thanks to @qlamerand and @Markel
I have made my pedal… even made myself an enclosure… dusted off the MIG welder had to use plenty of black paint to cover my shameful welding…

I had to everything… I used an arduino nano… was so cheap! although very tiny… only powers off usb… first I breardboarded and learned the method… Its a very simple circuit thanks to the @qlamerand code… its really good … enjoyed the fact that it only had 2 resistors… I had these in stock from a previous build so was just a matter of buying the arduino, midi port and switches… I found those on uk ebay for £9.99 for 5 of them so happy…

Don’t look too carefully at the welding…

Pushed too hard with paint pen so it splurged everywhere… oh well…

Worked awesome implemented the “preset” code with debounce… works a treat…

thanks again!!! let me know if you have any other ideas like this guys!!


Awesome! Well done :slight_smile:


Great job, it looks very nice!


@qlamerand @Markel thanks guys for making this post and giving me confidence to carry it out… really excited about using it!! been so intense making it … hoping that i can get some interesting results from the OT


Inspired by this thread i’m busy building my 5 switch version. Pictures will follow when ready!
I’m using some old cheapy switches that i had, and building a simple case from 4mm MDF board.


hell yeah !!! let me know if you need any info I will help!!


My result with some small switches (hope they stand multiple foot-presses) and a case with 4mm MDF board:



I used qlamerand code, thanks, great work and nice code! (I made some small changes to the order of switches, and my switches are standard on).


Thanks! As you see it worked out nice!


loving the symbols on the board to show the purpose!! thats a neat idea!! great work and didnt take you long either!!


The planning and gathering of materials took some time :wink: but indead, assembling and the rest was relativily fast. Yeah i like to know what the buttons mean; i used some permament markers.


Maybe i give it a bit of paint sometime, but for now i just play some time with it and see if i like more buttons on it.

A future upgrade with some LEDs would also be nice: one for power, and on for MIDI activity.

But first: play time!


make sure you share that!! I was thinking a power button too as not sure how these arduinos like being powered all the time!


I will!


No problem i think.


good to know… was worrying as mine sits in that case and only know if its power if usb cable is connected… but a little LED and power switch would be perfect… not sure I want to retro fit anything now it’s all secure inside there!! enjoying using it… I did a full evening with mine and find the pickup machine is going to take some time to master!!


Same here :wink: and indeed the PU’s need some practice. But now with hands free! Have fun!
