another first timer DIY midi controller
Hey everyone!
So its my first thread here and probably like my 5th post ever, but I've been reading these community s / midi box / arduino playground etc etc for months and months and months now. Finally got off the interweb and decided to start working out my midi controller project. The Plan.jpg

So far I've gutted a Mixman DM2 Digital Music Mixer that I bought off ebay ($25.94) to try and salvage the jogwheels (No go thus far) and maybe use as a midi brain (no go, way too erratic)
Got a second hand arduino ($50), super useful (taught me many many things!) but in the end won't have enough inputs (got an UNO + kit)

This is a mockup based on what I do have/plan to get & the enclosure is still up in the air (maybe briefcase?)
big red button was for jokes, but then I went and bought it, so there's that... anyway, parts list:

  • (50% off sale) 2 x Arcade Button - Black - $2.18
  • (50% off sale) 2 x Arcade Button - Red - $2.18

Total + Shipping: $24.85

- which means so far, I only have about 60% of the parts I need

- I've also gone and gotten the usual first timer's works at a local electronics store, Soldering iron, solder, station, sponge, buncha resistors, buncha wire, couple wire cutters, 99c crossfaders, couple buttons here and there, spent $50 there

My original enclosure idea was going to be this nice thin wooden box I found at a thrift shop, but its a couple inches too small if I really want jogwheels (do I?) (k, thought about it, totally need anyway)

I believe I'll go with this (many of you may remember this instructable featured here on the blog) FBYAM08FN82OE6G.LARGE.jpg

someone's done it with an arduino mega and survived!


K, this is getting long, apologies.
Last but certainly not least:
I was going to get me a teensy 3.0 teensy3_pins.jpg $19 without pins, $22 with
but then I saw that Livid's announced an affordable brain! check it http://shop.lividinstruments.com/brain-jr/ $49, 16 digital connections and 16 analog connections.
That sounds like all I need.
If I'm wrong, good heavens please tell me.

Anyway so this is where I am now, still trying to pick a brain and not enough inputs on my arduino UNO so i'm unsure whether there's a point in starting the wiring, but if anyone has any suggestions for me, I'd welcome them and also would hope they'd help someone else (any thing you'd add to the controller? should I go midibox and scrap teensy/livid? should I get the $189 livid builder brain cause it'd save me a hassle? Have any of you successfully DIYed some jogwheels? Care to share the experience?)

Oi, that's enough out of me. thanks in advance for any input, folks!
