New DIY Bluetooth controller
My DIY Bluetooth foot controller is complete and I couldn't be happier with the results:
I bought an Ion iCade Core from eBay for cheap and pulled out the buttons, circuit board, and battery pack. My first prototype used the buttons from the iCade:
As you can see from the sticky notes, this allowed me to correlate the buttons with the Side Car app that I use to "catch" the Bluetooth messages and transmit MIDI CCs to Loopy (and ToneStack and MiMix):
I wasn't completely happy with the iCade buttons because I mistakenly activated some while stepping on others, so I bought some guitar pedal switches from a supplier in Singapore (slow delivery but dirt cheap) and mounted them in the new enclosure. The wiring/clips from the iCade work attach easily to the new switches; no soldering required!
Now, I have eight different options at my feet with my iPad.
