7 pin midi, bi-directional including phantom power
Found that one on eBay, it's 40x2 and was about 15€. https://www.ebay.de/sch/i.html?_nkw=hd44780+40x2
Shopping list:
- Arduino Mega ( $6.56 )
http://www.ebay.com/itm/401036224315?_trksid=p2060353.m2749.l2649
- DIN Female Jack (7 pin if you want power supply from Midi Cable) ($0.99)
http://www.ebay.com/itm/272139554632?_trksid=p2060353.m2749.l2649
- LCD display (I’ve bought one with a keypad that I may use in the future) ($2.56)
http://www.ebay.com/itm/Keypad-Shie...emilanove-UNO-MEGA2560-MEGA1280-/221849044117
- Stomp Pedal Momentary Switches ( $2.54 each)
http://www.ebay.com/itm/Guitar-Peda...Effects-Push-Button-Foot-Switch-/400914113943
- 220 Ohm resistors for the MIDI Output and for the LED’s ($1 for 100 units)
- LED’s ($1 for 50 units)
Minimum cost:
Arduino Mega.................................... 1 x $6.56 = $ 6.56
LCD Display...................................... 1 x $2.56 = $ 2.56
MIDI DIN Female Jack...................... 1 x $0.99 = $ 0.99
Stomp Pedal Momentary Switches... 15 x $2.54 = $ 38.10
220 Ohm resistors............................. 17 x $0.02 = $ 0.34
0.5 mm LED...................................... 15 x $0.05 = $0.75
Case................................ Free, using imagination
Cable................................ Cannibalized from scrap LAN wire
TOTAL COST .......................................................$ 49.30
How long does this take to build? THAT's where the hidden cost is
True, but building your own controller allows you to do whatever you want, since you are in control of the sourcecode. I built features into mine that I've never seen on any other controller. That level of control is addictive I'm telling you!How long does this take to build? THAT's where the hidden cost is

But since you are right and building one by yourself I think it's important to follow the open source philosophy here. Everyone who builds one by himself should release everything (source code, drawings of the casing and wiring, hints, experiences building it etc) so others who might want to go into the same or an equal direction don't have to start at zero.
I myself got a bit delayed with releasing everything, but I'll manage to do it this year, promise (hope I can keep it!). I'll most probably change my code so it works with the II aswell (I wrote it for my Ultra), which shouldn't be too much work.
I forgot to take a photo of the inside (wiring etc.), but had to disassemble it again, so I can't take one now. What's left to do is to varnish the case, connect the top and bottom steel plates and screw it all together. As soon as it's finished I'll start with documentation, polishing the code, replace the german comments with english ones, replace the german variable names with english ones (right now it's a mixture of both
. I'll show you pictures and maybe a video of the completed thing and then, when the rest is done, I'll release that too, most probably on a platform like github.7 pin midi, bi-directional including phantom power
With the bi directional midi data, is this identical as to what come out on the Midi out port of the Axe FX. I am trying to read some sysex data on my own Arduino project use the Axe FX midi out but struggling. To summarise my question, does the sysex data (preset names etc) appear on the midi out port or only on the bidirectional pins of the midi input on the AxeFX ?
