Needless to say I'm back on the case now and have spent an hour or so thinking about the physical implementation of my controller. I've ordered what I hope will be a suitable instrument case and whilst I await Monday's delivery have put some thought into the front panel layout. The panel is 134mm x 367mm (5.3" x 14.5") which seems to be about the right size for all the controls I will ever need.
|The Mark II panel layout, now with deleted buttons!|
This design gives me eight multifunction encoders that can be assigned by software to anything I want. Each encode has a built in push-switch which can act as a shift function, potentially giving me 16 encoders. I feel sure that will be quite sufficient!
Internally, there won't really be all that much beyond the front panel controls, the screen and a bunch of wires. I think there will be more than enough room for these items:
- Arduino Due Control processor, with Ethernet controller
- Arduino Due I/O processor
- Four port Ethernet switch
- 5V power supply unit
- WinKey or similar and sidetone generator
So I now await the arrival of the instrument case on Monday to finalise dimensions and build a full-size mock up with bits of cardboard. There will probably be a few more iterations along the way but eventually I'll produce a PostScript cutting file and take it to a local mate who has a CNC milling machine with which to cut the panel. My plan then is to have the panel painted at my local vehicle paint shop and silk screened with appropriate legends for what should be a reasonably professional result.
Somehow I just know that all this is going to end up costing me more than just splurging out on a Maestro but I think I'm having more fun this way!
