cps Posted August 11, 2008 Report Share Posted August 11, 2008 Hi,Way back in 2003, I was planning to make a MidiBoxPlus16. I bought all the components except the PCB. In late-2003 I had to move overseas so I never got the chance to make the MidiBox. Recently, I was cleaning out some cupboards and came across the parts in a box. I'd like to finish the project, however I realise that the MidiBoxPlus16 has been superceded by by MIOS, etc.Is there anywhere that I can get a MidiBoxPlus16 PCB? Does anyone have one lying around that they would be willing to part with? Cheers,Chris Quote Link to comment Share on other sites More sharing options...
cimo Posted August 11, 2008 Report Share Posted August 11, 2008 hii don t really see the point in building that, go for a MB64 or MB64E instead, what are the components that you ve got there? Write down a list and let s see what you re missing.Let us know also what you want to do with it.Simone Quote Link to comment Share on other sites More sharing options...
cps Posted August 11, 2008 Author Report Share Posted August 11, 2008 Yes, I was thinking that it might be easier to go with the newer system.Here's a list of what I've got:o PIC 16F877-20o IC-Socket with 40 pinso Crystal: 20 MHz, parallel (not serial!) cuto Resistors: - 4 * 10 k - 1 * 1.8 k - 2 * 470 - 3 * 220 - 1 * 100 ko Potentiometers: - 8 * 10 k and 8 * instrumentation knobs - 1 * 10 k trimmpoto Capacitors: - 2 * 33 pF - 1 * 100 nF - 2 * 10 uFo Other semiconductors: - 1 * 74HC00 or 7400 or similar - 1 * Diode 1N4148 - 1 * CNY17-2 or simmilar optical coupler (CTR appr. 125%)o LC Display 2x16o Buttons: 12 * push button switches (the things which are normaly opened and pop up immediately)o Switches: 4 * miniature toggle switcheso 2 * 5-pin DIN connectors for MIDI In / Outo LEDs: - Green (MIDI-Data Indicator) - Red (Init Value Indicator)o Power Supply: - Transformer: AC (or DC) Power Adaptor, ca. 9 V AC or DC (not important), 0.5 A - Rectifier: B40C800 - El. Capacitor: 470 uF - Capacitor: 330 nF - Voltage regulator: uA 7805 - optional micro-fuse for 1 A with mount. Connect it between adaptor output and rectifiero Caseo ONLY FOR THE 16 POT EXTENSION: o 2 * 4051 o 2 * 16 pin sockets o 8 additional PotentiometersThe only thing I'm lacking is the PCB.Cheers,Chris Quote Link to comment Share on other sites More sharing options...
cps Posted August 11, 2008 Author Report Share Posted August 11, 2008 I have a couple of other questions too, but I'm not sure where to post them:1. Is there a MidiBox64 section in the forum? I couldn't see one.2. Is there any info available about connecting the various modules together? I'm not clear about how this is done. Are they connected with ribbon cable?3. All the tutorials I've found for the MidiBox64 use a single PCB. Are there any more recent tutorials that explain a build using the modules?Cheers,Chris Quote Link to comment Share on other sites More sharing options...

I mean on term of pots/buttons/leds count at least. Quote Link to comment Share on other sites More sharing options...
cps Posted August 11, 2008 Author Report Share Posted August 11, 2008 I've got all the parts (except the PCB) for the old MB16 so I'd like to build the MB64 with 16 knobs and 8 buttons.I wasn't sure where to post the questions - the other projects all have their own section in the forum but I couldn't see one for the MB64.I know there's plenty of info (which is great!) but I'm not clear about where to post MB64 questions. Where do I post them? Quote Link to comment Share on other sites More sharing options...
