Are MidiBoxPlus16 PCBs Still Available Anywhere?

Parts Questions
1

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 I’d like to finish the project, however I realise that the MidiBoxPlus16 has been superceded by by MIOS, etc.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

hi

i 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.

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 16F877-20

o IC-Socket with 40 pins

o Crystal: 20 MHz, parallel (not serial!) cut

o Resistors:

  - 4 * 10 k

  - 1 * 1.8 k

  - 2 * 470

  - 3 * 220

  - 1 * 100 k

o Potentiometers:

  - 8 * 10 k and 8 * instrumentation knobs

  - 1 * 10 k trimmpot

o Capacitors:

  -  2 *  33 pF

  -  1 * 100 nF

  -  2 *  10 uF

o Other semiconductors:

  - 1 * 74HC00 or 7400 or similar

  - 1 * Diode 1N4148

  - 1 * CNY17-2 or simmilar optical coupler (CTR appr. 125%)

o LC Display 2x16

o Buttons: 12 * push button switches (the things which are normaly opened

  and pop up immediately)

o Switches: 4 * miniature toggle switches

o 2 * 5-pin DIN connectors for MIDI In / Out

o 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 rectifier

o Case

o ONLY FOR THE 16 POT EXTENSION:

  o 2 * 4051

  o 2 * 16 pin sockets

  o 8 additional Potentiometers

The only thing I’m lacking is the PCB.

Cheers,

Chris

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

mate, i am a bit in a hurry to give you these infos but i think you may want to read more ucapps.de and the wiki as well as digging the forum a bit, your questions are very basic knowledge and there is plenty of info.

Also visit www.avishowtech.com/mbhp you can find a more capable PIC and boards for a very very fair price, your PIC can still be used but i d advise you to spend those 9$ to get a newer one, that is to get one which is “daily” supported on the forum and elsewhere.

Again: what are yo uplanning ot build? I mean on term of pots/buttons/leds count at least.

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?
