  1. MB-6582 analog output

    duh
  2. MB-6582 analog output

    hmmm looking at pdf it appears you are right.  will check pcb when i get home...
  3. MB-6582 analog output

    there is a passive mix out, J70.  but pretty low level output there... you can read about it here:  http://www.midibox.org/dokuwiki/wilba_mb_6582 (currently the last item on the page)
  4. bipolar regulated supply question....

    even with 7912, you will need -14v at the input instead of +14...
  5. run the SRIO interconnection test.  if you still get 4.4v on SO, then you might have a bad pic.  If so, you might be able to restore it, but someone else will have to help there (SmashTV?), I don't remember the voodoo required...
  6. bipolar regulated supply question....

    won't work. you will get nothing at -12 with this design. you might even let the magic smoke out of that regulator.
  7. bankstick problem

    this hex is for slave sid cores only
  8. SID Interconnection Test

    i noticed this bug in mios studio as well (under windows) i used midi-ox instead.  any program or hardware that can send mod wheel will work...
  9. congrats duke, looks fantastic!
  10. Midibox of the Week : MB-6582 of JV

    hmmm another builder drills the corners.  maybe something to consider if another run of panels is done..
  11. Enjoy my Creations :)

    very nice stuff!
  12. MBHP AOUT_NG module release

    wooohoooooo!
  13. MIDIbox SID Bassline Demo #3

    i like showing 132 in binary with my fingers... *whack*
  14. MIDIbox SID Bassline Demo #3

    in more ways than one... *whack* congrats on the round number!
  15. i saw an interesting site about diy player pianos the other day. had info on solenoids and using velocity to control strike. i can find it again if you are interested...
  16. I made noise with my MB-6582

    hehe i watched this almost every day for weeks
  17. I made noise with my MB-6582

    green good! napster bad!
  18. I made noise with my MB-6582

    here's the back.  i used neutrik audio jacks with the internal thread, which looks pretty good, i think.  the feedback pots i used were 100k instead of 500k which works fine.  i mounted the expansion port but nothing is connected to it yet (soon to be Seppoman's ssm filters and who knows what else?)  the fan makes some noise so i'm gonna think about what to do about that after i play with it some more.
  19. I made noise with my MB-6582

    all done, everything mounted open to show gory details
  20. I made noise with my MB-6582

    ribbons connected.  you can see one of my pcb repairs too (the white wire on the control pcb)
  21. I made noise with my MB-6582

    i used press on DIL connectors like SmashTV sells.  this is not only way easier than crimping all those SIL pins, but also is a shorter connector and has strain relief.  note that i only use one row of the connector and thus solder every other cable line.  i shoved the 90 degree sil connectors down all the way when i soldered them which allowed me to use the top row, but it might be just fine to leave them at the original height and use the bottom row... i did use a two pin SIL connector for the power and ground pins.
  22. I made noise with my MB-6582

    i used 90 degree SIL headers instead of soldering ribbon directly to the control panel.  this saved my ass big time, when i had to trace down a short (turned out to be caused by the lcd mount, so trim those leads behind the LCD!) and also what turned out to be several damaged traces on the brd, which are thin, so i just did end runs around them (soldering a wire between the two nearest pads)  all i had to do was unplug the panel and trace away.  Wilba pointed out a great idea for tracing the LEDs:  with panel disconnected you can use a 5v line with 1k resistor to trace all the LEDs, just ground each of the 8 pins where the transistors would go in turn and touch each other DOUT line with 5v through the resistor.

    ok some photos, to be annotated later: just pointing out things i did a bit different than friend wilba. forgive me for this red-headed step child *whack* notice the drilled and countersunk corner screws. i tried 3 times to jb-weld this, each time i could pull them off with my fingers.

    on top of old smokey...

    meter rocking! way cool, tk!
