  1. dipCoreF4 and dipBoardF4, a compact Core.

    works for me :)

    Oh, in for sure.  I have clamshells for F405s to flash the bootloaders too
  3. MIDIbox SEQ V4 Release + Feedback

    Oh this is great.  This was something I wanted to add along with the new aout im working on based on TI DAC8568 (8 channel part, same as used in O_C, Yarns, others)
  4. Hey altitude how did you make you connector for your oled display in in your mb6582? 

  5. awesome to see this done!
  6. I've built a bit of experience with this and that euro module in the last year or so and been working on my own Aout in parallel and found it's pretty unsuitable in it's present state.  Namely: The bipolar circuit is referenced to the power rails and in a full euro cab, that is a VERY bad idea, massive noise ingress is the result making it useavle.  Removing that part of the circuit brings it back to very decent levels but 0-10V isnt terribly useful in euro.  Also, scaling the DAC outputs with a trimmer is a bit crude, per volt adjustments would be MUCH better (like in Ornament_crime or Yarns). My idea is to keep the MAX525s since they are available and decent parts and serial addressed but switch the analog output stage to that of Yarns or O_C (-3 to 7V or -3 to 6V outputs respectively) and port over the code for the calibration of those devices (whichever is easier).  The hardware side is covered but I really need someone who can code to deal with that end of it.  O_C is teensy 3.2 base but Yarns is STMF405 which should be very close to the current core code base.. I'll provide hardware to work with for any takers
  7. Moog case is a no go if you want stuff on the back, it has fins inside that cause problems. Ill post some pics shortly
  8. !Sold! [FS/D] (backup/unused) SEQ V4 with TPD

    fine looking device.  Out of curiosity, how did you do the laser cut button caps?
  9. One MB-6582, One Power Supply: a Tutorial

    i've done it both ways and I dont see any difference one way or another.  If I had to do it again, I'd use the 7809, cheaper and smaller. One thing I'd recommend (unrelated to this question):  DONT use the E series recoms, they are super cheap for a reason and not well suited for audio applications,  Output noise is unacceptably high 
  10. The FPGASID Project

    It would be cool if they could shrink it down to SID size, those are machine stuffed anyway so no reason not to go to a TAG programming header, 0402 passive, small as possible everything else (underneath?)
  11. Addon: MB6582 Mixer

    payment requests sent. Here is the BOM
  12. I just stuck a darkly tinted window, it obscures the depth..  There is no way to go in front of the PCB, it will interfere with the tacts
  13. Addon: MB6582 Mixer

    i'll PM ppl for the ones I have, $5 a pop.   I'll post an OSHpark project later..
  14. Powering SEQ with USB Hub problem

    I think that there is something else pulling it down, I run mine on USB power all the time when I'm flashing it, check resistance between +5 and gnd and +3.3 and ground
  15. Powering SEQ with USB Hub problem

    There may be current limiting stuff on the discovery board too
