  1. 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
  2. [FS/D] (backup/unused) SEQ V4 with TPD

    fine looking device.  Out of curiosity, how did you do the laser cut button caps?
  3. 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 
  4. 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?)
  5. Addon: MB6582 Mixer

    payment requests sent. Here is the BOM
  6. 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
  7. Addon: MB6582 Mixer

    i'll PM ppl for the ones I have, $5 a pop.   I'll post an OSHpark project later..
  8. 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
  9. Powering SEQ with USB Hub problem

    There may be current limiting stuff on the discovery board too
  10. Addon: MB6582 Mixer

    no, just havent had time to deal with this..
  11. Addon: MB6582 Mixer

    I like the feedback as well but its REALLY cumbersome to use the MB6582 with a 8 channel snake out the back.  I used a single supply with TL074 running off the 9V     
  12. Addon: MB6582 Mixer

    Correct.  There are 2 ways to wire this in, pre the jack which will just mirror what's coming out of the channel or post jack by puling the 10ks in the passive mixer so the SID pair is removed from the mix when you plug something in
  13. Time for my next MB

    Mouser stocks Vishay OLEDS which are rebadged raystars..
  14. Addon: MB6582 Mixer

    So after years one planning to do this, I finally got around to it.  Here are the results: Simple TL074 based mixer with stereo pots for each channel that fits to the existing holes.  I've got a handful of boards if anyone would like one and then I'll post a OSHpark link so anyone can get them any time. Boards:   BOM
