    Weekend Update...

    By arumblack,

    Not much time this weekend But I managed to Solder up a few NEW DIN/DOUT boards. And the complication comes in the pinning of the new boards, the arrangement of the 2x5 header does not allow me to use my old 1x5 cables to the CS as wired in V3, due to the arrangement of the SR inputs. Not a big deal, off to the HW config file to do some editing (It was bound to happen sooner or later!).....
     
    Other observations on the New DIN/DOUT boards....It would be nice to have a bit more clearance to use shrouded (Box) headers, The I/O headers on the end overlap board mounting holes and the SR connections would have been too close on one of the boards IIRC. No big deal, I used the srouded headers on the SRIO chain, and normal ones on the I/O pins.

    SEQ V4 Progress

    By arumblack,

    Some progress to report. 
     
    Needed to get new ribbon cables for the new Core. One would think crimping ribbons is a trivial task but I managed to mess up two. first one I made worked fine. next two no good (one somehow had a dead short). Finally got that sorted.
    Then out to the drill press to recess the angle aluminum I had the LCD's mounted to, so they didn't end up way above the buttons. No problems.
     
    Then to finish wiring up the encoders, which I started years ago, and had all the switches and 4 encoders wired. Again no problems....well they haven't been tested yet....I'm panel mounting the encoders so I've just Soldered directly to the pins and heat shrinked over them (remember to slip the shrink tube on before soldering).
     
    Some pictures, Else it didn't happen ;)

    Finishing MBSEQ

    By arumblack,

    So many years ago I started an MBSEQv3. Life happened, moved a couple times, it sat on a shelf unfinished. So now I begin to upgrade it to v4 and finish it off. below are some pics of it after pulling it off the shelf:
     
    The case is an old rackmount Altec Lansing Mixer, I will have a new panel laser cut from acrylic You can see the 4x16 BLM's i started, one is finished the other I forgot to stuff diodes.....(they were made months apart) DOH! board on the right with the cutout in the middle is the transport section, a large jog wheel will go with the encoder shaft through the cutout. above it you can see the old MIOS8 Core. not shown are the DIN's and DOUT's.
     
    I've got a NEW MIOS32 core(STM32F4) built and testing now. Looks like the pinning of the LCD is different now so a little work there. I'll finish the Veroboard mockups to see how I like the handling and layout before commiting to having some PCB's made. I've thought about using the WILBA panel but I really want a custom solution and love the look of the SCHADOW switches I have. I have a large quantity of them but they are pulls, I hope reliability doesnt bite me in the end though they are extremely long life switches. The caps are the type that I can print my own labels and put under the clear cap.
     
    There will be a bit of free panel space and some room in the case, I am debating what to do with it. Integrate a SID, FM, or GOOM Synth? Some dedicated MBNG controls (from a second Core) Maybe some eurorack rails will fit? Just thought of that will have to see if theres enough room? I'm open to suggestions. I like the case, it fits nicely in an empty rack space I have, and is about the size of my yamaha RS7000, but will have more controls I think. I like controls.... ;) Let me know what Ideas you might have for the extra space !
