    What's wrong with your other post where the issue was explained to you? Making a duplicate post isn't a way to get more attention. If TK. doesn't answer after a reasonable time perhaps you could PM him. One solution is there but requires an upgrade to a newer Core.
  2. latigid on
    I've chatted with TK about an LED driver chip running SPI, the benefits would be less CPU load and more RGB resolution at the expense of slower transfer rates. I've ordered a few encoders to test, I'll probably make up a small board with matrix routing and connections to a DOUT module. As always, things get a bit more complicated when you have to route up a control surface PCB with 16 of these on :).

    Normally DINs/shift registers are configured in the ASM file before building a new hex. I can't answer about activating AINs; it looks like MIDIO V2 doesn't support them and it would be a custom application. If you're unable to write new software, maybe you can try with a 32 bit Core module and V3?
  4. latigid on
    I see where you might be confused: it looks like the IO app doesn't have codespace for AIN, but the later version (V3 as John mentioned) is only for 32 bit cores. V2 was for the PIC: http://www.ucapps.de/midio128_v2.html Does that make more sense?

    Hardware side: there is no AIN module (well, there is AINSER and the old AIN64), just the AIN pins. Can you explain or post a diagram of how you're trying to connect the pots? Software side: I don't have experience with these MIOS apps, but maybe you could try to upload MB64 to test? http://svnmios.midibox.org/filedetails.php?repname=svn.mios&path=%2Ftrunk%2Fapps%2Fcontrollers%2Fmidibox64%2Fsetup_midibox64.asm

    Once I've verified the PCBs I'll organise the shipping, upload the BOM and build guide and order the cases. At the moment we're still on track for "in time for Oktoberfest." Looks like all of the PCBs are spoken for (will finalise orders next Monday), but I'll bump you to the top if you get a case as well because it makes it cheaper for me. Also, (as I've already said) you'll be hard pressed to get an enclosure for a better price because just the front panel will be dearer than the whole case and you still have to add shipping! Anyway! We move forwards and I'm glad for all of the interest. It's been a long run so far and it'll be great to see more BLMs in the wild.

    Sent a PM

    I prefer to sell PCBs to those ordering the cases, but I'll let you know.

    If you're getting bizzare results from J5 after enabling AINs, don't forget any unused pins must be jumpered to ground.
  11. latigid on
    Depending on how I go with illuminated encoders it could be a lot more!
  12. latigid on
    Soon! Please let me test the new batch of boards to make sure everything works properly. All going well it should be a week or two.

    Pricing might be about $3 each if I ordered 1000... not sure if that's different enough from Sparkfun's price of $3.5-$4.
  14. latigid on
    The clear Waldorf? Not sure! Apparently they are exactly the same as Sparkfun's version. Bourns also make one which I have. EDIT: looking again these are T18 spline shaft, not what we want! Here are the Bourns pots (not encoders) which I imagine would be fairly similar. http://midibox.org/forums/topic/17669-awesome-parts-for-midibox/

    I'm considering a bulk order of encoders from Top-up. I think I can do a much better price than the ~$5 most shops seem to charge! They have a common anode RGB LED inside and a switch with 5mm travel. I think the 16 mm D-shaft with 24 detent/24 pulse would be best. They would probably work very well with the "Waldorf" clear knobs. http://www.top-up.com.tw/front/bin/ptdetail.phtml?Part=EC12PLRGBSDVBF-D&Category=337107 If you're interested, please reply below with quantities desired.

    Your quickest option will be to hit up ilmenator for an SCS PCB: If you go for the STM32F4 Core it has an SD card onboard. And if you wanted smaller/non-standard MIDI connectors (e.g. miniDIN) it might be an idea to create a dedicated PCB for this. The MIDI in circuit requires an optocoupler but it's very simple.
  17. latigid on
    Quite possibly, I'll let you know.
  18. latigid on
    Number of spare BLM/miniCore PCBs: 3 If you want cheap shipping and a cheap case, please let me know by, say 15.09.2015. Obviously I'll have the PCBs until they're sold, but I will only order the number of cases I have payments for. I'll have to consider the interest for another run (not looking likely at this stage), but let's see.
  19. latigid on
    Heh, again it's an 8-pin connector! This is the one I've bought for my cable: Mouser: 523-T3504-001 It's very nice, but a bit pricey. And with the above mentioned DIN-8 ;) socket, you have to remove the screw collar to get it to mate properly :roll:
  20. latigid on
    Eventually I found the correct one on eBay: User: lyn3009 http://www.ebay.com/itm/2-x-8-Pin-DIN-PCB-Sockets-Audio-069-/121655155694? (BTW, 8 pin connector!)
  21. latigid on
    Heh, I see this is more about the LED ring but it's still interesting to see the RGB encoder...
  22. latigid on
    I would say that we don't know how it will work until somebody (i.e. me) tries it. You have 256 colour levels with RGB LEDs but only 16 with the LREs, although you do have a positional indicator. Remember that exact values can be read out on the associated LCD. So hopefully I have some time to design and test after the BLM is out the door. Interested to see what you come up with, both in terms of electronics (see FantomXR's work above) and also the "engineering" side (panel spacing, getting the light through etc.).
  23. latigid on
    You mention "affordable" as a main requirement, which will mean something different if you are Mr. Oizo! Something you should realise is MIDIbox is a cool way to get custom hardware, but it's not necessarily going to be cheaper. I've seen many grandiose plans never get past the design phase because they are a bit too ambitious or they realise it will cost $$$. But it's certainly doable! Seeing as you have the Behringers already, you might be able to test the concept of merged data streams with a Core 32, which supports at least 4 MIDI ins and outs. Are you good on the programming side? I'm sure you could mess with the code to process the data however you like, including sending custom sysex streams if needed.
  24. latigid on
    I can't remember too many truly massive NGs during the past couple of years, but this was certainly done in the early days of MIDIbox. I would say if you really wanted modular blocks then house each in its own case and send/receive the data by ordinary MIDI. You could then have a master box which merges all of the inputs and sends out the data over USB. For this you would need one Core module per box, and an 8-bit one will do the job just fine. It's possible to send out balanced data signals via the line driver/receiver boards but MIOS works in a chain, not a star. Having multiple Core modules means just one chain per box, rather than multiple line drivers (which is untested as far as I know).
  25. latigid on
    I believe that s/he is asking if somebody will develop this controller on commission, I can see how it might be done but I think the cost would be quite high. To OP: what are you willing to pay? I'm not signing up to build it :), but just to get an idea of how much you think it's worth. My guess is that it would be more than you expect. It makes more sense to arrange encoders in multiples of 8 as that's how the shift registers are connected. I can see groups of 2x4, meaning you might get away with PCB mount on many small boards. The button pads are trickier as they must PCB mount, then you have to work out how to secure them. And I'm not sure if there's a MIDIbox application for force-sensing resistors or piezo elements, you might need to search the forum a bit. The case would also be quite pricey, it might be better to first pick an off-the-shelf model and design around that.
