  4. possible to assign multiple buttons to same function?

    Hmm, light bulb moment. I'm already fed up pressing MENU+GP to get to pages. Since I have ALPS encoders with buttons it would rock if I could use those for the gate function and have the GP buttons do their thing without having to press MENU.

    Do the encoder buttons have individual addressing or are they simply addressed to FAST and no more?

    On the Wilba  CS I believe they are physically wired in parallel to one input pin which is assigned to FAST. So you could reassign them all to the same single function, but not to separate functions, without cutting traces and soldering wires to some additional DIN pins. Probably have to add DIN too, there are a few free assignments in the matrix but not 16.

     

    otherwise I think your idea should work

  9. Rebuilt MBHP_ETH

    And then I scroll down and see a schematic. only a few slight differences.CS and RESET have 10K pull ups not present in the MBHP ETH schematic, and the MBHP ETH has an extra 100uf cap on the pin 1/2, and 100nf cap on VDDTX (bypass cap). A few resistor values are slightly different. only thing I see as a potential problem is the extra pull ups, which could be desoldered if needed, which I again am no expert and maybe they are fine to leave in....

    I'm No expert, and its hard to tell just looking at a picture of the board, but it sure looks almost exactly like the schematic for the ETH module. connector pinning appears different but it has the right signals present. I bet it would work.

  12. Anyone Using Sprint Layout for PCB Design?

    in Miscellaneous

    Posted

    I bought this a couple years ago on the recommendation of a HAM Radio friend:

     

    http://www.abacom-online.de/uk/html/sprint-layout.html

     

    I actually bought thier schematic package and front panel tool also, 49,90 Euro each at the time was well under $150 US. I like it, it's easy to use, Easy to make "Macros" (Compponents) and does boards up to 500mmx500mm so I can do 19' rack panels on one board which is the largest I'll probably ever need.

     

    The drawbacks? No integration between schematic editor and board editor, they are two seperate programs and no importing the schematic into the board and having everything rubberbanded together like EAGLE and some others. Not a huge library like EAGLE, though EAGLE has almost too much to sort through. And making new components is super easy so not such a huge drawback. Other than that I quite like it, though to date I have never had a board manufactured. No 3d View either but is that really necessary?

     

    I was using EAGLE a bit back in the day, I liked it OK but the cost for a version with Larger board size was Crazy back then. I see they have some lower cost options now, but still much more than this. I also tried KiCad back in the day and it just felt Clunky, unfinished, and wierd....Maybe it is better now nearly ten years later.

     

    Anyway, wondering if anyone else is using this and maybe has a library of midibox parts they would share?

    Hi All, so it appears we pass the 10 barrier, Im contacting winstar and raystar to get quotes from them.

    At TME they sell the displays at 28.4 usd above 10 (only yellow), someone post another vendor here that apparently they carry green, yellow and white but the displays are listed at 28.5 Euros for green and yellow and 30 euros white displays.  with 10+ displays

    this increse the price comparing from TME I hope to get better prices directly from the fabricators, I already ask for price and colors available and also if we can mix the colors for the order, as soon as I get the quotes Ill send PM with the details.

    And I hope to place the order in a month from now if everyone confirms, so get ready for this, and if more people want to get in the group buy please let me know.

     

    Regards

    Let us know what pricing you get from manufacturer directly. If the price were lower I'd be inclined to pick up a few more. I'm currently considering two SEQ builds (one custom, to stay racked in the studio,and  one from Wilba panels, to take on the road, with a BLM 16x16+X to share between them) and I've got an MBFM that would look nice with OLED! If price were closer to $15 I'd buy at least 4 or 5.  no real preference for color, I've only seen the yellow, don't think id like green, but white would probably be a great choice as I'd imagine you could tint your window and get any color you like :)

  18. SD Sockets

    It Does work. I found a 2 pack of PNY 4 GB class 4 cards at Wal-Mart....I was able to upload MBSEQ HWCONIG file through MIOS studio to the SD card.

     

    MIOS studio is acting flakey though, took way too many attempts to recognize my core (Regardless of the SD card being inserted or not), and crashed the core once, making the Green LED next to the user button on the STM32F4Discovery board flash really fast. (no Idea what that indicates). Core still works though.

    Actually due to the card size issue I havent tested, but I have no doubt it will work, I inspect the solder joints under my stereozoom microscope and they look great! well, at least they look great for my work ;) I will try to test tonight I think I have an old 2GB micro card in an old phone somehwhere, and an adaptor....

     

    Regardless it is the Card socket TK/SMASH TV recomend. looks the same as the one Smash ships with his kits.

    I bought the one recomended in the Orderlist on ucapps.de

      

    SD-RSMT-2-MQ

     

    from Mouser. It is a surface mount part but I had no trouble soldering it onto the Pads of the STM3sF4 core board.

     

    My bigger problem is finding a 4 GB SD card...smallest I've found locally is 8GB! no stores have the smaller ones anymore, Guess I'll have to order a pile of them.

  23. possible to assign multiple buttons to same function?

    in MIDIbox SEQ

    Posted · Edited by arumblack

    I figure the answer is probably yes.

     

    The explanation:

    I'm building a prototype SEQ V4 before having custom PCB's made. I want to play with it and decide the ergonomics and panel layout.

    Mostly I want to decide wether I prefer the Encoder switches to be GP buttons, or to enable fast mode as on Wilba's panel. I currently have the Encoder switches wired per TK's original v3 panel layout as the 16 GP buttons. to change to FAST I would need a seperate HWCONFIG file with the 16 SR inputs all set to FAST function. Also I could in the GP button mode have both the encoder switches and dedicated switches and see which I prefer.

     

    Honestly I'd just try it out but I still have some hardware to finish ;)

     

    Thanks!

     

    EDIT : I do realize it is a wast of SR's but its only for prototyping, the final hardware would be adjusted to paralell the switches for FAST mode if that's the way I go.

  25. Crimps for 12mm pot pins

    would these do it for you?

    Specifically this one:

    http://www.molex.com/webdocs/datasheets/pdf/en-us/0901230103_CRIMP_HOUSINGS.pdf

     

    Not sure if you need the specific crimp tool or a generic one works, if someone  knows speak up.

     

    I just soldered on to my bourns encoder pins for my SEQ prototype and slipped heatshrink on (before soldering) In fat I was finishing them up last night. I'll post a pic later after I mount them.
