  1. Hi

    Yes, I looked at trying to reuse the 128 case. Mine was metal also.... in the end I coulnt find a good use for it so it went to the bin. They are quite big, quite heavy and not really very cool looking  :-\ unless you like plain square boxes....

    Still it was sad to throw it away as it was mine from when I was a kid....  :'(

    peace

  2. Dont you guys have the spray on board protectant stuff? Once you have etched your board you just give it a coat of this stuff and it seals it. It is like a clear silicon spray that drys solid. It also allows you to solder thru it (really nicely) then once you have finished soldering just give it a little more spray on the solder joints and all is happy. my boards are 3+ years old and still look like new. It stops the air problem and looks really shine'y and pretty too!

  3. Yeah I used just 1 of each from memory I will check later today when I get home, I put them on a breadboard to make it easy/tidy.

    yokattane? what is this from a manga perhaps? (I am a major Otaku and watch too much Anime.) Are you living in Japan?

  4. Hi

    Looks good, but make sure you have tested your components in this desgin before manufacturing the panels, i.e. exact dimensions of LCD etc.

    Also you should note that the 4 channels on the LCD are not split evenly across the width like on your design, there is more info on the LCDs like time code display etc which means the channel data is shifted to the right on LCD 1 and to the left on LCD 2.

    Sorry if you already know all this, I realise this is still a prelim design.

  5. Hi,

    Sure I have used several voltage reg's to get the correct voltage. It works fine.

    If you are using backlit LCDs you may want to put a heatsink on the 78**'s as they get quite hot.

    I use a laptop power supply (15v) that I bought from a surplus shop for about $2 it works fine on the LC (core, 2x back lit LCD & MF board with 8 motor faders.) 3A should be plenty.

    peace

    ha, that was my first post in over a year.... Im re-designing my LC now so I might lurk a bit.

  6. Hey

    Re mixing different apps via midibox link

    No problem as far as the actual connection goes (I was running a MB64 & a MBMF together) it will work just fine.

    If you want to use just 1 LCD screen to view both Cores data then you are on your own this would require you own programming.

    I just used one LCD to set-up the cores and troubleshoot then left it pluged in to the MB64 core as I didnt really need the MBMF messages on the LCD for the final design.

    Make a cheap & simple design first use it a couple of times.... your almost sure to pull it to bits and redesign it again :( Ive seen some designs in a cardboard box as a start point!

    Ive never built it but I dont think you can have Pots on a MB64E, encoders only??? You better read up on that.

    Cant help you on the sending of several controllers at once? but I'd be very surprised if it wasnt possible (once again it will require your own programming I think?)

    Most of all, have fun & welcome to the Midibox world (watch out its really addictive)

  7. Hi......

    mmmmm I also had this exact same problem with a 4x40.

    It was really easy to  solve no need to switch to 4 bits or anything like that. Make sure you have the 2nd enable line (unused) tied to ground and all should be fine.

    Hope that solves your problems?

    edit; thanks to TK for helping me to troubleshoot that one!

  8. Hi

    I am using a powersupply from a laptop its 15v and about 3a I think?

    All I have done is to build a very simple circuit on some vero board with a couple of voltage regulators to step the voltage down.

  9. Someone put a sign up on the inside of the door to the WC here at work:

    "On an average day your hands will come in to indirect contact with 15 Penises.

    DID YOU WASH YOUR HANDS?"

    (with a rather descriptive picture)

    Since this sign was put up im sure the number of people washing their hands has increased greatly!

  10. Hi

    Im having a few problems with my LCD displays they are Densitron LM4857 4x40 With HD44780.

    I have wired them up as 2x40 ie only used 1 enable line from each LCD.

    Should this be compatible with MB_LC?

    My problem is as follows:

    The characters are coming out scrambled tho, you can make out what it is spose to say but some of the letters are missing or wrong. Its really strange eg Instead of "MIOS 1.7" I get "MOS 1.7" or "MIS 1" or some other random variation. Its really doing my head in. I've rewired the core->lcd several times now. The LC application comes up on the LCD and does work its just that some of the characters are in the wrong place or are incorrect.

    Any idea's

    If my Ribbon cable was too long would it cause this problem?

    peace

  11. Hi Rowan

    Yeah I am using those 4x40s (found the datasheet thanks)

    The characters are coming out scrambled tho, you can make out what it is spose to say but some of the letters are missing or wrong.

I'll post this in the troubleshooting section again.

    Hey what are you doing with that Oban or what ever it was called mixing desk thing off Trade-me? I thought it may have made a good MB_LC clone.

    Cheers

  12. Hi

    Im at the stage where I need to design the front panel for my Mackie Control emu.

    Does anyone have a dxf/dwg file for the spacing of the channels in relation to the LCDs (2x 2x40's). ie I dont know exactly where I should position the motorfaders so they line up with the LCD display.

    Or is there an easy way to figure this out?

    peace
