  1. (FS - EU) MB-6582s

    in Fleamarket

    Posted

    Hey Guys.

    So the Red and the Green One are sold.

    The Blue one (VFD) I will keep for myself because I managed to repair it and fix the VFD issues.

    However I still have quite a lot of nano swinsids PCBs if anyone needs any ?

    Hey Guys...

    So over the years I have gathered quite a collection and I need some money for other projects.

    Green MB-6582 has a normal Display, Red one has a OLED and the Blue one has a VFD Display.

    Everything works fine - only on the VFD Display sometimes if you move the values too fast it will f*** up the display text. I tried for quite some time to reduce all of the noise on the voltage rails but it never turned out perfect - still happens.

     

    I have Power supplies for all of them and they come with original SID Chips or NanoSids depending what configuration you are looking for.

    I have to quit my music hobby because of a switch of interest.

    So just message me if you are interested and let me know what configuration you would like (how many PIC and SID Chips etc.) then we might be able to work something out.

    I live in Austria and would prefer shipping within Europe.

     

    Cheers,

  7. Can't change Patches on other Cores

    in MIDIbox SID

    Posted

    Hey guys..

    I have a problem with my new build.

    I uploaded the newest firmware and cloned it to the other cores without any problem.

    The cores are detected and the SID chips are playing sound.
    If i am trying to change the patches on the first Core SID1 everything works like it should.

    If i go to SID2 and change Patches it will still stay on the same Patch even though the display shows another patch.
    What could be the possible cause for this ? I guess the CAN bus must be working since i cloned the firmware without any issues.

    I appreciate any help.

    Thanks

     

  11. MB-6582 fan: blowing or sucking?

    in MIDIbox SID

    I have mine blowing out with vent holes on the bottom of the case.
    I had no noise issues with the Fan - however a LC Filtering Stage will be quite easy to implement if you find yours to be noisy.

    I use a standard 12V Fan and run it on 9V.

    I also have heatsinked all of my SID Chips with VGA Heatsinks and 3M double sided tape.

  15. Midibox MB6582 Newhaven OLED finally working :D

    in MIDIbox SID

    Posted

    Ok guys.. got it working now. Here is a short summary for those who would also like to give it a try:

     

    Upload the attached "setup_mb6582_vfd.hex"  (its the newest V2.045 with hawkeyes driver and a couple of more stopcycles)

    Solder a 47uF, 100nF, 10nF and 1nF Cap directly on the LCD (+5V / GND).

    Put a ferrite on the cable near the plug of the LCD.

    Before the ferrite put in an 56uH inductor into the cable - solder it and put a shrinktube over it to protect from shortcircuit.

     

     

    I tried it now with very fast changes in Menus etc. etc. and it seems to be stable.

     

    If you can't get it to work please also try to erase your pic and start from scratch (bootloader - mios / firmware - etc.) and don't change the LCD ID to 7 (like with the OLED) - just upload the setup_mb6582_vfd.hex.

    If its still not working i can make a copy of my complete pic and send you the hex for burning a 1:1 copy of my pic.

     

    Have a good weekend.

    Just a quick update - i got the old driver from hawkeye but i could not get it to work on my MB6582.

    Currently i am modifying the driver with a little more stopcycles and i added a filtering stage on the VFD with an 47uF, 100nF, 10nF, 1nF Cap directly going to +5V / GND.
    I also added a ferrite cable shield near the VFD and it seems that now i get reasonable output.

    Sometimes when there are fast changes i still have the display a little bit buggy but i will post the hex of the modified firmware (with V2.045) as soon as i get it more stable.

    So i would recommend to all that are having problems to check their power supply and shielding.
    If you use a switching regulator it is very likely that you have noise on your +5V Line - if you don't use a switching regulator it is very likely you don't have enough power to drive the VFD.
