    In front the all black, MOS 8580, stereo MbSID with feedback mod in ZX Spectrum + 48K case (SmashTV's modules)In the back the black/alu MOS 6581R4AR, stereo MbSID in ZX Spectrum + 128K case (Wilba's sammichSID)
  6. I went ahead and modified my core so I can power the backlight on my 4x20 250mA LCD with 12V used Wilbas sammichSID "High-power backlight" circuit. -fed 12V regualted power straight from the psu to B+ on the LCD -changedd the T1 transistor BC337/25 to a BC337/40 -changed P1 trimpot from the 10K to a 50K works perfect the 5V reg. was getting too hot both regulating down from 12 to 5V and powering the 250mA backlight
  7. Ja 12V 1A linjært regulert Mascot psu topp norsk kvalitet :) en guru i Norge? jeg er ganske ny her
  8. Hey Wilba I was thinking I could modify my core from SmashTV to use your "High-power backlight" circuit. Would it work to: -feed 12V regualted power straight from the psu to B+ on the LCD -change the T1 transistor BC337 / 25 to a BC337 / 40 like in your sammichSID -change P1 trimpot from the 10K to a 50K Do I need another resistor in addition? It looks like R3 on the sammichSID pcb is part of the baclight circuit and that R4 is the same on both pcb's Your "High-power backlight" circuit works great on my sammichSID with 4x20 lcd even if I don't really understand why it's ok to feed 12V to a 5V LED :) I think this could be why the synth konks out now and then, because the 5V reg gets too hot
  9. the psu is top, so I don't think it's that the whole synth freezes, not just the LCD I was thinking it could be that I power the 260mA backlight over the 5V reg on the core module the PSU is a 12v 1A linear regulated 90$ industrial quality, should be fine for this job I only have a minimal with stereo SID
  10. My Mb SID synth has started to "freeze" now and then and shows strange screens like this does anybody know what could cause this?

    thanks sineSurfer, yes the elSID was definately an inspiration I went for a simpler CS though for my first build I might add a couple of buttons and led's for filter options for now I'm just thrilled with the sound :)

    thanks for the kudos Hawkeye and Antix yes arti492, I will burn in hell, but not for reusing a case for a speccy, I just bought the empty case I might burn in hell for buing SID's on ebay without knowing for shure that no Commodore was harmed in the process. Besides what's the bad thing about burning in hell anyway, that's really all there is to do there :) the buttons are also a reuse from the same case
  14. here's the rest of the pics of the synth pretty straight forward stereoSID with modules from SmashTV, 8580 R5's, minimal CS with 4x20 LCD, 8(7) banksticks, 5 analog pots, 500K stereo pot feedback mod, stereo volume pot, front panel from Schaeffer and rubber knobs from eagle (Mauser) all cased in a Sinclair ZX Spectrum + 48K computer case from 1984. I'm looking for a different knob for the menue encoder.

  17. thanks guys I thought maybe there was something in the settings I had missed out I had allready checked the wiring and the SID's next on the list was the solder joints, and there it was on the audio in el.cap. :) sounds amazing now glad I added a volume pot before the audio out, it can get pretty mean
  18. Hi, I'm finnishing my first MB project, a stereoSID with 8580 R5's, minimal CS, 5 analog pots and feedback mod I have a problem with the feedback only working in the left channel. I have RTFM, checked wiring, pot, connections, SID's and have enabled EXT audio in filter I am just starting to learn this synth, so I was wondering if there is something else I have missed in the settings for example If you have any suggestions, I would greatly appreciate it :) I'll also take the opportunity to thank you TK for this fantastic synth, and framework. It's not just a cool thing, but something that has improved the quality of my life, and hopefully will continue to. Thank's also to all forum members, none mentioned none forgotten, but you know who you are. Very inspiring to follow your work.

  20. Hi,

    SR's are Shift Registers, the chips on the DINx4 module

    J1 on the DINx4 has a 10 pin (2x5) connector

    I thought the two rows where the same, but the middle pin is not.

    So the 5 pin cable from CORE J9 needs to be connected to the 5 pins on the DINx4 closest to the edge of the PCB, NOT the row closest to the chips

    Good luck to you too

    Hal

  21. I know this look stupid, but I didn't find a way to delete the post
  22. Hi I'm building my first MB project, a stereoSID CORE and SID modules working, LCD working buildt DINx4 module from SmashTV and minimal CS DIN not working nothing happens when I press buttons or turn encoder what I've tried: -checked for shorts/bad solders on DIN and CORE, OK -tested cable between CORE and DIN, OK -tested button press by connecting VS and different pins on DIN with cable, still nothing happens -uploaded MIDIO 128, connected pins, still nothing -reinstalled MIOS and SID V2, no change any suggestions anyone? SOLVED I have a 5 pin cable going from J9 on CORE to J1 on DINx4 I thought it should connect to the 5 pins closest to the SR's obviously wrong, cause when I moved it everything worked :)

    Knobs

    sorry guys found it in the end on the forum of course Could anyone sell me some Re'an Black rubber knobs, P401?
