Flexinoodle and I recently finished our collab: the fnpSID. It's a stereo mbSID v2 with added gm5 support for easy PC<->SID connection.

  • The pcb is basically comprised of a core module, a gm5 module and two sid modules and 5 banksticks.
  • It runs off a single 9V-12V AC/DC wallwart.
  • Since the gm5 gives us 5 IO ports, you can hook upto 4 other MIDI devices up to it.
  • It has the option of linking together multiple of the fnpSID PCBs to allow for either multiple stereo synths each as their own MIDI port, or linking the PCBs via CANbus.
  • Up to 2 of the PCBs can be fit into a single case, turning it into either a 2x stereo SID or a Quad SID setup ;)
  • To keep it as simple as possible the pcb does not have headers for anything else than needed - producing SID sweetness.
  • In the beginning we were a bit worried about the SNR with the usb and single supply PSU, and I went a bit overboard with bypass caps. But the result speaks for itself:
    Wilba: f*ck man that snr is sick
    nILS:  "puking baby"-sick or "phat maaaan!"-sick?
    Wilba: like pretty f*cking good
    Wilba: is like my mb6582 without the cs :)


Working on this little beast was a lot of fun and Flexi and I really like the results ;) We would like to thank TK for this incredibly nice project, Wilba for being a third pair of eyes with major pcb OCD and building one of the 3 prototypes and everyone else who made this little toy possible!

Okay, I'll shut up now, here's some pics:

Very nice! I really like the compact design and the enclosure.

How much did Gold Phoenix charge to do those 8 PCB's? How did you get the front and back panel's cut?

The panels were made by http://www.ponoko.com/. The PCBs were the regular "special" pricing deal from http://www.goldphoenixpcb.biz/

Do those capacitor footprints allow caps with 2.5mm or 5mm lead spacing? Brilliant idea! *cough*

Hehe, yes. And the filter cap positions match the filter caps on the mb6582 and the filter switcher pcb ;)

This looks like a nice little box that wont end up on ebay making blue lantern even more hated. If thats possible.
Are you going to share the snr that is not like puking baby?

Again Neato and thanks for the entertainment today!

I can't really tell what the SNR of the box is, cause it's below my systems natural SNR ;) Flexi, Wilba?

I don't have any fancy gear to measure it... nor any sound engineer learnin'... I just hooked it up raw to my Sony MDR-7506 and can hear the SID's internal "noise" and not any noise from the PCB itself, if that makes any sense.

Great work guys! :)

Would you borrow me your Solder slave for creating a duo coloured 16x16 BLM? ;)

Best Regards, Thorsten.

We don't lend, we rent him out at one TimTam per square inch of PCB.

Im not really sure how i missed this one guys,
but thats some really great work!  :D

Its probably the most hardsid-like midibox, that has ever been made to date.
(whats that I hear nILS? It makes you want to burn the hardware and delete the source?
hehehe, i mean it in a good way! ;))
