  1. There are very few "kits" out there these days, because Nils & Wilba are no longer selling them. There's one guy that occasionally has them on eBay for ~$230 USD + ~$30 shipping. Then you need to account for the cost of SwinSIDs (the cheapest option) or another alternative, and factor in the build time (approx. 7-8 hours).
  2. I had a couple sammichSIDs posted in the flea market for a while. I sold one of them, and now I have the other listed here: https://www.ebay.com/itm/133688838489 Quick Note: I removed the 8580R5 SIDS that I was originally selling this with, because I'm using them in my MB6582 now. The instrument will sell with two SwinSIDs
  3. Congrats on building the momentum and seeing positive results... It’s an inspiring project for sure. Good luck with the remainder of your build. Looks like you have the original (Red Color) SmashTV Base PCBs? By the time I got around to doing my builds (last year) the only boards available were from Modular Addict (in signature Black). Cheers
  4. I still have a few extra ICs, including pre-programmed PICs. You can shoot me a DM if you like...
  5. Hi @rolfdegen. Thanks for sharing. Overall this project looks good and sounds cool! The Teensy v4 is clearly a capable MCU with it's fast ARM Cortex-M7. I'd be curious to hear about what motivated you to get started with this project and to build off of the Electrotechnique TSynth v4 foundation (http://electrotechnique.cc/)? You also chose to use a minimal control surface, so I'm guessing you're envisioning more of a sequenced, MIDI CC message type of interaction, rather than a live, interactive performance? Cheers
  6. Since you're looking for recommendations, I would suggest using Power supply Option E: http://www.midibox.org/dokuwiki/doku.php?id=wilba_mb_6582_psuopte IMHO, this is likely to be the simplest to setup, with the fewest parts. But best of all, it enables you to use a standard (and readily available) 12V DC "wall wart" power adapter, as long as it supports at least ~1.5 amps. In terms of the PCB mounted power connector, that option is really up to you, but to keep the retro spirit alive, many have chosen the 7-Pin circular DIN, which is what the original C64 used. https://ww
  7. @Noise-Generator Thought you might want to add the SIDKick, Teensy-based SID Clone to your master list. ...From Github: https://github.com/frntc/SIDKick SIDKick is a drop-in replacement for the SID sound chips used in C64s and C128s based on a Teensy 4.1. It is able to emulate two SIDs (6581 and/or 8580) and a Sound Expander (offering Yamaha OPL-based FM sound) at the same time. It makes no compromises with regard to quality: the emulation is based on reSID and fmOPL. It also comes with a few extras. Currently its features include: 6581 and/or 8580 emulation based on

    The case closes nicely with the JST-XH PCB connectors tucked nearly in place..

    I've also been working on a newer panel design, based on the original art uploaded by @listen202

    Early on it was tough to find the right C64-style power switches, but after a bit of research I found quite a few reliable sources.

    IMHO - Nothing beats the sound of real 8580 R5s

    Adafruit sells a nice RGB Character display, which conveniently places power for the RED backlighting on pin 16.. You can wire up pins 17 and 18 as well to mix in multiple color varieties... https://www.adafruit.com/product/499

    These longer 300mm JST-Xh cables turned out to be too cumbersome to work with. I eventually went with 100mm, which are perfect for the job...

    I decided to go with 22nf polyester film capacitors, because these are said to be the best match for 8580 SIDs (e.g., "Wilba's favorites", see the analysis in the forum post below)
  15. UPDATE: NKK Switches are also making a new part (M2022TXW41-FA) that's very close to the C64-style power switch. Although, the front-facing PCB mounting would need to be trimmed a bit to get a proper, flush mount on an MB-6582 or sammichSID. Both Mouser and Digikey currently have these in stock...So, it's good to have options. https://www.mouser.com/ProductDetail/633-M2022TXW41-FA https://www.digikey.com/en/products/detail/nkk-switches/M2022TXW41-FA/2105635 Cheers
  16. After some CRAZY international shipping delays (>4 months), my SwinSID Ultimates have finally shown up! My first observation was "Jeeze, they've jammed a lot of tech into these bad boys", from the top-to-bottom and on both sides... I count two MCUs (an Atmel Mega 168PA and an ATtiny85), plus a Xilinx CPLD (sort of like a small FPGA). Then there's three LEDs (Red, Green and Yellow - one for each SID voice), and that massive crystal oscillator (the SG615). Visually, they come across as being 'a bit over engineered', especially when you c
  17. I had a drive crash and lost the Kicad project, but I still have the slightly modified DXF file that I worked on, which was derived from Listen202's version. https://1drv.ms/u/s!AtmSvwylfFJagkpl5QlWo9tIUbJ0?e=mamgPG Working with DXF's in KiCAD requires several steps: 1) In the KICAD PCB tool, you'll import Listen202's DXF file into the Edge.cuts layer 2) make sure to size it properly, (approx. 232.3mm x 163.2mm) 3) Delete all of the graphics from this layer, but keep all of the holes and cutouts, since this will act as the drills layer 4) Import Listen202's DXF fi
  18. Looks like you're making progress. Seeing the boot-up message on your LCD obviously confirms that MIOS and the SID firmware are active. I ran those PICs in my own MB-6582 for more than 24 hours, with all the SID engines going and there were no hiccups. All the communications test with MIOS were solid (programming firmware to each PIC, multiple test runs of installing patches to the banksticks, etc.). Each core responded well to control surface tweaks and changes as well. It seems unlikely that you would be having issues with the PICs themselves now. Do you mean that you sol

    I'm using power supply Option-E, which is brilliantly simple and clean to implement..

    Figuring out how to get my PICs properly flashed was quite a learning experience. If not for the patience and fearless support in these forums, I would surely have many bruises on my head from banging it into the wall ;-)

    Really happy to see Modular Addict back online, with stock of these PCBs... https://modularaddict.com/midibox-6582cn-pcb

    Before buying all of the parts I needed for my MB-6582, I did some rudimentary parts and supplier research and I came up with a simplified BOM containing a couple different options.
