    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)
  9. UPDATE: NKK Switches are making a "perfect" replacement for the C64-style power switch (M2022TXW41-FA). It's available in stock from Mouser and Digikey... https://www.mouser.com/ProductDetail/633-M2022TXW41-FA https://www.digikey.com/en/products/detail/nkk-switches/M2022TXW41-FA/2105635 Cheers
  10. Been waiting for more than 4 months for these SwinSID Ultimates (e.g., the Unicorn of SID clones) to show up from Poly.play... You'll notice there's quite a bit of tech jammed into these bad boys, from the top-to-the-bottom, and on both sides... I count two MCUs (an Atmel Mega 168PA and an ATtiny85), plus a Xilinx CPLD (like a small FPGA). Then there's that massive crystal oscillator (the SG615)... They may be 'a touch over engineered', but perhaps we should just let the actual sound be the judge... I decided it would be easiest (and
  11. 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

  13. Did you ever get this all the way to FPD? I'm all thumbs with CAD tinkering, so if you did, and could share it, you'd be my hero. :) Thanks.

  15. Hello Friends.. Our progress cannot be stopped. This time we really accelerate. The Fx PCB is ready. Now we has started to route the "Jeannie" mainboard. I'm curious.. Fx board Mainboard This is the first draft of the "Jeannie" mainboard. There will still be some changes such as the Teensy processor module (left). This is moved further down so that the USB socket can be used from the outside. Greetings Rolf
  16. Here is some talk about open vs closed: https://forum.arduino.cc/index.php?topic=695264.0 In the second post someone says: "One disadvantage of a N/C is that with a pullup, as most switches spend the majority of their time in the un-pressed state, you will have increase current consumption." If this is correct i'd get a normally open pedal.
  17. Ok, i found an answer here http://midibox.org/forums/topic/20751-fatar-tp40l-midification/?do=findComment&comment=181241 If this is the best way, i'd like to know what kind of pedal is the best. Normally closed or normally open?
  18. I'm no expert. I guess you should see debug output in the MIOS Studio terminal. Search for "debug" in http://www.ucapps.de/midibox_ng_manual_fs.html
  19. Hi, i want to add a sustain panel to my NG based keyboard controller. Which switch type is the best? Normally closed or normally open? (i somehow think normally open would be better, because the circuit is only closed on press = less energy consumption) What would be the best way to connect them? Via analog or digital input? Thank you
  20. for example meterbridge 16 x 16Segment Meter - needs 4x 595 and driver Transistors ---if they where on the same PCB...but this is maybe not the case, so you have 8x 16Segment PCBs where you need 3x595 and this 4 times to get to your 32 channels - this is 12 595 which is i think not a big deal...
  21. Wow, that's really a great idea ! Never thought of having the text like this. By the way, if you use this method, I have a question : what software do you use to produce the text to be printed in 3D ? I am using Freecad, but I never found a good way to generate 3D printing of text from it Benoit
  22. 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
  23. Now I put my own pic back in and its not even sending an upload request when I power on, any ideas why that failed?
  24. I have also tried your preprogrammed chip, I'd 0000 0000 0000 0000 and I get some writing on the screen “MidiboxSID V2. 044“ and MIOS8 V1. 9h" but when I query the core I get bootloader is up and running not application is up and running any idea why? Thanks
  25. Hi I have managed to program my own pic on mplab ide and get a response from the core after going through some of the midi trouble shooting pages, I did a loop back test to find out how to set my midis port 2x2 correctly then soldered a wire between the rx and tx pins on the pic socket and put the pic in and powered up on the core and the core signal started feeding back f0 00 00 7e 40 00 01 f7 then I soldered an led between the tx and ground pins on midi out j12 and it lit up, but when I try and upload the midi hex file for the pic it says no response from core please reboot the core (e. g. t
  26. Thank you for your reply! I’m sorry I meant switch. A snap action switch is a switch which stays pressed until pressed again. I only searched for the German term „rastend“ but couldn’t find the right one. I’m still not sure, if it would be easier so find very small switches and add my own button caps. The SSL EQ strip consists of four buttons and a LED next to everyone. I don’t want to add more DOUT modules for the LEDS, I simply want to chain them after the switch so they will be on when the button is pushed. Therefore I need snap action switches These will be the only switches, whi
