Could there be one (or more) pins of the OPTi chip not properly soldered? I know it happened to me in the past, although I generally solder them under a heavy magnifying glass, and sometimes under the electronic microscope, and that drove me crazy. I cannot tell from the picture, but I'd re-check …

Just printing it.... Ever thought about splitting this into two parts so the front panel could be printed face down for a smoother surface and later screwed or glued to the main part? I've tried a couple of things -- PrusaSlicer has a function where you can add studs to a cut surface for a press- …

Probably an oversight on my side, but I can't find any information what OLED display you designed this for. Oh, oops. The OLED is a standard 0.96" 128x64 I2C module using an SSD1306; the same kind that you can find on Amazon. Here's a link to one possibility: https://www.amazon.com/Hosyond-Display- …

I discovered that the hot swap issue is also related to the amount of images on the SD card. I use 64GB cards now and split my images across 3 of them (for now) - 100-120 images each - and now everything works smoothly. I think with too many images the device simply gets overloaded to the point …

Have a question for you: Which exact rotary encoder are you using? I received my built boards and they work fine except the rotary encoder direction is backwards (i know some have the CLK/DAT pins reversed) and takes 4 detent clicks before the encoder registers a movement. I.e selecting different …

The Qwiic connectors aren't populated on there by default because you could add a right-angle one or a straight-down one, but if desired, I could do a little searching and make a revised BOM/CPL file pairing that has one of the connectors populated. Yes please , that would be quite nice. Here are …

The soldering appears to be of very good quality, thus you're right, it's not from there. But I have noticed that you have JP3 closed. It should be open (i.e.: no jumper set) so that the software could take control of the card. Otherwise, the card would attempt to read the EEPROM, which is empty. …

For some reason, on your screen capture, the codec is detected as AD1848/CS4248. Is that what you have used? I would really recommend CS4231A as the card was constructed with that one in mind. Or if you already use AD1845 / CS4231, then this has to be selected in the AIF setup, first. So, that's …

I assume there is a minimum order quantity if you order it at one of those manufacturers. Just in case anyone in Europe is willing to organize a group buy, I’m in! Same here - getting this done on your own would be a big pain in the butt. Postage for all the parts alone would quickly ramp up. It …

I wonder: if you have the audio shield you could technically solder the Pico W underneath the board instead of on top - I think it could fit and the USB port would probably clear the caps. Then again, with a front panel, is there any reason to even have a Pico? No - that would require a complete …

You should look at how the Bulky MT32 internal device is built. 2024-03-22 02.00.42.jpg You could mount a PCB 5.25 or 3.5 faceplate to the controller PCB. Then just have a 3d printed tray and rails. Silkscreened PCB faceplates look really smart and are super cheap to have produced. That's a good …

Assembly Details The M2 x 4 self-tapping screws are to secure the OLED display down to the bezel. Don't overtighten!

Looking more-or-less ready to go. These pictures are just a test mount to make sure the footprints for everything is good, nothing is actually wired up for real here. I've added some chamfering to the inside of it so that the board will slide into the tray a little easier, and so it's easier to …
