That's my thought as well! My gut was telling me that I needed to flash something on it but I'm a noob at this stuff still, so I thought there was a chance I missed something and maybe the BIOS flash also covered the ATTINY. I found a firmware he posted for someone to test a while back for the …

I love this setup. You truly have created something special here my guy. It fits with what I feel the whole principle of this build should be. Would you mind sharing the name of the case you used? If not that's cool Do you think the AGP riser would work without shortening it? I just don't have the …

Hey guys I need your help. I built my ITX llama and everything seems to be working except anything connected to the ATTINY. I checked all my solder connections and everything seems to be fine. the LED is soldered in correctly and I can trigger it with my meter when I'm testing voltage on the pins. …

By the way, since you are using the CM4, I have some previous projects with it which build a CM4 "sandwich". Here is a link to the github with all the projects. https://github.com/opencomputeproject/Time-Ap … bation/Hardware

Please don't drop the ESP8266. I love the retro modem so much.

Even though I had a functional ITX board, I decided to make one from scratch and solder the components one by one. I always enjoyed building Eivind's art work piece by piece, manually. One more thing, I routed the ESP8266 to the outside of the case and I was facing problems when I was trying to …

And I got the SM-750 with HDMI output to work. Yay! Now I want to inject the audio over the HDMI cable as well. Not sure if that is analog and digital. If digital, I need to figure out to do the conversion first. Hey, I know this is a bit of an older post but where did you get the SM-750? Any time …

OK edit number two I was able to get everything working by adding that capacitor and checking the circuit on the USB I found I wasn’t getting 5 V due to one of the fuses, not being soldered all the way, which would explain why I needed to provide power to get the chip to flash also had the same …

Here are the results from modifying the front panel to host the OLED display for the MT32-Pi Nice , going to do something similar, but also add buttons to be able to switch btw gm and Roland mt32 :) Yeah, I thought about doing that in a clean way. Then I came up with a touch based method were you …

Hey guys, just finished building my TinyLlama v2 board but I’m having problems with the CH559. I tried following the instructions on the GitHub; unplug the HID_POWER jumper, disconnect power from the board, hold PRG until the device shows up in the WCH software but that never worked. I tried …

Also, in case anyone likes a proof that this is working, I attached more pictures. I also attached a picture of how much of that cable I had to trim. That's an interesting idea to have it come out the I/o shield, I like it. I've never used a Pico power supply before. Do I need to use an AC adapter …

Alright, so I was able to pack everything (ITX llama, Voodoo 3000 and a SATA) in the mini ITX case (bought off ebay and attached the picture). To do that, I had to use an AGP riser from MODDIY. But man, that was then the nightmare began. With the riser I was unable to get the card working. Then I …

Don't worry, you might be able to fix it if you got a soldering iron. Try checking the continuity of that trace first.

@Eivind, would you consider adding the changes for the wavetable? In ITX case things are much easier. We just need the DC2DC to provide the +/-12v and a jumper to switch between 3v3 and 5v Midi-in.

Sweet. Got it working! Thank you Eivind First I tried with removing R30 and R29 and things worked. But then I put the resistors back and added two NPN-Res (Q2 and R28, R29 from TL2 BOM) inverters back to back and things now work for both the Pi and DB50XR. Conclusion, DB50XR requires the -/+12 ( …

I got the +-12v working, but still no sound. Anyone got some experience with DB50XG and what is takes? Should I buffer up the midi signal from 3v3 to 5 ("TTL")? I doubt that makes any difference, however I need seeing other people put an optocoupler like 6N137 on that line. Any suggestions?
