Quoting the project site:

ILDAWaveX16 is an open-source, high-resolution, wireless laser DAC with SD-card playback, network control, and ILDA output.
Traditional laser DACs are often expensive, proprietary, or limited in flexibility, especially for those who want to experiment with laser systems, build custom projectors, or interface with low-cost driver kits.
The goal of this project is to create the "Arduino of laser DACs" - a flexible, hackable platform for makers and enthusiasts that can serve as a foundation for any DIY laser project, capable of real show control, yet simple enough for beginners and hobbyists to learn from.

I've watched this project on YT, from X/Y stepper motors 🙄 to this point.
Very impressive recent progress from ground level up, with lots of potential.
The PCB appears to be very similar to Hanklloydright's ESP32 ILDAC-WAV file player and atomic14's open source ESP32 ILD laser projector project, mentioned within his video.
TBC, I have no problem with any of this. Just wanted to give creds where due to the wizard behind the scene.

Thanks so much for sharing my project and for the kind words. I really appreciate it!

Just to clarify a bit of the background. It's no secret that I watched atomic14's videos, and I've openly mentioned that I used his ILDA parser function as a starting point. He's been a huge inspiration, and I'm grateful for everything he's put out there.

That said, the ILDAWaveX16 hardware isn't a copy of his design. While the op-amp output stage is naturally similar, the rest of the PCB is completely different - the MCU, 16-bit DAC, the single-supply USB-C power input with a step-up and bipolar conversion, SD-card interface, and so on, were developed specifically for this project. And just to be clear, I'm not saying that to brag - only to explain why I don't consider it a direct schematic copy unlike for example this (very cool) project: https://github.com/RealCorebb/bbLaser

Regarding HankLloydRight's ESP32 ILDA player you mentioned, I actually haven't seen that schematic before. If you have a link or source, I'd genuinely love to take a look for future reference.

Thanks again for the discussion and support!

Thank you for the clarification.

Hanklloydright's thread announcing the 2022 launch of his ILDAC-32 wave player. Hank is a highly respected active member of this community, who has generously contributed to the development of my own laser synth project's development, yet to be revealed.
FYI, this is Hank's product page.
Out of curiosity, what are your future plans for your ILDA player?
Best of luck.
