Announcing ILDAC-32 - an ESP-32 based DAC for ILDA projectors

[dchammonds]

OK, now back to our regularly scheduled programming.


So many things to like about the ILDAC-32:


Self-contained
USB 5V powered
Wireless control from phone with a simple interface
ILDA and 8ch wav file playback with stereo sound
SD card for mass storage
Something about uploading your own code to control the hardware using C++/Platform.io (I'm curious about that)
Lumia features
No need to know anything about the OS it uses


And a lot more stuff I've probably missed


And it's all in one gadget about the size of a pack of cigarettes. Oh, and I think the idea of including the PL FTP ILDA library
is a great bonus. I'd be happy to own one, if only I had a decent projector. I think you have a winner, Hank!

Not all ilda frames have dwell or span points.

James, I think you're the only one on the planet that produces minimized ild files like it was just another CAD file format.
Have you even looked at the vast ILDA content on PL FTP? You might want to consider an optimize to ILDA file option on your next
LB release.

What?

It has always been the case that ilda files can be saved fully optimized with whatever parameters you want. That's how it's possible to make files for SD card readers.

You know as well as anyone that there are no standards for optimization or any way to store any kind of information about them in the ilda format. It's just colors and vectors within frames.

You just need to clock stuff out at a reasonable scan rate and provide an adjustable runtime blank delay for the colors to a DAC. And if you want to go deluxe, add a variable repeat frames option to slow down animation.

I've been playing literally thousands of the ILDA files in the PL FTP repository, and I've never had a problem displaying them.

Obviously, many others have found a way to deal with this.

[james]

If you want to put together a collection of frame sets that all look consistent and as good as possible on any given projector, having the ability to optimize all of it with the same parameters is quite useful. It doesn't matter if it's ilda or wave.

Are you talking about the 'chil' (Chinese laser) effect in LB that busts everything down to TTL color?

What does this have to do with the ILDAC-32?

[james]

That's a specific short cut for SD card readers that are just TTL color. Anything else is possible as well.

The fact that I'm in the 19th year of working on this project and you've been there through the whole process and even developed your own project with compatible concepts and you don't know that is kinda mind blowing.

[james]

What does this have to do with the ILDAC-32?

It plays both ilda and wav files and anyone who gets one would find a whole lot of utility in LB for making files for it that look really good.

OK then, let's give Hank credit for his great work as he has credited many others for their input.

Thank you!

And if you want to go deluxe, add a variable repeat frames option to slow down animation.

That's exactly what ILDAC-32 does to slow down the ILDA animations. You can select how many times you want each frame to repeat. It's called "Frame Delay" on the web interface.

It plays both ilda and wav files and anyone who gets one would find a whole lot of utility in LB for making files for it that look really good.

If you only started with this assertion, I think the conversation would have gone a lot better! Thanks for your input and feedback.
