This thread has kinda died down. I think i have all the parts and pieces i need, i just need some instruction to get it all together. Would love to get this going again.

But I really wanted 800KHz, and more accurate timing, so I rewrote it in assembly, it's got pretty much perfect timing now and it only takes half the time to update the LEDs.

I have been playing with WS2811 LEDs a lot lately and was thinking about DIY an ambilight system for my home plasma. So far I've used this OctoWS2811 library that uses DMA (no cpu) to build the waveform. Works great! Might be interesting.

The signal is converted from digital to analog and then back to digital as part of the capture/averaging process, it's much faster doing the averaging that way, using just a small MCU (clocked at 80MHz) for the processing work and LED control.

I was think about using one of theses chips from Analog Devices like the AD9880 or ADV7842 to output RGB values readable by the Teensy3, do you think this could work?

There is also this new STDP4320 that looks interesting.

I'll post more details on the inner workings once I get LEDs and a bit further with the project.

Looks like you never posted any details, I hope you won't let all this work go to waste, either by selling your product of sharing it with the community.


Wish you the best with your projects!

jvjessen: ...your project is dead??
post #155 of 234
I followed this thread as not member since 1/15/13.
As jvjessen hasnt answered for more than 4 month i sadly believe his project is dead.

I want to appeal to jvjessen and all the guys who have the skills for a solution like that to get some motivation of pushing this project. (or start a similar one)
I'm not sure if I can understand the fear of sharing this.

Its clear that you cant share officially the completed device because there are some people who wont "love" it smile.gif
But to be honest - there must be a way of giving good hints or something like DIY tutorials - if there is a will.

I hope this project doesnt die and someone can put it alive!

cheers!

PS.: I couldnt find anything about it, but for my interest: is your solution supporting 3D?

Sorry guys, while the project is not totally dead, I have not touched it for some time. Been busy with other projects, mostly the controller project.

I can't really say for sure when or whether I will do more with this project, I did do some work on a slightly simplified version that I intended to share, but I didn't get very far on it.

Maybe once I get the controller project into a more complete state.

Cheers

Hey jvjessen,

I'm very glad you answered (and give us some hope).
As you can see - there are some people very interessted in this project as well.
Looking forward to see your controller project done and the simplified version of this AmbiLight.
Maybe you've got enough ressources to do it simultaneously :-D
Hope to see something here in the future...

Thanks a lot and cheers!

Started connected my arduino to my network so that i can control lighting effects via the web/my phone. However i would really like to get this ambilight pass-through going to have as an on/off state. Anyone make any head way on getting the hdmi pass-through variety working?

Are the ambilight Lightboxes on ebay worth a damn?
post #160 of 234
he Arduino is connected to the RPi via USB. I bought an all-in-one package called "ArduLights", which contains a pre-configured Arduino (or clone) and a WS2801 50 LED stripe. I created my device config with the Boblight Tool, http://www.sedu-board.de/sedu-ambilight/howto-boblightconfigtool/
