OK, had to share this one directly. I love it when the visuals exceed my expectations.
That looks amazing!
That’s fantastic!
(Had to watch it on a PC, the video won’t play on my phone for some reason.)
Incredible effect!
Holy shades of animated Mandelbrot set.
Extra fancy! Super effect.
Super effect. Are you using FFT on the board or a separate chip to do the analysis. ?
@Yves_BAZIN I am running a 2nd teensy with the teensy audio board for the audio analysis / fft and then transferring the results via serial. I could not get the teensy audio card to play with the Octo board and fastled on one teensy .
Does this project have a name & any more info? Would it be ok to share this link & video outside google plus?
@Mark_Estes Hardware: audio board is lower right. there is a teensy 3.2 hiding underneath. Teensy 3.6 on the OCto board on the left. Connections between them are serial1 ( TX1, RX1), Vin, Ground, and one pin to coordinate the data flow. I power one of the teensys from usb and the other one gets juice from the hardwired connection. This was first version. Made a better set with hard connections yesterday.

@Mark_Estes Hardwired version, first test, it works. still need to snip some long pins. Not as quick since this one has a teensy 3.2 vs the 3.6.

@PaulStoffregen I never gave it a name. i guess here I have called it the “64 x 64 LED matrix table” (it was the 43 x 43 before that , and the 29 x 29 before that, and the 23 x 23 before that, and before that, i was born and did other things. The matrix normally lives inside the ikea table is is now sitting upon. If you filter down to on all the posts here, you can find my earlier posts. These should provide a history of this project and other info I shared, including the code at various stages. Yes, you can share a link. Feel free to ask questions too.
Nice! Reminds me some some of the old WinAmp visualizations.
@Mark_Estes great stuff. You are using the Ethernet wires to distribute the data signal right ?
This… is one of the best visualizations I’ve ever seen here… wow…
@Yves_BAZIN yep, the Octows2811 board has two ethernet type jacks (rj45??) so one can take one Ethernet cable, cut it in half, and end up with connections for the 8 // outputs. I like how clean this makes the wiring. https://www.pjrc.com/store/octo28_adaptor.html
@Mark_Estes thx you I was thinking of doing that but did not think of the twist ground/data. As you can see i need to ‘plug’ via pin and screws which is not ideal. missing/deleted image from Google+
That’s Awesome! are you using an MSGEQ7 at all? would love to check out the code
@Mark_Estes What audio info are you shifting from 3.2-3.6. Have you got a video with audio. Looks great.
@Tommy_Sciano No MSGEQ7, though long ago I built a few widgets with that chip. I am using a seperate teensy 3.2 and the audio card that the teensy folks sell to process the audio. The teensy is constantly sampling and running the fft and processing it into an array of 17 bytes. Each element in the array covers roughly 1/17th of the audio band as we preceive it. The fft spits out 512 amllitude values. i groyp them together in bins to represent the results. As frequency doubles with each active, the number of elements in each bin increases as frequency increases). The array is scaled to give a range of 0 to 64 to represent the intensity. I use Easy Transfer (some great code) to pack-up the data and send it over serial to the other teensy.
On the other teensy (the one the is running the leds), I also use easy transfer to unpack that data back into an array of 17 bytes and then a bit of code to convert the array of 17 into an array of 64. This array drives most of the audio based patterns although I also use the original 17 in some patterns.
@Gibbedy_G (see the above). The video at the top of this thread is an audio driven pattern. here is another with the input gain set a bit too high.
