Sound activated leds in a slim

[Rodent]

 Thanks to Gizmo613 he sent me a few of these , they are a remake of the PulseVU 2x
I just installed on in a slim and went pretty fast   Green leds 



video proof its kind of long  but wanted to get the full affect

This is badass if they have this for PS4 I'd totally buy that board

The pulse VU was originally created for the PSP. It can be adapted for the ps4...... if you can find any left.

I have a few stashed away found them on ebay $35 each . and couple that Gizmo613 sent me that i bought off him

[Gizmo613]

my auction still list them there i believe.

I have been trying to get a PS4 to see if this can be done, we talked about doing this on Xbox one, I think Ghost said it couldn't be done on Xb1 due to no AV cables and something to do with the  Digital audio signal on HDMI

You only have a digital audio signal on hdmi, you probably need to convert it to an analogue signal prior to using it for sound reactive mods.
I think you can get hdmi audio extraction boards fairly cheaply on ebay.

I haven't seen them in a while on ebay usually when you do see them there expensive

Yeah I remember that, looks like the PS4 is the same, no support on the console for outputting analogue audio direct.

Off the top of my head your options are:
Buy /build(no experience here) some circuit which can decode digital audio from S/PDIF or HDMI.
Feed an external analog line back into the console, this could be from your receiver or TV (most of these have a analogue line out for headphones and stuff that strips from HDMI).
Put a small microphone inside your console, if you are using speakers you may be able to get it to pick out certain lower frequencies or something and not react to ambient noise.

An unfortunate consequence of the increasing quality of home media equipment, is that the conversion to analog audio is has typically moved a lot closer to the speakers that need to be driven, which is great for noise rejection ect, consumer stuff, ect. but sucks for us modders.

In case it wasn't entirely clear, I attached a picture showing the difference between analogue and digital signals.


Edit: Haha the amount of times I change between using American-English and English-English, so filthy.

 As Ghost has stated i just added to his comment here. with information how i did mine


I just had my xbox one sent back for repair , and I do not have much experience with all the out puts in the back of the console  is there a Stereo output?
if there is i am not sure its possible or not but you could do like they do for PC

This is how i built my Flamed xbox 360 instead of stereo jack i just hard wired it to the audio out puts and bridged the hdmi points for it work with hdmi
yet the xbox one is more updated


work log for xbox 360 which is same method i used for this slim console just used a pulse-vu chip

I'm not balsy enough to try it out first but if someone made a good tutorial I would definitely do it

I would try it i had a PS4

I did a brief look around, Cirrus Logic makes a nice little chip (albeit a little overkill for the application) that could probably get this going on the xbone/ps4, see CS8416. It converts the S/PDIF signal to a serial based audio stream, which would be easily processed by a nice microcontroller, hell you could probably fft it on the fly. Alternatively you could pair that chip with I2S decoder, something like the UDA1345TS and get that to provide you with a raw analogue output and pass that through a chain of filters/amplifiers -> some current gain -> drive some leds.

I am actually kind of keen to work on this as a little project (I don't have an current console but it would translate pretty flawlessly between most systems). Would anyone have any interest in sound reactive board purpose built for driving LEDs from a digital audio signal (maybe configurable frequency ranges ect)?

this is the chip your talking about?

That's the one, I have found a few other but this was the cheapest even with that eight channel multiplexer on the input.

Edit:
Scratch that, the nxp UDA1355H is more interesting, as that has a built in analog audio output as well as the i2s stream. http://www.nxp.com/documents/data_sheet/UDA1355H.pdf
Only comes in QFN packages though.

I'm very interested to see this play out! If or when this gets figured out for ps4 I'd be more than happy to contract out my ps4 for this led install. I've seen some U.K company that does basic led mods on ps4 but a pulse chip would be sickness!
