single chip 'colour organ'

[swanny]

For those of us who are young enough to remember the old 'colour organ'
of the 1970's, here it is again. This time it's an LED one, pretty much
all on a single chip. Now where's the fun in that?

With today's "music", only one of the three PWM drivers will be
operational.

Ho Ho, the doof-doof pwm driver!
Frank, anyone who remembers the colour organ probably doesn't listen to
today's "music".

Wow, the old MusiColour is now High Tech, and all in one chip....
Ahhh..
Modern technology its just wonderful..
I wonder if they will bring out a kit that will also do a chaser mode as
well..
Ill have to order a 1000 and start designing..

There are T1 3/4 RGB LES (5mm round) with built in PWM chips that
constantly cycle through a small set of colours. There is no control
over the pwm though.

I can just see the 'ringtone lightshow' on the next wave of mobbly dogs.

My neighbour's teenagers removed the tweeters and midranges from his
speakers to enhance their listening pleasure. <shrug>
