HowTo: Blinking LEDs
ovelha.org — This is a tutorial how to create a circuit to make some bright leds blink corresponding to the music you are playing on your computer. Very explained and with many pictures.

- weesee, on 10/12/2007, -0/+0totaly e-mailed myself the link thanks!
good find DIGG - incognegro, on 10/12/2007, -0/+0it's dugg up
- mailman-zero, on 10/12/2007, -0/+0That was quick
- wiggie, on 10/12/2007, -0/+0can you feel it? the digg effect ?
- colebarnes, on 10/12/2007, -0/+0pretty cool...
now lets make two of the LEDs blink with the left audio and the other blink with the right channel...
shouldn't be too hard... - dylanA, on 10/12/2007, -0/+0very cool i might have to try that.
- conigs, on 10/12/2007, -1/+0I'm so glad this was "very explained."
I guess this program has alread started:

- n3xu5, on 10/12/2007, -0/+0Service unavailable:( I need this info can some one re up it?
- werkkrew, on 10/12/2007, -3/+0gay
- PStamatiou, on 10/12/2007, -0/+0nice work pasteler0. I've been following you for a while now, now you're digg worthy!
- vibe, on 10/12/2007, -0/+0Nice HowTo. Taking this further, i've lately been wanting to design a similar box which connects between an RJ-14 socket and a telephone. It'll blink when there's an incoming call. This will prove useful in my cube when i'm listening to my ipod and there's an incoming call. Anyone have any ideas where i should start?
- skwhirl, on 10/12/2007, -0/+0A LED wouldn't get my attention if I'm occupied with headphones on.
...Perhaps rigging a xenon flash tube to your phone line so that it is triggered by the ring pulses might work... - vibe, on 10/12/2007, -0/+0If i mounted a Luxeon LED on top of my monitor, I don't think I'd miss it.

- sound, on 10/12/2007, -0/+0POTS (Plain Old Telephone Service) phones ... the kind that connect directly to the phone company in the US ... use 120v ac at 20-30 Hz ... in the old days we would just put a Neon lamp across the line. If you have a 'digital phone' at your desk, the ring is signaled by a digital code to the phone ... much harder to easily detect.
See http://www.tkk.fi/Misc/Electronics/circuits/telephone_ringer.html for some good ideas on how to detect phone ringing. - Googled, on 10/12/2007, -0/+0Can anyone tell me where to find the materials? Ive googled P2 plug but nothing??
UK sites would be better :D - pasteler0, on 10/12/2007, -0/+0googled, You can find this on any electronics shop in your town. I can't help you find an on-line shop because I live in Brazil. :)
- pasteler0, on 10/12/2007, -0/+0strange, you can go to http://pasteler0.ovelha.org/2005/12/06/howto-blinking-leds/
and look this - Otto, on 10/12/2007, -0/+0Link dead. Coral has it though: http://www.ovelha.org.http.l2.l1.l0.nyucd.net:8090/pasteler0/2005/12/06/howto-blinking-leds/
- Otto, on 10/12/2007, -0/+1"Ive googled P2 plug but nothing??"
Read the article closer. He uses a weird terminology, but essentially he hooked that to the left audio on a stereo audio miniplug which was then presumably plugged into the speaker output line.
The gist of the circut is that the analog audio output modulates the behavior of the TIP31 transistor, which feeds power to the LED lights. This is a fairly simple way to do it, and has the advantage that all the parts cost less than $1 total.
