LED Music Sync Lamp!

Step 4 Ready to Go

look at other instructables on how to make a lamp / print some stuff and roll it up or fold into lamp

put leds inside

play some music (max out sound card volume if it is possible to control speaker volume independently)

note: amplifier prevents your sound card from facting the wrath of your power supply. Connecting the LEDs directly to the amplifier output has so far given dim LEDs and slow frequency response (thats why the transistor and the voltage regulator)

Note, 150 ohms is enough to get the leds working at reccomended voltage
however, they are not all of the time so they dont overheat if theres a lil overvolting
be careful, remember to set amp to zero first then turn up volume

where do you conect groun of leds.

Can I ad a mic instead of driving this circuit from a sound card?

[optimized4perfection]

yea,i have seen some on the internet where they put a mic instead, but i dont think it works as well

[sp33dstix]

any links for that?

[unmanagedtn]

I am working on a take off of your circuit that is standalone... Thats why I asked...

[optimized4perfection]

ok. tell me if its good, might wanna try

[unmanagedtn]

will do ... :P

[monstormaniac]

have you done this yet?
