At first, I thought it was a bicycle seat.
MINIATURE ELECTRET MICROPHONE.
Where could i find such a component? How do i connect it? Doesn't it have any reference number like the integrated circuits used here?
Thanks
Hi
Micriphone you can find in old cassete radios with recording,in mobile phones,you can use anykind of electric microphone,look i your junk parts,if you have it :)
on your schematics there are two parts. How do you connect them ? Is the second part (with transistors) in case one wants to place more than 11 leds ?
That pesky link! Thanks macobt

very cool. but posting a video and a pic of the schematic isnt very informative, could you post some building details with steps and more information? this looks like a cool project to build
