The Tiny Beatereater 2 - Raw Demo

YouTube Uploaded by elohess2 on Mar 17, 2012

"News from the Beateater. Today I've tried to make some optimizsation of my first publish schematics. I added a "signal flatener" to the output of the amp and I added a passive lowpassfilter before the circuit. Now the beateater has a much better response to bass signals like bassdrum and other bassy instruments.

In this demo we see the raw mode. The ATTINY after the amplifier listen only to the flaten output signal and when a high water mark is reached the LED signal rises. In the next step, the alogrithm must be optimized. But this part every DIYer can implement his own ideas. I'll do a "don't response to base for defined time to supress ghost notes" next.

Working with the ATTINY (here a 85) is fine. It's cheap and the programming with an Arduino IDE is possible."

"I finshed the project "Tiny Beateater 2" today. The video shows in the beginning some sound sample in which the Beateater triggers my famous "Raidio Lala". And then I start a walk through to the features to show how it works. Also the limits are described. The schematics and the software I'll publish during the next week. So come back and look here for a link. When it is published, I'll post the link here."
