Subject: [alt-beam] D1 Chirppers
I read that you guys are thinking of making a
chirpping pummer? I've done it already. It's pretty
cool. It uses a D1 SE(but now I think I'll be using
Wilfs circuit) connected to a oscillator that chirps
it 2-3 second intervals. It sounds just like a
cricket. It's much more pleasing to the ear than a
constent buzz of a piezo buzzer. It's not very hard
to make you guys should try it.

would a 4001 diode work? Also you hook LEDs and stuff
on the circuit from the out put of the inverter to
ground right?

Just a thought... It seems to me (all this talk has made my mind dwell on
legs) that we use TWO types of sensors when we walk... one... a simple
switch (tactile sense of touch) and two... our feedback of presser ... So
wouldn't our bots also need two??? Well, need is not the right term... maybe
"better if"???
