this one only has bump sensors, yeah this responds to a whistle... thank you :)

check out V2 and V3 for more info...

Very cool!

I haven't done any coding yet for the microphones . i like what you've done .. My next step is to build the body . then i'll slap see what i can do for these microphones :)

Thanks :) KA567 (or NE567) PLL is pretty good at discriminating a certain range of frequencies, then all you need is a little amp for the electret mic. There wasn't much coding for it, 567 did most of it for me anyway. It pulls a pin on the PIC low when the frequency of the whistle is within the range it was set up for :)

wow, good job. I bet it took long time to program and build that thing

[technoshamanarchist]

Thanks dude ;) The programming part (about 200 lines of repetitive C code with loops and conditional statements) was the easiest, the hardware took the longest...

Thanks a bunch, ratings are also appreciated ;)
