I have seen many circuits using a 555 Timer IC and an LM386 Amplifier IC = to makethe high pitch / ear piercing noise and cricket sounds. -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]On Behalf Of llile@SALTONUSA.COM Sent: Monday, June 14, 2004 7:31 AM To: PICLIST@MITVMA.MIT.EDU Subject: Re: [PIC:] Project suggestions... Other stuff that is useful, interesting, or devious, some of which I = have done: Gags: any noise that annoys a particular person can be simulated in a = PIC and put into a box, wrapped in pretty paper and closed by a bow. Possibilities are: Cicadas, crickets, rude bodily noises, annoying high pitched squeals, car horns, etc. Add ultra-bright flashing LEDs to your bicycle helmet. Look like a real nerd, and live to be 100 because you get more excercise and don't get squashed by a car.

The Robot lawnmower has been sitting around for a while half finished. = It actually will mow grass, and it can navigate as long as all of the barriers are on it's right side or in the front, the left side and rear bump sensors being in a state of disassembly. I have a pile of automatic stopwatches to build (this is actually for WORK) this is an adjustable current sensing stopwatch that times events = to milliseconds via a hacked interface to a Radio Shack sports stopwatch The super secret project is still on the back burner. I would tell you what it is, but then I'd have to kill you and eat the evidence. Only people who have been basting in marinade should ask about this project. The PIC Metronome (Koen, are you listening?) is actually moving forward. Koen van Leeuwen is collaborating with me on this project. -- Lawrence Lile Mike Hord Sent by: pic microcontroller discussion list 06/06/2004 10:38 PM Please respond to pic microcontroller discussion list To: PICLIST@MITVMA.MIT.EDU cc: Subject: [PIC:] Project suggestions... >This is always the hard part for me; coming up with fun and interesting >projects.

The one I'm thinking about making is a G-force datalogger...I have a friend who's getting back into RC aircraft after a hiatus for college, = and he's always wondered what kind of abuse his aircraft are subject to. I'm thinking an ADXL, a PIC, and a flash module. RS-232 to download, possibly with a hand-held LCD based doo-dad to display some abbreviated data. See? It's that easy. Getting around to doing it, now that's tough...
