Is another book from Bert van Dam about JAL language and what projects you can make.

[quote]This book contains 50 fun and exciting projects for PIC microcontrollers such as a laser alarm, USB teasing mouse, eggtimer, youth repellent, soundswitch, capacitive liquid level gauge, "finger in the water" sensor, guarding a room using a camera, mains light dimmer (110-240 volts), talking microcontroller and much more. Several different techniques are discussed such as relay, alternating current control including mains, I2C, SPI, RS232, USB, pulse width modulation, rotary encoder, interrupts, infrared, analog-digital conversion (and the other way around), 7-segment display and even CAN bus[/quote]

...

[quote]All software that is used in this book can be downloaded for free. That also applies to the open source programming language JAL. This powerful and yet easy to learn language is used by hobbyists as well as professionals.[/quote]

"Youth Repellent", plays Barry Manilow and other such artists to dislodge and move on stubborn Youths. Used to great effect by many councils in clearing those pesty Youths from public malls and shopping centres. Order your supply today! :)

I heard tell of testing of acoustic "youth repellent" devices that generate an annoying/unpleasant high frequency noise that it is alleged young folk can hear, but those of us who have been less kind to our ears, cannot.

I've got concerns about what it'd do to babies and young kids of only a few years old, if it were to be widely deployed in public places.

Youth repellent is most likely a very high pitched noise that to the young sounds like angry mosquitoes on steroids and that us oldies cannot hear. Or it could be the mosquito device to deter young people (this sux and we can all hear it).

Seem like a lot of trouble to go to, when a simple sign saying "Hard work and no computer" would work just as well.
