Anti-Theft Security for Car Audios -  (circuit / schematic design added 6/06)
Audio Refinement Complete integrated Amplifier -  The Complete' is made to design by Yves-Bernard Andre (YBA). My unit s/n is an early 00026, probably later copies are different from the first batch. I used the amp for two years, and the only reason to dig inside it, apart from 'how they did it' curiosity, was to disconnect the volume pot motor. It returns to zero at each power down....(added 04/05/06
Audison LR604XR Amplifier (Car Audio) -  Of the few car amplifiers I tested, gutted, decyphered and fixed, this one seems to be the best in design quality. Too many car amps (although solidly built) are apparently designed by computer class students, too many traces, too many vias, absolutely wrong component placement etc. And on schematic level....(added 04/05/06)
Auto batteries charger (Pd) -  ....
Auto Burglar Alarm (Randy Linscott) -  This alarm circuit is based on two 555 timers. The alarm will sound your car horn if anyone opens the car door while the circuit is armed. The timers will allow you to leave the car without sounding the horn. To turn the circuit on S1 must be closed..
Automatic Dual Output Display -  This circuit lights up ten bulbs sequentially, first in one direction and n in  opposite direction, thus presenting a nice visual effect. In this circuit, gates N1 and N2 form an oscillator. The output of this oscillator is used as a clock for BCD up/down counter CD4510 (IC2). Depending on  logic state at its pin 10,  counter counts up or down. During count up operation, pin 7 of IC2 outputs an active low pulse on reaching  ninth count. Similarly, during count-down operation, you again(added 10/04)
