Anti Theft Motorcycle Alarm - Any number of normally open switches may be used. Fit the mercury switches so that they close when the steering is moved or when the bike is lifted off its side-stand or pushed forward off its centre-stand. Use micro-switches to protect removable panels and the lids of panniers etc. While at least one switch remains closed, the siren will sound. About two minutes after the switches have been opened again, the alarm will reset. __ Designed by Ron J
Anti-Hijack Alarm No.3 - Automobile Alarm Circuits: Like the first two Hijack Alarms - if a door is opened while the ignition is switched on - the circuit will trip. And after a few minutes delay - when the thief is at a safe distance - the Siren will sound. But this time the engine does not go on to fail automatically. instead - it will continue to run until the thief turns off the ignition. Then the engine will not re-start. __ Designed by Ron J
Anti-theft Car Alarm - Here is a simple AntI theft car alarm device for your Car. it generates a loud alarm when there is an attempt of theft. When the intruder opens the door, the circuit senses the attempt of theft and after 2 minutes, the alarm will be activated. The time delay is provided to help the user to leave the car after arming with the __ Designed by D Mohankumar
Anti-Theft Security for Car Audio - This small circuit, based on popular CMOS
NAND chip CD4093, can be effectively used for protecting your expensive car audio system against theft. When 12V DC from the car battery is applied to the gadget (as indicated by
LED1) through switch S1, the circuit goes into standby mode. LED inside optocoupler IC 1 is lit as its cathode terminal is grounded via the car audio (amplifier) body. As a result, the output at pin 3 of gate N1 goes low and disables the rest of the circuit. __ Learning Electronics
ArroW Lighting-TI DC/DC LED Driver Solution - in this article, 2 lighting applications of TI TPS40211 will be presented. TI TPS40211 is a DC/DC LED driver controller which accepts DC voltage up to 52V and is able to fit various kinds of LED lighting application including MR16
as well as streetlamp application. __ Designed by James Ho, Arrow Asia Pac
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 __ Contact klausmobile @ yahoo.Com
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 __ Contact klausmobile @ yahoo.Com
