okie let me explain my situation.
i am doing motion detector alarm for my FYP.
so this motion detector will be connected to car alarm , which means tat
the motion detector will oni be activated when the car alarm remote is enabled.
and motion detector deactivated when car alarm is disabled.

so now , i hv to tap current from the car alarm (to get a signal) to turn on off motion detector.
when the motion detector receive this signal(pulse), den oni motion detector will ON.
when the motion detector again receive the signal(pulse), it will OFF.

simply it means tat motion detector will work oni when the alarm is enabled.

so now, is there any relay or switches that can perform that kind of job ?

when receive pulse, it will turn on circuit,
when gain receive pulse, it will turn off circuit.

the current that i hv researched is PULSE. not continous current.
it can be tapped from the central lock/unlock wire.

thanks.

I give a few ideas.

1. Prolong your laptop battery operation
2. Create handphone that use during flight
3. All-In-One computer motherboard
4. Power saving devices

Finger-print scanning like the old Mission: Impossible episodes
Purpose: To only identify approved members who are allowed to access the content of the secret material



Watch the scene at 3:00

A teleporter
u will be the richest man in teh world if u manage to do this
This . . Is your final project

Do et

don choose those "very" high tech stuff or it'll ruin you. choose simple one lar like infrared camera ......

----

all you need is infrared converter plus cmos sensor/ccd ...... and test subject is probably your FYP partner (best if girl)

trust, sure can get an A one....

magic carpet

electrical based car taht saves oil and consume less electricity

May I know where you are studying, TS?

think is MMU
if really mmu, then TS u re very late alrdy

RF door is so yesterday. do a line robot lah. parts are everywhere. www.cytron.com.my

robotics for the win

Some ideas -

http://www.electronics-project-design.com/...Processing.html

build a laser guided missle under the cost of RM1000 bucks !

1)scrap laser from dvd writer -rm20
2)clock battery -rm5
3)few salotapes and wire cuttings -rm4
4)????
5)PROFIT.

guide it with your own hand of course.

which uni are u from? im doing my final year project as well..

so for your case, i would suggest RFID scanning. get an PIC chip, RFID card and do ur programming. there are also ready made (just some asembly needed)

pm me if ur really interested.

errr.. find a way so streamyx cannot trottle us ^^

how about this? i'm sure some will be interested. but whether get approval or not, we don't know. haha
