    Alarm

    I have a vibration sensing alarm circuit here. I want to build in a switch, which should act like a reset switch. It should stop the buzzer from sounding, the LED from emitting light and decharge the capacitor. I tried many time but couldnt find the right place to place the switch. The fist...

    Electricity

    hey, sorry about the late reply. YES, you are right, this disagram is actually really bad. But still, the answers are correct. I realised what mistake I did too. Thanks for your help!

    Electricity

    This question is giving me a headache, I just dont get the right answer. Please explain how I could solve this problem!! R = 36 OHMS Find the current in the 36 ohms resistor. Find the p.d. between a and b.

    Jubilee Clips

    I am going to attach a bike alarm to the bike using a jubilee clips. Is this a good idea? Are the adjustable around the frame? Does anyone have any other alternative suggestions? If the jubille clips are a good idea, are they available in plastic coated form?

    Waterproof??

    hey. good idea but it is neccessary for em to have the holes on the front side of the case (the side that the user faces the alarm usually) due to aesthetics. Is there any other way to stop water rain destroying the electronics without having the holes behind the case?

    Waterproof??

    :-\I have made a case for my bike alarm out of ABS. I have drilled holes to allow sound from the buzzer to come out. Now, the problem is, if it rains, my alarm will get damaged because the water would flow through the holes into the circuit. The ABS is waterproof already, but how can I prevent...

    Potential divider

    Hey. Thanx people for your help. Now I undertand eveything! ;D ;D ;D ;D ;D

    Potential divider

    This is a simple potential divider...The battery supply is 12V...The voltage accross the 200 ohm resistor is 8V...and the voltage across the 100 ohm resistor is 4V...shouldnt the resistor with the greater resistance have the lower Voltage...i dont undertand this?...please help

    Tlit switch

    basically a vibration switch is like a tilt switch, it has two pins and a mercury ball. The ball sits on top of one pin, when the switch is tilted (by a very small angle), the ball makes contact with both pins, completing the circuit. I asked my teacher and said that a vibration switch does act...

    Tlit switch

    And how does a Vibration switch work. Say it is a normally open vibration switch, does it return to its normal position simultaneously?

    Tlit switch

    oh ok....in your opinion, do u think that a vibration sensor would be more suitable for a bike alarm and this circuit than a tilt switch? If you dont mind, could you also explain how a vibration sensor works?
