Here are some Ideas! Motorcycle Alarm http://www.zen22142.zen.co.uk/Circuits/Alarm/motorcycle.htm Proximity Alarm http://www.geocities.com/IECMaster/circuits_alarm/cir_alarm005.html Touch Activated Alarm http://www.uoguelph.ca/~antoon/circ/alarm2.htm

More Info would be nice. What is the operating voltage? Is it a Bicycle Moped or Motorcycle? How much space do you have? Simple or complicated Design? Code alarm or Key alarm? Motion Sensor, Vibration Sensor, Touch Sensor? Tell me what you have in mind.

Well I found a datasheet for this chip but, it is arriving to me by snail mail. As soon as I get it I will scan it and post it here or email it to you.

Here you go.

Are you sure it is a diode? Where did you get the numbers from? If you got it from the circuitboard C10 means it is a Capacitor and 300 is it's value in Picofarads or Microfarads.

I f1.MN6617 (Technics) PANASONIC RXDT50 MN6617 PANASONIC RXDS650 MN6617 PANASONIC RXCD100 MN6617 2.MN6618A (Technics) PANASONIC RXCD100 MN6618 ound alternates for 1 and 2.

I see what you are going thru with this Chip it is a tuff one. I will not give up so easily on it. Here is what I have related to it. ISL3871 (WLAN MAC chip from Intersil) integrated Baseband Processor/Medium Access Controller (BBP/MAC), the ISL3871A is an upgrade to it. http://www.eazix.com/products/wlan/EZWFM01-01%20datasheet,%2011-05-03.pdf

A little more Info would help. I have the first one but the others need more info than that. Manufacture if possible. Transistor or IC? Give me something to go on. Here is the Datasheet for ST3232 B and C http://www.st.com/stonline/books/pdf/docs/7454.pdf Here is the Datasheet for ST3232 EB and EC http://www.st.com/stonline/books/pdf/docs/8784.pdf

Here is the other one! K4S641632F.pdf

Can't find E but did find D & F K4S641632D.pdf
