Hi there,
There moste bikers love speed i figure this would be interesting.
The drawing below is the scheme for a radar detector. I did not make this yet so i cant confirm if this will work. I will make one when im back from hollyday.
Anyway these are verry cheap components so there's nothing to waist.
All you need to do is calculate the length of the antenna as in the shown formula. you can use the calculator where i found this. Allso credit for this is on hes host. http://users.telenet.be/annette-guy/...ardetector.htm the 100k potentiometer is the squelch. turn it up till the alert triggers on distortion. then turn it back down till the alert falls off. then it is tuned. I guess you can replace the piezzo with a led just calculate the resistor. i didnt do electronics for years so i dont know it on my head anymore. The datasheet for the IC is found here. http://pdf1.alldatasheet.com/datashe...PS/MC1458.html if we look at it we see that the IC suply may be 18v so we can replace the 9v battery with our bike 12v if you dont know electronics just buid it as drawn, im pretty sure some components need to be recalculate if you change tension. otherwise frequencys will not work as intend. i will look at it after my hollyday.
Have fun with it, and remember...
in some country's this is illegal.
