camera deterent device complete
Well i been working on this for about 3 months now...
As we all know, going 60km/h in a straight four lane road seperated with an island, with no streets hanging off it, no intersections, and going for about 40km is rediculous....we tend to speed abit, and if theres a camera, FLASH, do that twice......no license.
So, to avoid buying a commercial bel, or similar system for $1400, i decided to design and build my own radar detector with some collegues, dropping the X band which is only used for basically automatic doors now, and concentrating on the two main bands used for speed detection being K and KA band. Using a phase locked loop for the local oscillator, accuracy in tuning could be acheived, and consequenty the warning range of about 3km is ample and hooked up to a buzzer and LED.
This of course is for WA and the multanovas and radar guns used here, not for mobile units like over east. If legislations passes to make these detectors illegal, the unit can be turned off using an illuminating switch on the dash, and since its not a commercial dash mountable unit, you cant be strip searched for the device, as it is behind the radiator in a consealed chassis.
I personally beleive this is a big acheivement and considering it cost us a total recourse of $250 for the prototype and $100 for each further model, we beleive we can target uni students and constant drivers while it is legal, and give some word of mouth and sell the units for less than a quarter of the cost of a commercial system, more warning time, and more suited to WA rather than internationally
Anyone here live in WA. The unit was tested and worked brilliant today on tonkin hwy perth, so more tests will be done soon.
