As far as a car is detected the system keep the speed displayed during 0.5s; meaning if two cars pass through the speed camera very close, the second one is ignored.
Also the system does work in both directions. The direction is decided just after the system boots-up by the first car that is detected.
If a car make an unexpected u-turn or moving backward, the speed will be 0 and the system will operate normally.
Just joking :-)
I was thinking about doing this for a couple of months now, but haven't gotten around to it yet.
Can you share in more detail what hardware you are using? Mainly the sensors you have. I have been looking around in online shops for something cheap to use, but haven't found anything usefull yet. I was planningon using a PIC for the brains. What are you using?
I love the led display, looks very very nice an alot better then the small LCD I wanted to use.
Nice work!
Extra question. Did you consider the fact that 2 cars could pass the first point before the first car passed the second point?
@imxlr8ed: My product is not distributed in any shop; It's something I develop and build in my own lab, to be honest I don't intend to do some profitable business with it. On the other hand, if a club is willing to own one copy I'd be keen to provide them. I just ask to pay for the components and striving to compensate the time I spend on building it which is 100% manual I'm afraid. So about the price I prefer to reply by private message.
The package include the electronic kit ready to be integrated on the RCP track; I provide a complete installation guide with picture and detailed instructions to explain how to place the sensors in the foam and also a user manual.
@LED: I see you're curious about the technology I used. Let me share some open details about what's inside. I used a PIC the sensors are made of simple but very good quality infrared LED and photo-transistor. I burst the output to increase the forward current. The lipo saver is made with separate electronic that is calibrated to guarantee a clean cut-off at 3v by cell.
@LED: "Did you consider the fact that 2 cars could pass the first point before the first car passed the second point?"
=> I'm not that sure to understand what you mean . Gona struggle to answer it anyway. If one car overtake another one when driving through the sensors, the speed camera will give craps, like any genuine speed camera . That said, to prevent the speed from being craps, there are internal intelligence to filter the sensors response and only display relevant speed.
So the top speed is 31 mph because anything above would be unrealistic, ain't it?
Do hope it answer your question well.
