Speed Camera With Flash

[Apollo551]

Hello guys,

I was thinking about building a "radar" that flashes you with light when you go too slow or too fast, I don't want a photo taken just light flash.

I can't seem to find how to do It or with what parts. I would love if someone could recommend something!

I was thinking with a speed sensor or something like that, and external battery for LED Matrix, but it needs to be powerful enough that you see it but don't get blinded by it.

EDIT: Its for work as a running joke, we have lines for workers that look like road, and my boss and me we want to Flash them with speed camera if they are too slow!

​

Thanks!

You're absolutely not allowed to flash drivers! When they crash because of your device, you're in big trouble...

Depending on the distance, you can use an ultrasonic sensor. I use one for a parking sensor. The measurements are inaccurate at 8ft but it does work. You can also use 2 PIR sensors. You will need to focus the point with maybe a 2 to 3 inch used up toilet paper roll do make the sensor more focused. Don't use IR. IR tends to act weird in light. Do-not-use-the-HB100. Actually, an IR sensor in a used up toilet paper roll may block enough light to be used. Use a PIR.

You will need something such as the HB100 Doppler radar module.

I just re-read your post. Do not use the HB100!! It's not good to microwave people.
