Cheap radar

[BrianG]

From the various threads I've read at other forums, it's meant for very close-up measurements - like measuring speeds of 1/24th scale cars on a hot wheels track. Must mean the beam is not very wide or extend very far.

Soooo, I wonder if a little modding is in order. :017:

Since trying to get a reading on a passing vehicle is not easily possible, what about removing the guts and putting it on the truck? Have it pointing down or at an angle so it sees the passing ground? From what I've read, it takes 4 AA batts - perfect for a 5v or 6v BEC for power. If you remove the circuitry and re-arrange it for temp installation on a vehicle, it should be pretty light. Of course this only works if it has some type of hold feature so you can see the reading once the truck comes back to you.

GD: If you don't want yours, I'll take it off your hands to test my theory. :)
