I have a couple of ideas in the works, but I've been busy the last couple of days. Here's what I'm working on:Originally Posted by drait
I think the issue is that in some cases the Valentine can't pull the voltage down enough on the base of the transistor to turn it on fully, and it really needs to be on all the way, since 5V is pushing it for RS232 in the first place.
So, here's what I'm thinking:
-I'll try adding a resistor between the V1 and the transistor base, and then add another resistor between the base of the transistor and ground. That way, the transistor is always "on" until it gets a high pulse from the V1 to turn it "off". This might be the way to go.
-Instead of the PNP, maybe I'll try using an NPN. I would supply the 5V to the RX pin of the DB9 all the time, until the high from the V1 turns the transistor on and shorts it to ground.
OK, about police laser (I had to put in my 2 cents of course ):
Of course, for the best protection a laser jammer is your best bet.
Short of buying a laser jammer though, the V1 offers the best protection you can get against laser. In tests, it consistently out performs everything else in sensitivity and field of view. Detection of laser in most cases is kind of useless bacause once your detector alerts, the cop already has a speed reading. However, there are a couple of exceptions.
If you're lucky, the V1 will alert you when a vehicle ahead is targeted. Tests have shown that this is possible with the V1. Couple the V1 with VEIL, and it is likely the cop won't get a speed reading on the first hit, but the V1 will alert, giving you time to hit the brakes before he fires again at closer range.
