View Full Version : Looking for internal pics of V1 b4 pop.

I want to compare the V1 before pop's circuit board with the current one 3.818. I saw internal picture of the V1 on the net around 3 years ago. Does anyone have them. I want to see if they just re-flash new software to the circuit board, or put a new one in. There must be someone else that takes their electronics apart than just me.

Here's some pictures I took of it. I edited out the bar codes so Mike Valentine won't void my warentee and future upgrades.

Antenna (http://www.geocities.com/joop1987/v1antenna.jpg)
Bottom (http://www.geocities.com/joop1987/v1bottom.jpg)
Front (http://www.geocities.com/joop1987/v1front.JPG)
Top (http://www.geocities.com/joop1987/v1top.jpg)
Lens (http://www.geocities.com/joop1987/v1lens.JPG)
I found it strangs that there was a resistor glued inside the front lens by the radar antenna, but I'm not a radar engineer, just a EE.

(If pictures don't show up, try again later; geocities limits my daily bandwidth)

The V1 consists of seven printed circuit boards:

1. A main board with the logic functions, switches, and connectors
2. A laser board with six individual laser detectors
3. + 4. Two waveguide boards mounted back-to-back onto the waveguide
5. + 6. Two boards placed into separate shielded compartments of the waveguide
7. A counter board with LED display

If anyone happens to take apart their V1, carefully peel off the "VRI" sticker from the micro and take a picture, or note all of the numbers off the top. I would like to know what kind of micro is being used in the V1. I suspect it is Motorola, but would like to know what family...

Is there a hole in your lens joop?

In front of the front horn, there's a circle with a resistor glued to it.

ut oh! don't let Mike V find out you did this! I hope you were very careful with the screws and didn't damage them whatsoever...!!

He only mentions if you tamper with the serial number, he won't update it. Nothing says you can't open it :)

Oh, so thats on the inside? Because I notinced on the outside in a similar place a small circular what I thought to be a scuff. I guess it's related to this. Also, VR told me scratches on the lens won't affect laser or radar detection. How can that be?

Yes, that's the inside of the lens.

Thanks V1 Dave, I appreciate it...

That is one mean looking detector. There is nothing cheap about a V1 unlike other detectors

Jim,

That dismantle/reasemble was worth it.
I plugged it back in and it does not false on laser any more must have been a loose pin that connects the circuit boards. I did take it apart about two weeks ago, that must have jarred something.
I will have to test it more by driving by a speed sign to see if it stopped picking up multiple bogies on a single.

I would still send it out to VR just to make sure. You will get your money back so cost should not be an issue.

Wow... How 'intellectual' the forum used to be (in 2005!!) :eek:

You have just got the award for reviving a dead thread from the longest time ago.


We have had some 2 years etc, but 4... unbelievable.



I remember when I was a young buck back here in '05! Graduated from HS that year.

well seeing as it's already raised, why did they change the horn design? The first horn seems to look better built? Was it for cost savings or is the newest horn better? Mem-tek???

The best answer would be for GOL to do off-axis tests of the old and new horn designs to see how the two different designs perform.

So why is there a resistor glued to the lens?

The Professor theorized that the 0 Ohm resistor is to alter one of the antenna's side lobes in order to help make the arrows work more correctly.

Sooo, after the tooling for casting the horn was signed off on they noticed it didn't work right so they glued something they had lying around to the lens to correct it :eek:

Far friggin out...

I believe that the horn was changed or shortened to make room for the new larger laser diode next to it.

1.7 has an extra 1/4" on the bottom housing six laser diodes two of which are at a 45 degree angle.

STI seemed to have copied this older design but I believe STI has four diodes, some using the same 45 degree angle.

They probably wanted the easiest thing to cast and to design. I think that VR would rather it control the lobes 'precisely' how they want, rather then allowing casting tolerances of 0.005" come into play, plus a 'weird' design factor.


History repeats itself... over and over ;)
