V1 Virtual Display : Valentine One to PC via USB

**zPilott** · 04-20-2005, 01:28 AM

I have been working on this for quite some time, but I have finally finished it. After abandoning the serial interface for several reasons I came up with this:

There may be some enhancements in the future, but for now this works great.

Connection:

The parts list for the connection is:
2 10k resistors
1 15k resistors
1 2.2k resistor
1 .033uF capacitor
1 +12V to +5V regulator (e.g.) 7805A
1 2A2904 transistor
1 USBMOD3 (the best price I found was at http://www.futurlec.com/USB.shtml )
A 4 or 6 conductor modular phone jack (or you can rip apart a phone cord)
A small enclosure (such as this ) to make things neat.

Look for the thread on the accompanying software in the software forum.

What does it do?

The valentine 1 is a radar detector, a very popular one... this displays its output on your carputer.

I'll have a look at that then

Awesome work zPilott!! I'll have to see if I can make this one work with my V1

Does the concealed display need to be attached in order to get the output signal?

Thanks for reminding me, I should have said this before. The current design works ONLY ON ITS OWN!!!!!!

DO NOT CONNECT THE REMOTE DISPLAY

(sorry about that, just wanted to make it clear that running a splitter and connecting the remote display MAY cause problems

)

I am working on modifying things to allow for that, or for putting an in and an out jack on the board for connecting the remote display.

That's what I figured... just wanted to make sure

You can do what I did on one of Jim's designs and just put in a 2-pin jumper or single position DIP switch inbetween that resistor and +12V (or in this case, +5V). Not as elegant as an input/output port, but it works.
