Only takes 5 minutes- see my earlier post :)

How long does it take you to drink coffee? I haven't soldered for years

I built and tested the kit in about 20 mins. The kit is easy to build, I'd build it and test it before modifying it

So with such a device, could a suitably informed person make it power a relay when over the speed limit? The device must have speed and speed limit information. This could usefully power some IR LEDs...

I don't think that gatsos are too much of a threat, what with them being fairly visible. I reckon the main danger to license is the sneaky pig behind a bush with a laser gun.

Thats kinda what the mod does - 2 second alert when in the zone and continuous alert if exceeding the limit.
Then again, IR leds are low power, just leave them on all the time if you think they will help

Aye, but scamera vans won't be on the GPS database, and they are the really sneaky ones.

OUCH!!

That's ok, I didn't really need that skin on my arm anyway

Re: Inforad siren modification
 

What box did you get? The relay is too big to fit in the T2 box I got

Re: Inforad siren modification
 

not sure, but it was too tall for my box too, but having trimmed all the component legs and filed the top of the relay box it squeezed in. Shame you made the same mistake though....

My 2.2uf capacitor doesn't have direction arrows on it. It has a long and short leg. Which is positive/negative?
And what's what with the TIP 142?
