Hi,
I’m new here and am looking for some expertise in electronics modification.
Have you seen this new toy yet? (The Hot Wheels Radar Gun $30.00 at Toys R US)
Apparently it is the 2006 “Toy of the Year”. I determined from its literature that it reads in 1:64 scale (S-Gauge) as well as 1:1. Does anyone here have the know how on how to modify the device to read in 1:87 (HO Guage) or any other for that matter? I think it would be handy to shoot the trains at any given point on a layout to determine their speed at any given time. I’m no circuit wizard, but would think modifiying the calculation on the chip or building an additional circuit to recalculate the reading wouldn’t be impossible given proper instructions.
Any one?

You could just measure the 1:1 speed and multiply by 87. Keep a calculator handy[:)]
That’s most likely the best answer. It could easily be designed to do what you want, but chances are really good the innards are only programmable once, if that, and that’s been done. It would cost more to make it reprogrammable, so that capability is almost certainly not there. Plus, you would need the stuff to do it with.
I have experimented with speedometers and eventually I came down to this point,
its all relative, Model railroading is to be fun.
If you use the gun all you have to do is perform a calcualtion and you should have your number.
60,6 feet is 1 mile in HO, divide by 10, and make 10 foot increment marks, run your train in 10 feet
time it then multiply the seconds by ten and use a speed chart to find the speed. It’ll be slightly off but not much.
I made passenger schedule charting based on this concept.
Of course if you use fast speed 6/1 clock is best, makes 10 feet a mile.
