I must like a challenge or punishment.
 
After the success of shortening three Bachmann coaches (Topic name ....Bachmann coaches how to shorten)
I have decided to shorten another baggage car.

This car has on board wireless CCTV to check on the quality of the scenery and a drivers view.
I will need to condense the electrics into a smaller area and keep it well ventilated.

Are you modellers interested in progress reports and pics as progress is made?
It's not a major project and will not take long, but might be interesting for some, as the CCTV is running on DCC.

.....cheers Peter.

Hi Peter.

In a word ... YES !

Mini-video is pretty good fun on 200mph slotcars as well !

The insides of the CCTV car to be fitted into the shorter car.

All components removed, the shell ready for the saw.

The digital readout unit is an adjustable Voltage controller for the 8.5 Volt camera,
and the six capacitors give 6000uF of storage,
to stop the camera dropping out on switches and to filter the rectified AC wave (DCC).

I hope it all fits back into the  shorter car.

A  Disclaimer ..... The components shown are from a setup installed a few years ago,
there probably is a better way of doing the same job these days.
I will leave that for the experts to comment.

Hi Jose,

The digital display is the Voltage regulator, it displays the output Voltage to the camera.

It's either change the 9 Volt battery often, or run with this large regulator that happens to have a read out.

As I said earlier with today's electronics there are better ways,
but I am from the days of valves, and they get too hot for plastics.

I found out the hard way, the camera is sensitive to over Voltage,
so the display is also a quick check of Voltage output.

...............cheers Peter

Hi Peter.

You could run a metal-bodied tankcar behind the coach...
...with the 5U4G inside ! :moose:

Not a bad idea Si.

But how do you arrange the 550 Volts and 5 Volts at 3 Amps to make it work?

I also think a tank car behind a coach may not be prototypical,
maybe in the UK, but not in Aussie land.

 :2t:

Decided to change the colour to match some other coaches.

Now to fit the camera, capacitors and Voltage regulator.

.........cheers Peter

Why is it that great minds think alike ???

I have just bought this on eBay, very James Bond,
but I had this silly idea that the camera being so small, it could be concealed inside a G-scale Motorman.

Powered by battery, but would not be a prob to power it via a DC to DC converter.

http://www.ebay.com.au/itm/151998793955?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

It's wireless or micro-SD card.

I also bought this one at AU$4.95, too cheap to miss and it has remote control !!

You are right, great minds do think alike.

The IP camera should work very well.

Keep us informed on how well it works, might try one myself.

If you use the converter, a few capacitors across the output will help to smooth out the power on points and dirty track.

The converter I used is a cheap ($8.00) one that works really well and is very adjustable for output Voltages from 5 to 32 Volts.

Good luck with the project :2t:

.......cheers Peter

I actually have a bank of super-capacitors onboard each tram, to act as a fast battery for the RC.

These little converters at 5 for AU$1 should do the job.

The camera head on those is 5mm Sq. and the video specs. seem reasonable for something that size.

They look good on the specs. and a good price.

They would be a lot easier to fit (too late now).

Thanks for the info Trevor.

All done, able to fit everything back in.

I fitted a switch to turn off the camera for when not in use.

You can see the camera lens at the rear door window.

.......cheers Peter

Not much has been happening with CCTV as it is working well.

Here is a pic taken with an old phone today of the screen on the 42 inch old TV.
Channel 4 is the output of the camera in the baggage car, on the left hand side is a painted bush scene on a wall.
 
Will post some better pics in a few days.

.........Peter.

Sorry guys, it's not a counter for a bomb,
it's a buck DC converter for the 8.5 volt camera and wireless transmitter.

Something tells me 20 volts DC will destroy the camera.

The converter was bought off the net, very cheap and very efficient.
The read out is the output voltage, the only issue was it's size, but it fitted (just).
