Hi Everyone and a merry Christmas to all.
For my last birthday, which was in March, my 3 sons gave me a video camera which can be installed inside a loco. The question I'm putting out to everyone is - Which locos would be suitable for the installation? I was thinking of the new TVG or perhaps the ICE 3. Any recommendations?
Regards

Hi Greg,
why damage a high value digital loco (drilling, and so on) if you can put the mini camera on an old, cheap and used freight car?
This is mostly done by the majority of modelers.
Merry Christmas to you.
Cheers
Renato

Hi Greg!
Don't go there!! Like John and Renato said, go for the freight car solution.
1)It's the correct thing to do;
2)No need to harm any loco;
3)You can atach the freight car to any train
Merry Xmas!

Thanks fellas.
I imagined that the leading part of the train was the loco, however, with your suggestion, I install the camera on a freight wagon and then put it in front of the loco. I'll do this.
Again, thanks for the tip.

Thanks Utkan, a picture says a thousand words. Fortunately, my camera is very small and the fittings are also small. The boys found it on the internet and it's made in Japan by RF System Lab - I haven't taken it out of its packing but around Christmastime I'll be giving it a go.

Greg You're most welcome Greg. I must admit that this idea was given to me by Micha,who is also member of our forum. So once again I would like to thank him for teaching this facility to me. Cheers, mehmet |

I agree in the advice to use a car, not a locomotive. My solution can be found here: Camera Cars |

I've showed this before, but since it is several years back, everybody have probably forgotten all about it by now  By use of a small mirror, you can make some alternate camera-angles, like this where I've created the appearance of hanging halfway out a window on the train. http://www2.ejberg.dk/external/marklinusers/onboard2.wmvAnd here is how I mounted the camera and mirror. Very simple:   Edited by user 28 June 2015 16:12:35(UTC)

Can someone please suggest a camera that is available in the US that can be installed on a freaigh wagon? I would like to get one if it is not too expensive. |

Very good, Mikael.
My favourite part is where you can see the train shadow. |

Here is an off-the wall suggestion, but it might be worth a try... There was a news report last week that the FBI is warning parents to be careful of the new Barbie cam. (This shows how sick some people are) That issue aside, it looks like they have, for some wierd reason, put a mini-cam and I guess flash memory, into a Barbie doll. From the pics on the news, it looks like the camera is very small. I bet you could cut the camera, etc. out of the doll and rig it into a train. Don't call me if you get questioned by the cops

I temperorily laid the camera and battery on 2 flat cars and ran it around the track. Picture quality is acceptable. It is a little grainy though. The transmit distance is not very good. I tried around 40 feet away, and the picture kept dropping. Works better when the TV is in the same room. Some times the picture flickers when the train is moving. Overall, not bad for 35 bucks. |

Excellent. Great fun factor. Some people dismantle the camera and build it into a loc. You can also improve the picture by changing the camera and get a separate TX, but again, then it starts costing money. I use a very sofisticated system for my RC airplane and fly it wearing googles from the ground for up to at least 1 mile away (called FPV). Excellent fun, but rather expensive. Have fun. /roger |

now that most digital cameras record good quality video, I am looking towards a solution that uses a small compact camera that saves the video to a memory card, thus removing the transmission issues and conversions. My camera is still a bit too large to sit on a flatcar and have room for a mirror to 'see' down the train. It does sit well on a 'Rollendelandstrasse' car but of course can only record video out the side. Some experiments in the Bw yard show promise so I think ideally we need a tiny camera that records to memory card for the best quality. Of course if you want realtime video you do need to transmit. |

I have tested such a camera, and it isn't bad at all: http://www2.ejberg.dk/external/marklinusers/onboard3.wmvIt's nice to be able to record in 1280x720 now. It requires a fair amount of light, and I still need to find a way to improve the white balance, but this is way better than the small wireless cameras I've used before. For this video, I've used a FlycamOne HD 720p: http://www.flycamone.com/It has a rechargeable lithium battery and a slot for a MicroSDHC card. It can record 80-90 minutes per charge. It is meant for RC airplanes, but it sits nicely on top of a flatcar too. Unfortunately, it doesn't look like there is an easy way to adjust the focal point. Edited by user 28 June 2015 16:12:52(UTC)

Mikael, I will have to wait to get to a windows machine to see the wmv file, unless it is also on youtube (and thus converted?) Edited by user 15 January 2011 20:54:42(UTC)

No, I'm not a user of youtube (yet). Is there another HD video format that you can see? I should be able to render the video to most of the common formats.

I viewed it on my wife's windows machine... very nice good quality video. And yes, the focus does need to be closer... almost there !!! |

Hi All
Just build a camera wagon very simmilar to the one Mikael has made. Just one question. Does anyone know a good way to transform and supply power (9V DC) from the tracks?

Hi, the converter has been built by an electronic laboratory on my request.
Sorry I cannot help in this matter.
The quality of the video depend by the camera mounted.
I've payed about 20$ for camera and wireless transmitter, you can understand, it's quite different from my Märklin set 49940. 900€ |

Very nice cameras, folks.
I see that I have to renew my camera, as the quality is poor.
A voltage regulator is not so difficult to build. A bridge rectifier (or four identical diodes) to convert AC to DC, then a 7809 voltage regulatur to reduce the voltage to 9 volts (max. input voltage is 35V), and a big condenser to smoothen the output voltage.
A cooling fin may be required for the 7809.
I made a 5V regulator/charger with a 7805 (78 = positive voltage regulator, 05 or 09 (or others) = output voltage) for my camera car this way. It works perfect with a cooling fin. |
