Relay as N-scale switch motor. Part III

The relay chassis issue is solved: Just cut out a diamond shaped opening at the position where the wire should come out.
On this photo the cut is too large, but it was the first cut. ;)

The next needed idea is how to mount the relay as under floor switch motor.

Relay as N-scale switch motor. Part II

Today the wanted relay type arrived and I found copper-plated steel welding wire ø 0,8mm in the local hardware store.

The long side of the L-shaped wire is 55mm of which 5mm is soldered on the relay armature.

Now I only need a good idea to get the chassis back on the relay...

BTW: Only one output is needed instead of two for the commonly used dual coil switch motor.

Relay as N-scale switch motor.

Last saturday I was surprised by such a nice and simple idea to set N-scale switches that I wanted to experiment withthis by my self.
Not all I needed I had at stock so I had to make some compromises.

The parts I used for the experiment:
  • N-Scale switch undone from the original coil driver
  • Bi-stable relais (shouldbe a normal type)
  • Paperclip
  • DC model railroad Transformer with throttle
I did bend the paperclip in a L-shape and soldered it on the relay armature after I had removed the plastic chassis.
After drilling a small hole in the center of the throw rod I inserted the paperclips short side into it.

No it was time to do the test.
With the relay connected to the transformer, and the switch to the relay, I turned the throttle to about 10V...

Yes! The switch was thrown by the relay!

I like this solution. The relay costs about 1,60 Euro and can also be used to polarize the electro frog of the switch.

Rocrail "Team-Day"

Yesterday, March the 26st, we had a Rocrail Team-Day in Venlo hosted by the MGV.
After a warm welcome we were invited to view the marvelous 1:160 layout, controlled by Rocrail, from Sjaak. We were all very impressed of what is possible in this small gauge and by the many DIY parts and details.

Next we had a long look in a big engine shed located in Blerick with astonishing Locomotives, wagons and all kinds of 'BIG' parts.

The impressions of the afternoon made us hungry which we did satisfy in a Chinese restaurant.

BiDiB Weekend

I received test BiDiB hardware from Wolfgang to implement the BiDiB protocol in Rocrail.

In short this piece of hardware is an occupancy detector capable of handling current- and RailCom detection. If the CS can handle POM and booster cut-outs it can also be used to read CV's on the main.

The implementation in Rocrail has already reached the state of usability, and it makes fun to work on it.

I'm sure BiDiB will be widely accepted in the model railroad scene.

SmartFred

No one seems to be interested in a SmartFred to complement the existing wired Freds.
The big advantage is obvious, but model railroaders love there cables and plugs. ;)

The prototype brought some new controls and ideas which can be used for andRoc; The new slider control already replaced the Android ProgressBar.
