Re: motorising off-the-shelf semaphore signals

Hi I would use a servo motor to operate a semaphore signal. Motors and controllers for Servos are readily available and one such supplier is Heathcote Electronics.. Demo video... http://www.heathcote-electronics.co.uk/PicSignal.htm Product details... http://www.heathcote-electronics.co.uk/ServCont....

Re: inspirations, for model bridges

Here's a strange structure I saw when on holiday: Whitehaven tunnel (northern end) Note the right-hand side of this picture does not show the true depth of the bridge, this is because I got two half decent pictures and spliced them (badly). http://img689.imageshack.us/img689/6929/whitehaventunnel1.j...

Which way round? (installing decoders)

Hello, One of the locos I'm fitting for test duties on my home-made DCC controller (Hornby R2529 Fowler 2-6-4) whilst DCC ready, has no obvious place to rest the decoder. I think that putting it in one of the tanks would make sense but this would require it to be held in place with double sided tape...

So it's another small improvement for a lot of effort...

crash preventinion with voltage regulators

Would this work?

The idea is to force the supply voltage below progressively lower levels as the train enters the siding for a reasonably realistic slow down even when out of control.

Nah, that's good!
I think the pavement might be a bit clean though

Re: What should I build? (OO Scale)

--> Mad idea: build a through station that has been cut off on left hand side by subsidence/flooding/landslide/wrong sort of leaves/broken down train/ cabbages this would allow you to run unusually long trains in a smallish station and the disaster could be modelled* in the space instead of the smal...

Re: motorised control knobs

Surely the knob could correspond to speed steps in the same way the knob on a simplish DC controller corresponds to average output voltage. i.e. knob doesn't represent speed but speed divided by maximum speed as defined by the gearing in each loco It wouldn't be a brilliant simulation, but it would ...

Before I attack a mouse, would an absolute position control with a modified servo work? :shock:
