These are a few ideas I have for useful DIY hardware projects.

Pulse extender – inline unit that takes a single short pulse input and has a longer (variable, controllable) pulse output – for slow switches or servo motor controlled items.

Digital Lighting – coach lighting with digital level control

Switch Controls – digital switch control on a budget.

Braking Section – a smarter approach to a braking section for signals

Booster – Booster with MFX feedback built in.

PC Control – PC connectivity for direct control of trains and switches etc.

    Thank you, on your generosity in sharing your ideas. Really grand of you indeed. My question is will these work on Marklin 3 rail digital.

    Once again thanking you

    Hi Suba,

    These ideas are indeed for Märklin 3 rail. I wrote this some time ago and I think that the mfx capable booster has been released by Märklin already now. The other things though I have still been thinking about, especially the smarter breaking section for signals. I would like a scheme where the train slows down through digital instruction on breaking sections if the signal is red. It is tricky though to ensure that a train will stop before the signal under all conditions…

    Cheers! Dave.
