    Well, Shamus, I've been trying to put the trains on hold for the summer, but you keep giving me new things to try.
    Thanks for the diagram, I'm off to Radio Shack on my lunch hour tomorrow for the components.

    Guys,

    I was out shopping yesterday at my local electronic shop. Found these two fabulous books ($2 each) containing circuits for everything to do with model trains. Let me see:
    Air horns, Capacitor discharge, crossing boom control, crossing sound (bells) flourescent light simulator (blinks your light on and off when swithing them on, like real flourecent, even set it to "broken" mode) light sensitive train detector (senses the shadow as the train passes over) light sequencer for shop fronts, or road works warning sign (the large animated arrow) Pedestrian crossing, including the button, dont walk/walk then lights change, wait then dont walk comes on then light changes back to green. etc etc... Cost of each unit to make is no more than $10 Aus ($5 US) or circuit boards only (you buy the parts) for $2 US. Tunnel stretcher (detects the presence of a train, turns power off for a preset time, then power on again) Good for delaying trains in tunnels to give a realistic travel time. All sorts of goodies. Shamus, Do you want the "bell" circuit for your crossing?

    The "light sensitive" detector would be good for controlling crossing lights etc, as it detects the train when it arrives and stays "on" until the train has completely past that point, not when the electrics of the engine are at a particular point.

    TOOT!

    try http://www4.tpg.com.au/users/talking/
    then kits, electronic kits, modelling. List and prices of some beauties! I have the book with all the circuit diagrams, if you wish to make your own.

    TOOT!

    I built a flasher unit for my flashing crossing lights, thought you might like a copy of the diagram, so you can build your own. Cost (Very cheap)

    Hi Woodie,
    Yes I would like the Air Horn & Bell diagrams/parts list, can you post the daigram here please.

    Thanks

    Shamus,

    Try these. I have the airhorn kit (circuit board and components) but haven't yet put it together.

    When I make a post, the HTML flag is "off". How do I reset that to "on"?

    TOOT!

    Shamus,
    You may have tried while I was editing the message to get the URL right. Should be OK. I tested it when finished editing it.

    TOOT!

    Shamus,

    I have made the diesel sound generator that sits inside the locos. Sounds great. rasies and lowers with the speed. However you need PWM controllers for it to work. Detects the back EMF generated by the motor to determine the revs. There is no steam one, however full DCC with sound decoders provides that. Good luck. Need to know more, let me know.

    TOOT!

    Shamus,

    I'm no electronics wizz, but you may be able to adapt the bell to your flasher unit. It is designed specifically to run with the crossing flasher provided in the book. This crossing flasher is auto detect and uses photo sensitive switches to automate the
    on/off.

    TOOT!

    Thanks Woodie,
    Now that I have then saved to HD, the next problem is building them sometime. All I need now is a sound chip to put in the loco.
