TRAFFIC LIGHTS

[Bahco]

At the very least get them switched by relays so that your littleun is only switching say 12v or less, I'd recommend SSR's controlled at 3 or 5v.

Good point Tim.

How would I transform down to 12 volts?

with a transformer.

but that is a problem since they are ES fittings you will probably have trouble getting 12v ES lamps that are bright enough.

hence my suggestion, bolt them to the wall and use mains lamps, but you are still going to need a controller

Have you a link for a controller pls

I'm just building it as we speak.

Top guy. I'm just on the M6 driving up to Leeds.

I shall be in the pub at the end of my road when you get here.

Buy me a pint and it's all yours

 

[Bahco]

You are very cheap

 

[RF Lighting]

Funnily enough, you arn't the first person to say that

...............But first of all you need to get clicky and make it up, it does need soldering, but it does come with instructions.

same one as before. since its cheap, reliable (moost of the time) and easy to build

but since RF has offered.......................

you could use a PLC controller but they are not cheap

Rf are you really making it? if so, how about put some triacs on it, switched by the led out put, that way it can then switch the mains lights

i'd be a bit apprehensive of a 5 yr old playing with light switches with 230v across them.

So what voltage are the domestic light switches in your house

Or are you thinking of something like this...

Don't see why not.

Can anyone tell me how to do this, and which triacs I might need?

I'm no electronics master. I can just follow simple diagrams and build velleman kits

Also found this if anyone is interested

I'd suggest using Solid State Relays AC mains rated output DC Controlled input 3V run from a battery source say 3V

Mains wiring will depend on the lamps used, suggest 15W ES pygmy unless the SSR's need minimum wattage to run properly or the rating advised on the lampholders higher wattage may make the traffic light hot to touch though?

You can also use mains rated SSR's to switch AC as low as 12V or even lower on the AC side so you could convert the lampholders to accomodate a lover voltage lamp.

With space the SSR's and battery could be mounted inside the traffic lights? and a multicore(4 core) out to the switches carrying the 3v making sure you segregate the mains wiring from the control wiring.

You'll also need robust switches or pushbuttons(possibly latching?) as they are likely to get some abuse.

If you dont want to go down the Mains voltage route then id suggest removing the lampholders and replacing with Leds and associated circuitry

A lot of my switches at home are X10 controlled no need to touch them

Take one out of an old stacker system/twelve volt tv
