Can any one help me designing a light chaser circuit? BEST ANWSER GETS A PATCH

I am Made/making ( i've made one so far ) some Par cans (DJ lights).
I would like to know how to build a circuit so the lights can chase each other (chaser circuit). At the moment the lights plug in to the mains and require 230v and 50w to power them.
I want the circuit to be safe and I would like to also know what gauge wire I should use.
I would like the cost to keep below £20.00 because that would exeed store bought prices.

Thank you

How many will there be ? I DON'T recommend you try this without isolating the circuit from the mains, so each channel needs a MOC3020, a couple of resistors and a decent triac, driving it all would only need a couple of cmos gates, and the ubiquitous 555.

There will be two lights. I was thinking the circuit not all the components would with stand thaat current.
Are you sure a 555 timer will withstand that current?
Do you have any other solutions

For two lights, you might make it under the 20 quid mark. Build a two transistor astable like this

Replace R1 and R4 with the inputs to MOC 3031 optoisolators and a couple of triacs

That looks do-able for under the £20 mark... I will have to think about this. As store brought prices are not that much more and they are better quality....

Sunscreen will consider three hundred dollars to make good use of many kinds of sunscreen agents to compound, the other enhanced adhesion, better sunscreen consequences, such your sunscreen occhiali da sole ray ban 2012is the best choice of facial applications. And then your five or six hundred or thousands of sunscreen, sunscreen effect only two to three hundred of the poor, soon after, zero male only brand positioning is more expensive but from the price, he thought do not need to invest in less expensive sunscreen.

In the Abra electronics catalog there are light chasers at 20.00 us money.
they would need a converter to your volts. I built one at 110volts. worked first time at 200 volts per circuit. I am a newbi to electronics but you should investigate. Uses triacs and has good instructions.

Here is one of my instructables, it uses a 4001 quad nor gate.

That's a fair amount of current, I'd think of relays, and transistor switching for those. Price up relays first?

oscarthompson (author)  lemonie7 years ago I Might get these and then just buy my own spotlights.

I was only messing around in my shed with light fittings until I came up with putting a light fitting in two golden syrup tins (joined together).
It would be nice to build one, but at 25 quid to buy you wouldn't save much (if anything)

Here goes the basic circuit, Instead of Leds they can drive Relays that way you can drive the lights off of Mains Power.
