This is my first Instructable, so I hope its clear and concise enough for you all, I hope it helps you all too.
Requirements: What I wanted to achieve was colour accents in some of my pictures, either in the background or just a stream of light entering the picture, I have an old 4 channel light chaser laying about, and an old 4 way dimmer switch, so I thought Id try and solve my problems using this. If you dont already have a chaser you can pick them up very cheaply on eBay, you could always pick one up from a boot-fair, wouldnt be that expensive, and doesnt matter if it doesnt work either, as long as it has the bulb holders.
First of all, you will need to make sure you have:
4 Channel Light Chaser;
Plasterboard back box;
4 way dimmer switch;
Bulbs, if you dont already have them.
An angle grinder will save your arms, and time, (I used one of these) however a saw would be fine,
An electrical screwdriver,
And whatever screw driver you need to dismantle the chaser (mine was a No.2 Phillips)
Step 1: Rip It Open
Step 2: CUT It
Step 3: BEGIN Building
Step 4: Connect the Cables
As you can see from the pictures its a very simple wiring job but as this is mains electric if you do not feel comfortable or youre not confident, please consult an electrician, if you are confident and you wish to use this outside your home you will have to get this PAT tested (Portable Appliance Testing) please make you sure you do this any way to protect yourself and others.
Step 5: CLOSE It, TEST It, USE It!
As you can see my son decided my son wanted to check them out!
Something worth considering is this could be run off a 12v inverter, so as long as you do not draw more than your inverter can supply you can use this out and about with your car.
Hope you enjoyed and this is easy enough to read and follow.
EDIT: I have taken a few demo shots of my son's Yellow beaker, hope you like
