I'm after some help with making my own LED light stick for light painting, preferably one that can change colour. I'm technical minded enough to wire it all up but I just don't know what to buy in the first place to make it:thinking:. I was thinking along the lines of those flexible led strips, like this http://www.ebay.co.uk/itm/251281555...96181478&tpos=unknow&ttype=price&talgo=origal

It comes with everything to run off the mains but I was just going to modify it to take a 12V battery pack. Will this set be ok for me or am I looking at the wrong type of LED and set up?
 
That will be fine, keep the 12v-12v controller and colour box, pop to maplins and pick up a 12V battery tray for AA batteries, they also sell 2 pin sockets so you can solder the 6mm socket to the 12v battery tray and you'll be sorted ;)

Cheers. Maplins is my second home lol. I can wire up a lot of different things but never used a kit like this so I was if it was what I need. It will be a trip to my local DIY shop for a bit of dowel rod to hold everything. I'd imagine these LED strips I should be able to cut it to length if they are wired in parallel, I would have thought so anyway for running on 12V.
 
You can cut most of them to length. Worth looking at aluminium channel to mount them to - e.g. curtain track. A diffuser like tracing paper not a bad idea either...!

They're in series...If you add strips you have to up the amperage of the power supply. Instead of cutting/soldering to make turns, just fold it. Two 90* folds and you've got a 180* turn with one strip right next to the other.

I made a DIY ring light using the bright white variety: http://photographic-academy.com/tips-and-tricks/99-tips-and-tricks/127-tips-and-tricks
 
Wow. I like a lot. Going to trawl ebay for the LEDs but that is a great idea!
 
Ordered and paid for:beer:It will give me something to tinker about with on a rainy night.

Great idea! Apparently you can cut the kit every 3 LED's but I think I will stick to what you said and bend it. If I slightly off set them when I bend it round on itself there won't be such a gap between the lights in the image if, hopefully it will look more like a solid stick.
