I really like taking macro shots. There's a problem though, without the proper lighting macro shots are really hard to take. You have to use slow shutter speeds, a tripod and can't use your flash becouse you get ugly shadows. The solution is using a ring flash or ring light, but those cost more than 60 dollars. I wanted to get a ringlight for less than 10 bucks, so I started searching around and found a couple of sites that served as inspiration for me to build my own ringlight. metku.net/index.html naturemagnified.blogspot.com/2009/11/make-diy-macro-ring-light.html
Those lights are really good, but I took a bit from each of them and used some of my own ideas to get a different ringlight.
I hope you like it
First of all, we need: -48 LED UFO camping light. I bought mine from ebay (search for "UFO camping light") for about $7 including shipping. This will be our ringlight. -58mm UV filter, or whatever size you want. You can use a broken or old filter, we really only need the threads. I bought a new one from ebay for $2.50 -4 AA battery case. This will power up our lights. I bought it locally for about $1.
-Car cell phone charger with coiled cable. I had a broken charger, so I used the coiled cable for this project.
-Cell phone charger or AC/DC adapter(Optional). This will be our alternative power source. The one I used came with a bluetooth headset. -Round food plastic container(Optional). This will be our diffuser. It must be round, transparent and the UFO must fit inside it. Just $1 on a local store.
-Heat shrink tubing or tape
We also need a solder and a cutting tool.
The battery case I got had connectors like those 9V batteries, so I got a couple of those connectors as well.
