Oh, I get it now. I wasn't quite sure what you meant by IR booster. That's really neat!
Yeah I have one, but mine is not battery operated. So yours is really handy!
Do you find that the different frequencies work better/worse with your camera?
I have a 100 pack of IR LED's I bought off of Ebay a few years ago, just never had the patience to put them together. I was playing with some designs at the time. I purchased them for my outdoor cameras.
Great idea there, I'll have to start trying them with the DiMage camera.
