Oh, that's nice. I've been dreaming about this very thing. However, I also want status so mine needs to be 2-way. I've been thinking about Bluetooth tranceivers. James

Hi guys,
Just thought you would like to look at a little project I have been playing with over the last few months.

The body is a bit rough, as is the home anodizing but I'm pleased as a first effort!
The body houses 2 triple XPG's from Cutters and I run it from a 11.1v, 3000 mAh Li-polymer battery either on back of the helmet (quite heavy but not too bad!) or in the camelbak.
In a pocket behind the LED holes are 2 of George's BFlex drivers wired to run as master/slave and each driving one of the triples.
All pretty standard stuff. The slightly novel bits are the wireless remote control and handlebar switch.
The ugly little circuit board shrink wrapped to the cable is one of these from Farnell's. The handlebar switch housing was milled from nylon bar and houses one of these along with a couple of watch batteries.
The range is quite good considering the tiny size of the transmitter and easily works from the handlebars and can turn the light on and off from across the other side of the pub after the ride!
Just in case something goes wrong with the remote there is also a reed switch inside the case which can be operated with a small magnet.
I have used it on a number of night rides and having the ability to turn it on or up without removing my hands from the bars is great, as I tend to ride with it on the low setting (500mA) and only go to the 1000mA setting when the trail gets a bit hairy. It also comes in handy to flash the occasional car should they not dim their lights on the way home!
I would like the beam to be more narrow though as the spread on these is very high and it's really more suited to a bar light.
(Sorry about the quality of the photos!)
