I am hoping to be able to apply a silicone or urethane layer on the underside of the flattish area so that it won't slip in use. We'll see how well that works.

Helmet Mount v1.0
Here are a couple shots of the helmet mount so far. Again I'm not sure how the rigidity will be with these dim's until I see it for real. Now I just need to do the bar mount and then send away to get them. So far these are around $10 bucks a piece. Not too bad for 3D prototyping it seems to me.

Head Mount v1.0
I am finding a bit of time to put into the light project and am working on various mounts for the lighting unit shown in the previous post. It is mostly just some time on Solidworks.
Here is a picture of the 3D model as it stands for now. The thin connecting parts are designed to flex and allow the mount to conform to the shape of ones cranium while still providing a solid and stable support for the light. We will see how well my guesses at thicknesses turn out and most likely need at least a version 2.0. I have uploaded it to Shapeways and will order once I have made a helmet and bar mount as well so I can save on shipping charges. The other mounts shouldn't take as much effort or time.
Here is another screen grab from the assembly model in Solidworks. All the detail has not been modelled on the light as it has so far not been necessary.
I will continue to post more as progress allows. I need to get out and ride my bike a bit more too before the snow flies.

Manufacturing Project
Here are a few shots of my current project where I get to exercise my brain. It is going to be a lighting system for biking and skiing. It will be completed in collaboration with brother Cam who is working on the electronics end.
The first shot shows the cooling area at the back and the LED cluster mounted in the recess without any optics other than just the clear acrylic cover for protection. All of the circumferential holes are just for lightening and hopefully they don't slow down heat transfer too much.
This next view shows the back with the lightening holes in the cooling fins and the front with the 18 deg. spread lens in place behind the acrylic cover. The screw sticking radially out the side will be for mounting the unit to a helmet or bar mount.
The overall dimensions are 30 mm in diameter and a little less than that in length. In operation so far it gets too hot to hold but not too hot to touch. I think that it is not yet working at full power as the voltage of my packs is a little less than ideal for the buck puck regulator that I am using. Anyway further updates will come as advances warrant...

Lookout Bambi!
This is just to show a few photos of the mountain bike transporter (my car) after an early morning run in with a deer.
Tuesday morning last week under the growing glow in the eastern sky on a dark country road south of Barrie, I had a deer run out in front of the car from the left. I managed to slow before an unavoidable impact that sent the deer off to the right towards the ditch. It was a real surprise that initially left me wondering if it had indeed occurred. After a couple hundred metres, my buckled hood confirmed my suspicions and I pulled over in the darkness. While the damage was extensive, there was no rad fluid leaking so I carried on to school and then later drove the car back to Barrie to a local body shop. There was no sign of the deer other than the hair left on my license plate holder so it's fate remains unknown.
$5600 later I am due to get the car back tomorrow. That will be great as I surely miss the hatch back and bike rack. The Hyundai Sonata that I got as a rental was okay but not to my bike related tastes. The trunk would barely hold a fully dissambled hard tail. - Weak sauce...
Below are a couple pictures showing the front end damage.
At least it enabled nice easy access to fill the wiper fluid.
That there be deer hair...
Maybe through some miracle the deer made it out alright but I suspect otherwise. In any case my advice would be to avoid large mammals when piloting a motor vehicle as they can do some real damage.
