new bike light

[kfong]

I got mine a couple of weeks ago from dealextreme. The 3 mode version. It works great on the trails, blew away my 3watt led. No comparison. Going to put a second one on my helmet. This is one very bright light, makes trail riding possible at night.

After my first real night ride with a Walmart special headlight, I cleaned out my underwear and found the reviews for the Magicshine. I just installed the lighthead that I got from Geoman, and was wondering if there are any lurkers out there that have come up with a clever way of mounting it. I found a while back on another EV forum that ti.com will send you free samples, but not sure of what the requirements are. I use a university email address and haven't had a problem so far. I am using a 30w 36v-75v dcdc converter from them, and have it setup to output it's max rating of 5.5V inside an aluminum project box I got off of Ebay and cutdown to fit the power supply. The lighthead draws about 2amps max(.25A from pack after converter) and will operate fine down to about 5.4V (although power led is always red of course). After that it gets a bit flaky. Tomorrow will be my first real test ride with it but not expecting any issues.
As you can see from the pic, I have my power supply box mounted below the lighthead with some zip ties. I am thinking of mounting the power supply box onto a handlebar mount that swivels,and mount the lighthead on top of that. Any ideas?

fuz,

If you have some old light sets, look at them to see if you can cannibalize their mounting systems. That's what I've done. I had a nice slide-in, slide-out mounting system on my old lights that click when they're locked into place. I put the buttom plate from one of the lightheads on the Magicshine. It works well, plus it didn't cost me anything.

Heh dude that's so ghetto :lol:

Yep. But on a bike like mine, calling any one part of it "ghetto" is meaningless. :lol:

For those interested, this is the preliminary version of the instructable. If you see I missed something or any errors, let me know so I can revise it.
