    My head hurts!

    Man, I just decided I need a new light and wandered into this forum. Some lights look impressive, and I want to try making one. But after reading for the last 30 minutes or so my head seriously hurts!

    Any advice on a good place to start ...so I can jump right into this light diy stuff? Maybe I missed something about beginner stuff / lessons.

    Thanks for the help!

    and search for the "DIY Dinotte" threads.

    It's not about speed, it's about lack of control.

    If you want to jump in with both feet and have some electronics knowledge (just the basic stuff, or want to learn), you could check out light that Deesta has built and sells the housings for. That light would probably blow away whatever you have seen in the stores, if you set it up with 3 x Cree MCE LEDs. It would require basic soldering and some of it is small, but does not look too bad.

    You did not say how much info you need, but IMO, to build up lights you will need some basic knowledge about series and parallel circuits and also how to measure voltage, current and resistance using a meter. You should also check out the simple ohm's law (voltage = current * resistance) and power formulas (power = voltage * current). You could probably build a light without this info, but if there is a problem it would be more difficult to figure out. Here are a couple places with basic electronics info:

    This site also has a lot of info and interactive lessons:

    Light kit?

    All, thanks for the help. I will do some reading and report back!

    I also got a msg from a guy selling complete light kits. They look really nice and super bright so may be a good option for me. I want to see how much it would cost me before buying a kit though... maybe will invest more time in book study if that will save me a ton.

    Thanks, bottoms up!

    Go to bikeled.org as yetibetty said. It is one of the best step by steps around, and you can substitute the most current LED's into your build. If you have questions along the way ask here or Allen directly.

    Otherwise several of us sell our stuff too.

    I just finished my first build a few weeks ago (first three actually). I spent alot of time reading a number of posts, many of the ones mentioned above. These were great sources of information.

    I ended up poaching ODtexas' design (w/ a few modifications). It worked out really well and I think gave me a good base for more ambitious builds down the road.

    I would recommend practicing some fine soldering before you go to work on the actual LEDs though. With the 10mm xpe boards, space is really tight and very easy to mess something up.

    good luck.

    On the kit topic. If things don't work out, I can also hook you up with a kit or built light. Check out http://classifieds.mtbr.com/showprod...?product=35825 for more info.

    Thanks ~Chris
