Tell us about yourself!
As mentioned, I used the video (top of instructable) as inspiration. I used the parts mentioned in it. There is a Google docs link to the parts.
I understand what you are saying, but it works for me. It gives me a nice soft light for the setup I used.
Thanks. The purpose was not to build a flashlight with a spot, but rather one with flood, to use for photography. The 2, used together, works well in a small studio setup. I do own a Nitecore TM26 and a TK75 for real flashlight purposes.
Wow!! I did not see yours in all my searches. Yours looks much better than mine. Love it!!
The parts are listed in the link, at the top of the instructable, that inspired me to build this.
As you can see from the pictures, I used a battery from a PC UPS to test with. For portability, the battery pack I build, with 18650 batteries works best for now. I will be looking into LiPo batteries in the future.
These are the ones I bought.http://www.ebay.com/itm/161473769064?_trksid=p2060...
My cost are probably a bit higher since I bought new heatsink fans, grills, wire connectors and the voltage meters. I still consider it cheap for what it delivers. By using old laptop batteries (LiOn), I don't need to buy expensive batteries for now.
Without the need to buy a heatsink, LED mounting bracket or battery, it works out just under $50.00 for each flashlight.
