If you've got some know-how and a little time on your hands, this DIY tutorial from DIY Perks shows you how to build the "Sun-Blaster", a portable and powerful 1000w LED light that doubles as a spot and flood, complete with dimmers and battery/AC power -- all for $40.

This build is not for the faint of heart. It's going to take a bit of time to not only build the thing, but to gather all of the materials, so if you're looking for a quick no muss no fuss activity, you might want to pass on this one. However, if you're looking for a fun weekend project that will result in you having a powerful 1000w LED flashlight, this might be right up your alley.

Now, obviously you're not going to find the materials you're going to need lying around your house. You can find the material list here (complete with links), but just a few of the parts that go into building this thing include a voltage booster, a CPU cooler, and a 10k Potentiometer -- whatever the hell that is. 

The great things about this light is that it's cheap to make, it's portable, and it's powerful enough to light an entire outdoor scene, as well as delicate enough to serve as a hair light. 

What do you think about this DIY LED flashlight? Could you see yourself using something like it on your films?
