I goofed around a little more with that [url]Fresnel[/url] lens. First, I made half-assed welding goggles by putting the lenses of three different 3D glasses at cross-purposes to each other.
With nearly all light blocked, I can look directly at the intense focal point as I fry some bacon.
Although that was as far as I got. It was actually kind of painful to hold the giant floppy lens out that long.
So this particular project is going on the back burner. Eventually I’ll get around to making a frame and a focusing rig, or maybe I won’t.
