The Fresnel lens is a great idea. And it doesn't have to be expensive - those plastic lenses glued in the back window of RVs to increase the field of view are Fresnel lenses! Just aim your light through in the opposite direction (from outside the RV to inside - to convert divergent light to near par...

I've heard of many famous person sightings at BRC (none myself), but not performances... Unless you count Bjork doing stand-up at center camp. I heard this happened in 2003 or 2004, but it could be me taking a joke seriously (it's happened before, it'll happen again). Can anybody confirm?

The level *should* be on the side of the battery. Usually the problem I have is seeing the water level through the side of the battery. You need a good light to 'candle' the contents well enough. If no level indicated on the outside, my best guess is to make sure the metals are covered... I've not s...

I have only seen them hand made. It seems like the flame can respond as fast as the valve. The limitation may be in how fast a valve you can get. I saw the ww2 hardware on the discovery channel. Actually, to my understanding, you can actually have flame be a speaker directly; valve speed would be i...

It also depends on where on the dome the force is applied. In T'dome, folks are climbing all over it.
