With this you can project you POV's image onto a wall, ceiling, or pretty much anything!
It cost me nothing, it isn't very sturdy, but it does do what it is supposed to do.
Step 1: Materials
this does not take many things to make.
1. a POV (mine is Ladyada's MiniPOV 3)
2. Cardboard or something similar
3. A magnifying sheet lense thing. (i dont know the kind of lense it is, i think it might be a Fresnel, but I am not sure)
4. Elcetrical tape
Step 2: Cut the Cardboard
cut the cardboard to 2 pieces about 9x3 inches.
you may need to cut your's to different lengths depending on the lenses or you POV. so just try focusing the pov and lense w/o the cardboard first.
Step 3: Tape
tape on the lense to both of your pieces of cardboard, on the short edges of the lense
Step 4: Cut
a hole for the serial port (*if you're using the Mini POV 3) in the cardboard, so that the LED's are in focus
Step 5: Tape
Tape on the POV, like this
Step 6: Done
now wave it around and project stuff on other stuff!
