Step 6Pinhole
this is a very simple step but it can still be messed up easily.
try several different pinholes until you get one you like
the idea is to make a very tiny hole {as small as possible } in a thin bit of sheet metal.
in this case aluminum from a coke can sheet .brass shim stock makes the best pinholes but i dont have any.
carefully cut the can apart and cut a 2 inch square sheet from it {blood zone for the less handy among us wear gloves}
the trick to making a very tiny hole is to put your 2x2 square of aluminum of an firm surface then use the smallest sewing needle you can find very gently push the point into the center of the 2 inch square of aluminum but dont break through yet , gently spin the square around so the hole is small and circular.
if you can just barely see a spark of light when you hold it up it will work.
tape the square over the hole cut in the cover
now its finished
