Exposure depends on your pinhole size and focal length. Take a look at: http://home.netcom.com/~lfratkin/calcpinh.html This will give you an f stop for your pinhole. Then just use a meter to determine exposure time and refer to this page: http://home.netcom.com/~lfratkin/Exposure.html
Pinholes are generally made with brass shim, but I have had success with aluminum from pop cans (sides, not top & bottom). Drill the hole with a fine needle. Determine actual size of the hole by measuring it through a loupe. You can see some of my images at: http://www.members.home.net/pegan14/eps/usa/ob/ob01.html These are made with a large coffee can & b&w paper (my "coffee-can-cam"). Good luck.
