Built out of an IKEA Bjurön plant pot (now no longer available, pity had a few more ideas using this pot), and a Sinar 4x5 back. Shutter and pinhole mounted internally. Shutter design pilfered from others on the net, a sliding opening sprung loaded, actuated by a locking cable release. 118mm focal length, 0.400mm hole, f304ish. Daytime shots on EI 100 films range from 8-30 seconds depending on reciprocity (sunny 16). Shadow shots from 30 to 200 seconds. Not tried night shots yet
