I’ve come up with a few little DIY items and documented some other ideas that I use.  Have a look around.

• the JOEgo
  a little lighting setup for mini studio work

• Fruit Snoot
  A nifty use of the foam stuff you find in the grocery isle

• Canon BP-511/A Dual Battery Holder
  use a plastic Sucret box and some foamies

• A mini tripod my dad permanently lent me
  Vise grip with some 1/4-20 studs on it
