Alot of this could also go into the disaster planning part of M4C, but I thought this would be more fitting.
This guy Kipkay has come up with all sorts of really interesting modifications to things around the house, or things that can be found easily at any department store. Alot of these are novelty items, but none the less make for a fun watch.
Things such as build your own Night Vision optic, Guard dog burglar alarms, computer mouse stink bombs, Boosting the range of any remote, Cheapy Lighter laser burner, noise eliminating headphones etc.
Spent the last hour or so watching every single one of these, awesome stuff!
