In a recent e-mail, SurvivalBlog reader SF in Hawaii mentioned an inexpensive and portable intrusion detection system: Get a few Radio Shack ‘Portable Motion Detector Alarm/Chime‘ devices. (Catalog #49-426.) He noted: “You can place them at key entryways to your retreat. They weigh less than a pound each, can fit in your hand,.run off a 9 volt battery, and emit a very loud alarm sound.”

SurvivalBlog reader “Bonehead” recommended this site in Australia for the off-road vehicle construction plans. Bonehead notes: “I saw these guys buggies in some of the most wretched places, merrily buzzing along, whilst large, heavier (read: uses much more fuel) rigs were busy getting themselves completely stuck. BTW, I’m building a Bandit–well, my version of it; that’s the great thing about DIY, you do it your way!”
