Some people seem to be born with all this handy knowledge to make their projects much easier and quicker. Some of our collaborators have the best hacks you can imagine, and here we bring you some of them. I use lots of handyman work in my profession as an engineer and designer of computer circuits and robots. One of my robots was made from wood, metal, electronics, motors, sensors and some computer parts. I love dong it. I really like the idea, someone's watching you, while you open your car with a valid screwdriver handled key. I guess police won't like it as much. On the thumbnail that latch clip below the rear car bumper is designed to tie-down the trunk lid if something is too large to close completely. Also street racers tie a little "beanie-baby" stuffed toy from these tie-down bumper loops as an advertisement that they will accept a race challenge.
