We have a lot of home made equipment, my favourite at the moment is our five foot linear tracking system, this cost £25 ( about $55) to make, and works amazingly well. Not only can it fit in a back pack but it can take a huge weight, in fact the heavier the better! The only precision parts are the bearings ( about $3 each ) they are from skate board wheels. the 'dolly' part itself fits into a small rucksack and is simply bits of aluminium cut to size, all off cuts from a metal shop. All you need is a drill a saw and a tap and die set, and if you're really posh some paint. The things it sits on are door handles and the big screw knobs are off a roof rack. One last point is the tracks have Teflon tape on them so the dolly runs silently. Though I'm sure any smooth tape would have worked. Here are some pictures of it.
