yeah, it's cheaper to head to best buy and pick up a $10 tripod than to DIY one. That being said...:
A-3 4-ft 2x2's ends cut in opposing 60 degree angles (equilateral trapezoids)
B-make a equilateral triangle with 2" sides
C-put a 4"x4" chunk of thick plywood over that to stop the legs from riding up.
Drill a 9/16" hole through the center of the triangle and square.
Attach the Legs (A1-A3) short side down to the center piece (BC) with B towards the floor.
Link the three legs together with chain (rope is too stretchy) in middle of the legs if camera is too heavy for it.
put a 9/16-20 wingnut upside down onto a 9/16-20 bolt. Feed this through the hole from bottom to top of the BC unit, screw into camera until snug, then tighten wing nut to pull camera snug to the tripod.
Total cost: $20...I know, I've done it...The best buy thing worked better, but doesn't hold as much weight.
No, most cameras have a 1/4" 20 threads/inch threaded hole to which the tripod head will be screwed. In the price range your talking about, this is universal. Some very large and very expensive cameras have more industrial mounts. You can purchase virtually any tripod at a camera store, etc. Just beware that tripods have a weight limit. If you put too heavy a camera on a tripod, you might find yourself with a broken camera when the cheap, plastic quick-release breaks loose under the strain and your camera takes a nosedive on the concrete. You should be able to get a decent tripod that will hold up to 4 pounds for around $30.don't they make specific tripods that fit for a specific camera? or is that $10 tripod universal for all cameras.
