Picture of PVC Camera and Light Mount
I've been wanting to do time-lapses of my art work for a long time, but never had the capacity to record any art I was doing non-digitally.  When I bought a webcam I thought I'd found the answer but I realized I never had the right angle.  
Because we're engineers and solving problems is what we do, my friend Silas Hughes and I designed and built a super simple mount for both my webcam and overhead light.

For this build I used 4' of 1/2" PVC, an L joint, a 4-way joint, a handfull of zip ties,  and a borrowed PVC cutter.

This build took me ~ 20 minutes and only cost about $6.  Super easy, right?

Step 1: Measure Twice...

The idea behind this design is that friction is your only fastener.  I live in a dorm room, so nails, bolts, screws, even tape can be a really bad idea.  What holds the PVC protrusion perpendicular to the wall in our design is a vertical portion of PVC which is sandwiched between the ceiling and shelf. This portion of PVC needs to be juuuust right.  Too long and it won't fit.  Too short and the whole contraption will fall over, useless and under-constrained.  

Step 2: Rotate and Tighten

There are a million and a half ways to cut PVC, many more dangerous than others.  The least dangerous and most practical way is with a PVC cutter.  It's a handy little device that looks like the bastard child of a c-clamp and a can opener.  You clamp it on where you want your PVC cut, tighten it down, rotate, tighten, rotate, tighten, and repeat until the PVC separates.  This makes for a nice clean cut with no nasty dust or sharp edges.  

Step 3: A Very Ugly Pipe

Join the L joint with your short piece of pipe by shear force of will.  You should have something that looks like a pipe most unworthy of Hobbit's Leaf.

nice job but a pipe cutter is not the right tool to cut pvc but looks good
