Just did some testing this weekend on my new printer that I put together. I wanted to quickly throw something together to see what SLA is all about and also to see if my projector works without any modification. Turns out it does

How I print:
I don't have a Z axis Limits so I just set my build plate slightly above the resin surface with some resin poking out of my perf board holes. I then start my print.
8 Second Exposures on first 3 layers
2.5 Second Exposures on all other layers.
Printing at 0.05mm/Layer
Parts:
Arduino Uno $5 (Ebay) - Running HTL's Code. Super simple code. I made some slight modifications to it.
A4988 Stepper Driver $2(Ebay) - Soldered directly to the pins and shrunk tubed the whole thing. Added connectors so I can remove it easily. Running at 1/16 Micro Stepping
Glass Vat $2 (Dollerama) - Nice thick glass and its square. Perfect size for what I wanted to acomplish
DVD Drive Laser Rail $1 (Ebay) - Got 10 Broken DVD drives for $10 on ebay. Took it apart for just the rail.
12AWG wire and Perf Board which I had used for build plate.
Below are some pictures:
