Light Box

Monday, October 26th, 2009

A friend and I spent some time a few months ago collaborating on an art piece.  His Light Boxes usually consist of some translucent material, film, printed transparency, large prints, envirotex casts etc, that are mounted in or on a box, with a light behind.  Sometimes the light moves, sometimes the piece moves, sometimes both are static.  We decided to see if we could combine our skills and come up with something a little more dynamic, possibly even something that people viewing the piece could interact with.

New HeatSink

Monday, October 26th, 2009

This Project Actually Completed January 2009

This is a revision of the aluminum heat sink we have been using for the the 3 watt tricolor LED control boards.  These will serve as generic tricolor led drop in modules for future art pieces.   The control board has 3 FET control channels 1 for each color and a microcontroller, for the brains.  On the top sits the LED nestled in its heat sink to keep it cool.  The whole assembly in its present incarnation looks like this.

Sun Light

Monday, October 26th, 2009

This project was actually completed in March 2009, WOW!!!

Our house was built in the 30’s and some some of the fixtures are still from that time period.  One of the rooms in our house had and old bare bulb in the ceiling, it used to be switched by a pull chain but that had long since broken.  The only way to turn the light on was to reach up and screw the bulb in, and reverse the process to turn it off.  Not so fun!

After removing the old fixture, I realized the ceiling tiles around opening were very tattered, cracking and peeling back.  The base of my new light was not large enough to cover the area, and the ceiling tiles were way to old to be replaced.  Thinking about some way to cover this area before I put up the light, my brain saw the opportunity to use the CNC machine.  Aha!! I had figured out a way to spend the Saturday playing with the machine in the guise of working on the house, brilliant. 😉
