This wall mounted piece is my first solar powered artwork. Part of
the inspiration was the annoying power cord that is a visual distraction
in a gallery setting. I also felt it was time to make a solar piece
- since I'm such a solar guy!
This piece requires strong light to operate and the displays will go blank
with insufficient light. It will operate for up to an hour after the
light level drops, since each display module has a super capacitor for
power storage. Each module has it's own separate solar panel and
operates independently.
The
circuitry changes a randomly selected digit to a new random number every
second or so. |

A footnote: I
designed the circuit boards for this piece in July 2004. When I
assembled the circuit and began programming the microcontroller, the
displays kept showing gibberish rather then the intended numbers. So
I put the piece aside, and it took 17 months for me to get back to it.
What I found was that I had mis-wired quite a few connections on the
circuit board. It's the price I pay sometimes for being a dyslexic
artist! It took me a few hours to fix the wiring - the wire jumpers
are hidden on the back of the boards. You can see the title, and my
name and the original date are all etched into the boards along the top
and bottom edges. |
