Video graffiti
« on: November 28, 2012, 03:17:26 am »
Since I can project without having to "plug in," I can now spew video graffiti anywhere!

Basically I connected a small LED projector to a gel battery.  I then packed them and a DC adaptor into a discarded Tucson Public Schools box, with an iPhone cord.

12 Volt, 9 Amp gel battery:

90 Watt, universal car DC adaptor -- Input 11-15V, 12A; Output 15-24V, 6A(max):

LG HS201 LED projector, 19V, 4.74A:

HDMI and other input connections:

This projector lasts over an hour on one charge.  It is an LED projector, so there are no bulbs to burn out and change.  Nevertheless, it puts out 200 ANSI-Lumens, which is fairly bright.  While this model is discontinued, LG does sell other projectors.

Perhaps I can power this projector by bicycle, instead of with batteries.  In San Francisco there are concerts now powered by the audience pedaling.

Of course, the Graffiti Research Lab has been laser tagging buildings for years.  But how about recent video graffiti variations, like water light graffiti, and SweatShoppe in Europe.
