[Wilywyrm] needed to find up with a final job for art class that commented on a social issue. Healthcare, schmealthcare, he said, as well as busted out this motion picture poster about the NSA spying scandal instead.
The circuit utilizes three extended-duty astable 555 timers to manage the brightness of the 5050 RGB common-anode LED strips that run up the sides of the 24″ x 12″ x 1/4″ acrylic panels. Each of the three panels was laser-engraved at 600 DPI on an Epilog laser engraver as well as features a different element of the poster. There’s one for Snowden, one for Daniel Craig, as well as one for the text.
[Wilywyrm] connected the color channels together in the very first panel to output white light. He utilized red for the second panel as well as blue for the third. A total listing of parts with develop notes is offered on his Google Drive. [Wilywyrm]’s notes include enhancement ideas, like making all the RGB strips color-adjustable with a lot more 555s or a microcontroller as well as timers.
Perhaps [Wilywyrm] might get into the remove whiteboard service after college.
