Like most geek-filled offices, at my workplace we have several Nerf guns and similar toy weapons floating about. Not impressed with the performance of my colleague Lester’s Nerf Maverick, a mainstay of Nerf’s suction-cup-dart-firing “N-Strike” series, I decided to build a better Nerf gun myself.

In early 2011 my robot club, the Dallas Personal Robotics Group, was looking for a way to help our beginning members build up their skills. To this end, we produced a series of lessons covering 5 topics needed to make a simple, programmable robot: making PCBs with the toner transfer method, programming ATtiny microprocessors, laying […]

Using some of my […]
Sometimes nothing is as important as perspective. My goal in photography is often to find a view no one else has found, to be able to see things from unusual and insightful vantage points.
