Bounce flash in multiple mediums

[Nigel's] been trying out a series of designs and materials to make his own bounce flash. He set out on this mission because most of the images he used flash on ended up washed out with dark shadows. The flash add-on seen above seeks to curb the harshness of the direct light but shielding the subject.

What you see above is just a couple of pieces of paper. [Nigel] put together a template so that you can cut your own. Although the design is his favorite, he also put together a second generation that is built from hobby plastic with a piece of aluminum tape as the reflecting surface. The main link at the beginning of this feature leads to that version, but after the break we’ve included direct links to each article he published during his experimentation.

The Blind Juggler

The Blind Juggler is a robot that juggles or bounces balls in a controlled manner without any sensory input. It is basically just a linear actuator with a paddle on the end to smack the ball back into the air as it returns to the ground. The crazy thing is, it is doing this based purely on pre programmed math. There are no sensors telling it to make any adjustments. While we could envision this functioning, we would never have expected it to be as stable as it is. You can see in the video above that they can actually move the entire robot around while maintaining the bounce. Also check out the pendulum version, instead of just actuating vertically, it is mounted as a pendulum allowing the ball to travel back and forth in an arc.
