Photographer Greg McCown had a lifelong dream to capture a rainbow and a lightning in a single image. This may seem crazy but if there is one place in the US where the weather is crazy enough to pull this off, it has to be Arizona.

Two days ago, his dream came true. Greg was driving on the I-10 and was hit by a wet microburst which brought the traffic close to a standstill and visibility down to 20 feet. Seeing the rainbow Greg decided to chase it and try to get his prize shot. Luckily he did.

After successfully funding the Vela One – an uber-high-speed strobe the obvious question was now that you have a trigger that can freezer a bullet in mid air, how do you trigger it to catch the action. This is why I am not surprised that Vela Labs now announces the Vela Pop, a companion sound trigger for the LED strobe.

There are other solutions out there if you want a sound trigger: Camera Axe is one of them, MIOPS is another and  TriggerTrap is a phone based one, and while that are all very good at what they do, Vela Pop does bring some news into this market:

How To Make A Laser Camera Trigger For Under $2

OLYMPUS DIGITAL CAMERA

Shooting a bullet in mid air requires a special type of detector to ‘catch’ the bullet in mid air. Usually, a special sensor called a ‘gate sensor’ is used. The trick is a gate sensor is that it can calculate the speed of the bullet and ‘nail’ the shot at the right time. Those are not trivial to build.

This is why I was pleasantly surprised when I got this tutorial from Matt Kane who managed to build a bullet catching circuit for under $2.

Matt used a phototransistor along with a red laser to build cheapass bullet detector with the entire cost of the build being under $2: [Read more…]
