Firing Bullets Through Propellers

Early airborne combat was more like a drive-by shooting as pilot used handheld firearms to fire upon other aircraft. Whomever could boost firepower and accuracy would have the upper hand and so machine guns were added to planes. But it certainly wasn’t as simple as just bolting one to the chassis.

This was during World War I which spanned 1914 to 1918 and the controllable airplane had been invented a mere eleven years before. Most airplanes still used wooden frames, fabric-covered wings, and external cable bracing. The engineers became pretty inventive, even finding ways to fire bullets through the path of the wooden propeller blades while somehow not tearing them to splinters.

Max/MSP accelerometer beat control

[Ryan] let us know about his Max/MSP Controller. Inside the device is an ADXL 335 accelerometer and 6 push buttons wired to an Arduino. The input data is sent to Max MSP, a sequencer controlling 5 audio tracks, correlating to 5 of the buttons. The 6th button controls delay. What we really liked was how the accelerometer modified the speed of the beat in the X-axis, and the delay intensity with the Y-axis. Whats next? We think gesture recognition might be something fun to try, but [Ryan] is unsure. We’ll keep you up to date.
