To spice up his daughter’s birthday party PeckLauros fashioned a tricky contraption that seems to come from an old movie house. It’s actually a replica of a camera that sits in one of the corners of their party place – but this one is not an ordinary camera replica – this one actually roles the reel when someone comes into its range of vision. To make it clear it only roles the reel not really recording things – but kids love it.
This neatly constructed piece of work was made using PVC tubes, elbows, a servo moto, a couple of DC motors and of course who would miss out – the microcontroller. PeckLauros used a basic stamp in conjunction with a servo motor and an ultrasonic range finder. The ultrasonic range finder emits ultrasonic waves when an object comes near enough the echoed waves will be detected at the receiver which will trigger the basic stamp to send pulses to the servo motor for the slate and also triggers the DC motors that will turn the reel. Cool huh?
