XXI century sundial with LASER – Arduino sketch included too… Alessandro writes-

This is a simple project of a sundial wherein the pinion is replaced by a line LASER I took from a LASER level. The LASER is mounted on a RC servo which in turn is driven by a micro controller. The micro controller keeps the time and turns the RC servo accordingly. Very basic in design it does exactly what I wanted and has as few parts as I could. The micro controller is an Atmel Attiny24 with crystal for better accuracy. The internal RC oscillator could be calibrated but in the end the precision can be achieved from a crystal quartz only.

    This is great. But what does it mean? Laser clock available from adafruit soon or just a repost from the make blog?

  2. Presidentpicker – we didn’t see this on MAKE, we posted it because it was a cool project. perhaps someone will make a kit, or perhaps someone will get inspired and make this project.
