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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

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