Wow! Discover Elektor's Ulti(mate) Prop(eller) Clock with POV Clock Face

Electronics is at its finest when it combines physics, mechanics, and software with imagination, ingenuity, aesthetics, and precision. This is especially true of the Elektor UltiProp Clock from our December 2013 and January/February 2014 magazine editions. The UltiProp was not only designed to display time and date, but also to elicit exclamations of awe and admiration!

 

Our UltiProp propeller clock has two ATmega328 microcontrollers; one in the fixed base and the other on a two-blade propeller. The latter controls 2 x 25 dual color LEDs and displays a clock face, thanks to persistence of vision (POV) and a 3,200-point circular image. The image is stable and persistent because on the one hand, the two sheets alternately produce the same fragment and on the other hand, the microcontroller adjusts the image of the propeller speed. The 25 LEDs per propeller blade make it possible to view three 8-pixel high rows. The last is the seconds display on the outer edge of the circle.

 

 

All user settings are made with a single rotary encoder with a push button on the base unit: standby time and date setting, brightness and speed for day and night time, and language and display mode.

 

This cool propeller clock is available in week 15 (April 7-13) and can be pre-ordered now with a 30% discount. The clock is available as a completely assembled and tested circuit board through the Elektor PCB Service operated by EuroCircuits.
