POV propeller clock to spin your world

POV – when I first saw this I thought it is a new name for a robot of some kind but when I searched about it – it turned out to be something more interesting. POV means (according to my google search) Persistence Of Vision, this is a condition when something moves faster than what our eyes can decipher – this makes a dot look like a line. It’s the same principle used in a CRT television using super fast scans to make the picture that we see. There are a lot of POV projects out there but nothing could compete to the workmanship that Kizo put to this spinning light of wonders. It was made using an ATmega324P and 3000 lines of code. The LED array is composed of 40 cyan LEDs driven by a TLC5916 constant current driver. To sense the current position of the propeller Hall Effect sensors are used. And the MOST! And I say the MOST! Outstanding detail about this POV project is that power is wirelessly transferred to the propeller blade by using inductance.… Continue reading

The Astonishing POV Propeller Clock

Could you guess which the most common household gadget is? Well, believe it or not, according to the survey, clock is the most familiar gadget in every household (It wasn’t a surprise, isn’t it?) However, up to 90 percent of clocks are usually designed in a very boring style. Well, if you’re getting bored with it, and you like something more spiffy here, maybe the POV propeller clock is going to light up your life! For this project, one of the biggest problems is to find a motor. First of all, the motor need to be very silent and has the ability to make more than 25 turns per second! In addition, the motor that being used must able to transfer the power from the clock circuit to the POV PCB continuously. Beside that, those components you’re needed for this project are: Ball bearing (It’s for holding the top end of the motor). A .047F capacitor (It keeps the PIC powered up and allows you to set the time). A miniature 3V lithium watch battery. A Zener (It regulates the… Continue reading
