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 Sparkling Animated Christmas LED Snowflake Window Decoration

Can you hear the music, “Jingle bells, jingle bells, jingle all the way.” Christmas is getting closer and closer, have you made all the preparation for it yet? Honestly, the economy crisis has a big impact into our daily life, where we must try to save as much as we can. The truth is life goes on, and you still have to celebrate the Christmas whatever what happened to the world, right? If you can’t afford to buy the costly LED lights decoration, then you should consider building it yourself! Well, this is a very fun and valuable experience, where you can spend your quality time with your loved ones yet save some extra money by DIY the animated Christmas LED snowflake window decoration. This whole project is fully controlled by the PIC18F1330 microcontroller (ic4) using it’s internal oscillator. It multiplexes the 8×8 LED array by sequentially turning on one column at a time, and then sending 8 bits of data to the 8LEDs in that column before moving on to the next. Eight outputs of the 4028 BCD to… Continue reading
