Amazing RGB POV clock


We’re no strangers to POV time pieces around here, but something about them never gets old. Whether they use a ring of LEDs to draw clock hands, or an intricately cut HDD platter to replicate LCD segments, we love seeing them. [David] sent in this hard drive POV clock built by a fellow named [Kly], and it’s just beautiful.

[Kly’s] “Propeller” POV clock is named as such due to the design of the circuit board. The board is mounted on the HDD spindle, rotating much like an airplane’s propeller. The construction details are sparse, but from what we can find, it is based around a PIC32MX microcontroller, which is used to control the 66 SMD RGB LEDs mounted on the circuit board.

As you can see in the video below, the tightly packed LEDs result in some pretty amazing visuals.

Aside from watching the video below, be sure to swing by his Youtube channel for a handful of videos showing RGB POV clock in action.

    That is stunning

  4. Bob says:

    What’s powering the board? Is there a battery on it, or does he use brushes on the motor, or induction?

    Wow, really nice build. The animated cube feels like 3D :)

    What is the name of the soundtrack?

  7. DF417 says:

    If you tilt the board a bit, you could have a functioning fan!

  8. KnightFire says:

    Zowies! I’m totally impressed!

  9. Daniel says:

    Any chance you have the plans for this? I am a clock fanatic and would LOVE to build one of these.

  10. Daniel says:

    Oh, wait, I see his link now on his YouTube channel. I’ll check it out there and see what I can learn.

    Absolutely gorgeous.

    Impressive. Real treat for the eyes, but that music..oh for the love of all that’s good and holy, WHY?

  15. tim says:

    really cool clock, looks like it makes good use of those pic32 mips

    I wonder if it would be possible to integrate one of these in a motor and power it off of the back emf from the motors coils.

    i’m speechless

  17. Michael says:

    This is GREAT!!! Now all thats left to to is get it some wireless so you could use it as an output. Social networking, weather, traffic, news, rss, etc. etc.

    That is simply incredible! I’m floored!
