Lots of spinning POV goodness

[Retrobrad's] spinning POV display has long been our favorite. When it popped up on our radar again this morning we were surprise to see we never ran a feature on it! But now there’s so much more to share. Hit the projects icon at the top of his page and you’ll not only get the 8×85 RGB display’s build instructions, but he’s also built a 32×64 pixel spinning display.

Even if you’re not going to make one of these, he explains some pixel-graphics techniques that are useful in other instances. Check out his video on using spreadsheets for creating the hex arrays necessary for each frame the 8×85 display. It’s embedded after the break along with demos of the two displays.

    Nice, probably some of the best graphics Ive seen done on a POV. This has serious consumer product potential. Parents will gladly buy something like this to keep babies entertained with their favorite cartoon characters.

    These POVs are making people fat and lazy; when we were kids, we had to spin ourselves around.

    it would be awesome if someone could make a driver and program a propeller or something to use one of those as a secondary display for a computer via serial or usb.

    @roboman2444
    That’s exactly what I was thinking about doing when I saw this. It reminds of the program to use a psp as a second display.

    these POV’s keep getting bigger and bigger, anymore larger I’d be scare shitless something giving out at high RPM’s. Yea I remember having to spin myself LOL.

    Hi everyone and thanks for the comments.

    I can’t actually claim the last video though, basically because I didn’t make it!

    I have made a POV display that does everything that the old one does but now only uses one chip (instead of seven)

    I will upload a video to youtube in the near future.

    This makes me want to do POV. Although, I’d code a bitmap parser instead of using excel/hxd; but that’s mainly because I’m not really a fan of repetition. I’d just code a bitmap parser, instead.

    that last video creeps me out for some reason. there’s just something unsettling about those ancient, badly-drawn pixelated cartoon characters flickering in total silence.

    Next 1024 LED POV, I dare you!

  11. ferdi says:

    1024 led,s its posebal use small led but a hell bit off work

  12. Gdogg says:

    Anyone else think it’s hilarious/ridiculous that he has a ‘god page’ on his electronics website?

  13. retrobrad says:

    @Gdogg why do you think it’s rediculous?

  14. PR0CR4571N4T0R says:

    I thought the god page was quite fitting, given the subject matter and overall design of the site.

    Im very eager to see some updates on the 32×64 POV, as ive wanted to build one for about two years now

    Maybe think about selling closed-source kits, if youre not ready to share the complete project.

    Id certainly be interested in making a money order/deposit.

  15. Gdogg says:

    Because there’s no real reason to add ‘controversial’ stuff to a site that has nothing to do with the website. It’s like HaD posting about the book of mormon.

    Obviously you’re free to do it, it just seems super lame/creepy to include it.

  16. bancroft says:

    i wouldn’t call it controversial. the guy has convictions, it’s his site, so let him put up whatever he wants.

    if he like cats, then would you object to him having a ‘cats page’? or would that make him creepy?

  17. retrobrad says:

    God has everything to do with electronics since he is the chief designer and creator of everything.

    I am thankful that Hackaday thought my design was pretty cool and decided to do a write up about it. I think God’s design is pretty cool and decided to do a write up on my site.

  18. Gdogg says:

    @bancroft Yes

  19. Tim says:

    Good on you Brad.

    Gdogg, why do you think this is a controversial issue?

    if people want to read about God, they can read it!
    if people don’t want to read about God, they don’t have to read it!

    “We are in the position of a little child entering a huge library filled with books in many languages. The child knows someone must have written those books. It does not know how. It does not understand the languages in which they are written. The child dimly suspects a mysterious order in the arrangements of the books, but doesn’t know what it is. That, it seems to me, is the attitude of even the most intelligent human being toward God” – Albert Einstein
