POV clock

TC

Hello all,

For years I have wanted to build a POV clock. But I was always afraid I would start on it, and find out i do not have the knowledge or experience to program it. I understand the theory behind it. And I can visualize what I would have to do with the hardware. But the programing side, I have no idea what I am doing.

Could anyone offer advice that could help me?

thanks
TC

I have seen several POV clock projects on the forum so you could use one of those as a reference. The mechanical portion is more difficult than the electronics and programming IMHO. Circuitry and program/timing requirement is similar to multiplexing a display or generating a video image.

I played around with a ceiling fan and a QuickStart for a while.
I got is sorta working. But the lack of an indexing mechanism was a stopper.
(Some way to tell where the start point is located in the revolution)
Probably could have worked out something, but there were other projects to play with and I moved on.

There was a very good project at Defcon 20 a few years back.
It ran on the Defcon Badge boards.
Worth taking a look at for a startring point... http://pastebin.com/Ubv7qRii

The programing portion is harder for me. I have not done much work with multiplexing, and never done anything with video. Guess this would be a good way to learn.

OK, that would be a cool idea. Thank you for the link.

Wonderful, thank you. That does help me figure out where I should start.
