RGB “Tilty cube”

[Ben's] introduction to microcontrollers was this fun little gift he calls the “tilty cube”. It is an acrylic box with 3 LEDs mounted inside that changes color based off of how you tilt it. Sounds like a fun toy, and a good project to learn with. [Ben] chose the PIC12F615 as the brains and laid it all out on a perfboard.  Since this was his first microcontroller experience he had to learn how to blink the LEDs, then figure out PWM etc. Though there is no video of the project in its finished state, since it was given away as a gift, we assume he figured it out pretty well.  He does state that the LEDs are dimmer than he had hoped and offers some thoughts on how he would do the entire project better next time.

    Totaly ready that as titty cube

  2. dmcbeing says:

    Much better than the typical led “Hello World”.
    @Some Perv:Same Here :D

    Third for misreading the title.

    My disappointment at the lack of a titty cube has led me to ponder my next project.

    Legend of Zelda, Red Green Blue Cube puzzles. That’s what this needs to be.

    Is there a video anywhere? I’m interested to see how smooth the color changes are and how complex the algo is. The way I would do it is use each axis of a 3-axis tilt sensor to adjust the R/G/B PWM values. So tilting along the X axis would change the R value, etc.

    i was thinking it was injected with silicon or something.

    Also misread the title. Can someone please make a titty cube?

    Compiz Desktop Cube + pr0n = titty cube. QED.

    damn… I wish I’d read it as titty cube. :( I am getting old.

  11. asheets says:

    This is right up their with Sean Connery’s “Penis Mightier”.

  12. I had this idea the other day… nice first project!

    Hey, I’m the guy who put this together. Sorry about calling it a Til(t)ty cube. The algorithm is just that, each axis controls a different color. The colors change rather smoothly, it’s a cool effect, but I never made a video before I gave it away, so you’d be hard pressed to find one.

    Heh. nice work. I hacked a low-fi version of this together a year or so ago with 3 mercury tilt switches, an RGB LED and a few resistors.
    Awesome first micro project.

    One thing I like about this site is how often a post will inspire others in the following days that are improved versions of the original post, or “this is how that should have been done”. Totally waiting for follow-ups here.

    Glad to see im not the only one who misread the title

  17. jim says:

    …where as a luddite like myself would use reed switches and a few resistors, and maybe a 555 timer for good measure.

  18. Marvin says:

    Hey! This would be an cool effect for LED juggling balls!

  19. ibanex says:

    I read tity cube :-)

    I keep looking for a Titty project on HAD, and this is the closest I’ve seen!
