Optical recognition LED control


I probably shouldn’t find this as worthy as I do. It’s the optical recognition equivalent of wiring up a LED to a switch,, but it just appeals to me. [Ashish], one of our favorite optical recognition hackers of late, sent along this product of his boredom. If only he’d give us some source and a wiring diagram…

    THAT SUX i did this sort of of thing like 2 years ago once i was getting in to parallel port control with robotic vision

  2. Jakeh says:

    Hooray for techno-magic! Please release the code, I really want to play with this…

    Come on mccown, lighten up.

  3. kcbanner says:

    mccown what your saying is that what you did sucked? I dont really follow you.

  4. cfinger says:

    sweet, Ashish is awesome. Hopefully his RC car controller gets listed when its done too.

  5. Zencyde says:

    This is an interesting hack. Sure, it’s not new, but it’s a new (it might have been done before, but I haven’t seen it) mix of old hacks. I like it. :D Thumbs up for the work and I’d like to see what people do with this in the future.

    A friend of mine did an optical shape scanner uh, 6-7 years ago. He used grid of optodetectors with some LED ilumination. Was pretty kewl..

    Otherwise: I really hate shaking-camera-on-15cm-objects takes.

    @1: Okay, so what if you did it before, as far as I can see this site exists to highlight people that have done something and taken the time to make the information available (okay so this one could do with more detail), did you post your info somewhere when you were finished so beginners like me could get inspiration and information from it?
    I love this site, it’s the smaller hacks that help me to understand what will be possible when I’ve finished learning my uC programming and give me an idea of how much can be accomplished within reason.

  8. s1eve says:

    OMG! This hack has neither proper description nor is it new, useful or demanding in terms of programming skills. Therefore it receives the *bullshit price 1st class*

  9. Tim says:

    What is it about youtube videos and the disturbing lack of common sense to sit the camera in one spot and not shake it around like a madman?

  10. MRE says:

    My technically inept roommate felt the video required some sort of stability type device. Perhaps said hacker could have ‘hacked’ a tripod first.
    I took issue with mixing country music with hacker video.
    Otherwise, nice programming.

  11. PKM says:

    I agree about the shaky one-handed camera but if you are trying to show multiple objects in close-up and don’t have a cameraman it’s difficult. The earlier posts on his blog are mostly in a similar vein, combining a couple of simple hacks to make a neat device. the laser gesture-control coupled to a serial port relay for controlling electrical items is a neat hack that I’d like to try.

  12. Bill says:

    No matter what hobby/special interest website I go to there is always an unfortunate group of people who seem to be compelled to criticize someone else. Some of the above posts reflect highly evolved egos. I agree with the comment made by Phil. If you had done something like this in the past but did not take the time to create a video record of the event, your experience is irrelevant to us. The community would be better served if, instead of announcing your superiority to the world, you recreated your work and supplied us with a video record. In other words, put up or shut up!

    the first LED is overloading,he should have put a 330 ohm resistor in front of it to protect it other wise it may explode

  14. s1eve says:

    well the problem with people dedicated to criticizing is, that here is a lack of such people. it’s plainly stupid just to say “ah, nice hack, cool *wankwank*”. That’s boring. to bring up a discussion it needs pros and cons and some people here feel dedicated to providing cons. what else reason serves this comments page if not to discuss?

    I’m pretty much a beginner to this whole electronics business, but what would some conventional applications be with this?

  17. Chad Kos says:

    I have seen applications similar to this in the past that are being used for office personal recognition systems. In one example the LED controller detects where the subject is located and which way he or she is facing. I believe the system I am referring to was designed by Lunar Accents Design ( http://www.LunarAccents.com ). I have also seen other LED control systems in the airport which detect the movement of passengers going through the metal detectors.

    Hey Mr. comments 17! I already check it out from
    http://www.lunaraccents.com/technology-programmable-LED-controller.html

    and found something about Led controller that can me LED chasing on the board and among those boards. It is cool idea but they price is not cool at all!!
