  • can you get in to xbox 360 kinect ???

    i know you are in to crafty stuff! so surprise me!!!!

    google Xbox 360 Kinect Night Vision Test

  • @xtreme404 I've been turned off by the lag in the Kinect.

  • I've always wondered how that worked. I have a YAG laser marker for writing on wafers. A black light and phosphorescent plate are used to find the IR beam. Always wondered what was going on since it seem counterintuitive. Excellent videos.

  • @ngneer999 Jealous of your YAG laser.

  • Can you not get CdS LDRs in america? They're easily available in the UK for about 30p (50 cents)

  • @alecjw11 They're getting harder to find. Stupid laws about Cd. Politicians don't have a clue what they're voting on half the time.

  • they don't like copper and galena either - makes for a good whisker diode though

  • You are so cool I wish you were my friend so I could learn more from you! dr.b

  • @jeriellsworth I think you're being too nice to politicians suggesting they actually have a clue 50% of the time... Banning incandescent lamps was one example. The same government banning them for being so inefficient are actively uprating the streetlights to use more power/cause more light pollution

  • I have two suggestions. KipKay how to see in the dark. Could you show exactly how to do that? I have a stripped out LCD and I wish to make a drawing tracing table from the lamps. Do you have any ideas on how to do these projects? Thanks for the videos.

  • 2:41 you mention "...our burycrat is thinkig it poison us". I Norway electronics sell out, have to disposel electronic's for the buyers, or else they are prehidbbed to sell them. bye law.

  • @jeriellsworth

    :( i know what you mean! :) "xbox slow!!!" can you hack it???

    Kinect Night Vision video show that dots on camera right??? i know that is not laser!!

    take the same idea and apply that a laser system and could be used to remove snow as they fall???

    stupid idea!!! i know fun/ dangerous project!!! can build a rig???

    sorry for my lame English!
