Title: Dangers in taking apart a dvd player.
Post by: Hawaii00000 on February 24, 2009, 10:31:41 PM: I want to take apart a dvd player to do something like a this http://www.instructables.com/id/Awsome-50-diy-projector-well-for-me/ . Is there anything, besides capacitors, that I have watch out for so I don't kill myself.

(unplugging it is kind of a no-brainer)

Post by: MaltiK on February 25, 2009, 02:02:15 PM: DVD players use a laser diode... and these are very dangerous because they operate on the 600nm wavelength, which is invisible to us, so you could have it turned on and it be shining directly into your eye, and you wouldnt know it until you become blind

careful :)

i thought we were talking about dvd readers?

and no... vcrs are similar to an analogue signal, using sensors to read the em tape, and dvds are digital using diodes to read the em...
