I opened an old dvd burner to measure the current needed by the laser diode.

Never, really NEVER look into the laser beam!

It’s the same laser as in the first video,I just made myself an aluminum casing for it so it actually looks like a laser pointer.
around 75-100 mW I guess, 650 nm wavelength
Enjoy!

This floppy disk burn through is another example of what a 140mW red (8X DVD burner) laser diode can do focused to a few mils at a close range. Measured for this test at 84mW @ 650nm. WEAR YOUR EYE PROTECTION!!! These things can blind you “BEFORE” you can blink at this power! or at least make you sorry you saw it.
