Laser wood burning pen

Featured

Step 3: Final step

Now thread the fiber with the tip through the pencil. to finish the project put a small drop on the tip and glue it to its case. assemble the pencil and you are ready to run the diode !

Now you can burn everything :) Don't try it on your skin the laser will burn it immediately !

"NEVER LOOK DIRECTLY AT THE LASER BEAM AND PROTECT YOUR EYES WITH PROPER LASER GLASSES ! LOOKING AT THE BEAM WILL BLIND YOU INSTANTLY !!! '

The diode emits 830nm +/- 15nm laser radiation so you should use glasses that filter 750nm to 900nm radiation for your protection .

Does this thing really work? I don't see any photos of burn lines on wood! A 15 watt soldering iron will burn wood if you hold it there for 10 seconds. I seriously doubt a 1 Watt laser diode will burn anything other than your wallet. Prove me wrong please!

it does. there's a huge difference between 15 watts of electrical current converted to heat and passed through a soldering iron than a 1 watt laser. 150 miliwatts will pop a balloon.

To OP, is there a way I can take that up higher than 1W?
Why dont you all admire the science and not fight about it. its not just a laser, its an IR Laser...i am no laser scientist...i am a rocket scientist. i have no clue what all this stuff is...its all hebrew to me. just look at how cool it is, and try making it yourself or something. I think this is pretty cool, and if i had the money, i would try making it too...quit fighting.
dgw, 1 watt laser radiation is greater than 400 watt lightbulb lupins.
