Default *SOLD* High Powered Red, Dorcy Jr host

This is a Dorcy Jr. Build by Jake21. * Jake estimates it at 230-250mW. *I don't have a meter to test this but it burns black plastic, fabric, etc. at 3 feet (where it is focused). *It will of course light blackened matches and pop dark balloons. *It will light a regular red match in ~20 seconds.

I have had the laser for about 2 weeks. *The open-can diode has only about 5-6 minutes total of use. *I once ran it for a little over 1 minute continuously and the end of the heatsink warmed just a little bit, hardly noticeable. *I'd bet it will run 5 minutes or more without much heat, but I have no reason to try that...

I am selling this to finance other laser projects, and because I have too much $$$ in lasers already! *It is a really solid build IMO. *Asking SOLD, which includes shipping in the continental US. *I will ship elsewhere too at actual shipping cost minus $5. *See the last post below for some good reasons to choose this over cheap imports!

I am not the best at photography but here are my attempts:

Pic #4. I tried to get the smoke to show up in the photo, but I was unsuccessful. Rest assured that this black plastic tape measure began suffering instantly

Does Jake's heat sink/module make this a "fixed-focus" laser?

Yes it does, thanks Dave. *It is permanently focused at about 3 feet, and at that distance the spot is 1mm or less. *Across my yard at night (100 feet or so) the spot is a few inches in diameter.

The ~20 second time was for a "regular" red match. A blackened or black match would light significantly faster than a red one.

Peace,

Thanks for the offer Jake21! *

@ L@z3r: *yes, it lights anything black instantly, including a sharpied match. *If I understand correctly, lighting a red match is a different story entirely since a red match absorbs less energy overall than a black match. *I think lighting a red match in 20 seconds is pre tty impressive for this laser, but maybe I should have left this fact out...it seems confusing.

Hi Hansheng - I am happy to ship to singapore, you would pay $5 less than the actual shipping cost. I don't know anything about singapore customs or importing, but I could mark it however you want, call it a flashlight, or whatever helps get it to you. Send me a PM...

Jack

I think so too...I was surprised it worked! My 5 year old loves it (of course he always has goggles on!)

Bump with a price drop, now $70 shipped CONUS. I will also throw in 2 Panasonic CR123 batteries. This is a great burner!
