Good work my man, sick build! I really love what you did with the fan, and really glad you shared it here!

My pleasure! Congratulations on winning :)

I will be, 10% off all handhelds. PM me for discount code :)

This months winner is @Unown (WILD) ! Congrats! Contact me to get your new laser :)

I would prefer if you contacted me through private messages, I've gone ahead and sent you one, please check :)

Amazing collection! Glad to be part of it!

Last day to enter the draw! :)

Yup, will use entirely two different ones just to make sure to get consistent test data

Yes, you'll need to attach a keyboard Pressing 's' will save all data. It saves graph and waterfall data as PNG images, with date and time as part of the filename. Additionally it saves graph data as CSV that can then be opened in other programs such as OpenOffice on the Pi.

Yup, 0.1nm resolution, its impressively accurate

I don't unfortunately, I built it for myself Here is the github for the project I used: https://github.com/leswright1977/PySpectrometer It uses exactly the same parts, same specs everything. My unit uses 2x 18650s to run in an enclosure

I can build you a calibrated one for $400 USD + shipping

Hey Chris! Thanks for looking into my lasers. I work a one-man operation all by myself, and half of the week I take care of my 2 year old toddler, so the time I do have, I spend it building lasers or resting :) Feel free to send me a PM here just in case your email was sent to my spam folder

Yup, Nichi@ makes bad@ss diodes 7 amps like its nothing, and can still lase if the temps go back down Check my results for the other diodes, there are some surprises in there! https://laserpointerforums.com/threads/jlasers-blue-laser-diode-tests.111300/

Same as all others. I'm waiting to post NUBM47 data until I test all variants properly

Use a proper hot plate at 240C Your heat gun does not have enough power even at 400C

Around 50C on the body I haven't fully tested these yet as they aren't very popular anymore

Oh yes! Check out my tests thread: Blue Diodes: Green Diodes: NUBM0A NUGM02 NUBM0C NUGM03 NUBM0E NUGM04 NUBM0F NUGM05 NUBM0G NUGM06 NUBM05 GH05C01A9G NUBM06 GH05C01B9G NUBM07 NDG7575 NUBM08 NDG7475 NUBM4B NUBM42 NUBM44 NUBM46 NUBM47 NUBM49 NDB7875 NDB7A75 Look at the wavelength data as power...

Alien Laser confirmed with me it was the XJ-A141: "I can not upload images but yes that's the projector Casio XJ-A141 DLP Projector" I also extracted diodes from this projector as seen here: https://laserpointerforums.com/threads/the-laser-projectors-diode-list.110913/ I tested every single...

I believe it was the XJ-A141 which these cyan diodes came from Alien laser posted on May 16th: 4 days ago i received 1 = XJ-F210WN Brand new 0.0 hrs i was planing to extract diodes but i wife liked it so i stored it away. So i ordered 3 more brand new XJ-M146 + XJ-A141 + One more XJ-F210WN I...
