  • I've started using all the modules and extra diodes I bought, to make a laser show box. I have plenty of little dc motors around. Already figured out how to make some huge freaking beams when I was playing with Nichia 08's.
    I've now added a 515nm-520nm fat beam to my collection. SO SWEET!

    Oh and if you get the right listing, the fat beam comes with a ttl down board, so always on, and with a 2a wall wart, and the driver board has an extra pin out for a second module to daisy chain.

    An if you are gonna do fat beams, you have to, have to, have to, oh gawds you havez tooo!!!!, get some fog machines. !!!!!!!!!!!!!! lol

    best I can do is on the profile. Idk how to get pics to upload here.
    I am now the proud owner of a 200mw-250mw( 250mw driver, cranked all the way up, so maybe a little more or less, don't have an lpm yet) 635nm. It's like a baby little tiny burner.
    I have completed 3 pen builds, 405nm 150mw, 445-450nm 4000mw, and 532nm 100mw. While burning things at 10 feet while lying in bed is rather cool, I much prefer the 532nm pen. Not only is the 532nm the brightest of the three, it's just really a sweet color.

    make an exotic but cheap wavelength pointer next like 545nm or 555nm

    I want to do up a 495nm and a 488nm pen next. Seems those two lengths are hard to find for a reasonable price in a pen form. I ordered up some 488nm fat beam modules. Should be in any day now. Next fat beams will be 495nm.

    Where did u get those fat beam modules?
    Upon completing how to build a cnc laser module ( by back tracing circuitry elements and looking up what they were) and activate the ttl/pwm signal to set the board without an engraver running, I moved on to a cooling system. I built the cooling system of Tec chips and controller boards ( like many circuits before). Keeping the laser at a steady 65 degrees F and the steppers at a nice balmy 80f.

    This will allow me to monitor the board for any weird stuff, maybe enabling me to replace it before blowing a $200 plus diode ( worth a shot). I turned a $400 machine into a $2400 machine ( the driver was $500 alone).

    Hopefully it is capable of doing what I designed it for, continuous running. So far testing has been very positive, over 100 hours of running and no noticeable difference in power or depth of engraving into glass.

    I could have done this all way, way, way, cheaper ( $200 if this was gonna be a hobby level). This is for a tiny business, so I need reliability and longevity. I now have multiple modules build for different substrates, with corresponding best wavelength laser diode. Now I am able to keep the wavelength stable as well. No more drifting as it heats up.
