    Need a premade laser that can cut through tape at minimum

    Hello there Alaskan , I would recommend a prebuilt laser from sanwu or survival lasers but because this may be your first laser I strongly recommend you get a laser that's under 1w in the range of 200mw to 500mw because you have to start with something not very powerful for your first laser not...

    Hey you guys can I ask you something?

    Rich it's ok don't be sorry. I am located in Greece and I do not really need an other driver as I am not really concerned about size and testing it on a burned mitsu 150mw it performs well. https://ibb.co/kyxgvb3

    Hey you guys can I ask you something?

    Hey Rich the driver performs very well and I also don't have the 30+14 USD for shipping. It was my fault for burning the diode my driver outputs a constant voltage of 2-25v and a Constant current of 0-2Amps(measured with a very good multimeter. It was my fault bc I did not look at the...

    Help me choose the right Driver

    My mitsu 150mw red died today I thought that the operating voltage of red diodes was 5-6 rip but the driver is doing good and it's rock solid red=voltage and blue = amps https://ibb.co/4f1KzqG https://ibb.co/kyxgvb3

    Hey you guys can I ask you something?

    Hey you guys can I ask you something?

    Ik Rich but sadly I was under the impression that red diodes need 5+ volts so I fried my Mitsubishi 150mw one is it possible to bring it back by soldering the tiny broken wire?

    Help me choose the right Driver

    quick update guys the circuit works. It can power up to 25 volt laser diodes and itcan provide upwards of 2.2 amps of constant current photos included below https://ibb.co/g4CqXgh https://ibb.co/fDDKqfS https://ibb.co/V3X22yp The laser driver also has an internal safety switch the blue thing it...

    Hey you guys can I ask you something?

    Okay I'm building a Mitsubishi 150 milliwatt laser the diode outputs less than expected light but it still doesn't qualify as burned is my diode dead or my driver toast. https://ibb.co/fpJmynh https://ibb.co/VJPrV4f https://ibb.co/FDzzmw2 https://ibb.co/1rZMFWf https://ibb.co/9Gg8nn8...

    A Plea for EYE Safety!!

    I totally agree with you I might be 14 years old but I have a damn brain in my head here are some of my personal rules: 1rts I don't let ANYONE use my lasers(200mw homemade red 100mw green and 2.2w homemade M140 based) Except me and I always store my lasers without batteries and if I leave it in...

    Need help with lens selection

    So I am going to build a 445 M140 blue laser and I have the lens for short-range burning but I still want to see the beam and do astronomy with it in my private house at my village (My dad owns a house with 10-15 acres of land far from the city ) stuff. Do you guys know of any decent quality...

    Help me choose the right Driver

    That's a shame I thought that for the extra price they might include an IR filter. Edit: Yea do you think the board will be safe for my m140? here are some specs Output voltage: Continuously adjustable(1.25-25V unload adjust) Output current: 3A Max CC range :0-2A (adjustable) Minimum voltage...
