    Power-up driver NUGM03 Diode

    This driver does not have a variable resistor. The original resistance is 200 milliohms. If a 470 milliohm resistor is attached to this resistor, the value will be about 140 milliohm. Because of the lower resistance, the current value will increase to about 1.75A. Since the current that can flow...

    Power-up driver NUGM03 Diode

    I have decided to power up this driver. The current value before power-up is 1.22A. Install a 470mΩ resistor. The current value is now 1.72A. The power meter reads 899mw. Currently, there are few places where this driver is available. I like this screwdriver very much.

    Hi-POWER 100W LED 3D-Printer

    I spent 6 months creating this LED light. It is written in Japanese. I used Arudino and made a flashing program but but for some reason it did not work well. I gave up on the flashing program. I hope you can see the video.

    74W High-Power Laser

    The title of the video is 74W Laser, which casts a laser beam into the dark. At the beginning of the video, the camera was shooting with the lens cap on. The screen is shown dark for a while, but it will be displayed after a while.

    74W super power laser produced by 3D printer

    It took me 5 months to complete my 74W laser. I was finally able to complete it. The body was made with a 3D printer. I designed, printed, and produced everything myself. YOUTUBE is in Japanese. Thank you for watching.

    trinh hong phuoc

    I have been communicating with trinh by email until recently, but I have been having a lot of trouble with him. He probably won't do laser trading. He didn't even send me the product I ordered, so I refunded my money.

    NUBM31T 95W 455nm

    Are there any focusing lenses on Aliexpress or eBay that can be used with the NUBM31T?

    NUBM31T DRIVER explosion !!

    Positive and negative polarity is not wrong. During testing, the capacitor suddenly exploded. The driver was so hot that it could not be touched by hand.

    NUBM31T 95W 455nm

    I have a host for 100W that I purchased from trinh. I am going to use it to produce a 100W laser. It has a large aluminum heat sink and an air cooling fan.

    NUBM31T 95W 455nm

    I think it will light up this way, but the problem is How many settings should I set for the voltage and current?

    NUBM31T 95W 455nm

    I came up with this wiring scheme. It's a way to use two converters and connect them in parallel. If I do it this way, can't I use a small 250W boost converter to light it up? If I use one converter in series, I would need a higher voltage. I thought this would work with a lower voltage. What do...
