Yes, true, on diode is 5,96V, half of supply voltage. But on board si small trimer VR1, it should be a trimer for current. Is possible to produce laser power meter at home?

Hi everyone. I want to ask you about true output power of laser engraver module. I bought this laser module. https://www.aliexpress.com/item/32562052620.html It should be a 500mW power laser, but if i am measured a input current so it was only 290mA, when i turn off laser by a TTL, so input...

Good day. Has someone good seller with Green lasers 303? i want to buy one good piece, but i have afraid that i will buy bad piece. I will be glad if someone send me verified link on green laser 303, thanks. ebay, ali...., etc thanks

Hi, i already have 405nm 125mw laser with stepper motors, but MCU is not my, i am bought it. everythink others is my. But offer still pays. If someone has some codes on patterns with stepper motor, i will be glad to see it. Thanks. https://photos.app.goo.gl/xGiMp1CcBUqDQUTr7

My some Lasers https://photos.app.goo.gl/luGYBeq0I3LofRWx2

Hellou , sorry for OT. I trying find some examples for stepper motors, but unsuccessfully . Please, can you share with me some link on examples for stepper motors? thanks.

Thanks guys for comments. As you can see I have some lasers, also i have one with stepper motor, but i want build one purple with my own program. I am already tried something write, but i am not finished it. 4 years ago. And now, it is only for me pleasure. When i have a some little time, so i...

Hi friends. I would like build laser with stepper motor. I have everything except program for processor. I know to programming, but i don't know how i have to write program for stepper for different patterns. I use PIC18F46K22 this is not important, i know to modify whatever source code for my...

thanks for interest. I am did first tried with LM317 with solid setted output current. But then what you can see on video, is only voltage supply and one 5W resistor in series and i'm did set voltage until was 0,9A on output.. i hope that you understood me. I have a lot of skills with...

Good day. https://www.ebay.com/itm/1W-1000mW-Laser-Diode-Blue-445nm-TO-18-5-6mm/171922444978 I have this same problem. When connect to power source, so after short time brightness of laser diode are decrease. i send video i use LM317 as CC or also i try to connect straight to source via...

Good day. I have this same problem. When connect to power source, so after short time brightness of laser diode are decrease. i send video i use LM317 as CC or also i try to connect straight to source via resistor. But in both cases is same behavior.

Hi. Where i can buy a front surface mirrors? I need for laser projector with stepper motors. Some rectangle pieces 1cm x 3cm. thanks

What is DTR?

Hi. I am bought few years ago this Red Laser Module - Focusable Dot (3.5V~4.5V 11.89mm 5mW) - Free Shipping - DealExtreme it's good choise join it with this?? Mitsubishi 658nm 660nm 300 400mW CW Red Laser Diode LPC 826 | eBay or what combination is better? thanks.

yet two picture, size and max current. i will make some testing tomorrow. http://fastimages.eu/images/pa231863.jpg http://fastimages.eu/images/pa231864.jpg http://fastimages.eu/images/cc.gif

Hi, i built driver 10 minutes ago. input 5V (max 5,5V) output 0-500mA http://fastimages.eu/images/dsc03473.jpg http://fastimages.eu/images/dsc03471.jpg

what's happens? nobody told me, how i have control stepper motor for laser, however everybody told me, how i have turn with it, but i know it !

ok, thanks, I will not attempt to make a visible laser beam. I will to try it to sell. thank.

hi. a few years ago, i bought this lasers. but i'm made mistake. i bought this: XBOX360 HD-DVD 405nm Diode Lens DT0811 - xbox360 Laser Drvices - website closed for update some lasers, i'm sold, and some i have. it's possible do with them good laser? how output mW they have? thanks.

i'm right now bought this laser diode. i won auction for 6,51$, nice LPC-826 Mitsubishi 658nm 660nm 300 400mW CW Red Laser Diode LPC 826 | eBay and how much current i have use? yes, i know, that they write that i have use 400mA but on other site is wrote other current.
