Some info about laser:

• Diode from A130 projector
• 1.5Amp current at laser diode (>1w of power)
• 405nm Aixiz glass lenses
• 18650 2800mA*h battery
• boost driver with TPS61030 chip (~85% efficiency)
• It works continuously about one hour until battery discharged

Отлично! Excellent work! Happy to see Mother Russia represented on the laser DIY map.

BTW, just something about the look of that heatsink makes me think it will come to life and run away. I love it though!

Wow that's impressive.

Great build, and your English is fine.

Really impressive home-made driver.

I love the look of it too, very industrial.

It looks like one of the smaller transformers from revenge of the fallen Great beam shots.

I like that beastly heatsink on the end. Looks like you will have NO worries about duty cycle

Yes, it works continuously about one hour without overheat!

If spiderman's laser had a heatsink, it would look like that ^_^
Great job on the build bro. Very unique.

Beautiful laser. Can't wait to build a 445.

No. There are several laser forums in Russia and they do group buys like here. I get the 2 diodes from A130 at the price of only $43 for each

Vsego horoshego.

Thanks :yh:
