Re: Great deal of 2000mW Circle Straight Type High Power Blue Light Laser Pointer I knew the actual power of it before i bought it and in the end I paid 70$ for a 1 watt laser. That seems fair to me.

Re: Great deal of 2000mW Circle Straight Type High Power Blue Light Laser Pointer These are marked up lasers from Aliexpress, they are around 80$ on there. About 800-1000 mw maybe less. I got one in the mail today, identical...

I've been shopping aliexpress a lot lately. I stick to sellers and lasers with lots of feedback as this is something I don't believe they can spoof. I have only had 1 dispute and I got all my money back from it through the escrow service. I buy mostly cheap ones but as my confidence in the site...

So you're saying that's a cheap garbage driver?? :cryyy: lol That actually doesn't surprise me.. I plan on building a buck regulator soon but I will check theirs out for sure. Thanks

The tether on my laser broke tonight and the laser hit the floor and no longer works. I opened it up and found a piece of the diode rattling around. I'm not too hung up over a $30 laser but I was wondering if the driver is worth keeping. The large chip is an op amp.. The back reads...

This is the fun half of my desk, the other half is just a computer for porn. I mean work. Usually its a slew of interconnecting wires and components with various monitoring and debugging interfaces tied in the midst of it all with data sheets pinned all over the walls, but I'm between projects...
