    Laserpointerpro.com ~ 100mw-6000mw Laser Pointers, UP TO 50% OFF

    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.

    Aliexpress good deal on 532

    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...

    Apology for typos, grammar and spelling on posts

    I hope this isn't too much of a Necro post.. I can verify that Canadian Customs has a black list, I would expect most other countries do too. I am on the aforementioned list for Canada. I do a lot of online shopping and pretty much every package I get from out of the country has been opened and...

    DIY Time lapse Camera , Arduino Based

    Awesome! I recently did some testing of Arduinos time function (millis()) paired against a DS1388 RTC chip. It was within a second after many hours... Then my laptop shut off and I didn't feel like repeating the test.. I would love to see some time lapse shots made into a video. +rep

    Worth keeping?

    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...

    Post your: Desk/Work area!

    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...
