    Adjustable Test Load

    So I've dabbled with adjustable test loads before, using discrete components. However due to the method of operation the actual V-drop would take some time to actually go into effect, preventing it from reproducing the actual way laser diodes function... Aka, It'd be super high resistance for a...

    The ProtoBoost V1

    So... I may or may not have a driver currently in the works. It is my understanding that there is a severe lack of readily available drivers on the market right now, and as such I'm attempting to step up to the plate to, hopefully, fill that void. Now. The ProtoBoost. This is not going to...

    Etching copper PCB with 405 nm or 445 nm laser

    Well, so... I might be getting a 3D printer this christmas. And I can 3d print a head attachment that allows me to use a laser head, to make it into a laser engraver as well. My question, is it possible to etch away copper PCB's using the more high powered lasers, or is that really only...

    Potentially Restarting driver production

    Hey all. I've been out of the laser hobby for about a year now. Before when I was making drivers not a whole lot of interest was shown in them + the tediousness of making them made me stop. If you guys are interested in the drivers linked in my signature, and would totally buy like 5000 (okay...

    Just a reminder...

    To be sure to have proper account security and unique passwords on all of your accounts. Today I had my paypal account hacked by someone in china, who sent some spoof email address approximately $160 in british pounds. Three separate transactions. I'm just glad I caught it before he could...

    gone

    Hey guys. I know this isn't a laser related thing but. Trying to sell this card I got to hopefully upgrade to a better one. Cobbling together a gaming PC is fun. Took it off of ebay, realized eBay fees would have screwed me over. I'm asking $165 for the card including shipping. If you do...

    450 nm 120 mW Laser F/S

    As the name suggests. Gotta round up some money for the girlfriend's BDAY present. As such I am selling what remains of my laser collection. 1x 450 nm laser, in a copper Sinner host. Nice and bright, and the beam is super visible in darker rooms. Uses an E-drive. Should be running at about...

    Name Change...

    Hey all. Planning on changing my username from Le Quack to Hiemal. Le Quack has always been my weird username out of the usual repertoire of usernames I use. I've never been overtly a fan of it, and to be quite honest I'm not even sure why I chose it in the first place. Plus, I also get the...

    Super Boost Drives (5.5+ amp capability!!)

    Hi everyone!! I've been working on this http://laserpointerforums.com/f67/superboost-drive-93418-3.html#post1359424 for a while now, improving the design and making it all around better. They are 12 mm by 9.25 mm. A little larger than the flexdrive. Here are some pictures!! They...

    I wonder about USPS sometimes... Post your mishaps here.

    This is how I normally received packages from OSHpark. Usually takes a day. Lake Oswego is literally 30 minutes from where I live. What in the hell is going on here? Been to two Portland zip codes, and now it's at Seaside Oregon which is 2 hours away?.... I don't understand their logic...

    Touch Based Switch Ideas.

    Hey all. Thinking about some interesting ideas for a new style of switch for lasers, but I have a few questions about it. So I found this IC that allows you to basically create a switch based off of touch and proximity. Now the first thing that came to my mind is, how cool would it be to be...

    Fully Adjustable Test Load Prototyping...

    Works via this schematic. Imgur Rather simple to make. Uses one op-amp, one MOSFET, three resistors, a potentiometer, a 9 volt battery, and one silicon diode. And boom. You have a fully v-drop adjustable test load. Stays stable regardless of current through it, only changes a few...

    SuperBoost Drive (5.5+ amp boost driver)

    I have a driver that's currently awaiting me buying the parts for. However, I want to gauge interest on it before dropping any more money into this driver business. Don't say or comment anything except if you would buy something like what I'm bringing to the table. Okay. That being said...

    Some help, advice, or whatever...

    Hello guys. I'm not normally one to beg, nor ask for assistance when it comes to these things but quite frankly, I'm scared. I recently moved to Oregon, from New York to live with my fiancee in her parent's house. All has been well, but then today her mom had dropped the fact that...

    FS: 520 nm 70-100 mW Forest Green!

    Hi all! I'm going to sell my 520 nm laser I got a couple months ago. I had fixed it up (there was a single loose wire inside the build) after I had gotten it second hand. The original FS thread is here: http://laserpointerforums.com/f39/fs-100mw-forest-green-pl520-ms-envy-host-89836.html...

    Speech Jammer/Interruptor Instructable

    Hey guys; I wanted to share my instructable with you all that I made a day ago. It's already been featured on the front page (I've also submitted it as a tip to hackaday, Gizmodo, and lifehacker). I'm really hoping I can win the audio contest, and hope anyone who enjoys the instructable could...
