Hi! I got a free 405 nm "<5mw" laser pointer from Wish (chinese store thing) which I suspect is a lot more than 5mw. Are there anyway to guestimate the ballpark figure on how powerful this thing is? In a dark room, the beam is a little more visible than my 532nm 10mw laser. If I focus the...

RGB 400mW White Laser Light Module/532nm+650nm+450nm/TTL Modulation/Plug&Play Am I right to think that this may be too good to be true? Seller doesn't have much feedback, so I guess that's the first red light. 9 bucks for this, even if it's crap lasers, sounds to me to be too good to be true....

Hi! I'm building a DIY spirograph using red and green lasers, see thread here. I'm looking for a polygon mirror for making a line or liquid sky effect. Perhaps a hexagon mirror with about 1" square sides would be suitable? Must be possible to mount on a motor. Alternatively, I could go for a...

Hi! I'm a noob when it comes to lasers, I'm doing a DIY spirograph, see the thread here. The laser modules I've ordered from ebay has built in drivers, do I need a special driver in order to pulse it with a pwm? I was planning to connect the 5V power supply to PWM, then from PWM to 5V input...

Hi! I'm a noob on lasers, and I'm going to build a laser spirograph using 10 mW ebay cheap lasers at 532 nm and 650 nm. The 532 nm probably does not have a built in IR filter, but I'm going to add a IR filter lens on it to remove the IR portion of the laser. This should hopefully make it easier...

Hi! I'm doing a spirograph project with red and green lasers. One of my design ideas is to have a 4, 5 or 6 sided polygon mirror on a motor in order to be able to create a line (and liquid sky effect if I add a fogging machine). But I'm having a bit of trouble finding this type of mirrors, I've...

Hi all! I'm Lars, a Norwegian living in Philippines. Ended up here as I am gonna be doing some DIY projects like galvo scanners and spirograph projectors with some sprinkles of arduino in there. Nothing for professional use, just for my own and my kids enjoyment... :) In that regard I want...

Hi! I'm doing some DIY projects strictly for home use with lasers. I'm planning to make a good spirograph laser "show" and perhaps a galvo scanner at some point in the future, and perhaps a line scanner. Since I'm basically a noob on lasers, apart from having a few of your typical dollar...
