Saw this on youtube and had to share it XD WORLD'S MOST POWERFUL NINJA TWIN ACADEMY LASER PEAKS EVERYONE ! - YouTube

So last week I was packing my laser stuff up into my truck to take to a friends house. Then I realised I forgot the ice for the cooler. I set the laser stuff on the tailgate and went to get the ice, I come back and leave for my destination. I go to drive onto the highway and forgot it was...

Found the charger to a better camera with sustained shutter feature: Shutter open for 15 seconds In basement with the only light being the laser: Closeup image: Upstairs with laser light only: Upstairs with small background light: Upstairs, different angle: outside, shooting across...

Was very curious about this one. Has anyone here tried setting up a powerful laser pointer in one spot and melting a small hole through several feet of snow? Certainly someone has thought of this before!

Heya everyone! Just completed my brass bar laser! At the time of this post, I don't have actual pictures, but here's my finely edited HD video of it. I filmed and edited a full video showing how to make this, but its not complete yet, so here's just the tail end of the video: Homemade 1.2...

Hey everyone. I've been wondering about this one for a bit now since returning to the forums... Does anybody still use these Dorcy Jr flashlights as hosts nowadays? Anyway, I've taken the black plastic that covers the driver off, and soldered some wires to it (I've lost the LED holding...

Hi all. I noticed my (very old) video of "how to build a laser diode driver" was passed around a bit here on the forums. I thank you for finding the video useful. The only thing is, I feel the video wasn't descriptive enough. I was 17 when I made it and I didn't know how to cover all the...

so when I was putting together my driver, I accidentally bumped my 12v battery's wires together with my elbow. Of course, short circuits are bad, so I quickly tried to yank off the wire the instant I heard the spark. As you know, when you short circuit a lot of power, it welds the...

Hi all. I have this unit a neighbour gave me in exchange for me giving/installing a 5.1 sound system in his garage. Here's the power supply. I've never shopped for one, so i don't know what the specifications mean. Would YOU trust this with a laser diode? I think it'd be a great testing...

Hi all. Figured I'd share my music. My piano/strings compositions: Expressive Piano Solos by Joseph Oscapinski on SoundCloud - Create, record and share your sounds for free note: If you want a really good demo, listen to piano/strings 1, track number 2. My computer-created tracks...

Hello all. I've searched many results and threads on laser driver test loads, but can't find what I need to know. I will be using one of DTR's 1W 445nm diodes in a laser project. I've built an LM317 driver. The circuits I've seen vary from the senkat red diodes, to blu-rays. Since there's...

Making this as simple as I can. I'm not a super pro on this circuit. Please provide feedback and I'll add to/change. My goal? Be as minimal and cheap as possible. Hoping to make it so small that it needs no board, just parts soldered to parts with lots of heatsinking.

Hello all. I've recently come across a solid brass bar. It is very heavy and would make a good (lab laser? What do you call desk lasers?) unit for placing and playing with. I've decided I don't want handheld, I want steady desk piece. 1080p HD video of the product in question I wish to put...

Hello all! Sadly my last account was hooked to an email I no longer have... Anyway, I used to come here a lot and make lasers 4 years ago, for my own purposes. I moved houses and now have a full electronics work desk for the first time, and wish to get into laser making again...
