Get yer lase on

As of last night I got my 16x sony diode all plugged in and turned on! I’ll have some pictures to prove it in a bit. I’m excited, but I really was expecting a bit more danger in the process. It’s bright, and it cuts very thin, dark things. It might even do a decent stencil if cut out of black paperboard, but I was hoping for something with a bit more killing power. I guess I had my hopes a bit high for a laser that cost $30!
I’m still gonna try to mount it to the cnc router and see what it can do. Hopefully I can find a type of wood, or a stain that makes wood “singe-able” I’d be pretty happy about that.
Here’s a pic of the laser diode and enclosure(silver thing in mid-air) and the power supply (thing on the breadboard) Yep, it’s not pretty.

Here’s a pic of the output. Shining gloriously on my hardwood floor.

Lastly, I went out and got drawer slides for the z-axis (at lowes), and bought a hitachi trim router (at ReconditionedSales.com)
With the exception of one L shaped piece of metal I should have everything I need to fully assemble this monster.
If there aren’t any posts for a few weeks, either my body is frozen out in the garage, or I’ve become even more fascinated with the fully functional router.

Treatise on living and loving lasers

In case you haven’t caught on yet. I love projects, and I am always starting a new one in order to abandon an old one. Recently I have become fascinated by the DIY laser movement propagated by the fine people over at laserpointerforums.com. My interest was piqued initially by “lamedust” who posted an instructable here that showed how to build a laser powered stencil cutter out of 2 scanner corpses and a sony16x diode.

My previous post showed my homemade laser driver (ie regulated power source)

I bought a laser focusing tube/heatsink and a sony 16x laser diode from stonetek. Stonetek is run by a frequent commentor from laserpointerforums.com, and is highly recommended over there.

I’m really excited about seeing what this sucker could do if I were to hook it up to my cnc router. Right now it only has an x and a y axis, so this laser fits in nicely without the need for a z axis!

I havent been able to get a precise answer regarding how useful this laser will be. It certainly will not be more powerful than I need! It might be strong enough to burn (but not cut) wood and to possibly cut paper, paperboard, or etch plastic. I’m really excited to find out what it’s capable of.

Here’s to the start of another project, and hopefully the smell of burning things is in my future!
