I haven’t spent much time playing with my lasers lately so I pulled them out last night to make sure that everything still worked.  This is the first (and probably last) laser video that I shot with my 5D MII – one stray beam and it will destroy the sensor.  This is the same basic home built [...]

I just found this message in my spam filter from Laserglow Technologies.  Normally I wouldn’t post a newsletter like this but they have a great deal on the 593.5nM Rigel laser pointer.  They already have the lowest price for the 3mW version @$299 but they are offering 20% off of that.  Just be sure to [...]

I’ve been working on a new laser scanner video.  This uses my same sound-modulated open loop XY scanner as before.  Watch it here or go on over to Vimeo.com for the HD version.  Enjoy!

Find of the day: a fully self contained bar code scanner and interpreter for $10 at Ax Man Surplus.  That’s right, now I can find a way to add things to my Delicious Library library the really hard way.  All you have to do is take this device and connect it to a serial to [...]

Home made laser scanner based off of a Red, Green, Blue and Violet laser module. Roughly 1/2 watt combined output

The Hardware I wanted to write a basic tutorial on how to create some simple but impressive laser effects for beginners (like me!) All this setup takes is a computer, an old Laser Disc player and some wire cutters. I found these parts in an old laserdisc player from Pioneer circa 1980. These were used [...]

XY Laser scanner controlled by my mac. Longer camera exposures a light smoke were used to display the beam in near darkness. This particular setup is generating a tunnel effect. This is done by drawing a circle with the beam and then placing the camera in the center of the circle, pointed towards the source. [...]

I discovered that, under some conditions, 3M Post-Its glow.  They don’t simply glow, but they exhibit phosphorescence.  I did not expect that. I discovered that basic 3×3 post it notes actually exhibit this when they are hit with my 432nm (bight blue) laser.  The exact Post-Its I used are here: http://www.amazon.com/Post-Notes-Colors-Sheets-654-14AU/dp/B0002DOC68/ref=pd_sbs_op_6 See the video after [...]

XY Laser scanner controlled by my mac. Longer camera exposures a light smoke were used to display the beam in near darkness. The cone-like shape is generated by the scanner.  The origin is the narrow end of the cone shape and the beam can deflect roughly fifteen degrees in either direction.

XY Laser scanner controlled by my mac. iTunes is providing source music and the scanners are reacting with the LEFT channel manipulating the X axis and the RIGHT channel manipulating the Y axis. Nine Inch Nails – Only Muse – Endlessly The Postal Service – Such Great Heights
