Motöri the Plotter. I have always admired pen plotters since the first time I saw one. I was a little kid back then and I didn't even know a thing about computers. Unfortunately, as I grew up, the plotters got completely phased out so I never really had a chance to play with a real plotter. Now it was about time I'd built my own plotter. With black jack and hookers. Plotter Basics A traditional flatbed plotter, of which Motöri is an instance of, consists of a 2D coordinate table which delivers a pen-holding carriage to any position within the plotting area. The gantry consists of a frame that supports rails or guide rods that constitute the X axis. XY plotters share a lot in common with 3-axis CNC machines. The things that travel along the axes are moved with motors. Parts Motöri is built from parts salvaged from old printers and scanners, this puts some constraints on design decisions.

There is a blog post on it, information on the wiki and a lot of discussion on the forum. This was designed as a "self replicating" laser cutter engraver'. What this means, is all of the high tolerance complicated parts can be made on a laser cutter. This is not a mamby pamby little diode laser than can slowly cut through a piece of thin black tape. This was designed to be a dirt cheap, but fully capable laser cutter. The buildlog is presented blog style (most recent entry first) if you want to go view it the other way click here...

Stephen Hobley - The Laboratory. What is a Laser Harp…?
Now with dual core Arduino's... The laser harp is a musical instrument made of light. A fan of beams shoots up from the floor into the night sky. The performer can create music by placing their hands in the beams. Not only does “breaking” the beam produce notes, but sliding the hand along the beam will also change the sound. The harp does not produce any sound by itself, but creates MIDI data that can be connected to any modern synthesizer. The laser harp concept was invented by Bernard Szajner and used extensively by Jean-Michel Jarre, and more recently Little Boots. Zach Radding Homebrew Laser Cutter.
