This page is the central documentation site for the Larson Scanner kit from Evil Mad Science.

Main details about the Larson Scanner kit:

• Announcement article at Evil Mad Scientist Laboratories
• Kit page at evilmadscience.com
• The Larson Scanner is named after Glen A. Larson, who produced the Battlestar Galactica and Knight Rider series, and is responsible for introducing scanning red light effects to the sci-fi TV viewing population of the 1970s and 80s. We coined the term "Larson Scanner" when we wrote an article with instructions for an analog version of the circuit for the Make Magazine Halloween Special Edition in 2007.

Assembly instructions:

• PDF Version (3.8 MB PDF) (Trouble Viewing? Please click here.)

Open Source Hardware documentation for the Larson Scanner:

• Source code is available at Google Code.
• Electrical schematics are here. (33 kB .pdf file)
• The circuit board design is in gEDA, and you can download the design files here. (74 kB .pcb file)
• For home PCB etching, the PCB layout, showing the individual circuit board layers broken out individually with crop marks, is also available as a .pdf here. (124 kB .pdf file)

Hacks and Mods:

• An article on building a Kraftwerk-inspired LED tie with a Larson Scanner kit is here.
• An article on linking several Larson Scanner kits together is here.

More red scanning light projects:

• An analog version of the scanning red light circuit, at Evil Mad Scientist Laboratories
• The analog circuit above was refined and published in Make Magazine, the schematic for which is here.
• MiniPOV Cylon using the Adafruit MiniPov.

Places for questions, answers, and sharing experiences:

• Support forum at Evil Mad Scientist Laboratories
• See also: Archived Forums, with older discussions
• Evil Mad Science Auxiliary Flickr Group where you can share photos of your Larson Scanners
