This software stores its data as text files so it is easier to export it to another format when necessary. The documentation is surprisingly good and available through the Syntax:Dokuwikilink on the left side of every page.

Please keep in mind this wiki is essentially my notebook. I fix errors as I find them and clarify things as I can, but there is still stuff on here that is confusing and some that is just plain wrong. With that in mind, here are a few of the better things I’ve written.

• Statement of Purpose
• An explanation for my Tuggle Tuner Calculator
• CE Numerical Methods Term Project Due 11/29/07 (Please ignore the stated conclusion. Although it is not perfect, this hydraulic model of a crystal radio does appear to work properly, but explaining this was beyond the scope of the assignment.)
• Concrete Project 2 Final Report
• Economic Analyses: Solar-electric Coffee Roasting and Brewing and Homebrew: Extract or Whole Grain?
• 4/10 Landmark Term Paper Due presentation_1.ppt presentation_1.odp
• Engineering Sustainability: an Ethics No-brainersustainability.ppt
• Ethics Presentation Proposalethics.ppt
• http://waggy.org/electronics/hackaday-challenge/
• POV-Ray Stained Glass Texture

The rest of this page has links for my convenience.

• Handy Calculators: Capacitor Impedance, Inductor Impedance, Tuned Circuit
• Passive Filters and Narrow Band Pass, 6 dB Schematics and 12 dB Schematics

Consider low power as less than one-tenth of a watt (< 100 mW).
