Episode of
Alicia Gibb (@pipix) joined Elecia to talk about open source hardware, the OSHW association (@ohsummit), using trademarks for quality control, and light-up LEGO blocks. Alicia is the editor and author of Building Open Source Hardware: DIY Manufacturing for Hackers and Makers. It is a handy resource for any manufacturing. Alicia is the director of the Blow Things Up Lab, part of the Atlas Institute at the University of Colorado Boulder. Light up LEGO blocks are available at Build Upons. The LilyPad Arduino has many sewable electronics components. You can find more talks and hacks on Alicia’s personal site,

288: You Got a Screen!
Episode of
Christopher (@stoneymonster) and Elecia (@logicalelegance) discuss embedded systems education and project documentation.Elecia wrote about her love of notebooks on the, for when you don’t have Visio., for when you don’t have yEd (or you want to put diagrams in your comments)We talked about many different documents and tried to note design vs implementation, product vs engineering vs user, and why we wanted them. We didn’t mention mechanical things because, ya know, software engineers. Some documentation we mentioned:Product documentationSchematics with block diagrams and comments. Also a GPIO to function spreadsheet.UI flow when the system has a screens (Balsamiq for wireframe testing UIs)SW spec and design doc: what do we plan to build and what are the tricky partsSW configuration and SW developer docs: how to rebuild the computer that can build the code from scratch, also notes on debugging methodologyUser manual: Usually not written by SW but may need SW’s patient inputCode comments: Functions and files get 5Ws: who, what, why, when, where, and how.Who should call this?What will its effect be? (“What will it do” but not in line by line detail!)How does it work?Why does it work this way?When should it be called?Where are its parameters? (“What” works here too but “where” is nice to remind you to check your memory assumptions.)Repository checkin commentsStyle guide (Such as Google’s or PEP)Manufacturing docs and tests docsAdafruit and Sparkfun both write good documentation, writing to users about how to use their code. Elecia likes Adafruit’s sensor library as a good set of code to review (including how much is in their docs vs their code).
