>Just when I thought I had my spring projects planed out, I met a group of local “maker” types at a group called FAMiLab. The people at FAMiLab run the geek spectrum from “makers” to networking guys, artists, etc. I went to meet them a few weeks ago since they have a reprap and while I was there, they were discussing the Great Global Hackerspace Challenge (GGHC) sponsored by element14. I’m not a huge fan of the term “Hackerspace” since the general public still thinks that “hacking” is an illegal act, but the wikipedia definition for Hackerspace captures the right spirit:
A hackerspace or hackspace (also referred to as a hacklab, makerspace or creative space) is a location where people with common interests, usually in computers, technology, science or digital or electronic art can meet, socialise and/or collaborate. A hackerspace can be viewed as an open community labs incorporating elements of machine shops, workshops and/or studios where hackers can come together to share resources and knowledge to build and make things.
I started brainstorming with the FAMiLab group one night on their project for the GGHC, and well, now I’m part of the team.
There are ~30 worldwide hackerspaces entering projects. The primary requirements for the project are:
- Supports education
- Uses a microcontroller
- Uses a portable power source
- Cost of the design
1) Writing Arduino Libraries
- This seems very simple, but it will test your C++ skills. Specifically the Wire library uses callbacks, and doing the callbacks into member functions of my library class…ug.
- #includes – they don’t work in libraries in the Arduino build environment. Why is beyond me, but they don’t work. Your end sketch must have your library includes AND any includes that your library needs as well.
- Your library code must be in ../[arduino-ide-folder]/libraries to be compiled and included. This makes working using a source repository like git a little more complicated. I used windows symlinks to create a folder under libraries that pointed to my rep library folder.
