Great Web Resource for Classroom DIYs

Every educator is always looking for great ways to improve their classrooms and create an amazing learning environment for their students. Everyone knows about Pinterest, TeachersPayTeachers and many other forums. Another fantastic resource for DIY projects, especially electronics, is Instructables. Not only are there thousands of really cool projects to make, but the site forces everyone posting to provide clear and concise instructions. Literally every piece of material and every step in creating the projects are laid out in either step by step instructions or a comprehensive video, lowering the barrier for many of us to build some really great projects. Also, I intended to post instructions on Instructables for some of our more complex prototypes such as the Photoresistor 'Radar Gun' and will link related blog posts to the instructions once completed.
