Grappling Hook Launcher

Grappling Hook Launcher

MIT student Christian Reed built this pneumatic grappling hook launcher. As surprising as it is, there really is no where on the internet where I found any decent instructions on how to make a grappling hook gun. Figuring it would not be that hard to make, I decided to design and make one myself. [Via […]

ShapeLock Robotic Arm

I used some ShapeLock the other day to fix my washing machine but Alexey from Russia used some to make this robotic arm and controller! Each piece was hand crafted out of ShapeLock by hand using hot water and a hairdryer. The electronics consist of an Arduino variant, servos, and some potentiometers for the controller.

How Many Iterations?

How Many Iterations?

As I develop new projects for my classroom this summer, a recurring theme has been to explore just how many times it takes to get a new design right. As far as I am concerned, nothing ever works properly the first time, and it is useful for students and new learners to a subject to recognize this. Programmers call this the iterative process, Engineers use the Engineering Design Process, both of which are relatives to the scientific method. Sure, just about anything can be fixed with duct tape and zip ties, but to get beyond a temporary kludge, you will need to put some time and thought into analyzing the problem and crafting a proper solution.
