The point of the matter is Gadgeteer or something very similar is the ultimate next step in device design and customization. It is the equivalent of high level languages or frameworks, it opens device design up to so many more people. What a modular system like Gadgeteer also enables is automation of PCB/device manufacturing where a system takes the Gadgeteer prototype and using the modules and pins used and creates an optimized PCB ready for mass production.
Gadgeteer was the best electronics educational tool that I’ve ever seen or used. In one class I could cover the how a device worked, including the interfaces (I2C, SPI, etc) and have the students construct, code, test and experiment with the device. If a device required multiple classes it was easy to store the uncompleted projects till the next class. Managing modules is pretty much infinitely easier to manage them individual components like resistors, wires etc and in all the classes I taught Gadgeteer proved to be pretty much invincible to student mistakes (ie no fried components or fried students ) In short the world needs Gadgeteer.
Gadgeteer allowed me to get into hardware, I could code my brains out, but hardware wasn’t something I had a lot of experience with (I was the idea guy behind a number of startup companies so being able to think and breath in code was essential). Gadgeteer enabled me to ‘warm’ up to hardware by using my coding skills and some easy ‘framework’ like module interfaces and build and code devices. Once I was confident with that, then I could dive deeper into the hardware and start building my own drivers. This also means that Gadgeteer is the perfect tool for teaching kids about coding and hardware at any level. I had students who didn’t really care about how SPI worked, just that it worked and enabled their code and device to work, great!! I also had students who really wanted to learn at the chip level, which Gadgeteer could also support and modules where wonderful example of how interfaces and chips worked. Combined all of this with an easy to use and full powered development tool like Visual Studio, make helping students a breeze for the teacher. As you can tell I miss Gadgeteer a lot, it was/is a wonderful tool and piece of technology.
