Steve Hoefer is a San Francisco-based inventor and creative problem solver with nearly 20 years of experience. He’s contributed projects to the pages of MAKE, including his Indestructible LED Lanterns, Secret-Knock Gumball Machine, and Haptic Wrist Rangefinder. He’s also active in the open source hardware and software communities and is a super nice guy.
One project you’re particularly proud of:
1. The Secret Knock Gumball Machine. A lot of the things I do are for a specific audience or solving a specific problem, but the Secret Knock Gumball Machine has something for everyone and it manages to make candy more fun. It has a feel of forbidden magic to it. It’s not immediately obvious how it works, but you get to see how the trick is done. It’s mechanically and technically pretty simple — you can build your own! I still regularly get messages from people, usually young people, who are inspired by it and have used it as their own springboard into making.
