With a name like that how could we possibly pass up featuring this one? Truly a hack, this pancake making robot was built in under 24 hours. [Carter Hurd], [Ryan Niemo], and [David Frank] won the 2015 Ohio State University Makethon with the project.
The gantry runs on drawer sliders using belts from a RepRap. The motors themselves are DC with encoders. [Carter] tells us that since most 3D Printers are build on stepper motors this meant they had to scratch-build the control software but luckily were able to reuse PID software for the rest. Get this, the pump driving the pancake batter was pulled from a Keurig and a servo motor is used to kink the tubing, halting the flow. We are amused by the use of a Sriracha bottle as the nozzle.
It wasn’t just the printer being hacked together. The team also built an iPhone app that lets you draw your desired pattern and push it to the machine via WiFi.
Inspired yet? We are! If you’re anywhere near New York City you need to bring this kind of game to our Hackathon on May 2-3. One night, lots of fun, lots of food, and plenty of hardware. What can you accomplish?
