We think of factories producing iPhones, IKEA flatpacks and Infinitis, and as ID’ers we have an idea of what those production lines look like. But chances are you’ve never been inside a factory that makes cakes and desserts. Unifiller Systems, Inc. is a company that creates cake-decorating machines and food processing equipment, and their “sizzle reel” is pretty fascinating:
Once you’ve seen those machines above in action, it makes sense that circular cakes would be filled and iced on a turntable. But how do they get the filling into rectangular cakes, which don’t have rotational symmetry? Surprisingly, for sheet cakes they use a “split and fill” technology that slices the cake horizontally while simultaneously injecting the filling (see it in action around 0:28):
In that vid you probably caught a glimpse of that tablet the guy was scrawling on, with the robot arm copying his lines onto a cake. That machine’s called the Unibot, and it’s how they achieve that handwritten look with icing:
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
