A Hilbert Curve Cake #3DPrinting #Food #Math @petroffm
Peckish this weekend? Perhaps Matthew Petroff’s recent creation is to your liking?
Three years ago, I entered an Ashley Book of Knots Cake into the Johns Hopkins University Sheridan Libraries’ third annual Edible Book Festival. For this year’s contest, I figured I could apply my 3D-printed Hilbert curve microwave absorber research to craft a cake for Hans Sagan’s Space-Filling Curves book on the eponymous topic. Thus began an endeavor involving thermoplastic, silicone, and sugar.
Next comes a dizzying amount of work with 3D printing, reverse mold making and the like:
While I had hoped that the two-part plastic mold would allow the silicone mold to be easily removed once it had cured, this was an incredibly naive notion. After all attempts to carefully disassemble the plastic mold and remove the cured silicone failed, I ended up smashing the plastic mold to bits in order to free the silicone mold.
Read the whole story on how to make the cake and Matthew’s success on the blog here.

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
