Over on Medium, Jessica Hogan posts how to make a silicone mold and candle.
Making silicone molds and candles is easy! I started off with a 3D print of a 3″ cactus from thingiverse.com. You can use lots of items to make a mold, I recommend using something small and simple for your first attempt.
You will need a few materials to create your mold: a hot glue gun, extra glue sticks, a small cardboard square, sturdy card stock, a paper cup, popsicle stick, scissors, and a ruler is helpful but not necessary. Most important is your silicone!
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.
