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!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
