This Instructable will show you how to make your own Birthday Candle Mould, so that you can cast all sorts of wax shapes, and use them as party candles – including Lego Minifigures!
I recently finished a detailed Instructable on Casting Objects in Sugru. I found that it is possible to cast Pewter into Sugru (a hand-mouldable silicone putty): First you make a wax mould, and then using a technique known as a ‘lost wax process’, create a second mould for casting the Pewter copy into. The result was a pretty cool Pewter Lego Minifigure.
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.
