A while back we posted a blog about aluminum casting involving 3D printed PLA by Jeshua (3DTOPO). He has used this technique for several of his parts now and decided to post a longer tutorial on youtube plus a shorter video (see bellow) that shows the highlights.
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.
