I produced a great looking board yesterday on my little CNC mill. The solution was to add $4 worth of fender washers so that I could remove any vibration from the mill table. I’m using the same bits and configuration files between the these two circuit boards. The only thing that changed was the fender washers.
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.
