Our favorite low-level hacker Travis Goodspeed knocks it out of the part with this awesome post about emulating USB devices with a GoodFET + MAX342x. Great reading for all of us who’ve suffered through developing USB devices and/or want to try our hand at hacking device drivers. Don’t forget our great USB reverse engineering tutorial here.
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.
