I recently came across this neat web app that let’s you draw an equation and have it automatically converted to LaTeX or MathML. You can also submit the eq. to Wolfram Alpha for evaluation. This is actually a demo page for MyScript handwriting recognition software, and it recognizes all the standard LaTeX symbols, including Greek letters and set operators. Super handy if you want to draft up a quick LaTeX expression and can’t remember the special character codes.
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.
