The real beauty of the Raspberry Pi is you don’t even need any extra hardware to do all sorts of cool things. We already have a full-featured Asterisk PBX running on the RPi complete with Google Voice for free calling throughout the U.S. and Canada as well as free worldwide calling through iNum access points. http://nerd.bz/QTtlIB You can take it for a spin by calling 1-843-284-6844. With a little luck, we’ll have the complete writeup on Nerd Vittles later next week.
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.
