Ariel Rocholl has been working with Seed Studio on an affordable handheld spectrum analyzer called the RF-Explorer.
It’s a sort of Swiss Army Knife for monitoring, testing and diagnosing ISM band digital communications. It currently supports the 433Mhz, 868Mhz or 915Mhz bands and other bands in the works. The RF-Explorer is currently in beta with Seeed Studio.
I can see this coming in handy with my water meter reading project.
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.
