Getting Started with RTL-SDR and SDR-Sharp and CubicSDR

and lets you charge-and-boost at the same time without any interruption on the output so its fine for use as a "UPS" (un-interruptable power supply)

but no additional knowledge of electronics is presumed or required and it should take about an hour to build

you can easily turn the Grove into a LoRaWAN® sensor
