Perpetual Battery-Free Weather Station

Perpetual Battery-Free Weather Station

It’s now possible to build remote, low-power microcontroller projects that can operate indefinitely without batteries and still not crash, even if power is interrupted. Let that sink in. As an example, we’ll show you how to build a LoRa-based weather station that’s powered solely by solar panels. Its code is written in CircuitPython, running on a […]

Working with “wireless” LEDs feels a bit like magic. These tiny LED assemblies can emit light without directly connecting to a power supply. The secret to their energy source is a nearby wire coil in which a high-frequency oscillating current generates a fluctuating magnetic field. Each induction-powered LED is attached to its own tiny wire coil, […]
