I keep getting asked to show some examples of Python code running on a Raspberry Pi cluster so here's a distributed task queue using python-RQ, Redis, and 16 ARM cores-worth of Raspberry Pi 3's.
In today's video I be built a solar powered LoRa signal repeater to extend the range of my LoRa network. This can easily be used as the basis for a LoRa mesh network with a bit of extra code and additional repeaters. Even if you're not into LoRa networks all of the solar power hardware in this video can be used for any off-the-grid electronics projects or IoT nodes!
