What this episode covers

Chris Gammell, a hardware developer and YouTuber, explains how he implemented LoRa communication using only the GPIO pins of microcontrollers like the CH32V003 and ESP32-S2, leveraging harmonics and bit-stream synthesis. He details the technical challenges of generating 900 MHz signals from low-speed pins, the role of spreading factors, and the surprising range achieved (over 2.5 km). Gammell also discusses the CH32V003 Fun library, the upcoming CH32V006 chip, and the architecture of LoRaWAN networks.

    102: The Deadly Fluffy Bunny (With WiFi)

    Charles Lohr, an electrical engineer at Unity Technologies and prolific hardware hacker, discusses the ESP8266, a $5 Wi-Fi module that revolutionized his hobbyist projects by allowing direct programming rather than just AT command bridging. He details the chip's architecture, including its external flash boot process, GCC toolchain setup, and limitations like 96KB of RAM, while sharing his experiences building the Neon FM arcade game and exploring audio-visual algorithms like ColorChord. Lohr also reflects on the transition from garage prototyping to commercial production, the importance of community feedback from Hackaday, and the financial realities of being a maker.

    Ep. 5 | LoRaWAN: The Things Network and LoRa Alliance Talk Open IoT

    Wienke Giezeman, co-founder and CEO of The Things Network, and Dave Kjendal, CTO/COO of Senet and LoRa Alliance board member, discuss the LoRaWAN protocol for open IoT. They explain why LoRaWAN’s low power, spread spectrum modulation, and lack of vendor lock-in make it superior to NB-IoT and Sigfox for wide-area applications like agriculture and smart cities. The conversation highlights the technical architecture, including secure elements like the Microchip ATECC608, and the business case for open standards versus proprietary 'walled gardens.'
