1. KB1DBL demonstrated a pair of low-cost Particle microcontrollers capable of cellular, wifi,
Bluetooth, and mesh networking. The mesh-only node ($15) was able to use the cellular
node ($59) as a gateway to get its data to the Particle.io cloud service ($3/mo). Both units
were powered by Li-Po batteries and capable of continuous multi-day operation without
recharging.

2. WA1MJS demonstrated a Raspberry Pi-based DMR hotspot by using it to access a Yaesu
Fusion chat room via an HT. The hotspot was powered by a USB battery bank and used
wifi or Ethernet for network connectivity. It was capable of DMR (P25), Yaesu System
Fusion, D-STAR, and even POCSAG (alpha-numeric pager!) operation. He administered it
via a web interface using a laptop.
