Build a DMX FeatherWing to Control Lights with a Feather M0
This project uses an Adafruit Feather M0 board to control a group of RGB lights using the DMX-512 protocol. We’ll build a DMX-512 FeatherWing and connect it to the Feather M0 and a Particle Ethernet FeatherWing. Finally, we’ll develop a web-based GUI to select different RGB lighting effects and control the lights. Continue reading

PoE-Powered RGB LED Floodlight
This project uses a Silvertel 802.3at Ag5300 PoE+ module with a built-in isolated 24 V DC/DC converter to power a 10 W ColorKinetics ColorBurst 4 RGB LED floodlight. The Ethernet cable and light plug into a small power / control board and PoE+ powers the floodlight and Art-Net UDP packets control the light. Continue reading

PoE-Powered VFD Tube Clock
This is a vintage VFD tube clock that uses Ethernet for both power and data. The power is provided using 802.3at PoE+ and a Molex PD Jack that contains both integrated magnetics and a PoE Type 2 PD controller. The IP stack runs on a Microchip PIC18F67J60 microcontroller that has an integrated Ethernet MAC and PHY. The IP stack includes DHCP, DNS, NTP, and LLDP functionality. Continue reading
