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

The Annoying CAPS LOCK Warning Buzzer

The only way to make CAPS LOCK even more annoying was to make it audible! Now never type a password in all upper case, join 500 lines together in vi, or turn a harmless forum post into an ANGRY SCREED … Continue reading

PIC16F1459 USB Stack Light Controller

After using the PIC16F1459 to build numerous USB HID input devices including a giant keyboard, a tiny keyboard, and a big red button, it was time to see if the PIC16F1459 could be used to control outputs too. Sticking with … Continue reading

Piggybacking USB onto an Industrial Push Button

In this project, I mount the electronics from my single-key USB keyboard project to the back of an industrial mushroom push button switch. The finished big red button now activates my screensaver with a single overly-large button press. The biggest … Continue reading

Presenting the Single ESC Key USB Keyboard!

After building the “awesomely impractical” giant three-key keyboard, I decided it was time to build something a bit more practical—presenting the single ESC key USB keyboard! This keyboard has exactly one function which is to provide an optimal ESCing experience … Continue reading

PIC18 Four-Channel DMX Relay Controller

Halloween was right around the corner and I needed a timer with a bunch of relays to trigger some store-bought props and a fog machine periodically. (Mental note: read fog machine specs carefully—not all come with timer remotes.) My first … Continue reading
