VFD Clock

Bedside clock with extended info

I'm a sucker for old display technologies, so on my arduino binge I built a bedside clock capable of displaying generic information, with long line scrolling and whatnot. The design is fully PoE, so the finished clock just needs one cable.

In this repo:

• Arduino code for the clock logic, handles fetching data from the server and VFD control.
• Eagle schematics for the clock control PCB
• Housing DXF for laser cut housing. The design is intended to be cut on a 6.7mm material.
• Server code manages actual information fetching (checking my unread mail, getting the price of bitcoin)

Partlist

• Atmega 328P (along with 16MHz crystal, 2x 22pf caps)
• Silvertel A9700 PoE module
• ENC28J60 ethernet PHY
• RB1-125BHQ1A RJ45 jack with magnetics
• LM1117 3.3V regulator (for ENC28J60)
• VFD with serial interface (Here I'm using a Noritake CU20045SCPB-T31A)
