My first “rack” was made of wood. It monitored, meaning displayed and alerted, on some metrics on my Linux server. And controlled a few lights and the alarm system in my room.
I really enjoyed making the computer control the lights.
It contained:
- A ISA I/O card
- 15" CRT monitor, keyboard and mouse
- Parallel port IO module
- Red and green maritime lanterns
- Yellow strobe
- Stack lights (green and yellow)
- Switch and key switch
- Computer power supply
- Terminal block
Software
The controlling software was written in Visual Basic. It allowed socket connections, making it possible to push commands from the Linux terminal and a “web-UI”.
