More Home-Made Hardware

Summary:

Using Linux, it is possible to design and build a complete electronics
project prototype, both hardware and software.  From concept to the actual
running prototype, a small home-made two port terminal server and relay
controller will be demonstrated controlling a headless Linux machine.

Terminal server hardware specifications:

- ARM7 32-bit ~50Mhz Processor w/256K Flash
- 10/100 Auto-MDIX Ethernet
- 2 Serial Ports
- 4 Low Voltage Solid State Relay Drivers
- Embedded web server
  - General device configuration
  - Control relays
  - Manage serial ports
- Embedded telnet servers (1 for each serial port)
- Dimensions - 2" deep x 4" wide x 1" tall inside project box

Primary topics of discussion include:

- Nifty hardware gadgets, making the terminal server itself
- Hardware design and implementation using Linux
- Software development for ARM processors under Linux
- Linux headless server operation  (Look Ma, no monitor!)
