Howto:Build your own Panel or Cockpit - Gauges, Instruments, Radios and Controls
More content to follow, but for now:
from Guy Carpenter in Australia:
Each item has a number of different parts. You'll need to become familiar with a few types of electronic devices and construction methods in order to make items in your cockpit look like the real thing. Here's a list of the low level components you'll find inside a typical simulator.
To get started, I planned to do a quick prototype for each of the devices listed below. You'll find more detailed information on this in Prototyping
|Seven, Fourteen or 16 Segment Numeric and Alphabetic Displays
|Maxim MAX7219 Modules drive up to 8 7 segment displays. These can also be used for 14 and 16 segment displays. Finding smaller 14 and 16 segment displays to match may be problematic.
|Toggle, Rocker, Rotary and Key Switches
|Microchip MCP23xxx 16 bit Multiplexers are bi-directional and can be used
|Rheostats, some with built in switches
|Test Encoders to determine how fast they need to be read. Depending on timing, provide support for them using
|Find a cheap one to prototype with...
|Two approaches are possible: Multiplexers driving one LED per output, or MCP23xxx
|Multiplexer or GPIO output driving an amplifier.
|Moving needles in gauges and instruments
|1 DAC or PWM output per meter movement
|Got any ideas?
