Wireless Comms for Arduino on the cheep

This is just a teaser :)
TX/RX Setup
Quick notes:

  • 433Mhz modules from Jaycar (low power, ~AUD$10 per module, should do 150 meters@2000 baud)
  • VirtualWire API for over the air packet handling
  • Custom message chunking (VirtualWire has a small limit on number of bytes per transmission, which is a pain for GPS and timestamp messaging which easily exceed this, especially with a preamble)
