Cool stuff.  2 SPOTs and various add-ons for $499, expected in May.




A Sun SPOT device is built by stacking a Sun SPOT processor board with
a sensor board and battery.

Sun SPOT Processor Board

    * 180 MHz 32 bit ARM920T core - 512K RAM/4M Flash
    * 2.4 GHz IEEE 802.15.4 radio with integrated antenna
    * USB interface
    * 3.6V rechargeable 750 mAh lithium-ion battery
    * 48 uA deep sleep mode

General Purpose Sensor Board

    * 2G/6G 3-axis accelerometer
    * Temperature sensor
    * Light sensor
    * 8 tri-color LEDs
    * 6 analog inputs
    * 2 momentary switches
    * 5 general purpose I/O pins and 4 high current output pins


    * Squawk Virtual Machine
          o Fully capable J2ME CLDC 1.1 Java VM with OS functionality
          o VM executes directly out of flash memory
          o Device drivers written in Java
          o Automatic battery management
    * Developer Tools
          o Use standard IDEs. e.g. NetBeans, to create Java code
          o Use SPOTWorld to manage and deploy applications to sets of Sun SPOTs
          o Integrates with J2SE applications
          o Sun SPOT wired via USB to a computer acts as a base-station

Absolute power corrupts absolutely, but model train sets do a pretty
good job as well
