From the sun SPOT website.
Sun SPOTs (Sun Small Programmable Object Technology) are small, wireless, battery-powered devices developed at Sun Labs to explore the next frontier of network computing. These devices can be used in a wide range of applications including robotics, environmental monitoring, asset tracking, proactive health care and many others. Sun SPOTs are powered by a specially designed small-footprint Java virtual machine, called Squawk, that can host multiple applications concurrently, and requires no underlying operating system. Stackable boards include application-specific sensors and actuators such as accelerometers, light detectors, temperature sensors, LEDs, push buttons and general I/O pins. The devices can be duty cycled to run for months on a single charge of their rechargeable battery.
In human language - Its using Java to work with embedded devices. Currently we are using "difficult language" like C or PIC..
The kit is $299.
Wonder can I buy the device here in Malaysia???
