In addition to the transition of the platform to open-source, Sun is also now offering discounts for educational institutions for individual and bulk purchases:The Sun SPOT Device is a small, wireless, battery powered experimental platform. It is programmed almost entirely in Java to allow regular programmers to create projects that used to require specialized embedded system development skills. The hardware platform includes a range of built-in sensors as well as the ability to easily interface to external devices.
Sun SPOT technology is being adapted by the community for a number of purposes. Bruce Hopkins has written a Sun Mobility Tech Tip on utilizing Sun SPOTs for ultra-low bandwidth communication:"We created this technology to inspire students and educators to develop new, creative and useful applications—it's the core of Sun's vision for Project Sun SPOT," said Roger Meike, research director at Sun Microsystems Laboratories. "Our decision to open source Sun SPOTs under a GPL V2 license reflects our commitment to support our growing community of developers, and our new pricing will enable educational institutions to bring this technology to students worldwide. Innovation happens everywhere and Sun is excited to be delivering new tools and technologies that will both inspire and facilitate development within new communities."
Terrance Barr also recently presented a number of video examples of individuals utilizing Sun SPOT technology in a variety of ways including:In the U.S. Department of Defense as well as in commercial industries, there are several applications that need wireless communication at low data rates (and consequently with low power consumption). For instance, most modern vehicles now contain tire pressure monitoring systems.
Have you ever wondered how the tire pressure sensor data is sent from each of the tires to the vehicle’s internal embedded computing system, and ultimately to the dashboard? Obviously, there are no wires to connect the sensors in the tires to the data bus in the dashboard. So, as you can imagine, there must be some mechanism available in order to retrieve the sensor data from the tire pressure sensors. Additionally, such a mechanism must be wireless and be able to operate for a very long time without interruption.

- Processing telemetry.
- Sensing orientation.
- Processing radio-wave signals.

Squawk is an open source virtual machine for the Java language that examines better ways of building virtual machines. Most commercial virtual machines are written in low level languages such as C and assembler. We believe that virtual machines can be simplified by writing them in a higher level language, and further simplified by implementing the VM in the language that the VM is implementing.For information about obtaining Sun SPOT devices visit the Sun SPOT products page or read further about the educational discounts.

Interesting device and ridiculous pricing

I think that these devices are really interesting ... but it is ridiculously expensive!
In addition the price in euro is a lot higher that the price in USD. Someone at Sun hasn't checked recently how much the euro is worth...
Prices: US$550.00 or €627.00 plus applicable tax and shipping.
€627.00 == US$909.09 (at 1 US$ = 0.6897 €)
It is 65% more expensive to buy a spot in Europe than in the US (and it doesn't includes shipping and TAXES).

I agree James...
What the hell are they thinking with that pricing? Even $550 is a lot to ask for that. That must be about a 1000% markup on the materials. We shouldn't be surprised though. It's typical of Sun to shoot themselves in the foot out of the gate. If Sun was a sprinter, the starting gun would be loaded with real bullets and pointed right at they're sneakers.

I agree these are a bit pricey and I'm hoping the price comes down eventually. For more reasonably priced embedded hardware I recommend taking a look at Arduino (www.arduino.cc/). They don't run Java but they're cheap ($35), open source, very capable and have a strong community. Also, you can wireless enable them with XBee for around $35 more.

I could respond in a variety of way here, but instead I have posted a detailed response on my blog.
