At makezine.com, I stumbled on this gem of a book titled “Making Things Talk”

It is packed with 26 electronics projects that involve getting these tiny computers to talk to each other and the internet over both wired and wireless connections.  I have ordered all the requisite parts, and when purchased, they amount to around $280.  I am looking forward to summer vacation when I get to go through each of these projects one-by-one:

1. Making a computer “mouse” out of a stuffed animal monkey and flex sensors.
2. Making the monkey wireless
3. Negotiating in Bluetooth with the BlueSMiRF module
4. Setting up a networked webcam
5. Connecting a microcontroller to the internet without a computer
6. Networked Air Quality Meter
7. Networked Games
8. Infrared Communication
9. Radio Communication
10. Duplex Radio Communication
11. Bluetooth Communication
12. Broadcasting Messaging
13. Directed Messaging
14. Infrared Rangefinding
15. Ultrasonic Rangefinding
16. Reading Signal Strength with XBee Radios
17. Reading Signal Strength with Bluetooth Radios
18. Reading the GPS Serial Protocol
19. Heading with a Digital Compass
20. Attitude with an Accelerometer
21. Color Recognition with a Webcam
22. 2D Barcode Recognition with a Webcam
23. Reading RFID Tags
24. RFID and Home Automation
25. IP Geocoding
26. Email from RFID

OK, I wont be making each of these.  I will get an idea halfway through and take off and work on that.  But it should be fun!

While I do not know precisely how this distiller works, in general a distiller would boil the water, collect the steam in baffles and let it condense into water and flow out of the machine. 

Dean Kamen claims that this machine cleans all forms of dirty water.  I am not sure how this is possible without membranes or filters.  Any volatiles in the water with a boiling point less than or equal to that off water will boil off and possibly be collected in the baffles.

Regardless, it is an impressive machine as it will save thousands of lives.

I am going to write a few other versions that will complement my BirdPlanner.com site. The first will be a modification of the above where the user can enter their latitude and longitude to get birds that are present in that locale. That way people can prepare for their birdwatching trips.

I will also try writing one which is a Bird Identification Quiz. It will be a multiple choice quiz. I can vary the difficulty by sampling from birds of the same genus, from the same family, or from the whole set of birds.

This is a fun way for me to become familiar with the computational technology. The google gadget is just an XML file. The tag <Module> identifies it as a Google Gadget.

The remaining XML has three parts:

1. <ModulePrefs>, which encodes the properties of the gadget.
2. <UserPref>, which encodes the user information.
3. <Content>, which encodes the content.

My gadget is pretty straightforward.  There are no User Preferences, so I just have the first and last sections. 

You can look at the xml code here.  You will see that the workhorse of the content section is a php file that emits an html file.  In this case the gadget simply holds a simple web page.

In the future, I will write more details about how all of this works.
