TRIBUTE TO THE TUBE AND TO RADIO
It all started about 100 years ago, 110 to be a little more precise. The vacuum tube was opening the door to what would become the golden age of electronics and lead the way to countless inventions that would change the way we live. While I'm sure none of us go
that far back, many did grow up tinkering with tubes and radios and still do today. Here's a collection of some of our favorite stories about how it all began.
And just for fun, let's hear about your favorite tube or radio project or experience.
Also, once again, thanks to 4D Systems for their generosity and support. Be sure to check 'em out!

THE TRIODE IS 100 YEARS OLD THIS YEAR
This year (2006) marks the 100th anniversary of Lee de Forest's Audion or first vacuum tube triode. This vast improvement upon John Ambrose Fleming's valve changed the world like few other events since.

MAKING SOMETHING FROM NOTHING
Radio and vacuum tubes grew up together from their genesis a century ago, but their history was not a clean, step-by-step process. Theory and experiment took turns leapfrogging each other, mixing sudden discoveries and steady refinements. Their story begins in the Age of Steam...

4Duino-24
4Duino-24 combines the ATmega32U4 8-bit microcontroller used in the Arduino Leonardo with a 2.4" TFT LCD with Resistive Touch and the ESP8266 Wi-Fi module. It is 100% compatible with the Arduino IDE and is fully supported in 4D Systems' 4D Workshop 4 IDE, making development of beautiful Graphical User Interfaces with touch and Wi-Fi capabilities a breeze.

DAVID SARNOFF AND THE BIRTH OF AM RADIO
Sarnoff would take radio out of the exclusive province of the transportation industry and embryonic ham radio hobbyists, and put it into every American home. His stubborn pursuit of technology turned his employer, Radio Corp. of America, into a powerhouse in less than a decade.

VACUUM TUBE IN ITS 100TH YEAR:
Same Old Challenges
The engineering challenges of the hot cathode vacuum tube - an invention dated 1906 - are the same today as they were then. Before Fleming's diode and de Forest's triode Audion, inventors like Crookes, Tesla, and Roentgen had experimented with the magical effects of high voltage in vacuum...

VACUUM TUBES FOR THE 21ST CENTURY
You might think that history is all there is to say about tubes, but it's not so. Hard as it may be to believe, there are still some applications today where a vacuum tube is a better choice than a transistor, and even a few applications where transistors simply aren't an option and a tube is the only choice available.
