Fwd: The Man Who Invented The Future - Antennas - Wall Wart Monitor - I2C Devices

 
 

THE MAN WHO INVENTED THE FUTURE

 

Who was Hugo Gernsback? The answer depends on whom you ask. "Gernsback published the first science fiction magazine!" a science fiction reader will declare. Ask an engineer and you might hear, "Gernsback ... wasn't he involved in early experiments with television broadcasting?" Others will recall Gernsback's radio magazines. A radio historian will tell you that Hugo Gernsback owned radio station WRNY, introduced the first home radio set (1905), and championed the cause of radio amateurs.

 

8 Channel Thermocouple Data Logger

The PicoScope 9404-05 SXRTO (Sampler eXtended Real Time Oscilloscope). The 9404-05 features four 5 GHz 12-bit channels, each supported by real-time sampling to 500 MS/s per channel and up to 1 TS/s (1 ps) equivalent-time sampling. Both the voltage and timing resolution specifications are characteristics of the highest performance broadband oscilloscopes.

THE MAGIC OF ANTENNAS

 

If you really want to know what makes any wireless application work, it's the antenna. Here, we'll summarize some of the most common types and make you aware of what an antenna really is and how it works.

BUILD A WALL WART POWER MONITOR

 

This self-contained, battery-powered unit measures both DC current and voltage. It accepts four of the most common types of wall wart plugs and, in turn, has four identical output plugs, ready to hook to your project.

WORKING WITH I2C DEVICES

 

Here's a quick beginner-friendly tutorial that shows you how to interface and read data with the popular serial protocol, I2C. In particular, we'll be reading data from the NXP MPL3115A2 altimeter/barometer/temperature sensor. The principles found here can also be applied generically, even to your ambifacient lunar wane shaft positioning sensor of your turboencabulator.
