THE RADIO STATION THAT BRIDGE BUILT

 

It was 1923, and radio was the phenomenon of the day. Over 600 broadcast stations were on the air, and Americans bought 100,000 receivers that year. (Sales would jump to 1,500,000 in 1924.) Many owners hosted "radio parties" and danced to the latest jazz music with their friends. At the same time, the game of Bridge was sweeping the country. Read how one card company used this "new technology" to promote their products.

AN ESP32 / TEENSY 3.5 SUPER CLOCK

 

After creating an Internet connected digital clock using the Adafruit RA8875 driving an seven inch LCD display, I decided to step it up a notch and add several additional features including: the ability to set an alarm; a countdown timer for uses like monitoring an exercise program; a weather display to provide brief conditions at 10 different cities; a real time stock market report that gives the changing prices for a selection of stocks; and lastly (just for fun), a Mandelbrot fractal generator to produce those wonderful images.

 
 

WAITING FOR 5G WIRELESS

 

By now, you've certainly heard of the forthcoming fifth generation (5G) wireless technology. There's a tremendous amount of hype about 5G as the various cellular operators try to pre-sell you on the new benefits and services. Commercial 5G services won't go online until later this year, but we should see plenty of 5G action in 2020. For that reason, you'll need to know more about 5G to understand what impact it will make on you and the world in general. Here's a status report to bring you up to speed.
