The invention of the phonograph happened quite by accident. Thomas Edison moved to Menlo Park, New Jersy in 1876, where he established an industrial research laboratory. There, Edison was working on a carbon telephone transmitter to improve the existing Bell telephone system. In that laboratory a year later, Edison invented the phonograph while he was trying to improve a telegraph repeater. He attached a telephone diaphragm to the needle in the telegraph repeater; in this way, he was able to reproduce a recording that could be played back. After he made some improvements to the machine, he tested it. He recited “Mary Had a Little Lamb” into the machine and played his voice back to a very surprised audience.

The Fitbit Flex is a mobile device aimed at measuring your exercise, diet, and sleep. It's very easy to wear it all the time. It is very light and comfortable, and it looks casual and natural on your wrist. When I need to wear a watch, I have one that sits next to the Flex quite easily. You can get different Fitbit Flex wristbands, reasonably priced, in dozens of fun colors!

I was pleasantly surprised to learn how many steps I walk during my normal working day. I actually find ways to fit in even more activities at work, so I can watch the numbers go up. It's water-resistant, so I can wear it in the shower or in the rain without worrying about keeping it dry. The Fitbit synchronizes with my smartphone via Bluetooth.

Tracking food items makes it possible for the Dashboard to display a calorie budget for you, comparing calories consumed versus calories burned. It will use the daily calorie total you create to show you how many calories left in the day.

While I'm sleeping, the Fitbit Flex measures the movements of my wrist, logging my sleep as awake, restless, or asleep. It has been fascinating to see my sleep pattern each night and over time.

There is a notification alert to let me know when my battery is running low. After 10 minutes or so in the charging cable, it's good to go again. The Fitbit Flex battery needs charging every 3 to 5 days.
