sweet dreams are made of this

By WILLIAM L. HAMILTONOCT. 2, 1997WE couldn't do much about the neighborhood's new motorcycle club. So we did something about the mattress.My back and I live together in a one bed room apartment. As we've gotten older, sleep has become a problem. How to get a good night's sleep?''Don't pay your bills and then hop into bed,'' said Dr. Daniel Wagner, the medical director of the Sleep-Wake Disorder Center at New York Hospital-Cornell Medical Center. Good advice; I intend to take it. But my back wanted facts it could act upon. ''Consider your bed carefully,'' said Dr. Gary Zammit, the director of the Sleep Disorders Institute at St. Luke's-Roosevelt Hospital Center in New York. ''It amazes me when I go in a bedding store and see how people select a bed. This is a place where you're going to spend a third of your life.''AdvertisementIt should have been obvious from the start. A mattress is going to be your worst e...

Why you need a digital business card app for business

Image
Paper business cards have been around for four centuries (since the 17th century). It has survived for such a long time and is still relevant today. Many businesses are still using it for the exchange of their organization or business contact information. But it's time to transform to the digital business card. Paper business cards are great and have withstood the test of time because they're cheap and have a meaningful purpose for every business – being a convenient way to share business contact information. A business card legitimizes who you are, conveys the services you offer, and provides a means for customers and business partners to remember you after a first meeting while providing contact information. With its legacy in connecting your business with prospective customers and partners, a paper business card has both the advantages and park disadvantages. Before we enter into the digital way of connecting people with business cards, let's have a strong understandi...

iot: raspberry pi robot with video streamer and pan/tilt camera remote control over internet

Image
This Instructable was one of the winners of 2016 AUTOMATION Contest. Thanks a lot for all votes! ;-)This is a second part of my previous Intructable: IoT - Controlling a Raspberry Pi Robot over internet with HTML and shell scripts only. There you learn how to control DC motors over the internet. Here we will learn how to streaming video using a PiCam and also remote controlling its position (Pan/Tilt), using servo motors. Controlling a camera over the internet slides can have several utilities, including for security use. As a particular example, we will install the camera and servos at the robot developed on the first part of the project. The video bellow will give you an idea about how the final project looks like:The block diagram shows the idea of the project. The RPi will be set as a WebServer and will receive commands from an HTML page. Those commands will control the GPIOs, making the RPi position the PiCam via the servo motors (Pan/Horizontal and Tilt/Vertical position). We ...

The best frying pans you can buy, from cast iron to non-stick and stainless steel

Image
T o find the best frying pans on the market, weasked chefs, food writers, and cookware professionals for their thoughts, and then put the standout itemsto the test in The Telegraph kitchen. After consulting with the experts, we decided that the pan we're looking for is versatile – it can cook different types of food to good effect – durable – it won't end up in the bin after three months – and good value for money – meaning it's either pleasingly affordable or so long-lasting that you won't ever have to buy the item again. There are a lot of different types of frying pan out there, so we narrowed our search to three main fields: iron pans (highly durable but harder to maintain), non-stick pans (easy to maintain but less durable) and stainless steel (highly spoken of by the pros but tricky to use). Each frying pan was tested for a variety of regular functions: frying or scrambling eggs, searing steaks, sautéing vegetables. We also considered: weight,ease of use,amount ...
