Here's an alarm clock that clicks on your favorite music, vibrates your pillow, removes your sheets and makes your coffee. Brian Wagner and his mechanical engineering teammates at Colorado State University (Matthew Cuff, Ryan Seeboth and Steve Schmitt) devised the perfect wake-up machine. The alarm uses a keypad and six LEDs to indicate depressed buttons or command functions that determine the sensory mix to wake you up and ease you into your day. The temperature gauge can be connected to a heater or fan to activate the perfect wake-up temperature.
Using three (four?) PICs, a keyboard encoder, a 555, and four digital potentiometers when only the PIC16F747 would do is not a good design. I suspect everything on the "Light Dimmer Circuit" sheet could also be incorporated into the one PIC16F747.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
