Fifty cents goes much farther than it used to in the 8-bit microcontroller market. Microchip is selling the PIC16C505 one-time-programmable (OTP) part for 49 cents, and the PIC16CR54C ROM device for 40 cents. The 14-pin parts provide an upward migration path to increased I/O capability for designs based on the company's 8-pin controllers. The OTP part sports 1,024312 words of program memory, 72 x 8 bytes of user RAM, 12 I/O pins, and a 4-MHz internal clock oscillator. The ROM version offers 512 x 12 words of ROM program memory, 25 bytes of user RAM, and 12 I/O pins. Both operate from 2.5 to 5.5V, use 33 single-word instructions, and offer a full-speed 200-nsec instruction cycle at 20 MHz. Microchip Technology: Product Code 4277
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.
