In this era of instant gratification, an emergency pizza button ranks somewhere between the invention of sliced bread and the printing press.
So, which PWM technique is best for your motor control application? In case you haven’t guessed, this is somewhat of a trick question. It’s kind of like asking “which ice-cream flavor is the best”, since everybody knows that the answer is obviously “chocolate chip.”
A while back I wrote up how to make A Perfect Divider which divides a voltage by 10, 100, 1,000 etc. using mostly very common resistors (100K, 10K, 1K etc.) with only two uncommon resistors to make a resistance divider that divides by decade increments.
Tinker’s Toolbox returns to the data center with Jeff Klaus, Director of Data Center Solutions at Intel. Workload, power consumption, thermal management and energy efficiency are always concerns in the data center, and Jeff will
IDTechEx forecasts the touch screen market to reach $14 billion in 2012. The biggest application for touch screens in general, and projected capacitive screens in particular, is mobile phones and, right behind, tablets.
A conclusion at the start of a report and the active voice improve engineers' written communications.
The other day, I received a press release from a company that announced plans to apply its technology to the automotive space. The memo cited research from Strategic Analytics which predicts a 10 percent compound annual growth rate in the market for the next five years.
David Jones has a very good video up on YouTube about how to go from a working prototype to high volume manufacture. The video is a bit over 50 minutes long so be prepared to put some time in. The information is oriented to the novice...
GreenArrays, a company I have written about extensively is opening an on line institute for those who want to learn more about how to program and use their chips. They call it the Array Forth Institute. First time log-in is fast and simple.
Working hard to catch up to the rest of the world, the European Commission's Unmanned Aircraft Systems Panel began meetings February 9 in Brussels, Belgium, to agree on the key flight rules and technologies for commercial UAVs
Electronic bone healing technology has been around for a while but has increased in popularity as electronics technology enables increased functionality in significantly smaller form factors. The need to integrate advanced functionality into a small device also creates
This blog is for all you control engineers up there in the New England area. The TI Industrial Control training event is coming to Boston on Tuesday, March 27th through Thursday, March 29th. We did this about a month ago in Chicago...
Atmel Corporation announced 14 new devices in its AVR microcontroller (MCU) family, providing more options to meet unique design requirements. Used by well over 100,000 engineers worldwide, AVR microcontrollers are regarded for their performance, power efficiency and flexibility across many application areas. Adding more memory, connectivity peripherals and system integration, the newest devices
I was hanging out at the FreePCB blog where commenter gnuarm suggested DorkbotPDX for production of hobby boards. The production process is not hobby grade. You get a solder mask on both sides, silk screen (legend), and a 6/6 process.
Joseph Citrano of Honeywell Sensing and Control (S&C) is my guest for this edition of Tinker’s Toolbox. As wireless technology gains widespread adoption on the factory floor, concerns about
Did you know that your hydraulic steering system wastes more energy than any other system in your car and is third highest in total vehicular energy losses (right behind wind resistance and road resistance)?
In my search for good tools that don't cost too much (I like free) I have found an excellent tool for viewing Gerber and drill files. Those are the files produced by most PC board design software and required by most board producers to produce boards.
We here at SparkFun have been known to use our products to play pranks on each other from time to time, and we're always on the lookout for ways to make life at the office more Fun.
The Bright Bunny Kit is a great way to learn soldering and hand sewing. At the end of this project, you'll have a cute stuffed animal that lights up when you feed it a carrot! The original design for the Bright Bunny came from Phillip Lindsay, aka follower.
Sometime around mid 2011, Sparkfun had the idea of holding an Open House as a fun event that would give us the opportunity to interact with the community. We brainstormed many fun ideas for the event and decided on which ones to shoot for.
Microchip Technology Inc. announced a new family of 8-bit microcontrollers (MCUs) featuring next-generation analog and digital peripherals, making them desirable for general-purpose applications, as well as
How cool would it be if you turn any button, joystick, sensor, or other electronic gizmo into a USB keyboard and/or mouse? You could make just about any input device you want into a controller for your computer programs or games.
We're always looking for more ways to make our office fun and strange. One of our engineers, Mike, recently rigged up the elevator to play the Tardis noise. I wanted to do something similar, but, specifically, in my office.
Terminology used to describe the color quality of an LED light source is often reduced to three letters: CCT and CRI, which are probably the most familiar, and CQS and GAI, which are relatively new. What do these abbreviations stand for, and how are they used?
Many engineers see engineering and writing as mutually exclusive skills. They think people can do one or the other, but not both. Engineers can write well, although it takes some practice.
