Electronics is relevant to our modern lives like almost no other field of science. On the one hand, we have the physical world, with objects and phenomena that we touch, see, and interact with. On the other, we increasingly spend time with the digital world, where we log data in spreadsheets or apps, solve complex problems with the help of computers, or rely on various devices to make our lives easier.
Sitting in between these two worlds and bridging the divide is electronics. Without it, there would be no microprocessors, no grids of tiny transistors to switch on and off and do our bidding millions of times per second. No way to power our homes or gadgets, or even manufacture many of the non-technical goods we take for granted. It has truly revolutionized every facet of our existence. Much emphasis today is placed on programming and application development, but it is important to remember that these things are abstractions sitting on top of a physical and electrical foundation.
In case all of this talk of revolution has you fired up, we’ve collected some of the best books to help you learn electronics. Whether you’re a total beginner or advanced engineer, check out the resources below to find a learning guide that’s right for you.
As the Arduino surges in popularity, people keep dreaming up crazier and more complex ways to use it. We’ve rounded up five of the most impressive Arduino projects on the web to show what’s possible with such a versatile and inexpensive platform. Be warned – these projects aren’t for beginners, but if you’re looking for a challenge and something to brag about, they could be just the ticket.
A new Kickstarter project aims to provide a low-cost, open source platform for building a GPS tracking device. The author, Wayne Truchsess of DSS Circuits, explains that a few years back, his brother in law had a PS3 stolen during a long power outage in the depths of winter. Not wanting to repeat history, Wayne bought a fake PS3 case on eBay and developed his own prototype position tracker to put inside it.
The tracker consists of a GSM cellular modem, a GPS unit, and an accelerometer, all tied to an Arduino and a LiPo battery to provide brains and power, respectively. Normally, the device lies in wait, asleep to save power. If it detects motion, it turns on the modem and alerts a preconfigured phone number via SMS. The owner can then respond with various commands to turn position tracking on or put the device back to sleep.
