Under a microscope, a silicon chip is a mysterious world with puzzling shapes and meandering lines zigzagging around, as in the magnified image of a 7805 voltage regulator below. But if you study the chip closely, you can identify the transistors, resistors, diodes, and capacitors that make it work and even understand how these components […]

Choosing components is a series of time-consuming tasks, from surveying the market for possible candidates to properly evaluating performance. As a hardware engineer who has worked in Silicon Valley for 10 years, I have spent significant time developing test plans and specs, building fixtures, and testing components. One of the reasons comparing components takes a

If you need to simulate overvoltage, slow start, fluctuations and other situations, which may occur in real life, then the TDK Lambda power supplies won´t disappoint you. Imagine a laboratory (testing) power supply able to provide a virtually any function. Switching on, drop-out, repeated switch-on and many other functions, by which we can test our

Description The circuit is built around a popular Sanyos stereo head preamp IC LA3161. Low electrical signals from the playback heads are fed to pins 1 and 8 of IC1 via DC decoupling capacitors, respectively. Components between pins 2 and 3 and pins 6 and 7 provide adequate equalization to the signals for a normal

What’s an Apple Watch good for? How about unlocking doors with just a tap on an app? We figured out how do something no one else has done for under 150 bucks, using standard door-strike hardware, our custom app, and a tiny RFduino microcontroller. In this Weekend Project we’ll show you exactly how to do

Description A countdown timer with super bright 7-segment displays that flash when the time is up, instead (or in addition to) an audible alarm. The design is based on a PIC16F886 microcontroller which drives the displays using a TLC5916 LED driver and dual P-channel MOSFETs. A rotary encoder with a push button is used for
