Tisham Dhar designed an ATM90E26 energy meter breakout board which can be used in single phase power measurements. After designing and testing the ADE7763 based Energy Monitor Breakout Board, I started looking around for cheaper and more modern alternatives.I came across the Atmel...

Ken Shirriff reverse engineer the CMOS version of 555 timer IC and explains how it works. This article explains how the LMC555 timer chip works, from the tiny transistors and resistors on the silicon chip, to the functional units such as comparators and current mirrors that make it...

Clemens Valens @ elektormagazine.com shows us a new IC Package that keeps the IC cool. Texas Instruments’ HotRod QFN is a thermally enhanced plastic package with solder lands on all sides as well as power buses for enhanced current carrying capability. Inside the package the die...

LG Innotek has released an ultra-thin optical biometric sensor module designed to be used in wearables and smartphones to measure health parameters such as heartbeat, stress indicators and blood oxygen saturation level. The new sensor is more accurate than it's predecessors...

Ken Shirriff has done a detailed teardown of the popular 555 timer IC. Let's take a look inside this little chip: Given the popularity of the 555 timer, I thought it would be interesting to find out what’s inside the 555 timer and how it works. While the 555 timer is usually sold...

Andreas Olofsson @ parallella.org has compiled a long list of acronyms used in the chip industry. If you would like to be an expert on IC field, take your time and check it out. Given how important chips are to modern society EVERYONE should understand and appreciate how they are...

Researchers at MIT has announced a new RFID chip that is almost impossible to hack and it could mean that an identity thief couldn’t steal your credit card number by sitting next to you. The researchers’ new chip uses a bank of 3.3-volt capacitors as an on-chip energy source. But...
