How to Route Differential Pairs in Autodesk EAGLE If you’re designing a high speed PCB, then chances are you’re working with the latest and most powerful technologies, like HDMI, USB3.0, Ethernet, or DDR. But with great power comes great responsibility! As a result, you’ll likely be dealing with issues like electromagnetic interference (EMI) and noise. […]

DC motor converts electrical energy in the form of Direct Current into mechanical energy. In case of motor, the mechanical energy produced is in the form of rotational movement of the motor shaft. The direction of rotation of the shaft of the motor can be reversed by reversing the direction of Direct Current through the […]

Keysight Technologies’ E36300 series of bench power supplies provide three outputs with power of 80 W or 160 W with line/load regulation of 0.01%. Front-panel buttons let you turn any output on or off and you can configure each output with 2-wire local sensing or 4-wire remote sensing. The 4-wire sensing removes losses caused by […]

Description This project aims to build a thin, flexible smartwatch. It’s wrap-around display and touchscreen will allow it to display more data at a glance than current devices. Besides telling time and displaying notifications, the watch will feature pulse rate, blood oxygen, and step sensors for health monitoring. Details Planned Features 180mm x 32mm x […]

Now that the mechanical assembly part is over,and we have completed the construction of left and right (L&R) infrared sensor cards. Since the MCU (ATmega8) cannot drive the dc motors directly, a dedicated motor driver circuit is used. The motor driver circuit here is based on a simple 16-pin IC (L293D) which can drive two […]

Mosquitoes are some of the most adept bloodsuckers on Earth. With a quick jab, sharp mouthparts plunge into human skin in search of a juicy blood vessel. It’s no surprise, then, that bioengineers have used the pest as inspiration for a device to periodically and independently sample the blood of individuals with diabetes. Fingerpricking, the most common […]

Before you search for specific MPNs, it’s useful to understand broad trends in electronic component pricing and availability to save time and money. At Octopart, we manage information of more than 40 million electronic parts, so we are uniquely positioned to aggregate the part data information and find interesting pricing trends. Electronic data is complex […]

Introduction In 2002 I wrote a linuxfocus.org article about a Microcontroller based DC powersupply (LF November2002 article251) The article received a lot of interest as I noticed from emails which I received on this subject. The design of this powersupply was however something for advanced hobby electronic fans due to the complexity of the circuit. […]

The 3D printing community is growing and innovating each day. Printers are becoming better and better, with higher print speeds, new features and capabilities. It is now time for the 3D printers’ counterpart, the filament extruder, to join the race. Introducing the DNA Extruder, a never-before-seen combination of speed, precision, quality and aesthetics. An entirely […]

In a recently published study, a team of researchers at SUNY Polytechnic Institute in Albany, New York, has suggested that combining multiple functions in a single semiconductor device can significantly improve device’s functionality and efficiency. Nowadays, the semiconductor industry is striving to scale down the device dimensions in order to fit more transistors onto a computer […]
