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.
“Hello, hello. I am calling from a battery-free phone.” Vamsi Talla’s words in a cluttered lab at the University of Washington in Seattle are barely audible through pops and static. But the fact they can be heard at all, on a nearby Android smartphone, is revolutionary, because Talla’s own cell phone has no battery at all.

I worked on creating a Internet connected worked on creating a Internet connected last week using my open source WiFi relay project as platform. We observe quite dry air at our house, I suspect this is due to the fact that we use fan coils for heating/cooling. Humidity levels at home are usually below the 30% mark, which poses a health
Development boards are assistant tools that help engineers and enthusiasts to become familiarized with hardware development. They simplify the process of controlling and programming hardware, such as microcontrollers and microprocessors. Electronut Labs, an embedded systems consulting company, had produced its new BLE development board “Bluey” with a set of useful sensors and NFC support. Bluey is an open
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

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. Finger pricking, the

Renesas Electronics Corporation announced the successful development of a new low-power SRAM circuit technology that achieves a record ultra-low power consumption of 13.7 nW/Mbit in standby mode. The prototype SRAM also achieves a high-speed readout time of 1.8 ns during active operation. Renesas Electronics applied its 65nm node silicon on thin buried oxide (SOTB) process to develop this

What is it? This is a small (17.9 mm x 10.3 mm) breakout board with Bosch’s BME280 pressure, temperature, and humidity sensor as well as AMS’ CCS811 digital gas sensor. The sensors work in concert to provide a complete measurement via I2C register reads of indoor air quality including temperature- and humidity-compensated estimates of equivalent
