Eye Diagram Basics: Reading and applying eye diagrams
https://www.electronics-lab.com/eye-diagram-basics-reading-and-applying-eye-diagrams/
Deepak Behera, Sumit Varshney, Sunaina Srivastava, and Swapnil Tiwari discuss about using an oscilloscope to create eye diagrams and quickly evaluate system performance and gain. Accelerating data rates, greater design complexity, standards requirements, and shorter cycle times put greater demand on design engineers to debug complex signal integrity issues as early as possible. Because today’s serial […]
Passive Wi-Fi – Bringing Low Power to Wi-Fi Transmissions
https://www.electronics-lab.com/passive-wi-fi-bringing-low-power-to-wi-fi-transmissions/
Bryce Kellogg, Vamsi Talla, Shyam Gollakota, Joshua R. Smith have published an research article discussing Passive Wi-Fi transmission that consumes 3 – 4 orders of magnitude lower power than existing Wi-Fi chipsets. Passive Wi-Fi transmissions can be decoded on any Wi-Fi device including routers, mobile phones and tablets. Building on this, we also present a […]
Controlling Arduino using your Voice
https://www.electronics-lab.com/controlling-arduino-by-voice/
bluehybrid @ instructables.com shows us how to use your voice to control a led light on Arduino. To achieve this he used the 1Sheeld Arduino shield. This Project is getting start to use arduino with 1Sheeld In this project we will turn an LED (ON) and turn it (OFF) by Voice We will say “Open” to turn […]
Portable Adjustable Mini Power supply
https://www.electronics-lab.com/portable-adjustable-mini-power-supply/
Mixed Output @ instructables.com has build a nice power supply by combining different power modules. As most of my project involve electronics of some sort, having a good power supply is essential to be able to meet the demand of different power requirements. So I built me a bench-top power supply from an old ATX power […]
Teardown: Amazon Dash Button keeps you connected
https://www.electronics-lab.com/teardown-amazon-dash-button-keeps-you-connected/
Brian Dipert @ edn.com has done a teardown on Amazon’s dash button and shows the parts inside. How much hardware was Amazon able to squeeze into such a diminutive bill-of-materials budget, or perhaps more accurately, how much are Amazon and its consumable-supplier partners subsidizing the initial hardware cost in the hope of plenty of future generated […]
Sensirion Tiny sensor hones temperature accuracy
https://www.electronics-lab.com/sensirion-tiny-sensor-hones-temperature-accuracy/
Housed in a tiny 8-pin DFN package, the STS31 digital temperature sensor from Sensirion guarantees accuracy to within ±0.3°C over a temperature range of -40°C to +90°C. A low-cost version, the STS30 achieves the same accuracy over a temperature range of 0°C to +65°C. Both devices are only 0.9 mm high and occupy a footprint […]
Hardware serial port monitor over WiFi
https://www.electronics-lab.com/hardware-serial-port-monitor-with-wifi/
This tutorial shows how to connect Arduino to the TX line (of a router, RPI) and display serial data on smartphone over WiFi. Arduino listens for serial port communication on its hardware serial port. Then it sends every received line of data trough software serial port to ESP8266. ESP8266 puts every received line of data […]
DIY Wearable Posture Sensor
https://www.electronics-lab.com/diy-wearable-posture-sensor/
With the help of this wearable device you can improve your posture as it will remind you whenever you slouch. The device is based on ADXL335 accelerometer and Attiny85 microcontroller and a vibration motor will get you notified. Posture sensors/monitors have been a recurring theme on this blog. They are supposed to remind you of your posture […]
Wifi Home Thermostat
https://www.electronics-lab.com/web-enabled-home-thermostat/
asheville makers @ instructables.com has posted a Wifi enabled thermostat that can be programmed via a touch screen display or via the internet. This Instructable explains about how I built WiFi enabled thermostats for my home. The thermostats are programmable with 6 different time periods during the day, although increasing that to any arbitrary number would […]
4A Bipolar Stepper Motor Driver Based on LV8727E
https://www.electronics-lab.com/4a-bipolar-stepper-motor-driver-based-on-lv8727e/
The Project is based on LV8727E IC from ON Semiconductor. The LV8727 is a PWM current-controlled micro step bipolar stepping motor driver. This driver can provide eight ways of micro step resolution of 1/2, 1/8, 1/16, 1/32, 1/64, 1/128, 1/10, 1/20, and can drive simply by the step input. This Bipolar Driver works with supply […]
