Control a High Power 4W COB LED with Arduino Uno


https://www.electronics-lab.com/control-a-high-power-4w-cob-led-with-arduino-uno/

educ8s.tv has published a new Arduino Video tutorial: High Power LEDs are very popular and low cost nowadays so I thought it would be a good idea to learn how control them with Arduino. So, I built a simple project that simply turns on a 4W Cob LED when the button is pressed. When the […]

The incredible story behind the Gerber PCB file format


https://www.electronics-lab.com/the-incredible-story-behind-the-gerber-pcb-file-format/

Max Maxfield @ edn.com writes about the famous Gerber format and the history behind it. Gerber format is actually an ASCII vector format that defines copper layers, solder mask, legends on a PCB and it’s used by manufacturing companies to produce the actual PCB. The incredible story behind the Gerber PCB file format – [Link]

Raspberry Pi 2 Web Hosting – Full Email Server & Web Server


https://www.electronics-lab.com/raspberry-pi-2-web-hosting-full-email-server-web-server/

LDSrelience shared this video on Youtube! This is a short video going over a project I just finished to prove that a Raspberry Pi 2 Model B (new as of February 2015) can run a light duty website and low volume email server. I have installed Apache2 for the web server, which takes like 2 […]

https://www.electronics-lab.com/sk6812-a-new-intelligent-rgb-led/

Tim discuss about a new RGB LED that appeared on the market: During the last months, a new WS2812 alternative appeared on the market: The SK6812. I finally managed to get my hands on some of them to take a closer look. In most aspects these devices are basically clones of the WS2812. What is […]

5V @3A Switching Power Supply


https://www.electronics-lab.com/project/5v-3a-switching-power-supply/

This circuit is about a buck regulator which can produce an output of 5V for a input voltage ranging from 7V to 40V. LM2576 is a monolithic IC and it acts as the heart of this circuit. This IC has a potential of delivering an output current up to 3A and requires less number of […]

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 […]
