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...

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....

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...

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...

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...

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...

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...

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...
