The future of 3D printing is here and it has a name – Wembi. Boasting an advanced PID compensation system that detects issues while your 3D printer or other CNC based machine is moving, Wembi readjusts itself to eliminate printing problems and help you get the perfect prints...

REC Johnson, B Lora Narayana, and Devender Sundi share their design idea on how to use a transistor as a heating element. It is common to use transistors for driving resistive heating elements. However, you can use the heat that a power transistor dissipates to advantage in several...

This is a general purpose relay board accepting 8 inputs to drive 8 relays providing control requirement in your project. This board can also be used as an add-on card for the various Development board that we provide and various microcontroller boards. Features Robust Design...

nick @ novemberfive.co tears-down the Withings GO activity tracker. First, we removed the battery. This is easy: you can simply open the back of the casing with the included tool or with a regular coin. The included battery turned out to be a Panasonic 3V CR2032 with a capacity of...

Scott from SWHarden has published a new build: Today I made a high frequency multiplier using a single component: the ICS501 PLL clock multiplier IC. This chip provides 2x, 5x, 8x (and more) clock multiplication using an internal phased-lock loop (PLL). At less than a dollar on eBay,...

By Bonnie C. Baker (WEBENCH® Senior Applications Engineer): Numerous filter approximations, such as Butterworth, Bessel, and Chebyshev, are available in popular filter software applications; however, it can be time consuming to select the right option for your system. So how do...

Solid-state relays introduction from Vishay, (PDF) MOSFET SSRs feature an optocoupler construction, but have a pair of MOSFETs on the output instead of a phototransistor. A pair of source-coupled MOSFETs emulate an electromechanical relay by providing bidirectional switch capability...

James O'Neill explores a Transcend SD that he believes it's the smaller Linux server. It's actually a 16GB memory card, an ARM processor and a WIFI chip all in an SD card package. The way these cards works is different from the better known Eye-FI card. They are SERVERS : they...
