Electronics designers can boost their productivity with free symbols & footprints for Samtec products Samtec is releasing new digital models for over 100,000 of its products on SnapEDA, the industry-leading circuit board design library. Traditionally, designers have spent days creating digital models – such as symbols and footprints – for each component in their designs. […]

Where won’t they put a TV these days? We’ve even seen one creeping behind semi-transparent mirror film in the ladies’ room of a sports bar, though that one didn’t last long. Up until that moment, we had never wished so hard for a TV-B-Gone, especially one as small and powerful as this DIY version by [Shane].
A team led by the Technical University of Munich (TUM) physicists Alexander Holleitner and Reinhard Kienberger has found success for the first time in generating ultrashort electric pulses on a chip. They made this possible by using asymmetric metal antennas only a few nanometers in dimension, then running the signals a few millimeters above the

For many kids, the tin-can telephone is a fun science experiment that doesn’t last much longer than it takes to tangle the string around a nearby tree. [Geoff] decided to go a different however, building a tin-can telephone that’s completely wireless. The build starts with a hacker favorite, the Arduino Uno. It’s hooked up to an

The Chinese based technology company Rigol Technologies has launched a new high-performance oscilloscope series, the MSO/DS7000 Oscilloscopes. This new series incorporates some of Rigol’s latest developed technologies and includes RIGOL’s self-developed ASIC chipset “Phoenix” into it. The introduction of the MSO/DS7000 series oscilloscope will make it the first time for a Chinese enterprise to launch its own developed
7-into-1 Oscilloscope features a 10.1″ touch-color display Continue Reading
I recently finished the installation Equally diverse, which is made of a series of lamps that react to the sensors placed in a rug underneath the lamps.Here is how I made the rug with pressure sensors.I hope you will find it useful. 🙂 Step 1: How to Make the Sensors For the pressure sensors, I

Today I will share following topics base on a bicolor matrix led 32×32: D.I.Y a bicolor led matrix 32×32. How to control led board above with NodeMCU ESP8266 via B.A.M method. Introduce and share my code for some cool real time clock projects with this bicolor led board. Let’s start with some videos: Rainbow letters
If your project calls for light sensitivity, it’s hard to beat light dependent resistors (LDRs), also known as photoresistors. They’re available for a few cents each, and their resistance varies based on how much light they receive. In the dark, these devices produce resistances in the megohm range, and can fall to hundreds of ohms
Use a Comparator or Op-Amp to Simplify Light Dependent Resistor Output Continue Reading
Buried deep within all UNIX-based operating systems are vestiges of the earliest days of computing, when “hardware” more often than not meant actual mechanical devices with cams and levers and pulleys and grease. But just because UNIX, and by extension Linux, once supported mechanical terminals doesn’t mean that getting a teletype from the 1930s to work
