Description This is my second encounter with LM3886. I was pleased of the sound this chip produced the first time, so I decided to make another amplifier with it. The schematic is based on the schematic in the datasheet of the chip with minor changes. I removed the time delay capacitor connected to MUTE pin, […]

We’ve already seen artificial skin capable of sensing touch and prosthetics that sense texture, but now a group of Korean scientists has come up with a stretchable electronic skin that “feels” in three dimensions. The artificial skin is made from arrays of microscopic domes that interlock and deform when pressed. It can detect the intensity, […]

In this episode Shahriar compares the performance and features of the Siglent SDG5162 and Rigol DG4162 Arbitrary Waveform Generators. Siglent has recently opened a new North America office which would certainly help them bring their instruments to the US more quickly and provide better local customer and sale support. The Siglent SDG5000 teardown is presented. […]

MCUs are used as the main control element in just about every application imaginable. Their power and flexibility make them the go-to component at the heart of most designs. Since it is important to make sure that your design cannot be easily copied, reverse engineered or tampered with, modern MCUs now provide a few different […]

Enabling faster and higher volume data transfers than ever before, the FT60x is the first SuperSpeed USB3.0 series from FTDI Chip that offers USB access to a wider range of data intensive imaging and data acquisition applications. The series incorporates two devices – the FT600 and FT601, which function as SuperSpeed USB3.0 to FIFO bridges, […]

If your website goes down, you want to be the first to know. Make it obvious when there’s a problem by hooking up a big alarm light to a Tessel, which will ping your website every few seconds to check for trouble. Continuously off: all is well Continuously on: website being monitored is down Two-second […]

A logic analyzer is an excellent tool for capturing many digital signals at once and displaying their timing relationships. It is particularly useful in verifying and debugging digital circuits. This tutorial is intended to provide a quick overview of a logic analyzer tool and its uses in analyzing and decoding data flowing on multiple signal […]

Even a simple, well-designed tool can help significantly – we´ll introduce to you some of them … Sometimes, only a little bit is necessary to make our work more happy – a good ergonomic chair, workbench in a suitable height, good lighting … and last but not least also a good screwdriver, magnifying lens, tweezers, […]

Surya Mattu is a creative technologist who loves to make things. He’s based in NYC and working at ITP, a two-year graduate program exploring the imaginative use of communications technologies. Today he’s sharing with us how feasible it could be to build an RFID-controlled entry for students using Arduino Yún. Read  other guest posts on Arduino Yún. […]

The most popular RTC for the Arduino is the DS1307. However, it does have some drawbacks, the most notable of which is that its operating voltage is 5v, which means it cannot be used with 3.3v projects. The Maxim DS1339 however, features a wide tolerance of voltages from 2.97V-5.5V with the typical voltage as 3.3v, […]
