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, […]

This is an Instructable showing you how to integrate Twitter in your embedded application. Watch this Instructable in Action http://www.instructables.com/id/PIC-KICK-TWEET-1/ Working: A desktop application is created with ease for grabbing the latest tweet from your twitter account. The application then forwards the tweet to the serial port to which the embedded device is connected. A firmware […]

Put together a Arduino-based dust sensor over the weekend using the following components: Arduino Mega 2560 Shinyei PPD42NS dust sensor LCD Shield (16 x 2) The codes and wiring instructions for Arduino Mega 2560 and Shinyei PPD42NS is as follow. However, I did include Serial output so you can view the sampling results using Arduino […]

The huge increase of portable devices during the last 10-15 years has lead to numerous companies seeking (and succeeding) to make significant profits in this market. Many consumer applications are now powered by accumulators, ranging from the omnipresent cellular phones to media players, handheld gaming devices, and navigation systems (that is to name only a […]

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, […]

iButtons are small button like casings that communicate with only 2 wires. They are incredibly robust and all have a unique serial number which is hardware written into the device and never repeated. They are cheap (about 1 Pound / 1,50 Euro/ $2) This serial number allows the keys to be truly unique and thus […]

he TSR1SM series models of step-down switching regulators (non isolating – POL) have a high efficiency up to 96 % which allows full load operation up to +65°C ambient temperature without the need of any heat transmission layer. Excellent output voltage accuracy (±2%) and low standby current (~1 μA) are features that distinguish these switching […]

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 […]

The “Mädchen Machen Technik” workshop is designed to give high school students an introduction to microcontrollers. The students will build a flashing light pattern and/or a counter-timer. In the process of building this project, the students will learn about microcontrollers and digital electronics. Here is the parts list for the projects. Introduction to some circuit […]
