Programming microcontrollers isn’t hard. Building a programmer makes a great first electronics project. The goal of this instruct able is to explain the simple ‘in circuit serial programming’ method used with Microchip PICs. Programming a big DIP (through hole) chip is easy. Pop it into a socketed programmer, burn, and return to the application circuit. […]

I had the fortune to visit CERN (European Council for Nuclear Research) earlier this month. Located on the Franco-Swiss border, CERN is home to the most powerful particle accelerator mankind has ever built, the Large Hadron Collider, otherwise known as the LHC. Here, bunches of approximately 100 billion protons each are accelerated in opposing directions

I’ve started to build a little FM radio with one of this cheap modules with a Phillip chip, the TEA5767. I will control it with a MSP430, probably I’ll use some kind of encoder to change stations and a potentiometer for the volume. The TEA5767 is a single-chip electronically tuned FM stereo radio for low-voltage applications

Poe – Power over Ethernet is already a common is already a common matter. With the Ag5200 module you too can use this functionality and eliminate a mains adapter. A thought to use an Ethernet cable even for a power supply is already known for many years. To use an existing data connection even for an

After a year or so of reading and drooling over other people’s wonderful projects in these pages I decided to finally make one of my own. Here is my first instruct able, a version of the ever popular Battery Desulfator, which I built in an Alto IDs tin. First, some background: My urge to build

Sleep modes and idle modes in general-purpose microcontrollers have allowed embedded processors to reduce real-time energy consumption and tackle many battery- and low-powered designs. However, as embedded systems become increasingly complex, it takes additional logic to implement a denser, more sophisticated micro core as well as the higher-end peripherals we expect to see today. As

After making a 8X10 matrix a lot of people asked me about expanding the matrix to some thing bigger, and some wanted to write stuff to the matrix via a PC, so one day I looked at a pile of LEDs that I had leftover from a LED cube projected and I decided to make

I wanted to make an easy and secure way to enter my garage. RFID was the best way to unlock my door, even with my hands full I can unlock the door and push it open! I built a simple circuit with a basic AT Mega 168 arduino chip and a ID-20 RFID reader to

Teledyne LeCroy demonstrated the world’s first 100 GHz real-time oscilloscope on July 24, 2013 at the research facilities of Teledyne Scientific Company in Thousand Oaks, CA. In the demonstration, the prototype scope successfully acquired and displayed live signals at 100 GHz bandwidth. In addition, the Teledyne LeCroy and Teledyne Scientific also unveiled an indium phosphide
