New „hardwired“ TCP/IP chip from company Wiznet resists attacks, it´s fast and consumes only a minimum energy and host MCU resources. TCP/IP solutions from company Wiznet are known by its resistance resulting already from their principle . all the solution is hardware-based, thus it´s not possible to change a basic functionality of a device (flooding, […]

More than a year ago, a friend of mine asked me to write the software for his 3D Spectrum Analyser (3DSA): a device that takes as input an audio signal, and outputs its visualisation on a 3D matrix of leds. If the above description doesn’t quite ring a bell, simply watch the end result in

High power of the UDOO “asks” for usage. One of many occasions to make it is to use various available periphery thus gaining a truly universal platform. Favorite powerful embedded SBC called UDOO (S975-G000-2100-C2) already found many fans. Maybe also because of its compatibility with the Arduino Due platform (hardware and software) and mainly, it´s

The Yún is unique in the Arduino lineup, as it has a lightweight Linux distribution to complement the traditional microcontroller interface. It also has WiFi and Ethernet connections on board, enabling it to communicate with networks out of the box. The Yún’s Linux and Arduino processors communicate through the Bridge library, allowing Arduino sketches to
Let’s explore Arduino Yún’s unique features – Hardware review Read More »
As electronic products get smaller and better, so must the converters powering them. Besides delivering higher efficiency from a smaller footprint, these DC/DC converters must also respond rapidly to varying loads while making the system designers’ jobs simpler. Consequently, power supply makers continue to tap the benefits of advances in packaging, architecture, and semiconductor processes

Before I start I guess I must answer 2 questions which would be asked inevitably: 1) Why? Because I can. To learn how electronics behave at cryogenic temperatures. And just curios how much juice you can squeeze out of AVR if you push hard enough This also produced some results relevant to desktop processors overclocking

General Description The MIC826 is a low-current, ultra-small, voltage supervisor with manual reset input, watchdog timer, and active-high and active-low push-pull outputs. The reset outputs are asserted and held when the supply voltage falls below the factory-programmed threshold voltage, when the /MR pin is pulled low, or if the watchdog times out. Reset is asserted
