A breadboard Arduino will require an Atmega328P controller for these instructions. Note the “P” at the end of the name. You cannot use an Atmega328 because it has a slightly different device id number. It will require a different board configuration. Instructions for that are outside of this tutorial. Go to the Arduino tutorial website […]

Embedded systems frequently use HD44780-type LCD displays as it is considered the most popular alphanumeric display controller. The interface comprises at least 14 pins: eight for data, three for control (EN, WR, RS), two for power supply (Vdd, Vss), and one for contrast (Vre). Configured in 8-bit mode, it requires at least 10 I/O lines […]

Using new, high-resolution global satellite maps of air quality indicators, NASA scientists tracked air pollution trends over the last decade in various regions and 195 cities around the globe. The findings were presented Monday at the American Geophysical Union meeting in San Francisco and published in the Journal of Geophysical Research.

Los Alamos National Laboratory’s portable MRI was named one of the Top 10 Breakthroughs of the Year by Physics World, the member magazine of the Institute of Physics. Portable MRI, also called Battlefield MRI (bMRI), uses ultra-low-field magnetic resonance imaging to create images of injured soft tissues, such as the brain.

Louisiana State University paleoclimatologist Kristine DeLong contributed to an international research breakthrough that sheds new light on how the tilt of the Earth affects the world’s heaviest rainbelt. DeLong analyzed data from the past 282,000 years that shows, for the first time, a connection between the Earth’s tilt called obliquity that shifts every 41,000 years, and the movement of a low pressure band of clouds that is the Earth’s largest source of heat and moisture—the Intertropical Convergence Zone, or ITCZ.

As the use of soilless, hydroponic growing methods becomes more prevalent among crop producers, researchers are looking for new materials that can help growers save money, produce healthy plants, and contribute to sustainable practices. The authors of a study in the October 2015 issue of HortScience say that biochar, a charcoal-like material produced by heating biomass in the absence of oxygen, can help “close the loop” when used as a substrate for soilless, hydroponic tomato production.

This is reflow soldering controller for use with a toaster oven as reflow soldering oven. I bought the toaster oven in a local super market for about 40 €. There was also a cheaper oven on sale, but I wasn’t sure if it did 250°C, so I bought the more expensive and prettier one. Since […]

video Playing video on nokia color LCD using an ATmega32 Hi, I am introducing my new video player made using an atmega32 microcontroller and nokia color LCD. I got a 65K color LCD from an old nokia 6030 mobile phone.  I directly soldered 10 thin enamelled coper wire from the 0.5 cm square area of […]

For a project of mine, I need to flash several hundred of ATMegas. I use a special programming connector, which sits on the SMD chip and connects directly to the ISP and power pins on the chip. My first attempt to ease the flashing process was to mount the programming connector to a lever with some additional […]

A time has come for me to say ‘hello’ to the mid-XX century technology of  Neon numerical displays, also known as Nixie tubes. Despite being quite hard to obtain and utilize I’ve decided to make a nice looking clock which (hopefully) would make a perfect Christmas present, and since the Christmas is all about sharing I thought It would […]
