Researchers at Cambridge University have just achieved a spectacular breakthrough in electronics design. They have developed new ultralow power transistors that could function for months or even years without a battery. These transistors look for energy from the environment around, thus reducing the amount of power used. Dr Sungsik Lee, one of the researchers at […]

Last time you learned how to connect the ESP8266 to a WiFi network and download data from a URL. Today we will explore a way to listen to connections just like a server; a web server in fact. The ESP will listen for connections on port 80 and will serve simple pages to connected clients. […]

PragmatIC is a world leader in manufacturing ultra low cost flexible electronics enabling the potential for trillions of “smart objects” that can interact with their environment. It has developed a unique platform of patented technologies to design and manufacture flexible integrated circuits (flexICs), also known as “printed logic”. These flexICs deliver intelligent electronics without the […]

E-paper in Your Next Project Do you have a great idea that needs a screen which requires zero power to maintain an image? Are you looking to add an interesting display to your next project? Want to prototype a low-cost, persistent screen that can be read in direct sunlight? You may have seen E-paper in […]

Description The MAX30205 temperature sensor accurately measures temperature and provide an overtemperature alarm/interrupt/shutdown output. This device converts the temperature measurements to digital form using a high-resolution, sigma-delta, analog-to-digital converter (ADC). Accuracy meets clinical thermometry specification of the ASTM E1112 when soldered on the final PCB. Communication is through an I2C-compatible 2-wire serial interface. The I2C […]

Making LED displays and signage is a complete industry in itself serving all sorts of clients like banks, railway stations, factories, airport and more. In earlier days display units were made using individual LEDs carefully placed and soldered to make matrix of display. But this task was very mundane and slight misplacement of LED gave […]

Connecting Bluetooth Module with Development Board The Bluetooth module has seven interface pins of which two are NC (not connected) pins. The table below shows how you can interface with it our low cost AVR development board. Bluetooth Module Dev Board GND GND RST PD2 TX PD0 RX PD1 NC NC +5V IN VCC Connecting […]

A new prototype of a lithium-sulphur battery – which could have five times the energy density of a typical lithium-ion battery – overcomes one of the key hurdles preventing their commercial development by mimicking the structure of the cells which allow us to absorb nutrients. This gets us a long way through the bottleneck which […]

You can call up on your colleague‘s mobile number and ask him/her to turn on or off the lights or other appliance of your office. You may be any where in the world at that time, as mobile network allows to to talk to anyone present anywhere in this world. But your colleague is too […]

Last Thursday I had a lot of fun doing a workshop at my college (UMass Amherst) where I taught students to use a WiFi-enabled Color LED matrix combined with Javascript programs to create animations displayed onto the LED matrix. The matrix is made of 5×7 WS2812 (NeoPixel) LEDs. I’ve actually designed it two years ago […]
