Chemical Wireless Communication Without Electronics
Posted on: 26 Dec 2017
Researchers at Stanford University have just invented a revolutionary way of communication. They are replacing the conventional way of wiring, wireless, radio and Bluetooth connectivity using chemicals that can be found in every house. Nariman Farsad, now a postdoctoral fellow at Stanford, had built the first ever experimental chemical texting system in York University, which […]
Atmel ATtiny417/814/816/817 Include Core Independent Peripherals (CIPs)
Posted on: 25 Dec 2017
Atmel tinyAVR microcontrollers are optimized for applications that require performance, power efficiency and ease of use in a small package. All tinyAVR devices are based on the same architecture with other AVR devices. The integrated ADC, DAC, EEPROM memory and brown-out detector let you build applications without adding external components. The tinyAVR also offers Flash Memory for […]

Capacitor self-diagnostics
Posted on: 23 Dec 2017
The electrolytic capacitor is far from being the most reliable electronic component. One of its failure modes – a gradual loss of capacity – can hardly be noticed until power supply malfunction occurs. Thus, any chance to monitor the condition of the filter capacitors of an electronic device in situ would be a useful thing. […]
Single-chip USB-C buck-boost battery charger
Posted on: 22 Dec 2017
The ISL9238 and ISL9238A USB-C™ buck-boost battery chargers support bidirectional power delivery in ultrabooks, tablets, power banks and other mobile products. The single-chip ISL9238 and ISL9238A battery chargers replace competitive two-chip solutions to reduce customer bill of materials (BOM) costs by up to 40%. Both ICs employ Intersil’s patented R3™ modulation technology to extend battery […]
Temperature Measurement with NTC Thermistors
Posted on: 21 Dec 2017
Thermistors (thermal resistors) are temperature dependent variable resistors. There are two types of thermistors, Positive Temperature Coefficient (PTC) and Negative Temperature Coefficient (NTC). When the temperature increases, PTC thermistor resistance will increase and NTC thermistor resistance will decrease. They exhibit the opposite response when the temperature decreases. Both types of thermistors are used in a […]
Build Your Own I2C Sensor
Posted on: 20 Dec 2017
Since Raspberry Pi doesn’t have a built-in ADC (Analog to Digital converter) to read the voltage off from most of sensors, the best solution is to add I2C ADC chips and modules to your project. Paweł Spychalski faced this problem while building his own weather station that is based on Raspberry Pi. It collects various […]
