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 […]

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.

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

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
