The fact of having a CNC available at home gave me the freedom to build stuff more easily and quickly than before. Without this machine parts would take some time to manufacture and most likely would not end so perfect. This caused new ideas to be easily implemented. This was one of those ideas that

Northwestern University researchers are the first to develop a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. The low-cost, environmentally friendly solar cell can be made easily using “bench” chemistry—no fancy equipment or hazardous materials. “This is a breakthrough in taking the lead out of

The traditional three op-amp differential amplifier’s signal to noise ratio can be improved by 6dB by adding a resistor and slightly changing the connections. There is a trade-off though: The traditional topology has a high input impedance, whereas the low-noise version has a lower input impedance. Figure 1 depicts a traditional three op-amp differential amplifier.
Differential amp has 6dB lower noise, twice the bandwidth Read More »
Company Quectel brings to a market its first high-speed module EC20 which you can try yourself. More than fifty developers worked for over ten months on this module. We´d like to share with you its parameters, as well as hints, which can make your work with this module easier – this is our biggest bonus
The smartphones carried by passengers on board a Malaysia Airlines flight could yield vital information about what happened to the missing plane. Almost nine weeks on, the search for flight MH370 has come up with nothing. A robotic sonar-carrying submarine is now searching the seabed 2000 kilometres off Perth, Australia, but after scanning 314 square

Description The MAX98355A/MAX98355B are digital pulse-code modulation (PCM) input Class D power amplifiers that provide Class AB audio performance with Class D efficiency. These ICs offer five selectable gain settings (3dB, 6dB, 9dB, 12dB, and 15dB) set by a single gain-select input (GAIN). The digital audio interface is highly flexible with the MAX98355A supporting I²S

Consumer’s voracious appetite for quick access mobile content is obligating the need for high-resolution, high-speed data converters in their mobile internet devices. Whether the transmission pipe is via cellular networks such as LTE or via local networks such as WiFi, the end requirement for the data converter remains largely the same, those being higher bandwidth,
