The scientists came up with a synthetic metal-organic framework (MOF) membrane capable of filtering lithium ions very fast and in a highly selective manner, the team said in their paper published in the journal Nature Materials. Can lithium be made … Continue reading →

Although foreigners may use middle names in Japan, middle names for the Japanese themselves are completely unheard of in Japan, and documentation such as forms, passports, and family registries (equivalent to marriage and birth certificates) have no place to write … Continue reading →

Your phone is charging and your LED light is flashing red. Can you power on the device? I would recommend that you try to force reset your device then try charging it for 30 minutes or until you see a … Continue reading →

AC adapters are used with electrical devices that require power but do not contain internal components to derive the required voltage and power from mains power. The internal circuitry of an external power supply is very similar to the design … Continue reading →

Wi-Fi Power Saving Mode This Wi-Fi power-saving mode is a built-in mode that allows devices to save power by analyzing the data usage pattern with time and then making sure that the Wi-Fi doesn’t drain too much battery of the … Continue reading →

Wifi in fact consumes a lot of power, specially if encryption is involved. The primary issues are the DSP and radio transmit power. In power saving mode, the DSP (like other CPUs) may run slower. The power radiated determines the … Continue reading →

Voltage comes in two flavors (yum): Alternating Current (AC) and Direct Current (DC). Here is a quick tour of the differences. Direct current voltage is what comes out of batteries. The battery is at 9V, and it pretty much keeps … Continue reading →

A power supply takes the AC from the wall outlet, converts it to unregulated DC, and reduces the voltage using an input power transformer, typically stepping it down to the voltage required by the load. For safety reasons, the transformer … Continue reading →

A USB port that consistently overheats can point to all sorts of serious problems, including motherboard or power supply issues. How do you fix a overheated USB? Unplug the USB stick from the current port and computer, and try plugging … Continue reading →

No, you can’t do that. If the batteries are at 10V (under no load) they are almost fully discharged and if you try to draw significant current from them, their voltage will probably drop to near 0 volts. Can we … Continue reading →

With a 9V block battery, you can use the VIN pin of the ESP8266 NodeMCU, that is internal connected with the 3.3V AMS1117 voltage regulator and therefore you need no external components. Can I power NodeMCU with 9V battery? The … Continue reading →

All USB ports are 5 volts DC. The transformer (or computer) will take care of converting the 120/220 AC current to the necessary 5 volts DC. Is USB A 12v or 5V? Since USB connections put out 5v DC power, … Continue reading →
