The USBKill is a device that stress tests hardware. When plugged in power is taken from a USB-Port, multiplied, and discharged into the data-lines, typically disabling an unprotected device. Why would anyone use a USB killer? A USB Killer is … Continue reading →

A USB drive can get corrupted due to varied reasons, from sudden power failure, improper operation, unplugged directly without ejecting to USB failures like file catalog corruption, etc. Usually, you will be told to re-format that USB drive in order … Continue reading →

You will be fine with a 650w provided your cpu isn’t anything crazy like a 18 core intel 2066 with a heavy overclock. The problem you may run into is not enough connectors. One 8 pin for the 1660 and … Continue reading →

The colour of the LED is determined by the composition of the materials used to create the LED. These materials determine the voltage drop across the LED. so a particular voltage drop corresponds to a particular colour. Different colours have … Continue reading →

For example, here is a profile of the voltage for a ‘classic’ 3.7V/4.2V battery. The voltage starts at 4.2 maximum and quickly drops down to about 3.7V for the majority of the battery life. Once you hit 3.4V the battery … Continue reading →

Hot is the center pin. If the jacket sleeve is hot, the wires are reversed. With a plastic fairing, the lighter will work either way. Which wire is positive on a cigarette lighter plug? The positive pole is deep inside … Continue reading →

Any 12 volt source will power your router and it will only use as much current as it requires. The current rating on power supplies refers to the maximum they will deliver if the device requires it. What voltage does … Continue reading →

The positive pole is deep inside the bottom or back of the outlet, while the negative pole is the metal clips on the side of the outlet. What wire is hot on a cigarette lighter? Hot is the center pin. … Continue reading →

Most pedals require 9v DC power and have a very low current requirement but pedals to watch out for include powerful digital pedals like the Strymon or Eventide pedals. What kind of power supply do guitar pedals use? 9V powerVoltage … Continue reading →

Keeping your battery plugged in for extended periods of time will not cause it to be over-charged. If your battery remains at or near 100% most of the time, Lenovo recommends setting the Battery Charge Threshold to limit the battery … Continue reading →

As opposed to how often you need to shut down your computer, your smartphone has a more hard and fast rule you should live by: once a week, shut it off, let it rest at least one minute, and then … Continue reading →

Any switched-mode power supply that gets its power from an AC power line (called an “off-line” converter) requires a transformer for galvanic isolation. Some DC-to-DC converters may also include a transformer, although isolation may not be critical in these cases. … Continue reading →

Voltage levels UARTs use two voltages: one voltage indicates a 0 bit and another voltage indicates a 1 bit. What voltage exactly is used depends on the device: RS232 serial ports use negative and positive voltages, up to -15V and … Continue reading →

1 Answer. Show activity on this post. The problem with using a resistor is that its voltage drop varies depending on how much current the motor draws. At 60mA you would need (18V-12V)/0.06A = 100Ω, but at 300mA you would … Continue reading →
