USB power testers provide users with the opportunity of examining how much power a device plugged into a USB port is drawing from the port. While this is mostly used by designers who are building USB-powered devices and are trying to evaluate how much power it consumes, it is sometimes...

PowerEver is a tiny electronic board that will keep your commercial power bank running non-stop while minimizing self-drained current. It is user adjustable and is compatible with nearly all power banks in the market. This means that your power bank will never run short of mobile power...

The more the electronic devices to charge, the more the multiple-port USB chargers to have, especially intelligent ones! Yes, charging multiple devices at the same time can be very tiring; from having to deal with the mess of the plenty of cables and adapters needed for the different...

Using the same password on different platforms can be a security risk, but remembering different passwords, used for different accounts, can be quite the task too especially with the need to infuse special characters and numbers, and the fact that you may not use some of the passwords...

The circuit described here is a SPDIF output with a USB interface. It allows connecting Personal Computers, Tablets or Smartphones to Audio equipment including AV receivers, high-end stereo amplifiers or stand-alone audio DACs. It has a infrared remote control receiver that allows...

A USB multitool for monitoring, hacking, and developing USB devices (work in progress) This is an early work-in-progress version of a USB multitool. LUNA isn't yet suited for end-users; but hardware development has reached a point where current-revision boards (r0.2+) make good...

The STUSB4500L from STMicroelectronics is a small-footprint addition to the Company’s USB-C controller IC family designed and certified for pure 5 V sink-only applications. All mandatory features to use the USB-C connector as a 5 V universal power plug are integrated, allowing...

With a code size of 1KB on an ATtiny13A MCU, this tiny module measures voltages up to 22 volts and current up to 5 amps. This project is published by Tirdad Sadri Nejad. He writes: There are a lot of so-called "USB doctor" modules which are used for monitoring currents flowing through...
