One of the main components in the construction of this circuit is the transformer which is rated with 230V/10V with a given current of 0.5A. It will handle the transfer of electrical energy from one ...

This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...

Often, equipment users wan to replace a defective board without interfering with system operation. They can do this by removing the existing board and inserting a new board without turning off system ...

Researchers at the University of Cambridge have developed a transistor which operates on energy ‘scavenged’ from its environment and say this could enable devices which function for months or years ...
