Every project needs a power supply. As 3.3volt logic replaces 5volt systems, we’re reaching for the LM317 adjustable voltage regulator, rather than the classic 7805. We’ve found four different ...

The car cigarette lighter socket does not only light cigarettes, but can be utilized as an electrical channel for powering tools to work on the car such as laptops and other electronic devices. The ...

There are an awful lot of Li-ion charging chips out there, and you would have thought there was one for every eventuality. But it turns out there isn’t. There is a sort of no-designer’s-land between 6 ...

The resistor and 10 uF capacitor are already forming a low-pass filter, which should prevent any spikes in either current/voltage. I don't know much about laser diodes though, so I am not sure what ...

The circuit intends to produce an adjustable voltage regulator in the range of 0V to 3V with the use of the three-terminal adjustable regulator LM317. Without applying any methodology, the normal ...
