Here’s a great little shortcut that uses the new Set Reminder action in the newest v2.1 of Apple’s Shortcuts app. Tell Siri that you want to take a nap, and it will ask you for how long. It’ll then ...

A family of ultra-low-power system timers is intended specifically for reducing power during system sleep time. These ICs, called nanotimers, provide various methods for a system to enter a no-power ...

Over the years, various power-off circuits have been published. However, the circuit proposed here is very simple and has excellent characteristics. It features a fast power-off transition, with only ...

Most switch-mode power supplies rely on a PWM (pulse-width-modulated) output that is controlled via voltage feedback. A 555-timer IC can inexpensively perform PWM. The circuit in Figure 1 shows how to ...

The venerable 555-type timer makes an effective driver for power MOSFETs, but you have to understand the drive situation when selecting the correct variation of the basic timer. This idea shows how ...

Alex Ovechkin has done it so many times that it’s tattooed in our brains. You can see it now: the Washington Capitals’ generational scorer, standing motionless at the top of the left circle in one ...

WASHINGTON --The final seconds of the Washington Capitals power play are winding down and their second unit is on the ice, but Alex Ovechkin remains in his usual spot in the left circle. The Capitals ...
