There’s a joke in the world of radio that all you need for a HF antenna is a piece of wet string, but the truth is that rudimentary antennas rarely perform well. Random pieces of wire may pul… ...

Although it started as a Notion clone, Microsoft Loop received frequent updates to stand out in a crowded space. I took it for a spin and came away impressed. It transformed how I work, and I’m ...

Of course, a “simple” open-loop control system can mean a steeper learning curve. It’s not easy to learn to drive a manual transmission. But if you don’t know how to drive one, ...

This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V to drive 10 LEDs at a regulated current of 0.35A. Often, ...

Open Outlook and go to File > Office Account > Sign out.Then, close Outlook, reopen it, and log in again through that same screen. Expert Tip: Note. This might not be the same email that's having ...

Simple construction allows an open-loop Hall effect sensor to beat its closed-loop counterparts in terms of price, weight, and size; yet it may be susceptible to temperature variation and ...

A signal-injection circuit for control-loop analysis is flat from dc to 200 kHz, isolated from chassis ground and easily constructed with a readily available instrumentation amplifier Brian Keeney ...

Data centers rely heavily on the capability and optimal performance of heat rejection equipment being utilized to function efficiently. When conserving water is a primary goal, careful attention must ...

I have a simple spice netlist for a PLL where it possible to watching lock in on the time domain without too much trouble. This is not a optimize PLL. But it could be a good starting point for the ...

The Loop was ridiculously simple to use. I put the 3.5mm jack in the hole, rolled up the earbud cable, and I was done. The 3.5mm jack sat nicely in the donut ring, ...

Forming the prussik or rescue loop is quite simple, it is just a double fisherman's knot used to tie the rope or cord into a loop. A triple fisherman's knot is also acceptable: Wrap one end of the ...
