I'm using an ATmega8515 microcontroller for a one-off hobby project. This chip has an external memory interface which can directly address 64 kilobytes of external SRAM.
ATmega8515 datasheet.
For my ...

The typical approach to interrupt the flow through a circuit is interrupt it at a single location as in the left image.
Do any power loads require both power lines disconnected by the switch as in the ...
|
I frequently utilize DC/DC step-down converters in many of my projects. Mostly these converters have a low voltage input (Vin_max = 30Vdc) and low output current (Iout_max = 1-2A).
There's a plethora ...

I was exploring a lumped approximation of a distributed RC network (sort of a lossy RC transmission line/ladder network).
Everything made complete sense until I observed the voltage "gain", ...
|
For the last few years, I have been searching for an adjective that describes all connectors that fit inside a shrouded connector. I have not found a satisfactory one. I am about to go to press with a ...
|
Ok, I promise I have checked and rechecked values here.
I needed to make an LED circuit for a Christmas display using one white LED inside a Santa Claus figure to replace the incandescent light bulb ...

What are these shiny metal-like components in the images below?
Is that kapton tape covering for ESD protection?

Why do you need to store the voltage for some time in a capacitor? I've always assumed circuits to work when you power it on and stop when you power it off.
Why can't the whole circuit be drawn ...

In my home, I have some halogen spot lights, which have an energy efficiency rating of 'C':
I would like to replace them with more efficient LED bulbs, but looking on the Philips website, they claim ...

I have never understood input and output impedances of an op-amp. If anyone can explain what these two terms mean in an op-amp I'd highly appreciate it. Thank you!

I know mAh tells how much milliamperes a battery can deliver in an hour. But does that also tell how many hours the battery would last? Sorry but I don't really get it. If we're talking about a water ...

How do I know when to use lead, flux-core, lead-free, or any other kind of solder out there? Do you have any tips on solder gauge for specific applications?
|
I would like to know how the mechanical rotor frequency [Hz] can be obtained from the electrical stator frequency [Hz]? This is no homework! I have consulted several books as well as the web but could ...
|
I was taught that if you want to change the direction of a three phase rotating machine that is rotating in forward direction, you interchange the phases. Since the phases has the same features (...

Can you answer these questions?

I have an RC circuit connected to a switch node as a snubber. I am facing difficulties determining the required power rating for the resistor. I have looked at this and this, however, it remains ...
|
I looked up this article https://www.electricalpereview.com/base-impedance-single-three-phase-values-equal/ and I am really confused about the final equation.
The author says that this applies for ...

I have been having problems driving WS2812 LEDs; the radiated emissions were too high to pass UK tests. See Radiated emissions from WS2812 LEDs
I finally bit the bullet and went for LEDs on a printed ...
