My attempt at solution says it all.

how can i do that if my PC is using the latest Ubuntu release compatible with a 4 MB RAM PC?

The standalone Seagate SSD that I got for backup failed completely toward the end of a massive transfer. Fortunately almost everything I valued was still available elsewhere. I bought a Seagate hard drive to replace it.

I am working on an electrical engineering project. However, I have come across a specific mechanical engineering problem. I have attached an image to describe what I want to do. I have primarily a stator core (made out of electrical steel laminated sheets) named part number "1". I have a...

My Google-fu has been failing me on this. I'm looking for a good variety of online resources and textbooks on the design of audio equipment. The level I'm looking for would be for upper-level undergraduate or intro graduate level electrical engineering. Topics must include how to best isolate...

In interpretations of quantum mechanics there are two types of physicists: those who care about ontology and those who don't. The ontologists, or realists, want to know what is the world made of. The non-realists, on the other hand, think that this question is not relevant to physics. Usually...

I need to understand the below hardware circuit I am not sure about the type of the signals at signal1 and signal2, i have assumed DC signals initially. Then when i simulated in LT spice, the signal at Output is +5V. But if i assume the signals at signal1 and signal2 as Sine wave, then C1 and...

Hi guys, 1. Most of the design textbooks which I have seen on computer architecture put stress ONLY till the RTL design of computer architecture. But the story of computer system design goes much beyond the RTL description(i.e how RTL design is converted into actual hardware) 2. We begin from...

Hey all, I want to buy Ipad Air 5th Gen Tablet. Currently My computer has this specs: CPU(s): 4 On-line CPU(s) list: 0-3 Vendor ID: GenuineIntel Model name: Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz CPU family: 6 Model...

Suppose one knows well the laws of physics but knows nothing about computers and IT. Would one be able to deduce how a computer works only by studying its hardware? Could one rebuild the software code and understand its meaning only by looking at the internal flow of bits in its CPU?

let's say I do file an object under an open hardware license then either I or someone else wants to patent it or something really similar to it, would it be possible? also for how much time does the open hardware license last? probably not the right forum where to ask this, probably I should...

We have a system that requires software to program a fairly complex frequency synthesizer IC. Given the desired frequency, software executes an algorithm to calculate the values needed to be programmed into the physical device. We would like to have this algorithm contained in an independent...

Hi. I have to drive a motor using TI's CC2540 blue tooth IC. The order is already placed for IC and CC debugger. I have very limited time to design it's hardware as well as software. I think hardware part is easy for me. However in case of software I need verbal suggestions as soon possible like...

pls post your thought here I need this for my homework :)

Hi folks, This time is not a book, I would like to know if exists a journal explaining how a qubit is actually built, I mean the hardware not the theory. Indeed I am interested in any hardware related with these technologies. I know this field is still in an early stage and they are still...

Recently i am trying to put in use a stock of old 74x series microchips manufactured around ~2000 AD. Unfortunately, one of microchips 74HC14 (hex schmitt trigger inverter) in SOIC-14 package have exploded in test setup in the moment the power was applied. Loud "popping" sound, flash of blue...

Is this thread appropriate for some basic computer science hardware and architecture questions or are the posts in here to be strictly related to specific Programming Languages?

My two years old son loves lights and computers. I was thinking to buy an Arduino or a Raspberry pi like single board to control a LED matrix panel. What I want is to be able to control individual LEDs by pressing on keys on a keyboard. Example: by pressing "a", a LED lights up, "b" another LED...
