Hi all, For an applied electronics class I'm currently taking, we have to come up with and build an electronics project of our choosing from scratch. I think it would be cool to build some sort of radar device. I have been looking into phased array radars, radar speed detectors, etc., but a lot...

I've recently started a digital electronics course with a lab component (so far not at all related to the lectures). Unfortunately, there are no prerequisites for the course and I guess they somehow expect us to know a whole lot about circuits, but I'm completely confused. I"ll just ask two...

In an exercise I am doing the term biased is mentioned in the context that the voltage source is biased. Now english is not my mother tongue (and even so I don't know if it's a common word). What does biasing mean in electronics?

Homework Statement I have three problems of the same type that I am wanting to tackle in the next 3 days, so I was hoping that I could get verification here that I am indeed getting the correct answers. I have my final exam coming up, and the section on these questions does not have any...

I'm a first-year electrical engineering student, and I'm really enjoying what I'm doing, but I'd like to find ways to get into electronics in my spare time as sort of a supplementary learning method. I suppose micro controllers would be a good place to start, though I don't know much about...

Homework Statement The bridge circuit below is used to monitor temperature using a thermometer. The thermometer RT has resistance of 100 Ω at 0°C and a linear coefficient with temperature of 0.005 Ω/°C. What is the sensitivity of the bridge (ΔVOUT/ΔT) around 100 °C for ΔT = 1°C? How does it...

Hi all, I am just trying to finish off my HNC in Electronics which I should have done years ago. My idea is to design a conservatory temperature controlled circuit using an oil radiator and a thermistor circuit. I have no idea if this is sufficient enough for project as I am doing it from...

My nephew has a birthday coming up - I want to get him one of those "200 electronics project" kits, but typically they include no real description of why the circuits work (at least the one I had as a kid didn't). So I want to get him a basic book as well. He is 14, is home schooled (by...

In nanoscale electronics, electrons can be treated like billiard balls. The figure shows a simple device currently under study in which an electron elastically collides with a rigid wall (a ballistic electron transistor). The green bars represent electrodes that can apply a vertical force of...

My dream job would be working on things like developing smart phones, tablets, smart windows, and Google Glass. If you have a job like that, what are the everyday tasks? What are the non-conventional tasks? Lifestyle? Work hours? Vacation time? Even if you don't have a job like this, input is...

I am an Electronics Engineer and is heavily troubling my mind for one year already what master degree to pick up,i know i have to make a wise choice.This is how i define wise choice: 1.A master degree should be a respected degree(obviously and the university) to a strict employer's eye.A...

Currently taking an electronics course for physics students and the text we are using is electronics for scientists and engineers by Plonus. Unfortunately, the book seems to have a lot of errors and is just terrible overall. I've heard of the Art of Electronics by H&H, but it seems more of a...

Can you become a mathematician (work in research in think tanks, or teach in the universities) with masters degree in electronics engineering? Or do I need to have a second masters degree in mathematics?

Running a 70mW laser off a 4V 200mA power adapter? Hello All, I have a question regarding what voltage and current I need to supply for a load. I got a laser that's rated at 3-4V and 70mW and I have a power adapter that's providing 4V and 200mA. My question is: How do I make sure I don't...

Hi everyone, I am an italian student (last year of high school) who would like to study engineering at university. I don't know which one to choose between electronics engineering or electrical engineering (I don't know whether there is this difference abroad) I just want to say something...

Well I have no where else to look. I have tried various websites stores etc. I have looked into various sources sites extensively. And so far everything is just a source of aggravation. I can find all of the various parts but its over priced and takes to much searching to find parts. I just...

My major interest is in electronics. I have my college admission counselling in two days, and I'm stuck with this dilemma of which branch to choose. I also have Computer Science engineering as an option. These vacations I took up C++ and it's going well. Question 1 Can I do my masters in...
