Woman and Electric Eng?

Where have you been al this time?!

General consensus of women here study either Industrial or Chemical Engineering.

O rly? Haven't noticed yet since I haven't stated my chemE courses yet. Tons of women in organic chemistry though. Kind of surprised me.

Hello fellow Engineers.

3rd Year BEng Electronic and Communications Engineer here

I know **** all, so don't ask me questions

Not at all. There are generally periodic exams on several chapters of material, which count for maybe 20-30% of the grade combined, and then at the end of the course there's a final exam which covers all the material in the course, and that counts for 20-30% alone. The amount of periodic exams varies from course to course; my chemistry class has five exams and then a final, whereas my ECE class only has two, and then the final.

Yup, putting it simply the rotating section is made of mild steel, which obviously has a different reluctance (permeability) of the air. It has "teeth" along it's edge, ie it's not smooth. Call this the trigger wheel.

The cylinder pointing at it is also mildsteel, but on it's end is a neodymium permanent magnet (approx 1200 gauss, or 0.12 Tesla) and along it is an 175 turn coil of wire. Call this the VRS (variable reluctance sensor).

As the magnet is only 2mm from the trigger wheel the magnetic field passes through the trigger wheel, but as the trigger wheel rotates so the teeth mean that it "moves" further from the magnetic field and it's reluctance affects the magnetic field less.

This means that as the wheel rotates the magnetic field changes.

Now as faradays law of induction (I think it's this one) tells us an electro-motive force is induced in a charge carrier perpendicular to a changing magnetic field. Ie because the magnetic field perpendicular to the coil is changing a voltage is induced.

This is the voltage you see on the oscilloscope (the sine wave)

edit - The reason there's a PCB on there is the other part of that device, it's also a rotary encoder. The pcb has copper tracks that carbon brushes were meant to run along, and the tracks alternate between copper and plastic, so conductive and non-conductive. This would produce binary words representing angles of rotation. However I never managed to get the brushes, so that part is untested.

I don't want to sound like a suck-up, but I wanted to say that I've always admired your amp building work in the GB&C forum, and I aspire to have a similar level of knowledge and experience some day.

Just thought I'd say it while I had the opportunity.

Was a Chemical engineer, but switched two years ago to Biomedical engineering. its much better. has elements of medicine, mech e, EE, mechanics, chemical engineering and programming

I'm in year 11 right now, and I want to do engineering in university (thats 2.5 years from now).

You guys are my inspiration...

Going into Final Year of EE. I just got the okay for my senior project which has a lot to do with trying to design a transistor based amplifier to mimic tube sound. Its not digitizing the sound in anyway, but rather biasing the transistors in such a way, and controlling the input, so that they clip the waveforms similar to the way that a triode does.

Glad to have graduated with my ME degree a year ago. You'll be happy when it's over.

sashki

I heard that the reason tube amps sound the way they do is because they amplify both odd and even harmonics (or create odd and even harmonics due to clipping, I don't remember exactly) whereas solid state amps produce mostly just odd harmonics.

Is any of this true?
