Anyone know a better way to turn work into energy, or vice versa, other than the steam cycle? That would solve our energy problems.

There are all sorts of ways to turn heat into useful forms of energy. It's just that the steam cycle is still the most efficient for large scale power generation. Cars turn heat into work without steam. They're way more compact, but they're not nearly as efficient.

I've been interested in the subject for some time now and started my first project. Without proper research, just my own vision.
I bought a new bass since the old one was cheap shit. However the old one had more powerful EQ. Both have active pickups. I figured I've got no use for the old bass so I'd take the hardware out, put it in a box and run my new bass signal through it.

At first I got signal go through connecting TRS cable to the OUT wires with tape and the signal IN came from Bare, Yellow or Black inside those grey fat ones (both hold inside yellow, black, white, red and bare (white and red are grounds I guess, since they have been connected together with tape at the end of the fat one, fucking chinese engineers). Hope this made sense.

No matter where I made the signal go (yellow, black, bare or all of them) the knobs didn't alter the sound. Battery connected or not didn't make a difference. So what I'm asking here is, are these knobs controlling the pickups so that the pickup alter the EQ levels, if so, what does the chip do? I think the four knobs are low end, mid/high end eq's, volume and pickup mix.

Now when I try to connect it the same way it just spits out buzzing sound.
<- Messy picture

Feel free to point me in right direction. Where can I study this shit? What am I doing wrong?

When you took the EQ out of the first guitar what did it look like?

>So what I'm asking here is, are these knobs controlling the pickups so that the >pickup alter the EQ levels, if so, what does the chip do?
Since everything is plugged into the board and they're active pickups, it's a safe bet to say that's where everything is being filtered or boosted from, as well as the volume most likely.

It's hard to tell what everything is, but I would assume the signal flow would go something like this:
Pickups -> pickup selector -> tone knobs -> volume knob -> out.

Now since it seems this is an active circuit it's possible those pots are just controlling the chip to do the tone controls, but I just realized, I'm not sure if any of this will matter.

Are you trying to connect the output of your new bass with the input of this and then send THAT to the amp?
That won't work quite as well if at all because the circuit is probably expecting an unamplified signal, and this EQ/preamp amplifies it.
If it does work, like say reducing the level before going back in.I think connecting that many components in line could add some serious noise to your sound, not to mention turning down a signal and then re amplifying it can be really noisy.

Hello /tesla/
I am currently 19 and am thinking about trying to major in engineering. I like seeing how things work, and did fairly well in math and science in high school. But I am extremely uneasy about making such a commitment (6-8 years?) and dropping ~50k for tuition and say... ~70k for living expenses for those total 6-8 years. I also hear engineers have nearly no free time during college.

I don't know what to do. Is this normal to have to drop that much money with loans? Is that what some of you are doing? And how did you figure out if engineering was the right path for you?

>6-8 years?
only if you take 12 hours a semester and have 3+ co-ops, its pretty reasonable to finish in 4-5 years with one co-op. most of my expenses were covered by scholarships and some money from my parents so ill be graduating debt free, ~50k is about right for a state sponsored uni, living expenses depend on where you live. the last 3 semesters have been pretty stressful with work I only go out once a week or so.
I would have been happy with math, physics, comp sci, or any engineering but chemical, I settled on mechanical engineering because my school has a very good engineering program, and it's easy to find jobs in my area, but there's a fairly good demand for them in most parts of the country if I decide to move later.

As stated before, it's a 4 year program. I did a Mechanical/Electrical degree and it took 4.5 years because I was an idiot and got involved with a Sorority girl who turned out to be a whore. If you can, live at home - it costs $8,000 a year in Canada for Engineering tuition, and I paid it all off by working in the Oil Sands.

You only don't have time if you can't manage it. I was able to go drinking once or twice a week with my study habits, just make sure you stay on top of your work.

Also, being able to do math pretty well in High School is a good indication of you being able to learn the more advanced stuff. Just don't go in all hot shit like a lot of people, because in the end, it's not what you learned from high school, it's the process of how you learned it.

So soon I will need to make a choice. I am studying a general engineering course, but soon I will have to decide which course I want to do next year. Right now it's between

"Computer, Communications and Computer Engineering" and "Mechanical Engineering"

I love programming and find computers fascinating but I find the problems in mechanics very intuitive and I like mechanics.

Can anyone help me with some information on these two specialities? Any pros/cons?

Im doing a double degree in both of those! comp sci and mech eng.

The mech has always been easier for me, due to the huge amount of memorization present in comp sci.
However, i am a far superior engineer because of my programming skills. So much of Mechanical engineering has been based off of empirical testing that many engineers can scrape by without programming well. With new technology, many of these fields are evolving to use computational solving. Finite element analysis, fluid dynamics, even stress and strain modeling for beams can be approximated with greater accuracy and without the massive "fudge" factor that used to be necessary.
However, with hindsight i now wish i had simply finished mechanical before doing the programming, as I'm very broke and I'd love to have a ring on my finger and a good job. On the other hand, i can actually make you a robot competently without going DURR DURR gearing? or DURR DURR computers?

TLDR Mech eng, but program in your spare time; its pretty damn useful.

Self study here, reading a book on electricity. I was making good progress on the book, until about the middle when it got into AC and complex-circuit analysis. The book only gives you about 10 questions at the end of a chapter, with no answers to check.

Pic related, the book I'm reading.

depends on what exactly you want to do, if you just want to build speaker boxes for your sounds system then I reccomend you take the right speakers with them. everyone on the internet says it, though I have not ever seen an argument for or against it.
here are some sites for speaker building (the first two are in dutch but I fthink you`ll be smart enough to figure out the designs):

This is a Trompe.
it can make a virtually inexhaustible supply of free compressed air

This system could eliminate the dependancy on oil (that's why it's so unheard of). It is the best form of renewable energy and badly needs development and publicity.
