you know why I'm "right on the money"?

it's a case of experience........35+ years BTST

almost 20 years in a academic research environment (ME/CE) watching undergrad engineering students fumble along from one mistake to another.......I call it the "arrogance of intelligence" & a major lack of experience

they typically don't even know that they don't anything and spend a lot of time spinning their wheels

a little humility would serve you well in this situation

home repair is probably not the best ng to post for answer your questions.....but honestly if you had clearly defined your problem & all of the requirements of your project you would have gotten a lot of good input from this ng.

There are a lot of people here with a wide variety of skills, education & experience....more than enough to solve just about any problem

as long as its not a moving target

good luck on your project

a bit of advice......the first thing to admit is......

you don't know everything and honestly since you're still in college........you really don't know much

sorry to be so blunt but that's the way things are

a college degree (in engineering?) really just shows me that you can in fact learn that

You're welcome.

Reed switches expensive? You ain't seen nothing.

What other criteria besides small diameter and absolute lowest cost are you not telling us about?

1/2 " metal pipe. 100' or less down to the water. water flucuates by by 5 - 20 feet. needs to run off 2 AA batteries. thats all the details i have.

IN a big way he is to be admired for that. He didn't want to give us enought information that we could "do his homework for him".

Even though in a real design situation, you're allowed to use any help you can get. But in a leading edge design situation, there isn't that much help one can get, so I guess it's good to learn to do a lot of work oneself. ??

I really don't know what is better. Getting a lot of help here isn't the same as your parents making a paper mache erupting volcano while the kid just watches. OTOH, if you give all the facts and the right person is reading, he might answer with such a detailed description of how to do that the student is just assembling it. I don't think anyone wants that, do they?

Yeah....there's a fair amount of truth in what you posted but it is frustrating for guys making the replies to be getting a constant stream of "constraint updates"

that's why the best way these design projects work is a small team of students working together & an experienced older engineer to advise them.....no one does their work for them & with proper guidance they get a better result & a more valuable learning experience

left to their own devices they will typically spin their wheels, waste a lot of time, energy & $'s, get poor outcome & have a poor learning experience.

BTST countless times

design is an iterative process but it cannot iterate correctly without proper specs, knowledge or experience

I have chosen to use a vibrating wire piezometer.
