Teh Official OMG WTF thread.

He's just procrastinating and rationalizing. You're approaching 30 and you have 0 work experience, you're in a good field but you missed out on a lot of possible experience. This is gonna hurt your chances of landing a decent job for your field of expertise.

None of what you said is false.

But it is overly pessimistic.

Shade, maybe you can help me with something. Do you know electrical circuits? Or anyone else familiar...

Here's my predicament: I need to make an electromagnet STOP working when 3 buttons are simultaneously pressed. Doing the opposite is easy - I just link the 3 normally open buttons and when they are pressed, the magnet works - when they aren't pressed, the magnet stops working.

But I need to do the opposite. Using normally closed buttons isn't a solution because the magnet will stop when a single button is pressed and it's imperative that all 3 buttons are pressed in order to open the circuit. I think I can make it work with a relay?

Lol and I'm going towards 23 and I feel like I'm getting too old and losing my life with this job,maybe I should calm down lol

You're not the only one. Granted, I'm a bit older (27), but I got the same feeling, about life in general, though for different reasons most likely.

Because all the media we consumed when we were under 20 years old installs in us the idea that when we'll be over 25 years old everything magically works out and we'll be rich and successful and have lots of possessions and shit. That won't happen to the vast majority of people. And when we start facing that reality, it's completely normal to feel disappointed with our lives.

 

[Bavanai]

can this work?

 

[HellFire]

As a technician and electrician with qualifications I can tell you that I have no idea what's going on in there <3

 

[Bavanai]

Excuse my no-qualifications electrical drawing, here's a more legible (i hope) one:

Upon pressing all 3 buttons at the same time, the magnet should power OFF. Correct?

Left: power source
Center: relay
Right: electromagnet

 

[madnes]

that should totaly work

 

[Bavanai]

that should totaly work

I am an electrical engineering genius.

Possessions and money are not what get me down Or, to be more precise, the lack thereof. Told you, different reasons but, more or less, the same outcome.

Sorry, I did get some training in EE but it's mostly not my interest nor my domain. You can ask on some EE forums though if the problem isn't urgent.

is that a doomsday device?

 

[Bavanai]

It my "please hire me" device.

So...I'm leaving tonight,4 AM taxi to Bucharest and the flight at 8:55 AM,feels strange man

Ok so I took a harder look at it. It seems to do what you want it to do, with a single exception: no one's gonna hire you if you connect + to +.

Rule of thumb: current needs to flow. Opposites attract.

Hope you didn't submit. Or if you did, hopefully it wasn't that drawing; electromagnets generally don't have polarities since they're usually just coiled wire.

 

[Bavanai]

The schematic isn't for submission, it was for laying out the idea. I know the electromagnet doesn't really have poles, but the one I use has + and - signaling.

I did the prototype yesterday and it seemed to work. Now I have to make the actual device. And one to sell in Greece.

Anyway, can you highlight where the problem is exactly?

You connected the electromagnet's + polarity to the battery's + (through the relay). Any circuit needs to go from + to - for the electrons to start circulating. If there's no other poles, then it's the battery's + and the battery's -.
