tarp is easy, tin would last forever, or you could rip off the old roof, put on new plywood, cover it with roofing felt and then nail down asphalt shingles like roofers do, or you could just hire a handyman.

Let's talk Sealand and other offshore constructions.

I'm no engineering expert, which is why I'm asking you guys this. If someone were to somehow acquire an offshore structure such as an oil rig, would it be possible to expand off of it? How would this be done? At what point would support struts be needed to hold up any extra land?

Yes, I was thinking about Outer Heaven.

Well, Sealand is a WW2 fort, Frying Pan is a lighthouse designed after oil rigs, and Rose Island was a purpose-built structure, presumably again patterned after oil rigs.

Islands can be built using plastic bottles and foam. Then you can layer dirt and organic compost on top for growing things. if you need to expand, put another layer of bottles on top of the dirt, and start your garden over again. You will need to haul wood and other supplies from mainland for building shacks. freshwater catchment, alternitive energy.

Finishing my certificate in EE. (Pre-Apprentice)

Delmar's Standard Textbook of Electricity is what we use. But basically any textbook involving is going to be the same, since electricity hasn't for hundreds of years.

Also, to solve that superposition circuit: Whoever thought using three power sources to learn superposition is a real asshole to the people who want to learn this type of stuff. You only need two to get the idea.

But in a really crappy way of explaining things because I'm really bad at this:

Basically sort out two of the VT and solve each circuit as its own, you must use Ohm's Law to solve I and VRs. You repeat this process for the other two VTs. Then you must find which way current flows on each separate circuit, it can easily be found with the VTs. After you solve the three circuits, you now put your current directions and VRs on all the resistors. From there, you can solve this problem.

I would solve this but I'm not gonna spend an hour working on three circuit superposition problem.

either the height difference was too great for such a short length so they needed a more gradual angle so they stretched it out with the loop, or its for safety so people dont go rocketing from an expressway onto a slower speed street, so they slow down to execute the loop turn

Learning to recycle old electronics (components) by Fanny Blonnerstere - Tue, 14 Nov 2017 19:16:29 EST ID:zIm1Srig No.7158 Ignore Report Reply Quick Reply

HI guys. This board seemed more suitable than /tech/.

My dear dad just passed away. He was an electronics hoarder (according to my mom at least). He collected a ton of broken, old or discarded but still working electronic equipment in my parent's garage. My dad was more of a collector than electrical engineer. He knew how to solder neatly and could name some components and what their specs meant. But he never really made anything out of his collection. One of the few things I remember was him fixing a radio that needed a component change.

My mom wanted to throw away all the "junk" when dad died, but I ended up taking most of them. I love electronics but I've never been good at them on a technical level. I'm more of a software guy. I know my basic electronics from physics class up until ohm's and kirchoff's laws. I can read a circuit diagram and have some clue about voltage, current and resistance. I'm not a complete noobie, but I'm still really really bad at electronics and have no idea how to approach a project.

I wanna recycle the old stuff my dad left. Salvage individual components, test to see if they work, organize them according to their properties, and make something new from them. My dream for a while has been building a radio transmitter. I've already got a super cool AM/FM receiver that can do all sorts of magic tricks but I lack a transmitter. I've done some googling, but a lot of it flies over my head.

So, I need sources about electronics. I want to learn. My dad left me a soldering iron so I got that covered. I probably should get some tools to remove singular components from circuit boards. The biggest issue is finding out if the components are still functional. Some of the stuff is from the 60s! Any easy way to do so?

Sorry for being all over the place with this post. I only took the mandatory electronics classes so I'm pretty intimidated. No clue where to start building my radio for example. Should I just pick everything apart and then start assembling components that fit together? There are plenty of radio transmitter schematics online.

They are called bread boards.

tldr: All currents through a node sum to zero, all voltages in a loop sum to zero.

Look for an online Circuit analysis class to understand how electricity behaves, then look for an Electronics 1 course and Logic Design course online. That should set you straight.

Fellow electronic recycler & electronics nerd here. What is important? Sadly, Time is also Money.
So, know what to recycle:

dont do:
  • random Resistors, cheap disc type capacitors and random DIP IC
  • random no brand Electrolytic capacitors
  • undocumented IC

do:
  • good branded caps 105°+ Caps (Nichicon ("cooking pot" logo), Panasonic,...)
  • still expensive stuff: like ADC's, DAC's, tantalum caps, precision analog stuff (OPA, precision resistors, voltage references),
    power stuff (High amp / Voltage Triac, BJT, Mosfet; transient protection, power resistors), Inductors, quarz and resonators
  • always usefull stuff: bridge rectifiers, optoisolators, fuses /w holders, small & big transformers
(all above even in DIP)
  • all kind of SMD IC (because storage in ESD safe bags is easy and fun for SMD)

Know them feels, I graduated with mechanical in 2014 right when oil bottomed out. The position I thought I had lined up ceased to exist and I didn't have much luck afterwards due to lack of experience, almost everything in my region is tied to petrochem. I recently started a construction materials technician job for a geotechnical firm just so I can be somewhat in my industry for experience. The pay isn't great but there's so much construction going on I can get plenty of o.t. every week.

That looks like new construction, how the fuck have you shocked yourself 6 times on lines that shouldn't even be hot?

At first, looking in the trash bin, your pigtails looked fine - then I saw that box on the far right side of the OP picture. If you did that, I want to kick you in the balls, how the fuck are you even going to attach an outlet to that?


Also, yes depending on the job (especially remodels), it's common to have multiple crews working at the same time. New construction is a little better on this front.

Honestly, if you can get into only new construction, it's the way to go in my opinion. Remodels can be a pita when you start looking at how previous electricians (or worse the homeowner) have done things.
Like seriously, I've been on jobs where the previous electrician ran 8ga wire from a hottub to the breaker box, ran out of wire inside the breakerbox and crimped a couple 6 inch lengths of 12ga in between the 8ga and the breaker.
I have worse stories if you'd like.

Focusing whole cities worth of electricity to a single block? Electricity isnt like light in that it can be 'focused'. You could make a machine which consumes the same amount of power as what a city would consume, but essentially you're looking at making a huge heater or fan or something which would never recieve full power because the city transmission network is equipped with protective devices to prevent exactly that from happening

It would turn the air into plasma and melt/burn everything.

Probably more fun from up close.

But yeah how would the "power" be transfered to the block? What specifically is it transfered to?

If it is just transfered to everything equally, how high and low would the power be transfered into the atmosphere/earth.
