It took a days work but I got the wood from the Craigslist seller safely in the dry. I was thoroughly tired after having to load and unload this amount of wood in a day but the realization that I was saving a couple grand helped to lighten my mood quite a bit.

Image

The wood came from a house that measured 28 feet wide by 60 feet long. It's basically the entire roofing system that I bought and if I keep the width and pitch for my future shop than I won't have to cut any rafters or ceiling joists. All of the ridges, birds mouths, and rafter tails are already cut. Also, the rafters were on a 16 inch on center layout, and if I shorten my shop to say 48 or 52 feet and layout on 24 inch centers, then I should be able to frame up the entire shop without having to buy additional wood or close to it.

The backstory is that a neighbor of the seller was going to tear down the house and burn it. Back in the 1970's the house had been hit by a tornado and the roof had been torn off so they rebuilt the roof, which is what I have now. But the original house was really old and fell apart and the owner told the seller he could have anything he wanted, and he spent two weeks dismantling the roof and pulling every nail, even in the 70 plus sheets of plywood! That's a lot of nails and I don't know that I would have messed with the plywood but he did a good job with minimal tear out. The seller asked me to send him a picture of the shop after framing which I will happily do.

My cleanup of the farm continues. I have a constant war with invasive species such as honeysuckle, wild rose, and grape vines. Add to the mix fencing and barbed wire and my days are full.

Image

Image

I have started to make a difference however, and I really enjoy taking an overgrown and nasty area and making it nice. My goal is to create a beautiful and private area in the woods where I can relax and get away. I also will be building a treehouse in the future and have selected a wonderful and healthy oak tree for that endeavor. Unfortunately I can't started on that right away as there are too many necessary measures I have to take first.


And a reminder of why I want to move:

Image

That's the cops at my neighbors house once again, this time searching one of their vehicles. One of these days I will detail some of the more memorable idiocies of the dumbasses next door, but once I move. ;)

Ha! Bad neighbors are everywhere. We are surrounded by them here. There were 5 cops at one of the places down the street about a month ago. It's known as the neighborhood drug house and routinely has a red light on the front of the house...

I'm pretty jealous of your farm adventures. ;)

@monkey

My tolerance is much lower than the average person as I spent an entire career in emergency services dealing with these types of people. After spending a 24 hour shift cleaning up the aftermath of people's horrible life decisions I always wanted to come home to a nice, clean, organized and sane household. When your typical medical run involved grossness on many levels (I could go into very detailed nastiness here), the last thing I wanted to see was the same shit right next to my door.

Next door:

All of them have arrest records, some are in jail right now

All of the women are mentally ill, with drugs playing a large role

Everybody uses drugs

They've burned their house down once already

It's a continually revolving door of people just like them that stay there, I get a new "tenant" every week or so staying there that I have no clue who they are or their background, but I know that if they are staying there, then they have problems.

They once had an alcoholic living in the barn on the property until he got arrested for evading the police after threatening to kill his girlfriend.

Word on the street is that they have used that same barn to make meth. Some of the kids were/are drug dealers.

One kid ( who's in prison now) who burned down the house ( which is one version of how it happened ) also set the neighbors field on fire. I got to put that fire out.

The local and State Police have been there multiple times for various offenses. Everything from arson, drugs obviously, one of them shooting themselves, domestic violence, and a suicide attempt ( not the shooting ).

Over the years they have kept various animals which they don't take care of or contain, which means I get to deal with farm animals getting into my yard and cats and dogs running around my place eating my pets food. Their damn horses got into my yard so often that I had the fix their fence to stop it and I've begun trapping the wild cats coming from his place. I don't blame these animals for their actions but having to listen to cats getting into our food and trash all night plus fighting with my cat is tiresome. Now they have gotten goats which escape all of the time and I'll have people knock on my door asking about 20 goats standing in the middle of the road. Not mine, I tell them.


When they are gone or in jail, it is very peaceful around here. Their place still looks like shit, but at least I don't have to see or hear them.

Anyway, I'm ready to check out. ;)

@Katherine

Fortunately they stay on their side of the fence. And I am actively working towards a solution which makes me feel so much better.

@Jason

I actually like some of their music, haha. I've been binge watching drug addict youtube videos and my favorite one was addicted to meth. He's sober now but when he described in detail how incredible meth makes you feel I almost wonder how many people he convinced to try it rather than dissuade. :?

I felt like a kid today as I made a bridge. My leaping skills, especially with a chainsaw in my hand aren't what they used to be, so I took an old fire ladder ( which is much stronger than a conventional one ), put a board on it and presto, I have a bridge.

Tomorrow is Thanksgiving so no work then, but the woods are looking better everyday.

I like your bridge. I'm going to pass on the meth video though based on your description. Somehow, I don't want to go down that rabbit hole.

Looks like a fun piece of land to manage. I've cleared just small areas of free-growing brush so I have an idea how much work it is (and mine had a special treat - a bunch of poison oak!). It's a good day's work when you can see your progress like that. It'd be fun to help. You know - for a day or two :-P

@SWB

I don't blame you as it's a bit depressing.

@C40

My daughter helped me for a whopping two hours the other day and said she was done, done, done. Ha. It's shit work for sure but the results are impressive.

@Jason

Thanks for the reference. I'm over my binge of this genre for now but I may go back. Been watching Jim Can't Swim videos lately. It's amazing how awful people can become.





I've been clearing land for over two months now almost every day. Last week I decided I would start doing other things before I became insane, haha. Like fixing my damn gate to the property, which would drag on the hump of the driveway making it a pain in the ass to open and close. I had to buy a shelf bracket but everything else I had on hand, including the wheel. Works like a charm now.

Image


If you'll look at this picture, you can see I have a stream running through the property, a stream that has continuously run ever since our mini drought ended.

Image

Indulge me and watch this video:

https://www.youtube.com/watch?v=ZmHY9DkD1Hw

This question is for anybody that has an answer, but it seems tailored to people like Sclass: Is this feasible? and what exactly does one have to do to an old alternator to get it to produce electricity? I think it would be cool to have one of these running at my place but I don't quite understand the alternator component. If anybody has an answer I would love to hear your thoughts.



My daughter recently tried to sell her prom dress on Facebook marketplace and she got the attention of these scam artists. She wasn't quite sure at first so she gave them an address with no ties to our household, but soon after told them to shove off. Even after, we received this letter by UPS:

Image

I guess enough people still fall for this old trick. She was asking $150 for the dress and of course they "overpaid" in hopes of getting her personal information. I'm just curious if a bank would cash this check or would they know it was fake? It might be a fun exercise to take it to a bank and ask them to examine it and explain the telltale signs of a fake. Maybe they would want it for future trainings.



Recently stumbled upon this video:

https://www.youtube.com/watch?v=9Y8LGGf1WJs

Hmmm? Makes one wonder how much he really knows about this whole ERE thing.

I am far from an expert but I don't see why the alternator wouldn't work. As you can see from the video you need a water wheel with a driveshaft.

Then you need a way of transmitting the power from that shaft to the alternator at the right rpm. In the video he is using a belt driving a big pulley on the water wheel and a small one on the alternator. This increases the low rpm of the water wheel to the high rpm the alternator needs.

The alternator creates 12 volt dc which charges one or more batteries. I think you want deep cycle batteries not car batteries but you could test it out with old car batteries. Then you convert the 12 vdc to110 ac with your inverter.

One fun thing about this project is you could probably do it without buying anything.

One thing to consider is whether or not you have to be concerned with overcharging the batteries. It doesn't happen in a car but as a car is charging it is also drawing power. You may need some type of controller if you want to be able to deploy it and not have to watch it. Otherwise you'd bring the batteries up to full charge and then stop turning the alternator.

Side note: you can weld with an alternator. Could be useful in an apocalyptic scenario. :)

I'm still thinking about this. Depending on what you are trying to accomplish, instead of turning an alternator, you could get a broken generator (gas engine part broken) and turn that instead. That would give you 110 ac without needing the inverter but would be less ideal for charging a battery bank (I think).

Another thing to think about is how close you can place your water wheel and alternator to the batteries. Ideally your inverter and battery bank would be stored inside where you need the power. If everything is too spread out, especially if you have a long run of 12v dc, it might not work. Someone better informed can speak to that.

I've read a few electric motor books lately, so presuming that something did stick but with the caveat that I might be talking out of my ass, here goes...

First, a brushed DC motor will work as a generator if you spin the shaft. (This is how an oldschool telephone magneto works ... when you crank it to make a call or torture your victims :lol: ) It will definitely work with a permanent magnet motor (look for PMDC). I don't think it would work with a DC motor that uses field coils instead of magnets to generate the static field without going into some creative rewiring and needing some kind of starting circuit (with a battery) to bootstrap the electricity generation to create the magnetic field. Think about it... if the field coils aren't charged, you'll never get the electricity from rotating the armature coils in the first place. Field coils (there would be two extra wires, like A1 and A2 for the armature + F1 and F2 for the field coils) are typically used for larger motors because they're cheaper than big magnets.

I suspect a brushless motor might have the auto-start problem as well for similar reasons. There's nothing to power the switching circuit that replaced the brushes?!?

The difference between a PMDC and an alternator is that the PMDC will have a static magnetic field with a rotating wired armature on the center axis. The alternator will be the other way around with a rotating permanent magnet in the middle inducing current in a static armature.(*) Theoretically (electromagnetically) they're the same. You could also use an alternator as a motor. In practice, they're optimized for very different things though.

(*) Thus if you see windings in both places, you have something with field coils.

I don't think an alternator will be effective(?!) although that does appear to be what's being used in the video---I didn't watch in detail, just skimmed it. Alternators are made to generate high amp 12V to run headlights, etc. This means thick wires in the armature which means fewer windings which means you need very high rpm (in the thousands). The rpm (rate of field change) times the number of windings is what gives you the voltage. However, the water wheel is providing rather low rpm (in the hundreds?) => low voltage (much lower than 12V). Ideally you'd want thinner wires in the armature which allows room for more windings so you get a higher voltage. You won't be able to drive as much current through thin wires (lest the armature melt) but that's probably fine. If you do need more amps, you need a bigger generator ... and a bigger water wheel.

Also what comes out of the PMDC when used as a generator is more like rectified AC (because of the DC commutator), unless you're powering something "robust" like an incandescent light bulb, you'd want some kind of capacitor in parallel with the output to smooth it out ... and probably also a voltage regulator (ML78xx, where xx is either 05 or 12) after that to keep the voltage constant. (Literally just those two components.)

PS: Also look into Pelton wheels.

@ffj For my bicycle generator on the attic I use this scooter motor with permanent magnets.
Image Image
Jacob is right, alternators are not suited because of the very high rpms required.
This one generates 25 V DC, but a not fully loaded lead accu (standard 12 V) will by itself lower the voltage to a suitable degree. You have only to watch from time to time that you stop loading at 13,5 V (but of course there are gadgets for to control it)

That bike generator is awesome!

You guys are saying the alternator wont work because it is not fast enough but why cant we use gear reduction to go from the slow turning waterwheel to the fast turning alternator? The video shows a belt with differently sized pulleys. If we had an existing waterwheel we could measure it's rpm and do some calculations. For example, if the we is 60rpm and the alternator needs 1200rpm you need one pulley to be 20 times larger than the other (I think).

I read a few posts on other forums and it sounds like charging a deep cycle battery bank from discharged with an alternator will work but isn't really a good way to do things for technical reasons such as the batteries havi g a short lifespan when charged that way. Still a fun idea.

@GdP - Yes, it could be geared up at the cost of friction losses in the gear train + the water wheel working against increased torque by the gear ratio as soon as the generator starts drawing current (+whatever internal mechanical friction it might posses). Make the water wheel wider to compensate.

I have no idea what comes out of an alternator. I'm guessing pure AC(*)(**), so one would need a wheatstone bridge as well (before the battery). I suppose technically one could charge the battery using only that but I can also see why that would be pretty hard on the battery. A capacitor + a voltage regulator or a charge controller should make this as safe for the battery as a set of PV panels.

(*) Because it wouldn't make sense to build in a commutator.
(**) Also guessing single phase on the video on account of it having two terminals.

@Gilberto, J, Jacob

Thanks for the input.

I'm watching lots of videos about the subject at the moment but to tell you the truth a lot of them are just confusing. I may get an old alternator and just mess around with it and see what kind of output is possible. My guess is this guy is treating this contraption as a trickle charger for the battery bank with minimal draws on his system. Like a lot of ideas, the only way to understand it is to actually do it yourself. I just don't want to waste a bunch of time chasing rainbows.

This is interesting. https://www.youtube.com/watch?v=1KyL1-0A0Gw

He says he can pull 500 watts off of this prototype using a hover board motor. I assume that is a DC motor? What about a treadmill motor? Those are DC also.



@Cheepnis

Thanks. The problem was the hump in the middle of the driveway. Unless I wanted to raise the gate another foot, which would have looked odd, I couldn't clear the middle without having to lift up as I swung the gate open or closed. Now the wheel does that for me by following the contour of the ground and maintaining clearance. I wish all of my problems were that easy to fix. haha

I had to look up what a hover board was. It is not what I thought it was. I found this https://www.alibaba.com/product-detail/ ... 4bc6zHm6SR ... which is a PMDC so good for a generator.

Treadmill motors are usually brushed PMDC motors at ~1HP intended to run on 90 or 110V using a speed controller. You can either use a dedicated one (I have a KBIC 125) or reuse the one from the treadmill. The great thing here is that they come with a flywheel. According to the internet, some of the fancier treadmills now come with AC motors. The easiest is to learn to read the label on the motor. It will say what it is. To control the speed on an AC motor you need a variac and comprehensive life insurance :lol:

One thing to avoid are gearmotors ... they will have a gearhead typically to reduce the rpm. I own a 90V PMDC gearmotor with a 1:40 gear ratio. There's no way I can turn the crank on that one. (At least not by hand. I tried.) OTOH as a motor, they have fantastic torque.

Ceiling/box fan motors are IIRC universal motors which can run on both AC and DC. Because of the field coil issue, they're non-trivial to use as generators.

Unless it's a small motor, never plug it into a standard power supply. The starting current is much (up to 4x) higher than the running current which might blow your fuses. A motor controller compensates for all this. Before the invention of electronic control, industrial sites used to have dedicated "motormen" who were responsible for starting the motor. For huge engines, starting is still a "process".
