Horse is optional - I think the critical item is "A Gabriel"

He is a very interesting part of this whole article along with his son. The amount of physical labor involved is staggering. I've dug some trenches by hand, the longest being two feet deep for conduit, maybe 5 meters at most. Really hard work. Took me half a day. Reading through this article and seeing the amount of physical labor involved actually makes me anxious. But this guy and his son did it all. Most likely wi…

“92 kgs? I can take that by hand” (followed by a photo of the feat) is the money quote.

I've been to this website a number of times over the last decade or so, and I love it. It reminds me of the old internet.

I miss this. I actually miss the joy of the page downloading. I miss the unqiueness of the websites and the content. What we have now for a global internet is great and the tech and the content is beyond amazing but, we have also lost something too.

I remember when this was originally posted, and I am still super impressed with him making his own transformers.

The varnish I used is intended for oven-drying at 140 to 150 degrees Celsius. I don't have an oven large enough to fit this coil, so I heated it by applying roughly 20A of direct current to the high voltage winding. I monitored the temperature by measuring the resistance change of the wire. I can't even...

If you know the temperature coefficient of the wire, this isn't particularly hard to do! You can do it easily by applying a constant voltage roughly of the wanted amperage and then calculating the resistance via voltage and resulting amperage, then feedback to adjust voltage.

It's fairly popular in a wide range of applications, mostly either machines with too much current or too large areas to reasonably measure temperature or parts that are too small (vape coils for example can be used in a temperature coefficient mode).

As you mentioned, this is possible but often followed by lots of regulatory things. I had a look into it for Germany and the easiest way is to buy an old mill and retrofit new technology for power generation. On the other hand, older mills are often covered by the protection of historical monuments and can therefore not be altered as you like. This should really be looked into before buying anything as it will be an…

On a stream this size, even if it is technically illegal, there is no way the government is going to find out about it

You'd be surprised how much work goes to protecting the environment in germany. Or protecting environment regulations.

And the communes take the state of their waters very seriously as well.

You'd likely also upset various environmental groups due to a lot of protected species living around.

I don't get it, what have we lost? Having to wait for pictures to load? Surely this is just nostalgia?

We've (mostly) lost the idea of a content creator just creating content for the joy of sharing it, and transmitting it on their own through their own website using their own rules. So much content is now mediated through "platforms" that are beholden to a complex network of surveillance capitalism and its economic pressures.

It's actually refreshing to see someone doing their own thing, like, truly their own thing.

That said, the dude could use some CSS-skills.

Although I can totally imagine the reaction of someone like that to modern web frameworks. He might be inspired to roll-his-own... he did with EDA CAD as the creator of KISSCAD.

There’s a very cool hydro system built over a few years by a YouTuber called ‘Mr HydroHead’ over a bunch of videos spanning several years - the first here: https://m.youtube.com/watch?v=edEhvmNlYqk Pretty impressive how much power these things can produce!

I've watched this series before too, and I can attest to the fact that it re-ignited my childhood dream of building by own hydroelectric power system.

You are misunderstanding. He runs each wire in a separate, sealed insulating cable pipe. These would most likely be 1-1.5 mm wall thickness PVC.

Am I right then in assuming each wire's insulator provides 600V isolation so two side-by-side would provide 1200V isolation, and the PVC is additional on top of that?

No, the wire voltage rating is the maximum between any two conductors known as the line to line voltage.
