Definitely. I think we'll see the decline of traditional automotive and small engine mechanics over the next decade, but I don't think heavy diesel mechanics will be going anywhere any time soon...
This is great. I want to get into homebrewing in an attempt to save money in the long term... I know not many hobbies work out that way, but good beer is so damn expensive. When I did back of the envelope math, it seemed like it'd be easy to save money doing homebrewing.

Hell, even cheap beer is expensive. I make 10gallons of a Miller Lite clone at a time, which is about 4.5 cases for about $9. The savings is real. ROI all depends on how fancy your equipment is and how much you drink. It's also not difficult to make any beer you can buy or imagine.
My next attempt will be to grow and malt the barley myself. I'm already growing hops and attempting to catch my own wild yeast. If I can manage all that, the cost will be close to zero.

Whatever you did, that's what you planned.
We got several of the early (1st?) gen Kobalt 80v tools and couldn't be more pleased.
Picked up the push mower with 2 batteries on a close out when the next gen was rolling out, 4 batteries total now.
My standard answer when anyone tries to talk bad any sort of battery powered tools and battery life is that "they last as long as I care to weed eat or mow without taking a break". People who don't like them most likely have never used them.
That's basically my path as well. Mower, string trimmer, chainsaw, blower. Four batteries, three chargers, can easily run as long as I want, even mowing grass taller than the mower. The string trimmer takes all the usual attachments, I run a cultivator and hedge trimmer with it. No issues, no lack of power.
Battery electric isn't for everyone, and it's not for all uses, but it's phenomenal for a lot of people, and for a lot of uses.

Pulled out my Canon 1Ds camera to take pics of my current art work and found the battery and backup battery dead dead dead... thought maybe I could repair it so opened on up and found a bad cell 18650 and tried to replace it unsuccessfully with a flashlight battery but the top nub was too long so didn't work... three cells cost about $25 but Ordered a third party replacement battery for $21 and it works. but still the challenge... took the backup battery apart (more carefully 
) and was able to replace a defective cell with one form the original bad battery pack so ... and it works! Woo-Hoo. All this to take pics of my Graphite Artwork in Progress:

Not too long ago I experimented with radiative cooling.
The temperature of space is somewhere around -450 degrees F.
The amount of heat radiated from the earth has to equal the amount of solar heating for the average temperature on the planet to remain reasonably constant. Most of the radiative loss occurs at night.
We can heat our house with the sun. Why can't we cool it with radiative cooling?
I managed to keep a small shed under 75 degrees all summer using an old solar hot water panel as a radiator. A fin coil unit inside the shed coupled to the panel with copper pipe. The system was evacuated and charged with refrigerant.
IR radiation would cool the panel. Heat from the shed would move refrigerant vapor up to the panel and the cooler panel would condense the refrigerant which would flow down back to the fin coil.
The shed was very well insulated so it never warmed significantly during the daylight hours.

Ahhh, now THAT is a good point! I have made it my passion to NEVER use ANY ethenol gas in ANY small engine devices. ETHENOL FREE ONLY! Run the carb dry before storing. Ever since I started doing that, all my tools start on first or second pull every time.
I do love my battery operated DeWalt screw gun though.

I bet SWMBO hates it when you stop and say "we've got a puncture... pass me down the spare, please"
The tire and rim are 650lbs. I have a chain hoist to raise and lower the spare along with a 25 ton jack and cribbing to lift the axle.
In case anyone is interested, I tore into ithe leaky wall/window again with the rage of a frustrated homeowner ticked off at both his own folly and the builder's incompetence that contributed to the leak (would not have needed to tear into it the first time around had it been done right the first time!). I do believe I found the issue and know the fix. Hardware store run is imminent.

Best of luck I can see how frustrating that would be
That doesn't work. Years ago my OH made his own beer. IIRC it cost about 1/6th of the price... but, being on tap at home, he drank at least 6 times more than beer he bought

They build there without house wrap? I see they used fan fold but it doesn't cover the whole wall? The fan fold at a minimum should have been run on the outside of the top window flange, not behind it. A friend of mine had someone side his house and he installed fan fold instead of house wrap. The fella siding it ran the fan fold just like yours and water ran in every time it rained. He borrowed my off road forklift and scaffolding to pull the siding off and properly flash it. He said he should have sided it himself as he ended up having to do twice the work fixing the mistakes. This is how I do mine: House wrap on wall, on windows the wrap is cut and ran into the opening except for the top. Starting at the bottom, the flashing tape is ran across the bottom with overlap inside the opening and inside corners covered. Flashing tape up each side extending past the bottom and top. Flashing tape on top is under the house wrap which is slit slightly on each side. After installing the window, the house wrap goes over the top window flange and I run flashing tape again all around.
When installing siding, there is a metal drip flashing at the bottom corners to force any water to the backside of the siding so it runs out the weep holes in the siding. If I were you, I'd pull the siding off all around the window and see if there is any drip flashing in place. Most don't install it and years later when the window needs replacement they find under a window the sheeting and even studs or sill is rotted.
I won't install a round window like that if given a choice, very hard to flash out. Where the half round meets the 2 single hung windows is going to be a problem. I see caulk there which will not work, it needs proper flashing. To install flashing, it really should have at least 6 inches minimum in between to even have half a chance to flash it properly.
Yeah I was shocked to find no house wrap. Not sure if it is because they didn't do it as much back in 1999 when it was built, or because the builder cheaped out. Probably the latter. There was NO flashing around the windows at all. Just stuck in a hole in the side of the house with some caulking. What prompted me working on it the first time was rotted sheeting, studs, etc. I had to rebuild all that. My mistake was leaving that half circle window in place and just redoing the other two below. So now I get to yank the top half circle window and redo it with flashing and all that.
.If I had my druthers I'd take everything off, replace the random bits of foam board with actual sheeting, wrap the whole house, reinstall all the windows.... Not likely to do that though.
I suspect I'm going to have to do some repairs to another window install on the south wall. Not cool...

My place that my grandfather finished building in 1993 also had no wrap (he was cheap, and it wasn't as common back then). All the windows need to be replaced; I'm removing the siding, adding a wrap and/or possibly a foam layer for extra insulation, and going back with colored metal roofing vertically. That way I can use new-construction windows have a more durable exterior and increase my insulation value.

Try having an 80+ year old house that also was cheaped out on in recent years. My roof, which was replaced a couple years ago before moved in, has leaks from tons of popped nails. They also re-used the flashing, so there's just a bunch of silicone holding water back. As you'd expect, it's also bottom-of-the-barrel 15-year shingles.
Basically, gonna have to get the whole thing replaced a lot sooner than expected.
The house, being as old as it is, also seems to have zero insulation in the exterior walls. Anyone ever had spray-in foam insulation done to a property? Seriously considering that, as we really, really don't want to rip out all of the drywall.
I could go on, and on, and on about the various issues between just being an old house, and the extremely questionable "upkeep" that had been done.

You can always do one side at a time. It took 3 years to side my whole 1905 house. It had aluminum from the late 70's on it plus the original cedar.
Today if I was to do it again, I'd put at least 1" ZIP panels on the outside and tape all the seams. No housewrap needed and I gain the R value with a full thermal break.
I'm planning on building a detached heated garage and I am considering the ZIP panels for sheathing. Not cheap but neither is plywood or OSB. Then dense pack in the walls for insulation.

Back in the day, they used what's called Balloon construction, which means there may not be firestops in your walls. That makes it much easier to go the cheaper "blow-in" insulation route. For open cell or closed cell foam, you will need to rip out all the sheetrock first.
Most of my houses have all been over 100 years old. They don't build them like the used to, and once you go 10 foot ceilings, you wont want to go back to 8 foot. That said, your energy bill will be higher due to the lack of insulation, but thats why we do solar, right?

I blew cellulose in my old house and a rental that I still own. Both had plaster walls with backplaster that was in good shape. My old house just had cedar siding so I pulled the nails out of the siding every 5 feet and blew in from the outside. The rental was done on the inside, simply used a diamond tile bit to drill a hole then use a hole saw on the lath. Easy to patch later.
I always just used full square footage, didn't subtract anything for doors or windows and used thickness that was higher with the back plaster. I would end up with 1 to 2 bags left over so it definitely was in tight. Cellulose was fed slow with air fully turned up. You can't do that with drywall, it will blow it right off the wall. I made a nozzle where it was necked down from 2 inch hose to 3/4 inch. Worked very well, nice tight pack.
Many builders are moving away from spray foam and using dense pack cellulose with netting before installing drywall. Works well with double studded thermal break walls.
