Cool. Here's one (of 3) in my backyard. About 30 years old and 35' tall.

People on craigslist are always giving away jet ski hulls, but never jet ski engines. what are they doing with the engines? why are hulls so plentiful and engines not?

JohnS_AZ,
@JohnS_AZ@mastodon.social avatar

@MLE_online People stupidly don't maintain their jetski engine, blow it up, then buy a used one for a replacement engine. (and probably ultimately blow that one up ...)

The hams are doing their morning fighting on the radio again.

"Wahhh, how come no one talks to me? ...

You're a piece of shit, Jimmy. When you look up sack of shit in the dictionary, there's a picture of you. You're ugly, worthless, you're just a sack of shit, Jimmy."

"At least he tries to be good though. Pat is a piece of shit, but he's not good at it. Jimmy really tries to be good at being a piece of shit."

Huffing nitrous seems to be of increasing popularity these days, which is of interest to me because people keep leaving heavy duty gas cylinders lying around after they're drained of their intoxicating gas, and I'm wondering what possible use I might find for these cylinders

I discovered quite by accident right now that my bike picks up enough of an electrical charge to shock me (my inner thighs) when I ride it underneath the very high tension power lines that cross over the river bike path.

I want to come back with a multimeter one day and see how much voltage there actually is between me and my bike

JohnS_AZ,
@JohnS_AZ@mastodon.social avatar

@MLE_online It may very well be YOU picking up the charge, not the bike. :-)

Your DMM may not detect the voltage. An electrostatic voltmeter (SUPER-high input impedance) may be required.

I was given one of those 12V, 1.5 watt Harbor Freight solar panels and I think it would be cool to do some kind of solar powered microcontroller project.

The friend who gave it to me said that the panel is not quite powerful enough power and ESP 32 when Wi-Fi is activated. So, that means either using an Arduino or an esp32 without Wi-Fi turned on, which limits my options.

I would like to keep it simple so I don't want to deal with batteries and a charging system. Just solar panel and microcontroller

JohnS_AZ,
@JohnS_AZ@mastodon.social avatar

@MLE_online Maybe hanging some number of 'super caps' on the power rails would give you enough reserve power to turn on Wi-Fi, execute some task, and then turn it back off.

Why are there so many outlet timers for letting you set something like a lamp to come on a 7 pm every night, but there are almost no outlet timers that let you turn something on and have it automatically turn off after, say, an hour, or 25 minutes, or 77 minutes?

JohnS_AZ,
@JohnS_AZ@mastodon.social avatar

@MLE_online And in that vein, a photocell switch that turns things on at dawn and off at dusk does not seem to exist.

JohnS_AZ,
@JohnS_AZ@mastodon.social avatar

@MLE_online Thanks, but that's the opposite. There are tons of 'dusk-to-dawn' switches out there. I was looking for a 'dawn-to-dusk", turn on in the morning, off at night.

@MLE_online The water fountain in the yard for the birds. We'd rather the water sound not be attracting Javalina, Coyotes, and other stuff at night. Have one of those timers you mentioned now, but I like the idea of daylight controlled better.

@lonerfanatic @tootymctootface @jeffowski No you can not borrow money for free. You can deduct the money you paid for mortgage interest from your income which means that your tax is reduced by a fraction of what you paid in interest. And then, you can only do that if you itemize your deductions. Since the standard deduction was raised in 2017, millions of folks (like me) can no longer deduct mortgage interest.

Today's shop work; assembling and painting add-on bee boxes for Lisa's hives and assembling 20 honeycomb frames. (these all come as kits, and have to be glued/nailed together.) Fun hands-on project. :-)

Sayhi to the weird little clamp that I ran over with my bike on my way to work right now. If you ever wondered who would win in a battle between a weird little clamp and a bike tire, so the answer is the weird little clamp

The idea that the sandwich wasn't invented until the 18th century seems completely improbable.

I don't see how no one prior to the 1700s thought to put meat between two slices of bread. I just don't believe it.

JohnS_AZ,
@JohnS_AZ@mastodon.social avatar

@MLE_online Maybe the 18th century was the first time a rich entitled white guy did it.

This has been a warm winter, and it's the first winter in the seven or eight since I've lived in this cottage that I haven't turned the furnace on even once.

JohnS_AZ,

@MLE_online Same here. We haven't run the heat at all this winter. What's more, the past few days I've had all the doors and windows open all day long. :-)
