Sir Adam Beck #1 ten 25 Hz generating units were converted
to 60 Hz or modified as follows:
Units 9 and 10 to 60 Hz in 1956
Unit 3 to 60 Hz in 1970
Unit 4 to 60 Hz in 1984
Unit 5 to 60 Hz in 1985
Unit 8 to 60 Hz in 1990
Unit 6 to 60 Hz in 1996
Unit 7 to 60 Hz in 2009
Yep, the government had to go house-by-house, building-by-building replacing all electrically powered devices that could not be adapted. Thankfully it also happened early in the era of electronic devices.
it's substantially easier to run modern electronics off random frequency power than other stuff like an induction motor. A typical power supply is rated for 47 Hz- 63 Hz. But it'll happily run off almost anything higher than 10 hz and lower than 1000 hz.
universal motors in particular do not care at all about frequency
oh wow, 25 Hz was supplied to homes? I know New Orleans still has some pumps that run on some oddball frequency. It's part of the reason why they never work during the storms (when you need them). The "grid" is just a set of colocated generation sets
On submarines (still flying, just underwater), we don’t throw new underway buddies into the most difficult scenarios right away. We do give them a seemingly overwhelming amount of qualifications to achieve in a very short period of time, but we don’t make them practice the hard stuff until we’re sure that they understand the fundamentals. Because much like ATC, if you make a mistake hundreds of feet underwater (or thousands of feet in the sky), you’re gonna have a bad time.
…kind of. In reality, there is always a qualified individual ready to physically stop you from doing the wrong thing, and there are multiple independent safety systems, interlocks, etc.
While lift ticket prices have maybe doubled in the last 20 years, I am sure costs
For the ski areas have more than doubled, like
You said insurance, but also parts, labour,
It feels strange to write about this, but resolving a health issue, paying off debt, and escaping the nerve-wracking cycle of short-term, low-paying gigs would be life-changing. I am the sole breadwinner, working 50-60 hours a week just to stay afloat, so I don't have the time to prepare for interviews and pursue a stable career.
When you're living paycheck-to-paycheck, even just $10K in credit card debt at 30% is enough to keep you down. ~$250/month merely pays the interest.
Maybe there's medical stuff that needs to get done. Maybe the car needs fixing. Maybe you haven't gone on vacation in YEARS and it's taking a huge toll on mental health. I mean, consider how many people work jobs that don't offer ANY PTO, so even going on a stay-cation costs money due to lost wages.
50k is enough to comfortably live on for a year even in Germany, much more so in other countries. Allows you to completely change perspectives or to pivot your entire career.
I know someone who paid off their credit card debt with an inheritance of roughly that size. It completely changed their outlook on life. Before every month was a struggle to just stay on top of the credit cards. Now they are debt-free and are actually able to save a bit of money every month. And for example able to go eat out without struggle.
Mind you by hn standards this is on a miniscule income. Still, many people are struggling hard and a windfall like this can make a huge difference in quality of life.
Found a place in a rural part of Missouri for $60k at the end of 2019. Everything has more than doubled in value since then. I had no idea what was about to happen when I signed that paper… but I’m sure glad I didn’t wait even a few months. Literally moved in February 2020 just in time to get really familiar with the new surroundings.
Wow it’s a big list. My must have features are left and right y-axis, easy zoom and pan with the mouse, and live updating so I can stream data to plots from industrial processes, updating about every 200ms.
I used kst-plot which was really good. I think airbus uses it too.
These days I am not doing any real time analysis only historical, so I am using Victoria metrics with data fed from a wonderware historian and grafana, since working with the wonderware historian directly is painful, and our samples are one every 15s
I’m curious if anyone has used some of these python plotting libraries that might work for my use cases. Thanks
It is Probably just fine for the next 10 years. Chromecast audio are working great for me with my 70’s receiver and modern mini amp and Bluetooth speakers with line in.
My desk setup is their AD-18 driving L/R bookshelf speakers and a compact subwoofer via its dedicated sub output. I love all the input options including traditional analog, toslink, BT/NFC, USB for high-res: https://www.smsl-audio.com/portal/product/detail/id/566.html
A project that isn't discontinued, among other things.
I don't want to fiddle or think about hw/sw interface or compatibility. Just buy high quality speakers and invest by adding pieces to my system over time.
It only mentions routers and not APs. I am extremely pleased with my tp-link Omada WiFi setup with self hosted controller in a docker image. after over a decade using mikrotik and ubiquiti products I don’t think I would go back for WiFi, and I would certainly be inclined to give a tp link router a look if it’s as polished and capable as their WiFi products.
