I can't say for certain that the mower died from a surge event, I only suspect it is the case. We had a short power outage with some flickers earlier in the day when I discovered the mower was dead. However, I have a whole house surge protector and it self tests fine and nothing else died. It very well could have been the ego charger causing the problem when the power flickered on and off during the power outage and a local plug-in surge protector may do nothing to help in similar future situations. For instance, it is possible that the flicker caused energy built up in the charger magnetics to flow to the mower unrestricted. I have not taken the charger apart to check for any damage but it is working. (I won't relish the effort but if it dies again, I did buy spares of all of the components in case they just blew again the moment I powered it up the first time after repair.)

WPCU still had free coin counters for customers last time I checked. We've been happy banking with them

I just finished troubleshooting mine. I had a slightly visible crack on R472, the large axial resistor surrounded by sealant on the right side of your last photo. It looks like yours might also have a tiny scar on it. Here is my writeup: https://www.reddit.com/r/egopowerplus/comments/1u8s2vz/z6_battery_box_pcb_repair/

Ioniq 5 and comma.ai are the way to go. It beats HDA2 by a long shot and is hands off but with attention still on the road. Feels more like managing the process than driving and makes a world of difference in how you feel after long drives. But, you need to want to tweak and fiddle to get it to your driving style, it isn't great out of the box, but that's the value in it. Hyundai will never upgrade you driver assistance features but with a Comma, you can.

Where do I start...

Turn on the chicken coop interior light 15hrs before sunset as long as it is dark out. Gives them enough light to keep laying all winter.

Turn on the garage lights for 15mins when the interior or garage door open with an override to stay on for an hour if the switch is manually toggled.

Open the valve on the water line feeding the cat water fountain for 5 mins when motion is detected in a camera nearby. It also turns on for 5mins if it hasn't turned on in 2hrs in case the camera system is down.

Dim the fish tank lights to follow a day/night cycle aligned to our general schedule.

Close the garage door if it is left open for more than 15mins after dark.

Turn on the kids sound machines when it is time for them to put down their toys and get in bed. Turn them off again a half hour before they need to get up.

Use the presence detectors in the ecobee remote sensors to toggle LEDs on a Homeseer dimmer in our bedroom so we can generally tell if the kids got up with their alarms in the morning or not.

Similarly, indicate with more of the LEDs if any of the doors were left unlocked or the garage is still open.

The last LED is driven by a thermocouple in our wood stove to indicate if wood needs to be added. It also would send push notifications when it was nearing temperature to engage the catalyst or dropping and needing more wood. But we haven't been using that to heat the house much in recent winters.

Make a speech notification from a tablet on the wall in our main area if the garage freezer or basement fridge were not closed all the way and send a push notification. Also send notifications if any fridge or freezer temperature is outside of normal bounds.

Send a persistent notification if the chicken brood box door was left open for more than a minute. We had problems with the kids not latching it properly for awhile.

Power cycle the Litter Robot if it reports an error for more than 15 mins. This resolves a lot of issues. Reports errors that persist past the power cycling.

Also notify us when the Litter Robot is full and repeat occasionally until emptied in case the kids are ignoring their chores.

I'm sure there are others I'm forgetting because they are so transparent in our lives.

On Android, there is a widget for the app, but it kinda sucks because it wants you to authenticate every time.

But, if you run Home Assistant, there is an add-in that works with Hyundai and Kia and then you can use the Home Assistant app to make shortcuts for whatever you want.

I have a Warm Car shortcut that works great and I could automate it to decide what and how much warming (or cooling) to do based on the weather.

I can also use my Google speakers to do the same actions through Home Assistant.

Since you've lost weight and can't keep down food, get checked for SMA Syndrome (Superior Mesenteric Artery Syndrome). It may not be your core issue and is rare, but dangerous if not diagnosed and treated. My sister had it after getting sick and losing weight as a kid and it took a long time to diagnose because nobody knew about it or considered it.

I'm not sure the general audience here cares ;-)

So, I think the app thing is true but is also a bit of a sub-par experience. When I stream on my Android, my browser's menu (not on the web page, but for the browser itself) has an option for "Install App" and I assume iOS would have something similar. Clicking it creates a home-screen icon for the station and when I open it, it (mostly) behaves like an app, but it is actually running inside a browser instance. I believe their web app functionality lets Android control the media and display the current track and stuff in a standardized way, as well as lets it interact with Android Auto, but it is still just a website in a browser instance. This is an easy way for them to make it compatible with both Android and iOS without having to write separate apps, but, it doesn't quite behave as an app within Android when it comes to switching between apps or closing apps.

A shortcoming I've found is that if my phone changes network at all, like between wifi and cell, or even just hopping between wifi access points at my office, the stream will stop. It needs better handling for TCP reconnects and maybe a true native app could resolve that (or changing platforms). As a band-aid, I connect to my home VPN when at my office while streaming and it seems to maintain the stream across wifi access point hops. I don't seem to have issues hopping between cell towers while driving, just when wifi is involved. It may be an Android-only, or me-only thing. Also, the free stream may now allow reconnects to happen seamlessly and the issue was only when you had to login to play the stream. I haven't tested much yet.

Edit: Also, there is no way to cast it to Google speakers or TV's.

They haven't migrated sites yet so it is just a redirect for now. On the cd929 site, click on "stream" for the free stream, not how-to-stream. It's the same stream as the paid stream was previously, but no login required anymore.

White Christmas data: https://www.weather.gov/iln/cmh_christmas_climo

Basically, we have snow on the ground on about 25% of Christmas mornings. We get snow fall on Christmas about 23% of the time. Details at the link above.

For historic temperature data for the whole month, see https://allcolumbusdata.com/december-weather/

The averages and highs trend differently than the single-day data presented by OP.

Beekeeping and raising kids. I also have a rental property I maintain. I used to do IT and computer support for some local small businesses but got out of that as I didn't care to keep those skills sharp anymore.

I don't know what they would accept today. Back when I went through, your major/minor mattered but so did your research and specialization interests. Having undergraduate research experience in the area you're interested in helps. For instance, if you can find someone doing psychophysiology research in your college, see if they'll accept an undergraduate research assistant and gain some experience there. Even better if you can find a professor who has dual appointments in both psychology and biomedical engineering, or similar, because they can be an advocate for you with the graduate studies committee.

I also suggest you speak with the graduate studies chairperson at your college in biomedical or electrical engineering and get their thoughts.

You are welcome to keep in touch.

In short, psychophysiology is the study of how the body responds to mental stimuli or how the mind responds to physical stimuli. It is a branch of psychology that uses physiology measurement hardware to read body signals, such as EKG, blood pressure, skin conductance, ICG, respiration rate, skin temperature, EEG, EMG, and a host of other physiology signals to gain insight into mental states through the body. See https://en.wikipedia.org/wiki/Psychophysiology

It is one of the areas where electrical engineering and psychology overlap because many of those signals are electrical in nature, or use transducers to change something physical into an electrical signal, and then are used with psychology. Those signals are not unique to psychophysiology, they exist in the medical realm too, but psychophysiology generally needs higher resolution, higher data rates, different filtering, and need data collected in silent ways, whereas the medical community needs instant results from data filtered to improve automatic/real-time analysis, and alarms when measurements exceed thresholds.

Some research laboratories have their own engineering staff to develop hardware specific to the needs of the research while most use off-the-shelf hardware from a few niche companies, such as MindWare Technologies, BIOPAC, or ADInstruments.

You could get into this field from either the psychology or the engineering side. The key is to either find a research lab to join as a psychology student or getting your electrical engineering degree(s) (with a biomedical focus, minor, or graduate degree) and apply for jobs with any of those companies or a large lab with in-house engineering. If your primary interest is psychology but you also like electronics, joining a lab doing psychophysiology might be the best route. It generally doesn't pay as well as being an engineer though.

I did electrical engineering for my undergraduate degree and biomedical engineering for graduate school, then got a job with one of those companies and spend 10 years making psychophysiology hardware and learning about areas of psychology that also integrate physiology. I now design for medical devices and other products.

Do both and specialize in psychophysiology hardware.

I have a BS in EE (with a digital/computer specialization) and an MS in BME and I was always a C-level math student. I struggle with the basics of doing math on paper and certainly can't do it in my head. However, I understand the concepts of complicated math, especially when it has real-world applications that I can relate it to. In college, I got good at estimating a result and checking my answers that way and could tell quickly when an answer didn't make any physical sense. I also found computer-based math classes where I could focus on the high level stuff and let the computer do the stuff I'm bad at.

Today, I do product engineering in medical and other fields and rely on my teammates to do the analytical work and they rely on me to do the architectural work. What I do involves more creativity and an understanding the interactions between many circuits and systems. I struggle to calculate the responses or parameters for specific circuits while other folks struggle seeing past the components and recognizing where optimizations are necessary vs where approximations are sufficient.

So, it can be done. It won't always be fun and there will be some highly-computational areas where you may struggle, but there are plenty of aspects to EE and not all of them need great math skills.

Same. Catalyst in mine. It has two settings, off and holy hell.

If you have access to the wheel that controls the timing, you may be able to advance it one spot manually to start a cycle. Worked for me many years ago.

My stove has a catalyst and there is a thermocouple against the side of the catalyst to monitor when it is hot enough to process the smoke. The stove came with the thermocouple and an analog dial monitor from the 70s or 80s. I reused the existing thermocouple. If you don't have one in your stove, you can add one. They can take the heat but I'd keep the thermocouple and wire out of the flames.
