It’s the Apple WWDC!

I’m not quite as interested as I’ve been in years past. But I’ve got laundry running and vinegar in the drain traps, (I prefer that to caustic chemicals due to the septic system,) so I’ve got a while before I can go anywhere.

I should probably make a grocery/dog treat run but neither are critical so It’s not going to matter if I put it off a day.

I’ll turn on the WWDC in the background. I’m curious about the new features coming in the latest versions of Apple operating systems. Since my iPad, watch, and computer are all less than a year old there will be some relevance to me.

I’d have upgraded my phone but I really like the blue color and the Purple from last year was not attractive. For some reason I don’t want to go back to space gray on my phone. It’s shouldn’t matter since my phone is usually in a case, but when I’m around the house it’s not unusual for my phone to be naked. (Okay so my phone is a slut! Who cares?) perhaps I’ll upgrade my phone in the fall or maybe I’ll wait another generation. By that time the phone will be 3 – 4 generations old, the battery will be on its last legs and maybe Apple will move everything to USB C so I can toss all the Lightning cables.

I liked the additions to the various OSs. I can see using some of the newer features frequently and how they’ll make my life easier. I really liked the improvements to the Hiking app on the watch. I also like the idea of having the health app available on the iPad. That should make evaluating the data a bit easier with a bigger screen.

The larger MacBook Air is interesting too. Especially since it’s got the M2 chip, the ability to have a ton of memory and storage, and an 18 hour battery life. That makes that particular machine probably the hot ticket coming this fall.

I have to admit that I’ve been interested in the Mac Studio since it’s debut. I didn’t go that way because I like having a laptop.

However, the power of the new iPad Pro with an M2 chip is astonishing and I could see using the iPad as my only portable computer, then having something like the Mac Studio if you needed a real powerhouse when you got back home.

This is especially true since Apple Logic Pro and Final Cut run on iPad now. There are a lot of other “standard” office applications that run just fine on iPad but it you needed video or audio you had to go outside the Apple ecosystem. Those barriers are gone and honestly my M2 iPad Pro is about as functional for my needs as my laptop. I could see the iPad / Studio blend now.

I wasn’t all that interested in the AR thing that’s been rumored for such a long time. Now that I’ve seen it, it’s as expected, very expensive.

That being said, I can see the potential. I can even say I’m interested enough that I’d like to see it live and in action.

If it worked well enough, I could see it replacing TV screens for those folks that live alone. I’ve considered that possibility with just my iPad and Mac. Then again, I don’t watch cable, or broadcast TV so I might be an outlier case.

Come to think of it, I haven’t to my knowledge watched any TV using the “new” (10 years old now) digital channels that are coming from broadcast stations these days.

I literally have no clue how that works. I’ve not lived anywhere that digital channels received via an antenna were available. Even the Escondido apartment was in a “Signal Hole”. It didn’t matter too much since the cost of internet only was higher than the cost of internet and cable TV combined. Talk about desperate to keep TV subscribers! I honestly don’t recall watching anything on TV for three years. I’d watch something on a streaming channel or a movie on DVD.

That was probably due more to my weird schedule, than the quality of TV. I got home from work about 2PM and was in bed by 7 or 8 PM. So any TV I could watch was talk shows or soap operas. Other more interesting dramas were on way past my bedtime. I didn’t pony up the cash to rent the DVR feature on the cable box.

I gotta say, having a virtual screen that you could make a big as you wanted without needing a sound system for surround sound might be a slick way to really enjoy some movies.

The price tag of 3500+ might be off putting.

I did like the use case Apple showed where the lady was on a full flight and tuned out the plane and other passengers entirely.

Hell that could make flying bearable again!

Hmmm, Getting the first data about energy production from the Solar Panels.

IMG 2474

Yesterday was the first full day of Solar Panel operation. The panels themselves went online Nov 30th about midday.

The website and the mobile application provide pretty nice insight into the system status. What’s very cool is that I can see individual panel production and therefore can see if a panel is having trouble.

I’m figuring that we’ll run for several months before deciding if the system needs to be tweaked or if adding battery backup would be something useful.

One of the things that was befuddling me when we got into this, was that a solar array of interconnected panels would only produce power skewed to the lowest common denominator. 

In other words, the laziest panel on the roof would drag all the other panels to its level not the other way around. When I was a kid playing with Radio Shack solar panels, this effect really annoyed me. I kept adding panels to a small array but the voltage never increased above the output of my oldest little panel. Oddly and very confusing to my little child brain taking that oldest panel out of the circuit, then measuring I’d see the best output from the next lowest producing panel and so on.

I could see the pattern, but couldn’t explain what I was seeing. I hadn’t really thought about it until we began this project.

I’d seen a similar effect with my portable panels while recharging battery packs, but it was so negligible in that application that I’d just shrugged and moved on to something else I was doing around the house. In that case, either way, the battery pack would be recharged in 3 or 4 hours, so the impact wasn’t a big deal.

When you’re talking about a large array on your roof that’s costing you money and it’s supposed to lower your electric bill you kinda want to know these things. Well, at least I do.

I was really confused on Wednesday, when I got a look inside the “Controller box” mounted on the wall of the house. I was expecting to see a D/C (Direct Current) to A/C (Alternating Current) conversion device, but what I saw instead was more or less standard A/C connections and breakers.

The mystery deepened, I did see a coil of the type that’s used to detect current flowing through wire. In fact it had a single wire running through it. That wire went to a grounding block, the coil itself was connected to a small digital circuit board mounted at the very back of the controller box. This board was in no way going to be capable of handling the kind of power that could be coming from the panels on the roof. Looking at it, I thought, “That much power would turn that board into a burnt green popcorn kernel.”

The mystery deepened. The installer had no information about the details. He was just finalizing the A/C hookup to the house. But I saw inside the Controller Box, a makers logo.

“To the Internet, Boy Blunder!” Yeah, as a kid in the 1960’s I watched “Batman” and I read “Mad Magazine”. What of it?

When I got to the manufacturer’s web site. All was revealed.

Turns out, each panel has its own inverter attached to it. Meaning the D/C to A/C conversion is done at the panel. As I read the specs and dug into the installer side of the website I sat there going, “Duh!!!”

The design is brilliant. Since the power coming from the panels is already A/C it’s just a matter of connecting the array to the house A/C (with some safety features of course,)

Electricity flows a lot like water. If there’s more electricity coming from the house then it flows back into the grid. This is a gross oversimplification but it’s easy to visualize.

Since the D/C to A/C conversion is done on panel, each panel can produce at its own rate without the other panels affecting it, or it affecting the other panels.

That mystery was solved, so what is this controller doing? 

It’s talking to each of the inverters on the panel, and then sending that data to me, and sending it to the installation company so they can address any warranty issues and they’ll know if a panel needs servicing. It also allows accounting. Since the system knows how much power each panel is producing, and therefore what the array is producing the Electric company can’t get away with “fudging” the numbers about credit owed.

The Controller monitors how much power we use, how much power is produced, simple math calculates the difference. It’s the difference that gets sent back to the electrical grid for the power company to “purchase” from me as an electrical producer.

The Controller also provides for the addition of battery backup, and would manage a switchover if needed due to a power failure.

Another thing I didn’t realize was that if the main power goes off and I don’t have a battery backup, I’ll still be without power. 

I understood that I’d be without power if a power failure happened at night, but I thought if the power was off during the day, I’d still have my fridge and essentials running. That’s not the case.

Thinking about it it makes sense. It’s a safety feature. If I’m generating power at my end and feeding it back into the main electrical grid, then the electrical linemen could never work on the power lines. The lines would always be powered up until each house with solar panels was physically disconnected from the grid.

The Controller box handles that automatically in the configuration I’ve got installed.

I’m thinking that a battery pack is probably in the future.

I don’t want the hassle and noise of a gas powered generator running during a power outage.

When the inspection was finished, the solar guy pulled off the protective plastic on the controller box and voila the manufacturer’s logo is now visible. 

I knew I shoulda peeked under that protective plastic film. I’d have been able to have my questions answered a lot sooner!

Now I just have to wait. A couple of months of runtime data and I’ll be in a better position to decide if I need to add a couple of panels and what size battery pack I’ll need to install. 

I’ll also need to figure out if making those modifications will add to the overall value of the house if I decide to sell it.

I also suspect that if I leave California, where-ever I move to, I’ll be installing Solar probably with batteries because I like the idea of being able to sail through power outages without really noticing them.

I don’t like to be inconvenienced!

Call me a snooty, spoiled, first world person if you like!

I just noticed there are 1600 blog posts here.

Wow, I hadn’t been paying attention.

I’ll grant you not all 1600 are worth reading. Generally they’re pretty Hit and Miss.

Sometimes I’ll hit on something that strikes a chord though.

Here’s a short story from my library

Here’s another short story

One consistent favorite is called Night Rain

Surprisingly, this post about excessive regulation has been getting a lot of hits in the past month.

Everyone’s favorite about AT&T is always near the top of the “Popular List”

My view on Busybodies has also been trending lately.

There’s a lot more here, but these are probably among the best of the bunch.

Feel free to browse. The Tag list to the right hand side of the page is up to date for the more current posts. However the Category List at the bottom of a post will lead you down the rabbit hole to older posts.

One of these days I’ll decide to convert the Category list completely over to Tags and then everything will be fully in sync.

Enjoy yourselves and take these posts with a grain of salt, or in some cases… An entire salt lick.

Be Well.

Great work if you can get it…

Recently the local pharmacy informed me that a routine maintenance medication Rx had expired and that I’d have to see my dr. to get it refilled.

Great! Another expense that I didn’t need. Aside from the gas and the time that I’d be sitting in the doctor’s office I was worried about the hassle of getting blood work and all the other annoyances.

I put it off.

It’s not like I’m afraid of doctors, I just hate the inconvenience! I do a lot of self monitoring and do it with higher quality devices. If something seems amiss for a while I’ll typically “Man up” and go subject myself to the hassle of seeing a dr.

Case in point, the ripped open thumb joint of last summer. That’s 6K I needed to spend like another hole in my head.

I’ve got a bit of a cold, I don’t feel like doing too much today so I thought, “I’ll be productive and make the doctor appointment before the day gets away from me.”

Grabbing the phone and dreading the hoops I thought I was going to have to jump through I made the call.

Much to my surprise, they had a Telehealth system. Huh, I was especially surprised when the cheerful girl on the phone said the doctor could see me in half an hour and that he was running on time.

What? I can be seen in half an hour? WTF? That’s one for the record books. Where is my 1 month wait? I’m used to having to sit in a waiting room full of sick, broken people. You mean that I’m not going to have to endure that?

The world has truly gone mad!!!

Sure enough, a link shows up. I click on the link and there’s my doctor. He says he’d like to see me in person for a physical with some bloodwork in hand, whenever that’s convenient. He reminds me that it’s been over 10 years since I had a colonoscopy and that I should probably get that done.

He asks how I’ve been and what my last BP reading was. I tell him this mornings reading. He’s like that’s fine. He asks if I’m running a fever due to the cold. I tell him yes but it’s only low grade. He’s says, “Good, keep an eye on it. Take care of yourself and I’ve renewed your Rx. Call me if you need me, I’m gonna go deal with some really sick people.”

I laugh, we sign off and that was that.

I guess there’s benefit to me doing the self monitoring and having the data on hand. There is also the probability that he knows I’m pretty diligent about keeping data and know my body.

The cost was the same as a regular appointment. So it doesn’t hurt his bottom line. The advantage for him is that he isn’t exposed to a bunch of sick people clogging up his office.

I did the math. He’s knocking down about 1 grand per hour doing Telehealth appointments.

Great gig if you can get it!

I can’t complain too much. I didn’t have to drive an hour to see him for a 10 minute appointment, nor did I have to deal with masks and all the attendant BS of walking into a medical complex. Here I am, unshowered, unshaved, in my sweatpants, and I was able to take care of business from my couch.

It was painless, and convenient.

Next time… I’m taking the call in the nude and scratching my balls. I gotta have some shock value when I see a doctor!

Based on a sample of one time. I’d say if the opportunity arises give the Telehealth option a whirl.

It’s kind of an interesting take on the original house call. Back when doctors where country doctors who often saw their patients into, and out of this world.
