New Beginning

28 March 2019

Perhaps.

Google Plus was taking up a lot of my “free” time, but now it’s going away as of 2 April 2019. Already, there are perhaps six or so people left of those that I was following. As people left, and left directions where they went, such as MeWe, Facebook, and so on, my thoughts turned more to my blog.

Thinking about the blog and the potential for writing more there, I was surprised to see that my last blog entry was apparently 2018-10-24 and here it’s already 2019-03-28.

As a result of Google+ shutting down, I’ve been thinking a lot lately about the point of my G+ participation. Sure, for a while I was sharing pictures, but I’ve drifted from that activity as well. I blame the Idaho weather…whenever anything interesting was happening in the night sky, we usually had bad weather. Clouds, rain, snow, whatever. Enough that I’d use that as an excuse to not be able to post images.

I’m thinking how I used to enjoy writing here on my blog, sharing my stuff. Sure, I had enough followers to be able to count them on one hand, but what was I writing for, anyway? Like any human, I’d like more followers than that, sure. “Not going to get them if I don’t post,” I know that very well. Nor if I don’t put word out there about my posts, and there’s the conundrum. Originally, G+ was part of my method of putting word out, but it slowly became my blog replacement. Twitter was the other, and I’ve not been on there in years other than an automatic post when I blog.

So, what now?

Do I migrate to MeWe? Return to Twitter? Start hanging out in Pintrest? Somewhere else? Definitely NOT to Facebook, there’s no way I’ll ever have an account there. I could argue that moving to another social medium gives me the chance to study other people’s astrophotography and learn what settings and setups they’re using, but that doesn’t push me to get out and shoot my own images. Or to actually work on my own post processing.

Then there’s the site itself. I’m thinking of redoing it a little. Not drastically, I actually like this layout. Just remove old stuff, remove the Pa’adhe stories, the short stories, the poetry. Perhaps wipe out all my past posts and truly start over? Maybe just focus on writing about my explorations, photography, and ham radio. Outdoors and technology? Music? Long indeed has it been since I did anything with music.

I don’t know.

It all seems futile now. Well, maybe not futile, but pointless. Just something to do to toss away time. On the other hand, if I didn’t ramble so much in my posts, but kept them to just those three topics, maybe it’d be more focused, more useful to the wandering passers-by? People don’t seem to really care about any of my ham radio posts, so I could just focus on the other two, exploring and photography.

I feel like Scrooge early on: Bah, humbug.

So…what’s with this new beginning? Do I or do I not, that is the question.

Update 10.10.2018

24 October 2018

It has been a while since I posted here…once again. I don’t know why that is, but it certainly hasn’t been for lack of anything to post.

Photography-wise, most of my focus lately has been on my old 400mm Tokina. Getting it into sharp focus seems to be an almost impossible task. “Almost” because I refuse to believe it is impossible. For the longest time, I’ve been trying to get “focus trap” to work on the lens with the Pentax K3. No matter what I tried, it just wouldn’t work. It worked with the K10 and *ist, so it was frustrating not being able to use that method.

Then I came across something on the internet that made me search with some terms I would never have thought of using. Sure enough, it turned out that with the K3, Pentax created a setting in the Custom menu to allow or disallow that. Not only that, the name of the menu item, at least to me, isn’t intuitive. Sharp Capture. In hindsight, the name does make some sense. So, now I have the ability to use focus trapping.

Even with that, though, it’s still not locking in with the sharp image I remember. Note to self: put the 400mm on the K10 and/or *ist and verify it works like I seem to remember.

I think ,however, that there is a slight difference where the focal plane is compared to the K10 and *ist bodies. That doesn’t make much sense, but right now it’s the only answer I have. Even with the other manual lenses that I remember working properly on the other two bodies, I have to focus past the subject to get a sharp image.

Right now, my plan is to combine focus trapping with the multiple shot mode. That way, when the focus trapping triggers the rapid sequence of images taken while still adjusting focus manually should hopefully include at least one image in which the image is sharp. Or at least sharpest.

We’ll see.

Well, that idea of focus trapping plus multiple shot mode didn’t work. I guess I’m going to have to try and find another way to do this.

The ham radio arena is the next area to bring up to date. Here, the use of the straight key for Morse code as my computer input keyboard has indeed taught me most of the characters. BUT that only taught me to transmit. Recently, a ham who agreed to be an Elmer (aka Mentor) for me sent me a simple device that activates a LED to the tune of the dits and dahs of Morse code.

I bring that up because once I got this hooked into my radio and everything tuned, I had a chance to actually see some Morse via the LED. I was able to, for the first time, clearly and without any of the usual difficulties of differentiating them, see the Morse code. And that segues nicely into I was able to see the dah-dit-dit but I had absolutely no idea what dah-dit-dit stood for. I actually needed to mentally imagine sending dah-dit-dit with a straight key before I could make the connection to the letter D.

And so I found out what I was afraid of actually happened.

I can now transmit a lot of the characters without even having to think about their dit and dah components. The reverse, however, is not true. I could not decipher that visual representation with the same ease I can send it.

Oh, boy.

Now I’m going to have to add a LED to the straight key I use with the computer. There’s a LED on the Teensy board that flashes as I key the characters but it’s under the board holding the key and not visible. Rats! That would have been a perfect solution.

At least it’s a relatively easy fix and since the onboard LED already flashes while keying, I can use that same pinout, so no code modifications needed. I just have to figure out what color LED to use.

Writing. This is where I hang my head in shame.

I’ve done some editing for other authors, but I’ve done precious little writing of my own. As I mentioned last time, I did start a new Pa’adhe story, but nothing past the opening scene and setting up the tale. I have a reasonably decent story for this one, and it’ll provide the backstory for Scarle, but just sitting down and writing just hasn’t happened. With any luck, writing and posting this will get me going on it.

Unfortunately, I’ve been spending a fair bit of time programming. Unfortunately because otherwise I might have been writing instead.

I bought a cheap 3.5” TFT LCD display that came with NO instructions or paperwork at all. It took me several months to finally locate what seemed to be the same display being sold by another vendor with tutorials and examples. So, that’s now up and running on one of my Arduino Unos.

Plus I’m waiting for a part for a 2004 display (20 chars x 4 lines) so that I can use IIC protocols to program it for use with ham radio. This will be a potential display for viewing and decoding Morse code that comes over the air to my radios. It’s intended to just plug into the headphone jack of the radio and display the detected audio and Morse. Eventually I want to modify that to provide the option of showing, selectively, the following: (1) a bar graph or “LED” display of the dits and dahs, (2) a string of dits and dahs such as …. . .-.. —, or (3) the actual translation of the code to display HELLO. Maybe even other modes, although at the moment those three seem to cover all bases for me.

UGH! That’s enough, this is already longer than planned and there’s more like trips. I’ll save those for another time.

I’m Back! I think.

26 January 2017

Well, this is odd. It’s been a bit over a year, I think (too lazy to look and see for sure) since my last posting here. On top of that, this particular post isn’t necessarily my standard fare. It’s probably a mix of rant and quick updates. All ranting is my personal opinion, of course. No pretty pix, those will come later.

So, which first, the rant or the updates? Ah, you figure it out, they’re all mixed together.

Photography wise, it’s been a bust, between building the Vardo (done!), Idaho weather, my dad, and other stuff, I’ve not actually gone out “to do photography”. I’m working on that, though, and you can expect some more pictures this year. Time lapse. Video. Landscapes. Macro. Whatever grabs my attention at the moment. And yes, I did indeed say video, that wasn’t an error.

I’ve written a small script, more a proof of concept idea than anything else, that I plan to video. If it turns out good enough, I might even look into YouTube. My granddaughters want me to start putting my videos up there and I’m tempted. If this project works, I probably will start putting a couple of older videos up and create more. I never expected to get into or enjoy making video but I find I do.

Don’t expect much in the way of audio on my videos. I’ll try and include music based on the input of other people, but I have a beef with the lousy captioning on YouTube and am going to extract my revenge by including captions and no voicing. So there. I swear, I never know whether to laugh or cry when I see the automatically generated captions on most of the YouTube videos. It sucks. The only ones any good seem to be those that go out of their way to include captioning themselves.

This next video project is showing me a bunch of stuff already, and I can’t get out to the Owyhees to film it. Film it…video it…whatever. I have a DJI Phantom 4 and that’s what gave me the idea for this video. Next up, I needed a video recorder that could become your eyes, so I wound up asking around and borrowing a GoPro Hero 4 Black. The video specs for that match well with the video specs for the drone, BUT the Hero 4 is a fixed fisheye. More on that later.

The Hero 4 has no playback capability and the only way you can get any kind of immediate feedback or live feed, is to use their Capture app. Or a third party one. And guess what? Those idiots at GoPro seem to think you absolutely need to log into their servers before you can get any use out of the app. Yeah, right. Waaaay out in the middle of the Owyhees, where I set up for my video on the GoPro and test it, where there’s NO cell service? How in Hades am I supposed to log into their servers from there? Stupid and pointless. However, I did manage to find an older Capture version and that one lets me have live feed and control over the camera to change settings WITHOUT having to log into their freaking servers first. Those of you out there wanting this…look for the newest version prior to 3.x. It also has the older logo. Just be sure and don’t allow your apps to automatically update or it’ll get replaced with the new one. You’d think losing their market share would warn them and that it’s logical that if you want to keep your fan base, you shouldn’t push out an upgrade that makes it impossible to use the app where there’s no service. Especially for a camera intended for extreme stuff out in the middle of nowhere. I guess common sense isn’t part of the job requirement there.

Now about the GoPro fisheye situation. For my wants, the fisheye gives me a great wide field of view, but it does have those pesky fisheye effects. You know, the curved  vertical and horizontal lines that should be straight.

To remove the fisheye effects, there are plenty of tutorials and apps out there. The first I tried was the GoPro PC app. Posts, reviews. blogs all say it has a built-in fisheye fix that’s good. Guess what? Yup, you got it. It, too, requires a server login. Forget it, I’m not gonna look for an older version of that, too. That made it easy to uninstall and discard with only a second or two’s thought.

I moved on to four programs that I already have. I’ve restructured my home systems so I have a laptop that’s just for photography work. On that machine, I have Linux as my OS: Ubuntu Studio. There are some things I don’t like about the OS layout, so I may just migrate to a clean, minimal Ubuntu 16.04 and have only the video and graphics programs that I find work for me. And yes, there is a point to mentioning this.

The four programs I was looking at for the fisheye removal are: Adobe After Effects (Win), daVinci Resolve Free (Win), OpenShot (Win/Linux), and Kdenlive (Linux).

OpenShot was the first I looked into, and while it’s a nice basic editor, it was taking me too long to find out how to deal with the fisheye effect so I dropped that approach. I then went and played with After Effects and it did a reasonable job, but the file size went from 357 MB to 12 GB. HUH? OK, I figured that was user error and I could set the parameters better later or transpose to a different format. At the same time I was playing with After Effects, I was messing about in Kdenlive. That one was not only easy to deal with the fisheye, but it had a couple different ways to do so. After I got done trying After Effects, I then looked into daVinci Resolve. This was just as easy to use as Kdenlive but the free version is apparently time bombed or has a file size or video length restriction. Unlike last time I used it, this time it slapped a watermark on the entire video. I’m going to look into that, but if that’s the case (time bombed or file size) then I’m going to toss it.

So, looking at the various outputs, I was rather surprised to find out that the best resulting corrected video came from my Linux machine: Kdenlive’s Defish filter. Not by a little, but by an easily noticeable difference. File size, quality of resulting video, quality of corrections…Kdenlive was the best. daVinci Resolve was the next, but it had a huge file size as well. That I expected, though, as Resolve doesn’t output the final video, only the feed into the conversion. That I could live with. To be honest, though, when I started looking at these I really didn’t expect the Linux program to come out ahead like that. That was a very welcome bit of support for my Linux love.

I’m going to take a look at PiTiVi (also Linux) later and see how it compares to Kdenlive, but going forward right now it looks like for my project I’ll be using Kdenlive as my editor.

On the writing front, I’ve been assembling an ebook with the various tales of the Pa’adhe. It has a cover for each story plus the ebook itself. I need to create three more covers, so I’m waiting for the weather here to get better so I can go get the pictures I need. We’ve busted the local records across the board for snow this winter. We got more than the winter of 1985, and that was on the ground only about two weeks. This winter’s snow has been on the ground for over a month now, and it’s been piled high. Buildings have collapsed as a result of the amount and type of snow.

I’ve sure enjoyed my first year retired, but funny enough, I sort of seem to be way more busy than when I was working. And I’ve still not gotten back into my radio stuff. Maybe this year!
