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!

A Return to Camping

20 August 2015

It has been almost since my kids were born, around 35 years, since the last time I’ve actually done what I would call camping. I’ve been out and spent the night in a tent or in the car, as you’ve seen in my other posts and pictures, particularly the astrophotography posts. But it’s been decades since I’ve actually gone camping as in the family going up in the hills and spending the weekend in a campground.

That’s what we did this last weekend. And that’s when I discovered just how much I missed it. The really cool thing about it, though, is my wife even said how much she enjoyed it. That gives me even more motivation to get the Vardo done.

So, on to the camping….

We left Friday morning and headed up, planning to go to Warm Lake and stay in one of the campgrounds there called Shoreline. We stopped at the gas station south of Cascade to get some treats and so found out about the Cougar fire in the area. For those unfamiliar with “Cougar fire” and the like, fires in the US NW are usually named after a creek, mountain, or other geographical landmark in the area and this one was named after Cougar Creek. We called the lodge for a status, discussed the situation and decided to go on in to Warm Lake if we could. On the way in we saw some side roads off Warm Lake Road that were blocked off, including one with the sheriff sitting there to keep people out but still keep it open for the firefighters to access the Cougar fire.

The Shoreline campground was full when we got there, which didn’t really surprise me. Around here, during the summer, unless you reserve a campsite in advance, some places a year in advance, it’s hit or miss whether you’ll be able to stay in any particular campground. However, we had noticed a really nice campsite along the road to the campground, and wound up staying there with room for all of us in “one” spot: my daughter’s family (7), my son’s family (4), my sister-in-law and one of her sons (2), and my wife and I. Fifteen of us in one camper and three tents, as you can see in the picture below. No services, just campsites, but it was a few minutes walk to the lake and outhouses and water was available at the lodge just a few minutes away by car so it was really pretty convenient. Happily, the temperatures were cooler there than at home, as well.

We set up a canopy over our tables near the firepit and that served as our kitchen for the weekend. The firepit was our communal center. And of course, we had a hammock to relax in, when we could get the kids to quit playing in it.

Shows the yellow canopy we set up over the white camp tables with my daughter and her husband by them and my wife in the hammock in the foreground, playing a game on her phone.

The kitchen and the hammock.

Naturally, since it is camping after all, both nights had campfires and S’mores. We also cooked a few trout and hot dogs over the fire. One of the funny highlights was when my nephew roasted six marshmallows on his trident and crammed them between full-sized Graham crackers on top of a bar of Hershey’s Chocolate. Boy, was that one huge, messy S’more! I wish I had a picture of that to include here.

SHows a little red flatbed trailer, 4' by 8', with wooden side rails behind a blue Geo Tracker. Grey tarp creates a dome over the rails to provide a sleeping area.

The little red trailer rigged for sleeping in.

We even managed to jury-rig a small “camper” out of a utility trailer, some tent poles, and bungie cords. For a cot we had a reclining camp chair. The railing at the back was removed to provide access.

We had a blast! It was a really dusty campsite and also smokey from the Cougar fire two to three miles west of us. Because of the fire, either a sheriff or firefighter would come by each evening to advise us of road conditions. Friday night, the sheriff said we didn’t have to evacuate, but he wasn’t sure that he would personally remain camping in the area. We discussed that and decided that if we had to leave, they’d come by and let us know, so we stayed put. The next evening we learned that the fire had jumped the road and so the road was currently closed. The next morning it was opened up again, so even with the fire related conditions, we actually had a really good time and no problems getting back out Sunday afternoon.

Dutch oven cooking was supper Saturday. My son fixed up a chicken stew around noon and we maintained coals and fire throughout the day.

Also shows other 12" Dutch oven in coals to side of fire pit. Chairs in background around the fire pit with the little red trailer and Geo Tracker in the background.

Field assembled tripod with proper lashing at top and a field made hook for the Dutch oven and coffee pot to hang from.

This was the first time in about 50 years that I made a tripod and only the third hook I made. It worked really well and we even used it for coffee in the morning. We did have one problem with the Dutch ovens that we initially blamed on the tripod: the bail on the one hanging from the tripod apparently got pulled out of shape. We couldn’t lay it over and just lift up the lid, we had to slide the lid out the side. Later, when cleaning up we discovered we’d swapped the lids when we prepped and put the food in the Dutch ovens. When we switched the lids, the bails on both ovens worked just fine. Now we know what to check next time.

Playing in the lake, Saturday, I discovered muscles I hadn’t used for decades. For that matter, I only survived three swings on the rope before I was afraid I couldn’t hang on for the next one. Come the next morning, I found I had sore muscle under the sternum and my underarms. It was a good feeling, though, and made even better when I realized I had gained back another notch in my belt by the end of the weekend.

Rocky ground with a big crack in the rock. Red Bocce ball in the crack.

That was NOT where he wanted it to stop!

One of the games we played was introduced by my nephew: Cross Country Bocce. We only played to 5 points per game, and we got a real workout. The rules were simple: start from one point and the person going first throws (yes, throws, not tosses!) the little white target ball anywhere they want. Then he or she throws his Bocce ball (one per person playing) to try to get closest to the white ball he just threw. Then the person that threw the white ball has to go find it and point out to the rest of just where the white ball was. Sometimes we could see it on the ground, but a lot of the time we couldn’t and had to try and guess what was there to deflect our balls into the right spot. Whoever gets closest (and sometimes that’s a couple of feet or more away) gets the point and throws the white ball for the next round. Repeat until someone has 5 points. With all the rocks and trees, there was no guarantee that the white ball or your Bocce ball would go where you aimed. After all, that little white ball fits between trees better, for one thing and bounces off rocks more. So we were up hills, through brush, on the road, and watching our balls roll or carom all over the place as we tried to allow for slope, rocks, trees, bushes, and so on.

Little target ball and several red, blue, yellow, grey Bocce balls on the ground around a tree. Ground is covered with twigs, sticks, rocks of assorted sizes.

One of the very few times most everyone got to the white ball.

The above is one of the few times most of the balls were clustered around the white ball. It is a picture of the type of ground cover we were playing in, too! One of the throws of the white ball was hilarious: It hit a tree, bounced off to hit a tree close by, bounced off that second tree back to the first, rebounded back to the second, once again off that back to the first…I think there were five or six bounces between the two trees before it fell to the ground. Kind of like a Japanese Pachinko game, I think. There were many more hilarious throws, too, but this one was particularly funny.

Shows my son bent over his son's shoe taping the front half back together with silver duct tape after he walked the sole off. Granddaugther stands to the side watching.

Thank heavens for duct tape!

We had at least one casualty that required major treatment. Fortunately, there was some duct tape to hand and we were able to properly ensure the continuity of the weekend. As a matter of fact, when we left for home the next afternoon, this shoe was still going strong after playing all over the place in the rocks, hills, sticks, and riding bikes.

Like I said, we all had a blast and we’re looking forward to more camping. I’m eager to get the Vardo done and get out camping with it.
