Slowly, slowly

8 June 2017

Still not in a writing mode, but working towards it. As far as that part of my life goes, I’ve been working on the Pa’adhe ebook. It’s been mostly proofing (found a couple of errors), layout, making sure things are in the right order. I’ve got three cover pictures left to do, still: one to replace an existing cover I don’t like and two for the stories that don’t have a cover yet. The designs are done, but now I have to figure out what pictures to take and combine for these covers.

Talking about pictures, I’ve also been working on three photography projects. Actually, it’s probably more accurate to say two videos and one photograph.

The photograph is a three generation portrait that I’ve been thinking about for several months. Now that everyone’s present that needs to be in it, I can proceed with actually taking the photo. I’ll be using the DJI Phantom 4 for this due to the perspective needed and to avoid any part of the photographer being in it. It’s also necessary to use the drone to achieve the hidden geometric aspect I have in mind.

One of the videos I have mentioned before. I’ve a script written for it and have all the necessary gear to do the shot. What remains is to get the necessary actors together on location (herding cats would be easier) and get the video needed so I can get to work compiling the whole. This I need to get done within the next two months or it’ll be unlikely to ever get done.

The final video is one that I am not even sure is going to be anything more than an experiment. Fundamentally, it’s one of my granddaughter dancing, but it’s the perspective that makes the video what it is. Or breaks it. I can see in my head what I want to achieve, but until I actually start processing the video, I have no way to tell if it’ll work or not. In some ways, it’s abstract…but without being abstract. I’m trying to explain to some extent the problem with the visualization without giving too much away yet and that’s not easy to do. With everything else I can throw out teasers, but this one…any teaser is too revealing. Let’s just say that if I don’t get the angles right, it’s not going to work and since there’s nothing like it out there that I know of, I have no guidance to the right angle. If it’s off by even a little bit, the impact won’t be there. Even so, right angle or not it could still be a bust.

Both videos will utilize the GoPro Hero 4 Black and the DJI Phantom 4, though in different ways. I never did think I would be doing video, but there it goes. Never say never.

I’e been doing a bit of amateur radio, just PSK-31, since my last blog post. I have to admit I’m happy with the home station, but not so much with the mobile setup. I need to do some more playing with the mobile gear to figure out what’s not working, but it’s also quite possible that it’s simply there was no activity when I was using it. Or maybe it was a bad location. All I can do is keep trying different locations for a while before I start troubleshooting the gear.

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 Update

5 March 2015

It has been a weird beginning to the year for me.

I fully meant to return to this blog well before now, but somehow writing for my blog just wasn’t a priority. From time to time, I’d think of something to write about, but I just never sat down and actually did so.

From an amateur radio standpoint, I’ve been working to develop something I refer to as The Thumper. It’s based on something I read about in a blog post where the ham described his fondness for CW (Continuous Wave, aka Morse Code) and an on-the-air experience meeting a group of deaf learning ham radio and cw. The original Thumper was mentioned only in passing, and described as “a device that attaches to their forearm and taps them to indicate the Mose Code being received.” I have various issues with LED displays and my current tactile transducer setup leaves much to be desired. For The Thumper, I’d started by utilizing an Arduino driving a RC servo and while that does work to an extent, it has an inherent speed limitation that I don’t like. Almost anything over 10 wpm keeps the servo at the end of travel, making it impossible to detect the characters. I’m now looking at using a vibrator similar to those in cell phones, compliments of a good friend and fellow ham. Although not what I originally envisaged the vibrator does show better promise and a nice theoretical response to faster CW speeds. Coupled with a LED, it may turn out to be the best solution for me to listen to the radio. I know, but the combination might turn out to be better than the parts. Right now, I’ve only got the Arduino driving the vibrator. Still to be done is receiving and converting over-the-air CW signals provided via the audio jack of my radios.

Plans are under way for more Owyhee explorations, and while doing that I fully intend to try HF radio work from way out in the middle of nowhere. I’m building an end-fed, multi-band wire antenna that should be tuned to each band: 10m, 20m, 40m, and 60m. It’s only mobile in that you can easily carry it coiled up in the vehicle, to use it you have to park and deploy it. We’ll see how that works in practice, but I’ve got good expectations. I’ll be focusing, of course, on CW and PSK but when solo. If I have a friend along, I’ll be trying some phone work as well. More than likely, I’ll be band scanning and if I hear anything, I’ll pause on that and see if I can contact the other person.

Photography-wise, I’m currently teaching a beginning photo class, but with a twist. In all my previous classes I noticed that there was never a deaf or hard-of-hearing person attending. This time, I told the community education group that I would teach a beginning class in sign language. When I shared this idea with the few deaf community members I knew, the enthusiasm was outstanding. In the end, due to various reasons, there were only three in my class. We’re having a blast and there would have been at least two more were it not for an age limitation posted on the community education web page. That limitation didn’t apply to my class, but that exemption information was not passed on to the people that wanted to sign up. Word’s starting to get out there about this class, though, and I’ve mentioned I’ll offer it again, the same way. One of the reasons for doing this is that I just felt like turning the tables on the regular offerings…they’re oriented towards hearing people, the deaf have to get an interpreter. This time, though, it’s the hearing that have to get an interpreter if they try to attend.

I have also been investigating the use of the Shutterbug Remote with my Pentax K3 DSLR. Testing with an iOS device showed that the remote works well with the K3, but I’m getting crashes using the Android version of the app on my Samsung Galaxy Note 4. Testing with a Samsung Galaxy S5 shows it works reasonably well with that phone, so now I’m trying to determine whether or not it’s a setting, a FW, or a HW issue with my Note 4. An email to the developers has not provided any response, so I’m very unimpressed with the customer service aspect of their website. Enough that I’m not providing a link to it. It would be really nice to get this remote working with my phone as it’s a great little device which when used as an intervalometer provides better timing control capabilities than the built-in intervalometer mode of the K3. If I can’t get it working, I’ll definitely have to create an Arduino intervalometer or something.

I’ve built a new woodworking bench (above) in my garage along with a DIY woodworking bench vise (below). These will come in handy when I start building the Vardo.

On the Vardo front, I’ve started gathering materials to modify the trailer for the Vardo. It took me a while to figure out the best way to use my flatbed trailer for the Vardo, and still be able to easily use it as a flatbed trailer. One of the things I had to deal with was me being “greedy.” The flatbed trailer is 12’ by 6’ and I had been doing my designing based on that entire area.

Image of a 6 foot by 12 foot utility trailer with one pair of wheels. Sides are an open framework of angled metal. Tail gate is about 4 feet tall when up and contains a metal mesh. Parked next to a blue-green 1992 Chevy Blazer in front of the garage in the driveway.

This is the new utility trailer that will become the base for the Vardo. I’m especially happy to get the all metal bed.

I was going to have a big Vardo that had luxurious room inside. Kind of a contradiction to my original plans for a simple, cozy Vardo, actually. As a result, one of the things I had to figure out a way around was the six tie-downs on the trailer bed near the sides. I finally realized that they provided a perfect way to fastend the Vardo to the trailer, a la pickup campers: straps built onto the framework of the Vardo that connect to the trailer tie-downs via turnbuckles. To do that meant I had to narrow the width of the Vardo box to fit inside the tie-downs enough that I could hook them into place and tighten. It’s only a 6” loss in width, give or take, but it also freed up the solution to another issue: I wanted to put the same kind of mesh that I had on the tailgate along the sides of the trailer. That way, things put in the trailer wouldn’t roll out under the existing side rails. And I could use that now open area to store poles for awnings, and other such gear.

I’ve been doing quite a bit of fishing lately, for rainbow trout. Normally I would catch and release trout, but my wife and I have found that we like the fish. I’ve learned to fillet them so that we don’t really need to worry overmuch about bones while eating. Only about 15 minutes from my house is a great little pond where, so far, I’ve always managed to catch my limit every day. I didn’t use to fish that much, or to enjoy it, but I’m finding I do. I’ll probably go fishing rather regularly while retired, using that to supplement our diet with fresh fish on a regular basis. It’ll be interesting to see how the fishing goes as the weather warms up.
