A Return Update

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.
