Clearing my cobwebs

This weekend was about goofing off. Goofing off as much as possible. It all started like this:

… sunrise September 17, 2017

Officially I had to do some volunteer work for my radio club but that was over before 10am Saturday which left the rest of the day to do something I’ve had in my calendar for a while now: The Flying Circus.

We didn’t stay long but we made a day of getting there and back like we tend to do now and again. Typical trip down I-81 where you have to be crazy to be with crazy. But it was OK with both of us in the car together to stay distracted. Although I think my driving drives Gloria crazy. She has to listen to me postulate about statistics of queuing and crowding; the mathematical advantage of being in a small car in a big car world. 210 horse power helps but not as much as being small.

The venue for the RC event is atop a hill south of Covington, VA where people are flying all kinds of different aircraft from fixed wing to drones and even some cars and the like. But it’s mostly about flying something. It’s put on by Jeremiah at Stone Blue Airlines. Jeremiah owns the place there in Lynchburg two hours away from Covington. He’s helped me outfit some of my RC gear here that I fly. It’s cool that he’s made a living out of his passion. It’s really hard to tell when he is working and when he is playing. Which is I think the point to life.

After looking through my FPV goggles at other people flying we took back off for home in hopes of getting back at a decent  hour. We lumbered along the back way home up SR220 through some really pretty West Virginia and Virginia back roads. After a dinner at the Fireside Cafe it was slabbing it back home as fast as we could once the sun went down and both of us grew tired.

Gloria had a big morning on Sunday and presentation in the afternoon so we needed to get her back and rested. She had a good, productive presentation on how to make Kombucha. She makes really good Kombucha!

Not me. I took the day (Sunday) mostly off. Besides a 5 mile run at sundown I really didn’t do much but goof off with electronics, some photography, RC flying of various types, radio. Some people have said that my goofing off looks a lot like work. I resemble those remarks.

Oh, radio. I chatted with a “DXpedition” station from the Czech Republic operating in Mauritania using call sign 5T5OK. I was parked on a 14 mhz frequency when I noticed the activity on the spectrum scope. Turns out these guys were testing their station and I was able to snag them in a “pile up” on the first call once I figured out how they were set up on the split frequency. We really didn’t chat long and they went on to making more contacts. It’s about 4,200 miles from here to there. I’m always amazed that I can just “key up” and talk to a totally different country on the planet. Makes the world seem really small. I was on and off the radios all day today which was particularly fun.

I’m working on an adjustable square wave generator circuit with a 555 timer chip. I’m not terribly good with electronics so this is half learning and half doing. I want to create a string of LEDs that use a transistor to switch between on and off at a rate that I can control with the timer chip. The circuit is gonna look something like this:

555 timer circuit

I got my bench power supply back from the shop so I can start building stuff again. Or breaking stuff, depending on how badly I mis-calculate things like voltage, current and the like. My method is less “Ohms Law” and more “Poke-n-Prod” until the blue smoke comes out. When I see blue smoke it’s generally back to the drawing board. It’s a good way to learn but leads to a lot of dead parts.

I’m sure I could buy the circuit from China for a buck but what’s the fun in that? I have this idea on making an LED string look like it’s pumping electricity like water  through a tube. I want to vary the alternating lights at a rate and amplitude I can control. Yea, boring.

Mongrel and I got to walk together some today. When we weren’t moving he was chasing his tail. I can’t tell if he is goofing off like cats can do or if he’s frustrated that he can’t control it. One thing’s for sure is that he is very transparent because of that tail which exposes his current mood. The little biting flies were bugging the crap out of us both too.

We were also still a lot today. It’s interesting to watch Mongrel. He generally sits facing opposite of me. If I were to lay down he sits on top of me. Must be some weird instinct thing going on there. Seems to watch out after me when we are together. Anything out of the ordinary while he is on watch will render a “growl”. Could be a dog ½ mile away or a person riding a horse. He just lets me know it’s out there.

Watching everything that is moving.

When all that is done and we are back in the quiet, cool of the house where his guard comes down he starts to slow down after some dinner. Quietly protesting that he doesn’t want to be inside he climbs in his box next to my desk. He starts off looking at me. Then falls asleep.

“In the safety of my box”

Soon he is on his back with his feet in the air. This cat can sleep like none other I’ve ever met. And will sleep like that all night long.

I hope you’ve had a day that was fun like ours. And that you are back in your safe place where ever that may be.

I’m done goofing off. Work tomorrow. Headed to my box.
