Drone around and find out

On Saturday, it was a pretty nice day so I took my Mini 3 Pro drone with me cross country skiing. They were snow making so after doing one loop to check everything out I decided to take the drone around a “half loop” where I’d ski just the bit with no snow making and back, because skiing through the area where the snow makers are active is like skiing through a howling blizzard.

I set up and started “Active Track” mode and started off down the Hale Bopp trail and then past the lodge and around half of the Ares loop and back. The drone did its usual excellent job of following me, even correctly reversing course where I did. However when I got back to the lodge area, I discovered it wasn’t following me. Looking at the controller screen, it was about 200 meters up the trail, just around the end of the s-turning downhill run.

I took manual control and flew it back to me. I decided I’d take it for one last run up the Hale Bopp trail and back, so I pointed its camera at me and set up and started “Active Track” again. I stashed the controller under my jacket as per usual and was getting my gloves back on and my hands in the ski pole straps when I noticed it slowly circling me to the left. I don’t know if it thought I’d started moving and was circling to get behind me or if I’d accidentally put it in POI instead of “Active Track”, but it looked like it had a mission and it wasn’t the one I wanted it to be on.

Before I could dig the controller out of my jacket, it softly touched down on the blanket of snow on the roof of the lodge building. The snow was deep enough that it sunk in and the motors wouldn’t restarted because they were blocked with snow. I was still getting a video signal, however, although I didn’t realize that could be useful to me until it was too late. (Foreshadowing!)

I asked the guy who was working inside the lodge if they had any means of getting snow off the roof or anything, and he said they didn’t, but he handed me a plastic tube that was approximately 10 feet long and just not quite long enough to hit the drone. I realized I wasn’t going to be able to get it down. I also realized I would need to leave very shortly to get to the Banff Mountain Film Festival. Unfortunately I also realized at that moment that if I’d thought about it before I started futzing around with sticks, I could have downloaded the videos off the drone onto the controller, but now it was too late.

My poor little Mini 3 Pro

I left Bristol, and once I got home I made a plea to members of the Rochester Cross Country Ski Foundation that if they’re going to Bristol to have a look for my drone and let me know its status.

Unfortunately I couldn’t go back to Bristol on Sunday because the Banff Mountain Film Festival was a matinee, but I received a couple of reports that was still on the roof.

Monday morning I set off loaded for bear. I had 3 things with me, as well as my ski stuff:

  • My big drone, the DJI Air 3
  • A tie down rope for my kayaks that has a metal hook on both ends and
  • A 50 foot dog leash

I tied the tie down rope around my drone so that one of the hooks was dangling below it. I clipped the dog leash to it to act as a safety so if the big drone crashed, I’d be able to bring it back.

There was no snow on the roof at all, but the drone was sitting exactly where I left it. The snow obviously hadn’t slid off, and I think it sublimated off rather than melting because there was no signs of melting and refreezing, even in the snow off the trails. That bodes well for the drone actually not being water damaged, but time will tell.

My plan worked perfectly. I was able to slide the hook onto one of the arms of the stuck drone, gave it a little tug and it started sliding off the roof. It hit a window sill on the way down and bounced a bit, but I managed to catch it in mid air.

Safe and sound!

I haven’t fired up the Mini 3 Pro to see if it still works – I’ve decided to wait a bit to let it warm up and dry out. But at least I’ve got a fair chance of getting the videos off the SD card.

Cross country skiing

So three winters ago, I decided to see if I could possibly get back into cross country skiing without buggering my knees up too much. For most of that first winter, I skied at Cumming Nature Center, which is about the nearest place that had rental equipment. I had just come off a really great year of kayak racing, except for the hip pain that was making it increasingly untenable to keep paddling, and I pretty much did no paddling after August except for the Long Lake and Seneca Monster races.

So I was still pretty fit when I took up skiing, and I really enjoyed skiing around Cumming which had a great network of trails and a variety of conditions. Also their rental equipment was pretty great. The only drawback was the driving distance. I usually arrived at Cumming just as the sitting pain was becoming unbearable. On the way home I’d have to stop at least once and walk around and stretch a bit to alleviate the hip pain.

After four or five times renting, I decided to buy some equipment, a mixture of stuff bought on-line and my friend Dan’s old skis. Dan introduced me to something called “Start Tape”, that was like a 1-wax system that you applied like a tape to the wax zone of your skis. I don’t know if it’s because the wax pockets are so much better engineered that when i was skiing in the 70s and 80s or just that my expectations were lower, but I’ve continued to use the Start Tape.

Buying also meant I could ski closer to home at Durand-Eastman park, which had a mixture of groomed trails and skied in trails, and wasn’t a bad place to ski as long as the weather held. I still went back to Cumming and a few times to Bristol when snow was scarce on the ground because Bristol makes snow. It’s only a 1km or so loop, but it’s consistent snow when everybody else is ice and puddles. And when the snow is good, they have an additional loop that’s about 1.8km.

Only drawback of Bristol is that most of their customer base appears to be skate skiers, so they’re not very consistent about putting in grooves. Due to the knee problems that caused me to quit skiing the first time in the 1980s, I don’t do skate skiing any more, and I really want those grooves.

By the end of that first winter, I was tolerating the length of the drive better, and I was skiing as much as 9 or 10 kilometers at a time. A far cry from when I was training for the Canadian Ski Marathon and loppers, but I sure remembered why back when I was doing everything (skiing, orienteering, backpacking, canoeing, etc), cross country skiing was my favourite. If you don’t believe me, look at my domain name, xcski.com.

Second winter came along, and this time I did almost no paddling during the summer because of the hip pain problems. And it turned out to be a complete wipe-out for snow – the only place I skied was at Bristol, around and around that 1km loop. I think I made it up to 7 or 8 kilometers at a time. The driving wasn’t bothering me as much, and I’d often go 3 times a week. Still felt great to ski. I often felt like I was slower than the slowest skate skier, but faster than the fastest other classic skier. I took my drone a few times to get footage of myself skiing using “Follow Me” mode which was pretty cool.

It’s now the third winter. I did get out a very few times in the kayak this summer, but only for an hour or so each time. But the fitness is way, way worse this year. Most of the skiing has been at Bristol, because we haven’t had much good snow. Cumming hasn’t opened for more than a day here or there, but not fully groomed, and I managed Durand once before it all melted away. And I’m slow, just horribly horribly slow. I get one decent loop which takes about 1.5 times as long as it took me two years ago, and then the rest of it is ski for a bit, catch my breath for a bit. I’m up to 3 loops and a bit of this out and back trail called Halle-Bopp. Maybe 4 kilometers total. It’s sad. But if the winter lasts a bit longer, maybe I can add another loop or two by the end.

Except I’ve got a problem. I feel like I shouldn’t even write about this in public, because people are going to tell me to stop skiing. The problem is that my knees are acting up. My right knee especially. For a day or so after I ski, I get a terrible stabbing pain when walking up and down stairs, and sometimes even when walking on the flat. I’ve been grinning and bearing it mostly because I don’t want to give up skiing, but I’m extremely concerned.

Update on Droning

So evidently I forgot to update after So this is happening. Since that time, my DBA got rejected because the county clerk thought that “RochDrone” was too close to an existing DBA for “Rochester Drone”. I couldn’t find anything about this “Rochester Drone” company, except an unclaimed listing on yelp.com that pointed to a domain that doesn’t exist.

Interestingly the county clerk didn’t follow the instructions from the letter from LegalZoom that said to return it to them in the self addressed stamped envelope, and instead sent it to me. I sent it on to LegalZoom, but it’s just as well that they did send it to me, because otherwise I would have had no clue what was going on. I waited a few weeks for LegalZoom to get back to me with my next steps, but eventually I got tired of waiting and so I went down to the clerks office and registered a different name, FlyerCity Drone. I of course also registered the new domain and with help from Bob Raymonda, I got the new site up and running.

Registering a DBA in person is dead easy, and only costs $33 and only takes a few minutes. If I’d known how easy it was, I never would have bothered with LegalZoom. I’m certainly not going to use them again.

About 2 or 3 weeks after I’d done with that, I finally got an email from LegalZoom, which they described as their final attempt to contact me. Except it was also the first time they’d tried to contact me since the last time they sent me a couple of forms to get notarized. I wrote them back and said in view of the fact that they never contacted me for over a month, I had done the registration without them, and I would like a refund of the registration fee, since I knew the county clerk had returned it to them. They refused. Bastards.

Meanwhile, I bought a second drone – this time an Air 3. The Air 3 is a much larger and more capable than my Mini 3 Pro. The major features are a second semi-zoom camera, and omni-directional obstacle detection (as opposed to front, back and downwards only). I’m looking forward to finding out all the things I can do with it.

Finally got it!

So I already wrote about my first attempt to do “Active Track” with my drone at Bristol Mountain Nearly lost my drone today. My second attempt got abandoned because after I launched the drone and was trying to set up the video when a gust of wind took it and drove it into the bushes. The third time I think I forgot to start the video recording. The fourth time, I bought a screen shade / screen protector so I could see the screen better, but I forgot about the big video start/stop button on the top of the controller, so it stopped recording as soon as I tucked it into my jacket, and started recording again when I took it out at the end.

But this time, it all came together. I decided not to tuck the controller into my jacket, and just let it pendulum around in front of me. That was mostly a factor on the big climb at the turn-around on the Hale-Bopp train. But I checked that it was still recording a couple of times, and it seemed to be recording fine.

Bristol Drone Video

Ok, there’s one weird thing – at one point it gets very close to a small branch, I can’t tell if it touched it or not, but the video got strange and wobbly. About 3 minutes later, it gets close to another branch. This time, it really doesn’t look like it touches, but the wobbliness clears up. I wonder if the gimbal is a bit frozen and it’s just bouncing around. I’ll have to look to see if there’s anything on the logs.

Oh, and a second weird thing – on the second loop around, the drone hits that very same branch and crashes. Maybe it was harder to see because the snow got knocked off the first time, but I don’t know. When I tried to relaunch it, it first wouldn’t climb, and then when I tried to land it, it suddenly took off upwards and hit a branch way above me and crashed again. I figured there must be some snow in one of the motors or something so I put it away..

Another drone day

It’s way too warm to ski, I’m way too sore to bike, so I went out and droned. One of the things I was curious about was range – I see people complaining that although DJI says you can fly the drone up to 10 kilometers away from the controller (but only 2 kilometers from the controller in the EU) but they only get a kilometer. I wanted to see how far away I could fly the drone and still see it, or how far away before I got a loss of signal and an automatic return to home.

So I searched for a place with a very good long line of sight. I settled on the Great Embankment Park (GEP) on the canal. I was thinking of Durand-Eastman Park, but the wind was blowing out towards the water, and I didn’t want to get into a situation where my drone was heading out towards Canada without a signal.

GEP is a good place to play with a drone because it’s got several sports fields, and then that long stretch of canal. And being Monday, not too many cyclists and walkers on the path, and being February and the canal is still mostly empty and frozen, nobody to worry about there either. Not the most interesting video, but good for practice.

I discovered many things during today’s flight.

First was that it didn’t matter if it was below the horizon (in the canal cut), above the horizon but below the tree line, or above the tree line either up-sun or down-sun, I would lose sight of the thing well before 400 meters. (I did some blind flying where I couldn’t technically see the drone, although I knew exactly where it was and could see through its camera on my controller – that’s technically illegal, but no harm no foul.)

Second was that I completely misunderstood how to activate “Spotlight” mode. There are three special modes that appear at the bottom of the screen after you draw a square on the screen of the controller with your finger. Those are “Active Track”, “Spotlight” and “POI”. I wrote about Active Track in my last blog post, and POI isn’t all that interesting to me because it just circles around the thing you’ve drawn around. Spotlight keeps the camera pointing at the selected point no matter how you fly around it, even if the selected object is moving. But the thing is that when you select the box, and the menu pops up, if you want Active Track or POI you have to select them, and I thought that’s what you’re supposed to do with Spotlight, but when I did that the menu would just go away. It turns out that Spotlight is selected by default and I wasn’t supposed to select it. Oh well, hopefully I’ll remember that for next time.

Third was that a very useful drone move is diagonal flight, where you point the drone and thus its camera off at say a 45 degree angle to the left, and then try to balance the forward and right movement of the right joystick to create straight line motion. I practiced it a lot today but I’m going to need more work on it.
