Morning Update

Not a pleasant morning at all here in central Maryland, so I opted to run in the pool. More storms later today in this already extremely stormy and wet summer. How long until autumn again? 😀 I’ve written before about how the benefits of owning a pool don’t quite make up for the expense and hassle required to maintain it, but I will say that it’s great to have the pool as an exercise option on days when I don’t feel like doing anything else outdoors. If the storms hold off long enough, I also hope to get out to swim later this afternoon.

I’ve settled on this recipe for what remains of my bag of dark roast beans I bought last May:

  • Beans: Lost Dog “Mocha Sidamo” Ethiopian dark roast
  • JX: 2.5 turns (75 total clicks, or 25 on the grind chart)
  • 80°C water
  • 14 grams coffee / 180 grams water (around 1:13)
  • One new paper filter (pre-moistened)
  • Recipe: “Basikairoo” (inverted: add 50g water, swirl aggressively for a few seconds, top up to 180g starting at 1:00, invert at 2:15, press for 30s starting at ~3:00)

This is only slightly tweaked from when I first brewed this recipe. It produces a good cup fairly consistently, with only slight variations in strength. I wonder if the length of time spent “swirling” makes any difference in the finished product. The recipe specifies 3 seconds, but I haven’t been timing it.

Afternoon Report

The “AC Loss” issue with our new alarm panel seems to be resolved, at least for now. After reprogramming the last few zones in the system, I unplugged the system and let it run on battery for several minutes. Then, I swapped out the old Ademco 4300 X-10 transformer, replacing it with the transformer that came with the new panel. When I plugged it back in, the AC Loss condition cleared up. I have a hard time believing that the transformer was the issue. I read the panel voltage across terminals 1 and 2 with both transformers, and it was exactly the same — about 16.7 volts AC. Maybe the panel was just in a confused state, and needed an actual AC power loss and recovery to “reset” itself. However, the problem did persist through several power cycles (although I’m not sure I ran the panel on battery at any point). The only way to find out for sure would be to swap the old transformer back in, and see if the problem returns. However, since it’s working now, I’m inclined to leave it alone.

I decided to try doubling my cold brew recipe this afternoon. I put 2 slightly heaping scoops of Wellsley Farms breakfast blend into the (inverted) AeroPress, added room temperature filtered water up to near the top, stirred for 1 minute, and pressed. Then, I split the concentrated coffee equally into two tumblers, topped them up to roughly 8 ounces, and added ice and a couple drops of stevia to each glass. The extra coffee made it a little bit harder to press, but it turned out just fine. I couldn’t tell any difference from my single cup recipe. The next time I do this, I may measure the total amount of water per glass more carefully, then press into a carafe or pitcher instead of directly into a tumbler.

This and that

I had hoped to take a bike ride this morning, but ended up sleeping until almost 9:00. It was probably just as well, as it’s very hot and humid today, and would have been a rather sweaty ride. The reason for my oversleeping was that we got a call around midnight from our alarm monitoring company because of a “trouble” condition. Turns out that the newer Vista panels have “trouble” reporting enabled by default, while the older ones didn’t, and I didn’t think to turn it off when I programmed the new panel. Earlier in the evening, I had popped the cover off one of the wireless contacts to check the battery, which caused the zone to go into “trouble”. I’m not sure why the alarm company called at the time they did, but it does confirm that reporting is working! The panel is still showing “AC Loss” this morning, in spite of the power being just fine. When I get to messing with it again, I’ll try unplugging it, running it on battery for a few minutes, and plugging it back in, to see if it resets. If not, I may try swapping out the transformer, and if none of that works, I’ll contact the alarm company.

The pool SWG is still reading an abnormally high temperature today. At least it’s consistent. When I get to messing with that, I’ll try re-seating the tri-sensor cable and see if it corrects itself. I may also pull the tri-sensor itself out of the manifold and take a look at it. If none of that works, I’ll test it with the tri-sensor simulator to narrow down the source of the problem, and contact my Autopilot dealer to see what he recommends. This is a rather easy issue to work around, either by calibrating the temperature reading down, lowering the Chlorine output, or turning off the setting that automatically adjusts the output based on the water temperature. Assuming I can’t fix this easily, I’m inclined to ride it out for the rest of this season, and buy any needed replacement parts over the winter.

I brewed yesterday’s dark roast coffee recipe again today, exactly the same way, except I used 180g of water instead of 200g. Truth be told, I didn’t notice much of a difference from yesterday. It was a pleasant cup of dark roast. I have enough beans to make 7 or 8 more cups, and I’m probably just going to be boring and stick with this recipe until they’re gone.

Broken stuff

The abnormally-high temperature reading on my pool’s SWG that I noticed 10 days ago is back. This morning, it was reading 94°F when the actual water temperature was 80°F. The reading was consistently about 14-15° too high every time I checked today, all the way up until 7:00 or so, when I went out to swim. I’m going to try disconnecting and re-seating the cable that connects the tri-sensor to the controller, and I’ll take a look at the contacts to see if they’re dirty or oxidized. Maybe it’s just a bad connection. I went ahead and ordered a tri-sensor simulator, which is a little widget that plugs into the controller and generates a fixed temperature, salt, and flow reading. If cleaning and re-seating the cable doesn’t do the trick, then I can use the simulator to determine whether the problem is with the tri-sensor or the controller.

In other news, we are preparing to get rid of our landline phone service, but before we can do that, I have to convert our security system to use cellular and/or internet monitoring. The problem is, the panel’s firmware was too old to work with the new communicator, and to make a long story short, I had to swap out the entire panel. It’s kind of amazing that the panel is still in production, and is practically identical to the version that was produced 21 years ago when I originally installed it. All I had to do was move all the wires over and then reprogram the new panel (a tedious, but not difficult, job). That was today’s project. Now, the weird thing: the new panel works perfectly, except for one thing: for some reason, it thinks it doesn’t have AC power. The alpha keypad flashes “AC LOSS”, and the fixed keypad says “NO AC”. This is normally what it does during a power outage, when it’s running off the battery. Get this, though: it does this even with the battery disconnected. So, if it doesn’t have AC, I don’t know how it can possibly be working. Induction? Hamsters? Who knows. The voltage from the transformer is fine: I read 16 volts AC at the transformer itself and the connection terminals on the panel. I’m wondering if maybe I can just ignore this, as everything seems to be working, but I’m concerned that it may not be charging the battery. If it’s not, I’ll find out in the next few days once the battery runs down. As a last resort, I may try unplugging the panel to simulate an actual “NO AC” condition, and seeing if maybe it resets itself when I plug it back in. But I’m not holding my breath, as the problem has persisted through several power cycles. I’m also going to reread the manual and see if there’s anything I missed with the initial setup. If all else fails, I’ll contact my alarm company, and see if they have any ideas.

Running etc

Pool update: after yesterday morning’s weird SWG behavior, I returned from work in the late afternoon to find everything ostensibly working normally. The temperature readout had corrected itself, and cell volts/amps looked good as well. The Free Chlorine this morning was identical to yesterday’s reading at ~4.5ppm. Not sure what the issue was. This morning, I pulled the cell out and inspected it, which is something I try to do every year around the end of July. There was very little scale, which indicates that the controller’s self-cleaning function is working correctly. The manifold inlet screen was clean, and the check valve looked good. Some of the cell plates (particularly the ones in the center) have worn down a little bit more, which tells me that the cell might finally be nearing the end of its life, but it seems to be good for now. Since I had it out, I went ahead and acid-washed it for good measure. Next spring, I’ll have to decide if I want to retire the cell and put my new one in service. I bought it in 2019, thinking I’d need it a lot sooner.

It was another pleasant morning, and I got up with my 5:30 alarm, so I left at 6:40 and ran for 6.8 miles. It was a great run, and I would have gone farther, but I had to be home at 8:00 to take delivery of a new winter pool cover. Weather permitting, I am going to try to take an 8 or 9-miler on Saturday morning.

Miscellany

We took the “kids” (age 20 and 17) for an overnight trip out to far western Maryland Monday into Tuesday. We visited Swallow Falls State Park, the Maryland Rock Maze, Sideling Hill Creek State Park, Cumberland Narrows, and Washington Monument State Park. We got some hiking in and found several geocaches. Even though we were away less than 36 hours, it was nice to get out of the house for a while, and brought back memories of trips like this we used to take back when the kids were smaller. Who knows if we’ll ever be able to drag both of them out for something like this again!

I rode my mountain bike to work today, for the first time since June 7. Although I’m no fan of mountain biking in the heat and humidity, the main thing stopping me this summer has been the wet and stormy weather we’ve had since the second half of June. My schedule is most conducive to mountain biking on Wednesdays, and most weeks, the trails have been too muddy. Currently, we are in the midst of a several-day dry spell, so conditions were pretty good. I stuck to familiar trails, and they were in mostly good shape, but there were lots of muddy patches in areas that aren’t usually muddy. I passed around 8 hikers on the Howard County side between Belmont and Rockburn Branch, which is 8 more than I usually see in that area weekday mornings. I guess the beautiful early August weather brought everyone out of the woodwork. Temperatures were in the upper 60s, with low humidity.

On the swimming pool front, something seems to be wonky with our SWG today. This morning, I went out and noticed that the temperature sensor was reading 5-8 degrees higher than the actual water temperature. I calibrated it to match, but I’ve never had to do that before. I ran a test, which showed normal cell amps, but then after I exited the menu, the display started flashing a low amps warning. Not sure if the two issues are related. The temperature thing is usually related to the tri-sensor, but the low amps thing usually points to the cell, so I’m not sure what to make of this. I power-cycled the controller and also backwashed the filter, but neither helped with the temperature anomaly. The low amps display went away after a minute or so, but the Chlorine has been running a little lower than expected this week, so I wonder if this has been happening for a few days. This evening, I’ll pull the cell out and inspect it, and I’ll also look at the check valve and see if there’s anything impeding flow through the tri-sensor. The cell is 14 years old, and has outlasted the original controller and tri-sensor, so it could be that it’s finally time for a new cell. However, it doesn’t seem like a bad cell would cause the issue with the temperature reading. I’m sure I’ll get to the bottom of it, and I’m sure it’ll end up costing me more money. That’s just life with a pool.

Hot Day Hybrid

Day 3 of the heat wave: after skipping Thursday’s run in favor of the pool, I wanted to run today, even if it was only a short one. I hit the road at 8:15am, when it was still below 80°, and although it was plenty humid, it did feel slightly less oppressive out than it did yesterday or Thursday. It might just be that I’m getting acclimated to it. Whatever the case, I ran 4 miles at 10:00/mile, and felt pretty good. When I was finished, I put on my swim gear and ran for 30 more minutes in the pool. It was the first time I have done regular running and pool running in the same session, and I think it worked out well. Four miles is long enough that I felt like I got a decent run in, but short enough that I didn’t overheat and lose a ton of fluids, and the pool was a great way to cool off afterwards. Ideally, I’d like to get out about an hour earlier, but I didn’t wake up until close to 7 today. I must have needed the sleep.

My experiences with running in the heat and humidity this summer have convinced me that I’d like to pick up a running-specific hydration vest, but there is a mind-numbing variety of them to choose from, so I’m going to have to do a little bit of research. I’ll probably hold off on buying anything until REI has their next sale and 20% off coupon (maybe around Labor Day).

Here’s something that has never happened to me in 22 years of pool ownership: I walked outside earlier and saw that the Polaris tail sweep hose had come disconnected from the main unit. I retrieved both of them, and nothing looked broken. I was able to easily push the tail back onto the ferrule, but it was kind of obvious that whatever secured it there was missing. I found a parts diagram and saw that there’s a plastic clamp that’s supposed to go there, but it was nowhere to be found. I’m guessing it just broke. A new one costs about $3.50, but I jury-rigged it with a zip tie for now, which seems to be working. I don’t expect it to last too long, but who knows.. maybe it will surprise me.

Update (9/13/23): The zip tie fix lasted until today, or just over 6 weeks. I just put a new one on, and will add the $3.50 clamp to my list of items to buy for next season (it might be cheaper over time to just keep sacrificing zip ties, but it would be much more annoying 😀).

Pool Notes

I had to add acid to the pool this morning for the first time this season. I think this is the latest it has ever gone before needing acid. The season started off cool, and we have yet to have a big heat wave with multiple days in the 90s (though it has been plenty humid) and as a result, the water has stayed cool as well. It finally edged over 82 yesterday, and the pH has been stable at 7.8 up until today.

I forgot to turn the SWG back on after draining a bunch of water out of the pool yesterday morning (crazy amount of rain over the past several days) and as a result, the pool dropped from 5-6ppm Chlorine to 3ppm yesterday, which is a little bit lower than I like to keep it. I have a bucket of 73% Calcium Hypochlorite that I keep around for “emergency” chlorination, because it has a much longer shelf life than liquid Chlorine. I had not used the Cal-Hypo in over a year, and it has been sitting out in my shed the entire time. I added around 2 pounds yesterday evening, and this morning, the pool was at 8ppm free Chlorine. So, I’d say the stuff is still good. I left it indoors overnight, and by morning, the room smelled like a pool store, so I think the shed is still the right place for it. It definitely needs ventilation, as the container seems to out-gas a lot, and I know from experience that the fumes are corrosive. I’m happy to have the Cal-Hypo on hand when I need it, but for the future, I probably don’t need 50 pounds of it. A 25-pound bucket should be plenty, and is easier to handle.

Early Fall Ramblings

It’s that time of year where I always feel like summer has slipped away before I had the chance to do everything I wanted. This year, in particular, I didn’t get out in the kayak very much; lately, though, I’ve been making up for that. Last weekend, Michael and I joined a few of my geocaching friends for a really nice 9-mile paddle on the Patuxent River in southern Maryland, and today, Cathy and I drove over the bridge for a morning paddle on the headwaters of the Chester River. I love paddling this time of year, as the temperatures and humidity start to drop and the leaves start to turn. I hope to get out one or two times in October. I’ve occasionally considered starting to acquire some colder-water paddling gear, so that I can keep paddling later into fall and early winter, but have yet to take the plunge. It seems like a paddling jacket, wetsuit and neoprene socks might be an economical way to extend the season for a few weeks. Then, I could see if I get enough use out of that gear to warrant a larger investment in a dry suit, which would allow for year-round paddling.

Many years, I find myself wishing that I had gotten in our pool more often, but not this year. According to Apple Health, today was my 83rd time in the pool in 2021. Working from home 3 days a week provides more opportunities to swim during the day, as I can keep an eye on the weather and pick the best time to jump in the pool. The weather this month has helped to extend the season, as well — we have had a lot of sunny days, and no extended runs of cool, damp weather, which is what led to the early demise of last year’s pool season. I can’t even remember the last time I was in our pool as late as September 30. We will see how long we can keep the season alive. In October, the leaves make it tougher and tougher to keep the pool clean, and eventually you reach a point of diminishing returns, where the hassle of cleaning the pool exceeds the desire to swim.

I am hoping to do a little bit of outdoor top-rope climbing this fall. I have still been climbing regularly at the gym, and still really enjoy it. Earlier this year, I picked up some equipment to rig up a top-rope self belay. When I can get my act together, I want to head to Ilchester or Alberton Rocks and do a couple hours of solo top-rope and rappelling. I had been waiting for cooler, less humid weather, and it seems like it’s here now.

Anyhow, that’s enough for now…

Summertime

Summer is definitely here. Yesterday, we got in the pool for the first time this season. It was a bit later than we usually do, but it took a long time for the water to warm up this year. Last year, during the height of the pandemic, our pool got a LOT of use. I think I got in the pool more times last year than the previous 10 years combined. I used it quite a bit for exercise. Our pool is 40′ long, and it’s possible to swim laps in it, but you have to stop frequently to turn around. It wasn’t until last year, when we acquired a swim tether, that I really started swimming a lot. Swimming with a tether is akin to walking on a treadmill. You don’t go anywhere, but you can swim forever, and I now feel like I’m getting real exercise rather than constantly having to stop to turn around. I’m hoping to keep up the regular swimming this season.

I get the feeling that we are near the peak of this year’s Brood X cicada emergence. They are everywhere, and I’ve been spending a lot of time fishing them out of our pool. Unlike some other insects, periodical cicadas seem to be completely helpless once they hit the water. They can survive awhile in the water, but they can’t get out on their own. I’ve lost count of how many I’ve rescued. Once you get them out, though, they seem no worse for the wear. They really are fascinating creatures. If all goes according to the grand plan, we’ll be out of this house before the next emergence in 2038, so this will be the last year I have to fish them out of the pool.

I went out on the mountain bike this morning. Last year was my first exposure to summer mountain biking in a very long time, and I forgot how much more I sweat on a MTB than when biking on the road. I think it has a lot to do with the nature of the activity — it requires a lot of short bursts of exertion, the speeds are slower (meaning there’s less cooling from air movement) and sometimes I have to get off the bike and push for short distances. All of that adds up to a LOT of sweating on hot, humid days, and last year, I quickly learned that a single water bottle was not sufficient to keep me hydrated through a 2-hour mountain bike ride. Also, when riding technical single track, it’s a lot harder to find opportunities to grab the water bottle and drink. Put those together, and I found myself getting dehydrated and running out of energy frequently. This year, I decided to start using my Osprey hydration pack in lieu of a water bottle, and it has been a clear winner. I can drink whenever I want, even through technical sections of trail, and I find myself drinking much more often and staying hydrated, and I can complete a 2-hour ride without pooping out and with plenty of energy to spare afterwards. Today, with temperatures in the mid-70s and the dewpoint hovering just under 70, I rode for 2 hours and went through 2.5 liters of water.
