Ecobee Air Conditioning Update

Ecobee 3 thermostatIn honor of the bouncing seasons, I turned on my air conditioner a couple of weeks ago. In Minnesota that means you remove the wintertime weather covers from outdoor compressors and then turn on the dusty circuit breakers.

Fortunately I had performed a best-effort wiring of the AC into my new thermostats. All I needed to do was tell the Ecobees to look for AC, and to turn it on. It worked.

AC and heat in our home are completely different systems: while all air conditioners use blowers, not all heating systems do. Our heat uses hot water radiators. I set up a separate “comfort setting” in the Ecobee so that heat sensors wouldn’t confuse the AC system.

Does God scare kids from Scouting?

God commandsRecently, I spoke to a young adult who avoided attending a funeral. To quote, “The religious stuff creeped me out.”

This is a common reaction from people who haven’t confronted choices of faith, or haven’t resolved them.

Most religious institutions aren’t trying to creep people out. Shouldn’t we minimize or prevent such feelings?

Boy Scouts practically excludes youth brought up outside of religious groups. I don’t think the founders of Scouting wanted to exclude any boys from Boy Scouts. I think we can fix it.

My favorite meme from 2015

A neighbor has a variant of the Gadsden Flag flying under his American Flag. Instead of yellow, it’s black, but it has the snake and the “Don’t Tread On Me.”

I haven’t found anyone on the Internet who offers a Gadsden Flag with the “Send Snacks” motto. I’d buy one in a second.

This is also a “test posting” – WordPress has a “featured image” setting and “image post” format. I’m wondering what they do.

 

Trolley Misses Matildaville

Dickey's Tavern, Matildaville, VA

A previous post about the Great Falls and Old Dominion trolley line found discrepancies on early 20th century maps of it. The earliest maps routed the trolley through the old Prospect Hill village on Old Georgetown Pike, just west of today’s Madeira School. But today’s Old Dominion Drive follows the old trolley road bed, which intersects the Pike much farther west. This was either a map error, or the developers rerouted the trolley line in the early teens.

This early route would have run near the now-abandoned town of Matildaville, VA, the former site of Dickey’s Tavern (photo above, courtesy of DC Public Library). The expert on Matildaville seems to be Debbie Robison, so I looked her up and asked her opinion. She thinks it’s a map error. She noted a misspelling error that appeared on an early map and propagated to subsequent maps. She herself had seen no evidence of abandoned tracks or roadbed in the Matildaville area, though she didn’t search off-trail.

So the likely conclusion remains “map error.”

The Final Ecobee

Ecobee 3 thermostatLast night I installed my third and final Ecobee 3 thermostat in our home. My children will no longer need to freeze/boil in their bedrooms just because the thermostat doesn’t know any better. Like the first two thermostats, this one required an isolation relay. This post explains the wiring. I also added a “C” wire to power the thermostats.

The people at Ecobee recommend that you hire an HVAC contractor to do this wiring. Follow these instructions at your own risk. Continue reading The Final Ecobee

A Trolley Line Mystery

Trolley station at Great Falls Park, circa 1910While studying maps of western McLean, Va, where I grew up, I uncovered a mystery.

In 1902, magnate John McLean and politician Stephen Elkins started building a trolley line from Washington, DC, to Great Falls Park (photo at left; see Wikipedia). The tracks show up on maps from 1904 until their removal in the 1930s. The roadbed became Old Dominion Drive, one of the “main streets” of McLean, Va.

Here’s the mystery: The earliest maps showing the tracks between McLean and Great Falls route them differently from today’s Old Dominion Drive. The older maps show the tracks crossing Georgetown Pike near Madeira School, at a village called “Prospect Hill.” The tracks then cross Difficult Run next to the Pike’s bridge. Starting in about 1915, maps show the tracks following today’s Old Dominion Drive.

Why did it change? Was the first map wrong? That seems most likely to me, but still pretty surprising. I’m asking around for evidence that the tracks might have moved. I doubt there is any, but it’s worth investigating. [See update in a newer post]

100 years of my childhood neighborhood

neighborhood

My neighborhood went through dramatic changes while I grew up. I was 10 miles from Washington, DC. Changes are even more dramatic since I left, about 40 years ago.

I went to the US Geological Survey and collected every map I could find of my neighborhood from 1890 through 1994. I lined them all up and made it into a video. It could be better, but it’s interesting.
