epriestley added a comment to T13689: A Considered Review: 3D Printing.

They sell "broken" Ender 3 printers on eBay for like $75 shipped. I ordered two. One had a bad board (a $40 part); one had a bad Y limit switch (a $3 part) -- so the actual cost per printer seems to be around ~$100 if you're familiar with how they work and can identify which parts aren't working.

epriestley closed T13694: Create a "BRK/First Alert" smoke detector connector adapter as Resolved.

I traced the alarms back to Breaker #8 in Panel #2 (the detector tool actually worked okay this time). I disconnected the breaker and verified that killed the circuit. I swapped the alarms and updated the map of known breakers with this new information:

No great surprise, but the blue boards seem about the same as the red boards and have the same problems:

The genuine article is not a JST-VH 4-pin connector -- the connecting clip is a little different, and there's no hole in the housing for (unused) pin #2. However, the pin size and spacing is right, so you can cut the connecting clip off a JST-VH and melt one of the pins out and the connector will fit well enough.

I bought an oscilloscope and tested the speed signal of one of the new red boards once it arrived. The scope showed the perfectly sensible signal I expected, and the signal came off the board fine once I hooked it up. So maybe the first couple boards were legitimately bad?

epriestley added a comment to T13694: Create a "BRK/First Alert" smoke detector connector adapter.

This connector has a 4mm pin pitch, but I had a great deal of difficulty finding a likely-seeming bare connector with a 4mm pitch. After resigning myself to a Digikey quest for a connector that will fit a board on T13692, which also has a "4mm" pitch I realize the pitch is probably not 4mm but 3.96mm -- a wonderful pitch for which many connectors are readily available.

Couple of years ago the furnace wasn't working so well. Light comes on, three reds. Pressure switch stuck open. I take off a panel, pull the pressure switches. The contacts close properly. No clue what's wrong. Call an HVAC guy. He's pretty busy. No problem, we got plenty of sweaters. Ha. He makes it out early the next week.

epriestley added a comment to T13688: How do you reasonably plumb a 1/4" drain line into a 1-1/4" drain pipe?.

I can't see a way to make the trap be any less garbage than it is because the 4" flanged tailpipe (the shortest flanged 1-1/4" tailpipe I could find) plus an additional 8" of tailpipe underneath it (the only 1-1/4" branch tailpipe I could find, which is only available with a slip fitting) means that the bottom of the lower tailpipe is super low. It looks like I left an extra 6" of flexible pipe on the drain side for fun, but that's just the rigid bottom of the tailpipe plus the minimum bend radius without making the flexible pipe start to crimp -- the bottom of the tailpipe is like 1-1/2" below the black plastic retainer clip.

epriestley added a comment to T13688: How do you reasonably plumb a 1/4" drain line into a 1-1/4" drain pipe?.

Since there's no fresh water supply to the dehumidifier I don't think there's much benefit to an air gap, as there's no way backflow could ever contaminate a supply line. A clogged sink drain could possibly drain sink water out through the dehumidifier bucket, but the top of the drain line is only ~1"-2" below the top of the sink so it would overflow the basin onto the floor before very long anyway.

An earlier patch here (rCORE6d6170f76463) swapped binlogs to MIXED and set a 24-hour retention policy. This issue has not reoccurred in the cluster since that patch went out, but the root causes remain unresolved.

epriestley closed T13686: Disable Ubuntu unattended upgrades as Resolved.

I patched and partially deployed this in early August. Another unattended MySQL upgrade went out on Monday night, also didn't restart MySQL on affected hosts, and caused some downtime on hosts that didn't have the patch (to "disable unattended upgrades"). I've now deployed this everywhere, and am presuming this is fixed until evidence arises to the contrary.

That's very likely the same problem, and I think it should be fixed by updating to the current stable (rPf2a7db1 or newer).
