Sprinkler board mounted to old Raspberry Pi B2. The USB dongle is a wifi transceiver. I really don’t want to run ethernet to our closet under the stairs.
And I went to run the zones that do work only to find the ancient controller has died. I’ve got a spare raspberry pi that should do the job along with an OpenSprinkler hat.
This weekend was spent in the dirt trying to find a sprinkler system leak. One zone’s heads leaked lots of water onto the sidewalk without coming up. Replaced some obvious ones, meaured water pressure both nearby and dug out the suspect valve to use the pressure gauge on it. Finally caped all the heads all off. That revealed two old sprayers that I replaced. I hope I can put all the sprayers back tonight and all will work.
I don't understand why more people don't bike. Dude took the time to open his window and shout something at me. How dare I ride down the middle of the road with a bright flashing white light.
what should have been 10 minutes to lube derailleur pulley bushings turned into a multi hour overhaul. I didnt realize this derailleur had nothing holding the cage spring tension except interference with the rest of the body. The spring let go and got quite stuck. This was on my cargo bike which complicates things. it is so heavy i can’t put it in a workstand. I also found I once routed the chain wrong. I ended up having to take the spring and clutch assembly apart twice.
I don’t know what I’ll do with it but here’s the viscous coupling portion of the differential minus all the stinky goo. The goo spaces the plates enough across the center splines
I finally took a few minutes to disassemble the old center differential from our Subaru; and sweet noodly appendage, the smell, the horrible smell of burnt viscous coupling fluid. Gear oil smells horrible. Worn out gear oil smells horrible plus some describe it as dead animal. This ads another layer of perhaps burnt dead animal.
If smell-o-vision were a thing this is the smell I would send to my enemies.
First picture shows the plates and spacers. The fluid is supposed to couple them together.
It's a happy day here this morning. DPS school choice stuff came out and kiddo gets to go to his preferred school next year, East HS, along with his close friends. They have a number of great things that will be great for him including a crazy number of foreign language classes and a mountain bike team. Don't know if he'll do either of those things, but I can hope.
Wifey got freaked out yesterday seeing something gross in the kitchen sink and called me over. It was little bits of yellow sponge shaved off when cleaning very sharp knives. You can imagine what that might look like.
The child had a teacher in service day yesterday. I had him do some yard work - seeding an area of the back yard where grass isn't growing so well. It's probably a little early to do that work, but whatever. He didn't seem to protest quite as much as having him help in the garage. Then again, I gave him more notice than a sudden, "Hey come help me the garage". Ah, teenagers.
It’s in. Getting the assembly into place under the car was a challenge without smearing the anerobic sealant. The housing and a ripped glove looked like quite the murder scene but it was only a little smeared sealant. In person this stuff looks a lot like the fake blood I remember from Halloween as a kid. Only the drive shaft and exhaust left.
I decided to take my time and vegged out to the last episode of True Detective last night. I’m now almost ready to put the assembly back onto the transmission housing. This bit seemed sketchy - using part of a jack handle - but it worked great.
