Oh, Ikey. I love you, man, but we both know you're going to see something shiny next month and drop this like a hot potato and go completely dark.

Well, you see, it's somehow using AI and it's run by a dick.

What's not to love about it?

All the pedos are on Capitol Hill or in private jets.

Fuck Kentucky.

Is it for agriculture?

Imperial. Sorta.

I literally use units like mL per acre for something like boron application with fertilizer.

That's a lot of bread.

I've been a proponent of this for the last 18 months.

14,000 Euro entry point. This would be awesome to see in Canada. And it's not even Chinese.

I hope that's real brick behind that. I've seen some pretty gnarly damage from people using their BBQs too close to the side of the house.

I see he leaned left right before the end there. His fans should be outraged.

Fritz, are we the baddies?

My wife would shoot me if I cooked hers past blue rare. She wants it still mooing.

Sad to see him go but what an impact he's made over the last decade. Thanks, Morten!

I had an ECU for an air seeder blow up, so I'm rebuilding it from scratch using a Pi and other hardware. I got the shaft sensors reading fine, set up the relays and other switches and lights, but this one has stumped me. The markings give me nothing to go off of (Trison 91779847 Rev C gives me nothing useful), but I still have the borked board that I can trace out. The sensor is fed 12V and ground, and has a white wire that is marked for airspeed input on the wiring diagram of the ECU.

When I trace the white wire on this, it looks like it's conditioned by some diodes (two diodes, in opposite directions to ground) and a capacitor, with a pulldown resistor. The trace then goes to an opamp (TLC2272) inverted input via what looks like a voltage divider, and from there maybe feeds into the processor the board uses. Kind of hard to see from that point on.

I scoped it and if there's data there, it's in the 1-2mV range if I reference from ground, which makes the opamp make sense. But I don't have a very good scope where I am, I do have a Rigol at home that I could get.

I have built a very crude estimate of the airspeed just from the current draw of the hotwire using an ADC and shunt resistors, but I assume I can get a better reading from this sense wire if I can figure out how the hell it's working, via a reference circuit to help me understand. If you know this sensor or a similiar sensor that I can crib the circuit from, that would be awesome.

She called me because she couldn't get her car started after work. We had to get it towed out of the underground parking which is quite a pain in the ass apparently.

I spent a couple hours troubleshooting the issue (smoky exhaust, barely started, ran like shit) and I burned out the starter in the process and had to put a new one in. Starters in these little 3.7L engines are pretty pathetic.

At some point in all this she mentioned she had filled up before driving to work, so I figured out how to jumper the fuel pump and pumped out this piss-colored junk. Feels oily like diesel, doesn't burn explosively like you'd expect with straight gas.

Fresh fuel and some Seafoam snake oil to maybe clean injectors. Since I didn't drop the tank to clean it perfectly, she's going to put small amounts in for a few fills and burn it off completely between fills because the solution to pollution is dilution.

Her receipt showed she uses the gas pump, not the diesel, so I'm wondering how many people got to deal with this bullshit since I'm guessing the station got an entire compartment contaminated. Haven't bothered to talk to the company, since I did the work myself and they certainly aren't going to reimburse me for my time.

Ah well, it's an excuse to do a pile of other maintenance I'd planned anyway and had parts for.

Wife is happy she isn't buying a new car. Happy wife, happy life.
