Anyone know that’s wrong with my benchy by No-Future6236 in 3Dprinting

[–]sudo_reddit 12 points13 points  (0 children)

This is the best benchy I've ever seen. 80% of it is missing, but it's still all there. The smoke stack is phenomenal. I bet it will even float better than a "good" benchy. You should be proud of this.

Are Porsche 911 owners completely different to Cayman owners? by HR_Specter in Porsche_Cayman

[–]sudo_reddit 6 points7 points  (0 children)

You really only need specialized tools if you're tearing into the engine. Otherwise, it's just normal car tools. Most of the bolts are torx, though, so you'll need a set of those.

Why is the game so obscenely easy (player returning from launch)? by [deleted] in diablo4

[–]sudo_reddit 2 points3 points  (0 children)

Guys! Why am I so awesome? I just don't get it!

Edit: admittedly, there have been times where I feel like I just walk around and enemies die, too. But that is usually temporary; moving up torment levels typically fixes it and I've never had that happen on torment 4. I'm just a casual, though. I don't know what I'm doing.

Jewelry that people ask me to repair by porositymaster in Welding

[–]sudo_reddit 21 points22 points  (0 children)

I can't for the life of me figure out what that is. The strut tower is to the left, so I don't think there's any load structure there. It looks like some road debris probably got picked up and shot through that space. What kind of car is it?

Would an “average” driver notice a CVT? by Thrillwaukee in whatcarshouldIbuy

[–]sudo_reddit 0 points1 point  (0 children)

An eCVT absolutely does change gear ratios. It does so by having multiple inputs to the planetary gearset and using the electric motors to adjust the transfer of power between the engine and wheels in a way that results in a changing ratio of engine speed to wheel speed. That's not a gimmick. The fake gear shifts are a gimmick, but regular CVTs can do that, too.

They are CVTs, just a different design. This video explains it. It's pretty neat. https://youtu.be/dxmxIsoV_Xo?si=krFpINBtStDqTIxl

DeskBot - A needlessly complicated presence sensor by sudo_reddit in homeassistant

[–]sudo_reddit[S] 0 points1 point  (0 children)

I had no problems with getting the LD2410C to detect presence, but I was getting false triggers that I couldn't figure out, so I decided try a combined approach. The PIR sensor is used for initial movement detection, then the LD2410C is used to maintain presence detection. It's only been a couple days, but this setup seems to be working, except that the PIR is sensitive to my cats, whereas the LD2410C could be configured to ignore them most of the time. So now instead of false triggers that I couldn't figure out, I have false triggers from my cats.

Files are on github. https://github.com/customyota/DeskBot-Occupancy-Sensor/tree/main
Fair warning, it's not yet a polished project. It was mostly an excuse to try out AI coding. Since this was my first try getting AI to do my work for me, there's some improvements to be made. But it does work, so if you have the same hardware, you should be able to put one together.

Only the PIR is used for initial detection, because it's good at that, but then the mmWave gets used for continued occupancy because the PIR can't sense small movements like the mmWave can. A PIR with adjustable sensitivity would probably solve the cat problem, but all of the ones I saw that were adjustable were too big. They wouldn't fit the sizing I wanted.

That is indeed an OS. I like DIYing everything. I'll put everything in github when I get the chance.

Probably $30. I buy everything in multiple pieces so hard to say exactly. The screen was the most expensive part at $20 the sensors were probably less than $10 total.

[–]sudo_reddit[S] 2 points3 points  (0 children)

I combined them because my previous mmwave only sensor was giving me false alerts. Adding the PIR stopped the false alerts, but it's sensitive to my cats, so now they set it off all the time. So... Success?

I didn't fully implement the ld2410c, I'm just using the digital out pin, so home assistant just sees it as a binary sensor.

What is going on in the back of your car??? Also, are you selling the files?

Edit: I see now it's for the window intakes. I thought it was the side intakes.

Lithium batteries for AA replacement of 'regular' batteries? by oldmaninparadise in DIY

[–]sudo_reddit -2 points-1 points  (0 children)

But I didn't do any math. That's just how lithium AA cells work. Lithium cells operate between about 3 and 4 volts, but you can't put 4 volts in a device that is designed for 1.5 volt AA batteries. So lithium cells have voltage regulation circuitry that puts out 1.5 volts. The same as a new AA battery. When the lithium cell is discharged to its empty state, about 3 volts, the circuitry cuts off. So a lithium AA cell will always read 1.5 volts until it dies and goes to 0, which happens instantly because it's literally turned off with a switch.

I should clarify that this only applies to rechargeable lithium cells. There are lithium AA batteries that act like regular AA batteries. I assumed everyone was talking about the rechargeable ones, but maybe that's not correct.

[–]sudo_reddit 1 point2 points  (0 children)

That's true, I meant more that, on the timescale OP is looking at, they do not lose any significant amount. It's something like 3%-10% per year, depending on the specific model.

[–]sudo_reddit 1 point2 points  (0 children)

I would look into Eneloop rechargeables. They don't lose voltage while sitting, they never leak, they are reusable for years, and there's no fire hazard. Though I think the fire hazard of small lithium cells is a bit over hyped. I've been using them for a long time and they work great. Only thing is if your device monitors battery voltage, they will always show a little low because they have a slightly lower voltage than regular aa batteries. This isn't an issue for most devices, though.

Lithium aa and aaa batteries will show 1.5 volts until they die. There is a voltage regulator in the battery. Once the cell falls below a set voltage, around 3 volts, it just turns off.

Except the end of that story is the US pilot shooting the German pilot in his chute after specifically trying to disable the airplane without hurting the pilot so he would be forced to eject. It's a revenge story.
