A gasoline based ICE is so incredibly inefficient it needs to shed heat or it would melt down. It makes more heat than that it makes motive power (the thing it is designed to do...). A 50 KW engine makes 200 KW(!!) of heat (at full throttle). Most of that heat energy exits the system through the exhaust gases but there is plenty that gets stuck in the body of the engine and you need to remove it from there somehow be…

I'd like to add that ICEs need to run hot to minimize cylinder wall heat losses and allow more of the explosion to be converted into work instead of heat, although too hot and they break of course. Ideally the engine block would be at the same temperature as the combustion temperature, but we don't have the materials to achieve that yet.

There have been some experiments with uncooled diesels that almost made it.

This reminded me of the SmartKnob View I saw on YT a while back, it's a knob built on a burshless motor that's controlled to provide the user with software defined feedback like tactile clicks and end stops

Back when I watched more F1 racing they had a musical performance where they used the telematic systems of some cars, with their high revving motors, to play notes ie the telematics selectively. I couldn't readily find a reference but remember the event.

Maybe this is what you're referring to. There are similar examples where people do this with old disk drives and printers too.

Hm... too many projects :) And that list is only getting longer, I think I'll pass it on to my kids. Right now (and for the past couple of years) it has been mostly music but also still some more interesting tools to play with. Currently making a set of super realistic traffic lights for my youngest including pedestrian crossing and automatic cycle influencing (road coil pickup to detect car presence in front of the…

Oh cool, not to further derail this thread but the music direction is interesting. I've also just gotten (back) into music production using an MPC One+ and I used https://www.audiblegenius.com/ for music theory+ear training. A frequent theme I've noticed in Youtube tutorials is a ton of >35 software engineers mentioning they are getting into music and feeling the need to say how old they are, as I guess the meme is l…

So, you're officially an influencer now, I bought the course. Very high quality material, a ton of work must have gone into that. I hope to get my own stuff up to that level of polish, it certainly sets an example.

I think I would happily pay money for an archive of high-quality recordings of what various problems sound like, in a variety of cars. It would really be nice not to have to go in and try to imitate the sound to my mechanic, and it would help give me an idea what the repair ought to cost. I've spent thousands of dollars on misdiagnosed (or misrepresented) "repairs," and it would be great to get a diagnosis from the m…

https://youtu.be/RKT-sKtR970 Check out this engine sound simulator. Perhaps a preconfiguration of this?

That would be a great help!...whenever it's an engine issue. Or when it's a failure of one of the parts of the engine.

Recent sounds I've tried to imitate have included "I got a bad tank of gas that was 20% water, and it's January in New England, and ice is pinging around," "I think my muffler has a leak," and "Maybe one of my wheel bearings is going bad?"

I drive a 17-year-old car with 225k miles on it because I don't want to drive anything made after the advent of smartphones, so I get to make lots of funny noises. The muffler one and the wheel bearing seem like they should have been findable!

Tesla cars, including the Cybertruck, are much less likely to run over things, including kids, than most every other vehicle. There are distance sensors around the entire perimeter of the car that give you a visual and audio queue for when you're close to stuff, and there's cameras that also cover 360 degrees that show pedestrians and other obstacles on the navigation screen. The people at Tesla have a lot of fun eve…

> There are distance sensors around the entire perimeter of the car Those have been gone a while. Just cameras now, and a lot of the functionality we had on earlier Teslas still lags behind on the newer camera-only cars. If you want ultrasonic sensors and full 360 degree camera, you have to get something more advanced, like a Nissan Rogue. No joke ;-). Tesla does not offer this ability.

My mistake. My model 3 gives this feedback and I assumed it was a sensor other than camera

Same, it immediately crashes upon loading. On Windows with Chrome 119.0.6045.160 [Edit] Figured out Dark Reader extension is causing the crash. I turned it off for that specific site and it no longer crashes. Very strange.

Same here. I've had other weird interactions with Dark Reader before - one was where minecraft.net refused to let me log in until I turned off Dark Reader.

I always get Access Denied errors when using dark reader on pages hosted by Akamai

Even more off-topic, but something I’m struggling with personally: how do you find the time for projects, with kids in the picture? Me, I can just barely eke out a truncated workday, then it’s kids and housework until the kids go to sleep and maybe 1.5 hours of time until bed, which mostly I spend with my partner. So I see people with diverse interests and kids and I just wonder: how!

Hm, that's a hard one. I try to involve my kids in them, this doesn't always work, but when it does it is fantastic. I'm also an insomniac (it's 7:20 am here and I'm still awake...) so I have a ton of time when everybody is asleep (that's when I do most of my coding and reading), and when everybody is off to school I catch up on sleep. Not ideal but it mostly works. Another nice-to-have is that I can make ends meet w…

Yup, the trick with kids is simply staying up later. I usually do a couple 2 to 4am nights for freelance work, then do an early bed night, then repeat. Waking up at 7 to take the kids to school is a little rough, but a stop at the coffee shops always fixes that.

I'm pretty sure this is exactly it. Thank you!
