Idk. I’ve been using my ender 3 v1 without an ABL probe of any kind just fine. The main problems occur when the shitty stock buildplate (the super thin buildtak one held on with binder clips) warps under high heat and you have to contend with high spots. Getting a probe could have solved the problem, but I just swapped over to a magnetic spring steel PEI buildplate, and after a bit of live leveling, I’ve printed things using the full buildplate once or twice so far with proper adhesion throughout. The only thing that I needed to do to use that was to stick a magnetic sticker on the stock aluminum bed. If OP needs a link, this is the kit I bought: https://www.amazon.com/Magnetic-Flexible-Heated-235x235mm-Ender/dp/B07XBM24HN

Would an ABL sensor be nice to have? Absolutely. But you can technically do without it if your buildplate isn’t warped and you are very good at live leveling.

Oh, I also have the stiffer yellow springs installed, which helps the bed stay more level than the stock springs. That probably helps as well.

Apparently, pop tarts without frosting are a thing… They are probably still really sugary even without the frosting.

Oh FreeCAD definitely works in strange ways, mainly in the UX department, where it still needs work (kinda like GIMP does). Building a model in a broad sense is similar to solidworks (sketches extruded to 3d, cutting off material from there, etc), but understanding which workbench does what and navigating things is kind of a pain, even now.

Then again, it was similarly frustrating when I had to use fusion 360 instead of solidworks for a project. CAD programs are generally complex pieces of software, so it isn’t surprising that switching to one you aren’t familiar with really slows you down.

Only way I’ve found to get solidworks to run on Linux is to run a windows 11 VM using virtual machine manager (VMM). Ideally with GPU passthrough, among other optimizations. Kind of runs like shit on my Thinkpad T580 though, which is to be expected for an 8th gen quad core i5 laptop from 2018…

I’ve tried FreeCAD recently, and it isn’t that bad. The latest updates (v1.0 and beyond) have made it much better than it used to be. It helps to watch video guides, as the workflows are a little different. I found this one to be helpful: https://youtube.com/watch?v=9cqs3oTzpac

For what it’s worth, lots of phones these days are pretty aggressive with automatic post processing of photos, so the photo could be real (ie not AI generated or edited intentionally with AI) assuming the phone has a lower quality camera sensor with bad detail.

Others already addressed battery cost, so I will address charging time:

For modern EVs, charging time is basically a non-issue outside of longer road trips. Most EV owners utilize a slower (level 1 or level 2) charging station at home, which allows them to charge the car while they are at home/sleeping. EV owners can also use charging stations near/at their destination to charge while they are doing other things anyway. And assuming your daily commute isn’t like 100 miles/160 km, you really don’t need to stop at charging stations at all besides the one at home, which is cheaper. Obviously this does not apply if you rent a house or live in an apartment, etc.

Even road trips aren’t so bad assuming the car has an 800 volt battery pack instead of a 400 volt (higher voltage at same current = more power to charge and faster charge time). It also helps a lot if you only charge to 80 percent instead of 100 because that last 20 percent almost doubles your charge time and is harder on the battery. A lot of new EV owners don’t understand this and get frustrated when they are sitting there for 40 minutes getting almost no additional range compared to waiting for 20 minutes.

Let’s assume Costco size hot dogs (1/4 lb, or 0.11 kg), with an internal temp increase from fridge temperatures (37 F, or 276 K) to 165 F (347 K). Let’s also assume the heat capacity of the hot dog is about 3000 J/kg*K. To heat up a single hot dog takes this much energy:

q=mc*deltaT => q=(0.11 kg)*(3000 J/kg*K)*(347K-276K)=23,430 J of energy.

The heat capacity here is 9GW. That is 9 gigajoules of energy per second, or 9 billion joules every second. Divide this by the number of joules to cook each hot dog gets us the number of hot dogs that could be cooked every second:

9,000,000,000/23,430=384,123 hot dogs/second

With this hot dogs per second figure, we can find how long this energy source would take to feed the entire US population a Costco hot dog.

342,000,000 people/384,123 hot dogs per sec=890 seconds

Converting this to minutes:

890/60=14.8 minutes

So, this source of energy could feed the entire population of the US a Costco hot dog in less than 15 minutes if properly harnessed.
