This week, a Tesla owner retrofits his 2022 Model 3 with Ai4 hardware, Tesla is set to launch Cybercab in the next week while Rivian just gave owners their most requested feature.
Kim JavaHosthave.
It looks like there might actually be a way if you have a hardware 3 vehicle to upgrade it, maybe do a DIY to get hardware 4.
That's right.
They've taken the hardware 3 out of that vehicle.
They've brought in a 2026 Model Y, brought the Juniper parts in, and were able to make this Model 3 become hardware 4. and also give features, self-driving features that would be identical, very close to what you'd get out of a hardware four car.
One is, where did they get the Juniper vehicle from? Because are you now buying two vehicles to be able to get better hardware in your car? And two, who is this guy? Like, is he just some random guy? Obviously, he knows what he's
He knows what he's doing a little bit.
Yeah.
So his name is Mike Kapinski, and he actually is a software engineer by trade.
He says he's a tinkerer by heart.
So he decided to do this a few months ago.
He said it was relatively easy.
It took him a few months because he was going between his day job and being able to kind of tap into removing parts and adding parts to this vehicle.
By the way, his background again, he's created a software called Tesla Android, which hacks into your UI, allows you to have feature-rich access to your center screen, bring in additional customized features on your center screen.
I'm curious if anyone's
He says he got the AI4 computer in there, swapped out the first camera, and what he learned is you absolutely need to replace all eight cameras inside the car as well for it to properly be able to function.
It's not just the hardware for computer, but the findings on this are fascinating because it showed that all of the cables can remain put, just the hardware comes in, adapters allow them to interact with the new hardware, so you don't need to swap out wiring or any sort of drilling or cutting.
