| > The updater device then sends 64 byte chunks spread over 9 CAN 0x384 frames Classic CAN uses 8 bytes long frame, so 64 bits. Is it a typo in the post, vor is it using CAN-FD? |

| Thank you for posting! I got a e-scooter this spring and wrote my own app for it after reverse engineering the official app + BLE logs. I am not brave enough to do anything with the firmware on it though. Maybe not yet at least |

| Wish I was brainy enough to do this sort of thing! |

| ▲ | j_m_b an hour ago | parent [-] | | That's what is nice about LLMs. You CAN do these things now! | | |
| ▲ | wkjagt an hour ago | parent | next [-] | | Maybe I'm out of touch with the times, but I wouldn't feel safe riding an e-scooter with custom vibe coded firmware. | | |
| ▲ | GuB-42 27 minutes ago | parent | next [-] | | What make you think it is vibe coded? There is no mention of genAI being used, and the methodology looks more consistent with hand-written code he actually understands. | |
| ▲ | IshKebab 37 minutes ago | parent | prev | next [-] | | You don't have to fully vibe code it. Most of this stuff doesn't take massive brains, it is just super tedious - especially the reverse engineering. I've never really had the patience for that (except one USB devices that I did reverse engineer when I was younger). AI really helps with the tedium. | |
| ▲ | m00dy 41 minutes ago | parent | prev [-] | | If it is coded in safe Rust, why not ? | | |
| ▲ | malnourish 35 minutes ago | parent [-] | | Safe rust does not mean correct logic; best not conflate the two. You could have perfectly safe rust that disables brakes above a certain speed, inverts steering by wire, or adjusts the charging parameters, for example (depending on addressable capabilities). |

| ▲ | spaqin 13 minutes ago | parent | prev | next [-] | | So you're still not brainy enough to do it, but the LLM can. I mean. Sort of? The LLM won't go into checking random USB-C connections with an oscilloscope - it doesn't have hands, for one. | |

| Very nice. Be safe out there when tweaking these things. |

| ▲ | TheChaplain 2 hours ago | parent [-] | | From what I've seen on the streets, people bypassing the restrictions will not, and there will be injuries. | | |
| ▲ | jstanley 2 hours ago | parent [-] | | You only notice the ones that aren't safe. How would you know if someone bypassed the restrictions if they were riding it safely? |
