Hey this looks neat, I’ve been thinking on trying something similar. I’ve not encountered the ANT protocol, what bike ya using? Is it a higher level thing that your display is giving you, or something your controller uses? I know Bafang uses CAN protocols in their newer e-bike systems and a lot of manufacturers (especially Chinese) use a proprietary UART protocol to stitch things together on the cheaper end.
The mess of different implementations makes it really hard to hack on and share this kinda stuff.
AI does make it really easy to figure out these protocols now so that’s nice I guess. I just flipped my bike upside down and hooked up a logic analyzer and it took LLM no time to figure it out… it is really impressive
ANT+ is basically dead because of an EU legal requirement to ensure that personal information is encrypted. So no new devices will be supporting it, and everything has to move to BLE.
It was quite a rich ecosystem of sensor devices, especially for cycling, including speed and cadence sensors, heart rate monitors, power meters, lights, radar, etc.
It has been extremely popular over the last 20 years.
what is insane, is that ble is largely unsecured in modern implementations. when testing, i kept picking up everyones whoops/assorted ble devices spamming out heart rate data to whomever wanted to connect.
You don't need AI to decode these protocols. People have already done that. If you look a bit further than asking you favourite LLM for obvious answers there is plenty of OS code available for the LS, KT and Bafang uart protocols. Still recommend you avoid them, they are pretty poor and CAN is way more reliable.
They are both using the same physical layer, but the ANT+ protocol scheme is more amenable to ultra-low-power implementations than BLE is. The European belief that my wheel rotation sensor needs privacy through encryption has effectively outlawed the low-power attributes of ANT+ for future hardware.
Can you cite a source for that one? Of the 25 fatalities in sf in 2025 all but two were someone driving a car, truck, or van.
Of the two others, one was a scooter operator striking and elderly person, and then the other was an elderly person on a mobility device swerving out of the way of pedestrians crossing against the light. Zero bus accidents involving pedestrian fatalities.
I believe that their was one bus fatality this year, but of 12 total, I haven't looked up the causes of those accidents yet but I'd guess that the majority of them are going to be caused by drivers as well.
I've been doing Doordash on an e-bike in the city over the last year and a half. The toothpaste is locked up because groups of people were just going into stores with garbage bags, filling them, and walking out. I saw three in one day once. It was really chronic for a little while. Prop 36 passed and criminalized that kind of group theft, and then it all but stopped early this year, but retail hasn't caught up to this fact yet, and probably wont ever.
I think pretty much everyone agrees though that peoples habits have just changed with work from home. The cost of having to wait on an employee has been externalized to people shopping for a living in batch orders, and those people don't mind waiting given that we're only paid for minutes that we're actively on an order (Prop 22).
So yeah, retails not completely dead, just serves a different audience now.
Ah nice demo! I flew around SF for way too long just enjoying the sights. On my M3 Air using Chrome it eventually just turns into blobs and my character get stuck, takes about twenty minutes. I popped open the DevTools and the game loads in at like 400mb but after five or so minutes I'm at 2GB of memory consumption. I'd guess that you need to have your agent do a couple of passes for memory leaks. Very fun otherwise!
You're spot on, I've been doing Doordash on an e-bike on the weekends for exercise and the wait times are BS because everyone orders lunch/dinner at the same time and they're in essentially a random queue with everyone else who orders. Add to that multiple pick ups and drop offs and you've got a mess.
Talking to people really does help though, everyone wants to be more forgiving when you remind them theirs a human factor involved in getting the food to them.
The last time I upgraded my networking setup (just as the pandemic started) I went with Ubiquiti, shortly after (before?) they started default forcing you to sign up for their cloud service to use the router, you can switch it to a locally operated mode after you sign up but they bury it in the options. Their networking equipment works great, don't get me wrong, but they don't open source anything. I keep waiting for the full rug pull when sales start to slow because everything they release is rock solid and everything I have is "good enough." I don't feel the need to upgrade for as long as the rug pull doesn't happen.
I am super grateful people are starting to work on open source solutions to this stuff :).
I did a DSL to facilitate this at https://prlang.com. I've had some success setting up agents to "act" out scenes, where each plays a different part, but it was kinda limited in that conversations would kinda de cohere into nonsense after a bit.
I don't know about Cruise but Waymo has a training video[1] that shows a first responder hitting a button to contact dispatch, then explaining that they're a first responder and they need to move a vehicle, and finally being given control. It looks like the process could take 30 seconds in the best case scenario, which is likely too long in many life or death scenarios, but they do at least have a process.
Good, but in a poor reception area, or in an earthquake or more conventional cell network outage situation, a link to the control center may not be accessible.
This seems like pretty a straightforward, but overlooked systems engineering concern.
Yeah I think we're in agreement that the current solution is not very good. I can understand why they opted for it initially though, given the thing that happened with protesters putting traffic cones on AV's to disable them. Imagine if instead of doing that, protesters hijacked cars and drove them into situations where the AV couldn't easily navigate out of, like driving up onto sidewalks for instance. The bombastic headlines write themselves. In the end I bet they end up making a kind of "master key" that works with all AV's to distribute among first responders. I'm in the "it'll get sorted out eventually" camp on this one.
At this point autonomous cars have been in multiple incidents that have blocked traffic, impeded emergency access vehicles, and now sat on top of accident victims. I understand it can be tricky with multiple human orgs and interactions in play but, the time to sort it out is now at limited scale. It only gets harder to implement reasonable standards later.
A rolling camera laden sensor platform seems like a poor target for vandalism - a simple label with: recording starts when emergency controls are accessed would seem to discourage most & the car doesn't need to move fast or far for emergency situations.
This looks neat, but isn't it already implemented natively in Chrome? You can go into the Network tab in the Chrome Dev Tools and right click a request in the "Name" list, go to "copy", then "Copy as cURL". It'd probably be easier to use CnTUI if you wanted to bulk resend requests that Chrome's making though.
Yeah I'll raise my hand here to say I did a file manager that automates file management tasks by using AI to write Bash scripts (Aerome.net). It's still super primitive though, if I'm being honest. I think the problem is that it's way harder to write a cross platform file manager, or browser wrapper in your case, then it is to write a chat interface on top of ChatGPT. I suspect in a year or two many good use cases will emerge, as people write more complicated software to take advantage of LLM's capabilities.
I'm going to check out you're browser thing later tonight, it looks good!
