Thanks for going through some mess. Now i want to hack carts lol

I like the dirt. I've always enjoyed taking stuff apart to see how it works. You don't need a perfectly sterile laboratory environment for something that's destined for the trash bin anyways. I like that all the relevant parts of the discovery process to get it open are included. Nice little breakdown of the mechanical functions. And data sheets! 😁 Nice vid. 👍

4:56 that’s probably the little motor inside of it

It actually is pretty well sealed considering you say it has sat on a shelf for a year plus and still has water in it. If it was not well sealed then air and water could enter and exit easily. Judging by the mud it was m9re than likely submerged at some point. 😉 yours truly. SgtSteamer

This is criminally under-watched for how well-made it is. Your videos have a bigclive vibe to them in the best way. I was working on something else while watching this, apologies if anything below is something you mentioned in the video. I had always assumed those little plastic bits would contain small RF or NFC circuits that could be used to make modifications to how the lock operates; or, more likely, they open up a space that something could be 'plugged' into for that purpose. That would allow the sealed wheel to be adjusted on the fly at the end user location, and could be used in environments that are more rough than conventional electronics can stand up to. I didn't really see anything that looked like the right hardware to interface with something like that, but I am not knowledgeable enough on the hardware side of things to say. Notably, though, it doesn't look like replacements for those two parts are readily available. Not to the same extent as other parts for that wheel, at least. I looked into these a bit more and found them to be fascinating little devices. I can't be entirely sure, but I have a suspicion that the magnet and hall sensor are actually something of a safety system; by only powering the circuit a short bit at a time, you could slowly lock the wheel over the course of a few seconds or so depending on how quickly the cart is moving. This would help prevent any potential liability issues if someone were to get flipped or otherwise injured when the wheels suddenly lock on them. Gatekeeper seems to reference this 'slow stop' as a feature, but unfortunately don't specify any further. Most interesting to me -- although this could be common, I can't say I'm a locking wheel expert -- is that these are designed to automatically unlock when pulled back into the radius of the underground antenna. I was under the impression that such wheels would need to be manually unlocked, either physically or electronically.

Thanks for the positive comment! Yeah, there's nothing obvious inside that would make sense for those two removable colored caps, so still no clue what they could be for. Maybe it was for some feature that's not implemented on that particular model wheel. As for the magnet and hall sensor, you may be right. The older style wheel didn't have any way to know how fast the wheel was rotating and would just lock immediately at the boundary. I do remember seeing the older wheels at a local Target store many years ago, and when people would occasionally push the carts too far, they'd practically crash into it due to how fast it locked. As for the automatic unlocking with a second antenna in the ground, I did see that mentioned on their website, but that appears to be a feature that was introduced later on. The first wheels I had seen required a store employee to bring a remote up to the cart to unlock it.
