Hmmm, the other person was me. I actually did most of the work on reverse engineering the protocol, figured out the baud rate, a lot of the data and the checksum. Then someone else did a video on it, before I did... I even wrote code on the Arduino to talk to the battery by modifying the Softserial library, and saw the only communication seems to be between the battery and the charger. The tools don't seem to communicate.
Yeah my last HP printer that I bought I discovered I couldn't refill the cartridge myself and reuse it. The Printer wouldn't reinitialize like it was a new refill. I bought a refill, and when it was used up I put the whole thing in a dumpster and bought a different manufactures printer that hasn't implemented that BS. The whole "Right to repair" gets me going in a bad way. I refuse to buy a product that I can't repair and I suspect that's going to get harder to find.
if you actually compare OEM batteries to 3rd parties the 3rd parties are often objectively worse. Im sure the manufacturer takes a decent margin but they do also make their batteries to a high standard. It's always cheaper to produce shitty, lying batteries that kinda work, than it is to produce, proper, beefy, non lying batteries that do perform.
Way way back in time, several channels on my analog TV were all scrambled. So I looked at the baseband video of these channels with my TV converter box. The video was all there, but the horizontal sync pulses were raised upwards to the video image level, and so the TV could not detect them, hence the TV image was all out of wack. But for just $6 worth of parts, I made a circuit that would correct the positioning of the horizontal sync pulses. The circuit only required about 15ma at 12 Vdc and so I just put it inside my TV converter, thus using its 12 Vdc supply. Yep, so the cheap circuit fixed this little horizontal sync problem. Funny enough, those particular channels with the sync problem, were called PAY TV channels.
Re: Dewalt 20 Volt Max batteries, I have lots of 20 Volt Max tools and some batteries that are over 10 years old that still work great. I recently bought a new 5 Amp hour one and a chain saw, branch trimmer that both work really well and now I have bought Two 9 Amp Hour 60 volt/20 volt Flex batteries for their next gen tools. I only buy Dewalt tools, I even have a 20 volt Max Nailing gun that is awesome. I used to be a Framer/Carpenter for 12 years.
Mine worked great until the day I tried charging them, now they are junk. I was amazed that they lasted over 5 years without ever needing to charge them.
Love the show. Almost enough to turn on RUclips notifications for you!! How about that TETRA backdoor have you touched that one yet? Spooky implications, and just in time for Halloween!
It's only TEA1, a 32 bit key (30 years on, that's understandably hackable now). Essentially the export version for "unfriendly" states (from the EU perspective), so no effect on most users. AIUI, TEA2+ is 80 bit and is about to be upgraded to 192 bit.
Unfortunately, tools, especially power tools and battery powered tools are stolen A LOT. So much so that many tools have connectivity options built in for anti-theft. First, there is "store activation" - if you shoplift the tool from the store, it won't work because it won't be activated by the store. Next, most tools have Bluetooth as well to activate them by the legitimate owner - because having tools stolen at a job site is expected to happen. And it's not just some other contractor on the site - other people walk onto job sites and steal tools as well. So all the professional tools are connected because it's the only way to protect against theft. It would not surprise me if batteries adopted similar things because hey, it's something easy to steal as well. So avoiding tool connectivity is basically ensuring your tools aren't recovered if they get stolen. Now, in general, though, the tools don't have internet connectivity - because often the tools are used in places where there is no internet connectivity - sure you might be working on a house in the city, but there's no Wi-Fi around. There's cellular, but that's it. So chances are, it's not something that's happening because most tools will likely be used in places where connectivity is limited. The Bluetooth tools usually use some form of fob you keep on your person.
I can see your comment only when I switch the "sort by" to Newest First (instead of Top Comments) I switch when the displayed number of comments noticeably differs from the actual number of comments visible. I assume this is some variation of the concept of shadow banning(??) EDIT - once I replied, your comment now shows up normally for me regardless of sort option chosen. Odd.
@@sootikins for some reason top comments seems to only prioritize comments with engagement, which, makes sense given that its supposed to be the "top comments" i dont think its shadow banning, just a weird technicality of how comments are sorted.
i actually don't mind the Sony warning that the battery is not made by them warning, its been on my cameras for years, there are so many counter fit batteries on Amazon etc so its good to know yours is legit and if you do use 3rd party batteries it shows this warning once and that's it.
@@RECESSIM its nothing like that its just to warn users "The operation and safety of this battery cannot be guaranteed. Continue use?” cheap counterfeit batteries and 3rd party but they would never block use of 3rd party if it was about money they would block 3rd party lenses first printers etc they sell you the printer at cheaper price to get you in and then sell you over priced consumables
Yep. I used to see what I thought of as WiFi dialects a lot back in the early 802.11B/G/N days. Depending on the particular vendor firmware, different clients and access points might not even see each other let alone connect. Flashing alternate firmware would sometimes fix it. Nice to see the differences in detail.
to be fair with the batteries, non OEM batteries tend to be of worse quality, and often have worse safety features, which if you abuse your tools like most tend to, could lead to bad outcomes and or opinions on tools (with especially bad batteries) It's not like printer ink where its all pretty much the same.
The Milwaukee battery handshaking is NOT just so you buy their batteries. There are temperature and low voltage information being shared between the tool and battery keeping your investments from dieing permanently.
The voltage and temperature between tool and battery are purely analogue. I've not seen any communication between tool and battery. I didn't get around to doing a video on this, but I did make a few reddit posts with a lot of this information about 7 months ago, then someone else decided to make a video with my work.
Yooo I watch your vids mate. Good to see you here! I've made a few Bluetooth speakers mainly using 18650s and a few different configs of mini amps and whatnot but the most recent one is powered by a 4.0Ah Milwaukee M18 and it lasts around 24 hours at a more than decent volume. It's a Mission centre speaker off of surround sound and it kicks arse big time

Thaaankkk Yooouuu! I watched boffofem and checked the code. Love Ya.
I saw that video. He does mention you.
When I get the notification of a new Recessim video my productivity immediately drops. Which is great. Thank you !
Let's face the facts, your productivity was never that high to begin with! lol, jk

God forbid the manufacturers just made cost-effective batteries that weren't so expensive that 3rd parties wouldn't bother to try to 'fake'.....

8:05 I hear device fingerprinting and tracking. Sort of like the article Kody Kinzie did on tracking police using their smart holsters.

I seem to be having a similar problem. Any idea where a person might find a cut sheet, schematics and general assembly info?

heeheheh it would be fun to troll on gigapan by uploading chip images
I understand that comments boost the channel ... So totally OT: is last week's chip glitch likely to help progress the Smart Meter work?
It makes me realize I should pursue that path with damn near every device!
you need a rolex watch 😀

Audit the audit???
Thank you for the updates, all good stuff. I don't know which way to follow up! lol!
My week is now complete! More stuff to discover and understand.
your CUFFLINKS! so cool hehe
Late nite with recessim. This channels so og!

I only use the original Sony batteries so wasn’t an issue for me. But a warning can easily change to a “not authorized” by the manufacturer.
