Great video, always Nice to see the progress and steps when others are trying to reverse engineer stuff. Keep up the good work - would be great to see part 2 👍
Wow that is a really informative video thank you. I doubt that I could actually do it myself nor could I write the code to make it do anything different but I now understand what is involved which is the level I like
Exactly, having essentially a complete controller, memory, sensors, and Bluetooth radio that's intended to go in the trash after 90 days is ridiculous and the ultimate in landfill abuse. At a minimum, they should be traded back in for a large credit towards the next device so they can be recycled.
I don't understand why that button cell battery can not be replaced? Just desolder it and solder in a replacement, no? BTW Very cool summary on modifying chips, sensors. All new to me. Complicated, to be sure, but fascinating. Now on to part 2.
it is indeed possible, but you need to have their subscription based app to be able to use it. I didn't have any of those.. also some manufacturers just blocks the firmware after battery gets empty.
@@makersfunduckalso possible that the manufacturer stored some important information, like an AES key in RAM, making the device unusable after losing power. When Bluetooth is on, that device sucks about 20mA, but sleep mode is 1uA. It's an 8051 core too.
Very informative! I would like to know if you could read what is in the board. It would be nice to have the ability to use these sensors as is for monitoring store rooms. It would be interesting to see if one could assemble a receiver cheaply for these devices. More than likely the manufacture has the high price on the receiver logger unit since the sensors are disposable. Batteries are easy to replace and one could easily fit a socket within the housing to make battery replacement a breeze.
my best tip is, find a simple device which works with a programmable MCU, and upload your own simple code on it. afterwards, write your own firmware (read sensors etc.). it is a fun process, and you learn a lot. you can also watch the second part of this video here: ua-cam.com/video/nyylIe8ugiQ/v-deo.html
Which functionality do you think worths hacking? It is true that IOS limits users on many instances, so thats why there is a thing called "Jail Break" which removes those restrictions, and you can even install android on apple devices. but on that point, you can just use an android phone with the same specs, and would be happier :)

Thanks 👍
Awesome! I think I'll play this video quite some times in the future 🤓
Thanks!
Glad you liked it :)
I learned a couple of interesting things in this video, thank you! A second part would be interesting 👍
Glad you enjoyed it!
cool vid. also great tip with the gimp software!! thanks :)
Happy to help :)
Thanks for your explanation and I wait for the next video
You are welcome

How are disposable electronics not illegal yet?
indeed. it is a big problem for the modern society, and hope to see some progressive regulations about this issue worldwide.

Amazing 🤩
Thanks 🤗
This verry cool, i am a beginner in reverse engineering. Do you have tips where to start?

@@makersfunduck thanks great tip
Part 2 would be awesome. Can you rip the original code from the device?
Now part 2 is ready :)

nice
Thanks
Of course is easier for an engineer to rev
CAN YOU DO THIS WITH A WOOTING 60he
I dont have it. is it a cool keyboard?
So when do you hack a iPhone then? 😂

datashit :))))
So true.. Looking after the datasheets is the most trustable way:)
