No matter either it is earlier or late, end of the day, the reverse engineering is digging to device. It may be like that, if you try to keep an old equipment piece running, manufacturer get long defunct, also the parts are not available for long time.
It may be the sweet of the new router along with the firmware of lock down. Or, it may be a reason of your curiosity.
No one is caring about the reason, as the reverse engineering has become the rewarding endeavor. Some of the example of reverse engineering is like the spy novels. In that, the clock and the dagger is replaced by encryption and the soldering iron.
In this recent week, the hackers have focused on a number of great reverse engineering on the projects of Hackday.io!!
Let us start with the “[Henryk Plötz]” and the “Reverse-Engineering a low-cost USB CO2 monitor”. Carbon monoxide measurement and detection devices are the household safety item nowadays, also have become much cheap.
Carbon dioxide measurement devices are not so common for more expensive. The [Henryk] have found the device of around 80€, this can do what he needs.
It is Included with USB connector, which was just reason of power. When it is plugged in, this device get enumerated on the Linux box.
Accompanying software of windows displayed the live the detector data, but enough information was not there on this protocol. High time for busting out the Ida pro, so go town for the software! [Henryk] which battled with monitor software of CO₂ and also rewarded.
Then comes the “[Bob Blake]”and the “Reverse-Engineering the Maverick ET-732”. [Bob] loves the barbecue, but he hates to the babysit of his smoker. Gratefully there are the sensor of wireless temperature for the purpose, but there were limited range that you can’t get multiple receivers in the house. He, [Bob] aimed for fixing all by sending “Maverick wireless thermometer data” to web, thus he was able to check in his cooking anytime anywhere. Firstly he need to reverse engineer on the protocol by using the sensor.
An analyzer of spectrum told [Bob], the transmit frequency of the sensor was around 433.92 MHz, that is very common for a low-cost transmitter as like it. [Bob] had some of the compatible receivers on his office, thus he was able to take capture some of the data with the Saleae logic analyzer. Real fun was on figuring out the exact data!
