The first post in what we’re sure will be a fascinating series deals with dumping the board’s firmware using the GreatFET. The chipset it uses has already been fairly well explored (and exploited) by security researchers, but the goal here was more about gaining some practical hands-on experience than it was breaking any new ground. Looking to hone his hardware hacking skills, recently set out to reverse engineer a common cheap wireless keyboard: the Logitech K360. Posted in Peripherals Hacks Tagged camera, g402, gaming, gui, image, linux, logitech, mouse, stm32 It is much improved on older mouse-camera builds we’ve seen, though, thanks to the high performance sensors in gaming mice. But as a proof-of-concept project this high-performance mouse does work fairly well as a camera, albeit with a very low resolution by modern digital camera standards.
It’s probably best to not attempt this project if you plan to re-use the mouse, as the custom firmware appears to render the mouse useless as an actual mouse. created a custom USB vendor-specific endpoint and wrote a Linux kernel module to parse the data into a custom GUI program that can display the image captured by the mouse sensor on-screen. Normally this is processed internally in the mouse to translate movement into cursor motion, but this mouse conveniently has a familiar STM32 processor with an SPI interface already broken out on the PCB that could be quickly connected to in order to gather image data. As we’ve seen before, it is possible to convert this mechanism into an actual camera, but until now we haven’t seen something like this on a high-performance mouse designed for FPS gaming.įor this project is disassembling the Logitech G402, a popular gaming mouse with up to 4000 dpi.
They do this by using what is essentially a tiny digital camera to monitor changes in motion. Ever since the world decided to transition from mechanical ball mice to optical mice, we have been blessed with computer pointing devices that don’t need regular cleaning and have much better performance than their ancestors.
