[juskim] wished to construct a tiny mouse, nevertheless it couldn’t simply be any mouse. It needed to be a high-tech gaming mouse that might compete with the perfect on uncooked efficiency. The outcomes are spectacular, even when the ultimate construct is probably lower than ideally suited for pro-level gameplay.
The construct riffs on an earlier construct from [juskim] that used little greater than a PCB and a 3D-printed housing to make a barebones skeleton mouse. Nevertheless, this one ups the sophistication stage. On the coronary heart of the construct is the nRF54L15 microcontroller, which is paired with a PAW3395 mouse sensor which is often utilized in high-end gaming mice. It gives decision as much as 26K DPI for correct monitoring, speeds as much as 650 ips, and eight kHz sampling charges. Lengthy story brief, if you’d like fantastic twitch management, that is the sensor you’re in search of. The sensor and microcontroller are laced collectively on a customized PCB with a few buttons, a battery, and a charging circuit, and put in in a barebones 3D-printed housing to make the ultimate construct as small as doable.
The one actual factor letting the design down is the mouse’s key function—the scale. There’s little or no physique to seize on to and it’s onerous to think about with the ability to play most fast-paced video games at a excessive stage with such a tiny machine. However, the specs are hardcore and succesful, even when the enclosure isn’t.
[juskim] loves constructing tiny peripherals; we’ve featured his fantastic work earlier than, too. Video after the break.
