nstead of tossing a cracked smartphone into an e-waste drawer, independent maker Gadget Industry found a far more ingenious use: gutting a Samsung Galaxy S21 5G and cramming its entire logic board directly inside an ordinary wireless mouse shell. The result is a fully functional, self-contained micro-PC that literally hides in the palm of your hand.
Squeezing flagship silicon into an everyday peripheral proved surprisingly practical once the bulky internal battery compartment was cleared out. To tame the Snapdragon processor under load, the builder engineered a custom brass heat spreader right inside the mouse chassis. Crucially, keeping the stock Samsung board eliminates the typical DIY headache of tinkering with Linux or flashing PostmarketOS—the device natively launches Samsung DeX as soon as you plug it into an external monitor over USB-C.
This oddball rig cuts through the usual tech waste cycle by offering a genuine blueprint for salvaging shattered high-end handsets. Instead of paying hundreds for an underpowered mini-PC stick, you get a zero-footprint desktop workstation tucked inside the very mouse you use to navigate it.
