A developer has constructed a remarkably skinny laptop that’s nearly the identical dimension and thickness as a regular bank card, probably opening the door to a brand new class of ultra-portable computing units.
Referred to as the “Muxcard,” the experimental machine combines a totally useful microcomputer, wi-fi connectivity, NFC help, sensors, and an E Ink show right into a physique measuring simply 1mm thick – skinny sufficient to suit inside a daily pockets alongside financial institution playing cards. The challenge, created by GitHub person “krauseler,” has shortly drawn consideration from the maker and {hardware} fanatic group for pushing the bodily limits of compact electronics.
A tiny laptop designed to slot in your pockets
Regardless of its slim kind issue, the Muxcard consists of surprisingly succesful {hardware}. The machine is powered by an ESP32-C3 microcontroller and integrates a 1.54-inch versatile E Ink show, NFC {hardware}, an IMU movement sensor, Bluetooth and Wi-Fi connectivity, and a miniature lithium-polymer battery.

The engineering problem was not merely shrinking elements, however making them sturdy sufficient to outlive on a regular basis bending and stress inside a pockets. In line with challenge particulars shared on-line, the creator used versatile PCBs and punctiliously separated delicate elements into “islands” related via bend-tolerant sections to scale back mechanical stress.
One of many largest hurdles concerned integrating the E Ink show into such a skinny machine. Conventional connectors had been reportedly too cumbersome, forcing the creator to hand-solder connections straight onto the show flex cable. Energy administration additionally grew to become a serious problem as a result of ultra-thin batteries supply extraordinarily restricted capability.
Why this issues past a DIY challenge
At first look, the Muxcard might look like a distinct segment experiment for hobbyists. Nevertheless, the challenge displays a broader development towards invisible and ambient computing – units changing into smaller, thinner, and extra seamlessly built-in into on a regular basis objects.

Using an E Ink display screen is especially vital as a result of it consumes nearly no energy whereas displaying static info, permitting the cardboard to stay useful for longer durations regardless of its tiny battery. The low-power design might make units like this appropriate for safe identification, digital enterprise playing cards, two-factor authentication techniques, occasion passes, or minimalist sensible residence controls.
For shoppers, initiatives just like the Muxcard supply a glimpse into how future computing units might evolve past telephones and wearables into objects individuals already carry day-after-day.
What comes subsequent
The Muxcard stays an experimental open-source challenge reasonably than a business product. Nevertheless, the {hardware} information and firmware have already been printed on-line for non-commercial use, that means builders and lovers can try and construct their very own variations.
As versatile electronics, skinny batteries, and low-power shows proceed enhancing, ideas just like the Muxcard might finally affect future digital IDs, safe authentication instruments, and ultra-portable computing units.
