What's Happening?
A Reddit user, known as krausler, has engineered a computer that is the size of a credit card, named the Muxcard. This device measures only 1 mm in depth and includes features such as Wi-Fi, low-energy Bluetooth, an E-Paper display, an accelerometer,
and an NFC reader. The creation of the Muxcard involved significant engineering challenges, particularly in maintaining mechanical stability and managing material fatigue. The main chip used is an ESP32-C3FH4, and it is powered by an ultra-thin lithium polymer battery. Despite its small size, the Muxcard is considered a functional computer, although krausler acknowledges that the term 'computer' might be an overstatement.
Why It's Important?
The development of the Muxcard highlights the potential for innovation in miniaturized computing technology. This could have significant implications for industries focused on portable and wearable technology, as well as for hobbyists and developers interested in compact computing solutions. The project demonstrates the possibilities of creating functional devices with minimal physical footprint, which could lead to advancements in personal electronics and Internet of Things (IoT) applications. The challenges faced in the engineering process also provide insights into the complexities of designing ultra-thin devices, which could inform future developments in the field.
