ESP32 Wifi Clock With WS2812

“Many times I woke up in the middle of the night and wanted to check the time. I need to turn on the lights or wake up the phone to view. When I turn on the light or phone, the …

Fabricating fully functional drones

“CSAIL’s “LaserFactory” system automates the full process for making functional devices in one system. From Star Trek’s replicators to Richie Rich’s wishing machine, popular culture has a long history of parading flashy machines that can instantly output …

Fatigue-free Layered Hybrid Perovskite Ferroelectric Developed for Photovoltaic Non-volatile Memories

“Ferroelectric materials with reversible spontaneous polarization have been extensively investigated as active media for non-volatile memories. However, most of the ferroelectric materials known suffer from high internal resistances, large bandgap, and poor carrier transportation, which hindered their further applications. The …

Fine tuned: adjusting the composition and properties of semiconducting 2D alloys

“Scientists experimentally realize 2D Si-Ge alloys with tunable electronic properties, getting us closer to a breakthrough in modern electronics Semiconducting 2D alloys could be key to overcoming the technical limitations of modern electronics. Although 2D Si-Ge alloys would have interesting …
