“Create a smart door lock that utilises BLE for local unlocking and a mobile app integrated with Blues Notecards for remote unlocking. Building a smart door lock has been on my to-do list for the longest time. Many DIY smart …
“Artificial plant with environmental monitoring India faces significant challenges related to air pollution, with several cities consistently ranking among the most polluted in the world. Among these, a few stand out as particularly affected by high levels of air pollutants …
“A little solar-powered E-Ink weather station that fits in a window frame. A new project is up and running! During the last couple of months, I have been working on a power-efficient and small form factor weather station. I designed …
“By analysing images made of coloured dots created by quantum simulators, ETH researchers have studied a special kind of magnetism. In the future this method could also be used to solve other physics puzzles, for instance in superconductivity. Up close …
“Last post I described a subcircuit that would take an audio signal from maybe 50K to below audible frequencies and turn it into a square wave—useful for turning audio into a clock signal for an MPU. It worked, but …
“The intertwining of a human’s senses is a beautiful art. Film, cinema, and theater mix sight and sound in ways that affect how we feel emotionally in a significant way. The music we hear during a scene drastically affects …
“Perception of time is really an amazing and fascinating topic. Often we see analog clocks and get a feeling “Are we stuck in a loop going round and round”?, though in reality time is flowing continuously. Inspired from this, I …
“Ultrafast laser spectroscopy allows the ascertainment of dynamics over extremely short time scales, making it a very useful tool in many scientific and industrial applications. A major disadvantage is the considerable measuring time this technique usually requires, which often leads …
“Real time control of a many solenoids. As I designed an self-designed PCB(MCP23017 IO Expander for 16 solenoids on 1 board) to control a large number of solenoids and built an enclosure to house 100(10x10) solenoids. Then I …
“”Soft robots,” medical devices and implants, and next-generation drug delivery methods could soon be guided with magnetism — thanks to a metal-free magnetic gel developed by researchers at the University of Michigan and the Max Planck Institute for Intelligent Systems in …
