“Circuit design for using multiple VL53L0X breakout boards. In this design, we have a sensor facing forward, left, right, and up. The application of this board was towards obstacle avoidance for WiFi drones. Supplies: - VL53L0X Sensor x4 - Right angle headers …
“This robot is completely guided everywhere by whistle, much like the “Golden Sonic Toy” made in 1957. When switched on, the robot moves in the direction indicated by the illuminated arrow on the front drive wheel mechanism. When the whistle …
“Yale physicists have developed an error-correcting cat — a new device that combines the Schrödinger’s cat concept of superposition (a physical system existing in two states at once) with the ability to fix some of the trickiest errors in a …
“Mimicking the structure of the kidney, a team of scientists from Lawrence Livermore National Laboratory (LLNL) and the University of Illinois at Chicago (UIC) have created a three-dimensional nanometer (nm)-thin membrane that breaks the permeance-selectivity trade-off of artificial membranes …
“Some time ago I was asked to solve the following problem: a small choir plays a number of four fixed microphones. The audio signals from these four microphones had to be amplified, mixed and the resulting signal had to be …
“The 8 Channel Driver Arduino UNO Shield is designed to enable users to switch inductive loads for up to 800mA each channel and up to 24V DC with no heat-sink needed. It is ideal for such applications as driving 2x …
“NUS physicists have demonstrated the control of magnetism in a magnetic semiconductor via electrical means, paving the way for novel spintronic devices. Semiconductors are the heart of information-processing technologies. In the form of a transistor, semiconductors act as a switch …
“Researchers at Karlsruhe Institute of Technology (KIT) and Jilin University in Changchun/China investigated a highly promising anode material for future high-performance batteries – lithium lanthanum titanate with a perovskite crystal structure (LLTO). As the team reported in the Nature Communications …
“Do you often forget to water your indoor plants? Or perhaps you give them too much attention and over water them? If you do, then you should make yourself a battery-powered soil moisture monitoring stick. This monitor uses a capacitive …
“How to make the wearable activity tracking watch? This is a wearable gadget designed to vibrate when it detects stagnation. Do you spend most of your time on the computer like me? Are you sitting for hours without realizing it …
