12V DC Motor Controlled By Adafruit TB6612 Motor Driver

“This Arduino code controls a 12V DC motor (linear actuator) using an Adafruit TB6612 1.2A DC Motor Driver and external 12V power supply. For this project, I wanted to control a motor, specifically a linear actuator (with linear motion …

A bug fix in the 8086 microprocessor, revealed in the die’s silicon

“The 8086 microprocessor was a groundbreaking processor introduced by Intel in 1978. It led to the x86 architecture that still dominates desktop and server computing. While reverse-engineering the 8086 from die photos, a particular circuit caught my eye because its …

A crystal shape conundrum is finally solved

“Rice theorists’ method can predict shapes of crystals that lack symmetry A crystal’s shape is determined by its inherent chemistry, a characteristic that ultimately determines its final form from the most basic of details. But sometimes the lack of …

Accelerating plastic degradation in the environment: Bayreuth study researches heat resistance of enzymes

“Numerous plastics are principally biodegradable, but are only degraded very slowly in the open air, wastewater, or composting plants. Known enzymes with the ability to degrade plastics could solve this problem. To do so, however, they must be able to …

Amateur Scientists Have Helped Astronomers Identify Nearly a Quarter-Million Galaxies

“Astronomers on a historically ambitious and massive galaxy-mapping mission have activated more than 10,000 amateur scientists in 85 countries to help in their quest. Now they hope to significantly scale up their volunteer force for a unique project that …
