“Using multiple observatories, astronomers directly detect tellurium in two merging neutron stars. An extraordinary burst of high-energy light in the sky has pointed astronomers to a pair of metal-forging neutron stars 900 million light years from Earth. In a study …
“Build a weatherproof outdoor rover for less than $500 with a Raspberry Pi and Viam. Approaching robotics can be daunting. Many of us who have tried have ended up with empty wallets, life to catch up on, and spare parts …
“Layered lithium cobalt oxide, a key component of lithium-ion batteries, has been synthesized at temperatures as low as 300°C and durations as short as 30 minutes. Lithium ion batteries (LIB) are the most commonly used type of battery in …
“Common commercial bathroom scales allow a long battery life thanks to the use of low-consumption displays (typically LCD without backlight) which, however, in low light conditions are not easily readable. My idea was to build a load cell based scale …
