Collaborate Disseminate
Something that haunts film photographers is the prospect of a film shortage. This won’t replace film in that event, but [Applied Science] demonstrates photography using leaves. That’s right, a plant …read more Continue reading Photography Goes Leaf Green
Fruit can be a tricky thing: if you buy it ripe you’ll be racing against time to eat the pieces before they turn into a mushy mess, but if you buy the ones which are a bit before their prime it’s not always easy to tell when they’re ready to eat. Do you smell it? Squeeze it? Toss it on the counter to see if it bounces? In the end you forget about them and they go bad anyway. That’s why here at Hackaday we sustain ourselves with only collected rainwater and thermo-stabilized military rations.
But thankfully Cornell students [Christina …read more
Mars ain’t the kind of place to raise a kid. In fact, it’s cold as hell. There’s no one there to raise them if you did, or is there? Is there life on Mars? That’s the question NASA has been trying to answer for the last forty years, and with the new Mars rover, we might get closer to an answer. For this week’s Hack Chat, we’re going to be talking with the people responsible for some interesting instruments flying on the Mars 2020 rover.
Our guest for this week’s Hack Chat will be [Matteo Borri], an Italian engineer who’s …read more
The pink pigments help answer the question of why complex life took so long to emerge. Continue reading The Oldest Color Ever Discovered Is 1.1 Billion Years Old
As the world’s population continues to increase, more food will be needed for all the extra mouths to feed. Unfortunately, there’s not a whole lot of untapped available farmland. To produce extra food, crop yields need to increase. [Vignesh Ravichandran] is tackling this with the Farmcorder – a device for detecting crop nutrition levels.
The device centers around using spectroscopy to measure the chlorophyll content of leaves. This information can then be used to make educated decisions on the fertilizer required to maximize plant yield. In the past, this has been achieved with expensive bespoke devices, or, at the other …read more
