You can never be too prepared for a situation that requires light.CrazyScience shared how they built a hand-crank flashlight.
For this project, I took a small SG90 micro servo, modified it for continuous rotation, and turned it into the heart of a compact hand-crank flashlight.
You can check out the details of their build on instructables.
Kyle Lambert had worked remotely for most of his career and always dreamed of having his own backyard office. A place on the property but completely separate from the home.
Until this year, that idea seemed too unnecessary… then our baby grew into a toddler. We have a small house in Portland. We love it, and it works for us, but it became clear that it could use more space.
I looked into many options. My budget’s two most viable paths were an Autonomous.ai prefab office Pod or building an office by utilizing a shed frame. The Autonomous pods are gorgeous and come prewired with electricity. You just plug them into an outlet in your house. But I wanted proper heating and air conditioning. I had spent hot summers working with a portable AC unit blasting in the background, and it just wasn’t for me. Their base starts at $16.5k; adding $5k shipping, paying someone to assemble it (I didn’t have time to DIY), and adding a mini-split HVAC system, and we were getting closer to $30k. It was not bad, but it was more than I wanted to spend, not knowing how long we plan on staying in our house.
Deciding against an Autonomous Pod left me with the shed conversion option. I decided on using Tuff Shed for the main frame. I was able to design and configure my structure using their online designer. They also have a local showroom in town, so I walked through some models to get an idea of what I wanted.

Today, anyone with a large enough artificial intelligence model can generate millions of new material designs in minutes. Unfortunately, that hasn’t led to a huge leap in the number of new materials being used to improve the performance of products like computer chips and rockets.
One reason for the translation gap is that current models don’t reliably factor in the chemical stability of the materials they generate, and unstable materials aren’t very useful in the real world. That forces industries to allocate huge computational budgets to screening out all the unstable materials they generate, in some cases leaving behind a tiny fraction of usable options.
Now, MIT researchers have developed a framework that can be applied at the beginning of the materials generation process to vastly improve the stability rate while achieving targeted material properties. It works by ensuring every design satisfies certain key rules of chemistry relating to the electrons around the materials’ atoms before the expensive generation step begins. The researchers call their approach “crystal generator with valence-constrained design, or CrysVCD.

Sometimes meandering, sometimes turbulent, every river seems to have its own character. But the behavior and nature of river networks follow mathematical rules. In 1957, USGS scientist John Hack discovered what became known as Hack’s law: The length of any stream is proportional to its drainage area raised to the power of 0.6. ( L ~ A0.6). Earlier this year, scientists discovered that Hack’s law also holds for river deltas. Read on to learn about rivers and their mathematical bedrock from Natalie Wolchover on Quanta Magezine:
Systems that branch in this way are “transport networks”: They transport some fluid substance (water, blood, traffic) from every place to a single place (the sea, a heart, a city center). Of the various examples, rivers are especially revealing, I think, since they arise from neither biological evolution nor urban planning, but rather chaotic Earth processes. Yet they obey simple, universal laws.

Colin Leroy-Mira has just released a new Quicktake for Apple II version, and it is a quite large upgrade.
The program now supports a new camera, the Kodak DC50 Zoom, released in 1996, thirteen years after the Apple IIe. The camera’s custom cable is rather easy to make (and my serial hardware allows to skip making a custom cable altogether). All features are supported (picture download, thumbnail preview, date/name/flash/quality settings, picture deletion).
The camera is able to do 115200bps on the serial port, which makes transfers blazing-fast compared to the Quicktakes!
It has both internal storage and a PCMCIA slot. Mine came with a 6MB storage card, which is a ludicrous amount of storage, allowing for 92 low quality pictures or 36 high quality ones. My program will work with the storage card when it is inserted, and the internal memory otherwise.
