Every day, observations and orbit solutions for Near-Earth Asteroids (NEAs) are received from the Minor Planet Center (MPC) in Cambridge, Massachusetts. Once classified as an NEA, the asteroid is thereafter given automatic orbit updates within our Sentry system. A new orbit solution for an NEA is computed whenever new optical or radar observations for that object become available. Some high-priority objects are observed daily, while other objects go unobserved for days or weeks, even though they may still be bright enough to be seen. Optical observations cease when an object recedes from the Earth (becoming too faint to be seen even with moderate-size telescopes), or when the object moves into the daytime sky. Similarly, radar observations are possible only when the object is near enough to the Earth for the echo of a radar bounce to be detected. Once all the observations for an object have been collected, an orbit determination process is used to find the orbit that best fits all the observations.
It is important to understand that an object’s orbit is never known perfectly. Although the nominal orbit solution fits the observations best, slightly different orbits may still fit the observations to within their expected accuracies. There is in fact a whole set of orbits around the nominal that will fit the observations acceptably well: these all lie within what we call the uncertainty region about the nominal orbit. The ‘true’ orbit is expected to lie somewhere within this region. As new observations of the object are made, the uncertainty region becomes more tightly constrained and the range of possible values for the orbital elements narrows. As a result, objects that have been observed for decades will have highly constrained, well-known orbits, while newly discovered objects tracked for only a few days or weeks, will have relatively poorly constrained, uncertain orbits.
Once the nominal orbit and its associated uncertainty region have been determined, the object’s motion is numerically propagated forward in time for at least 100 years in order to determine its close approaches to the Earth. These nominal orbit close approach predictions are tabulated in our Earth Close Approach Tables along with other uncertainty-related information such as the minimum possible close approach distance, and the impact probability. The uncertainty-related parameters in the close approach tables are computed by propagating the uncertainty region from the epoch to the respective close approach times via so-called linearized techniques. Since these techniques lose accuracy when the uncertainties become large, we include only reasonably certain predictions in our Close Approach Tables. As a result, close approaches may be tabulated decades into the future for objects with well-known orbits, but only a few months or years into the future for objects with poorly known orbits. On the other hand, Sentry assesses the long-term possibilities of an Earth impact for all objects whose orbits can bring them close to the Earth, even those with poorly known orbits. To perform this risk analysis Sentry uses more sophisticated nonlinear methods.
I don't know if there's an API or feeds or what, I haven't looked that closely into it yet.

This project aims at building an ultra low power adapter (< 1uA quiescent current) that you can bring onto modern smart energy meters to read the energy usage.
The optical interface consists of an IR photodiode to read data from the smart energy meter, and an IR emitter to send data to the smart energy meter. The infrared reader has an automatic calibration to ambient light conditions to be more resilient against ambient infrared light.
4 wires: VCC, GND, RX and TX. RX is for receiving UART data from a microcontroller, TX is for sending the optical data to a microcontroller. So usually you want to connect TX to the UART input of your microcontroller to get your readings from the smart meter. RX can be left unconnected if not used. The supply voltage may be between 1.8V and 5.5V.

This website is dedicated to covering tropical activity in the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. The Eyewall was founded in June 2023 by Matt Lanza and Eric Berger, who work together on the Houston-based forecasting site Space City Weather.
Our purpose is to extend our no-hype approach to forecasting weather to hurricanes across the entire Atlantic basin so that residents and business owners at risk for storms can have access to quality forecasts and make informed decisions about protecting their families, property, and businesses.
SniffleToTAK is a proxy tool that bridges the gap between the Sniffle Bluetooth 5 long range extended sniffing and the TAK (Team Awareness Kit) system. This tool allows users to utilize a Sniffle compatible dongle to detect Bluetooth 5 long range extended packets and relay them to TAK servers or multicast them on a network for ATAK (Android Team Awareness Kit) devices.
Basically, some drones use long-range Bluetooth 5 for beaconing and telemetry. This means that if you can pick up and decode that traffic you can track those drones.
Requires Sniffle and a compatible Bluetooth interface as its inputs. Outputs to an ATAK device for tracking.
The Polaric Server is mainly a web based service to present live tracking information (APRS, AIS, etc) on maps and where the information is updated in realtime. It is originally targeted for use by radio amateurs in voluntary search and rescue service in Norway. It consists of a web application and a server program (APRS daemon). It runs on e.g. aprs.no as a online service on the internet, but we could also bring it with us out in the field in a portable computer, possibly with its own LAN, APRS modems and radios. A goal is that it should be able to work without always being online with a good connection to the internet.

EFF’s Street-Level Surveillance project shines a light on the surveillance technologies that law enforcement agencies routinely deploy in our communities. These resources are designed for advocacy organizations, journalists, defense attorneys, policymakers, and members of the public who often are not getting the straight story from police representatives or the vendors marketing this equipment.
Whether it’s phone-based location tracking, ubiquitous video recording, biometric data collection, or police access to people’s smart devices, law enforcement agencies follow closely behind their counterparts in the military and intelligence services in acquiring privacy-invasive technologies and getting access to consumer data. Just as analog surveillance historically has been used as a tool for oppression, we must understand the threat posed by emerging technologies to successfully defend civil liberties and civil rights in the digital age.
COVID-19 continues to kill and injure many people daily. With the collapse in case data reporting it has become difficult to show that high-risk events such as large meetings, performances, and other events result in quantifiable harms.
This web app allows you to create a sharable event link for attendees to report their symptoms and test status anonymously. The public event page will then display how many attendees have become sick or tested positive in an easy-to-digest form along with expected impact (e.g. how many might be expected to get Long COVID). These statistics can be used to help you advocate for increased COVID-19 mitigations in your workplace or other groups.
It may be difficult to get people to disclose their status publicly with their name attached to colleagues (it's embarassing and everyone is trying to ignore COVID), but it is much easier for an activist to drop a link and aggregate anonymous statistics since there is less chance of blowback for such disclosures for the individuals and they'll feel like they're contributing to public health and workplace safety.
For the organizer or activist, information is power. Statistics are able to show the real harms that are occuring and can be used to advocate for safe events and workplaces. It also gives your fellow attendees a way to help each other in a clear and structured way that the Federal government should be providing, but isn't.

WAEL is a simple self-hosted weight and exercise log - track your weight and exercise over time with basic metrics and a handy little chart. It can be self-hosted.
NOTE - the Docker setup for this project has been specifically tailored to work on a Raspberry PI, and as such expects to run on arm64 / aarch64 processor architecture. If you want to run on your own rpi, make sure you are running a 64 bit version of your operating system because prisma (the ORM used in this project) requires it.
I guess the Dockerfile can be dissected to figure out how to run it properly?
