The sun may be spotless, but that doesn’t mean it isn’t doing interesting things. A geomagnetic storm is predicted for this weekend, potentially giving those at latitudes where the Northern Lights are not common a chance to see a cosmic light show. According to SpaceWeather.com, a coronal hole, a gap in the sun’s atmosphere that […]
For serious data collection with weather sensors, a solar shield is crucial. The shield protects temperature and humidity sensors from direct sunlight, as well as rain and other inclement weather, without interfering with their operation. [Mare] managed to create an economical and effective shield for under three euros in materials. It began with a stack […]
The 3DBenchy, or Benchy for short, is a popular test model for 3D printers. Designed with overhanging curved surfaces, flat planes, holes, and other difficult geometry, it’s a great way to benchmark a printer or verify that everything is set up correctly. It comes in rather handy, but at this point has also become something […]
While it’s not exactly in the same vein as other projects around here, like restoring vintage video game systems or tricking an ESP32 to output VGA, keeping chickens can also be a rewarding hobby. They make decent pets and can also provide you with eggs. You can also keep them on a surprisingly small amount […]
What’s the first thing you think of when you see an old GPS navigation system for sale cheap at a garage sale? Our research indicates that 100% of people would wonder if it could run Doom; at least that’s what we conclude from the single data point we have, anyway. [Jason Gin] asked and answered […]
How do you know if your 3D printer bed is levelled? Oh, don’t worry – you’ll know. Without a level bed, filament won’t stick properly to the build surface and you’ll run into all sorts of other problems. Knowing how tricky it can be to get the bed just right, [Antzy] built a tool to […]
Telepresence is one of those futuristic buzzwords that’s popped up a few times over the decades; promising the ability to attend a meeting in New York City and another in Tokyo an hour later, all without having to leave the comfort of your home or office. This is the premise of Double Robotics’ Double 3, […]
