Most people can tell you the various uses of the umbrella — it keeps the rain off, pokes sleeping train passengers awake, and can be used as an improvised defensive weapon when tension in the hot dog line reaches boiling point. A true Englishman would never deign to employ their brolly so imprudently, of course, but they might just give it an upgrade by packing in a full weather station.
The build uses the Particle Photon as the brains of the operation, interfacing it with several sensors. There’s a DHT11 to handle temperature and humidity measurement, an Adafruit barometric pressure sensor, along with a custom-built anemometer using a brushed motor with 3D printed wind cups. Finally, a breadboard is turned into a rain detector, based on the same principles as those used in automotive applications.
The Particle Photon uses WiFi to tether to a smartphone, deliver the collected data to the cloud via Adafruit IO. This enables the data to be collated and processed further on a PC. Yes, it’s 2018, and they have the internet on umbrellas now.
Yes! Someone made the Kingman umbrella and yes it can shoot and yes it has a display on the inside. [James Hobson] just put up a video on YouTube for this excellent project detailing the process that went into creating this live working prop and it is amazing.
The build starts with finding a rugged umbrella and was tested by standing on it as well as decimating a few household objects. Compress CO2 cartridges provide the fuel for propelling blow darts as well as other non-lethal forms of ammunition. The coolest part of the project is the screen inside the portable that allows you to see-through the dome. This is accomplished by a combination of a small camera and a portable mini projector. Simple yet awesome.
The camera is mounted near the muzzle whereas the projector is sliced-up and integrated into the grip. The handle in question is itself 3D printed and includes a custom trigger into the design. Check out the video for a demonstration of the project.
Movie props have a special place in every maker’s heart and this project is an excellent example of imagination meeting ingenuity. After seeing this video, security agencies are going to be giving umbrella owners some suspicious looks though creating own of your own could be a very rewarding experience. If you are looking for a more obvious prop, then check out the PiPBoy Terminal from Fallout which is sure to get everyone’s attention. Continue reading “Hacker Maketh Kingsman Umbrella”→
Mount an umbrella to a drone and there you go, you have a flying umbrella. When [Alan Kwan] tried to do just that he found it wasn’t quite so simple. The result, once he’d worked it out though, is haunting. You get an uneasy feeling like you’re underwater watching jellyfish floating around you.
A grad student in MIT’s ACT (Art, Culture and Technology) program, [Alan’s] idea was to produce a synesthesia-like result in the viewer by having an inanimate object, an umbrella, appear as an animate object, a floating jellyfish. He first tried simply attaching the umbrella to an off-the-shelf drone. Since electronics occupy the center of the drone, the umbrella had to be mounted off-center. But he discovered that drones want most of their mass in the center and so that didn’t work. With the help of a classmate and input from peers and faculty he made a new drone with carbon fiber and metal parts that allowed him to mount the umbrella in the center. To further help with stability, the batteries were attached to the very bottom of the umbrella’s pole.
In addition to just making them fly, [Alan] also wanted the umbrella to gently undulate like a jellyfish, slowly opening and closing a little. He tried mounting servo motors inside the umbrella for the task. These turned out to be too heavy, but also unnecessary. Once flying outside at just the right propeller speed, the umbrellas undulated on their own. Watch them doing this in the video below accompanied by haunting music that makes you feel you’re watching a scene from Blade Runner.
[Rulof] never ceases to impress us with what he comes up with and how he hacks it together. Seriously, how did he even know that the obscure umbrella part he used in this project existed, let alone thought of it when the time came to make a magnet mount? His hack this time is a real world, tabletop race track made for his little brother, and by his account, his brother is going crazy for it.
His race track is on a rotating table and consists of the following collection of parts: a motor, bicycle wheel, casters from a travel bag, rubber bands (where did he get such large ones?), toy car and steering wheel from his brother, skateboard wheels, the aforementioned umbrella part and hard drive magnets. In the video below we like how he paints the track surface by holding his paint brush fixed in place and letting the track rotate under it.
From the video you can see the race track has got [Rulof] hooked. Hopefully he lets his brother have ample turns too, but we’re not too sure. Some additions we can imagine would be robotics for the obstacles, lighting, sounds and a few simulated explosion effects (puffs of flour?).
This project takes an umbrella stand and gives it the ability to let you know if you need to take an umbrella when you leave the house. The image above is a concept drawing, but a first prototype was built and seems to work quite well. See for yourself in the video after the break.
The project was put together by openPicus. They sell a prototyping module called the Flyport which provides a WiFi connection to your projects. This board connects to a set of LEDs which are used to illuminate the translucent plastic umbrella stand. But you might not notice the color change if the LEDs were always on. Also designed into the system is a PIR motion sensor. When you walk toward the door to leave for the day it switches on the appropriate color — green for clear, blue for raining, and red for storming — catching your attention in time to grab an umbrella as you pass by.
Anemometers measure wind speed by capturing it with egg-shaped sails (in fact, we’ve seen them built from plastic Easter eggs before). The umbrellas have a much larger area and will capture more wind. Still it’s a big jump from measuring wind speed to generating energy. That’s why he’s not trying to generate electricity, but instead using the mechanical force directly. He took a page from one of last year’s projects and used the dual umbrella setup to power a music box, thereby reinventing the wind chime. The triple-umbrella unit seen above serves as a bubble machine, driving a series of plastic rings through a soapy solution and letting the wind do the rest. We’ve embedded his demo video after the break.
In a decision we completely agree with, these industrious young women decided that playing in the rain would only be more fun if it included an interactive light show. They wanted the rain itself to cause LEDs in their umbrella to light up. To achieve this, they put piezo sensors on each of the 8 panels of the umbrella. When that panel gets hit, its LEDs light up. You can see in the video after the break that it was quite effective.
Their next step should be to somehow increase the resolution to be similar to this one, while maintaining interactivity with the rain. How would you sense rain drops with more definition though?
