SunZilla A DIY SolarPowered Generator To Go

SunZilla is a portable solar generator designed to replace conventional diesel generators in remote areas or outdoor events it travels in a box and the solar panels just unfold like a flower but it's even more it's an open source framework which allows you to develop your own modules We put all the different functions like inverting from DC to AC, for example we put them in standardized boxes which can be just plugandplayed to each other All the plans are open and you know exactly what you have to do.

To make a module which fits to our system and you can even adapt the code to make it perfect to your needs It's tackling 2 problems The social problem is that there's lots of people in the world that don't have access to energy you don't have to bring a whole grid to them but you can just bring SunZilla Of course, the environmental impact is there's less use of fossil fuel the diesel generator emits noise and air pollution and SunZilla does not in the bigger picture it's about making people independent again.

From big power suppliers we want to create grids from the bottom and not from the top of course, I could go to a big company as an engineer, I would earn a lot of money but this is not what I want I want to leave my footprint a positive footprint in the world and use the time I have in my life to do something great and make the world a bit more sustainable I was always looking for a project or something where I can put my energy in.

Which will provide a benefit to the environment or to people, in general, in the world for me, it feels very selffulfilling to know that we work as a group and we are deciding on what we do and why we do it You feel connected to a bigger community of people who try really hard to work on this issue it feels like, okay, we are going in this direction and maybe we'll arrive there and could contribute something to it, too life is about learning and with such a project.

Mission Solar System Robo Arm Design Squad

Hi, I'm Deysi from ltigtDesign Squad,ltigt and I'm here with Anna, Ethan, and Arun. ANNA Our mission is to make a robotic arm using cardboard, string, and straws. DAISY NASA uses robotic arms because lots of its missions don't involve people. Also, mechanical arms are much stronger than human arms. Our robotic arm needs something flexible, something that can be pulled without breaking, like string. ANNA That works. DAISY String is good in tension. It also needs something rigid for the bones, like cardboard, which is good in compression. ARUN Our robotic arms are a lot like human arms.

They have a hand, a forearm, and an upper arm. faint whistling ARUN But people don't need a string to move their fingers because they have arm muscles to pull their tendons. ANN Sometimes things don't go the way you want them to. laughter ARUN So if you pull this string, it moves this way. DAISY That's awesome. You know, the cool thing about robotic arms is that it's a system of levers. So when you pull, the sections move around the pivots, making the end of the arm move a lot.

A baseball bat is also a lever. You put lots of force in one end, and you get lots of movement in the other. I'm trying to make it so if you pull this, it moves backwards. But it doesn't. ANNA The string keeps getting bunched up. Maybe we could use fishing line, it's more slippery. DAISY Have you tried picking something up with it I need to find something to hook it around. Okay. Yeah. laughing I got it! Let's see if these robotic arms could pick up some space rocks.

Mission Solar System Soft Landing Design Squad

Three, two, one. Hey, I'm Nate from ltigtDesign Squad.ltigt I'm here with David, Robbie, and Dylan. DYLAN Our mission is to use craft sticks, balloons, and rubber bands to design an airbag system that can safely land an egg from a threefoot drop. Because rovers are fragile, like eggs, NASA needs to find a way to help them land softly on the surface, so they won't break. For three of the rovers, NASA wrapped the whole rover system in a layer of balloons to cushion the impact and let it bounce softly across the surface.

That's exactly what we're trying to do here. Our landers have a good amount of kinetic energy as they move toward the ground. We're trying to safely dissipate that without crushing the egg. My design is to have three balloons at the top to make drag. I have two cups, each with a balloon inside. So that when it goes down, it scrunches up and it's almost like miniature airbags. DAVID My idea was more like a suspension kind of thing. It's going to be like a net underneath it. The egg's going to sink into that net.

NATE We've got a builtin suspension system, and when we step off something tall, we go boing, and we're doing the same thing to protect our own bodies as you're going to do to protect your egg. Our legs compress our hips and knees. So instead of hips, and knees and muscles doing it, you're going to use the rubber bands. So what I'm building is supposed to land on this balloon just to soften the landing for this egg. NATE For the test run, let's use a hardboiled egg. And then for the real deal, we're going to put in a raw egg.

And really see if it works. Ready Let's go to the ladder. NATE Oh, man. ROBBIE You see the crack NATE Oh, yeah. What did you see happen when it hit the ground ROBBIE Well, instead of hitting from the bottom, it hit on it side so the shock absorbers never got to do their job. NATE Holy cow. Did it bounce out DAVID Yeah. You basically built an egg trampoline. It went down, hit the ground, and then sprung the egg out because there wasn't a system to retain the egg from the top.

DAVID So I added rubber bands on the top, and I put this cup here so it would have extra protection if it bounced and, like, hit the top. ROBBIE I'm just adding extra cushioning. So when it comes down, no matter which way it lands, it's always going to be shock absorbed. NATE What's the plan for your egg DYLAN I think by putting tons and tons of balloons on, it can protect the egg better. NATE All right, everybody. This is the real test with the raw eggs. Let's do it.

Mission Solar System Invisible Force Design Squad

Hi, I'm Deysi from ltigtDesign Squad,ltigt and I'm here with Eleanor and Reed and we're having fun with gravity. Gravity is a force that is present in all things. We use the invisible force of gravity to change the direction of speeding objects all the time. NASA uses it too. When a spacecraft passes a moon or a planet, they both exert a gravitational pull on one another. NASA engineers use this gravitational pull to change the direction of a spacecraft, increase the speed, or both change the direction and increase the speed.

This is called a gravity assist. Like gravity, magnets also exert an invisible force. Our mission today is to use the invisible force of magnets to control how a ball rolls without ever touching the ball. We've got a steel marble. A magnet. A paper cup that has a notch in it. An index card. folded in half to act as our ramp, and this will be Mars. ELEANOR So let's put Mars maybe over here. So then we would have to make this path instead of going straight, to curve like that.

So we're going to have to place the magnet somewhere to alter the course of this marble. DAISY We also have a piece of rope that we'll use to keep the ball from flying off the table. REED Maybe there. ELEANOR Yeah. Can we try it Yup. ELEANOR No. The magnet didn't really move the course of our steel ball. Maybe we could move this a little closer. So we don't want the ball to get too close to the magnet. ELEANOR Oh, that was close. That moved it a little bit.

REED That was pretty close. What if we tried to do something with the magnet. The steel ball tends to get attracted towards the middle of the magnet. DAISY A little too close. We're getting there. Oh, there it goes. Wait, try it again. There you go. Good job. laughter What I notice is that when the ball goes down the ramp, it always goes in a straight line unless a different force acts against it to slow it down or change its course. That's actually Newton's First Law. Now, we're going to change the direction of a rolling ball.

Mission Solar System Down to the Core Design Squad

I'm Nate from ltigtDesign Squad,ltigt and I'm here with Dylan, David, and Arun. Our mission is to collect a sample from an asteroid. This is our asteroid. And this is what scientists call a core sample. People can't travel the planets and asteroids to pick up samples yet, so NASA sends rovers and spacecraft to do it. Those machines travel to the surface of planets and asteroids to collect the core samples. The Curiosity Mars rover has a drill on the end of a robotic arm that it uses to collect core samples.

From the surface of Mars. Studying those core samples help scientists determine what conditions were like at the beginning of our solar system five billion years ago. These machines collect core samples from the surface of potatoes. ARUN We're designing a tool to collect a core sample by driving a straw into a potato slice. We've got straws, elastics, clips, popsicle sticks, and skewers. And cups. NATE There's lots of different ways to solve the problem of getting this straw into the potato. Dylan, tell me about your core sampler. So this one it will spin into it like a drill.

I stab this down and pull it up. NATE I can see it drilling in. Oh, the straw's crumpling at the end. DYLAN That failed. NATE Crunch. DYLAN So I'm building one with a rubber band so it can pull up and shoot into the core. Also this straw is stronger than the one I used before, so it won't crumple when getting pushed into the core sampler thingy. laughs NATE It's not quite reaching. Let's take a look at what's happening here. As you were pulling it backward. Those rubber bands were just sliding along.

If the rubber band's not holding onto the straw, we can't stretch it back and store energy. But if you can make it stretch back and store energy, you can release it and punch the core right in. Yeah. Look at that, it went straight through. One thing you did with this is you added a binder clip on the end, and that did the important thing of increasing the mass of the driver on the core sampler. So it has a lot more force behind it to drive the core sampler into the potato.

It worked really well. DAVID Ow, my foot. NATE Awesome. That's working pretty nicely now that you've got that rubber band on there. NATE All right, now let's try it with a fullsize potato asteroid. Hmm. The skin is a little tough. One thing to consider might be to figure out a way to add more energy to the core sampler. So that when it's punching through, it can really get deep and get through that skin. DAVID We could use rubber bands to make the straw get pushed in by itself.

Mission Solar System Inspector Detector Design Squad

Beeping sound Hey, I'm Nate from ltigtDesign Squad,ltigt and I'm here with Maya and Nicholas. We use magnets every day. They're in speakers, they hold our refrigerator door closed, and they're also used in metal detectors. beeping sound Our mission today is to make a detector that can detect a magnetic field. I can't carry anymore. crashing sound MAYA Oh, fuzzy. NATE Yeah. They are iron filings. They stick to. NICHOLAS Magnets. NATE Magnets, exactly. Magnets have a field that they put out that can exert a force on metal objects when they're nearby.

Magnets aren't the only things that make magnetic fields. In a planet or moon, when huge amounts of fluid such as molten rock circulate, it can produce a magnetic field, which is the area where a magnet's force has an effect. NASA likes to look for magnetism because they can tell a lot about what's going on inside the planet or moon by understanding its magnetic field. So to learn more about a planet or moon's magnetic field, NASA sends out spacecraft that have devices that can detect them. The devices are called magnetometers.

Right now you are being a magnet field detector or a magnetometer because you're sensing the interaction of the two magnetic fields. MAYA I feel them pushing away. NATE Try flipping over the magnet. Whoa. NICHOLAS It's kind of funny how you can feel a force that you can't see. We're going to use cardboard, cups, string, and metal shards to make our magnetometers. I'm going to use the cardboard to make a frame, and then have the paper under it. I'm using a cup and I'm cutting out the bottom to make a window.

NICHOLAS I punched these holes so that I can put string through them and hold the detector easily. MAYA When I move the magnet, the metal moves in the cup. NICHOLAS Oh, that's cool. And you know what else is interesting Listen. rustling sounds You can hear the metal moving. If I hold it too high, you can't see as many changes, but there's still a little bit. I've hidden magnets underneath the newspaper. We've put a grid down on the paper so they can point out the exact location. And this is the surface.
