Diy Solar Panel Backpack

How Do You Make a Solar Backpack Design Squad

Hi, I'm Deysi from Design Squad, and we got lots of really cool ideas for our Build it Better challenge where we ask you to help improve the design of things you use every day. Aaralyn06 took the challenge to design school supplies that work better and sent in a design for a solar powered lighted backpack. I'm excited to make a prototype of this idea. A prototype is a simple model that lets you test out your ideas. Prototypes help you understand the strengths and weaknesses of your design and how your design can be improved before you build it.

This is a solar panel, and this is how it works. A solar panel uses solar cells. A solar cell uses sunlight to make electricity. Electricity is the flow of electrons. In a solar cell, sunlight makes electrons move. A solar cell has two layers. The first layer has lots of electrons that are easy to move. The second layer has fewer electrons so it can easily take on more electrons. When light hits an electron in the first layer, it causes the electron to jump to the second layer. The sunlight starts this flow of electrons, which is electricity.

Okay, let's get started. So I have my backpack and two different kinds of solar powered lights. See how these work The rope lights are connected to the solar panel, and it turns on when the solar panel is in darkness, like this. grunting Make sure you get a grownup's permission before you cut up a backpack. We want to keep the solar panel on the outside so that the Sun can charge it during the daytime. I have another set of lights that I'm going to use for the inside of my backpack.

So that we can catch those dark corners and light them up. Ooh, look at that! The solar panel got dark and it lit up the lights. Okay, let's try this out now. grunts Oh, I'm noticing something right away. It's actually really heavy. I think that second set of lights added a lot of weight to it. But that's the good thing about prototypes. Prototypes help you understand the strengths and weaknesses of your design, and the weakness of my design is that the lights are making it too heavy.

So let's redesign. I am actually going to remove the lights from the inside. Okay, let's remove the lights. Now we're ready. Oh, much lighter now. Now it's time to test this backpack out in the dark. Woo! This actually works! The backpack is lit up. Awesome idea, Aaralyn06. Now people will be able to see me in the dark and I'll be able to see all the things inside my backpack. Send in your photos of your designs to the Design Squad website and see what other designs kids come up with.

Solar Charging Handbag

Welcome to the summer of solar! Why not soak up some free power from the sun You can build a solar charger for your phone and other gadgets, and then attach it to any handbag or backpack! Practical enough for every day, and really handy for camping or trips to the beach. Use Adafruit's solar lipoly charger kit to charge up a beefy battery, then hook up the output to an assembled Minty Boost, our popular pocket gadget charger. When you're out in the sun or as long as your bag is, the battery charges up. You.

Can simultaneously charge your phone when the sun is bright, and the battery will keep supplying juice long after the sun goes down. Assemble your kits with flatness in mind bend all your tall components over before soldering. Pack everything carefully into an Altoids tin after making cutouts for the plugs with tin snips. Replace the plug on the solar panel with a 2.1mm barrel jack I just cut the alligator clips off of this adapter. Alligator clip save me for another project! Velcro tape comes in handy for affixing the solar panel to any handbag or backpack. We.

How to Install Solar Panels Battery Banks for Solar Energy

Now we come to our battery bank for our Solar system. This one is made up of six volt cells combined in different ways to get the voltage we need for our individual inverters. We're going to be using the big Zantrax 1,000 watt this time, so we'll need two six volt cells, in series, to come up with that twelve volts. If you take your battery and connect a positive to a negative terminal that leaves you with a positive and negative terminal and you can get your twelve volts here. If you connect four batteries in series, positive to negative,.

You come up with twentyfour volts. And if you needed a fortyeight volt system, which is not uncommon, you'd simply expand and use more batteries. But for a twelve volt system we'll just use two. And, they're really the most dangerous part of the system. If you look down inside there, you can see a liquid and that liquid is sulfuric acid and will really seriously burn you and that's why we have a base here, Baking Soda, and if you get that acid in your eyes or in your clothing you can neutralize it with this. So, very.

Important to have this for safety. We can get a look at some of that acid here with the hydrometer, this is what you measure the actual specific gravity of the acid inside. And you can see we have several of these disks floating. We have about three disks floating with one at the bottom. So we know that this two batteries, or at least this battery, is about seventyfive percent charged. So, we're going to be very careful with that acid and stick this back here in our little cup. It's also important to note that the gases that.

How to Make Potassium Nitrate at Home

Greetings fellow nerds. In a previous tutorial I made potassium nitrate using ammonium nitrate from instant cold packs and potassium hydroxide. Since the latter chemical isn't easy to obtain I will revisit potassium nitrate production but using potassium chloride instead which is much easier to get. The method has the added advantage that it doesn't produce toxic ammonia gas. However it is less efficient than the original method and produces lower quality product. Anyway let's get started. Measure out 40 grams of the ammonium nitrate. Like in our previous tutorial, we got it from instant cold packs that clearly say ammonium nitrate as the main ingredient.

Do not use urea. Now add 100mL of water and stir until completely dissolved. The insoluble material is an anticaking agent. Filter the mixture directly into 37 grams of potassium chloride. Potassium chloride is very easily obtained as a sodium free salt alternative for those seeking to lower their sodium intake. This is very popular now and almost all grocery stores stock such salt along side regular table salt. The brand might be different but if you check around the labels it should say somewhere that it's composed of potassium chloride.

Or that it has all potassium and no sodium. Here we are. Now once the mixture is filtered through you'll need to gently heat the mixture with stirring until all the potassium chloride is dissolved. It might still be cloudy due to anticaking agents in the potassium chloride but this will be fine. Just focus on getting all the salt dissolved. Now it's all dissolved. Just take it out and put it into the freezer to cool. Since I'm impatient I'm going to use an ice bath and allow you to see the potassium nitrate crystallize out.

What's happening in terms of chemistry is that we're exchanging the ions in the potassium chloride and the ammonium nitrate to create potassium nitrate and ammonium chloride. Potassium nitrate has low solubility at colder temperatures so it crystallizes out. The ammonium chloride stays in solution so we can separate it from the potassium nitrate by filtration. Now we had to heat the solution in the beginning to get all the ions dissolved so that this exchange can proceed as far as it can. Sodium nitrate cannot be made this way using sodium chloride or table salt.

Because sodium nitrate is too soluble to be efficiently separated by this process. Please refer to my previous tutorial if you really want it. Ok the solution is cold enough. Now you can see these large crystals of potassium nitrate. Just pour off the excess liquid and filter to squeeze out every drop. The let the crystals dry. Now you have crude potassium nitrate. To test it, once again crush the crystals and mix them with about half as much sugar and set the mixture on fire. So that's how you make potassium nitrate at home.

Yellowstone Park Recycles Vehicle Batteries for Solar Power

MotorWeek is made possible by Rock Auto, Tire Rack, and DieHard. While hybrid and allelectric vehicles are great for the environment, giving off little or no harmful emissions, the long term aspects are a little more troubling. What do you do with and how do you properly dispose of those large battery packs and the hazardous materials contained in them Well, leave it to the National Park Service to find a green solution. Partnering with Toyota, Yellowstone National Park's Lamar Buffalo Ranch has given a whole new meaning to usedcar shopping.

Recycling battery packs from older generation Toyota Camry Hybrids, the ranch uses them to store solar power. Despite being past their automotive prime, these used nickelmetal hydride batteries can still hold a substantial charge. Two hundred eight battery packs are used to store enough solar energy to power the ranch's fivebuilding campus around the clock. So to put it this way, a year's worth of sunlight provides a year's worth of electricity. And, with automotive battery technology improving, used lithiumion battery packs will soon become available with even higher capacity. Imaginative.
