Okay, so now let's figure out some kind of a way that we can secure this solar cell and possibly and close this battery at the same time. So let's create a holder for this solar cell if I go to assemble a new component, and let's call it solar cell holder and hit OK. Let's go to sketch create sketch, choose a plane. And let's again make this circular. Let's make it the same diameter as the piece down below 3.25 inches in diameter. And let's give it a certain thickness create extrude. Let's make the thickness, let's say three as this time, three, eight hit okay?

Because we're gonna want to activate the assembly and I want to remove or hide the origin so that we can see a little bit better here. I'm going to want to put this solar cell into this piece here. So let's activate our solar cell holder again. And let's go on to this top surface sketch, create sketch. And let's create a rectangle, we can Just create a rectangle, we know that the size of the solar cell is 50 millimeters by 50 millimeters. So I could do say 50.5 millimeter and the same here.

Stop sketch and this time we want to cut extrude. I know that the solar cell is three millimeters thick, so I could go we can go ahead and go with three. Let's see if that worked. Yes, it did. So now I have some kind of an enclosure or a holder of types. For this solar cell, I activate the assembly.

Let's just put this in here and see what it looks like. So we go to assemble joint, choose there and there. And I want this to be a rigid joint. So I want it to be held still. And looks okay, let's hit OK. So I have my solar cell in here.

And if I take this solar cell holder, I right click go to opacity control, and I just want to be able to see through it I clicked on 20. You can see the thickness of the solar cell relative the thickness of the whole piece. Just for better visualization here. let's right click the solar cell and give it a different color. So the solar cell might be a plastic and we could do say that and so we drag the plastic onto that, and hit OK. Let's take the solar cell and increase the opacity again. So there we go.

So now we have some distinction between those two pieces. Now, this is going to be our top. So I want to bring the sides down of this piece to enclose our battery. So let's activate the solar cell holder. Click the bottom of it because we're going to draw on that face. Go to create sketch.

Some of those lines behind are a bit confusing. I'm going to right click and choose either isolate so that I'm just working with the solar cell folder. And let's choose. We're gonna make one circle to the outside and another circle to the inside. And let's dimension it at say exactly three stop sketch. Now let's extrude that to make a type of top.

And I'm not sure how far to extrude that let's just hit OK for now, and right click on isolate and see what we have. That's the piece that's grounded. We would have something like this. And let's change the opacity of the solar cell holder. So we can see through it a little bit. And it looks like we didn't need to be quite as high if we're just putting the battery in here.

And so let's go back and activate the solar cell folder, you can see that the timeline just shows the operations from the solar cell holder. I can right click the extrude that we just did, and let's decrease the length on that if we just put it to one. What does that look like? One inch that looks okay for now. And activates the entire thing. I don't think we need quite this thickness on this top piece here.

Actually, that's Okay, let's just stick with that. So let's put our pieces together and see what we have so far. And actually, let's go ahead and constrain some of these pieces. So it's just easier to visualize if I go to assemble a joint. And let's choose the center of this piece. Well, let's first of all let's choose the center of our cover.

And we're going to do a cylindrical joint. And I'm trying to choose the center of this piece. The animation looks like what we want. And let's hit OK. So now if I move this, it just moves up and down. Let's do the same with this piece.

So if I go to assemble joints, choose the center there and choose the center there. Let's see if those match up and hit OK. That's a cylindrical giant as well. Looks like that worked as we planned it. So now I'm gonna have to figure out a way to attach this top piece to my battery holder piece. And then I have my led here and potential light color. I don't know what that's gonna look like yet, but I know that my LED and the light cover are going to I know my led needs to be below this surface.

Let's actually take the LED right now and assemble joint. See if we can find a center point on this LED and a center point on that piece and it's a cylindrical type joint. Let's hit okay. So now my LED is right in the center which is probably where it's going to be. So I could have my led have the wires stick through this piece to wire up to the battery. And then I could have my solar cell wires come down through this top piece and also go to the battery or go to a terminal in between The battery.

So let's talk about materials. And what we've created so far here we have the solar cell, which is going to be premade. Or we're just buying that as a part, we can buy a rechargeable battery, and I should be able to buy an LED this top solar cell holder piece. And this piece right here, which holds the battery, those are pieces that we're going to have to custom make. Now, speaking of materials here, we need to keep our design constraints in mind. So we know that this is going to be outside we're going to need resistance to corrosion or water resistance so that you know if we choose, for example, just a regular plain carbon steel to make these I would say that not only would it be, you know, probably two Heavy it could work but it's generally probably too heavy but it would rust if this is sitting outside all the time.

So we know a design constraint is we need corrosion resistance. I would say that we want to we want a lot of these parts to be somewhat lightweight. I don't want an extremely heavy yard light yard solar light. So we know a few things so far. And looking at our more comprehensive material list are these are categories of materials for the top solar cell folder. Again, we want corrosion resistance we want lightweight, so we're possibly talking composites.

Ceramics are going to be typically for you know, high temperature applications. We probably won't need a ceramic for you know, either the battery holder The top solar cell holder, but we could be talking about a corrosion resistant metal, probably too heavy. We could definitely be talking about plastics, maybe a composite. But if we can stick composites are a little bit more difficult to manufacture. So we commonly stick with, you know, metals and plastics to make a lot of parts. Of course, we're not going to be using for those top pieces, fabric glass, rubber, or wood for those and so we're basically looking at most likely a metal or a plastic.

Well, we know that we're not going to be able to find pre made parts for the top solar cell holder and the battery holder. We're gonna have to go with a custom part. We asked what material we just looked at the more comprehensive material category list, and we're definitely thinking that metal or plastic is a is a good potential option. So if we look at plastic, one option definitely would be to 3d print. So I'll start with liquid molten material and 3d print, that's going to give us a lot of freedom on being able to design these very custom parts like this. If we were to start with a plastic and custom turn those pieces because they're cylindrical pieces, so we could start with a plastic, we could use a solid start with a solid rod and then we could turn at least a portion of those those pieces.

We can turn and mill the plastic in order to achieve the top two. But a better more efficient option might be to 3d print. That is what I would suggest that we can do we can 3d print for a should be able to 3d print these two pieces for a pretty good price. Let's go ahead and figure out what we should do for this light cover here. So now for this light cover, we know that it needs to be transparent back to this diagram here. First of all, we would ask Can we get a transparent part pre made for us, we might be able to do it by get it cheaper in that way.

So we would have to find some kind of a glass globe, either online or from a local store. If we don't pre make the part, then we would have to come up with some kind of a custom material that is clear. We probably don't want to make a custom glass part as we talked about to be able to hold up to wear outside we really might want to go with a clear plastic. So we talked about one of the clear plastics is acrylic and in that case, it's going to be a little bit more durable than using an actual glass so it might hold up to more wear and tear outside and be less resistant to breaking if we have a clear plastic instead of an actual glass which could Break or fracture on us we know to clear plastic would work and let's go ahead and see if we could make a clear acrylic custom piece.

Now a very good place to get stock parts would be mcmaster.com especially in the United States if I'm looking for you can actually go to just raw materials over on the left here and you can see a lot of different raw materials. So these are a lot of the raw materials that we you know we have talked about, so we're looking for our clear acrylic or our plastic so let's choose plastics. We are going to want to we're going to want a tube of plastic and now we're looking for acrylic. See if we can find a credit Like the list over here, looks like it does exist Acrylic plastic. Let's choose that. And we have clear cast acrylic tube.

So this could definitely work. It's a just a straight tube. So it's not going to be too fancy, but I think we can definitely make this work. So this od right here is the outer diameter. If we go back to fusion 360 we need to figure out an outer diameter that the two will be. If I go to inspect, measure and check the outer diameter here again, we made that 3.25.

Let's see if we can find 3.3 and a quarter. And these are different inner diameters. So there's three of them at three and a quarter here. I could just choose one of them. Let's go with the bottom one, we'll click on it. product detail.

A lot of the times McMaster has CAD models but in this case it doesn't have a CAD model for this, but I know that the outer diameter is three and one quarter, the inner diameter is three inches. And we should be able to cut it to length. So you know, we could choose one start with one foot in length by this part and just cut it to length or we can have the machine shop do it for us, of course, a machine shop which we will talk about. So let's go ahead and just delete this piece Actually, we could just modify this piece because it's very close to what we're looking for. So if I choose that and highlights over in the tree here, let's activate that part, we should be able to just modify this sketch in order to get the part that we're looking for.

If I edit sketch so instead of three and 2.8, we said that the outside was 3.25. And the inside was three. And if I stop sketch this should now be a clear cast acrylic tube exactly as we can order here three and a quarter by three. And in terms of a length, we can cut it to length and figure out what what length we would need. Currently, if I edit this feature, currently, the length on it is 3.199. Let's make it More of a simple number, more of a standard number that is and hit OK.

So now we have a three inch clear acrylic tube. let's right click and set the material if I go to plastic I have transparent plastics here and it looks like clear acrylic does exist. Let's drag it on to that part and hit OK. Let's activate our assembly and see what we have so far. So now I have this clear tube My battery holders should be grounded. Or looks like I lost my ground here for some reason I'm not sure how. So now we can see that this tube is going to have to meet up with our battery holder, but it shouldn't close the light.

And then we have our top here, which will enclose the battery and we have a good start here.
