 Hello, thank you. I'm Daniel and I'm working at SUTD as a researcher at the moment. And we made a tool for death competitive swimmers, basically, for the national death games that were on the 16th of July. They had a light like this, but it had a few problems. It's one flash, so you have to be on the starting clock and wait and wait and wait and suddenly there's this flash and there's a huge delay within jumping. And the other problem was there weren't so many of these devices. So we're looking into the direction of the light in order to pass the moment. So it was kind of like a few things that weren't perfect. We started by making a cardboard prototype. Working one actually. And the final product is this one. And just because for me this whole vacuum forming experience was something new so that's why I wanted to share a little bit how this worked. And I made a little video that I want to show. Just of the process of making it. For vacuum forming it's basically just heating up the PVC sheets that are three cuts, kind of difficult to organize them because they only come in huge sheets so you need to get them cut somewhere. And with the 3D process before I made little molds for an inner shell and an outer shell. The outer shell is like 2 mm PVC. So that's what we're talking about right now. Tremendously and it's probably super toxic also. So next time I would use some different materials for this. You have to have like 3 degrees of iron. You have to take a little bit so you can get the elements out of the machine. And you need a lot of howels within the mold in order to pull in the corners of the mold. You can cut like this. Cutting and so on. In the beginning we didn't think about that too much. But it's super sturdy material so it's really tricky. And took a lot of time to figure out how to actually cut them straight. So like we first did it in a way that we did rough cutting and then put it onto the machine and basically build our own tools from the materials that we had. We made like a laser cut tool basically. And like the degrease and stuff in order to be precise also. And like drilling the holes in the first point. We started by like... This was like aluminum cut 3 mm. And we made like... We were cutting threads by hand. But in the end it turned out that it wasn't like stable enough so we made 8 pieces in total. So like then we changed the design for nuts and like red holes instead. Made like custom gappers for like standard... What's it called? Camera mount. And like diffusing the lights. So like this was like took very long actually. It's kind of been done differently. Yeah so they're like two states. It's like ties in with like a competitive timing system. And it's compatible to it. And like we made it in a way that is probably waterproof. Like we didn't like dump it into water. And you can give this around also if you have questions later. Like rubber in between and metal ring on top also to screw it tight together. The shape has to be cylindrical. Yeah. With this side it will be like this. Because you have like two situations. You have like jumping from the starting block. But you also have like the situation where you're like doing backstroke. So it's kind of... Like I thought it's really confusing if you have like a direction in there. So that's why we went for like that design. And also everyone can adjust it according to their needs. So it's like a little bit like a starting block or something for track and field. Or something where you can like put it in a position where you really like it. That's why we went for circular design. How much about the plastic? The sheets are fairly cheap. They were like I think for both PVC. Like you have to always buy full sheets. It's 120 to 40. And then you have the problem of like cutting it also for the aluminum and so on. And so that's kind of a hassle. But I think it was like 100 bucks or something, 150 or something. This wasn't so bad. And like the aluminum we bought like in a smaller sheet. And the thickness is there always 2mm? You can get different ones here. It's like two different kinds. It's like 2mm for the outer shell. And 1mm for the inner. And especially once you have it in the 3D shape. It like gets even sturdier of course. So it's like... Is the LED already a ring or is it custom? It was a ring already. So we like bought the components and then designed it according to them. Alright, thank you Danielle.
