 So we're presenting on SCUBC. So what exactly is SCUBC? The Singapore Alamo's Underwater Vehicle Challenge is an effort by the IEEE Oceanic Engineering Society Singapore chapter, Expositions to Challenges to UD Design, which we will later learn is not exactly as easy as anyone thinks. So the competitors are tasked with building their own UD from scratch. So quick content overview, just heads up, we'll all be covering electronics for programming. So on mechanical design, our POV, which is not here with us today, because it's under development, we're redeveloping it, Sandwich was designed to be modular, easy to maintain, amenable and operable. So first, modularity. So the design was based on underwater camera rigs found on constructables. So these essentially consist only three products. And had a balance between how flexible it was for future development, as well as the number of points of failure it introduced. So this was our original enclosure. So as you can see, it's matching from a single piece of acrylic and sealed with four bottle joints. My partner is off getting it right now. So essentially, only four are exposed to union for mounting alternate caps in the sense that we can just re-manufacture a different part with alternate caps. As you can see here, this was a three printed part because we wanted to reduce the weight. So quite a few of them here are clearly much more. So yes, I'll pass that around. The USB cable is like, yes, the USB cable is an implementation for programming. So yes, first design failure. As we see here, it's holding a silicone. Cable lads can be installed in three schematic accolades. So these are the issues. Because heavy pack was space-infusion, and it was inherently un-flexible. Easy access because we only needed, we only turned four nuts to release them at any one point. And they also doubled as well, as you'll see later. So yes, this was our USB. So these are budgie cords. Why budgie cords? They are flexible, and they're very easy to mount on this mount in the sense that you just hook onto the threaded rods. So it was quite unorthodox, and introduced some problems, such as the center where it may shift. But we found that force purposes and service are good. So yes, drop-backs are, it would sell again as subject to wear. But the fast mounting and somewhat short resistance of multiple times we slanted a wall on this thing were decent trade-offs. Now, easy to maintain. So there's no USB cable. So I think every run, you have to break the seal. But now we fix that with the new tether that we attached. So actually the subcon cable, which we will not show because it's been taken off, these cables are actually quite expensive. Then the budgie cords will be able to release in seconds as I just mentioned. And also the rods can be unfastened from either side in the sense that 16 knots, sorry, 8 knots, you can adjust them to them. So the design concept behind this was that we had two enclosures, one for the battery, one for the computer. So reduced hassle when you change batteries with the program. So these were later proved catastrophic. Finally, a 9-point-volt operable essentially was only 16 kilos and can be assembled in one person although it might give them a hassle. So how long Daniel will talk about something issues we encounter during this? I don't know. That would be a lot. We couldn't walk here on one of our people. Okay, so if you can recall from the first round, I was like, this is an extra round. Yeah, absolutely. We were like swinging around. So yeah, the cables themselves are quite heavy. So they were heavy, strong round, the effect is a sense of gravity and because of the cables, they are kind of hard to allow. This is Cthulhu. It was a very poor design decision but we had no time. Essentially, it's what happens when you try to get in six times two cables together and hope for the best. So now, what have we been up to in the face of all of these issues? So firstly, this is our camera unit. We did not get time to be mounted this year but we have hopes that this will be something that will make a future in the 2018 year. Furthermore, we found out that two active panels were quite resistant to movement. So we've kindly moved on to using T-Sort bars for our mainframe but sadly, because we didn't see we don't have much development, it's quite variable right now. Then finally, just some pocket mic things such as I also mentioned, pre-printing because it's cheaper and faster. Also, this is a curious little thing. There's actually a mold that we made. We used circuits just to fabricate our own gaskets. Of course, we noticed that the spec that we have was not really available on market. So these things are smaller things that we discovered throughout the design process. So thanks for explaining, I'm not sure if you have any other questions. Or we can take questions after the... Okay, we'll take questions after. So, until the next presentation, we'll show you one size, two size, three and a half.
