 So since this is a very technical, highly detailed and sophisticated presentation, I ask you to please bear with us. There are several layers of hacks that have gone into making this incredible work of art possible. I'll try and walk you through them as best as I can. And we have on hand experts in the field who will answer any questions depending on which layer of the hack you're in on them. So the whole thing came together. We'll talk a little bit about the hardware and then we'll talk about the software since this is a hackware kind of thing. So the context for this particular work of genius was for the mixed fair, the tag being every day is a funny fair. And this was the deployment platform that we were aiming for. And since this particular platform wasn't familiar to me, we had to go and figure out what its attributes were and see where we could plug in our hack. So we'll come back to this platform in a bit. The hardware that we decided to work with was incredibly expensive. This, if you look closely, I don't know if I can zoom in here. Okay, there's a little label at the bottom that says $12.99, or $12.90 at this incredibly sophisticated foreign company called IKEA. I don't know if you've heard of it. If you need details about that, come talk to me. So we decided to try and use the MECA approach, which I think is trademarked and patented in some legal office somewhere. This was at the lab with a bunch of pieces that were lying around. I think it was a IKEA DC motor, which is very sophisticated piece of technology. And an Arduino microcontroller and two very sophisticated eyes that you see at the bottom. I had somebody explain that to me, that those one eyes. I used to believe that. It's like synesthesia, you're seeing with your ears. It's a little bit confusing. So the first challenge, the first hurdle was trying to get the hardware to connect. So we had this hardware, which was, like I said, very sophisticated. And we had DC motor, which was very difficult to source. We had to find it inside a shelf, inside a plastic box that said recycle DC motors. It was very difficult to take it out of the box. So then we had to make these two incompatible systems work with one another. And that's where the hack began. Introducing heavy machinery. This kind of hardware, again, the specifications for this are way off the charts. You could probably make holes in charts in this floor. But after all that, we managed to make one system work with another. This was the moment of triumph, where two things actually fit. So we had to do a quick test. This is a load test. You'll see the electronics interfacing with... Ooh, nice. Spooky. It works across the system. Spooky action in the system. This was, yes, the spook after fan workflow. All right, so this is your blankie lights. We've got the thinnest feature system to work with an ugly looking hand. So you can sort of guess what's going on here, right? So it's got an ultrasonic sensor, and it's looking at the distance, and based on the distance, it changes its state. The hardware looks absolutely beautiful. Some of you would recognize right in the middle there's a particle photon, which is incredibly easy to work with. It's designed for idiots like me who like to explain things and an incredibly patronizing manner to other people. We followed a very sophisticated continuous integration cycle of poking things into breadboards on pieces of cardboard. So you'll see the first alpha, which was fully functional, looked like that, and then we went to version one, which looked like that. And then we decided, you know what, we're going to launch. So we deployed it on several instances using another hack, which I think you can probably tell. There are little proximity switches at the bottom, and a $2 pair of earphones that you get from Daiso. What we wanted to do was have limit sensors on the umbrella. So this made perfect sense because it just made sense. So what we did was combine the two together using helping hands. So instead of speakers, you know how it switches. And for $2, this is amazing because you get a two meter long cable, and you get the jack, which by itself would have cost a lot more. So that worked out nicely. So this is the fun part where you make lots of them. As you worked with speaker wire before, it's not exactly fun. We got hungry somewhere in the middle, so take away containers. We got, you know, reused, made for a very handy case. This was supposed to make a fair show. The idea was to try and keep transparency, let people see the source of what's going on, and sort of follow with your eyes, the wires, and sort of figure it out for yourself. And I think it kind of worked out. Okay, third hack, power. So the system runs off of a USB power, which I think some of you might know as iMolts. I see some surprise clutches there. If any of you didn't know that, you're welcome. The DC motor on top of the umbrella, which we first interface, runs off of 12 volts. So, you know, problem. How do you make something with 12 volts and 5 volts work together? Ta-da! So that is a USB genre meant for the cigarette lighter in a car. The lighter socket. So, cars run on 12 volts, so in goes 12 volts and 5 volts comes out the other end. So this was bought, I think, for $8 or something like that, which turns out is a very good hack because if you get this as a module, it costs more. So how do you make it when you do this? Only because it looks cool. It's nothing else. So that's what we have up and running. You can see this later on. The power system puts out 12 volts. 12 volts goes into the little thingy and then you have 12 plus 5 in one system. I highly recommend you do this for everything. It's tremendous fun. So, what we did was multiply this several times and then deploy it with a little quick user acceptance test that involved using the client's bum. I think that's the software part. This is the back to the platform where the solution has been deployed and I think if you could just show you what it looked and felt like so as people pass by, the umbrella would shy away from human presence. So what we designed was a shy umbrella so can you stand under my umbrella? Okay. What happened later on after the make of head was the Singapore night festival which is where I think two of you saw what had happened to the umbrella. So it went from being just a shy umbrella that didn't do well with human presence to being something a little bit, which is something that's really unique to everybody in the room. You're absolutely fine with human presence. Everybody is okay with social communications. I totally empathize with that. The umbrella on the other hand, weird creature. Doesn't quite work. So for the night festival it needed some lights and then we had geniuses that is Kathy and Donna who are in the room who decided to turn this little umbrella into something that was even more, which was a jellyfish. So then it stopped being just a shy umbrella and started being a shy jellyfish and tentacles hanging off the middle. We wanted to put like live AC-AC current through the tentacles but then there was kids around. That was seen as not a very good idea. Perhaps in the next iteration we'll do that. So do you want to talk a little bit about LEDs and such, Kathy? So the LEDs that we added in, the first part was just the normal Christmas lights that can do blinkies or street lights. The other one we did new pixels. So these are programmable LED strips. So it was actually quite easy to use and you only need a single little light to do it. So it's like even though we have a thing like almost 100 LEDs in there, we only need one single little light to stick it right in. And the library is available from the program as well. So yeah, it was great. Simple. Yeah. Cool. It was great. Well, then I have my second play with it later and come in next year. Cool. All right, thank you.
