 All right. All right. Thank you. We can see you. Okay. All right. So I just wanted to talk a little bit about what we've been doing for the circuit breaker period. Engineering good is the nonprofit charity based in Singapore that I volunteer with. And it's an entirely volunteer driven individual supported charity. Our objective is to work with tech and bridge the digital divide, bringing tech closer to the people who really need it the most. So in the past we've been doing work for persons with disabilities, assistive tech, that sort of thing. But with the whole COVID situation, we had a call from one of our beneficiary voluntary organizations that said they have a bunch of families that need laptops. And with the upcoming circuit breaker period, kids are going to have to like stay at home and do home based learning. And the family is kind of for a laptop. So can you help us out? And so that's kind of where this whole thing started. And then we turned this into a campaign called it computers against COVID. And this is the TLDR. It started with a little like Facebook post and a WhatsApp message that we put together. And so we called a bunch of volunteers, me included, to try and refurbish donated laptops and fill that 24 laptops before the circuit breaker started. And then the families would be able to do home based learning. So the idea was we'd volunteer for a couple of days over the weekend. And that would be the end of that. But one thing led to another. The number of donors also went up. People who had devices, people who are, well, most Singaporeans, I think have more than one device at home. And so they were willing to answer the call. They donated laptops. And over the course of a month, we involved 100 volunteers, 1,000 laptops were donated, refurbished and delivered. So it's been quite an adventure. But there's more to it. And I'd like to get into. We got a whole bunch of media attention. And we weren't entirely sure what to do with it. The idea was very simple. But the way it turned out, because it's a community sort of effort, it was a little bit more complicated than that, which got even more complicated because of the circuit breaker period. And then everything had to move to Zoom. And then it got even more complicated after that once the engineers got involved. The logistics of the quality, I think, is a talk for another time. But it was quite interesting. The idea was instead of, because we couldn't have a central location, we had people who wanted to donate their laptops, have a volunteer go collect that laptop from that person and deliver it to the nearest community. Like a tech person who was willing to spend some time and sanitize it inside our Clorox it and then format it, reinstall windows and then send it for QC. So the logistics of sending things back and forth, organizing volunteers, that was a challenge on its own. But all of this was done in the sort of decentralized way where we had people who are tech savvy, shall we say, working from home and volunteering by varying levels of functionality and cleanliness. And then refurbishing them when they had a time to work on it. Some of them were really quite, you know, icky and not just on the inside for the outside. So yeah, the volunteers did a wonderful job and, you know, all of this played out in a sort of like an organic kind of way where as we were doing this and sharing this on Facebook, more people came forward to donate, more visibility, and so on. As we were doing this and sharing this on Facebook, more people came forward to donate and more visibility meant more logistical challenges, but also that meant more devices going to beneficiaries. This is kind of what it looked like on the inside. Once the devices were like reformatted and installed with Zoom for home-based learning, it would come down to a central location, which is where I am now. And it would be quality control checked. It wouldn't be to run a script that would ensure that all of the software was required that it was there, and then it would be tested before it went out. So that's how we've been doing most of the laptop refurbishing. What I want to try and focus on in the next 10 minutes is the salvage garden. So as part of the computer's refurbishing process, a lot of the devices that were sent into us were not in working condition. And those just got set aside. Priority was to turn around the devices that could easily be reformatted and sent out. But the ones that couldn't be powered on or didn't have a charger or looked a little bit like a site. Some of them were a little bit too far gone. We did have labels that came back from pieces. Well, some volunteers sent us little labels saying what condition they were in. But others, you could just look at them quite bad. But yeah, the idea was to try and salvage these as much as possible. And the quickest salvage was to just plug in a missing power adapter, turn it on, and then call it a victory. But the pile of laptops grew beyond what that tiny little space could handle. And so we were lucky enough to have a space donated to us, which is where I am now, which is the Football Association in Singapore. We are at Jalan Bazaar Stadium. You can see that behind me. And the stadium was shut down, completely turned off for better part of the circuit breaker. They only recently started some kind of exercise. Lots of healthy people on the field. But we've been using this room as a salvage garden, which is like to try and repurpose the space to do exactly this, which is organize things, get away to have as many devices saved from the e-waste pile, and put them back into circulation. So we came up with the plan, which is not as, yeah, it took a lot of iterations to come up with a process flow to sort of triage which ones needed to be fixed first and which ones needed to be fixed later, what steps to follow, yada, yada, what not. It's not going to go into detail on this, but I just wanted to point out things like, you know, netbooks and emotional attachment to these devices or what, but they'll put aside to a separate pile. We'll get to them when we do. So there's a conversation there about like using Google Chrome or iOS, but not important because it's not relevant to home-based learning. The computers that have Windows XP on them were set aside because they're probably too old or too slow to handle Windows 10, and Windows 10 was sort of like a baseline of what we wanted to give most of these home-based learning students. And the rest is to sort of just troubleshoot what process to follow so we could involve more volunteers. And so volunteers got involved. A yoga mat was installed which required somebody with patience to deal with the pile and then organize them in a way that not just one person but, you know, a community of volunteers could handle. And the idea was exactly that, you know, you have multiple devices of the same model and all three of them had various problems. So we pull out the parts that are functional and then at least do one of those three that can be, you know, sent back into circulation. The Macs turned out to be a lot easier to handle because of the consistent hardware, relatively consistent, I should say. So yeah, doing things like screen transplants takes a lot of time and effort and patience, but it is possible. It's relatively easier to do on Macs than it is on Windows systems. So for the devices that couldn't be salvaged, we harvest them for parts. So the screens, not as important, but the keypads not so important, but the ones that are most important are being protected by our accidental volunteer in the middle there. The hard drives and the... we salvaged the license key from behind to save most of these devices. So in order to get Windows 10, you need to have a license. We had a conversation with Microsoft, but they were not able to help us for administrative and bureaucratic reasons. But let's not go into that. So the quickest way we found to salvage and install Windows 10 was to pull out the license key from behind. This particular one says Windows Millennium Edition, being held by millennials. So I thought it was funny. If anything has a Windows 7 or higher, Microsoft supports an automatic upgrade for free. So we use the Windows 7 keys, save them, and then install Windows 10 and use the Windows 7 key to have a licensed version of Windows 10 be sent out. So not only were we harvesting the hardware, where possible, but we also harvesting license keys, which annoys me to no end. But let's not go there. Let's sort of spotlight very quickly on one little side project that came out of this. While we were working on this, we came across a couple of laptops that did not have a webcam built in. And the whole purpose of refurbishing these laptops was for home-based learning, and they need to be able to do Zoom. So there was a separate group of volunteers who handled purchasing, and we bought a whole bunch of USB webcams, and then we supplied those together with the laptop that didn't have any. But on the side, we found that there was an instructable that would allow for these sort of built-in webcams that we were pulling out before sending the pieces off to eWaste. We're pulling out these built-in webcams, and it turns out that it is possible to... And this is kind of what I want to focus in on, because you'll see there's a diode, and all the other cables are standard USB cables, and there's one on the right-hand side pinned the bridge. So that's the common ground. So you've got two data cables in the middle, and then you've got five volts on the left and positive on the left, and then common ground on the right. So that's all you have to do to solder on a USB cable to an internal webcam to convert it into an external one. I mean, we didn't actually send these out to the kids, but it was a whole lot of fun to work on, and it got a bunch of people asking questions about, you know, wait, hang on, what is USB, and how does the protocol work, what's the protocol? So it was a lot of fun, very interesting then. Yeah, so that is one of the side projects. Just a quick video here of a demonstration. What I wanted to highlight here is that, even though it's all hacky and soldered on like that, it requires no drivers. All you've got to do is plug it in the right way around, and even on a Mac, it just works. It's auto-magic. So it was surprisingly easy to do, requires very little soldering skills, and you can do fun, infinite videos. Okay, one more side project that came out of this whole salvage operation was the screens. So a lot of the devices came with like a black hole in the LED panel. Like for some strange reason, there would be a giant like black hole, and everything would look like something out of interstellar. So those are not salvageable, and then providing an external monitor, because the rest of the device works perfectly fine. You've got a perfectly functional hard drive, perfectly functional CPU, all of that. So it seemed a bit of a waste to get it to the whole thing. One of the volunteers pointed me to a project that could reuse these screens in a sort of, not particularly practical, but fun and interesting way. If you separate the layers, you get like a Fresno lens, and there's like a backlight and a diffuser. So all of them can be used for various things. But if you look at what we did with this... Well, hang on. Yeah, so there's a little bit of circuit bending involved, where you have to identify on the board where the power works, where the power goes in. And if you put a series of resistors in the right place, you just have a look at the sheet. And usually, depending on the LCD panel, the LED panel, it's not that difficult to do. In that, and provide power directly to it, it just turns on the backlight, and you can get rid of the LED in front. So it's always on as soon as you plug in a DC jack. And this is a DC power adapter from one of the donated laptops. So then what you wind up with is kind of a... It's just an LED panel light, which you could use as like a, whatever, tracing backlight, whatnot. But that's kind of not the point. The point was that you've taken e-waste and turned it into something that is like a cardboard prototype or something useful. So we've been sort of exploring side projects, but there are more, and we haven't had the time in patients to do that because the objective was to try and salvage as many laptops as possible. So we might, you know, what would have been e-waste. And that went on for a while. So we did 150 because, you know, we could. And then that went on to 200. And then now we've got over 300 salvage laptops that went back into the cycle. So over the last two and a half months, we've sent out over 2,000 laptops together with the whole salvage garden thing. It's been quite a mad circuit breaker period, to be honest. It's all about, you know, trying to fill in the gap where the government's policies which provide PCs and laptops to students who don't have them are not able to cover. And more seem to keep coming forward as time goes on. So what we've decided to do is continue this a little bit beyond just the circuit breaker period. And we've turned it into sort of an educational program through the maker space concepts. But, you know, because it needs social distancing. So we haven't quite figured out how we're going to do this. It's probably going to be like through Zoom like sessions. But the idea is to have a space where people can take the laptops that are left over, which are, you know, the XP pile. And since these are probably going to wind up in being collected by an e-waste recycler, we can use these as a way to give it to somebody who's interested in how a device works. And they can take it apart. They can point them to, you know, how things work. And they learn by doing rather than, you know, listening to me talk all the time. So yeah, so that's the intention with salvage garden with a combination of like online sessions and something hands-on. So we're working that out now. We have to move out of this space and give it back to the football association because, you know, yeah, they need it back apparently for whatever reason. And so we're moving to a new space and we're putting together an education program. And if you are interested in helping out, my email address is on the screen. Questions, comments and thoughts. Great. Thank you. Thanks for what you do. So as we are a bit time on time, please leave questions after the talk. So let us move on to the next speaker. So I hear Bob is here.
