 In previous years at LTX, Jake's contribution to like incredible experiences that we've created have been playing racing games on the 16K and 10K ultra-wide gaming setups. And frankly, they were smash hits. Good job, Jake. But this year, for our racing experience, we're not content to settle for bezels or even virtual cars. This is next level, my friends. What if instead of a video game car on a screen, we could drive actual cars in VR? I mean, yeah, okay, they're RC cars, but like, come on. Close enough, right? Sick, right? That sounds pretty cool. Just like our sponsor, Ridge Wallet. Ridge Wallet is the sleek way to keep wallet bulge down with its compact frame, and it offers RFID blocking interplates.

So first, we've got to figure out how to control our steering servo here with a steering wheel, as well as figuring out how to control our ESC or electronic speed controller with a throttle and a brake pedal. And then there's the video stuff. Like, how do we even mount it? What are we going to use? There's a lot of questions here. Yeah. Furthermore, getting that video feed to the headset is another issue. So we need something that's high quality enough that you can really see where you're going through it, and also low latency enough that you don't just want to immediately throw up. We're probably getting ahead of ourselves a little bit though, because before we can do any of that stuff, we need to settle on a platform or a car. There's a lot of options out there, obviously, but we need something that's not crazy expensive, because, you know, you're kind of cheap. We need something that's going to be reliable with good battery life, because this is going to be seven plus hours for two days, and it needs to be not too big or too fast, because both of those things are going to contribute to motion sickness. Yeah, if you're like ripping around, like, that fast, like four inches from the ground. We want to keep our vomit quota for LTX pretty low. You're going to be done. Now, of course, it also still needs to be big enough to house all the first-person view hardware, and, I mean, ideally be fun to play with when we're just done this project, right? Yeah. There we go. So, it turns out there was a bit of a miscommunication. Jake and I define large a little bit differently, so for better or for worse, we ended up with a Traxxas Slash two-wheel drive, which would be perfect for this project if it was, oh, I don't know, about 30% smaller and... Maybe it's, okay, okay, okay, maybe about a fifth of the speed. It's fun, though. Yeah, that's fine. We can roll with this. All right, all right, all right. Well, one thing I didn't show you is it has training mode, which cuts the throttle in half, you know? Jake's not so bad, eh? We're on the same wavelength here, eh? All right, it's still pretty quick, okay? Yeah, it's still probably a little faster than we wanted. Sorry, David. Getting our steering working with a USB steering wheel was the first real challenge. Now, we knew thanks to fellow YouTuber RCSparks that there was a steering wheel that would work really well for this setup, thanks to its simple design, the Thrustmaster Ferrari Racing Wheel, and thankfully, Thrustmaster was able to supply us with several of them to Tinker, and it looks like with some minor modifications, we should be in pretty good shape. So with the RC transmitter and the steering wheel opened up, this actually looks relatively straightforward-ish, hopefully. Knock on wood. So the transmitter just has a potentiometer, so you can see the one behind the steering wheel right here, and then it's got a second one for the throttle, so that's pretty cool. So if the resistance is the same between this and the other one, is the same between this and... There we go, the potentiometer here, and well, the other one would be in the pedals. We'll deal with that later. We should be able to just move the wires over, and yeah, they're different. So we're dealing with 10 kiloohm potentiometers in the steering wheel, and then just... Five. Five kiloohm, not just five. Yeah, sorry, yeah, five kiloohm for the transmitter. Okay, so hopefully then what we can do is find some five kiloohm pots that are a similar size to what's already in the steering wheel, because we'd rather not have to make adapters or something just to mount the pot so we can turn the stem on it when we turn the wheel. After a quick trip to the local electronics store, Jake returned with something reminiscent of what we previously had, although we could tell some minor modifications were going to be necessary. For the pedals, we weren't able to locally source flat-sided potentiometers in the resistance that we needed, so while you could probably just drill out the hole in these little gears, we decided to instead 3D print some replacements. As for the steering wheel, the potentiometer was really close to fitting, but some cutting and sanding was required to get it nice and snug in there. We went with a super professional hot glue mount for now, but by the time we roll this out at LTX, it'll probably be upgraded to JB Weld. For wiring, we followed along as closely as we could with RCSparks's guide, and it turned out pretty well, although we did have to swap our pedals from left to right as they were reversed. Okay, so theoretically, if you fire that up... Turn the steering wheel... Ah! No way! Okay, well that's the easy one. Okay. You saw it. You saw it twitch there. It's definitely trying. We should try the calibration thing. Whoa, whoa, okay, you're gonna break it. So what we're trying to do right now is calibrate the pedals, because theoretically you can set up what I guess would be the receiver. Yeah, the speed control. You ready? Yeah. Okay, ready? Did you already press it? No. Oh, sorry. Well, it's moving at least, so we got the throttle. Is that enough to get it to go? Oh, not very fast. This might be better though. It's a little slow. She'll be coming round the mountain when she comes. Yeehaw! I feel like we have less throw than we did in the controller. Right, because you've got that trigger. Because these are different potentiometers. So the ones in the controller are 180 degrees, right? So you have blah, blah, blah. And then these ones are like 270. So what if we cut this? Just cut the stoppers out. So while Jake chops up the pedal assembly, it's time to talk about the first-person view video setup. Now we browsed a ton of different tutorials and forums for information about what the best individual components were for a setup like that. And the conclusion is that it's kind of like building a PC, except rather than what CPU, GPU, and RAM you should buy, it's which video transmitter, receiver, camera, antennas, headset, and batteries. And there's a lot less community consensus on the benefits of certain parts over others. So at this point, it felt like throwing the company credit card at an RC shop and validating a bunch of different stuff ourselves might have been our only choice. That is, until we found out that DJI makes a pretty much plug-and-play first-person view camera called OcuSync, which when paired with their racing goggles, supposedly provides a super low latency and high quality video feed. You know, I gotta say, as much as I was genuinely looking forward to cobbling something together and tinkering with it, given that we're going to be running this at a live event with thousands of attendees, I'm actually pretty happy that we found a pre-made solution. One point DJI failed to mention to us, however, is that... See, this right here is the receiver and camera module. It actually needs active cooling. Otherwise, it can overheat. I mean, I guess that makes sense, given that this thing is designed to be used on open air, like racing drones. But anyway, it's fine, because we can just simulate that airflow with a little 5-volt knock to a fan, a 3D printed bracket, and then some of these old EnzoTech heat sinks. Okay, so now that Jake is pretty much done with the hack job behind me, I guess it's time for me to try and find some places to... Oh man, through the grill? Well, look, it's not... I know it's not going to be perfect today. Think about it. What we're going to have to do is cut some holes in this top, but... Yeah, later. So we don't mangle it for LTX, we're just going to temporarily mount it. Yes. Because for LTX, we want it to be very pretty. And pretty is not our specialty. And think about it, it's not like when you sit in your car, you don't have your dash in front of the windshield. We'll be able to see well enough. Look, it's not! It's going to be right in front. I know. Look, if I could put it up a little bit higher... So this is the windshield right here, right? Yeah. So this is like a supercar or something? Sure. Oh, hot glue. Oof. I'm just putting a little bit. Okay. Well, it has a bracket, you know. Well, now it's hot glued. Hopefully right side up, too. You can flip it. All right. There we go. That was quick. That's on there. Oh, please don't hot glue that. Well, just a little. Oh, no. Just a dab. Okay. I forgive you for choosing this car. That's expensive. Because it's not actually that bad. Because it's working pretty darn well. Yeah. Easy for you to say. Did you pay for it? No, but neither did you. Yes, I did. Well, Linus Media Group Incorporated did. Who's that? Woo woo woo woo. Okay. So now... The battery. We need the battery. Yep. I'm not going to hot glue that. Yeah, don't. This is a lithium polymer battery. I would strongly recommend not hot gluing one of these anywhere. You got to rip it off. Just tears the cell in half. That's a massive fire. Yeah. Spicy. Hey. Hey, nice. All right. So the cooling fan's going. Is it super wide angle? Yeah, actually. Holy crap. I can see David right now. Really? From where you are. All right. 720p right now. So this is, I think, the highest quality setting. It looks pretty good. Like the lowest latency setting you mean? No, it's the highest quality one. Oh, really? So the highest latency. Oh, okay. How's your nausea? I mean, the fact that you're moving isn't helping. But do you want to put it on the ground? I want to try it. All right, you can try it first. I think I get to try. The spoils of my labor. Where are the pedals? This is going to be kind of interesting. Watch me fall over. Okay. All right. Is the soldering iron hot? No, okay. I feel like I'm driving a Jeep. Like I, oh man. No way. Whoa. Oh my gosh. Dude, the latency is so low. So we think it's possible that we can insert an SD card right here in the OcuSync and record straight to this. So you guys will see the full quality. Isn't it sick? Hey, Jake, what's up? Dude, this is so awesome. So cool. The graphics, the graphics, man. It's IRL. Man, I could get like way better at this with some practice. All right, all right, all right. We can wrap this video. I can go, I can go do my show. Okay. There's definitely still some progress for us to make before we can deploy this at LTX. But like, wow, this is genuinely really awesome. I know that this one was a little bit sparse on the details, but the truth is that this was just proof of concept. We've still got some things to iron out. So the next video is going to be the detailed guide for how you guys could do this with similar gear at home, trying out the track. And then of course, we're going to be teasing the full experience that you'll be able to have at LTX 2019. Speaking of experiences, my sponsor Segways are an experience and a half, are they not?
