" trading your aeronautical engineer. Engineer into account it can't quite -- an engineer but look pretty close pretty close. Well -- that you dead things like my personal favorite involves 24 hours a bicycle and a lot of applications -- you actually different -- code Jessica and I we've built by candidate all the aerodynamics and some of the structural design on it and we built it so -- being the athlete he is the -- went 21 street inside this bike. And went 650 miles. So. It's more than most people can drive and Andy and he did that with his legs so it's pretty impressive and that was at a world record gets it is that's pretty cool you've been involved in setting much of records not so much for prices lately it's been very human powered land speed records right. But you're not the guy inside like the bicycle all -- on the geek behind the -- we've got one very talented designer and everything record Jessica Kia. He'd you know doesn't have that is especially training and more graphic artists so at the same time he's he's one heck of an athlete of all time iron man finisher he's even qualify for corner so. Using him as the engineer all right he's he's getting older and it started using before my engine basically wears -- its passage -- it aerodynamics design your buildings vehicles yet. What's your favorite tool for actually doing I am I and useful works is that through its content package that's what my business. Purchased two used there's a lot of other packages out there are still works is quite expensive but you can go right to free if you go to Google sketch up keeping going is that corporate tool. In fact it's probably the best way to get started in that circle by the time if you doing high -- engineering or something a little more technical hole works is good there's a few of the packages out there but. That's my preference and it works quite well soon. Three -- obviously you're dealing with -- engineering you're dealing with modeling in in the insult works. How do you go from solid works too like a thirty dollar basal level and a netcam. She skated designs is really cool well."

" I'm Scottish play -- time machine -- actually -- and -- of the cheapest one out there is what port 500 dollars for -- hardware apiece sort of from high -- digital quality -- yeah you know what you can -- things together and with this one it's a little more scalable but the fact remains is this quite expensive and there's a lot of you know if I'm dealing with their dynamics a lot of organic shapes and -- really hard to models better if you kind of make it by hand in this and it. So I'm I was looking online when Tyler voiced an interest it and then there's different ways to skin things there's one called photograph retreat where you take several pictures. And you can actually generate three -- off a bit but it's not all that accurate. You've got mechanical arms scanners they're good but they're really -- subject to the user's ability to use it and their more expensive -- laser scanning as a hardware is very expensive. And I'm you know there's there's -- different things -- laser scanning seems to be fairly effective but again crisis coming down but not cheap enough. When I was looking online and and it on this David -- laser scanner dot com. Has if you engineering students in Germany better obliterated their masters on this. But they're offering this software for real cheap -- actually get the scanner for free but the middle -- surfaces together you have to pay port but even and it's. I think -- 200. Euros or somewhere close four for the high end -- we still -- currency time this -- there that are feeling. Fiscal crisis here just there aren't don't know it's very true but hey. So you basically you take that you can go get wicked cheap laser level and a cheap web camera know the more money spent on better equipment what you get and I really good web -- that helps if -- really -- leave the house need to find those but. I've built one for thirty dollars now -- garage sale items and in the fact is is that. Not everybody needs something to be darker -- I -- these want to get the shape we'll look at."

" It takes time of -- book. Accurate within 5000. Is that five -- buy thousands of and by thousands of image on the return like a couple of hundred dollar decades of the highest -- and camping is supported by authorities the right. And what heavily user at the high end high thousands of and it's that's. Yeah that's. Pretty delete expletive accurate oh yeah absolutely it's time and I think this is it again you gotta -- decent laser for this and even you take another step mostly disease here -- I'm getting during spectrum later -- scans better but you're back at the same time you can buy -- how many watts does blazer for probably about sixty dollars. Which is about as -- and as you possibly want to get that apparently -- here unfortunately for the cheaply there is apparently I was getting my Scottish on. Are I don't he's going to work for yeah I've actually tested both of whom they both worked that one is got time. Some major issues with a line you can see the light gets brighter and dimmer and it'll still scant it's a little bit awkward. Five -- this one has a little better aligned that you really don't have to worry too much. Both accuracy and fact you can even use if you can generated is -- shuttle it's looking -- apply actually. The couple sheets of paper really close together and predict line you use outline as well."

" We've got a two lasers pointed at the -- here right. And what are we looking which one of these is better than Apple does a better you can see more consistent line and it varies very little as far as -- goes from one end to the other. For a link within a certain range but this one's very great at one and there might be a reason for going to lecture. But the fact is that that line is a little wider than. A lot wider and then down at this and so makes it really hard disk and Microsoft -- gonna comedy that that you start losing -- is. That goes but. You can even go as far as to take he. Laser pointer just appointment if you can find it winds down currently the -- he grabs them. -- quite the dot -- for the Stanley it will make a like a lot so its its you know here. You're really really frugal and you gotta go -- you can the laser pointer."

" So if you if you want to go for the the high end the creme -- the -- blazers weren't looking for. You know. Generally.

So I'd need to take about four or five different scans all the way around. So that I can take those different pieces and put them all together to make 1360. Or water tight so that would be the -- yeah. -- Yeah you gotta pressure in your print. Calibration pattern. The calibration pattern itself I've done around eleven by seventeen that you can do it on the half by eleven this is all scalable and like you like it. The little tiny thing and scanner coin you absolutely could and you just try to make television pattern fit. About the same size as the object in this case we got you know. -- And that we can use an instant. So you -- scaled to -- if we're going to court you're an with a certain design of the surface of Columbia socialist -- two inches by two ounces yet it helps if you have a high quality of these for that you know it was a -- very thin and -- if you scale it down works really well and again it comes into being able to get -- camera where you can actually focus -- Because what cameras generally are sent at a preset focus. She can't get closer to the calibration coming out they'll focus the work that point is that it was -- TiVo why it would camera -- not say higher resolution digital camera you can use those actually can what you do is to use the digital camera and recorder movie. Now I'm gonna have to show how you can adjust the camera settings so that you get the best possible image to do this can. But you can totally record knowing -- tricks is you can record. The game itself do you scan and then after what's all that's been done is put the recording into your computer. And and use the recording as as these can -- the things you don't even have to example a camera if you.

The -- boat immediately executed twenty simple loophole that you've printing giant version that's we will be found 190 degree you know again accuracy so you have a very high hacker -- recorder and a and a sharp that we need to -- yes exactly. And it was very hard to find but we did we managed to sort of work you know -- for the actors who we needed and it the -- the corner of this one -- was fine. We painted it wait and then what I did is I got time I've measured over all of these point and as into the model law so -- to steal -- So that worked with a -- forces of order or -- like four feet apart you know they were -- are you part you know while."

" It's just yeah. Times are asking it is basically we -- the program itself we calibrate the corner so we. Make sure that all the dots it knows where all the dots are and the way it works is is that believes in line. When you project -- one lining hears him coming at this angle and how to coming at an angle to the camera itself so that it can view properly. Now this software knows that the line comes in at this angle when it comes in at this angle so. Whatever object it's hitting and where that line is can only exist in one point 3-D space and that's where the software comes and it calculates where that point is. As such areas surface on it on all these points and it craps. So do we actually leave the cameras in a single point -- person yes. You do that's critical. What you've done everything -- I just put up and -- quite what you said it it's like you know you don't want to reveal want to move it but you know there's different things you can do if we took out some -- and we just made like a little tripod and to hold this. Come look at there we have all static you know if you have it set up in one system. You could make it so that you only calibrate once and once you've done that you never have to calibrated again because you know that that ninety degrees or you've been locked in. There's another really cool thing at some people been doing is that they calibrate this but they make this in this section here actually followed. So as long as you how that one might hear one line there you can actually take this whole thing if it's on amount in place over top of an item and scan it. So can be in the background is like it has those two lines that'll still -- on -- hosted at the time on how to -- Well what we do is. Going to via software itself. And open this up and we see we've got the camera itself. -- the settings. This is the way things have few things he want to -- is a black and white images -- the best means it. Get rid of all the saturation. And then you bring it up. And you can actually see. Those dots AC hope stark black and white that is yes that's what you want to actually go for so you generally want Kong the contrast that -- The thing you can deal with is like the exposure and the frame rate -- fifteen frames per second this is more inadequate. But in this case what we'll do is I'm gonna just repositioning camera little closer. Return overly these little red x.s owner -- spots -- exactly so. Now we've got the camera so it looks really good one problem we're gonna have -- is that is going to try to find these boxes conceal this area here. Is state U via a handy little. -- brushing -- paint over here you want it to ignore. You don't always have to do is you build the calibration quarter rate you won't have this. Have to deal with this but generally only do once. You hit calorie and they'll say calibration successful. Again also it actually moves the sponsor. That's very you can you can manually do it but you know why doesn't actually look up that would take me a few minutes and then this is this so much easier. So we go that. I generally reset it so that you can't. You can't you were painted over anything and you still gonna put the camera settings at this point when I end up doing is particularly user itself. And treated in this -- that so it in in the view. And we start playing with the camera settings again so that we can -- lying believes that line and only the line. And in this case is gonna be pretty hard it is regulates it really -- and hunted him down -- rooted in the stimulus that costs. Break here you can actually see where that late is being reflect off the weight but it hit one of the dots and it's a little bit is that the Japanese are right there yeah. And you get that is like he's young -- clean and the contrast is great. So this point what we do is we place to be penguin great recorder. And we can literally start scanning at this point so. You normally scan like you talked about doing a vote whole warehouse -- it right. Food warehouse that felt better now and it was it was bright enough that it really was bigger -- that is really creepy when it that until I hit apply with a camera settings. -- and this is where gets final what I wanted to do was hold your hand up fairly high at least twelve inches above the camera and you want to be certain distance and you're gonna rotate the line you're not going to sides. And the line you're gonna rotate it with -- She starts scanning down and watch the screen as he scanned down when she hit the penguin itself you'll start giving you the point clock. It's really easy now to more daddy get you keep the -- you -- yeah you can go button again this is what postings were. It refused gather going to suck but you're gonna learn how it all works right.
