I'm Huey's as fun. That's fine. That's the correct run for three days. Yep, tell us about.

you guys do well. We built a 3d scanner that's powered by a smartphone. So essentially it's the opposite of a 3d printer. What it does is you put an object in front of it.

It's got a green laser, sweeps across the object and basically turns it into a digital model. Well, how does a smartphone? Well, the big thing about the smartphone is that you have a camera on it, a really high quality camera. and today's smartphones are really, really powerful. So what it does is basically as it scans across the object, the laser scans across the object.

It uses the smartphone to essentially we rebuild, rebuild that object in 3d. so it analyzes that line as it scans across the object. Why? Smartphone And not just a regular Pc? Well, because smartphones, it's something that everyone has and it's a big factor in reducing costs. So what happens with 3d scanners? You need three things.

You need a camera, You need a lot of processing power, and you need a laser basically. And two of the three. RF Smartphone I Pretty much everyone's got a smartphone, so sigh, why not? Why bring by bringing your own smartphone User should reduce the cost. Got it all right? Just a hobby.

Well, here it is. This is the prototype. It's all right. Just the Koret are bored.

Okay, so we got a smartphone, so the camera is of course facing the object. here. Objects there. it has to be on a black board.

Basically, just get rid of the background. Doesn't have to be can be any color right? Okay, because we're in a public space, you know? Yeah, but it can't be a complex background. Otherwise, it can be anything. They come as long as the stationary can be any.

Becker are stationary. so it uses motion to motion to detect exactly exactly Hey Carter What is on the breadboard? Well, the breadboard is actually we've been using for a while now. Yeah, we have an Arduino on their pro Mini. We have a Dr V 8 830 for motor controller and let a couple voltage regulators but it's hundreds and bluetooth.

Now that's our evaluation board. Arduino is actually doing nothing at the moment, right? So that runs off an errand and zero and everything is Bluetooth control from a smartphone. How did you get that here in one piece? Without it, we have a bit of experience for that. All right.

Okay, all right so show us. can we Can we see it? Do run a scan. Yes. I'm sure let's run a scan All right.

So what I'll do is I'll restart our appt across can object comes up essentially object a little bit in the field of view. Yeah. and we just press stop go and we can't see the laser. it'll it'll come up.

It'll come over a couple seconds. It's a green laser. It's a green laser. Yeah, Oh there it is.

So there we are scanning across. So basically we use a green laser because it's essentially twice as sensitive most CMOS sensor twice as sensitive to green compared to red or blue. So we get a basically better sensitivity. And yeah, so what it's doing now is this a setting exposure and then it'll sort of sweep back on itself and I'll start scanning the object.

Why did it sort of I Do it in little bursts, education the data, and basically what it's doing is trying to sample the entire scene first. and it's trying to essentially get get the exposure setting. So just to see how much light, how much brightness is just the camera for ya and then it. It's doing the scan right now.

so what is doing it will take about. it will take about two to three minutes for the scan across. And so right now what it's doing is essentially taking snapshots off the off the object and then analyzing the beam as it goes across. I Can see it moving a little step each time.

a little step in time. So what we've tried to do here is try to build a really high precision scanner. There's a couple of scanners in the market, but they're Very. they're accuracies really itself.

we're big. Oh, this is ok. but for something like this, we want something that's very high accuracy. Got it? And you guys are made this little thing, the ugly scanner itself.

Or is it just basically some nice No. basically one hundred percent electronics, coding, and industrial design. Everything is done by us. basically us funds Rahul Enricher in the back over the three co-founders and we're basically kicks our end of September That's our launch date for what you go-go will be about eighty thousand or so.

Yeah, yeah, yeah, just for the for the nature of our products, we think it's It's a good goal to annex way here at the World Mica Theater. Yes, basically. September 27 is the rule maker faire and we tend to launch at the world. Maker Faire paint It and probably going to Kickstarter campaign literally at the event.

How many other 3d scanners do you expect me aa probably few, but uh, but I don't think they'll be one exactly the way our scanner is and especially at the price point. Early bird is. they should be one 9999 early bird price. plus the picture.

Yeah, so good. I Think you'll be hard-pressed to find something in that price range. Can we see the electronics inside one away or you don't have one. They talk suicide 10.

That's you there. We go there. We go there, we go. have a look.

If we had one more day, yep, this would've been working right? Okay, so basically if you have a look at it, yeah, that little blue tubular module there. Yep, that's a little unit right on there. Got it? That's development board and hairs are actual on circuit so everything's been done. Just go upload the firmware and we're good to go.

Yep, and that's got a little stepping motor driver in it doesn't That's got a lesser Drv a 34. Yeah. so Stepper Motor Driver Bluetooth Controller a couple of filter caps and a little things. Here is energy.

Yeah, that's it. Oh thanks, right, nobody's good luck it. Thank you for that fake food. Alright I'm here with Matt You might have heard us.

Well, you haven't heard of Mad when you've heard of his company Breadboard Killer. So tell us all about it. What do you do? Yes, Yeah, well. we are a printed circuit board supplier in Australia We Yeah, we started off batching orders together printed circuit boards and that started a fatty year in a bit ago and so it's like a side thing for me.

So I started off doing that and my goal is to bring it back to doing that. but at the moment we're offering more flexibility so you can kind of order your boards with you know, like customs, sada masks and stuff like that. and you can get like four fourth out of trace facing if you need to walk. Yeah you can get down to 44 which is I haven't had anyone do that.

Yeah, which is pretty insane. Yeah that usually costs a lot more to get down. Yeah, it does cost a bit more. I think it's 40 bucks extra.

So right. But yeah, So it's a stray lien. Printed circuit board Squire Yep, how much? how much here? boards. So if you want a five by five centimeter board, it's $25 plus shipping.

So that ends up a thirty-six bucks. Or if you wanted a 10 by 10 centimeter board, it's only five dollars more. So its up as $46 with the standard shipping. And how many boards to yet? Yeah, five boards get five horse.

Yep, when I was a boy. Not if you get one board for like 800 bucks. Oh yeah, yeah yeah, that's in forever. So we obviously know where they made they made a choice.

A is do you take the files manually in, do it. or do you have like a wash park which might be able to make it processed. So for a two-layer design, you can upload your Gerber's directly to the website. You can in like just zip your files and drag and drop them.

and then you can kind of like select. You know which layer goes where If it's not a standard format, otherwise it'll you know. guess which layer which of you LTM or Eagle standard outputs. So does it show you on that website? Did you show you like a preview of thee? Yeah, it does.

If I can get it to show up at some point or I can show you on my laptop. There you go. So you kind of just like drag and drop your file. Yep, it'll upload and then you can see renderings of your board.

You can see the layers and you can select which way as which and all that kind of stuff. And on the next page you can like select solder mask and it'll render it in red or whatever so you can see the colors and stuff like that. How long will it take you to put together? Yeah, all that stuff is that easier? not super easy. Took about a hundred fifty hours coding ya know? If you like that's a lot I don't know.

Yeah. So and then I mean that was like to do the base stuff and then I just like kind of progressively work on it I like okay so do you penalize Pachem with others that you do? No, not the moment. my menu the manufacturer I use actually penalized them. so that's why it gets the cost down.

but they get up. They aggregate like orders from a lot of other people I'd So much about you? Did we do files? That's right, Yeah, yeah and so my goal is to move it towards in the future. I Want to be more like the Ash Park of Australia and like there are a lot of people in Australia who get PCBs manufactured and I you know I want a local service? That's quick turnaround. First, the breadboard killer.

You know if you can replace the breadboard, then go ahead and do it. you Know I think it'd be awesome and so the lead time is did you? So at the moment if you use standard shipping it's about three weeks from when you order, it's when you receive it and if you go express shipping it's a week and a half. That's that's pretty good Week and a half. Yes, any plans for like a real Express service like out like a 2-3 day tune.

Um not at the moment that I have to see if there's like some demand for people like really want that I tend to find like the price really skyrockets when you look at that like 250 bucks a board. and I mean most hobbyists makers which is who This is mostly aimed at. People like me who want to you know like get the prototype up and working. you know, don't sort of 300 bucks to get your design here like no exact two days or you know, a few weeks O.o whatever.

Yeah right so it mostly Australian yeah yep yeah much very large. majority is Australian clients Yeah Thanks man. Hey very welcome Out Breadboard Killer Dot-com Donate. Donate you yeah oh yeah just to be Ozzie Alright thanks man, you're welcome and I'm here with Peter from Robots and Dinosaurs He's going to tell us all about he's funky.

Um what is it This is So this is a video game Kerbal Space Program. I have built a hardware control interface to let me control what I'm flying in the game and give me readouts about the status of my ship's got it. So it's a basically a heart custom hardware interface to an existing the Kerbal space program. That's right.

So otherwise people normally just operate it with the joystick or whatever and with the joystick, your keyboard and mouse. Its first grade, but it's kind of boring. Yeah, well tell us about the hard way. I was running up what's it got? so I have to Arduino is on board.

One of them manages all of my switches and my dials and has a serial connection back to the game I have a second Arduino that just manages these displays and the LEDs we've got it and all of these light up. They do light up a lot for about this is for launching a lot of it is good for launching I've got parachutes and heating so I get to find out if I'm about to explode. Got it? Where is the ACA de Aux button? We need a CEO ox that's coming in Version 2, right? Excellent. How long take you to build a about a year and a half off and on? Yep.

I started planning around January last year started buying components around March last year I mostly finished it this week. Oh man, just before me. Just yep. just in time I was grinding for crunching fairly hard.

Yes. Fantastic! And we can drive a Rover on Mars as I did yesterday. Yes. Fantastic.

So what else we've got done? You've got to. I Love the analog Vu meter analog meters those currently aren't hooked up. They will do. Ah, that's also coming very soon, but I'm intending those to show my speed and descending and our attitude will be beautiful for landing with Andy.

I love the blue LED displays though. it's absolutely gorgeous. They are just something or just those from a friend's a little bit here today. Oh Fantastic! So what are they show? What can you program they can go, can program them to show all sorts of things.

arm when I'm in orbit I can show my appt 0 abscess in periapsis which are highest and lowest parts of an orbit I can show how much fuel I have on board none right now because this is an electric rover I can show when I plan for a maneuver I can show how far away that is and how much power I need to use to get there and I can show my altitude. So right now it's telling me that we're at two kilometers above sea level and that's about it. Sea level on Mars Where the sea would be? Where would be? You're right. I Guess there's a mean where they just like on you? Yes, Got it? Fantastic! Thanks! Peter Thank you.

Now here we can tell us about your podcast. Hey! I Put a weekly science technology if you? want wacky, weird, unusual, funny science every week. Awesome Diffusion science radio. A Diffusion radio.com A Diffusion radio.com There you go folks.

Scioscia's stuff all right? What aren't around with these are podcast running around with my mic is microphone. That's right. Show us your on the stuff. Got the neopixel goggles yep and what you mind this time I know you put a mug you yo mojada? Yep.

awesome and you've got a head mounted camera and I've got a little head about a camera is that currently on? it's not them? Nothing off. it's just I down the battery for it. Look, it's a look see that I've modified. yeah and look see, don't make them anymore.

All right so it's not fully supported anymore and it's better if I just record when I want to record kind then switch it off. Got it? Awesome person! Benton Thank you! I'm here with Nathan from the Uni of New South and he's going to tell us all about these fantastic little Pacman robot things taken away Nathan So we're a group called Create at the University of New South Wales Where a make a club and this is our latest project. so this is a robotic Pac-man game. Excellent hands tell us about the tech in it.

So um these little robots are running Arduino is inside of them. We've got these stepper motors on the bottom here which ye the same as the ones in your 3d printers and they're used to drive the robots around with these omnidirectional wheels to allow the robots to sort of move forward back, left and right without having to turn. And we're using these infrared sensors to do some our line following basic line following on an interactive course with some image recognition because you put some lives in here and there. The dots, right? Yeah, they are.

So they're the dot Packmans It dot. Yep. So as Pac-man moves around the course, we've got a little overhead webcam and it keeps track of Pac-man and it turns off the dots as Pac-man goes in. Excellent webcams all the way out there.

That little tiny little green dot so so I can even show you a little bit of, um, what it looks like on this program. So we've got Pac-man moving around and the webcam is actually tracking where Pac-man is and we've got the blue ghost obviously on screen as well. How long did it take you to put this together? Oh About five weeks, not very long. Ok, so she did this actually for the fair.

Um, we did it. Actually it was originally for our Vivid, but we've improved, improved that since then and made it ready for the fair. So no, it was. Um, he was actually at Unsw Art and Design campus to begin with.

So it's a bit off site, but but this is such a massive event we wanted to show it here for a long time. Does it play a mean game of Pac-man? Oh it. It does Army to work in progress. So we're setting up like a Wi-Fi network to send all the robots information about the location of all other robots so they can make smart decisions so that Pac-man can avoid the ghosts and the ghost can chase after Pac-man It's really exciting, thank you very much.

I'm here with Aileen from the missing Link and she's going to tell us all about this. It's not chain mail. What is it? It is scale mail. What is scale mail? Scale Mel is made with a bunch of tiny little scales like this or like this and they're all joined individually with links.

Kind of like chain mail. Awesome. But instead of joining up the links to themselves, they linked into scales. Now, this style of armor has been around for ages.

This is before chainmail. Yeah, actually it was a precursor to chain mail. There's about a thousand years before Hand was about when it started. Wow The Japanese were very fond of it.

They used to make it out of paper, leather, metal. Anything that they could come to hand. The scales weren't necessarily this shape. they were.

You know, other shapes. they used to have a min squares and rectangles, things like that and they join them up with either links or leather or they time and how long does it take to manufacture of that This took me 22 hours. 22 hours is a yellow. my character more than that.

I'm pretty fast all right. Yeah, the chain around it, the actual comes, custom bandolier to hold it on. That took me six months, six months. It was the first piece I ever made.

I Was just learning at the time and it gave me the basis. Fantastic! Thank you very much. No worries you you.
