Hi Welcome to the Eev Blog an Electronics Engineering Video blog of interest to anyone involved in electronics design. I'm your host Dave Jones It's because true, but it's not sort of to the ideal of how to build a rep rap. It's not that that part there on these printers is about a 2hour printer. So yes, they actually prefer them printed because when they mold them they they tend to be not as well made.

All the internal holes and things that are see these are all the prints that he did on this. Yes, that's where these come from except for this one which is uh and um yeah this creamy colored one is ABS all these others are pla that's quite quite durable. Yeah, ABS is what they make cars out of. bumpers and dashboards and things like that durable because this this is just a bit more brittle.

y um this is my rep strap here that I've I've made up to um print off the parts from my rep wrap printers right? Um, we've made three of them so far. or making three of them so far. one for the club and one for a couple myself. another guy.

um this one's actually just about finished right? All right. So what? So this machine here actually is just designed for duplicate manufacturing. It's will print everything that one of these will print right. Just when I started it I couldn't get couldn't get access to the printed parts.

so I thought well what am I going to do So we went made a wood one made a just a jewelry rigged rep. Absolutely okay. and it's that basically using the same instruction what's on the yes pretty much this is actually on the site as a wolf strap. The basic design is there.

It's got my own variations on it, but it's there is a design fantastic and you've produced which parts on here. all the white Parts here this will be more and the red part there by three different printers. oh okay, uh. two and a half.

Excellent. So this one was printed on a slightly different PR is not. um, this this prin actually rods here. he's just about got it working.

and I got me metal cutting machine here today and you've got a what have you got? This used to be a key cutting machine. Oh okay, and we've just attached steppers to it Y and sort of, when I get clear of this one working which is tantalizingly close, I'll put a bit more effort into this excellent making bits for model steam trains. Oh Fantastic Model Raway all sorts of uh, 5 in 32, 7 and A4 Uh, we're going to have the Australian convention in 2013 2014 up at Bull right Nice up near the airport. Excellent! Love model trains and I love the rep.

R it's very cool. Very so how how long it take you to build? Um, it's probably about uh, 3 or 4 weeks worth of build time, but over probably four months Y right? Okay, and and and how's the resolution on it? Is it? It should be identical to the the rep. basically all the electronics, all the motors are identical, right? and the and the Extrusion head extr. The extr head is the same.

so it's just the fact that it's on a different frame. um which is actually allowed me to get up and going very quickly because all the settings are pretty much the same, right? Nice. And is that the what Diam is that that's like a goes down to a half mm Extrusion at the moment? Um yeah. Excellent.

So that was my very first print the the spool. Oh okay yeah. Actually manufactured the spool itself. Okay, nice.

and yeah, that's well done. So so the platform moves. What? Yes, so platform moves. Yep, that way this yep and that'll go up and down with the and how long does it take to print Parts uh well that part there y was about uh, 40 minutes, 40 minutes.

Yeah. and this part here which is a bit larger, that's about a 2our 2our part. So but one of the things you can do to tweak them is speed them up quite a lot. All right.

well done. Start We're here with Paul and Paul's got a and open PCR machine. Yeah this is a P it's a What A DNA analy DNA cop ma DNA copy machine. Unfortunately the light's not that great here.

but there we let there be light. There we go tell us about this. So This was Um, started as a a Kickstarter project so funded uh over the Internet by people who were interested in creating a or being part of the creation of it and a couple of guys Tito and Josh in San Francisco came up with the design and uh, it's actually a really lovely design. So originally when they started it, we thought it was going to be a project we'd have to solder a lot.

but they've actually gotten into a point where it's now pretty much a kit set. So Pinoo Case: um, you know PC Power supply PC Cooling system One board that they've created themselves. um, there's actually an Arduino Uno sitting underneath it. Okay, Y and uh, what it does is basically uh, gets a program uh, loaded to it that has uh timing around Heating cooling Cycles take a sample of DNA put it into one of the little mini test tues here.

Okay, pop that in with a couple of enzymes in there, close it up and leave it running. might take an hour or so to run through, and uh, basically takes that DNA sample and magnifies it multiple times and uh, and then you can go and do further analysis on there. so you might do things like um, you know, maybe you're suspicious that your local uh fish shoers selling the fish that they claim they are. So let's take a sample of that fish and and go and see whether it really is that.

um, we might be worried about a a product we're we're eating that might be genetically modified so we could find out using this machine, but you would have to have some sort of reference to some sort of reference like a golden reference to compare it to. Do you? Yeah, you do? That's right. And even so, this is like five. This was $512 They're now about $5.99 so you know re reasonably good price and uh, you know you can definitely have one in your own home or in your own hacker space.

The problem is that the reagents that are used to run run the Cycles are specific to the type of thing you're analyzing and they need to be kept perfectly. Frozen So you can't use a domestic freezer that that does the cooling, you know, antifreeze sort of cycle. So um, so after signing up for this I then decided that having one at the hacker space wasn't that practical. So I've actually donated it to CS Nice! So it's going into the secondary education program so kids will be able to use it Fant to learn about it.

So um, yeah. so it basically just Heats right? It's just heting and all. It does the controler very precisely. So P Yeah, okay, yep.

so it's a large where's the on the side there? Yeah, and they're heat pipes, Are they? Yes. So it's basically just a standard PC cooling type system that's been, uh, added to an extended with um, you know, couple of custom aluminium blocks and so on. The bit that took the longest to get right was how to get this lid assembly working. Originally there was thoughts about making this a mechanical Electro mechanical assembly, but now it's just a simple screw down mechanism that works pretty well.

So how long does it take to heat up and cool down the samples well? Depending on what you're sampling, you use different programs for that. Um, but doing a run? Uh, as we were, um, the very first I Me: They took about an hour to run. Um, can take longer than that. That's probably about the shortest.

I Guess that you you could run. Is that an LCD on the top? Yes, it is all right. and what is that? Just info? Yeah, basically just shows you where you know how many cycles has it done as it heating? Is it cooling? What's the temperature at the moment? And uh, yeah. so yeah.

very cool. So you can almost buy this as a kit. You can buy it as a kit. You can actually can actually b as a kit.

So this was one of the first Alphas So um, you know the starting crowd all got their Nam names. they're famous. There we go. Special thanks to the first DNA hackers.

y That's right. So um, and There are contributors to the project? Yeah, so this is pretty much the core team that made it all possible. Yep, excellent. and uh, and of course Tito and Josh the guys that came up with the design.

There you go. Fantastic. That's fairly new. Is it 2011? Yeah, yeah, right off the press.

So we built this about uh, a month or two ago and uh, and I've got another one that I still need to build up. So so we've got two of the first ones in Australia which is nice. Awesome. Yeah, how many of these have been built so far? Uh, I can't remember what the first slot was.

maybe about 200. but I think the orders are in way past that now. So wow, who would have thought there was demand for a DNA Well, some of the things that school kids are doing with these things are amazing. So I mean this is one piece in the chain of you know working with DNA but there's a competition that's run each year and I can't remember the name of it.

But basically school children are asked to to come up with a a modified organism that could do something useful in the world. So for example, they might do things like um, take a bacteria genetically modify it so that when it's in uh, solution and there's lid present, it will glow so that you could understand where the water is contaminated by dropping this bacteria and itow if school kids are doing of stuff correct. Totally. Chang Let me tell you.

Yep, the fun one that a lot of people do is glow in the dark yogurt, right? Yeah, pretty easy and common one to do so. Yeah, thank you very much. That's all right, that's awesome. There we go I think I read every single one of your books when I was in high school.

That's right. that's that's the very thing that you want. It's something simple that doesn't turn you off and that's exactly Now that's exactly I saying a great format he want to come between. no, no, we have to do it.

We are not worthy. No, be silly notth noty the and you can smell it I love the smell it good I assume it's ABS NOA oh pla Okay, all right. oh abss yeah, it' be toxic wouldn't it right? I'm here with Andy from The Hacker Space Melbourne Hacker Space Thanks for joining us and thanks for coming! No worries mate! It's been a big night tonight. Yeah, it's huge.

Big turnout out here. It's massive. We had to come out of here to get some decent audio. It's it's crazy.

There was about half a dozen projects goinging on the garage laser cutters, 3D printers and everyone's just going. It's crazy. When did you start it? Well, we started in early 2009, a couple of us um John O and others we've been talking about what would be great to have a shared workspace right? and uh, at the same time there's a wide magazine article talking about the hacker space movement around the world that is emerging and it seemed that at the same time the the Brisbane hacker space Sydney ort of just popped up like mushrooms roughly the same time. All right.

Okay and it's always been here in your garage. So far we we're well and trly outgrown it. Um, how many members? How many? uh well, it's it's hard to give a specific number we've got. There's over 300 on on our email list.

There's about um, 30 to 40 people who who Rock up, um throughout the year and On Any Given night we can have 20 or more people in the garage as we have tonight. Yeah, um. Any any issues with setting up a hacker space? would? if somebody wants to set one up, what are the pitfalls? What do you? Insurance Do you have to worry about anything? Noise? Neighbors I Think all. I Think all of those things.

Um I think uh, think about hacker spaces. They have similarities so you go to hackers spaces. and they have design patterns or recipes for hacker spaces. Some hints about what to do and what to avoid.

Okay, uh and uh. but Beach Hacker Space also has its own culture I think depending upon the right I'm sure core members, the projects they um, they like to work on and the and the actual physical space they have right? So uh I think uh. the main thing is to build up a core of of people who can um, help who can help newcomers, who can, uh, who can lead projects and can welcome um beginners I think um, the the the Hacker Space culture and particularly things around. The Arduino Community or the 3D printing Community is as much about sharing knowledge and and and trying new things and and bringing people into the fold.

Yeah, so do you have is it mainly oldtimers here or do you get a bunch of beginners turning up? what's what's the ratio of beginners to quite a range? Um, we've had from um, parents, our fathers with their with um their 13-year-old Sons oh they they they turn up kids, fathers turn up with their kids. That's great I love that that's great and and we do have a lot of beards grhe heads uh, people who retired or um who been in the industry for for decades and and they're very often Keen to pass their experience on. and so it's It's like it's closing of the loop. From people who who have loved electronics and and hacking all their life to passing On to the Next Generation Fant So there's a core group that turn up pretty much every week and and then there's stragglers.

Just your regular drop-ins just turn up occasionally. And yeah, we as a group we focused very much on trying to have good group projects. So we start off with um, a CNC Mill, which been developed over a couple years by by a number of people leading that project. We've had a number of arduo projects Uh, each year we, uh, we're part of um, the LCA Mini in terms of deciding what the project is helping John Ox put that together.

Okay, um, and we've competed in the great Global Hacker Space Challenge. Um, and uh. So early on we did a lot of Uino work and uh, and then more recently there's been a lot a lot of interest in 3D Printing, right? Yeah, that's been a big boom too. There's almost hacker spaces starting up just around 3D Printing projects like things around Quadcopters, um Mills um.

Rocketry? um, Avionics? um vehicle Telemetry a few different type of robotic projects um, and and and and so you hacker space can form around those sort of group projects and then people come along with their individual projects um to either share what they're doing. oh or to get help or something like that. Yeah, so we had a a young fell just joined recently. He had an idea around controlling show hot water temperature with Um with presets and so he he he's come along and he's the 3D printing guys have uh have designed and printed gears for him to to drive the the and he he's done his.

he's got some I Gu, some help with the uh electronics and he's done his own board and so that's a great. Another great example. Excellent! So what's the future? You got to move you're looking. Oh yeah you're trying to get a new space cuz this is you know this is crazy.

You can't continue in the garages. Yeah well tell want number of people ask say how's my family cope with this exactly and uh and my family's been very forg I guess very very tolerant. But also if someone said to you like every week people are going to come around to garage and they're going to work on laser cutters and you're going to fly rockets and helicopters and Bu robots and and stuff that just and up DNA Replicating machine Go! That'd be awesome if people did that and that's what happens. And for I've got a young daughter and she comes and she's more of an artistic B and she can see people doing doing 3D modeling and using connects for scanning and so I think it's a wonderful for kids to see what's absolutely yeah.

you don't need permission from the government or some industry body to go and create something. just do it yourself. so you're looking in Melbourne C like actually nearer to Melbourne We'd like to be uh along a train line. um a lot of our members use public transport.

Um so it's that tradeoff in a Melbourne Sydney expensive cities to be close Um and yet um, uh And also we we don't want to disenfranchise any members because of Um fees are too high. so uh, we spoken with Um councils government other uh, not for-profit groups. Um, there's a group called the Uh ATA who have an electric vehicle group know the At. Yeah, so we like to um, potentially share a space with them because they they work on electric vehicles right? Um and that's other thing we typically like to work on.

Projects have some Community good. So things that are useful for education like our open Open Lab project and doing a based Um science project for for high schools um or or we're talking towards the end of the year. the Um I think it's called it Assist which is technology for for assisting disabled people. Okay, excellent.

Uh, all things like looking at, uh, looking at how to save energy. So so I think uh, doing community minded projects and having members where you're not you're not charging Fortune Fac facilities for you means that we we need to find assistance either through government grants. Going to say, what about sponsors? Are you actively trying to find sponsors? or is it well, uh, we probably should more than we are what we doing the moment we want to make sure we've got I think if you look like a bunch of guys women in a garage, um, it'ss difficult for government to take you as seriously is if you've got a decent location. so we've um so well it's a chicken and egg kind of thing isn't it? So jeez so uh but but U but many it depends where you are different different hacker spaces of um some been fortunate in terms of being getting uh great great Paorn rent locations, others members have just banded together and just really um stretched themselves financially and and taking taking a bit of risk.

yeah um but the main thing for us is that it's it needs to be fun people coming on, learning and we're not taking on the stress of um of of commercial rent or other things that um cause us to lose focus on what what we here to do which is to enjoy ourselves right? But are there any like is it a formal organization? Is it a league? formal legal organiz? oh it is. So so we have a an elected committee. um we're a not for-profit organization. We have bank accounts.

um so when it comes to we'll be able to to take out a lease um insurance. So we at um there's the men shed Association in Australia and they they've been around for decades and they and they they they've got their insurance s out so we asked them they showed us what insurance policies so um so you when you've got um uh SS and drills and other things yeah, we we take we take safety very seriously. Uh, but it's stage someone may accidentally pick up the wrong end of a soldering line something like that. And and so you need to have all those things in place.

unfortunately. Yeah, you've got to have the insurance just to cover yourself when you got Joe public coming along pretty much. but this isn't an open Hacker space really, is it. You can't just wander in off the street cuz it's not the the address isn't published, Is it? Yes, Yeah, You can wander in off the street if you found us, if if you found us.

but you've got to find the address. It's not openly published, obviously so well simply cuz um, we wouldn't be. We would do doing any of our members or our souls any favors if just so. Um, so yeah.

So if people find us, we welcome them and say please join us and help us look for location but we're not making it. We're not advertising saying come one come all right good. Excellent. So it's looking good.

Yeah, thanks that well thanks for excellent. Thank you very much. All right we have Luke and we've got a laser cutter. This is our our laser cutter.

It's a CNC laser cutter with a 50 W carbon dioxide laser and it cuts stuff and stuff on fire. Awesome! And it's It's quite big, It's quite sizable. Yeah, it's like it's quite a roomy one right? And how did you score this? Um, yeah. the Panc I'm not the best person to answer that.

Actually, it just magically appear. Yeah, it was. It was acquired at minimal cost from some people who were getting rid of it. Excellent.

Here's a little: I don't know if you can focus on that. It's a little piece of acrylic that's been cut up. Anyway, that's pretty cool. I Like it.

and what's the maximum size can do. Um, probably like you know, several hundred mm, 700 mm? Yeah, yeah. we certainly can. There we go.

So that is a 50 W laser, right? Oh, it's in the back and it. How does it? It has a Wow. It's a water cooled laser tube. Yep, mirrors.

Oh, there's there's a mirrors. one of the mirror holders there, and there's a mirror inside that. another one there. y another one there.

Oh okay, right. So the arms move it around right and it's And then the mirrors just turn the beam at right angles. got it and refocus it down through through down down into there. So there's another mirror inside the head's.

a mirror there. and there's a lens at the bottom there. Everywhere you see three of those adjustments, you know there's a mirror there. Okay, got it.

Awesome! What an awesome bit of kit for. And that's the uh, some of the acrylic we are plan to cut up right? eventually. I Think it is going to D everywhere. unfortunately.

what are we putting? It's a Mickey how did you go that so fast I had to ask Already got there we go. that's the one made one we made previously. awesome. It's going to go as a H but it's not saying yes what thez size is I know what's going resolution and you can get it down to than that's get the sh the difference.

This is all right. We got a secret project here. well not not too secret but basically to basically use an Arduino Telemetry board that has GPS and uh barometer. um has a zigby for radio coms and uh right up so that basically hooks up to this box which is the Petry on the motorbike.

right? Ah there we go. So you can just do things like you can uh eventually show you like show you throttle throttle position. yep once like the bike up and uh should get upm that's cable I Think close the thrt and this is his little project. Is it? This is Mark um Mark baby right? What's going on here? So does he sell this commercially? Yeah, it's a commercial.

This this is a commercial product. I've been using the hack All Right Throttle so so we've got a GPS on the back but there by the looks of it GPS unit there's a Micro SD for storage there's a barometer. There's a 3axis accelerometer. uh temperature.

Um, there's a zigby radio. Yep. and uh. also the serial connection to it back to a mobile phone which then gives gives me net access so you can do that in real time.

Yep, ex. excellent. and you incorporate sensors into your bodysuit as well. We've gradually working wearable stuff, so um, so the idea would be have um Bend sensors um, gcop exom on on on your jacket.

So right, and you're actually riding. So as you're going around the circuit, you can actually see the well. You probably actually want to do that while you're writing, probably want to concentrate on what you're doing. butly but certainly other people can look at the real other other people in the pits, look at the real time analysis, actually look at the real time data and you can look at you look yourself later so you can see you know what, what, what GE you're in, what how fast you're going, what RPMs were and also what you how you position on the bike.

This, of course stuff that professionals have had for many years. But what's interesting is as a hobbyist to have access to information, just see what you're doing in terms you know, breaking and controlling the bike. Fantastic. And you can hack all that using an Arduino pretty much certainly can.

It's just a great Workhorse oh sorry 4 mm hole which is 5748 which is is good. We've got John from Fre Tronics here o and he's got some stuff for me. Apparently this is an old one. What do we got? Oh Mark Just pull this one out of the archive.

This is a 2010 which is the first Arduino compatible board that we worked on. So the name 2010 is Um is from the year it was made because it was based on the Deil Nerva design which is 2009 in Italian So it's very much like a Deila nerve, but it's got um, all the parts pushed down down to make some prototyping area. You got a prototyping area on the bottom. fixed the stupid USB connector made a mini instead of a yep move LEDs out onto the edge so you can see them when there's a shield on top.

y pretty basic yeah some general basically stuff like that and there we go Tada fre Tronics board. Check them out fre Tronics.com Yep, that's it. y that's the one. Yeah the cool thing about this is the prototyping area on there means that you can use this as a starting point for a project, but then add your own part so you can do like a little single board.

custom solution really easily. Excellent. I Like it. So that's an old one that's ancient.

That's an old one. Is it still available? Been sued by 11? What else do we have in here? That one is an 11. That's the that's the latest brand SP and new one? y right. What are the differences? The difference is that instead of having the Ftdi chip for the USB to serial converter, it has an 82 doesn't which allows you to do like a USB host.

So it also allows much faster uploads and things like that. So this is like the the tweaked, updated version of the design, but functionally, it's pretty much the same. So this works like an UNO. It's um y.

so when you're programming in the Arduino ID, just select Uno as a Target Ford and that works perfectly. Y and I Love it. Designed in Australia people new Beauty All right. Ah, now this one is one that Mark has been working just recently.

It's called the USB Droid right? Very similar. It's compatible with Arduino but it has onard USB host got it. so you can use this y for connecting to an Android tablet or something like that. Yep, and it's got a Micro SD card.

I See, yeah! Um, so the idea is that with this it's compatible with the Android open Accessory development kit y so you can use it for making Android accessories fantastic. There you go if you're playing around with Androids, check it out fre Tronics USB Droid Beautiful. All right in that is more of the same. Let's see what else Mark has packed I'll get back to those things a minute.

Oh, these are interesting. This is um, one of the first things we did. Actually, it's a um a network Shield so it's a an Ethernet shield. The difference with this, unlike a lot of the Ethernet Shields that came before, is that we pushed all the parts up to the end.

Once again, the idea is that you shouldn't have to add a prototyping shield on top right and we add a Power Over Ethernet support and the way this is set up. It has a little header on here, so if you want to do really cheapy DIY Um, power over Ethern all you do is cut into the cables, send like 9 volts or something down the spare wires, you put these headers in place, and the Uino just Powers up straight off the land cable. Yep, so you can uh Power stuff you know, 100 100 m away down down the EET cable. But the thing is that there are really two ways of doing power overing it.

One is the really cheapy DIY approach. the other is official power over Ethernet yes, which I've yeah, I've worked on those Yeah, 48 Vols 48 Vols with the signaling mechanism and everything. y So the idea is that that is a module that you can so you take the jumpers off and you solder that in place and it gives you full 82.3 AF Support: You can run that commercial injector Freetronics Power Over Over Ethernet Ethernet adapter. Tada So that means trying to focus on my head folks.

Sorry. There you go Anyway, it's very cool. Check it out. So that gives you the flexibility of doing the really cheap approach or compatibility with full commercial that you can just plug it on there.

but then that right? Does it go Upside? No. Go that way all the way down. Um, yeah. and there are little standoffs that give it mechanical support up towards this end as well.

Got it? So you just put it down f it on and then off and you can still plug a shield on top. Yeah, you can still stack another thing on top. Um, it takes up a little bit of space. but um, yep.

there we go. It plugs onto the the Ethernet board. Yeah, you got too many. This is ridiculous lot.

All right. Um, yeah. Okay, you can grab one out of the box, pull out of the okay so you can find a um nether T That would be cool. This is a receiver, so it's basically a very simple 433 MHz receiver module.

Yep, so I can just do um O or that sort of thing um. encoding and it's useful for picking up signals from domestic appliances like um. Weather stations often transmit on 433 MHz Um, car alarms, garage remote, door controls, home automation system. a whole bunch of stuff.

Lots of stuff. Okay, so originally I did this for intercepting signals from a weather station, right? and Mark did all the work, decoding the protocol and got that sorted out so we can record data off a really cheap weather station. And yep, data, log it as well as lots of other yeah. um, I've also used these with legal things you could use it for I'm sure.

y so yeah. I've used this to receive um data from a rocket Telemetry system as well. So little class: SE rocket with a tiny transmitter in it? Yep, and um, pull down some data. What have you got there? No, no.

must be in one of the other boxes. Maybe in this box? What have we got? Um, uh yes. That's The Ether 10 That's The Ether 10 Is that your latest? uh, not quite the latest. Not quite the latest.

That's the Fre Tronics Ether 10 Nice board. Check it out. Yep. so it's an Arduino with buil-in ethernet? Yep, with power over ethernet support.

once again. so the idea is it's a single board. You plug it onto the end of a land cable. Powers Up and Away you go.

Awesome! So it's great for home automation projects and things like that. Yeah, the hard part is getting power to stuff. it's it's I know power of the ethernet's great I Love it. Yeah, so I've got a bunch of these things buried in the walls of my house, under the floor, and in the ceiling.

All sorts of things. In fact, light switches in my house have one of these behind the mounted in the wall. So what happens is that the light switch just has a control surface on it. Yep, which um sends a signal to The Ether 10 which then connects to a web service.

So I've got a Linux box running in the house. a Linux box drawing in what 100 WTS to turn your light. It's a solid state little yeah, it's a like a router running eded Run 10 it's only a few Watts it's it's basically the same thing as like a network router. Okay, I've got a on it.

you're off the hook. Thanks. Yeah, so that's the same thing. but out of the box, out of the box, there we go.

There's the E the 10. Tada It's not the best light in here. sorry, but there you go. Go check it out fre Tronics.com Another one we've just done.

This is a prototyping shield with terminals screw terminals down the edge. so this is called the teral Shield The idea is that that makes it really easy to connect external cables to your project. Yep, piece of cake. Yeah, I like it.

We also have prototyping Shields without that. Yeah. I've seen the wing shield on the wing Shields of that. Yep.

and I Think that might be most of what we have here. Oh, there's a kit version of an Arduino called a kitten. A kit. A kit.

Oh, a kit version of the 10 kit. 10. There you go. Build it yourself if you can.

They're really simple actually. we um, earlier this year we had a bunch of these at the Arduo Minon in Brisbane Y and got about 50 or 60 people assembling these and most of them were software hackers who'd never done any hardware at all. So we actually taught them how to solder and they assembled these in the space of about an hour and a half and powered them up and got them all running. They all worked.

I Was going to say they all worked. it was fantastic and that is an LCD Shield So it's 16x two y character LCD with some input buttons for navigation or menu or whatever. Okay, yep. exell.

Mark very cleverly mounted the LCD from behind the PCB Yep, bit of lateral thinking so it comes up I've done that before. It works quite well. So there you go. It's a if you're looking for a novel way to Mount Your LCD on your board you can actually do a cutout in it and uh, Mount the module on the back and have it protrude through the front like that and uh, they've got extended looks like nice brass.

um are they brass? Yeah, brass. um actually. T buttons actuator tactile buttons very nice. So excellent.

The LCD Shield um, it's not too exciting, but this is a prototyping Shield so that's just y basic area for Um for development. This one is a kit which is an RFID lock Shield so it interfaces with Nfid R module. It's got a relay for driving an output like a solenoid door lock. Yep, Um, so these things are pretty cool.

I actually have an RFID chip implanted in my arm and um I can use? Seriously? Yeah, seriously. and does it show us it's just in here? Hang on folks. Hang on. Jonathan Oxa has and he is fully chipped.

He is, uh, living the it's just in here. you've got. You can't see anything because it's been there, can't see. Been there about 4 years now so the scar is all long gone.

and yeah, come on, you got to be having me on. No, no, no, you seriously got an RFID chip in your arm? Yeah, there's plenty of footage on online of it being used I was on some. There you go. He's been the government ATT tracking him.

He's beautiful. Yeah, I just Ed an animal implanter. but yeah with this basically it means I can walk up to my door, wave my arm near it and the door unlocks. So insane.

That's dedication. All right. Not give me a uh a uh passcode any day. A good old retinal scan.

Yeah right. retinal scan? Yeah, that'll do it. I Don't want the government tracking me? No No. I'd have to put my tin foil hat on.

Excellent! thanks John And that's fre Tronics See you Thanks He.
