security and say this very quickly because of a lot of a lot and we have strongly possibly into the risky alive demos which say
and sometimes by the teacher I gave a talk at the wrong about 1 experiences with . com and and on talk about must cover the station I have now left teachers work for the rest require Foundation which is the charity side of the organization which carrier mentioned in keynote this morning so you have before we go on
to the weather station and 1 of the things that we're really passionate about and I'm passionate cities that will work with students that projects they work we should have a purpose and we want talk about this this morning in little purpose is really important if the examples that we work and we give kids to work with all of links and engineered then that is the the part that that's the value in the case of products with that's really important here 3 projects have got going on not mentioned after applying here although loosely connected with space and a surprising events with was going on in and the year we're sending some other points based kids occurred in Python code to work on those rows replies to the Carribean run in space from UK kids the reason the pictures that is this picture and there was pointing to a loss with with a raspberry calling on the helium balloon um acts of node motion while to this was that it reached no sure about this to sell at 2 kilometers had this picture is actually fight what 1 would favor 1 there is actually a picture 3 1 4 which is and so we doing this with some kids as well and teachers and and showing kids how we can use programming science engineering technology to do do cool stuff this middle picture this is the the weather station which we'll talk about 2nd and over here it's amazing pictures go cropped you can just about say here and we've got green house next to a plant then to talk around spoke briefly about this this is the greenhouse project that allows kids to write code to monitor their health while flattened ladies the health of reflects the health of the plot same projects with purpose really important at and when I
was just leaving teaching I was given 1 approach to and that's quite different this a lot bigger and it's been re-engineered slightly and we these these pose a given to schools and we can then we got set up with the kids we talked about how when data is collected and we still will still say that the very last day on the last thing I did lot and the caretaker drilling holes in the wall feeding table there so I could leave this weather station in life and so this is a real quick look around the harbor Europe got here and say this is what we call around reply hats and it sits on top of the right of reply connects with the mounting holes and it connects well with the cheaper had a lot sits on top of the page of gold in the case of animals come close to later on and and then those 2 parts the form 2 separate parts of the weather stations you got main board which about holding him in this case and this is the beginning of the course content and they also got a smaller case which contains an air quality sensors so this 1 you remove all the of about things that was open to the air to the actin circulate the separate those 2 out of the communiqué arise when so you get the main parts the weather stations and we connect that to the weather station with a serious offenses so we've got this is standard can a week with this story you take 1 this is what they're wearing the same kid by stock and that tubers Simple Avr engaged which operates with the old sort figures and old total digital switches just count the number of the can figure langauge so they can be add to the amount of rainfall we've got these 2 sentences so this 1 is an animal element that so that we can measure wind speeds and this 1 is a well-defined so we can measure wind direction OK these just connect while erasable paid
nobody knew what was it again and and so will always have insensitive also go on the
air quality sense so we've got grounds temperature that we can have very in the grounds we can measure the temperature of the soil um and so the the whole it is sensible if you've also got to because such as part this is loadings were also got uh a backup
battery the real-time clock this poses runs replied and deploy it somewhere and it sits there and it doesn't take long between the track and when you get
when when when these are then available you can just follow a dollar sets up deployed having loading data that's that's that's a great big take you know you've got a lovely weather stations set kids to interrogate data but what's even better is if you can show the kids how it works so I'll come back to the
project list of our resources so what we're doing is we're building up a selection of resources which are going to show kids how to go through building or a weather station from scratch and the first one reading digital sensors that's fairly straightforward if you've got a range image and that's things you can detect the number of pulses but that sense down a lot because a simple text if you know
how much water is each bucket according to take that work and how much water was flowing through that so the simple but of and that work the animal that set is similar in so got a little is a little magnets and as the animal just spins around the
magnet traceability can and then you have to do some math so we interested in very somatic interface and schemes of work where the students have to work out the circumference describe described by the monitor can use
that to work out the distance traveled is at times they won't have the wind speed they even if the guy that sort related to the surface and very thorough you even think just for what's called animal what effect the energy lost by the wind pushing the the very at the onset and we got a series of schemes of where the where 7 . 1 as well so the panel data that is a bit harder but we're hoping to get kids and the readings in the analog sensors as well as presenting like data if the line demo works later on we've got really simple point gain give me that we just not up for demonstration and that she so you can see what the senses are reading and and then into we have the data loading takes a number of sensors collecting all this information how we the Allegheny use text files was lots of inherent issues with that already use and very little of the value get and the idea is a database which I have to do that we should have to build a web site of interface so it is the graph of of the state of and then the big data are combined to bring the bread policy and the big database is that we collecting data from all around the globe dangers giving available to schools so not only can access the data from their local weather stations but they can access the data from weather stations all around the globe collected by schoolchildren like that bring them into a tree global projects so how would do this shows the project is is bigger than the hardware is bigger than the resources a huge part say we produce a thousand of these texts and already that not we we're talking oversubscribed new most schools signed up the day we're going to school the 1st thousand and the going global part of with Oracle and Oracle involved in other aspects later as well so we introduce these resources have which share with people with with with schools so they can use them and the local school was that data more secret database which is then we periodically uploaded to a central oracle database which is going to be able to be accessible to you all schools participating and possibly be of so underdeveloped . 1 role in this apartment delivering in school where all being mainly over resources saves interview flavor of the and
resources so this is is helping to rest replying and this is a lot more resources like and this is not yet the public so but will be shortly so you with a little over view here of the resource it tells you what you will need now only very quickly the internet connections go right and so just talk about himself that of the form of Ivory quickly realize previous in distilled that's why had warm weather stations and a class of 20 kids I didn't to engage with this warm weather station would be difficult so this problems that know the 1st thing you can really easily for the 1st year of working here and if minds situation was to come back
but they're going to what you need and you can simulate and monitor the Netherlands at the they've needle responsible answer but there's lots of the cost of later on and you will be given that those bits but the of all that these and spinning around this switch view pair just to wise and together or a bottom of took the pi and the kids can where competition to see how fast they could simulate wind which is of society's long mashing buttons entirely on the fastest wins the bid committee wave velocity did have and then and then we got want the code was working they could come up and bring them prior gives the weather stations testing and then we have the water on the teacher's desk and that was that was dangerous but we know we tested various calibration to loads of cold solids and and and programming involved in and say that's part of time all exist about about the weather station set so the white I think community now longer fully and alive demos which uh could be insisted so we should say so you and I want to do as well maybe it is a technique is I might at this stage was something some setting of life from the floor to any questions that you might have cake and I can be knows what the setting up some about again is our so do you have any questions at all about the weather
stations always the setting and so on problem that is also thinking
right the and I guess 1 of the obvious questions is what is your ETA for so much of this additional care right so you have the this 2000 boards the reproducing they all and they always produced things frozen aware and so the project Korean involved in the resource generation and so the project of 1 my my primary focus and that I'm also working on a number of them and but also working more generally with the projects and where the conversation is nothing our aim is to get these into schools and into the early to late autumn this year um but was still waiting to have some these resources written working and and then beyond facts I believe and again this isn't sort of in concrete but I believe the idea is that these boards will eventually sales and other people can purchase them have those in their schools and just for left the going design hold various languages has an interest from some 3rd parties and some people as a group could endanger points I have here do like a bird boxes with cameras and things and what they want to do is they it integrates the weather station into their product so that as well as collecting data about wildlife there are also collecting data and about whether the the conditions in the climate at the same time so you've got that's a matter of what's happening with the wildlife and what's going on in the local environment develops the question just time roughly your yeah it was it roughly I think I think 6 months would be a fair estimate of the moment and for upon which I mentioned the beginning and which is also space project that's taking it a huge amount of time coverage fixed deadline which is and it is a launch a rocket launch with which we have to kind of fits in with that not way for us we are lost and the ESA and that did not only flexible on removing the source of Soyuz rocket for to go to entire lines so you and so yeah it's weird gonna small gene so it thing that we've we've got with us today myself carry and then that's searching was possibility falsity yeah that that thing and we're the ones writing resources were routing conferences like this where very small teams bear with this but I think 6 months will probably fair estimate so you've got aster part and a weather station are you to tell us what other magic pressure you have in the pipeline um if I knew I would probably about and so there are there are a number of things going on and so I mentioned infinite on multi-task over sorry I should have a degree more than that yeah in making expressing the city gives and gives me a way knight and savings encouraging in my city and the picture space was picture I showed you earlier on the bleeding we did last week we are working and teachers later this month to get them trained up on how to launch their own and when the balloon launch will apply attached so that they can and so they can take this that the other point in space and intend and capture data from up there so we had this really successful launch this week running out of of space here you sorry I'm probably think constantly trying to this wire to reach this laughter that angle and so yeah we did this launched with um in in in cambridge we had our little test launch delays in what we call for as 24 teachers coming to visit us there are good but this is this and we don't
teach them how to launch that I would have billions at the moment is that the return series something we're gonna take hopefully take 2 . this balloon launch is currently the software that runs the tracking is a well written in C so I sat down and try to get point kids to do so we program even and manipulate how it's working so what of other types of vector that C and on the condition Python book and so we use that to build a science and math and engineering the predictions all would be also From a teaching point of view is is I could expose the kids to the current it's working behind that I have some top-level libraries that just what is the basis the functionality this parameters you can change his ways you can commitment so if you're interested in the model that projects under the going over the original software mainly telling him he's a
little bit of Python but it just hasn't was going to go in the middle so you and if you're interested in the office and all and for which a some of now we got here say if we just go in and out of the terminal
window this is just a raspberry point definitive model because it's using a B plus and because the we don't need the power of the point you just sitting there looking like a and David system want this renders a really super original naming status just called thank you they obviously have so hopefully we should we should get here is the reply game interface
and we can see the local have current
weather conditions now I believe this setting which I might have to disable will give it go so the idea here is got this I'm going on I think because data looking about background yeah and the 10 something give me a 2nd so I have to tell you this a common job running in the background but I think I have to
close the come to think it's going to the 1st try again and a complicated that
light data working and you know you you plug in your idea about
widening the balanced to with taking this into the classroom is but this is not the only thing that I've had never written point software and all played in application and and they fuse together in a few hours that approach and with kids but be quite challenging thing so what you know I would really like from the everyone's interest in helping it is my so the framework here we we've got the basic elements and the kids just to manipulate properties have stop activity from from scratch but perhaps was implemented in pointing 0 which we had about this morning would be also and I want to say that this is 1 of the things that we've got working so this has been and sitting data loading and um and consider creating database and background has been running right dates of lower data that's and more we've got on there is still running we've got a website it's doing some
graphing and I was recently and is it really I was recently looking back of foster remote access to global markets school I recently logged into it help to dog I looked into it to have a look at what is doing is really interesting up until a few days ago there walls about 3 o'clock was noticeable data quality and have to a lot everyday noticeable did possibly consciousness would clock was a deep inequality I realized it was because it was only classroom all directly next to the coffee as 3 o'clock chronology to just want right going across all the exhaust fumes just kind of like like book to call the eQTL questions and every day was a spike in quality and the site and that is and this is still running but then we should gets yet so that was the point
where the domain and so I think we we should have the relief and we show how the graphs that which are working but the idea is that will work through kids and parents puts a graph data on so can we can plot so that the findings from the last few days because so that this is a partially successful demolition Bruton trade and yet so any any questions so I've got 5 minutes so that was I am I what I was
wondering about the east east screenplay and monitoring project was reading a little bit about it and I hope I don't think setting up where I do someone into would keep the distance where the stage might be too complex but the greenhouse looks good but I think it's different some projects in the UK the testing it and then how can you share any timeframe relates to the allele with which projects are being considered that the plant monitoring color-changing currently and it's a a small-scale project which is happening so how many would we produced it's a small sample for his mindset moment there there's there's there's Greenhouse's Learning exhibits so it's is part of uh so so yeah to move about 100 that we've produced for this this also exhibit project going on and and the creation of values is is mainly looking at my parents house and she can engage the adults and children together on the same project so you and the procedures so the and students come together and to the workshop that look how to use taken home and that would like to get and then lessons from that and that made some point down the line it informs some of the schemes of work by connecting that's probably that online with you and you of the IEEE anything these the solicitation project immediately to the complex for children but what to h do you think they had could be a happy involve the discussion of the bright objects are very very strong and regarding the different schemes of work and the wizard of proposing and the 1st thing of what I've written by these entities 3 children say UK that is an 11 to 14 years old OK and they've done some very basic point that when appointing programs consist of 12 lines of Python because all they're doing it is very important and they are assessments patterns and they just sit there and count and lead how many how many events there or and adjust every every few seconds I just presented with the current speed is so you and that's certainly very accessible the and the graphical user interface the things I think that's probably would we're looking up the 2nd regressor 16 onwards the world is a world where we've got the idea which was proposed and so was a talking there were 2 but his computing its in theory possible to interact with this weather station using other languages such to scratch so I am 1 idea that we've currently got is to develop may be a way of and displaying some that when the data using scratch so young children they should be reading so that data displaying it in a more graphical kind of engaging and 1 and even we know which really young children they could discover that it is raining therefore on have occurring travel to introduce a really simple stuff and but also as well once you've got all this data is being collected that would be the point at which the has promised schools can get involved because you've got this states we can start talking about what is where how do we look at what does it mean how we we produce and they can start using them
