i'm honest elected to the new president which amount left spain in october yet has death the director entry mccabe has resigned just weeks before he was due to retire he's been repeatedly criticized by the u.s. president for alleged political bias keep it here revel geek's is next. they're the children of jailed chinese criminals with nowhere else to go one beijing shelter is giving them a home when he speaks the children growing up with their parents behind bars at this time on al jazeera digital technology conference and it's interesting easement and even longer. even a.t.g. billions of calculations you know. it seems to be stuffed into mention. in which everything in our lives to train and train. and intended. that is convenient for profit and surveillance he only needs.

to look at leasing their skill challenge tech jobs. and enable a different technology. one rep people not a part of. the. home that has not. the problem with this but it seems that sometimes i don't really adjust for the local time zone but i just got a random times on which is half way between when i was in the area. honestly that. it was very very young goes off because of.

that there. is sort of ok i'm going to do this too but ok. good luck with the. you guys really he crossed that maybe you know this. really will all. live on the number of poor people you know that matthew's reality is we know nothing you won't get. to be friends we started peace protocol without who you know which does especially the ox's to being able to field we didn't tommies we don't really having to go to school five years degree the atomics. i'm going to show you how to melt and

electronic sounds that basically first thing you need and it's an arduino microcontroller you need the arduino code which essentially it's a computer inside one single chip doesn't have a screen doesn't have much but it can build things with some so it's. one of the early communities that john told all musicians illegal sorts of musical interfaces for computers then there was a lot of interactive use the lucian's of the baltics. people sort of use of the unit to build the first open source drill. then it was the first open source three d. printer. people said to go and see oh look at this project sports great i like you what do you use all used up to you know what he's up to you know. you guys will contest in north from tustin nor you have what looks like a whole bunch of little tiny boards there mostly arduino microcontrollers so what arduino is is

a open source hardware that you can use to write software that interacts with the real world when you're holding your hand as an arduino mega it's the it's of the big one right now that i have this little chips that are called microcontroller. the thing is that if you become a computer you will find for example in the micro. ways over simple terrible stuff so study using that we realized that a lot of software and hardware was a baby with an open source license we want the something that you could build yourself if you wanted to it would be to make it cheap even eat the cost like a pizza so i stuff to develop what became of the wheel. what happened is that at the same time that we start to become a little bit where norm the maker movement started to. come down to zero and whatever the military. know how to make. bases that make a fair shed and we are writing to me though this is making the robot which is that

kind of symbol of maker faire not even the kind of foreigner to have it so big. as. the maker faire is an event that was started about ten years ago as a way to get the makers to get together and show what they were doing showing projects. what are you working on and this is a good way to i thought it was all right. liquid identify yes but why not a feel for wall street on a b o on a quality i only count on your device. that's pretty cool that project is quite interesting they could make that souls mold or you can put it in. a regular glossary you know you can use a form a lot of different that's an interesting project so basically we made

a bunch of the any good lot of these one is like the kids can change the drawing on the fly and you get effectively for a very nice course at that by the whole feel of the you can if you're on it the bigger picture from the pound knight and send it over here and wait. then i'm with painted on the. like you know only engineer for children grandma do that if the film school. was. maybe. the software. gets downloaded but once again.

what's happening right now is very simple. technology is pervading every aspect of that life. at the moment that he's this perception that the can all just something you buy what's on the shelf but you know way if you look at the supermarket and it would only be pre-cooked food and you wouldn't be able to buy some fresh produce to cook then you would find that the world was not a free world you know you would have why you would have to get canned soup only when in technology in a way you know you go to a shop and yes twenty five different types of tablets but effective they're all doing the same thing so what if you decide that you want to do a different topic though you don't want to do something else then you need to be able to sit down and think about it and maybe build a different one. i

think. you what is this is in for a sensor infrared sensor though this wire isn't. in my undergraduate education that i i learned like a postman then i figured out that doing things with commercial is not fun actually i got the idea of maker when they had english imperiling that was no more that. right now than we made the woman in china but the interesting. ok. i got. that was. a big party and there is one requirement you have to have that object you never blame the path for that act like so yesterday for about none yet i think over something else when i stopped off as a kid i was very interested in understanding go to school one christmas my parents

gave me as a present this kid was a kid to learn about electronics he could build a circuit so if you make seven you would stick the stage to put together the disk you plug a nine volt battery you put your phone and and suddenly you hear voices you're like wow i just be the radio so those are very important for me because you want to stand that the chronology is not as complicated as you think it is. nice collar bone. but this is where you are in europe do we know. let's say i want to build something that tells me when i got too much sun time you know i'm at the seaside and i have to be careful otherwise i beg i could take a bus is a little component because there might be this other component. which is a light sensor.

and then you put in. every. take over. so we said to people who want to build a porch the first thing you do open one of our examples so you just have to copy. in a different way i don't know why. you start to create the connection between what you see on the screen what's happening in the real world.

but the only way to have one hundred eighty s. and build stuff. that project that it takes like a stupid project comes from another project or somebody and they become that became that. impression that these two other people made back.

to dr particular to see people that he's actually step number five of twenty five and at the end of the line there may be a very relevant thing that comes out of that. hydrogen explosion has occurred at unit three of the hamster can put the human daiichi nuclear plant. in japanese authorities have ordered people within a twelve mile radius of the plant to remain inside more than one hundred eighty thousand people have been evacuated from the area. this is to be hoped if you feel this is to be hoped though. people who they used to live here they cannot come back here anymore because all of. new korea

occident that it was very unclear about the the information. radiation contamination was we can the see if we can this made it we can offer you anything i didn't seeing the government is hiding anything i saw the government just cannot do cannot control the situation very well because it was very quite chaotic. i just sold if i have this energy i ship you know something something something for others. i miss hunt that's how i start in building sift guessed. the outside these high right now the whole point seems seven inside

a bottle legacy about. her experience i don't see this number so. the box on the other there and the receiver that's sitting here is one of our third generation a guy and he says it has a geiger counter and a g.p.s. receiver and it was in every five seconds location. time and now though they are a nation of balls everywhere i go and it's creating a data point every five seconds along this road which will upload our maps and be able to see the radiation levels around us and there was no question that we would use any but we know from the very first. when the government tried to put out the information they basically said it was no problem in fukushima and there clearly was people didn't know what to believe.

that we have here and we don't work that there's older country from the girder countered and communicates with the p.c. to get through the radiation level. through to know that we were desperate to get the data on the maps we had to act quickly if we got seventy five percent reliable data right away that was way better than one hundred percent reliable data two years too late and. we got something working drop a few more. big i. read approved we have some strong rains outside. what are we measuring here right now is to stay brood thirty six now so it has to match thirty six so we see very consistent error reducing numbers coming. out of this these meetings with the plane we've got to do you know the comics for a certain amount of cars and they want to be able to wake up one day and build a network called network connected to geiger counters in the space of these

a community needed then and they were ready. so. the cost to go through different time and not the did which we call these radiation droids because it kind of looks like r two d two so from star wars and these are these are the ones that started appearing but a year after jack all around fukushima this is was you know this is a japan this is the new one. where the problem is is that the government doesn't say anything about them we found them by just coming across them so somebody putting in sensors there's no signs on who owns them or who installed them or how they work or where you can find the data online alians could have dropped this here. or is it one point zero. sorry six

but anyway one point zero micro see about prove every compared to four years ago that number has been decreased about that's because half life of cesium one city one thirty four one hundred seventy s. . the health effects of the stress of the incentives for katrina are having a very sizeable impact on the people up there you know it doesn't matter if the fear you have is based on something real and rational or irrational it's still a stress in people have a right to be told what's going on. i just said guess i'm thinking this is like. a dog in my pockets and didn't. looks like it. needs to. stay.

in but. it was my grampa thought of an idea to haul the cook on a day this sort of our being out there are so many more that's not good money month they need. some nice going to the mall was in the soup it was nice to meet you here on long cause i still have to hold on. please honey do you get that little monthly. that might. think they're going to got. mad at me they're sort of. the middle of the middle i look at you know look at it by the skin of the moment many and i'm on the. this i would consider this number two point one point one five point one eight to

be in the reading for this position. this is you know since they did a suzy did then they had to the mother didn't discover more on the second i know the much greek. debt halt. you want to talk about a bit of this and the mcconnell had limited debt. but not that it's the last one must talk to them but i do you. so you could look at the cut up. at the cinema you gotta get it more as you would i go see it than one enough acoustically not that. i get an amazing feeling when i come across these kind of persons.

this is something that nobody could have and. when you make something they can appreciate you don't think oh yeah one day somebody will probably use it to crowdsource radiation. but the fact that you've created tools that enable people to do that gives you hope on the fact that there will be other situations where we can build something knowledge which is independently created and will help us in other situations like this. there is no safe level of radiation more radiation you get the more risk you have of it causing some kind of disease. people in korea or new hamas or those places and if the radiation were to stay stable rest of life would probably increase their lifetime rate of cancer by half a percent doesn't sound like a lot when half a percent of one hundred thousand people get cancer what's that five hundred people

so from an individual risk point of view it might be manageable from france society point of view it's serious. but then if i'm going to think about us going i think. of it like. safe cast is deploying a new network of sensors in the occasions so we're going to put sensors that are instead of being on a car they're going to be on a building and they'll measure twenty four hours a day. some people say it's. their radiation it's gone already and they don't want to talk about it anymore and they should learn more about the specific information and using the impending data in its own data are no they're they're. not that one.

i don't know it's not that i know. thats it. it's on. its i don't know i don't consider it has hit it on the level of you know toaster the space shuttle it's a lot closer to a toaster and one sensor you know provide some data but it's going to be the network and then the string of data that comes from this and other ones that's going to have a have a big picture so you know it's one small piece of a very big network. the most recent reading is twenty c.p.m. seven minutes ago. we started from almost nothing to barely workable system in a week and within a month we had something that was pretty good within three months we had something that was world class and within a year we were the largest open data database on radiation information anywhere.

because the community now is not just that some of the people to realize that he's the one i'm on to be me so they're trying to kind of cash into this thing but they don't understand that by doing this they might make some money now but then they would the community which is your blood is your you know what keeps you up. there were different moments that i could have given up but i believe you can build the business makes you more money than you would ever need in your life and yet you create something which is a lasting value for many more. i'm going to fight the ego but the body into saying i want to work with my friends who believe in what i do. every allies that i spent

the last ten years basically almost like. putting money into a lot of bank accounts that are not made of money that are made of reputation that are made of respect that are made of. and now that these things happening to me i'm basically going out and everybody's basically giving me back all the love i give them with interest. i don't want to live in a world where everything around me is designed in california and made in china by somebody just make stuff because otherwise they will drive the choices we make where they will drive their way we will be creating the only way to be subversive you know nowadays is to be able to control the technology in a way you can propose an alternative. i also like the spirit that because you're makers like you are nothing about making mistakes you know lays good out that it's progress that's how you keep going keep

going keep going. we never know when the next one happens if that happens anywhere else you know what all of these people can help write of it we know how to do. well as i learned to read so that i could read every american. tax returns to activism with a new mission i said ok i'm going to feel like all right build software for social . digital dissidents within the technological for market rates it gets occurred medications made in their field from the captain part of the
