to kind
think we do that and the I
think that if hello all and welcome the following session is about the blinking rockets the need to devise that some of you might already know it's a 100 per cent open-source do-it-yourself saluting kits that offers the best hands on experience for beginners of all ages overflowing with the I hear that sound was all about the journey in making the blinking rocket flight let's you some flowers from 4 overflowing with know how well I can voice so rating for the flights to appear and by rating for the slides to appear a warm welcome from my side as well I'm with the juices flow but we're going to use assess later on again so that's will spend some time reading for the slides to appear and also warm welcome to those who are in the streams of police I got 1 in that somebody is on the tram right now so they probably have good connectivity to what this talk as well so I you gonna walk with us for the journey of being a rocket which is this little thing that I have here on this band and when I talk talk you through various topics so we're gonna start
with our project because you wanna have golds before we start something just like with any part we have they're gone talk it through the so the hotter what we have on there the design considerations behind that and probably most interesting software running on this little device and after all the good talk you through how to the park ties do which assess Solomon kids because we know that there are plenty of ideas here in that room and if you want a dispute your own do justice ordering kids while you can there and probably a lot from what we've ran through and what you've learned and also what you can do right in the 1st place without actually failing 1 3 or 4 times so talking about
us this year on the left side as flow is about debt of 3 and a member of the and he is the guy behind the hackers based shop that's moment shop for various do-it-yourself kits you creative plenty of do-it-yourself kits in the past so he's like more experienced than I am and I would
see it at the time I do big data topics at night and once the sun sets while I'm treading do-it-yourself kits for kids so at this point
in time I want to thank all the contributors that helped us making this little thing possible so the big shot and thank you for your awesome guys the end you can give them a round of applause so let's sort of
particles if you see this little kids and you've probably seen it already today because I do I can't talk there plenty of human actors ordering this so we have a target audience so 1st of all if you create something you have to think about who uses it or see wall intentional years behind that so we have children youth and adults basically as audience and when they sort of this they're probably at home or in shops in schools universities what you the hacks basis while most of us here come from Eq spaces so that's kind of obvious
and we have some requirements derived by that 1st of all I hate it when I have to use this better program out to program my devices if I have something great I just assembled its and advantages assemble something to just program it that's awful and also I hate it when I have to buy something because of forgot to buy it like with a little you thing the party had to have this use b to serial converter and I almost never thought about that so that was kind of bad also given the tired audience children while they don't fear of smallpox but adults too so we try to choose bit parts and their you like a little small s d parts here and they can be picked to so we made the footprints a wider and bigger so that if you sort of them they will flow nicely and you cannot do it wrong with lead and who want to have key components so that if you buy kids do not have to spend too much money and ideally it should be free anyway because we do not care about your income and everything should be free but it comes to learning stuff also the most important aspect if you make something it should be wall useful in the 1st place it should be fine and also educational especially if you're targeting children they should learn something and with this kid that can learn how to solve the they will see that something in the digital world can be translated to the real world so that was on main aspect and this will kind of fun to have something that links name has nice little animations on there so based on these
considerations the blinking about that was born about 2 years ago and on the fun
side you see the by a pixel dogmatics display then the audio jack for uploading data and that's like 1 thing that addresses this no program are needed aspect because we wanted to have the ability to use your mobile basically to upload you text so animations to that little device so this is kind of special to that to of Sauron kit also are not interacting with something is kind of boring so we added little to push buttons that he can move between the animations and text that has scrolled through the display on the back we
have of course the coin cell that powers the whole device and it lasts about a day or 2 so don't worry about new batteries also we have little lady tiny microcontroller which was the cheapest microcontroller back in the day with that much pins to drive to display directly also we have storage with 64 K of storage available for your animations and that's roughly 2000 to 3 thousand characters of text and there can be a little hard to read on that little display so it should be sufficient for all time also some additional little SMT components well to sort everything on
the software side of things everything is open source are like this awesome hair of already mentioned we wanna make everything open source and when we talk about everything it's not 1st source code or the PCB layout we also made our documentation open source and license at the proper rate we made manual that's actually printed and handed been for every kid also source and not only the PDF and also the source files that you can assemble at 1 year old Naur remakes that's based on your needs the femur was written in modern C plus plus I don't think it matters too much actually but I think it's worth mentioning though also we have of that editor for putting little animations and text on this device so you can use it on any device but it your mobile phone on a computer everything with a rep rather and an audio while device is capable of programming the blink and it's written dollars could of course if the 2 that applications and the 1 initially created it use the Austin react fares framework because it won't make things than the easier the article itself is using square wave so little squares signals coming out your audio device and you have a particle using forward error correction so that if there is a mistake within the transmission it be fixed automatically so
after a while we traded a thousand rockets so thousands kids to be distributed among children youth and adults they were manufactured by a lot of volunteers in May 2 thousand 16 after roughly half a year of development time in our spare time it was initially funded by the C C I would not too few were who knows of the cosmic ruler initiative by this is see if you agree to hands but it's a it's like the whole crowd so if you don't know it out go ask a neighbor after this talk what this awesome initiative is so just found it to be part of these workshops taking place in the cosmos for the initiative it was packaged volunteers but the set at the effects based text-based if you got so it took like roughly a day for 10 people to assemble a thousand kids and it was distributed across all Europe for workshops and here are some impressions
of workshops taking place but they were also the kids have plenty of fun to assemble a bigger workers and in the moment this live the battery and then everything started to blink just just awesome to these sees faces and see all that enjoyment in their face but there was a big cats and
this is where I had a to flow because we learned a lot and he's going to tell us about what he's learned the method of this is on giving on the tree from on the order of the this so yes there was a little catch
and learned a lot so the 1st thing when I got my hands on the 1st big rocket kit and I realize it was a really good 1 and there was potential to make this bigger and is good at 2 more kids so that's the 1st
thing the 1st problem by the court me well so that's the use clear race surface the data on the normal think that for example that worked out just fine but the same
manufacturer for another notebook I didn't look at all as you can see here the data was totally distorted and cut process that go so transmission from the browser to the rocket work reliable
some common errors happened a hat at the signal will drift over time like you and 1st picture left you see the yellow curve and that's a signal that to get out of a sound card and the blue signal the blue group is what the computer would make of that and so far by the water 15 absurd stars of the on the Y axis and you see that this government the signals were not to process it just wouldn't work out of reliably and also on the right to see the the have with the 2 heavily distorted signal but why why is that happening
the of well the results of our moon device multiple different you have different vectors of some chips you have different sound cards and so the old do similar things but not exactly the very same thing and most of cards but TravelPost various if you make a clearer signal goes at this a sound cards cannot reliably it's of some of them most of them and also those arouse layers between the that browser and the actual sound card for example you generate a some of object in Internet browser and it's given to the hours a travel and that gives it doesn't have abstraction layer and that this the kernel in that centered over to the actual hardware and in order steps in between the signal can be modified and is modified especially at high the level of the signal is modified to deal with it sounds good to the UN year but it's not really meant to submit data
so when this vitamin cannot refer to a solution of this problem by introducing it is the analog digital converter fiction which means the sampled the signal a lot of some of the other sometimes and but it worked so much more reliable than the old lady of simply detecting the edges of this clear signal but still there were some issues that didn't work 100 per cent and you spend some more time in the majors problem and he came up with the solution
of frequency shift keying and that work really good frequency shift keying means that you can make an not scariest at days you can see that the form it's like doesn't go with but this but more it's more coffee cactus a can and that's a fun because usually due to provides a base and that kind of of flooded transmission worked out much more reliable and it's also much slower but that's OK they're talking about some seconds to transfer the data instead of some milliseconds so that's sort of acceptable if you plug it in to take you out of 2 seconds and then you have to animation rocket
this is fixed I started to take a look at the heart of the Warhol addicted could be improved and 1 thing that it found out during their trips was that the battery holder was not the best choice because people will put in the batteries in their was wasted were not intended
so this is what the original material look like and could at the battery like this which is
actually wrong it looks like but that's not because the part of it is banned under those it is utterly of wind
sorting its that happened a lot and in this way the rocket wouldn't work so time I got rid of the better in order and introduced this
1 and it has some benefits it's a little it's a little more expensive than the other 1 but still lights in from the top and there is just 1 of the 2 into 2 but with the wrong way and that doesn't happen too often but if the other battery holder diverse 8 possibilities to is that the battery and so that talk of to give a lot of problems coming yeah then have
the origin matrix models include it was also very cheap but I thought that if you make the kids that you would take around the Eckart should look nice it shouldn't be 10 cents cheaper but it's off to 2 and a little extra and have good looks so introduces new might make model that has career adults and diffuse lights and it just looks better and turning on a revised to PCB design a lot and the little just of the components to of only a penniless the sun for production which means that I took 1 rocket and put it on a panel at this so we have 14 rockets and you can fit this into a vacant place wishing to automatically produce the ports so why is that because people parade versions of of targeting different users the kitten I got that for the 1st time in a it was rather complex and you had to sort of deviance you and the promise of and then offering free different versions 1 way to sort all this stuff yourself for a element experienced users and belonging nobody prominent ensue is already in place for targeting kids and so I want version orders and the component already on the board and it just sort of glued to the 6 of raw components of of the chart it's very young people of what 1 might automate common which is 6 is old
so this is the version 2 was born that and you make its model dairy but real life and the components of more far away even though assigned to make easier disorder that's
the thing if you make can bond it's quite easy you make the sign you ordered from China Intertanko corpus and then you assemble it the created thousand of something you're running of arouse changes and problems so for
example and for the 1st production run there 2 kids that are made in 2016 and everything was done by hand so what about this programming last program picture with his rejection force sockets replaced microcontroller inside and have a little script that flashes to microphone of affection from there we can tell the kids means opening the socket into goods through closing socket at about 1000 times wanted to take you all of the roughly a day of just of removing the single-chip out of the packet putting it in closing religious pressing a button opening the lid ball moving everything out into little plastic bag and these were kind nasty because there were like salsa Ziploc bags and while they're hard to open so I spend roughly 8 hours flashing a thousand microcontrollers which was awful you leave me not time if you ever make a kid this is something you don't want to just slow down to it this has had the artist and socially the hat and that it is in the in the rights of components were putting labels so that it consists of the arms of sexual and so you and prominent and 8 different other components like resistors capacitors and diodes and if different values so what they did in the 1st lecture understood to get stickers slightly labels couple a component up and put them in the correct position on this t denotes and put them in the kid it parts thousand kids is a thousand cuts the nervous deserves a toast time's cutting parts you need a lot of people on lot of time or both under that take the while that roughly 10 people helping out thankfully otherwise I would spend like Rexall month doing it and they spend roughly a day with can people to create a thousand kids and that includes also like cutting down parts and people were really eager to help so I was really thankful but this wasn't feasible for the next token thousand kids absolutely not yeah it's it's not fun it's of the fun acuity rambling kits this part should be the the emissions
that's what do for so when I say kind of to go for the production of the kids the figures I should save time by using machines and you difficult electrodes probable for times more money and pre-programmed ensues you can pay a little extra of some sense and you get and with the program it's from the manufacturer like 10 or 15 cents something around that total evolved effort and I did lose color coding of s and the parts in the orchard layout you had to label it said 1 and then you put the part right there in your kids you have the parts to this leverage of there's no text that's the red part or a green part of a group part and a given card it says put the red part on 1 integral part error that took of a lot of time in ascending the kids and finally introduced a new package of light that comes in a plastic package and you can use for transportation and also during assembly from Terry handed so
yeah I mentioned rewards beforehand but I was faced the job of making thousand kids I told Steyr-Daimler-Puch people to cut this parts of myself and I should machine for that and that the Frederick will take over and that's what it can assure you should be doing where you see how
that goes out the company in the 1st 4 days yeah so I put a machine that's Africa the think yeah that's a heck
of a hint of the tube is sometimes builds I told Allen Texans assertion the mold Laurent the work before iterations so what it does is it cuts as he departs from the dream of owning it was a color-codes the parts by cutting them so there's a little and market and you can see here that puts a strip of color on the strip before cutting it up so I could just replaced that for each path so they're color-coded and I have 2 buttons were I can adjust harmony holes of on to move forward for covering it up because of some parts were found 3 pieces kit of others which is to go on and that cuts a lot faster passes through through the FastICA up deposit parts in our house which saved me days of work to make disk it's it's just to leave off differed it took me 4 iterations to get permission right the main point of is that sisters are a spare part that should be it must be replaceable you don't want to build a machine that has some kind of mechanic to cover parts it is not replaceable so on use don't mess continental is pretty printed designs to hold discuses in place and so you see here ball bearings from rollerblades that cut that push down discusses there's 1 part of college pockets as pocket is like with little view the post spikes and so that something I report in China for 15 dollars and that that that gets in there and that's used commercial precompressed machines to move forward the tape so procedure fabrication once had
all of these parts caught up th the firm which is fixed it is time to go to the polls and have the peace manufactured because I got to Panel solution earlier from China diameter the parts on their the middle video of how the process works it was really fun to be 0 and it was it was a very nice of them to watch orders your troubles to the work so the emotional little that were not for
years panels and this is when the full pace
supplied some of it is now on the pebbles and then they go into the pickup place machine because configured before and this is really comfort just other over real looks in real time it was quite fast cancer part adjusted to this position is adjustment because into the open the ones that make that comes out of that movement of ions it brings you just have to assemble the true or components of self and then you're done soul you're have
and what's called me by surprise was the cost structure to make this kid but did not expect but the cost of notes would produce some voters say now that we have assembly tooling and supply chain because of about all 50 per cent of lectures costs and 50 per cent is material so even if you use machines to make the kids it takes time and in this case it took more time than expected so on and Codd saying kids of my shop for 25 euros each do by basically 2 kids and 1 is given into a little box and if you make a workshop with kids the school where they don't pay for it wanted to get out of there and give it to the to the kids for free and move style of pictures of the water connect see what happens if automation so that is my part of the talk I will handle again this so I think we learned a valuable
lesson about the cost structure because that will affect all of you creating such deal like it's because the cost might not be obvious if you post through with shops and see that like your microcontroller cost less than low but then all the other costs can add up to well what we've seen there so that it can be surprising and you should be right that so we also the cells right now what's next and I had a look in the audience why was talking and I've seen plenty of being rockets so that's already good sign so what's next today near a
solid workshops for children here on the congress so if you're and not about the H R but if you're children go there have fun and get your big rocket there will be more workshops because the 1st kits were distributed well in 2016 and flow did create another thousand kids so they will be more to be distributed for those workshops but they will be you would hacked workshops in Austria next year so if you're from Austria living near by other than you might wanna consider going there or while if you're not medals of course but and so they on custom being rocket but even if you an adult that's not a problem because you could create a workshop in your community see if you like to have a nice big rock solar rocks don't hesitate to ask us that we have all the material required to create your own workshop we have guidance we have manuals of best practices so just ask us and we'll try our best to make your workshop a Success I'll see you as you already told us you can buy a kit in his shop and there's automatically 1 kid being donated to such a children workshop because we do believe that if the child does attend the workshops there should be no fee attached to that because all we monetary everybody equal and money should not be a thing there so if you buy 1 there Of course there it will go to our 1 true Rockchip for a kid so I think that's a good thing if you got some time to spare
and I think everybody does especially if you're in your local heck space you could plan a local workshop so please do so but if you let developers willing to spend some time to improve everything after well there's a GitHub repository with all the code in there are you can create a fork you could work on the issues to make everything even better I like for instance better support for animations or that editing tools or create a share button for sharing animations with friends or you could just spread the word but everything is open source so we want to encourage you guys to actually use what we've created to create your own stuff so please be welcome to do so this is user for making everything open source and you would kindly ask to do the same but with the rest of this is
the art-rock already up there follows a Q and a session right now if you wanna ask in German if you not so familiar with English don't worry we will translate everything to English 1st and then answer in English and there would be the you the translation angels translating into German on the right channel if wanna a contact us after the talk and there's an my address there is a traitor handle and there's also decked phone number it was 7 per cent in the at 5 of the SLAC at 5 in the point is come to this stage right after the talks so far we can have a chance and we can show you everything in detail and have you out something thank you very much and host with we have 4 microphones set up in this hall please come forward the questions and we also take questions from online anybody don't be shy no questions the noblest there the but there is this and just as we question do you also sell but kids on site yes I would actually be 2 on the kids are available in the hardware hacking error rate and with the bytes umbrella's auratus at PGA but then I have some you can just follow him after the session so again having is willing to give you 1 but more thank you as anybody else the whole thing it's not thank you very much overflow of link to the revival you have 300 what
thank you that the and the I I think about it because if the 2 by Cocke but

Abstract The Blinkenrocket is a DIY SMD Soldering Kit that was designed to teach different manufacturing and soldering skills. A lot of work on both Hardware and Software was done in CCC erfas namely shackspace, chaosdorf and metalab. The kit is used in workshops since 1.5 years at the chaos macht schule events and is very successful in its purpose. Creating this project was plenty of work and there is so much to show and tell around it, it will blow your mind.
