 Buongiorno, Alessandro Volpato. Ciao, ok, iniziamo. E' quando parli di il Roccure Rainbow Building & Open Source Petrometer. Sì, è un progetto. Ok. Perfetto per lui. Grazie. Oggi sono Alessandro Volpato. Io sono un innovatore biologico. E ho base in Berlin, in Germania. E sto lavorando sui progetti e software open in order a democratizzare la research. Quindi tutti possono fare research, biologica research a casa e rispondere a questioni di protezione e di questioni semplici di bio e di questioni ambientali. E è possibile fare con un po' di petrometer o altro equipamento. Sì, abbiamo esperimentato con l'equipmento e abbiamo incrementato la comunità di persone che stanno facendo questo. E ora siamo arrivati a un punto in cui abbiamo bisogno un platform in cui potremmo share questa data e share i progetti e capire come cooperare. Perché c'è un po' di persone svolte e si fa creare. Quindi, qual'è la motivazione? Perché ho preso questo progetto che è il Rocchio Rainbow? È chiamato Rocchio Rainbow perché è come se analizziamo i rainbows come vedremo più tardi. Quindi, abbiamo creato questo platform per standardizzare i risultati che le persone potrebbero ottenere a casa. E questo è il prototipo, un prototipo lavorativo di questa tecnologia. È l'open drop da Gaudilabs e è completamente l'open source. Puoi trovare l'open source da Gaudilabs, ovviamente, e è anche su sale. E su questa superficie, puoi muovere le droppolette da cambiare i fieldi elettrici sulle strade di droppolette. Però, diciamo, è un'altra storia. A top di questo, puoi creare un spectrometer per aggiungere un'analisi biochemicale. Quindi, vogliamo integrare questo modulo di spectrometer e abbiamo avuto a creare un spectrometer e in realtà un spectrometer può lavorare solo e può lavorare con questo dispositivo e può essere creato in tutto il mondo e può essere l'open source. Quindi è più, non è una cosa, ma è un platform di spectrometer perché la gente può cooperare. Non importa quali dispositivi puoi usare per farlo lavorare, ma tutti puoi farlo con le stesse procedenze. Alla fine, puoi share le procedenze e i risultati. È una cosa bella che sta succedendo nel futuro. Che è un spectrofotometri? Quindi è bella. È solo tirare la luce e spettare la luce con un prismo e così puoi vedere il tutto il rambolo. E poi analizziamo questo rambolo. Come analizziamo? Prendiamo quali colori e quali intensità. Questo è usato per... Quali colori? È usato per ottenere le moleculi, per vedere quali moleculi c'è e la luce intensità la luce assorbita da questo chemical e puoi quantificare quanto il chemicali c'è nel tuo semplice. Quindi è bello. Un esempio di questo è... Oh, è chiuscita. Sì. Non funziona più. Quindi... Ho bisogno di avvenire qui. Sorry. Sì, sono qui ora. No input? No input. Well, I will tell you about the project. So it's a... in time that it's gonna work again. This is a great project because it started one year ago at the tech fest in Munich, in Germany. And... and then had a lot of... we participated in a lot of events to develop this technology on and on. And it came to a point that we made it work, actually. Help. So, we made it work and that's the result of this making it work. For example, this is the spectrum of a compact fluorescent light lamp that is a mercury lamp. And we can see that the splitted beam of this lamp takes this form, has this color inside. So some bands in blue, some bands in green and in the red one. And by taking this picture simply the picture on the computer like the JPEG file and analyzing the intensity of the pixels you can actually get the spectra. And that's a... that's a nanometric precision. It's a device that can be used in a normal biology lab. So, of course, the hardware has to be improved because it's wood actually, but it's working. It's possible to really have this quality. So, how do you build it then? Okay, you have to build a device that is worse in a lab in order to go for it. So, I got inspired by already existing spectrometers that were available. Yesterday there was the Spectral, the Public Lab paper foldable spectrometer. It was downstairs and we saw it working. That was a project that was run during the British petroleum oil spill in the Gulf of Mexico where the people of Public Lab trained all the citizens, to use a spectrometer to go and take sample of water and to call the authorities to clean up the oil in the water. So, it was great. And Gaudilabs is a developer in Switzerland and we are working with him for several projects. And that's another type of spectrophotometer. And this is how does it look like. So, it's exposed even downstairs you can come and see how does it work. It's perfect because you can disassemble it. It's really in five minutes you have assembled it when you have all the pieces. And it's perfect to explain the concept. So, you see the light coming from here and it works exactly like like this. The same principle, we have it here. We have here a diffracting grid that acts like a prism and here there is a webcam. And so you can get your data directly into your computer, into your laptop. So, it's clip-clap. You don't even have Sainz or Inge. You don't even need to go through Arduino. It's usable from everybody. So, people, biologists that works in a lab doesn't have a clue about software and hardware. And you have to deliver something that works. Yes, that's the problem I'm not working this open source thing because when you deliver it you have to deliver to somebody who has no clue about what's behind it. So, they don't know hardware, they don't know software, they just know the chemicals they put it in and it works. I'm a biologist, I did it like this for years and now I had to build it on my own and go through the code, through the hardware because there was no no spectrometer that was designed for this purpose. The design is really important when you do something on open source because otherwise it will be wasted. Nobody will use it and it's done for nothing. So, you have to deliver like a finished product. And what's the application? That's the more interesting part of it because you actually can do a lot. So, science is a really powerful tool for understanding what's around our health and and everything. So, we have here three examples I will bring you. The risk of artificial light so I will go deeper in this topic later like with all these energy saving lamps we forgot to check if they are compatible with our skin and our circadian rhythm and we will speak about that later. We can do chemistry and food analysis so measure the nutrients in our food how nutrients is our food and if it's polluted and it's spring to a point that somebody is doing soil and water analysis there is an Indian guy in Copenhagen that is working on top of that and at some point we come all together in the same project because as long it's open source it's worse to use it. There are places where there is the solution the problem, the issues and we bring together issues and solutions and it's fantastic. So, what's about the health? How did you come here? So, that was a study from the EU committee that was about how the artificial light affect us they were issued about the UV light UV beam that this light emits and they so they began a study for this reason and at the very end they came out with the point that we are normally exposed to UV light so from the sun and that's the main source and the effect on the skin and on the eyes were not that in relation to the sun it was negligible so you don't get skin cancer from the light inside but from the sun so it's not negligible ok, I will but it will disrupt your circadian rate that came out so you won't be able to sleep that well if you are exposed to this light before sleeping and overall they are deep deepening it and it's more the blue light that is giving issue so the LEDs the old LEDs, these white the school white LEDs are giving issues and we are switching they are switching now to warm white that is lacking of blue and it's more healthy it's for the mood, yes the mood goes bad and then you go depressed and whatever so by chemistry and pigment analysis that's what we did in the Berlin Science Act A and we had a basic work in spectro-autometer and you already see that the sunlight has a complete spectrum the suffering has enhanced yellow and red so that's the other colors are absorbed so what we see it's what comes through and what we don't see it's what's absorbed by this pigment so chlorophyll you see a lot of green and low red low red and blue so it's it works and that was a basic version now the one that is downstairs is improved and we will do biochemistry happening I have extracted from penis some pigments and later we will check if it works and the precision here is the how do you setup how do you make the setup for the extraction it's acetone, eye hole basically jars and for you can even isolate the pigments by paper chromatography you use this blotting paper that is the paper that kids use for cleaning the ink and let's say you dip it into the into the solvent and the solvent runs up above the paper bringing with it the whole pigments and depending on the chemical physical properties of the pigments they get separated then you cut it, you cut the paper when you have isolated you resuppend them and you can analyze them and it's something great and what's coming next so we have yes we are going on with the analysis a colleague of mine, Cat Austin managed to make a protocol for the extraction of lycopene in tomato that is the red and polyphenols from grapes and yes you can do actually extraction then you can do analysis whatever you want like in a chemistry or bio lab and that's it's a really powerful tool then you can do yes we are going to take contact for the soil and water analysis we have already contacts for doing a project about endocrinal disruption that is done by the alliance in green that is a group of people who are doing endocrinal disruption that is when chemicals that are in the environment where we live in so it's not just the environment water or food but it's even the object that we use so bottles plastics environment and they can interfere with your hormonal status and yes do bad stuff to your body so get you sick and moreover the most difficult thing and the reason because I'm here is to establish collaboration between groups in different part of the world so I'm based in Berlin we are collaborating strongly with a group in Heidelberg, south of Germany then with this girl who is in Boston and another guy who is in San Francisco and yes Rana maybe Singapore as well yeah I can hear Singapore the plan is to leave here the spectrometer to somebody who wants to there was some girls who were interested in do-it-yourself biology so I'm to open a space or to some kind of hacker space and to run something together and yes we have an hackpad and we if you want to follow me on twitter I already I just set it up but I will dispatch the news on this on twitter and the hackpad is used for the uploaded documentation but we are as well in the Hacterian network so it's for this reason we need a platform for do-it-yourself science where we can upload and upload the status of a project open the results and having everything comparable and yes downstairs there is everything to see if you are curious to see it so the real spectrometer it was halogen lamp plus the dieterian lamp for the UV so to get a continuum spectrum in a do-it-yourself environment it's harder because with a halogen lamp you're lacking the blue but you can use tungsten lamps they are they work pretty well they have a continuum sorry we are running out of time actually ok can I answer? we have some questions sorry it's just quick question analysis of dust is a major problem here if you don't want to even shut in a room like this so if you leave everything open you have fresh air but you invite a lot of dust and it contains particles and all kinds of stuff that so you can see from the dust what kind of wave spectrum you can divide the contents in the dust there's one thing the European and you are in Europe so wine is everywhere have you done a reverse in Europe? of? wine wine so actually you write the species of grapes not according to later ok not even talking about the content of alcohol and all that but it's talking about the pollutants in the grapes so like virgin point so extra virgin sorry ok wine is only matters I'm coming to answer to you personally
