Do it yourself weather forecast and environment monitoring

meteo DIY

Paolo Bonelli, a member of the group in Trasformatorio 2014 and a atmosphere physic is since sometime developing in Milan a project called “CoScienza Ambientale”.
the aim of the project is to put research and develop tools for DIY weather monitoring and forecast and to check air and water quality. The project aims to create tools that range from the barometer to the geiger counter with simple arduino based projects.
But not only. Aimed to develop also scientific and experimental attitudes in kids the project is12037994_890664484333329_5593345883808586961_n now extending into basic meteorology and other types of instruments. Last incarnation is a workshop were the task is to realise weather forecasts and realise instruments to do so.

Winter Activities along the Sicilian network

Attivita’ Invernali

Prima a novembre a Palermo, presso Dimora Oz, adesso al BOCS di Bagheria. Il primo Worshop, introduzione all’analisi e alla progettazione di installazioni multimediali tenuto da Federico Bonelli. Il secondo tenuto da Gabriele ‘Asbesto Molesto’ Zaverio di “elettronica di base”, in cui partendo dal recupero di componenti si e’ arrivati a affrontare le basi dell’elettronica. Una attivita’ comune con lo stesso filo conduttore, concepita come operazione di bella divulgazione e facilitata dal trasformatorio. E tutto esaurito! Arte, tecnica, scienza, storia, attivismo, tutto finalmente dato per scontato, superato dalla voglia di imparare e dalla pratica di vita comune. Grazie anche alla sapiente regia di propaganda fatta dagli amici della Dimora OZ, del BOCS di Bagheria e alla storia cucinata dal Presidio Sucusclan che ci ha sfamati e nutriti. Organizzeremo presto altri incontri, il ferro (del saldatore) e’ caldo e le mani fremono. Pure-data, free software, radio a galena, electro-waste riciclabile, fare, costruire, pensare, esibire, condividere. Riprenderemo, ripeteremo, alzeremo il tiro inviteremo altri docenti, faremo formazione e azione. Informale e fattiva. Riproporremo anche in altri posti il bel lavoro di introduzione fatto veramente per tutti. A tutti gli studenti, ognuno a modo suo ricco di cose sapute e curiosita’ stimolanti un grazie dai docenti, per aver imparato.

Winter Activities

In november first, in Palermo at Dimora Oz, then in Bagheria, at the BOCS. Two introductory workshops facilitate by Trasformatorio. First one, an introduction to analysis and project of media rich and interactive installations, by Federico Bonelli, the next by Gabriele Asbesto Zaverio, basic electronics, were starting from the recovery of components from e-waste students were lead tolearn the basics of electronics. An activity sold out and conceived following a common approach “trasformatorio style”. Art, technic, science, history, hack-tivism, all finally given for granted, because our wish of learning and practice of common life is more important. Thanks to a great propaganda and support from Dimora oz and BOCS in the two occasions and to the cooking history of Sucus clan, that feed us and nourished as well. We are in the process of organising more meetings of this kind, the iron (of the soldering) is still hot and hands are trembling. Pure-data, free software, trench radio… to do, to think, make, show, share. We will take up, repeat, try more, invite other teachers, we will do formation and action. Informal and productive as well. This introductory work, though to be accessible to anyone will be repurposed, and our students have occasions to grow. To all students, each one of them rich of knowledge and curiosities, a thank you from us, cause you have learned.

Workshops

Next Trasformatorio offers a Workshop on Solar

Next Trasformatorio in Montalbano is going to offer a construction hands on get dirty workshop on DIY solar power. The project we are going to present is named ARETHA, that stands for – Air Exchange Thermal Assembly and is a project conceived by CISE2007, a group of makers in milan characterized by an enthusiastic passion for Do It Yourself and solid scientific and engineering background.
From 21 to 26 with a group of volunteers Paolo Bonelli will be busy in building a new version particularly optimized of the panel, and in documenting step by step the process.

We expect to have a solar powered thermal bath before the end of the week in Montalbano!

Solar Guitar

Di Daniele Pisasale

Amplificare un suono con l’energia catturata dal sole è suonare con un’altra energia.

Con gli ultimi sviluppi tecnologici di prodotti immessi nel mercato si possono realizzare ad oggi impianti stand-alone di piccola potenza, facilmente trasportabili e a basso costo, che permettono di usufruire di una fornitura di energia elettrica in qualunque posto ci si trovi, anche il più impensabile quale un bosco, una montagna o al mare.

Un sistema di questo tipo si compone generalmente di:

  • un generatore di corrente fotovoltaico (uno o più pannelli)
  • un regolatore di carica 
  • una batteria
  • un inverter

 

Nel mio caso ho utilizzato:

  • un singolo modulo fotovoltaico del tipo “grid connected” modello Conergy PowerPlus 225 Wp
  • un regolatore di carica Alpha elettronica RHN 10A/1
  • una comune batteria 12V 75 Ah
  • un micro inverter da 300 Wp

 

Funzionamento:

Il pannello fotovoltaico genera corrente in DC a 34 V, questa viene stabilizzata dal regolatore di carica che la porta allo stesso voltaggio della batteria che dovrà essere caricata (nel mio caso 12 V).

Generando una potenza di circa 225 Wp in una giornata soleggiata di aprile il pannello fotovoltaico è riuscito a caricare completamente la batteria in meno di 6 h.

A questo punto è bastato collegare l’inverter alla batteria per avere la disponibilità  di 300 Wp di potenza in AC. All’inverter ho collegato infine l’amplificatore della chitarra, un Laney da 50 Wp, e la mia semiacustica Ibanez artcore per riprodurre un suono realmente “solare”.

La batteria da 75 Ah completamente carica mi permetterebbe di suonare ininterrottamente con l’amplificatore al massimo volume per  più di 10 h  consecutive.

Solar module schemathics

Ai fini di essere il tutto anche usato in situazioni di mixed media oltre alla uscita 220V abbiamo scelto un inverter capace di fornire i 5V su presa USB (per il ricaricamento devices di ogni tipo). Inoltre con il regolatore DC 12 V, se ci sono dispositivi che funzionano in DC (ad esempio lampade a led) si possono collegare al regolatore.

Radio Astronomy in the castle

Gabriele “Asbesto” Zaverio and Aldo Cesar Faga’ installed a short wave radio station in the castle, for listening the 0-30 MHz band and to try occasional transmission with radio amateurs in the world (Asbesto is actually a radio amateur, with callname IW9HGS).

station

The basic idea was to change the orientation plane of antenna installation, from vertical to horizontal; basically

…the antenna we made is not a traditional shortwave radio amateur dipole antenna; we choosed to shape it differently, using the castle terrain, posing it in an horizontal plane. Our antenna have 5 long wires for the positive of the dipole, and 4 for the negative one, so in total we have 9 wires crossing the main castle court.

aldo

A 1:1 Balun (a balance unit made by a ferrite core and some wiring) is used to adapt the antenna impedance to 50 ohm required by our radio equipment (ICOM IC-720A rtx, YAESU FRG-7 Communication Receiver, and MFJ-945E mobile tuner). 

 

So the antenna now is able to receive can i take ativan with benadryl also signal directly from the space, as a sort of radio astronomic observatory; we know that many things can affect  the reception of signals (for example, Jovian emissions), but this is exactly what we are looking for.

antarotPutting cables on site was a challenge, due to strong winds that affected all the work, complicating everything and, literally, freezing us!

We also had bad times due to hardware problems in our radio equipment; an integrate circuit for the band switching was burned. Alberto Novello, incredibly, had the right chip to fix the problem! 🙂

Despite our weird choices, antenna seem surprisingly good both at receiving and transmitting on various frequencies.

We also set up an internet live stream, so now you can also listen what is receive by our station at this url:

Due to shortwave characteristics, the best listenings starts at the afternoon / night. 

We’re also working on other kind of installations so… stay tuned! 😉
