IR or Time-lapse? Questo e’ il problema.

Ho comprato una webcam x 8 euro, ieri. dovevo aprirla x levarne il filtro IR, ma alla fine non ce l’ho fatta. Me la son portata appresso a lavoro, ed ecco che mi vien in mente un’altra cosa. xke’ non usarla x fare un time-lapse movie della vista dalla finestra, con l’albero che lentamente riprende vita con l’arrivo della primavera?

edit: ci provo, con l’aiuto dell’unico sw free che mi consente di prender meno di un fps – HSSVSS.

x ora una semplice ripresa a 1 frame x minuto del panorama fuori dall’ufficio. domattina se il risultato e’ decente, vediamo se si puo’ fare qualcosa di piu’ lungo.

e’ un peccato che la qualita’ della webcam sia cosi’ bassa:

magari se questo va a buon fine prendo una webcam decente o trovo un modo di usare la vecchia digicam.

EDIT: in verita’ la cam va piu’ che bene, solo che era messa di default ad una risoluzione schifosa e la interpolava via sw, il che la rendeva estremamente lenta. Ora fila che e’ una meraviglia. Wow!!! solo 8 EUR x l’equivalente di una webcam hercules con ottica in vetro (che di euro ne vien 50).

Infrared photography

I recently heard on the naked science podcast that pointing a remote control to my camera phone I could see it flashing, because the sensitivity of the CCD inside extends to the near-IR.

It wrks! And it gave me a terrible case of cognitive dissonance to look at the remote through the screen, then with the naked eye, then with the screen again and so on. I just could not believe it, PhD in physical chemistry notwithstanding my mind was not prepared to accept it.

Anyway, the cool factor of the thing pushed me to show it to all my friends (real, as virtual) and to look on the i.net for more info about it, and possibly for how-to on how to build a proper IR-camera.

I discovered that few of them IR-capable cameras are sold, mostly for forensic use, possibly because you can see through clothes. In general, CCD are screened against IR not for this reason, but because the color yield is altered by the IR noise.

Anyway, there are plenty of descriptions on line and may be this evening I’ll buy a 9.99 EUR webcam to open it and remove the IR filter. I already have a ten diode IR lamp at home, so may be it’ll be enough to get nice pictures of my house in human-eye darkness.

More to follow!

Wind

I’ve taken a LOT of wind last weekend in Oostende, going around to take this pictures. The least you can do is to have a look at them.

Do you believe that forks are evolved from spoons?

In fact, from recent genetic studies it is clear how the cutlery center of biodiversity is China, where an endemic population of primordial chopsticks still lives. From these, or a similar concestor, the ancestor of knives emerged, with a successive speciation into steak, fish and butter knives. More recently, a second clade gave birth to spoons and forks, with both adapting to different gastronomic niches and accordingly varying in size.

Loosing my Italian

It’s finally happening. Mentre il mio amico Paolo festeggia l’avvento del suo inglese nativo, cioe’ del momento in cui parla direttamente in questa lingua invece che dover tradurre back and forth dall’italiano, io mi rendo conto del contrario. Quando leggo in Italiano, mi suona strano, e cerco continuamente di ritradurlo in inglese, come a correggere gli errori di un incompetente (ma inesistente) doppiatore.

Arrgh!!!

LolCats!!!

I discovered yesterday this fantastic internet phenomenon of taking pictures of animals and adding funny caption to them, most often in a degenerate, gangster-rapper-like form of English language.

Here’s one example:

It has been hard to get back to work after seeing the first few, yesterday.
In between the piccies I also found a funny movie posted on youtube:

So go here for moar funny pictures.

How much the (OECD) world invests in R&D

It’s in this nice graph, from the latest edition of Nature. Sad to see Italy lagging behind, I did not expect the 4% that Sweden pulls but at least 2%, come on!!!

The latest analysis from the US National Science Board confirms that Israel leads the world in its economic devotion to research and development (R&D).
Its civilian R&D spending in 2005 accounted for 4.71% of gross domestic product (GDP), more than twice the average among members of the Organisation for Economic Co-operation and Development (OECD).
Although US R&D investment was the world’s largest ( $340 billion ) and in 2004, it was more than that of the rest of the G7 nations combined, the report offers some evidence of a slight decline in its standing.
Its 2.57% share of GDP is comfortably above the OECD average of 2.25%, but both South Korea and Switzerland have leapfrogged ahead of the United States by this measure since the board’s previous report in 2006.
Germany could now be poised to do the same.
Most countries are investing more in R&D than they were, says Arden Bement, director of the National Science Foundation, which published the report.
For example, although China ranks 23rd in GDP share ( just 1.34% ) it has pulled ahead to third in total R&D investment with an estimated $115 billion in 2005.

I am most surprised at the incredible figure for Israel expenditure: almost 5% of the GDP in R&D. and I thought they had to spend all of their GDP in weapons to keep their many enemies at bay…

Octopus loves Mr Potato

Here’s a new one. I have always been trying to convince people that octopuses are very advanced creatures in terms of ‘braininess’. That it really isn’t a good thing to fish them out of the water and kill them bashing them on a rock, or even worse biting their heads while still alive, as my gilrfriend saw with horror in a beach in Sardinia (no picture of the event, unfortunately).

And now, I discover they can get emotionally attached to puppets, just like a six-year old boy. In the picture, an octopus who was given a Mr Potato toy some months ago, and has been defending it since then. Differently from me, the octopus must have liked the new Transformers movie, since the puppet is in fact OptiMash Prime, Mr Potato version of the Autobot’s chief in command. Who would have thought that an 18-wheeler would need protection from a Kraken?

A New Digital Camera?

After only a few months with the DMC TZ-3? Yes.

It’s not that I don’t like it, it’s a great camera, its seamless 28-280mm zoom is fantastic, but… there is always a but with me… the noise introduced by the chip messes up everything, I feel like my old nikopn gets better pictures after all, plus in darkness without a viewfinder the large LCD screen is a pain to use. I am pondering now on a big step, that is, to get a real SLR body with a good lens to start with.

Nikon, since I still love the little coolpix, plus the fact that my father has one so we could share lenses and stuff.

Probably the d40, or the d40x if I can cough up the cash.

The only thing I don’t understand is whether the lenses works as in 35mm film cameras, or the 18-55mm is really more of a 24-70mm. Anyone who can tell me more?

Another one bites the dust…

Another friend leaves “old” Europe to fly away, to the West Coast nonetheless!

She’s one of the smartest and prettiest girls around. And she makes good coffee too! (the link is broken. one day may be they will put it)

Francesca, good luck with your big American adventure!
