  1. A very sad day indeed, he was a true giant in his field and an inspiration, RIP Sir Patrick.
  2. You just need to short the polyfuse, don't need a resistor.
  3. Seems I was entirely wrong on the path you actually have to install libv4lconvert0 and libv4l-0 (if you 'sudo apt-get install webcam' it will install both as dependencies automatically). you can then find the modules in /usr/lib/arm-linu-gnueabihf/libv4l/. look at this page for instructions: http://linuxtv.org/downloads/v4l-dvb-apis/libv4l.html#id3156114 in the 'v4l1compat.so wrapper library' section at the bottom of the page.
  4. There is something in the v4l drivers that allows you to use a 'compat' module as a wrapper, (I think you use ld or something to load it before running the actual app. that you want to use.) I think there are probably plenty of cameras that the pi will work with, we just haven't tested them and we desperately want the spc900nc to work. I think one of the issues for the pi is that it's using a kernel that is 'too new' for the pwc drivers, the drivers were better it would appear around 2.6.xx rather than 3.x.x. I think if enough of us turn up on the raspberry pi forums at the same time asking q
  5. Hi Gina, that's a lovely set of nested if's you've got there, have you ever considered using a 'switch/case' statement instead?
  6. I think the key point here is that this is a development platform and it doesn't work for the spc cameras (which really are old in the context of things) whereas it does work for the qhy5, so it's not all bad!!
  7. It's funny that whilst the licenses for arm11xx chips were originally released in 2002, arm11xx chips have featured heavily in the mobile market, having more recently been in iphone 3g for instance. So whilst it's 10 years old, it's a well trodden road, the main distro support doesn't matter, they've got/will get it into the mainline kernel and have their own distribution, it was doing pretty well on just squeeze, now in the space of a few months they've put raspbian on there (converted to run faster with vfp. Getting driver fixes and updates isn't an issue but I will concede that some issue
  8. Nice to see someone has tried this, I have been working on trying to get openPHD working with the philips webcams (I've got code that allows us to do long exposure already) but unfortunately right now, there is a bug in the pi usb driver that stops the philips from working at all. I had expected to look at this soon, so I'm guessing that the qhy behaves vastly differently to the philips webcam as it seems the qhy5 just works. Regards, Reggie.
  9. My son's pi has now turned up, along with my Dads The mod my pi cases are probably about the best looking out there (Imho) . There seem to be quite a lot of issues with USB devices and powering the pi. You really must make sure that you power the pi with a decent 5v supply!! 700ma phone chargers don't really quite cut the mustard, as they have a tendency to drop voltage whenever they approach full current draw. Cruddy usb cables can cause issues too, somewhere in the order of 0.5v voltage drop with the usb cables and my usb hib being plugged in I found the samsung galaxy microusb cables
  10. try virtualbox instead? That will allow you to install XP in a virtual machine. It's free, it doesn't particularly care what host OS you're using
  11. if you can get the case open and see what major chips are on the board, I'll have look around the net and see if I can find datasheets, you never know, there might be a long exposure mod to be done....
  12. nightvision, that's why i suggested aerogel, I know the slabs of the stuff are insanely expensive but perhaps a small amount of the aerogel pellets or some of the cloth cut so that all of the heat generated by the unit is encouraged away from the sensor, towards 1 face that is left un-insulated.
  13. Finally got my hands on a raspberry pi today, all worked quite well straight out of the box. Grabbed a random 4GB microSD card, put it in an adapter, used the windows image writer software and put raspbian on the card with it, plugged in usb keyboard, mouse, internet cable and hdmi, powered the pi up, booted to the console, put username and password in, typed 'startx' hit enter, a few moments later and I'm at the desktop Opened a console and pinged the bbc, job done Very simple to use, very happy with my pi so far.
  14. Gina, have you sorted out the icing problem yet? I was wondering when I saw yesyes gui for his TECs and saw that he had ambient dewpoint listed, it occurred to me that once you hit that, then you will have more of a chance of moisture being attracted to the sensor? I'm wondering what other ways you could mitigate that apart from sealing the unit? I guess airflow across the sensor is a bit of a no no? Fatwoul, have you looked at xbox360/ps3 custom cooling solutions? They're designed to fit inside the meagre cases of ps3/360s might be an avenue to explore?
  15. Kind of, you can actually make your own www.aerogel.org has instructions.I was really looking at the aerogel blanket for you guys, which is considerably cheaper than the blocks, the small pellets are cheaper than the blocks too!
