Re: RaspberryPi Camera for Astrophotography

Careful jamesh, you might start getting lots of pester posts from people asking you to make the camera detect Dark Energy or Neutrinos... Be awsome if we could make a pi + camera act as a black hole detector 8-) . I know jamesh is snowed under by the day job and would like some of us to take up the...

Re: Working Fisheye Lens?

The problem I see is that everything (except the bottom) outside the original field of view is very bad quality. Is the lens seated perpendicular to the camera board?

Re: Case

prototype_complete_IMG_1372.JPG I have used a modmypi case and modded it (well what else is it for?) I bought a small tripod mount and a 5CM flex cable. The cooling holes in the base of the modmypi case are used to secure the tripod mount (yes I will add new cooling later 8-) ) There is no 4th bolt...

Re: New features for raspistill command

Manual exposure and White Balance I'll let this port remain as an example of a NON FEATURE REQUEST post (which would normally be deleted) - since it just repeats the last feature request. If you want to discuss ONE particular feature, then a new thread is the best place. Otherwise this thread will ...

Re: New features for raspistill command

[quote="poing"] Manual exposure and White Balance I saw some talk about this earlier where I got the impression it's either not possible or not high on the list. It is very important though, a. for people who know what they're doing with stills and video b. for people that want to use the camera for...

Re: microSD card holder request or bust!

Also...it's a lot harder to drop, and lose, a full size SD card. Depends on the environment. I went on a driving holiday recently, the spring eject on my laptop launched an SD card into the bowels of the dashboard when I shoved it into the glove-box. Never to be seen again. :( Yes I have determined...

Re: microSD card holder request or bust!

peepo, I have had the same problem. I purchased a micro SD adapter. Yes: the micro SD cards are a little fiddly to remove, slightly easier to replace as the adapter has a spring action so you know when it is seated. Yes, the micro SD card does then foul the bottom of the case. A small file, knife, o...

Re: Backing up: definitive answers

Having lost data from the 'last hour or so' when an SD card went sick on me (more than once!) I have several scripts which back up data to the NAS box. Every hour I dump the content of my development box to the NAS using zip and scp. All data I collect as well as the live environment from several ra...

Re: Anyone who ordered from RS get their camera yet?

On a serious note, please would somebody from the Raspberry Pi Foundation with business links to RS ask them why the delay and why there has been poor expectation management. If they did not have any to sell, then why offer them. I am sure that a lot (well some) of the frustration expressed in the f...

But so far, I've received nothing at all from RS - not even an email acknowledging the order, let alone a despatch email or the actual camera....

Re: OK01 LED blinks 3 times

Somehow the name of the start.elf file became corrupted

alvinAvR

Just happened to me, I did a firmware upgrade and it crashed with three blinks on reboot. Maybe there is a bad filename in the update? Had you just done a FW update?

Re: kernel patch for Dallas 1-wire interface

have you blogged how you went about modifying the kernel to get over the 10 sensor kernel limit, or any notes on what to do? Hi Parkview No, this was just tested using OWFS to see if OWFS could see all the sensors on a breadboard at the end of a long bit of cat 5 E, it could until I doubled the len...

Re: kernel patch for Dallas 1-wire interface

I am using DS18B20 sensors with an I2C to 1-Wire bridge (the 2482-100). I am using the sensors in passive mode and ran into unreliable readings problem when I added another sensor. Having thought about the wiring and voltage / capacitance related issues and perused the data sheet for 2482 I conclude...

Re: Order Model A, get a Model B

replace the 3.3V linear regulator with an efficient switch-mode supply to see how low I can get the power drain on the model A. Great idea, glad you got your model A, my RMA has been collected but did not supply the replacement, so I am still waiting :cry: I would be very interested in the results ...

The only problem was that the box contained a Raspberry Pi complete with Ethernet chip and connector and a double USB socket. Clearly ...
