The 'Raspberry Pi' thread

[trackhappy]

Had a bit of a scare earlier, thinking that shorted GPIO pins may have partially killed my Pi. But it was something else.



This is my Pi working normally.



This is what happens when you reduce its memory split to 8MB.

If your Pi is headless, put the memory split down to 1MB if you want for max CPU RAM, it won't care as long as there's no video output. Otherwise it'll artifact. If you're gonna have video out, give it at least 32MB I'd say, or leave it at the default 64MB etc if you've got the posh 512MB model, you late adopter smugsters.

Is it possible to boot into 80x25 character mode for simple console output with low video memory?

Just wondering what people are using to sample / log analogue signals? Just ordered the Arduino Uno R3 which seems cheaper and easier than putting together a gert board.

about to finish one of my projects on my first Rasp Pi (2nd one is just a HTPC running Raspbmc).

Basically, running MySQL and Apache/PHP. A PHP website updates values in the SQL database. A Bash script polling the database reads the values and acts accordingly.
At this stage, it plays different MP3s depending on the values entered.
working on a auto/random feature at the moment.

nothing too flash, but should be pretty cool when I sit it underneath my model train club's layout with some speakers and a wireless AP at the Model Train Expo next month

was also thinking, might be able to build my own retic system with a Pi and the GPIO pins...this would be basically the same.

Sounds cool. A headsup for anyone else that wants to do similar, I believe subsonic will run on raspberrypi. It's a remote music streaming server, but also has the functionality to 'play to host' so you can have multiple clients dictating what the pi plays out the speakers.

where's the fun in that?

Hence why I pointed out for anyone elses' benefit, not yours :P For those not interested in a challenge, but that just want a nice wireless audio box.
