Re: New to Raspbian and Linux? Start here...

Does raspi have a irc channel? New users can get faster one on one help better via irc then on a forum; at least for simple things that don't need a new thread.

maybe?

phpBB to SMF

I'd like to request the admins consider switching the forum software from phpBB to SMF. SMF ( http://www.simplemachines.org/ ) has a few features that I believe make it a better choice for more active/divided communities (better thread tracking for users comes to mind). I know you don't yet have any...

Re: new to python

The best way to learn from my experience is start with something easy, and program for it. Books are nice, if you have the time for it. For instance, first program a number guessing game. The user has 10 tries to guess a number between 1 and 100, and the program tells them if they are high or low. ...

Re: What is the LOWEST level language??

Early devices used the first typewriter technology of flying typebars, which were prone to jamming. (Did you know that the QWERTY keyboard that we all have even now was designed to be inefficient, to prevent fast typists jamming the machine?) At least, we now had lower-case letters!

Re: Automotive Entertainment System

Use a small capacitor and a GPIO pin car power ---> capacitor ----> raspi |--------> GPIO ------> program 'shutdown -h now' when power off if you get the right capacitor you wont have to worry about heat damaging the thing and you'll get a good 20-30 seconds of extra power to halt the pi.

Re: Rasberry Pi Controlled Quadrotor

The problem is not that the Raspi can't do it all but that it also has to do other things too. i.e. reorganizing memory, deleting tmp files, calculating uptime, running cron jobs, moving log files. Because of that if you want to bank left but the Raspi wants to log 'x' then your command will have to...

Re: Rasberry Pi Controlled Quadrotor

My friend and I are working on a similar project. We've decided that for what we want to do we need realtime support and don't want to build it into a Raspi yet, so we're pairing it with an Arduino board for flight control.
