Re: Detect GPIO states at program start

I believe the setup routines for the gpio pins will reset them no matter what you try, but just an odd suggestion, maybe try outputting the settings to a text file/configuration file, and have it save settings on exit, and load the settings on startup, then it'll tell what's what.

Re: Raspberry Pi and Xbee?

first of all, you need to make sure you disable console on the serial ports on the rpi, then you can just directly hook up the xbee to the rpi since both run at 3.3v, so no converter is needed. Here's a link of how to do that: http://cae2100.wordpress.com/2012/12/23/raspberry-pi-and-the-serial-port/...

try ebay, I know the one guy sells stuff like that, or varable buck/boost converters that handle up to 3A for decently cheap. like 3-5 USD for one with shipping added in.

Re: Bespoke .iso image

Re: Portable hard disk clone system

you can probably just take two external docks/enclosures and plug them in through a usb hub, then use dd command to clone the drive. The only thing I can think of that wouldnt work is if you only used one hdd and try to use the SD card to hold the image because of the size of the SD card being much ...

Re: Sending the PI to space (Pi Satellite)

your 3.5mm audo jack, Ive done that idea with an arduino board attached to the top of it, and had it set to a low baud rate, around 300 baud, and had the arduino convert it to pwm and used RC5 encoding to send data over radio for my one robot I rebuilt to give it a wireless remote control.

Re: Error: No module named GPIO

what python version are you using? python3 doesnt install it's gpio package through that, so it's only installed in python 2.x
you can try "sudo apt-get install python3-RPi.GPIO"
