Turning the Raspberry Pi into a Wireless Access Point

Hi! Following my latest posts on how to get started with the Raspberry Pi "headless mode" and Using Bluetooth with the Raspberry Pi now I'll show how to turn the Raspberry Pi into a Wireless Access Point.

After some reading I verified that the USB ports of the Raspberry Pi can only source 100mA to a device and maybe the cameras are consuming more than that. To bypass that problem I went out to buy a USB hub with external power supply.
