The latest Issue (82) of the MagPi magazine features an article, starting on Page 38 with details about how to build a Pi Keyring.
On Page 41 of the same article, there is mention of using the Pi to create a Hotspot.
I am a regular and very satisfied user of VNC at home (both from a Windows PC and an Android phone) but someone please confirm that the article does mean that (In my words) a Pi can be used where there is no internet and can be used to create a WiFi Hot Spot that I could log into from an Android Phone and therefore access and Program the Pi.
The application I have in mind for this is to be able to use the Pi in a Caravan where it will, for example, be used to monitor the water level in our Fresh Water tank and provide warnings of a low water level. I am able to construct the necessary electronics for the sensing and indication but I am not sure I have understood the article correctly regarding the WiFi Hotspot.
