Re: Jennet-IP Border Router

Hi
I have a working system now. Using a mysql database for authentication and scheduling of events to operate the wpan. Just need to working on some grouping functions but it's coming along nicely.

Re: Home Automation - Control via SSH

It depends on what you want to control and when. If you want devices to operate at specified intervals then the most obvious thing is to use cron. I want to control lots of devices with the pi so I use a mysql database to store the scheduled events and then I have a php script that is called from cr...

Re: 240v 500ma MOSFET questions.

Re: Raspberry Pi+Arduino+Xbee

You will not get an IP device to talk to a zigbee device without some form of gateway. 6LoWPAN is the way to go it allows IP based devices such as smartphone, PC or any other devices connected to the LAN/WAN to send packets to wireless devices. I am in the process of creating a gateway to do exactly...

looks to me like the ecobee is a zigbee based wireless control system. The thermostat contains a zigbee node which will relay the information via wireless 2.5Ghz to a remote web portal.

Re: Question about resistors

The resistor can be at any side of the LED. You can also sink the current so that current flows from the 5v supply into the GPIO of the PI simply setting the GPIO High will turn off the LED setting it Low will turn the LED on GPIO -------/\/\/\/\/\-------|<|---------------+5v 220ohm LED Sourcing the...

Re: Question about resistors

A current limiting resistor should be carefully selected to ensure that the current going through the resistor is limited to the current specified for the LED. Its basic ohms low to calculate what size resistor to use. Ohms law is V=IR where Voltage = Current(Amps) * Resistance(Ohms) We can transpos...

Re: Can't install software on the pi

You usually install using apt-get normally as the root user.

Search on google for installing packages on raspberry pi it will almost always use apt-get

for example to install a mysql database

sudo apt-get install mysql
