-N/A
+The bus is a standard CAN-bus with an additional 12V supply powering all nodes.
+Almost all nodes are using a base node with an additonal application specific expansion card.
+All nodes has a bootloader so the software can be updated over the CAN-bus. See [[hardsoftware:canBootloader]] for more info.
+{{:hardware:cannode.jpg?320|CanNode - base node}} canNode. This is the base node. It is build up around a Microchip 18F2685 CAN microcontroller, has a 2551 CAN transceiver, a 5V regulator, two micromatch CAN-bus connectors and a ICSP-contact.
+The following nodes are or are going to be on the bus:
+{{:hardware:cantemp.jpg?320|CanTemp}} canTemp. Uses canNode. Messaures temperature outside and inside the apartment. Can also turn the blind of my top right window.
+{{:hardware:servo.jpg?320|CanTemp - close up}} Another view of the servo/blind connection.
+__canFreezer:__ Uses canBase. Messaures temperature in the freezer and refrigerator and monitors if the freezer and refrigerator doors are open or closed.
+Status: Software done. Schematic done.
+Todo: Expansion card.
+__canLCD:__ Uses canNode. Control panel next to the outer door. Messaures temperature outside and if the outer door is open or closed. Also has a 128x64 graphical LCD which displays different sensor values and where things like light and blind can be controlled (all acuators on the bus).
+Status: Software done. Schematic done.
+Todo: Expansion card.
+__canIR:__ Uses canNode. Receives command from a remote control using the RC5, RC5-E or RC6 protocol. Can control all acutators on the bus.
+Status: Software done. Schematic done (connect a IR-receiver to a canNode basicly). Has a working prototype on breadboard.
+Todo: Expansion card.
+__canIRtrans:__ Uses canNode. Send IR-commands to systems like TV, surround receiver, etc.
+Todo: Software, schematic and Expansion card.
+__canDimmer:__ Uses canNode or application specific node. Can dim 230V lights like regular light bulbs, halogen, etc.
+Todo: Schematic, software (has an old from lightDimmer that can be used), and maybe expension card.
+__canToSerial:__ Uses canNode. Works like a wrapper between the bus and RS232 for montioring and controlling the nodes from a computer.
+Status: Software done. Schematic done. Has a working prototype on breadboard.
+Todo: Expansion card.
+{{:hardware:home_exp_ethernet.jpg?320|CanEthernet}} __canEthernet:__ Uses canNode. Works like a wrapper between the bus and internet (TCP/UDP) for controlling the nodes from internet and mobile phone.
+Future nodes, only abstract ideas so far.
+__canBed:__ Node that messaures the weight of the bed. By analyzing the weight changes in the bed it's possible to see eg. how much a person turns during the night.
+__canVoice:__ Voice recognition node. Makes it possible to control all actuators using voice commands.
 ===== Software =====
-N/A
+There is no PC control software yet, but there is a couple of monitoring/debug applications. All written in C#.
+{{:hardware:canwatcher.jpg?320|canWatcher}} canWatcher. Can send and receive CAN-packets.
+{{:hardware:canwatcherlight.jpg?320|canWatcherLight}} canWatcherLight. Same as canWatcher, but a light version.
+{{:hardware:canbootloader.jpg?320|canBootloader}} canBootloader. See [[hardsoftware:canBootloader]] for more info.
