Hi Dave
those 20,000MCD Leds not badly priced.......approx $4.50 each....Are these
the ones your going to use???

Well if you are going to use Canbus then my hv interface could be rs232 or
rs485 . I would then need to connect any further devices on the can
network......A rs232 interface would probably suit those that are using
pc,s for control....Also maybe keep in mind ...using this for garden
lighting as well..........

Maybe  a bulk buy on leds might be the go.........

Hi Frank,

http://www.ervan-int.com/cgi-bin/products.pl?category=ledlamps_lamps
 The
prices there knock spots of the Farnell ones.

CAN bus would be the primary interface and the link between the modules,
but
to allow others to control the lights, I would add an RS485 slave interface
that you could send and receive commands via this to the CAN bus modules. I
won't be going the whole xap, xpl route as it will be a simple telemetry
interface only.

I am open to any and all ideas for the final design as I have only just
started to put it together. Currently working on the PWM to see if this is
the best way to go for lamp control.

Regards
Dave...

Hi Dave
Any chance of the link to have a look..........

On the Can_bus side would it be possibe to control it via Homevision /
rs485 network..??? Would i assume require a rs485 / canbus interface.......
