Amazing concept, thanks for sharing it

However I didn't get how you deal with unexpected broadcast ethernet packets, they would normally be repeated on all ports of the switch, wouldn't they ?

Unless the use of VLANs prevents broadcast packets to be repeated on all existing VLANs. Is that so ?

Admin reply: Got it in one! That's one of the benefits of VLANs - they limit the size of broadcast domains. In this case, my control ports are in their own respective VLANs hence are completely untroubled by anything else that happens on the network. ...Mathew

I would probably do it with one of those cheap Wal*Mart Linux warts and USB, but I love the idea. I was most interested in the cat door, allowing "authorized purr-sonel only" access.

Admin reply: Heh, nice one Don't give up the day job though Bill! ...Mathew

Excellent idea, the layout slightly resembles my old XJ6 both in wiring and detail solutions.

Keep the good work up!

Admin reply: Thanks! XJ6 you say? I'll take that as a compliment, I think! ...Mathew

I would like to expand this idea, and build a USB version of this. I will keep you posted if I decide to make this happen, possibly there could be a market for something like this.

Admin reply: Yeah, there are many ways to skin this... err.. cat. Do post back if you get anywhere! ...Mathew

Admin reply: That's excellent news, on all accounts! Well done for doing it as it's not the easiest of jobs, as you now know! Excellent timing too, what with the freezing temperatures at the moment and Christmas only just round the corner. Hope you have a good one, and all the best for the New Year! ...Mathew.

If you were to find the most inexpensive, simplest solution, what would it be? A USB wireless device? Wires attached parallel/serial port? While your solution is entertaining, it may not be practical for many users. So if you had to do the project over again using the most inexpensive approach, how would you do it?

Admin reply: Good question Mike! To be honest if I were to do it again, for myself, I would probably do it exactly the same way. Cisco switches are extremely cheap - they're almost given away on eBay, literally. However, for others wishing to do likewise who might not like the idea of hacking an existing piece of equipment I suppose I would instead suggest seeking out a cheap network-enabled relay. Whilst I didn't find anything I probably didn't look hard enough, not least because I already had a good way forward in mind. Of course, if you can have the feeder near your PC then just use the serial/parallel ports as you suggest. Otherwise, I think a co-located dedicated PC just for the feeder is overkill... (that said, some would say the whole project is anyway!) ...Mathew.
