Comments: Just a quick message to thank you for the article regarding a diverter valve replacement on a Worcester 24CDi Boiler. Very helpful indeed, especially when I forgotten where to put the fibre washers ! Thanks again, Tony.

Comments: RE: the Cat Feeder... WOW! I too have looked for a reasonably priced feeder that would work. The best feeder I found was in the $500.00 US range. Crazy price, but probably worth it if you could afford it. Your use of a cereal feeder was a good idea, I've been playing with an old 'Beaver' Gum dispenser, but it's big, noisy, and needs a LOT of torque. You didn't mention what the smallest serving would be with your system? I'd be feeding 1 cat maybe 4 to 6 times a day. That would be 1/2 a cup of feed divided by 4 or 6, a pretty small serving. Perhaps gluing a block onto the rotating device would limit how much feed comes out. Thank you for the links to your sources of materials and some of the scripts. While I wouldn't need the split system for the feeder I'd love to see that one piece of aluminum opened up & how you folded it to create the chutes. How do you design something like that? Beyond me... An amazing product! I'll be tinkering using some of your ideas, but I'm afraid I'm not as computer literate as you so I'll be looking to simplify the system.. Congrats on your hard work.
Comments: Just spent an hour stripping down my WB28cdi to replace the diaphragm. Wouldn't have dared to tackle it without your excellent guide, so many thanks. Off to bed and then rebuilding in the morning. I may leave a different comment tomorrow if it doesn't go back together again Excellent stuff, thanks.
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
Comments: 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
Comments: 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
Excellent stuff, thanks.
