Hi, I wonder if you can help. I'm just trying to replace the diverter valve on my 24dci, but have got stuck at the first hurdle. When I open the drain taps to empty the boiler nothing comes out! The system is still pressurised to 1 bar. I have even had the drain tap in my hand, but still no water. Any ideas on what I have missed

Hi

Great excellent device! a question though, what happens when the powers are out, in certain countries that happens very frequently.

Admin reply: Hi Nadia, if the power goes the feeder doesn't function. Here in the UK such events are fortunately very rare - indeed I've not had a power failure in 10 or so years. Of course, in areas where this might be an issue then a UPS would be required to continue operation - alternatively a battery backup which kicks in to complete empty the feeder could also be employed. All that said, I'd prefer to just call the neighbour for assistance - this feeder is purely for convenience and should not be placed in a life-or-death role! ..Mathew

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.

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.

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.

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 love your cat feeder! I'm giving a presentation for a public speaking class about home automation and will be referencing it!

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
