I think I will design that gadget which can warn me if someone has left that door half-open again. Why do they leave doors half open, closed or open? Why do the cleaners always leave their trolleys exactly where the door entrance is supposed to be? OK, I understand; whenever I hit a trolley, it tells me where the door opening is, so now I have found it at last... And, as for your mechanical liquid indicator; look inside the tank of any toilet; you'll see a big ball, floating in the water; is that the kind of thing you're thinking of?LOL! I don't think I'll be interested in having coffee with you if you used that kind of indicator? I think I'll rather have a beer, thank you!??? Deon [G.

This is because, I suppose, especially in weather like we're currently having up here in gauteng, the steam from something like coffee/tea can really cause hassles if you try use an electronic pouring sensor at all...<smile> Secondly, wondering about some or other form of keyring type tag you would maybe attach to other things like rucksacks etc., and where you could do something like turn on/off a motion sensor on it with something like a slider switch, just so that you could, for example, put something in one place, and be sort of notified if it was then moved as such, and, I suppose something like that might be useful to both blindie parents for attaching to their children's clothes, or for use by dog owners, as well as generally using it for maybe making sure you knew where a handbag, rucksack, etc. were..? You do already get sort of key rings with little audio beeps they can emit when you then activate them using a separate form of remote control, but, just thinking about something with it's own form of motion sensor in it so it would notify you itself if it was moved, sort of automatically..? Suppose something like that might also be of interest as a form of notifier if something like a door was opened, etc., as well? That one also brings up something that have thought for a while might be interesting/useful for finding things like keys, coins, jewellery, etc., and for this (really) last one, suppose some types of toy shops might actually be the best place to look for something like a cheap/simple, relatively ruggedly manufactured metal detector gadget? Only issue there might also be that it would have a limited range/focus area as well, but anyway..?
