I have three possibilities. 1. If you have a 9 volt water level indicator, use it. Use your plate of food to hold down a sheet of aluminum foil folded so that one side sticks up. Place the water indicator so that the two leads are very close to the foil, but not touching. You will have to try it to see if the buzzing sound is enough to effedt the dog.
2. Using a coil of fine wire, such as a solenoid coil, connected to a 9 volt battery, you can give a dog a very nice shock when he touches something you do not want him to touch. This setup makes a shock only when connection is made and when the connection is broken. It is not dangerious. With the battery clip connected to one lead of the coild, use the other coil lead and the unused battery clip lead to be close to each other but not touching. When the dog makes contact of both leads, he get a shock, but it is only one quick shock with no current. 3. Many years ago, we had a dog that liked to steal from the table. We took a throw away tray that some meat came on from the store. We piled up every pot and pan in the house on it. In the middle of the night we heard a crash. That dog never stole again.

Hi Jewel, I've noticed recently trained guide dogs I've seen are much more prone to such inappropriate behavior than they used to be. I'll not subject you and the list to my somewhat prejudiced opinions about why <GRIN> The device is electrically simple, and I bet you can find the parts at a radio shack if you have those available. All you need is a battery, probably 9 volt with connector, a 'normally closed switch of the push button type, and the noise maker. I bet shlock sells a lout alarm type noise maker all in one just what you need, I'll get my wife to look some time in a couple days and see if we can give you a number. Most push button switches have 3 terminals, the "swinger" and normally closed and normally open contacts. You just wire a loop with the battery, it's negative terminal going to the negative terminal of the alarm, the positive battery terminal goes to the "swinger" of the switch, and the "normally closed " contact of the switch goes to the positive terminal of the alarm. that means the thing is not screaming till you release the button. The trick is packaging it the way you like. You could even make a box with a hinged top arranges so that when the top has no weight on it, the switch is not pressed, but when the top is pressed down by more weight it presses the switch nd opens the contact the contact to the alarm. If you can build it your self, you're more likely to get what you want physically than if I for example built you one, but I could do so if nobody closer offers. You don't have to solder wires, small "wire nuts' should do the job, just strip wires, twist together and maybe add a bit of tape. Rest is obtaining the box, parts and deciding how to mount stuff. does this help any? tom Fowle ------------------------------------ Send any questions regarding list management to: blindhandyman-ow...@yahoogroups.com To listen to the show archives go to link http://www.acbradio.org/pweb/index.php?module=pagemaster&PAGE_user_op=view_page&PAGE_id=33&MMN_position=47:29 Or ftp://ftp.acbradio.org/acbradio-archives/handyman/ The Pod Cast address for the Blind Handy Man Show is. http://www.acbradio.org/news/xml/podcast.php?pgm=saturday Visit The Blind Handy Man Files Page To Review Contributions From Various List Members At The Following address: http://www.jaws-users.com/JAWS/handyman/ Visit the archives page at the following address http://www.mail-archive.com/blindhandyman@yahoogroups.com/ If you would like to join the JAWS Users List, then visit the following address for more information: http://www.jaws-users.com/ For a complete list of email commands pertaining to the Blind Handy Man list just send a blank message to: blindhandyman-h...@yahoogroups.comyahoo!
