Tom! I will print these instructions out and carry them with me so I can show them to someone who has the requisite skills to put the gizmo together. ----- Original Message ----- From: "Tom Fowle" <fo...@ski.org> To: <blindhandyman@yahoogroups.com> Sent: Thursday, December 03, 2009 1:46 PM Subject: Re: [BlindHandyMan] Inventors ahoy!
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!
