"I am currently a resident in a  nursing home and have difficulty with what they have as a call light. When you press the button by your bed a small LED light comes on above the bed. The problem is I am visually impaired and cannot see if the small led Is on. After waiting a while  I'm always having to press the button not knowing whether the light is on or not.

 

I would like  to find some kind of light sensor that I could place over the small  LED and have it BUZZ or give  some kind of  audible sound  so I know  the button has been pressed, I do have  my desktop computer a few feet away and thought about  having some kind of  USB device that could have my computer produces sound, I am enclosing  a picture of the wall plate where the LED is located.

 

I have had dreams of since it was hooked to my computer I would be able to keep a log of how long the light was on each time it's on. Thank you  in advance  for any help"

"+Fr. Robert Ballecer, SJ I know on your recent travels you had mentioned a new Mobil Hotspot you were trying. I have an upcoming trip and want to look into one you used. Looked through recent KH show notes and did not see mentioned. "

"To all the users of Synology's Surveillance statioStation wondering if any of you guys bought additional device licenses.  I have the DS216 Play and already am using 2 cameras, but tempted to add maybe 1 or 2 more.  Curious if I'm the  othe onlythat considered it. LOL"
