[Trainer-Talk] screen monitor

[Raul Gallegos]

One of my favorite tricks to tell whether a monitor is on or not is using 
the light probe for $20 that can be purchased from the nfb independence 
market. This is an ugly little contraption that makes a sound when it 
detects light. The nice thing about this probe is that it is sensitive 
enough that you could even use it for the small LEDs of appliances. We have 
used it before to detect which light is on with the dishwasher for example. 
In the case of a monitor, if the monitor is power light is on, this probe 
will be able to tell you. Additionally, you could put the probe up to the 
monitor screen and many times it will also indicate if light is on.
