So if we are all learning something new everyday, tips, tricks facts, whatever why not share!
So to start it off, something i learnt today!
If you want to see if a remote control is working, turn on your digital camera (any camera that doesn't use film), point the remote at it, and press a button. You should see a flashing purple light in the display of the camera if the remote is working!

Great way to see if its the batteries or not!
So what is something you learnt today??
