Beset by handheld games consoles, being used by various offspring post-Xmas, I’ve become aware of how important it is to limit the obsessive usage of these.
Today’s invention is an additional, password-protected interface on all such devices which allows a responsible adult (or even a meanie parent) to specify in advance times when they may be used.
This might have a small alarm to alert the user when access is allowed and also when it’s about to end.
