    Text delay when typing is now fixed.

    There was a slight delay when you were typing and it was down to the smilies bar I had installed. So I've removed it. But not the smilies. Those are added to a post by clicking the happy face in the text options area now.

    I'm trying to find a way to delay the lights coming on after the switch is turned on - this is so I don't disturb my wife when I go to our ensuite bathroom which has the light outside the room. I've thought of 4 ways: 1) Put a pull switch inside the bathroom - it's not our flat, so that would...

    I recently purchased an old 2003 Smart Car as a 2nd run around car. I've noticed recently that some times when I turn the head lights to dipped or main beam there might be a long delay before they actually switch on. Some days it is instant and others I have this problem. Also the dash back...

    Rcbo

    I should know the answer but I don't and have tried google etc so that's out of the way for starters. Reading a post about sockets used for IT equipment and the possible problems caused by RCD tripping due to start up earth leakage, led to think about protecting the circuit with RCBOs with a...

    I've been asked to install 2 electric showers. That's the easy bit. The client has asked me if I can install a timer so they will only run for a maximum 10 minutes. Is this possible? The reason is to stop the kids spending hours in the shower and save on energy.
