Step 2Prep the 'touch light'
First, we need to make the cheap-o 'touch light' we got at home depot mood light-friendly.
First, flip the light over and remove the battery cover and screws. Inside the battery compartment, you'll see the lightbulb fixture. Take it out, and discard it and the lightbulb.
Next, open the casing. Now we need to deal with the power. Remove the piece of metal in the center of the battery compartment as well as the wire that connects it to one of the battery contacts. Solder wires onto the battery contacts as shown. You may also want to label them if you don't have differently colored wire.
We also are going to make this mood light operable via a wall outlet transformer. Drill a hole using a drill bit about the same size as the diameter of the DC power jack. Then screw it in until it is flush with the casing.
The last modification we need to make here is to add the piezo tap sensor. It is best to mount it on the plastic 'rim' for better sensitivity. I have it pictured later in this instructable mounted elsewhere, but that's only because I have had to open and close the casing during testing so much that the wires started to break. Simply hot glue it to the plastic, but make sure it does not hinder the mechanical movement on the movabke dome! (i.e. do not let it stick out too much).
