OK, so I don’t have the fancy, dance to the music, lights, but I did a little something different this year. I decorated my mailbox with numerous multi-color LEDs that I soldered to strips and screwed them to the mailbox. They run off 3 volts so I had to make up a little regulator circuit for them. Then I found out I was exceeding the current for the circuit so I had to make up another. I solved the heat problem with the regulators by attaching them to little copper plates to be cooled by the cooler weather outside.
