The first Tardis is 3D printed, with arduino and SD card to generate sound effects from the speaker, and to create the LED lighting effect.
Second Tardis is laser cut plywood with ESP8266 (Adafruit Huzzah), 2 line LCD (for debug, date and time display) and 7 Segment LED to go in a window to show the current time. Gets the current timezone and daylight adjusted time from an internet web service so the clock is almost always correct, and of course the LED lamp lighting effect.
The laser cut plywood Tardis looks close to my Tardis.
