Jan: It will be a box, to put some photos or cards in it. The box could play some music or sound.
Feb: To compare with laser cutting and 3D printing, mostly 3D printing seems better. I haven't made the decision yet, but I will not use plywood, if cut it with laser cutter, the smell and the surface will be not good.
Mar: I will use XIAO ESP32-C3 to control the box, RFID will be the module to trigger the music or sound.
