The tap pad, built
The all-clear acrylic pad exactly as it's being cut: seven plates and two small risers, a little smaller than a phone and as thick as a stack of five coins. The reader sits under the tap ring. The ESP32-S3 sits up under the top at the back, so its OLED reads the right way up for the player holding the pad, and a cable plugs straight into its USB-C on the back edge. Drag to turn it, and switch to Exploded to see every layer.

On the tableA low, glass-clear slab with brass bolts at the corners. You can see every part inside; the ring tells players where to tap.
In the handAbout 125 g, roughly a bar of soap. Hold it by the front edge and the OLED faces you at the far side, the right way up. Corners are rounded to 12 mm so they don't dig into the palm.
From the sidesSeven clear layers with faint lines between them. One port: the S3's USB-C on the back edge, for power and flashing.
