# Ploopy ![A photograph of 3 trackballs. The left two are small: barely larger than their mini snooker ball. The one on the right is larger, both because it has a larger 45mm-diameter ball and because it has buttons surrounding the ball](20240827_ploopy.jpeg) From left to right: Ploopy Nano as shipped, home-printed Ploopy Nano with Ball Transfer Units and a steel ball, Ploopy Adept kit in "translucent" PETG. ## Nano Excellent size! I wish it had some buttons on it. ## Adept Has buttons on it! By default: 1. Top left: `KC_BTN4` ("back") 2. Top middle-left: `KC_BTN5` ("forward") 3. Top middle-right: `DRAG_SCROLL` (custom keycode. hold the button and move the ball!) 4. Top right: `KC_BTN2` (right click) 5. Bottom left: `KC_BTN1` (left click) 6. Bottom right: `KC_BTN3` (wheel click) ### TODO 1. The wheel click doesn't seem to do anything. 2. `DRAG_SCROLL` seems backwards. 3. It'd be convenient if there were a proper reset button. 4. I want a cooler ball. Current one is 45mm. Is that a standard billiard size? Can I get brass? 5. BTU mod, obvs.
