Cyberpunk themed macropad with 4 keys, one opens my own AI assistant, one enters my gmail anywhere i want instantly (log in or sign up) which is very useful. One opens Spotify, then my playlist, one opens focus mode on laptop, you set a timer and if you try to escape before that you get a tough math question and if you tell right answer you can escape. It will also have an rgb led and a display.
Before moving to the designing/3d printing, I wanted to make the Gmail macro key code. I spent around 30 minutes to write and debug the code (Might change after I get the parts. The Mission: Tap a single mechanical switch to automatically enter Gmail.
import usb_hid
from adafruit_hid.keyboard import Keyboard
from adafruit_hid.keyboard_layout_us import KeyboardLayoutUS
keyboard = Keyboard(usb_hid.devices)
layout = KeyboardLayoutUS(keyboard)
GMAIL = “prabhgunsinghsobti@gmail.com”
def type_gmail():
layout.write(GMAIL)
Phase 2: Design Inspiration & Cyberpunk Aesthetics (The Blueprint)
For the visual identity, I didn’t want a generic, boring plastic box. I spent some time studying past mechanical designs and custom cyberdecks. Color Psychology: Instead of standard monochrome, I locked in a high-contrast cyberpunk palette: A grey main enclosure to look like machined industrial metal. A matte black bottom floor plate to act as a grounded chassis. Vibrant purple keycaps to give it a sharp, neon color. The Centerpiece: A custom multi-layered knob in matching purple, with a neon yellow accent ring.
Once the vision was clear, the real battle began in Tinkercad. I spent 3 to 4 hours measuring real components and sizing them against physical hand.
Current Status: Design ready (Probably XD)! Every single part has been isolated, grounded flat at a height of 0, and separated with clear margins so the 3D printers can print them as individual components. Grey Enclosure -> Ready
Black Base Floor -> Ready
4x Purple Keycaps _> Ready
Custom Knob -> Ready
Next stop: Exporting the STL file and submitting it to the Hack Club #enclosure queue!
