Cyber Clock 2.0 (Stainless Steel Exoskeleton)

Forget mass-produced toys! This hands-on guide will walk you through building a miniature Cybertruck packed with real tech – from 3D printed parts to a powerful microcontroller brain. We'll tap into the DIY revolution, where open-source designs and accessible tools empower anyone to create amazing things.

Even if you've never soldered a wire or seen a circuit board, you CAN do this. Follow along as we demystify electronics, conquer 3D printing hurdles, and write code like a pro (with a little help from AI).

This isn't just about a cool project – it's about unlocking a world of possibilities. Embrace the maker spirit, challenge your limits, and witness the magic of bringing your ideas to life! Are you in?

This is a replica of the original Cyber Clock Project by Gokux.

Supplies

3D Printed Parts

You can order these from commercial grade PCB manufacturers or you can print them yourself.

Assembly

Diagram

3.1 - Kapton Tape

Apply a piece of Kapton tape under the plus and minus battery terminal pads.

3.1 - D1 Battery Data

Solder a wire connecting D1 to both the battery terminal pads separated by 10kohm SM resistors. Also connect the 3.7V battery and power switch.

3.2 - DHT Module

Trim the DHT11's pins to the needed length. Connect a 10k resistor between its VCC and DATA pins (I'm using a through-hole type). Then, solder three wires to VCC, GND, and DATA, making them long enough to reach the Xiao's corresponding pins.
