**Project:** DIY Motorized Monitor Lift for a Desk
**Goal:** Create a practical and "cool" mechanism to easily hide/show monitors on a work desk
**Summary:**
* Introduction to the project and its benefits (space-saving, practicality)
* Step-by-step DIY build process:
1. Building the base with a lift mechanism
2. Installing a motor, pulleys, and bearings
3. Creating a threaded bar system for support
4. Assembling the platform with captive nuts
5. Adding stability with aluminium angle guides
6. Incorporating limit switches for automatic stop
7. Wiring with a 3-position power switch
* Final result: A smooth, weight-supporting, and solid motorized monitor lift integrated into the desk, controlled by a simple switch.
Here are the key facts extracted from the text, each with a number and in short sentence form, excluding opinions:
**Project Overview**
1. The project involves building a mechanism to make a monitor platform disappear and reappear with a switch.
2. The build is designed to be budget-friendly using cheap, commonly available parts.
**Materials and Components**
3. The base of the mechanism is made from two long planks, end pieces, and top/bottom boards.
4. A high-torque, low-RPM motor is used to move the platform.
5. The project requires pulleys, wheels, 12mm diameter threaded bar, locking nuts, bearings, and a timing belt.
6. Right-angle aluminum bars are used for stability and as guides.
7. A three-position power switch is used to control the motor.
**Construction Steps**
8. The motor is mounted inside the base in the middle.
9. Pulleys and wheels are attached to the motor and the base using grub screws and thread lock.
10. A plank of wood (for the monitors) is clamped to the base and drilled for bearings.
11. Bearings are fitted into the plank with flange screws and self-tapping screws.
12. Threaded bars are trimmed and locking nuts are added to support the platform.
13. A timing belt is threaded over the pulleys and motor mechanism.
14. The platform is attached to blocks with captive tee nuts, which are then screwed to the threaded bars.
15. Aluminum bars are screwed to the base corners for stability.
**Electronics and Wiring**
16. Push switches (acting as limit switches) are mounted to wood pieces to automatically stop the lift.
17. The motor, switches, and a three-position power switch are wired together (schematic in video description).
**Final Assembly and Functionality**
18. The lift is placed behind a desk and secured with screws.
19. The switch controls the platform's movement, stopping automatically at the top and bottom.
20. The platform supports a surprising amount of weight and moves remarkably smoothly.
