Creating a DIY photo booth can be a fun and affordable project. This guide focuses on a simple method for creating a button trigger using a repurposed USB keyboard. This allows for easy photo capture without relying on complex software or timers.
This project hinges on understanding the internal wiring of a standard USB keyboard. A basic, inexpensive keyboard is ideal for this project. Disassemble the keyboard carefully, exposing the circuit board. The goal is to identify the two connection points corresponding to the desired key, in this example, the “C” key.
Tracing the circuit paths from the key itself back to the main board is crucial. A visual inspection of the traces on the circuit board is usually sufficient. Once the correct connections are identified, carefully solder two wires to these points. Precision is key here to avoid bridging connections and causing unintended keystrokes. Ensure the soldering is clean and secure for reliable operation.
To integrate the button into the photo booth structure, a simple housing can be crafted. A metal disc with a center hole allows for wiring to pass through while providing a mounting surface for the button. A standard momentary push button switch with threaded housing is recommended. This allows for secure mounting using a nut on the backside of the housing.
The metal disc can be sandwiched between the photo booth wall and a decorative wooden cover plate. A hole drilled through both the wood and metal allows the button to protrude. Screws securing the metal disc in place also hold the wooden cover. The switch should be inserted through the wall first, followed by the metal disc and then secured with the wooden cover plate and screws. This creates a clean and finished look for your DIY photo booth button.
This simple setup provides a reliable and user-friendly way to trigger photos in your DIY photo booth. The “C” key, when pressed, can be configured in your photo booth software to activate the camera shutter. This method avoids complex circuitry and provides a satisfying tactile experience for users.
