If you have always fancied getting your hands on one of Microsoft’s Surface computers but didn’t want to cough up the $20,000 and were looking for a cheaper version, the guys over at Instructables have put together a handy guide on how to build your own Multi-Touch Surface.
This one is still quite expensive to build, coming in at around $2,500, but it is considerably cheaper than buying a Microsoft Surface.
If you want to build your own Multi-Touch Surface, you will need quite a few components which include a projector, a PS3 Eye camera, and some custom software.
Components and Tools Needed
To get started, you will need to gather all the necessary components. Here is a detailed list of what you will need:
- A projector: This will be used to project the image onto the surface.
- PS3 Eye camera: This camera is essential for capturing the touch inputs.
- Custom software: Software is required to interpret the touch inputs and translate them into actions on the screen.
- Infrared LEDs: These are used to create the touch-sensitive surface.
- Acrylic sheet: This will serve as the touch surface.
- Wood or metal frame: To hold everything together.
- Various cables and connectors: To connect all the components.
Building the Multi-Touch Surface
The process of building your own Multi-Touch Surface involves several steps. Here is a brief overview of what you need to do:
- Construct the Frame: Start by building a sturdy frame to hold the acrylic sheet and the projector. The frame can be made from wood or metal, depending on your preference and available materials.
- Install the Projector: Mount the projector in such a way that it projects the image onto the acrylic sheet. Ensure that the projection is clear and covers the entire surface.
- Set Up the PS3 Eye Camera: Position the PS3 Eye camera so that it can capture the touch inputs on the acrylic sheet. You may need to experiment with different angles to get the best results.
- Install the Infrared LEDs: Place the infrared LEDs around the edges of the acrylic sheet. These LEDs will create an infrared light field that will be disrupted when you touch the surface, allowing the camera to detect the touch points.
- Connect Everything: Use the necessary cables and connectors to connect the projector, camera, and LEDs to your computer. Ensure that all connections are secure and functioning properly.
- Install the Custom Software: Download and install the custom software from Instructables. This software will interpret the touch inputs and translate them into actions on the screen.
- Calibrate the System: Once everything is set up, you will need to calibrate the system to ensure that the touch inputs are accurately detected and translated into actions on the screen.
