A modder over at the Dell Mini 9 forums has created a cool dual touchscreen tablet mod using a Dell Mini 9 Netbook and a 9 inch USB DisplayLink monitor, and named it the Harlequin Project.
The Harlequin Project Dual Touchscreen Tablet Mod runs Windows 7 which detects both of the screens, and it works with the touchscreen overlay, although there are still a few minor issues for the modder to iron out which include calibration issues.
Technical Details and Challenges
The Harlequin Project is an innovative endeavor that showcases the potential of DIY tech modifications. The modder has successfully integrated two touchscreens into a single device, which is no small feat. Windows 7, known for its robust driver support, detects both screens seamlessly. However, the project is not without its challenges. One of the primary issues is the calibration of the second monitor’s touch functionality. The modder mentions that while Windows 7 detects all the drivers easily, the calibration for the second monitor’s touch input is slightly off. Additionally, the software CalTouch, which is used for touch screen calibration, does not recognize the second touch screen, adding another layer of complexity to the project.
Future Steps and Customization
The modder has outlined the next steps for the Harlequin Project, which include flattening all the components in the USB monitor and laser-cutting a custom case. This custom case is crucial for housing the dual screens in a functional and aesthetically pleasing manner. The modder plans to use two sets of monitor hinges to ensure that the screens can be unfolded at 180 degrees without touching each other. This is important because if the screens were to touch, it could inadvertently trigger the touch functionality, leading to unintended inputs.
I got the touch screens and monitors all working. Windows 7 detects all the drivers very easily, though calibration of monitor 2 touch is still a little bit off, and CalTouch doesn’t seem to find the other touch screen.
The next step is to flatten all the components in the USB monitor, and laser-cut a custom case for it. For the custom case, I will need two sets of monitor hinges, so that they can be unfolded at 180 degrees without touching each other (which would trigger the touch screen).
Implications and Potential Uses
The Harlequin Project is more than just a cool mod; it has significant implications for the future of portable computing. Dual touchscreen devices could revolutionize how we interact with technology, offering more screen real estate and multitasking capabilities. For instance, one screen could be used for primary tasks like browsing or document editing, while the second screen could serve as a virtual keyboard, secondary display for additional applications, or even a dedicated space for drawing and design work.
Moreover, this project highlights the growing trend of DIY tech modifications and the community of enthusiasts who push the boundaries of what is possible with existing hardware. It serves as an inspiration for others to experiment and innovate, potentially leading to new advancements in consumer technology.
Very cool, it will be great to see what it looks like when it is finished. Head on over to the Dell Mini 9 forums for more details on this cool Harlequin Project Dual Touchscreen Tablet Mod.
