Want to build a portable "TV" video display unit? An old laptop screen serves as a great starting point for building a display panel, and an HDMI driver board makes it easy to connect the display to a computer. The next step is adding a battery pack, making it portable, using a pair of voltage regulators to set up the 12 volts and 5 volts required to power the components, and an external charger to recharge the batteries. A sound bar is easily buildable using a set of small speaker drivers and audio amplifiers. The "television" portion is a question mark, however since it's nearly 2020 we can easily connect this to the Internet for video streaming using a Chromecast or other HDMI gizmo. The parts can be easily enclosed in a case, and voila you have a complete and portable video display system.
