This Off-Grid Raspberry Pi Entertainment Rig Packs 5TB of Storage, HDTV Reception, and LTE
Pseudonymous maker "treasurehunter613" is perfectly prepared to stay entertained whatever the weather — thanks to a low-power off-grid TV and media playback system driven by a Raspberry Pi.
"My amazing off-grid LTE internet/OTA HDTV/Raspberry Pi 5TB NAS over Wi-Fi system [is] powered by three USB ports and a 12-volt socket outlet for the HDHomeRun HDTV tuner), and consumes only 5 to 10 watts of power," treasurehunter613 explains of the project. "This system was designed with power efficiency in mind. Everything is accessed with a smartphone/tablet using VLC over Wi-Fi! No TV required!"
The core of the modular system is a Raspberry Pi 3 Model B+, which connects to a 5TB USB hard drive and acts as a media server for video and audio files. For live TV, there's a SiliconDust HDHomeRun Extend HDTV tuner, while a D-Link DIR-605L Wireless N Wi-Fi router provide a local Wi-Fi network for smartphones, tablets, and other client devices.
There's one more string to the project's bow, though: A Netgear LM1200 4G LTE modem, providing cellular connectivity when the rig is taken on-the-road in its creators' RV. "I have a Rogers Infinite plan here in Canada that allows you to pay an extra $10 a month to share your smartphone data with a hotspot device," treasurehunter613 explains. "You get two SIM cards, one for your smartphone and one for your hotspot."
Everything is powered, meanwhile, by a Bluetti EB240 2400WH Power Station. "The system as it is runs for 7.5 days before needing to be recharged," its creator explains. "That will change once I start using it to also charge my smartphone/tablet, etc, however I will have 360 watts of solar panels connected so in theory it shouldn't really have time to discharge much at all."
