Build your own portable SMART TV (100% wireless!)



Want a better experience watching media on your smartphone? This DIY build should be right up your street! In this one we’ll be building on the previous portable monitor project and designing a battery system and speakers for it to transform it into a high quality wifi TV!

Previous video that this one is based off:

Purchasing links below.

Third Hand:

Chromecast (official):

Speakers:

Amplifiers:

Voltage meter:

Voltage regulators:

Battery box:

Charger:

BATTERY METER CALIBRATION:

The bottom variable resistor sets the high voltage point (or ‘full charge’ voltage), so set this first when batteries fully charged; clockwise lower voltage, anticlockwise higher voltage.

The top variable resistor (near the button) sets how broad the range is, so set this afterwards to get the low voltage point at low low battery power, anticlockwise lower, clockwise higher. Low voltage should be about 10v when the batteries have no load connected.

The clips playing on the screen were from the trailers for Planet Earth 2 and Assassin’s Creed.

    Could you create a 144hz gaming monitor using this system?

    a few things I did different was I quadrupled the amount battery's and got a brand that lasts longer in total I can stream for 8 hours before needing to recharge even then i added a option to where i can plug it in so it doesn't need to use the battery's, in fact I made it so I could switch to a mode where it wouldn't charge the battery's past 99% (to prevent battery strain) and would still power the TV but not the battery's so i made it have a ton more functionality

    even in 2016 I would have used a rechargable powerbank instead of batteries

    Looks great, but is it really worth it, basically if you don't have anything mentioned, it might just cost me close to $80usd for lcd,boards, adapters and so on.
    AliExpress has 2k screens for around $100usd.
    I enjoyed your video and got me searching but for regular guys without spares it's not feasible.

    But what about the fact that chromecast is really inconvenient to set up on a new wifi? Makes the battery powered aspect kinda low utility. Plus it doesn't work at all without a WiFi to connect to.

    Instead of a chromecast use something like an amazon fire tv stick that comes with a remote and full android so you can easily stream anything to it and even game on it

    Using three 18650 li-on batteries in series with a BMS board would have been better _ in my opinion.

    To make any of those projects you need a full equipped workshop, you need to buy a lot of 'cheap' stuff online and skills .. Not worth it.. With 130 euro i can buy a very good 32 ' smart tv so..

    Any chance for an updated guide for this? I know not much has changed but I thought there might be a better components that are more easily sourced to build it. I suddenly have some extra time on my hands and thought this might be a cool project.

    Since I will be taking my screen out of a laptop what steps would I need to use the battery from said laptop instead of the AA rechargeables in this project?
