> It does have a problem however, the TV tends to hit resonance frequency very often with its built-in speakers, causing the body of the unit to vibrate something awful and produce some ear wrenching sounds as a result.

"Gosh that sounds like our LG"

"Of course it's a fucking LG."

There are many bars available which have remote control learning.... e.g Yamaha YAS-306. Its just 2-3 mins job and you dont have to do these hacks. I have one from early 2000s which works perfect.y

This article is about replacing the IR remote control with an HTTP interface. Are there any bars available on the market that can learn how to pick up such wireless transmissions and respond to their requests?

Not crapping on this project because it's hella awesome, but a more scalable solution (which might not be worth it at all) would be to make a HTTP interface to a remote control, then have the remote control beam IR signals at whatever. This would mean that for any new device you add, you just have to pair the remote instead of wiring up another Pi to it.

Good post. Honestly though, I’m more interested in making smart devices dumb. Rip out their Wi-Fi hardware etc.

I find it easier to start with a dumb device. However as that increasingly looks not so possible for TVs, I'd love to see somebody document the process for what you propose.

Wal-Mart's Sceptre brand still sells a wide range of dumb TVs. Not super great performers, but also not expensive by any means.

I've had thoughts of a project for making my TV smart but never got started on it. I think developing a ML vision model for detecting commercials during sporting events or detecting YouTube ads and when the skip ads button appears would be a fun and not too complicated project. But connecting it to hardware with an infrared remote seemed significantly harder and this project confirms my worry. It might still be possi…

There's already tooling to do this, back when MythTV in 2005ish (iirc). Also, this for Youtube. It's enabled on StreamNextTube and works a charm https://sponsor.ajay.app/

MythTV commercial skipping was absolutely magical. I understand at a high level how they did it; there are lots of obvious heuristics you can use for this (black detection, silence detection, observing the CBS logo/bug going away, etc.) I also find it fascinating that this was never described as "AI" back in the day; today it would 100% be.

Neat project! I used Python Dejavu to recognize audio from a library of known commercials. A more general commercial detector via a ML model would be great!

When a commercial is detected, the program sends a http request to a local server running on a Raspberry Pi. The Pi has an infrared remote control transmitter, and uses LIRC to send commands to a Polk sound bar.

That's actually really cool. I have a polk soundbar, which already does have a IR remote, but it doesn't actually do anything...

For the most part, don’t connect to Wi-Fi and use hdmi in. If you’re one of the lucky few with a tv that will wardrive your neighborhood looking for open networks, find the Wi-Fi chip and pull it off.

I did something similar. It seems a bit easier to set up honestly.
