Run Your Favorite 8-Bit Games on an ESP32
NTSC color requires a precise frequency, but if you're fine with just black and white, you can generate NTSC B&W using an Arduino Nano (16 MHz 8-bit processor) and a couple resistors and crocodile clips and an RCA cable. (PAL B&W is similar and also possible.) There are even libraries that make it super easy; I have used this one: https://github.com/Avamander/arduino-tvout (IIRC I needed to fix a couple things to get it to compile).
With Raspberry Pi Picos and their 133 MHz clock rate it seems it's possible to even generate HDMI (and there are youtube videos demonstrating this).
I recently bought a couple crystals to generate the NTSC color subcarrier frequency. The Arduino Nano only has 2 KB of RAM so it's a very tight fit but I'm daydreaming about running a tiny BASIC interpreter on it like to build something similar to an old 80s computer that boots right into BASIC. (There's a small amount of free CPU time between frames and between scanlines, but my calculations indicated that you'd get a fraction of the performance of a C64, especially if you wanted to extend the RAM a bit (which wouldn't be directly addressable)).

Made an Arduino Space Invaders clone
The video output is generater through the TVout library (https://github.com/Avamander/arduino-tvout), which works on most Arduino boards (the Pro Minis with an Atmega168 seems to not generate a vide output). To hook it up, combine the SYNC pin (through a 1k resistor) with the VIDEO pin (through a 500 ohm resistor) to get the composite output. Only in black and white though.

Cannot believe it worked! Followed a sketchy guide for adding a Composite In line. I even managed to not electrocute myself
I’m assuming it’s the demo from the TVOut library https://github.com/Avamander/arduino-tvout

Ask HN: What have you built with ESPHome, ESP8266 or similar hardware
Not built, but designed a widget with a rest api on a wifi endpoint on one side and an IR led on the other to automate my dumb a/c unit. There was already a library to emulate the exact IR remote control,

I built an offline smart home, and why you should too
I am planning to do this soon(TM).
Probably starting with ESPHome to control my heat pumps over IR.
The remote works but I forget to turn it off when not in one of the rooms, and it can't do smarts like keeping temperatures in desired bounds.
An ESP32 running ESPHome with high power IR LED, a presence sensor, temperature sensor, and some pre-built library to control heat pumps[1]. it looks like it should be fairly simple to implement with Home assistant.
Now if I could only disable the beep from the heat pumps receiving commands.
I would like to do smarter lighting, but the lack of decent smart light switches that support local control and are also licenced for use in AU are a blocker there.

ThermTerm: an open source heat pump controller and home automation terminal, built on ESP32
ThermTerm solves all the problems I've had with these physical controls, while integrating the heat pumps into Home Assistant via MQTT. Additional sensors pipe temperature, humidity and light data, for statistics and automation. Out of the box, ThermTerm supports Mitsubishi's infrared protocol, since that's the system I have. Thanks to integration with IRRemoteESP8266, you can make ThermTerm work with your own heat pumps by writing a few lines of adaptor code.

Mitsubishi aircon control without HA/OH
This library has the IR codes defined for tons of heat pumps. The only thing about node red is that it uses Java to build the UI on the webserver. If your already familiar with Java then no big deal, but it's just one more syntax to learn lol.

ESP32 AC Remote
I used this library with a D1 mini. I then use this to put in my dashboard There are some examples one is a receiver code that you can get your codes, they also have a lot of ACs codes already. There is also an IRServer example that integrates with MQTT and has some stuff to put in your configuration.yaml so you can get it into HA easily I used this for 6 Samsung ACs, LG Dryer, some basic fans with IR. Samsung is the same each command is like all commands in one on, temp, etc. It has all this built in. I think if you have a IR receiver on your esp board and it will sometimes pick up the commands sent by the regular remote so if someone else uses the dumb remote it will update in HA. It's not perfect but it works pretty well. you can get all in one boards on ali express if you search iresp8255 they have transmitters and receivers.

MQTT & IR Receiver
I have tried https://github.com/Arduino-IRremote/Arduino-IRremote and https://github.com/crankyoldgit/IRremoteESP8266, both cause the same error.

Struggling to get IR transmitter working
First, try to remove the resistor(i was made an ir remote using the top circuit for ir sender). check the components, maybe one of them are dead. Second, check the gpio and config. Third, maybe the problem is the code. Maybe you should try the original IRRemoteESP8266 library first: You should checkout the original esp8266 ir remote library first: https://github.com/crankyoldgit/IRremoteESP8266 checkout my project: https://github.com/KD-MM2/MHI-AirCon-ESP8266/blob/main/Ver-1_Webserver_IRRemote/TurnOnMitsubishiHeavyAc.ino

Used the Flipper as a tool for this project - hacking a TV-B-Gone into a home automation IR device
I was able to finally read one of my remote codes that my other receiver couldn't with the flipper. I then used this library with a D1 mini.

My HomeKit AC controller..
My AC is fujitsu and I found library to control: https://github.com/crankyoldgit/IRremoteESP8266/blob/master/src/ir_Fujitsu.cpp

About to buy an air-codition - can someone recommend one which is not-so-closed-cloud and can be possibly integrated into HASS?
If it has a remote you can try to control it with an ESP32 with an extra infrared led. Check if it is supported by this library. Some coding would be needed.
What are some alternatives?
