Weather Prediction Electric Cushion

My butt was always cold.What if AI always sets my butt to the right temperature.I'll be able to concentrate on my work without having to wear it on my butt.

Hardware

The main board is the Raspberry Pi Pico. I used the W5100S PoE board that we worked on for Ethernet communication. The PoE board can receive up to 10 W of power.

I used FET to send 10W of output to resistance. It's not a big power, so I brought a nearby FET and used it. As you can see, we also have damping resistance.

First of all, we tested by connecting 4 20 ohm resistors in parallel.When I printed out 5W, I found that the resistance was very hot.

Now it's the sitting mat's turn. At first, I was going to repair the cushion and put resistance in it. But the cushion didn't give up his belly so easily.

Eventually, I put the resistance on the chair, and I put the cushion on it.

The basics are as shown in the project below.

In this project, you only need to get the expected weather information through Web Crawling.

Chat GPT API + Youtube Comment + Weather

The firmware was taken from the project above.

Web Crawling

GPT does not currently support real-time data services. So I decided to read it on Naver as WebCrawling.It started implementing in a Python environment that is relatively light and easy to implement.

from bs4 import BeautifulSoup
def getweather() :
    html = requests.get('http://search.naver.com/search.naver?query=수내+날씨')
    soup = BeautifulSoup(html.text, 'html.parser')
    global weather
    weather = ''

    address = "Bundang Sunae"
    weather += address + '*'

    weather_data = soup.find('div', {'class': 'weather_info'})

    # Current Temperature
    temperature = (str(weather_data.find('div', {'class': 'temperature_text'}).text.strip()[5:])[:-1])
    weather += temperature + '*'

    # Weather Status
    weatherStatus = weather_data.find('span', {'class': 'weather before_slash'}).text

    if weatherStatus == '맑음':
        weatherPrint = 'Sunny'
    elif '흐림':
        weatherPrint = 'Cloud'

    weather += weatherPrint

WebCrawling can be done simply with a package called BeautifulSoup.

Let me deal with Crawling briefly.

In the script, temperature was read from temperature_text.

And weather was read in the span class of weather before_slash.

I want to read it in English, but I couldn't find it, so I just hardcoded it...And when you run this, it will look like the following.

It outputs temperature and weather like this.

Operating

The temperature does not rise under very hot temperatures.

Moderate spring weather? The temperature goes up a little bit. Actually, I think it'll be hot if it goes up to here. I need to fix it!

I set it to very cold weather. The temperature rises to 65.7 degrees. My butt will be warm!

It's getting colder... The picture explains the weather outside. It looks so cold!

There's a problem! Even if it gets colder, it should be moderately hot! If it snows a lot, my butt will burn!

Review

I'm using it well, but our company has a heater... If it's cold outside and the office is hot, there's a problem..

For the burning butt

Thanks
