#23 Hack Your Electronics: Part 2 - How to make a custom firmware for random electronics

In this video, we will explore the world of sensors on random PCBs and how we can use the existing microcontrollers on them to gather data from these sensors. With the help of ChatGPT, we will learn how to write an I2C driver to interface with these sensors and read data from them.
First, we will go over the basics of sensors and how they work. We will then show you some examples of random PCBs with sensors on them, and explain how to identify the type of sensor and the microcontroller it is connected to.
Next, we will demonstrate how to use ChatGPT to write an I2C driver to interface with the sensor and read data from it. We will provide step-by-step instructions and explain the code in detail.
Finally, we will conclude the video by showing you how to test the sensor and the I2C driver, and how to use the data collected from the sensor, and use bluetooth to push the data. This sensor data can be used for many applications, and I will use it for my Homeassistant setup
This tutorial is perfect for anyone who wants to learn how to work with sensors on random PCBs and how to write an I2C driver with the help of ChatGPT. Whether you are a beginner or an experienced programmer, you will find this tutorial informative and easy to follow.

Thanks for this content. It really helps understanding how you can salvage old electronics and make new fun things out of it.

[@makersfunduck]

Glad you enjoy it:)

[@danielsalloum3006]

Beautiful work. The soothing voice tops it off.

[@makersfunduck]

Glad you like it!

[@jjjjulian]

It was quite hard finding a vid on custom firmware, im really glad i had subbed to u :D

[@makersfunduck]

Awesome, thank you!

[@benvars5889]

bad apple, nice

[@makersfunduck]

Nice catch :)

[@orangeinfotainment620]

Thank you sm

[@mevk1]

Good Stuff

[@makersfunduck]

Thanks :)

could I increase the setting limit by 30° on an air conditioner? I would like to reach 40-50° mechanically it is possible... I don't know how difficult it is to decode the software settings 😅

[@makersfunduck]

well you need to open the controller. If you can tell me what mcu is there, it might be an interesting hack indeed :)

[@electromess4536]

hey man where are you from? Are you from belgium?

[@makersfunduck]

Close by, Netherlands :)

[@jjjjulian]

what app are you using at 6:00

[@makersfunduck]

It is called `nRF Connect` from nordic semi. I would highly recommend it if you are working on bluetooth projects.

@@makersfunduck appreciate it. have a cool day !
