<b>Please vote on this project for Instructables Microcontroller Contests. :D</b> If you've invested in cryptocurrency, chances are you're already aware of the extreme volatility involved. Prices can shift overnight, leaving you wondering how much "real" money is still in your wallet. The stock market presents a similar challenge: one minute an investment seems promising, and the next it's worthless. To track these assets and stay up-to-date on their current value, you have two main options. You could rely on spreadsheets that require regular updates or create a custom gadget to monitor values for you – an IoT wallet! For this project, I focused on a Google spreadsheet that tracks my assets and updates their values based on the ticker values retrieved from the internet using Wi-Fi connectivity via ESP32. A summary of these values is then displayed on an OLED screen. To bring everything together, I used 3D printing to create a custom wallet, embedding electronic components within it to create a working IoT wallet prototype. <b>Did you know that a Creality 3D CR10 can be purchased for just $359.99?
