Cheap DIY Stream deck alternative

In this blog post, I share my experience of building a cheap DIY Stream deck alternative using FreeTouchDeck, an open-source project maintained by Dustin Watts. The project saved me hours of writing code and was a ready-to-use project that only required compatible hardware. I used a 2.4in TFT LCD using ILI9341 driver with resistive touch, an ESP32-WROOM-32 bare module, an ESP32 breakout board, and a CH340 Programmer. After some challenges with soldering and programming, the Stream deck alternative was ready to use, and I even used the box that the LCD came in as an enclosure.

DIY ECG/EKG Electrocardiogram

I needed an ECG but faced long wait times to see a specialist. I decided to build a DIY ECG device using the AD8232 ECG module and an ESP32-S3 dev module with an LCD screen. After some tinkering, I was able to build a device that read ECG data and displayed it on a screen. I also added a feature to detect the frequency of the ECG data and calculate heart rate via the RR interval in realtime on a browser through websocket.
