In this blog post, we’ll explore how you can harness the power of Wokwi to simulate embedded system hardware directly in your web browser. Additionally, we’ll delve into the use of their VSCode extension, which enables you to simulate the environment locally for enhanced speed. My quest for simulators began when I realized the time-consuming […]

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.
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.
It is hard to find one good colour-coded pinout drawing for ESP32-S3 so I made one myself.I will update it with for info as I get time. I plan to make more pin out images for other modules too like ESP32-C3 with detailed pin types.
There are several different options to choose from when buying an esp32 Modules. The most common ones I have come across are the following. Espressif / AI Thinker WROOM / WROVER WROOM32U has the smallest footprint among all. WROVER comes with integrated 8MB PSRAM ESPRESSIF ESP32 Modules The footprints are different in size and positioning […]
