I had the MPU6050 module on my shelf for a long time before I finally decided to open it. I was really excited to do an Airmouse project with ESP32 but procrastination has been my friend for all this time. I finally decided to open the static safe seal and solder the header pins to […]
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 recently bought a less than 5 Euros cheap Soldering Iron which I decided to make smart by adding a control circuit to it. The project requires the following components The project had 3 main stages Budget The total cost for the project was The total budget came to 13.5 Euros, which is cheap. 😉
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.

I had asked the question on Stack exchange here and had answered myself with a fix after I found out how to fix it. Summary of the issue I have ILI9341 320x240px TFT LCD screen which I am using with an ESP32-S3-wroom-1 module. I have tested with TFT_eSPI and it works fine, but when using LVGL, I […]
