I’ve been working on a project that needed an audio amp, so I went with the LTK8002D. Along the way, I ended up designing a quick test PCB to try things out before moving on to the final version. Since Read more…
I recently got some tiny LCD screens that have 3 digits with 7 segments, and I’ve been playing around with them to understand how they work better. The first thing I noticed compared to 7-segment LED displays is that to Read more…
In this project, I used the RSSI value (Received Signal Strength Indicator) as a measure of distance between the transmitter and the receiver, using the ESPNOW wireless protocol. The transmitter is an ESP8266 with the following code: It sends a Read more…
In this project, I developed a simulated parking monitoring system using two ESP8266 as the hosts devices. The ESP8266 is responsible for counting the number of cars in a parking lot and transmitting this information to an InfluxDB database and Read more…
This project is about trying to make a robot that looks like a character from a video game called World of Warcraft. This robot is obtainable in the game through the engineering profession. Since I liked the aesthetics, I think Read more…
In this project, my goal was to create an alarm similar to the one used by one of the main characters in the series Silicon Valley, known as Gilfoyle. He used an alarm that incorporates the song ‘you suffer’ by Read more…
In this project, the following components have been used: Beforehand, RetroPie has been installed on the Raspberry Pi, providing a collection of emulators for a wide range of gaming consoles. Next comes the more tedious task: soldering all the wires. Read more…
For the project, we will need: The idea is to attach the joystick lever to the clip or any other suitable item. The most important part of the connection is to use the correct pin of the NodeMCU, which is Read more…
The goal was to, having already manually configured server with its respective IVR menus, voicemail, MySQL database (with OBDCconnector), connection to another PBX, group calls, music on hold, call forwarding, and TTS system, implement an emergency call button that would Read more…
The goal of this project was to learn how to stream live data from a sensor using a NodeMCU ESP8266, which enables us to create a web server. While the basic part involves using the right library to create the Read more…
