FBD PLC Programming Using The Siemens TIA Portal Using the Siemens TIA Portal and function block diagram programming, I created an atmosphere control system that simulated an apple storage system. The program was integrated with a development board by Kaftan. The program checks for 4 input switches and sets a status flag to start the…
TDA7297 Class AB Audio Amplifier PCB Design – Autodesk Fusion 360 Using Fusion 360, I created a Class AB amplifier with the TDA7297 at the heart of the amplifier. The circuit boosts a low power audio signal to one strong enough to be driven by headphones or speakers. The TDA7297 has a good power output…
WiFi Car Battery Voltage Monitor – Arduino ESP8266 As an extension from the temperature and humidity sensor for my car, I then used a voltage divider resistor network between the microcontroller and my car’s fuse box. This gave an accurate reading of my batteries voltage. This information was sent over WiFi to my phone. It…
Elegoo Arduino Starter Kit – 18 Videos Tutorial Creation Elegoo, a Chinese company, created a starter kit Arduino clone. The kit is fantastic but only comes with PDF tutorials that (in my opinion) were sub-par. I decided to create a series of video tutorials, whereby I built each circuit, programmed it to work correctly and…
My YouTube Channel I started a YouTube channel in my first year on university to document my studies and projects. The channel has 250+ videos and 2500+ subscribers, amassing over 200,000 views. The theme of the channel is DIY electronics. « Prev1 / 35Next »« Prev1 / 35Next »
STM32 Nucleo Embedded Systems Clock & Temperature Project I created a hardware system using the STM32 Nucleo board. The STM32 was mounted on a glass plate, alongside an LCD and a breadboard. The breadboard includes a buzzer, buttons and a DS1631 temperature sensing IC. The system can display the current temperature on the LCD, displaying…
1 Stage Charge Controller Circuit – PCB Design & Print – KiCad I designed a simple 1-stage charge controller circuit schematic and PCB. This was then manufactured in China using JLC PCB and then the circuit soldered and tested by myself. The circuit uses a relay to disconnect the solar panel from the circuit, when…
Stamp CAD Design & 3D Printed – Fusion 360 Using Autodesk’s Fusion 360, I created a two-component model. I then 3D printed the model using ‘Slic3r’ software and an Ender 3 printer. This project involved the following skills and techniques; Fusion 360 Software Computer-aided design (CAD) 3D Printing Slicer Software
For this project I used a police strobe light electronics kit from AliExpress. The kit uses a 555 timer and a decade counter to create pulses that control the voltage between the red & blue LEDs. The kit didn’t work when initially soldered as there was a fundamental problem with the circuit, whereby the 9V…
https://www.youtube.com/watch?v=_FmjrSDuWMM&t=1s In this project I decided to install a temperature & humidity sensor in my car. I was having a problem throughout winter, not knowing if my car’s windscreen was frozen. So I used an ESP8266 hard-wired into my fuse box using a 12V-5V regulator, to detect my windscreens temperature and humidity. I then sent…
