Virtual reality technology has come a long way over the past decade, but there are still some things that could be done to make it even more interactive and engaging. What if virtual reality users could actually feel the ground they walk on rather than just seeing it? A team of students from KAIST in…
When designing and building projects, we probably find ourselves sitting much longer than we should, which poses a problem. Poor posture leads to all kinds of health problems, including back pain, limited circulation, and even headaches. A team of students from Tohoku University in Japan wanted to solve this problem by creating a new type…
In this project we will see how to make a thermometer to measure the temperature in the room with a measuring range from 10 degrees to 35 degrees Celsius and an accuracy of 0.5 degrees. The temperature is displayed on the WS2812 LED bar containing 50 diodes. Characteristic of this thermometer is that in addition…
In this project we will see how to make a smart pot that can show the emotion of a plant. It uses a soil moisture sensor to monitor the state of the soil and then displays an emoticon expression for that moisture level. To carry out this project we first need a plant pot. In…
In this project we see how to build an IOT-based dust monitoring system that can measure surrounding dust, send data over the Internet, and monitor the long-term value graphically. We use a Sharp gp2y1014au0f particle sensor which uses an IR LED and when the particle enters the sensor, the light bounces back to a photodetector….
Voltlog is hacking his car console through the CAN bus. According to the author, for his projects, the available CAN bus interface cards are somewhat lacking. So he designed his own wireless CAN bus hacking and development module called ESP32 CanLite. The project is published as open source and the files can be extracted from…
Peter Balch, reading an IEEE report on speech recognition from the late 1970s, wondered if, with a normal Arduino Nano, it was possible to obtain the results of a computer of the time. Comparing the two tools a Nano has 2 KB of RAM, 32 KB of program ROM and runs at about 10 MIPS…
If you create PCB with SMD components or you are a repairman you surely know how important and convenient a hot air soldering station is. With this project, you will be able to learn how to make a hot air gun controller using Arduino and other common components. This project uses an 858D compatible air…
With this project we will see how to make a solar powered wireless weather station using an ESP32 WiFi module and some common weather sensors. The weather station is fully solar powered, so you don’t need to worry about external power. It can be installed in a remote location without having to lay long cables…
Anyone can learn robotics, but what if there was a practical and inexpensive approach? This is where “Boca” comes in. Boca is a 3D printed open source platform for manufacturers and researchers interested in exploring control theory and Machine Learning. Boca has eight degrees of freedom, thanks to the 8 servo motors, with some great…
There are probably more than a hundred Arduino-based printing machines on the internet with instructions available for making them. What makes this project unique is the built-in camera and screen. Other plotters must be connected to a computer, this works completely independently. The 20fps video shown on the screen makes it easy to capture images…
In this project we see how to build a logic probe, that is a complete, simple and effective instrument that allows you to measure digital logic levels 0 and 1, both in TTL and CMOS technology. The maximum accepted level is 10 volts but CMOS can reach up to 18 volts (however best avoided). To…
Open-Electronics.org is the brainchild of a world leader in hobby electronics Futura Group srl. Open-Electronics.org is devoted to support development, hacking and playing with electronics: we share exciting open projects and create amazing products!
Open-Electronics.org is not just a container of ideas: it is also a web site lead by a team of engineers and geeks who will take part in the discussions and give support.
Our mission is to become a reference Open Source hacking site with ideas and feedback aimed to enrich the community.
