You may have a 3D printer or other “digital” tools like a laser engraver or CNC router, but what if you want to work with Styrofoam? As How To Mechatronics demonstrates in his latest project, many of the same techniques used there can be implemented to make your own Arduino-powered hot wire cutter. This build…
It seems that writer Dean R. Koontz was right and Coronavirus pandemic is spreading at high speed. Using airports method, scan your home visitors body temperature as soon as they ring the bell using IR remote temperature. If body temperature is normal ring the bell, otherwise an alarm will appear. Everything that has mass emits energy…
https://youtu.be/IXAx29LAVCs Maintaining hand hygiene and washing hands are the most important personal hygiene measures to prevent the new coronavirus. In daily life, we inevitably touch various public facilities, such as the switch of the company’s water dispenser. Since drinking water is everyone’s daily and you need to touch the switch of the dispenser…
“Twinkle, Twinkle, Little Star”? How we wonder why you’d resort to singing a ditty to time your handwashing when you can use your social isolation time to build a touch-free electronic handwash timer that the kids — and you — might actually use. Over the last few months, pretty much everyone on the planet has been…
I had the opportunity to work with Noe Ruiz from Adafruit to write some CircuitPython code for the PyPortal Titano Weather Station. The PyPortal boards have a SAMD51 along with an ESP32 co-processor, which allows them to connect to Wi-Fi and run CircuitPython. This project displays a live feed of the current weather for your…
It’s one thing to be able to transcribe music from a flute, and it’s another to be able to make a flute play pre-written music. The latter is what [Abhilash Patel] decided to pursue in the flute player machine, an Arduino-based project that uses an air flow mechanism and PVC pipes to control the notes…
Our heart beats 115200 times a day, it is such a fine machine that does not stop during our lives. However, not many people have the advantage to have this machine in good conditions. Many factors of daily life can permanently affect cardiac function. Factors such as: Sedentarism. Diet full of Salt, saturated fats…
Andy Bradford has been wanting to upgrade their heating system for a some time – but their house is rented. Damaging the house would cause them to lose their security deposit, “so the whole system must do no damage, be made only of removable parts and be installed without modifying any of the existing…
Numerical control(also computer numerical control, and commonly called CNC) is the automated control of machining tools (drills, boring tools, lathes) and 3D printers by means of a computer. A CNC machine processes a piece of material (metal, plastic, wood, ceramic, or composite) to meet specifications by following a coded programmed instruction and without a manual…
Often when designing Data acquisition systems, such as plant health monitoring in which case, the sensors are placed on-site, knowing the weather conditions may help in predicting the behaviour of other data and changes in physical requirements, if any. The project involves the design of an IoT based solution to monitor the data obtained from…
Using a relay with the ESP32 is a great way to control AC household appliances remotely. This tutorial explains how to control a relay module with the ESP32. We’ll take a look at how a relay module works, how to connect the relay to the ESP32 and build a web server to control a…
The Global Positioning System (GPS), originally NAVSTAR GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Air Force. It is a global navigation satellite system (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an…
