Don’t let a clogged drain slow you down!Coming back from our vacation, me and my wife were surprised by the water covering the floor of our apartment, and we found out it’s not even clean water, it’s drain everywhere. After clearing the drain and cleaning the floor, I had this question: why don’t we have …
The STM1831 is a voltage detector with very low current consumption. It monitors a voltage on a separate input pin (VSEN), which is fully functional even if the monitored voltage goes down to 0 V. In addition, the delay of the output can be adjusted by an external capacitor. Key Features Voltage monitored on separate …

A while back I saw an EMF (Electromagnetic Field) Detector at makezine.com that used a led bargraph. I decided to modify it to use a 7-Segment LED Display! Here’s my project. Sorry I don’t have any pictures of it in use. Hopefully I can post some soon. Credit goes to Aaron ALAI for the original …
Let’s create a simple Gas Detector connectable to WiFi. The gadget would offer: web UI including gauges for LPG, CO, Smoke simple data handler returning values in JSON capable of regularly sending data to ThingSpeak server and obviously triggering laud alarm if threshold of dangerous concentrations exceeded. We would need following components: NodeMCU with ESP8266 …
One of the challenges involved in recycling plastic is determining the specific type of plastic a given item is actually made of. To keep up with demand, large scale recycling centers rely on various automated systems to separate different types of plastic from a stream of incoming material. But in less technologically advanced parts of the world, …

Rev 2.5 – tidied up the 3D printed parts and updated the plug connector to a common PCB unit. Rev 2 – ultrasonic “button” replaces manual push-button. Pushing a button is so old fashion, particularly when I’m already using an Ultrasonic sensor. Why not use an ultrasonic sensor to activate the can level detector! Rev …
Hi guys, welcome to today’s tutorial. In this tutorial we will look at how to use the TCS230 color sensor with Arduino. To demonstrate the ability of the color sensor, we will build a color detector system capable of detecting the color in front of the sensor and displaying that color on a TFT Display. …

At any given moment, the Earth’s atmosphere is showered with high-energy cosmic rays that have been blasted from supernovae and other astrophysical phenomena far beyond the Solar System. When cosmic rays collide with the Earth’s atmosphere, they decay into muons — charged particles that are slightly heavier than an electron. Muons last only fractions of …
