“In this instructable, I will show you how to build wifi flood/water sensor with minimal cost. The entire project costs me less than $8 for parts that I acquire from ebay and my existing spare-parts. In this project, we …
“Cool little Pocket Metal Locator sensitive enough to identify small nails and tacks in wood with four independent search coils and LEDs. This cool little Pocket Metal Locator is sensitive enough to identify small nails and tacks in wood and …
“This project is to build cyclic on-off programmable timer. In this project user can set ON timer and Off time using keys and 7 segment display. Relay is provided as output, where relay will be remained ON for ON time …
“A simple humidity, temperature, and pressure data logger. Components Arduino Pro Mini 5V 16MHz SD card module RTC module with battery RJ11 socket (optional) BMP180 pressure sensor (preferably with a 5V input power option on a breakout board) SHT31-D …
“This is a simple project with idea of creating a resistive touch button that integrates RGB Led. Whenever this button is touched, it will be lighted up and lamps color can be customized. It can be used as a portable …
“Buildroot-based puredata synth, using the nanopi neo core and a CM6206 USB soundcard DESCRIPTION I saw the Organelle, and I really wanted one. They released their software as open source, but not their hardware. I decided I would just figure …
“In the lab, one often needs a repetitive signal of a certain frequency, shape and amplitude. It may be to test an amplifier, check out a circuit, a component or an actuator. Powerful waveform generators are available commercially, but it …
“A buck converter (step-down converter) is a DC-to-DC power converter which steps down voltage (while stepping up current) from its input (supply) to its output (load). It is a class of switched-mode power supply (SMPS) typically containing at …
“In this project I will show you how to create a weather station along with a WiFi sensor station. The sensor station measures local temperature and humidity data and sends it, through WiFi, to the weather station. The weather station …
“In science and in engineering worlds keeping track of temperature aka (movement of the atoms in thermodynamics) is one of the fundamental physical parameters one should consider almost everywhere, starting from cell biology up to hard fuel rocket engines and …
