That whole project started a while back with an hackaday article from 2014 in which [Johngineer] build the ‘ChronodeVFD’, a wristwatch made from an old soviet vacuum fluorescent display. It kind of triggered the ‘shut up and take my money’ reflex in me, but as it wasn’t for sale and didn’t have any design details available I

Liquids or other objects appear colored because theyreflect or transmit certain colors and in turn swallow (absorb) others. With a so-called photometer, those colors (wavelengths) can be determined, which are absorbed by liquids. The basic principle is simple: with a LED of a certain color you first shine through a cuvette filled with water or

Description This is a 1×1 inch PCB module with two tiny solar cells, a highly efficient Li-Ion battery charger and with two regulated outputs (3.3V and 1.8V). It harvests enough power from indoor light to power a simple BLE or LoRa sensor. The board has castellated vias so it can be surface mount soldered onto

Makers, developers and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published to the official Arduino blog, featuring Karl Kristian Torp’s palm-sized Tiny V/A. The Arduino Nano based project takes input from the power supply via a female barrel jack connector. This supplies

Coming soon to Crowd Supply is the ultimate USB-UART converter. μArt is a device that offers safe and reliable USB-to UART conversion. The voltage levels, electric potentials, and communication speeds are no longer a concern, and it can be used for data exchange or for Programming Arduino or ESP. μArt was designed for enthusiasts and

Hello, fellow Makers! In this instructable, I will be discussing my newest and most versatile tool for edcuation: the E.M.F. Meter. This instructable will be covering a lot of steps involving Arduino and Raspberry Pi software. Although resources will be provided, please make sure you have some familiarity with these softwares before tackling this project.

Tektronix, a US-based company, has introduced two new Keithley 6½-digit models to its line of Digital Multimeters (DMMs) and data-acquisition systems: The new DMM6500 DMM and also the new DAQ6510 data-acquisition system. The company has also upgraded their Kickstart measurement software to version 2.0. Keithley has long been a dominant provider in the 6½-digit DMM market. With the DMM6500 and DAQ6510, the company looks forward

Hi guys, welcome to today’s tutorial. Today we will look at how to use a hall effect sensor with Arduino. A hall effect sensor is a sensor that varies its output based on the presence or absence of a magnetic field. This means that the output signal produced by a Hall effect sensor is a
