FOVEA is a wearable embedded analyzer — a multimeter targeted at embedded electronics with wrist-worn convenience. FOVEA, their wearable embedded analyzer does a few primary things to make embedded work easier: (a) It moves the multimeter display to a location that’s much closer to where the probes are being held, and also with almost the […]

Keysight 34465A & 34470A DMMs offer unprecedented levels of accuracy, speed and resolution. They can measure very low current down to a 1 μA range, enabling their use on very low power devices. The ability to auto-calibrate during the measurement allows the 34465A and 34470A to maintain a calibrated measurement while the instrument may be

In electronics, a device is said to be a latching device if it maintains any particular fixed state even after removal of the input signal. The same also applies for electronic/electromechanical relays. Basically the electromechanical relays that are used today are of two types: 1. Non-Latching Relay : These relays are most widely used where

Today I will show a very simple ionization chamber that can detect radioactivity. I was able to detect with it ionizing radiation from a smoke detector (Am241 isotope). It’s also immune to electromagnetic interference (EMI) due to a good shielding. This device doesn’t explicitly use any power supply. It’s connected to a multimeter set to

The purpose of this project was to design a functioning digital meter to measure voltage, current, and resistance to a known accuracy. The project involved the integration of hardware and software to take an input measurement signal from a pair of high and low leads that was then displayed on an LCD per the rotary

Troubleshooting iPhone problems can be a daunting task sometimes considering how complicated they are. It’s easy to overlook the simple things and on occasion you may replace parts that don’t need replacing. Batteries are no exception. I have seen technicians often replace batteries when they may not necessarily need to be or ignore the fact

This tutorial is going to teach you the basics on using Flux Sensor of 2.2 inches. Step 1: Introduction Description: It is a flex sensor which is 2.2 inches in length. This sensor works by bending the sensor itself. As the sensor is being flexed or bent, the resistance across the sensor increases. The greater

Learn how to make an LED matrix controlled by an Arduino. Scroll down further for step by step photos and more details. You’ll need the following parts: a prototyping board, (2) 8 pin headers, (8) 200 ohm resistors and (64) red LED bulbs. Arrange the LEDs in the board according to the design you’ve chosen: either

Most projects include at least one LED. Before soldering the LED, how can you determine if the color and brightness meets your needs? After that, how do you calculate the correct value resistor? Many years ago, I built a handy compact LED testing tool based on the LM317L adjustable current regulator. (You’ll definitely want to

It has been a while since i posted my Tinker Rule which i made during college days. I received a few requests for the ready to etch pdf which helped me gauge if this seemed to be useful to people. The response was somewhat positive and so, i decided to put in some extra effort
