The BMP380 is aimed at the growing markets of gaming, sports and health management, as well as indoor and outdoor navigation. By measuring barometric pressure, the sensor enables drones, smartphones, tablets, wearables and other mobile devices to accurately determine altitude changes, in both indoor and outdoor environments. Wide range of applications This new BMP380 sensor […]

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 […]

ICStripBoard is a innovative cheap tool to enable rapid prototyping of surface mount integrated circuits (IC’s) and allow their usage in prototype electronics projects. Inline surface mount IC’s come in a Variety of packages which are different sizes and these Printed Circuit Boards (PCB’s) have been designed to accommodate the majority of IC’s. Available in […]

Researchers have demonstrated the high-performance potential of an experimental transistor made of a semiconductor called beta gallium oxide, which could bring new ultra-efficient switches for applications such as the power grid, military ships and aircraft. The semiconductor is promising for next-generation “power electronics,” or devices needed to control the flow of electrical energy in circuits. […]

I finished this laser wall trigger for my HIGH RESOLUTION AND ACCURACY CHRONOGRAPH. The purpose of this device is to generate the trigger start and stop impulses for my chronograph as soon as an object disrupts any of the laser beams. So if I have two laser walls (with one or more laser beams on […]

What’s inside a TTL chip? To find out, I opened up a 74181 ALU chip, took high-resolution die photos, and reverse-engineered the chip.1 Inside I found several types of gates, implemented with interesting circuitry and unusual transistors. The 74181 was a popular chip in the 1970s used to perform calculations in the arithmetic-logic unit (ALU) […]

If you want to take a timelapse with your camera, it may be helpful to use an intervalometer. It is an attachment or facility on a camera that operates the shutter regularly at set intervals over a period, in order to take timelapse series or take pictures after a set delay. Daniel Knezevic had developed […]

Sensing and controlling supply current flow are a fundamental re- quirement in most all electronic systems from battery-operated, portable equipment to mobile or fixed-platform power manage- ment and dc motor control. High-side current-sense amplifiers (or “CSAs”) are useful in these applications especially where power consumption is an important design parameter. New CSA devel- opments offer […]

The Achilles Heel of the Mikroelektronika Hexiwear is its charging: the charging and USB connector are only designed for a limited number of plug-unplug cycles, and it does not have a wireless charging capability like the Apple iWatch. Until now! I have built a DIY wireless charging system for the Hexiwear ? : Wireless Qi […]

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 […]
