There are several ways to produce a negative voltage from a positive voltage source, including using a transformer or two inductors and/or multiple switches. However, none are as easy as using the LTC3863, which is elegant in its simplicity, has superior efficiency at light loads and reduces parts count compared to alternative solutions. Advanced Controller […]
[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will automatically calculate the necessary series resistor. If for example the LED is destined for 14 V, this device will not only show
LED TESTER ALSO CALCULATES RESISTOR FOR TARGET VOLTAGE Continue Reading
Spare a moment’s pity for the process engineer, whose job it is to keep industrial automation running no matter what. These poor souls seem to be forever on call, fielding panicked requests to come to the factory floor whenever the line goes down. Day or night, weekends, vacations, whatever — when it breaks, the process

The magnetic compass has been a crucial navigational tool for around a thousand years or so, perhaps longer. While classical versions still work perfectly well, you can now get digital magnetometers that work in much the same way. [mircemk] decided to whip up a digital compass to demonstrate the value of these parts. The build uses

Why another spot welder project? Building a spot welder is one of the (arguably few) cases in which you can build something for a fraction of the price of the commercial version with comparable quality. And even if build-before-buy were not a winning strategy, it is a lot of fun! So I decided to embark

Ultra-compact high reliability design eliminates heat generation, improving safety and energy savings in industrial equipment ROHM has recently announced the availability of the industry’s smallest contactless current sensor, the BM14270MUV-LB. It achieves minimum power loss (no heat generation) in an ultra-compact size, making it ideal for industrial equipment and consumer devices that detect operating conditions via
INDUSTRY’S SMALLEST CONTACTLESS CURRENT SENSOR FEATURING MINIMUM POWER LOSS Continue Reading
The ZED-F9P positioning module features the new u-blox F9 receiver platform, which provides multi-band GNSS to high volume industrial applications in a compact form factor. ZED-F9P is a multi-band GNSS module with integrated u-blox multi-band RTK technology for centimeter-level accuracy. The module enables precise navigation and automation of moving industrial machinery by means of a small, surface mounted module. The ZED-F9P

The PNP transistor is a mystery to many. But it doesn’t have to be. If you want to design circuits with transistors, it’s really worth knowing about this type of transistor. For example: Want to automatically turn on a light when it gets dark? The PNP transistor will make this easy for you. In my
PNP Transistor – How Does It Work? Continue Reading
This Design Idea is a solid state relay (SSR) which uses a triac to switch AC loads at high current. There are plenty of simple SSR circuits available, but this may be the simplest circuit that achieves turn-on and turn-off only when the AC line voltage is near zero. Figure 1 AC SSR schematic with
Simple SSR has zero-cross on/off switching Continue Reading
Introduction: Hi every one… Every makers need a software to design PCB board for their prototype. So, we use many design software like Eagle cad, Fritzing, ABC PCB,PCB123, etc… In most of them we can jut design PCB and print and make PCB. So that we can’t get any idea about How is the PCB.
