DC-DC converters are widely used components that convert DC power from one voltage to another, producing a regulated output voltage. These devices are used in many electronic products, including laptops, mobile phones, and instrumentation. Like any device, DC-DC converters need to be characterized by manufacturers and by engineers evaluating them for a design. Given the […]

Company Quectel brings to a market its first high-speed module EC20 which you can try yourself. More than fifty developers worked for over ten months on this module We´d like to share with you its parameters, as well as hints, which can make your work with this module easier – this is our biggest bonus […]

Summary This project is an automatic pet feeding system using NXP Semiconductors’ PCA8565. The PCA8565 is a CMOS1 real time clock and calendar optimized for low power consumption. A programmable clock output, interrupt output and voltage-low detector are also provided. All address and data are transferred serially via a two-line bidirectional I2C-bus with a maximum […]

n our portfolio can be found quality knobs from company Cliff suitable for a wide range of potentiometers and encodersA device with excellent specification, quality components used, …., but a one step is still missing to reach a great overall impression – it is to use a quality and aesthetic control components. Probably you´ll agree, […]

  Have you been using float or double variables to perform mathematical operations on embedded systems without a Floating-Point Unit (FPU)? You are doing it wrong! That’s incredibly inefficient. Use fixed-point representation instead. An FPU is an hardware block specially designed to carry on arithmetic operations on floating point numbers. Even though the C/C++ code may work without […]

Lithium Batteries are indispensable. I have a few project like my own DIY Badge [Post Soon] or a Light Wand for Light Photography and an in-progress Mobile Rejuvenator which use lithium batteries ,usually those re-purposed ones that are sold in Local markets for Solar Lanterns with a capacity of 1100mAh. The lazy me used to […]

While I waited for the Mini 7-Segment Clock v3 PCBs to arrive, I got to work on designing an enclosure. First, I exported the PCB from EAGLE to SketchUp. I then assembled a complete 3D model with all the necessary components. With the 3D model complete, I could then design an enclosure to house the […]

Maybe it´s the right time for you to also consider usage of OLED displays in your applications. The most advanced display technology – OLED, goes ahead into many industrial products thanks to its advantages. From a certain point of view exactly the industrial environment properly checks features of displays and especially in critical applications extreme […]

What does the „Tripple Lock“ mean? As already the name says, it is a triple locking – protection against disconnection. The basic and the most important is a sophisticated design with exactly mating parts and a reliable lock. Audible click is a discreet but very useful feature contributing to a correct connector assembly. Optional protections […]

The dB (decibel) is one of the most common units in engineering, yet also one of the most confusing, especially when it comes to manipulating S-parameters. Here is how not to be confused. The Bel is a fundamentally new unit, which was originally established in 1928 by The Bell System to describe sound levels. This […]
