Introduction I’ve for some time now wanted to do more RF design. Although I have taken some RF design courses, I haven’t actually made a single RF design before. But you can’t learn without doing and inspired by the MIT coffee can radar designed by Gregory Charvat, I figured that building a radar should be […]
PremoBoard can be controlled by any system via the USB port: it is an expansion board designed for (but not limited to) cubieboard (A10 or A20). PremoBoard is a expansion board featuring the following: – 4 USB 2.0 – 2 LAN 10/100 – 2 WIFI (OPTIONAL) For more detail: PremoBoard
… and will prevent to spread there, where you don´t want to. Fluxes in pen Stannol series Mini Fluxer belong to the invaluable helpers of every electro-technician. How could I work without a flux so far? That´s a probable question of probably everyone, who once tried action of a solder flux. In a common

This article is about interfacing gyroscope to arduino. Gyroscope is a device used for measuring the angular velocity in the three axes. It works under the concepts of angular momentum and can be used to determine the orientation of an object. Typical applications of gyroscope includes missile guidance, flight control, smart phones, game station joy
The spectrum analyzer has always been a vital tool for the EMC engineer. Until the last few years, these instruments have been rather large and heavy desktop instruments, weighing up to 60 pounds, or more. With the breakthroughs in components used for wireless technology, the size and weight of these instruments has decreased dramatically. This

Hey, sorry everyone, I know it’s been a while. But I hope this post will make up for that! Anyone who has done embedded programming knows that an easy way for microcontrollers (like arduino) to connect to a PC is through a serial connection. Unfortunately, not many computers have a serial port these days, and
The Zeta is a minimal Z80 toggle-switch computer. It has a Zilog Z80 microprocessor, 256 bytes of RAM and the only interface is the front panel which directly sets and reads the address and data buses. There is a video of it executing Euclid’s algorithm: https://www.youtube.com/watch?v=0GmY_UrbXnA At the moment, there is only one real source

The LTC®3807 is a high performance step-down switching regulator DC/DC controller that drives an all N-channel synchronous power MOSFET stage. A constant frequency current mode architecture allows a phase-lockable frequency of up to 750kHz. The 50μA no-load quiescent current extends operating run time in battery-powered systems. OPTI-LOOP® compensation allows the transient response to be optimized
When we first encountered the offspring of this Digi-Key/Mentor CAD collaboration, it was still in beta, and the pricing model was unclear. Now that it’s here for real, let’s take a quick look. For more detail: Mentor meets Digi-Key, low-cost CAD results
