Introduction Flyback converters are widely used in isolated DC/DC applications because of their relative simplicity and low cost compared to alternative isolated topologies. Even so, designing a traditional flyback is not easy—the transformer requires careful design, and loop compensation is complicated by the well known right-half plane (RHP) zero and the propagation delay of the […]
Long term reliable contact without interference, creaking and hum, moreover in a beautiful coat – these are the Neutrik / Rean connectors. Connectors have in general one interesting feature – there are many similar or almost the same connectors on the market. Audio connectors are not exception in this. Even though they look the same,

An black and white monitor needs to improve and repair from about 1990-th. The repair of device was not difficult but it caused troubles for the testing and setting of the monitor. We have a pattern TV generator, but this instrument are produce on the composite video signal for monitor. Unfortunately this monitor is demand
If you need to produce extremely fast pulses in response to an input and trigger, such as for sampling applications, the predictably programmable short-time-interval generator has broad uses. The circuit of Figure 1, built around a quad high-speed comparator and a high-speed gate, has settable 0- to 10 ns output width with 520 ps,
Simple nanosecond-width pulse generator provides high performance Read More »
In this instructable, I’ll go over what a printed circuit board is, where they are used, and the basics of how to make one yourself. So sit back, strap in, and enjoy learning about this very important and interesting method of making electronics! Note: this is an introductory guide. I’m sure that there is a
Researchers Superconduct at 140 Degrees Lasers align lattice for pulses of superconductivity R. Colin Johnson 12/15/2014 07:15 PM EST 8 comments PORTLAND, Ore. — Superconductors are heating up. A group of international scientists working with the National Accelerator Laboratory in Menlo Park, Calif., have discovered lasers that can create conditions for superconductivity at temperatures as
So, you’re an electronics hobbyist and want a 1GHz* active probe, or a professional and tired of blowing your 2000$+ active probe in sketchy circuits when all you wanted to know are the whereabouts of some RF-signal? Then stay with me!! This Instructable will show you how to build a 1GHz* Fet-based Active Probe, the
