I bought this VGA signal generator module years ago from some web shop in China. It is designed to easily test your VGA monitor(s) (VGA/SVGA/XGA) with this handy tool. It can be also used as a general purpose video signal source when testing other video equipment that take in VGA signal (like video switchers, converters, →
Chris Petrich Warns “Almost All” DS18B20 Sensors Not Bought From Authorized Distributors Are Fake https://www.hackster.io/news/chris-petrich-warns-almost-all-ds18b20-sensors-not-bought-from-authorized-distributors-are-fake-afcc0a8befc5 A test purchase of 1,000 sensors from 70 different sellers showed the majority to be counterfeits of extremely variable performance. →
When gamer kids generation really hits audio engineering there will be huge market for this kind of RGB light gadgets? Neutrik etherCON® and XLR Halo Connectors are chassis connectors that incorporate a halo light ring and assymmetric ESD safe push tab. This design allow for standard XLR connector cutouts in the chassis without the need →
The Tektronix TDS220 is a portable two-channel digital scope with 1 GS/s sampling rate and 100 MHz bandwidth. This is part of TDS200 oscilloscope series, that was released in 1997. Sister models include TDS210 (60 MHz dual-channel) and TDS224 (100 MHz quad-channel). Tektronix TDS 210 and TDS 220 Digital Real-Time oscilloscopes offered at them time →
I got an old HP mixed signal oscilloscope HP54645D. This is over 20 years old test instrument with 7″ CRT display. The 54645D is a 100 MHz, 2+16 channel Mixed Signal Oscilloscope from Agilent. Measure voltage or current signals over time in an electronic circuit or component to display amplitude, frequency, rise time, etc. Applications →
Oscilloscope History and Milestones http://www.oscopes.info/background/2265-oscilloscope-milestones Oscilloscopes have been invented in the 1920s. Up to now this instrument encountered many innovations. Today the main players are Keysight, Tektronix and Teledyne LeCroy.

The Tektronix 2235 is a 100 MHz dual-trace, dual-timebase portable scope. Tektronix 2235 has two channels and delayed sweep. This is still a pretty decent analogue oscilloscope (if you are looking for an analogue oscilloscope) with Large, Bright CRT screen. This oscilloscope has the U shaped handle that has detents which allow it to double →
The transistor, the component that created a revolution in modern, miniaturized electronics, turns 75 this week. The first transistor, developed by Walter Brattain and John Bardeen, consisted of the semiconductor germanium, gold, a crude spring and a metal base.

Star quad cable is a type of balanced audio cable that specializes in reducing electromagnetic interference. Quad cable is better at rejecting external noise than an equivalent single pair cable. Star-quad cable is a four-conductor cable that has a special quadrupole geometry which provides magnetic immunity when used in a balanced line. Four conductors are →
DC signals also affect the movement of the speaker cone which may result in a reduction of audio quality, although low level DC doesn’t damage the speaker. If you were to apply more than a little DC power to speakers, this will cause the voice coil to heat up significantly, which would likely cause damage. →
