  The Hermida Zendrive guitar pedal we will study, assemble and listen to today is a true masterpiece. Many say its sound is close to the Holy Grail of guitar amplification — Dumble Overdrive Special. Other people are more pessimistic in their judgments. Still, the precise response to the picking dynamics, the Voicing tuning options, and the sheer beauty of this overdrive’s sound are simply impossible not to love. But before we study the Lovepedal Zendrive or its copy of the Landtone Phoenix song, or the Aion effects Azimuth dynamic overdrive, we’ll study the evolution of the MOSFET overdrives that finally resulted in the development of this gem. Fulltone OCD Mike Fuller was one of the first to start using MOSFETs instead of diodes to limit the amplified guitar signal in 2004. His Obsessive-Compulsive Drive overdrive-distortion pedal is built on a standard circuit with one dual op amp. The first operational amplifier, X1, amplifies the amplitude of the guitar signal by a factor from 8

The interpretation of the measurement results should be discussed in particular. What should be done after the cable fault location has been searched and the distance to the defect has been measured? First, it is necessary to find the scheme where the cable route is indicated and to estimate approximately which section of the cable the localized defect is located. It is required to make clarifying measurements from the switching points closer to the defect. Other measuring devices, e.g., TDR, should verify the results. Then it is necessary to measure a known distance to the defect on the cable route. It is most convenient to use measuring wheels for this purpose. However, the cable is not laid strictly along the line, so the defect may be quite far away from the postponed point. That is why before searching for the place with a defect on the cable, it is necessary to find the closest switching point to it and measure the defect from it. Another group of "secrets" is related t

  Earlier in the article ( link ), we reviewed the long-distance transmission of HDMI and USB signals over twisted pair cable. We explained the difference between HDMI USB 2.0 and HDMI KVM extenders in terms of practical application. But what if you only need to extend a USB 2.0 interface over a long distance via twisted pair cable? What to do to remotely connect a webcam, speakerphone, or other equipment? Let's look at such extender type using INRIKS EX100USB USB 2.0 extender as an example. Brief feature description The INRIKS EX100USB Extender is a twisted pair USB transmitter and receiver kit. Using CAT6 cable, a transmission distance of up to 490 feet can be achieved. If CAT5e cable is used, up to 330 feet. The extender provides USB 2.0 transmission with a High-Speed (480Mbps) maximum transmission speed. The transmitter must be connected to a signal source (PC, laptop, DVR, and the like). The receiver has four USB ports for connecting various devices. A unique feature of the IN
