PiEBridge has built-in programmable power supply for external/target devices and two connectors IDC6 and IDC10. More details in the post.

Continue reading →To make a good AM radio, one transistor is enough. It can amplify both radio frequency and audio signal. It is called a reflex circuit, and it shows excellent results.
Continue reading →We teardown and tested in different modes LRS-150-24 power supply from Mean Well. It's a 150W single-output enclosed-type power supply with a 1 3/16" low-profile design. Adopting the input of 115VAC, the power supply provides an output voltage line of 24V DC.

Continue reading →It was the very first all-transistor commercial radio in the United States and in the world. How much have circuits and enclosure designs changed in 69 years?
Continue reading →Why use HDMI over IP in some cases? The image quality is noticeably worse than a classic HDMI twisted-pair extender. Let's see a few examples and answer this together.
Continue reading →The noise filtering function - how to use it, when it helps and when it interferes with measurements. An important parameter is the velocity of propagation (VoP) - how it affects the measurement accuracy and how it can be determined experimentally if its value is unknown.
Continue reading →What is tube sound? How is it different from the transistor one?How do long radio tubes differ from short ones? Today we will build a small tube amplifier powered by 12 volts AC. And with its help, we will hear the answers to these questions and see them on the oscilloscope screen.
Continue reading →We have many years of experience in developing electronic devices for various customers. When we complete a non-standard task, we often explore new methods and ways to achieve the required result. By accumulating this knowledge, we create solutions to simplify the design and creation of devices. It's time to share some of our solutions with the community now.
Continue reading →On the oscilloscope screen you can see signal distortions and use them to determine the health of the circuit. But where do you get the reference signal? - A signal generator will help!
Continue reading →How to compare OTDRs from different manufacturers? What is more critical: resolution capability or sensitivity? How to determine the actual range of a device?

This is my team's first public project.
Continue reading →Earlier, we'd looked into the case of controlling one DVR from two remote rooms. The 4K HDMI KVM twisted-pair extender INRIKS EX4076KVM was the best device for the job. We decided to make a more detailed review of it and test it properly.
Continue reading →How do electronic oscillators work? Who invented them, and when? And how can we apply them? We will talk about all this today.
Continue reading →What determines the accuracy and range of defect detection? What is better: short/long or single/multi-pulses? Case: one reflectometer, but different types of cables.
Continue reading →Today we will assemble a small medium wave radio transmitter with which you can check and configure AM radio receivers, as well as listen to music through them if you connect an MP3 player or smartphone to it.
Continue reading →What if you need to connect two different remote workstations for CCTV operators so that every one of them can see the image from the DVR and control it? Let's try to solve this problem in practice using HDMI KVM extenders over twisted pair and see if it works out.
Continue reading →My first impression was that I had finally assembled the best overdrive in my entire life. For the first time, a cheap Squier Bullet Mustang electric guitar with stock humbuckers sounded equally good with all the cabinets I usually simulate and switch between when testing a new pedal.
