We teardown and tested in different modes RSP-320-24 power supply from Mean Well. It's a 24-volt power supply with a maximum current of 13.4 amps. The supported mains voltage is from 88 to 264 volts without an additional switch.

In this second part, we'll examine how to transform a successfully prototyped idea into a physical product. Several key aspects need to be reconsidered.

Sometimes, when making your own devices on microcontrollers, there is a need to display huge amounts of information on a display and to use a bigger screen for ease of perception. Unfortunately, there are no ready-made and budget-friendly solutions for this task on the market.

What characteristics are important? What do the characteristics mean? How to measure parameters cheaply?

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

Consider the primary functions of reflectometers, such as automatic detection, searching for crossed pairs, and identifying 'floating' defects.

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.

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.

"PiEBridge" is an extension board for microcomputers similar to the Raspberry Pi (Pi), which is designed to be a helper for the DIY-maker in all his activities...

Critical options for reflectometers: Why is this important, and how do you use it?

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?

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.

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.

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.

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.

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!

How to compare OTDRs from different manufacturers? What is more critical: resolution capability or sensitivity? How to determine the actual range of a device?

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. This is my team's first public project.

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.

How do electronic oscillators work? Who invented them, and when? And how can we apply them? We will talk about all this today.
