. We are not talking about QLED The new technology, natural evolution of Quantum Dot that combines them with OLEDs, could soon be marketed by two big names in the sector such as Sony and Panasonic with the first QD-OLED TVs Currently, all OLED panels for TVs are supplied by LG and use W-OLED technology or […]

. Methods for detecting the current in order to find the one that best suits the measurement. Shunt: the simplest method is through a Shunt that we can buy or do it yourself with wire with a very low value or with a power resistance. As we can see in the image above, there are several […]

. Understanding of sampled systems Nyquist's sampling theorem, or more precisely the Nyquist-Shannon theorem, it is a fundamental theoretical principle that governs the design of mixed signal electronic systems. Modern technology as we know it would not exist without analog to digital conversion and digital to analog conversion. In […]

. I made a class D audio amplifier entirely with discrete components, although not the most recommended, the idea of this project is purely educational to understand the operation of a class D amplifier and to mount a small experimental circuit that works correctly with a reduced power powered at 5V This circuit […]

. I recently designed several variable power supplies to test tube amps, actually I designed more than one at the same time with different characteristics. They all have one component in common with the rotator. The rotator is used as an active inductance, that is, it simulates the behavior of an inductance with regard to the impedance trend based on the […]

. This circuit was created to be used to test amplification stages. It produces both square and triangular wave outputs that rise from approx 80 a 730 Hertz in a repeated cycle of approx 6 seconds. Appropriate substitutions of the component value will produce variations in these parameters. Operation is as follows: L’op-amp U1A e i […]

Create a circuit for the precise measurement of low resistances. You already have a DMM to measure resistance, but it can be used with resistances lower than 1Ω? And if so, these low resistive readings are reliable? This project will show you how to make your low resistance meter; use only a handful […]

. Poking even once in all the drawers looking for a 9V battery charged for a multimeter that has shut in time of need (how could it be otherwise?), I thought it would be nice to have a box of these batteries. I have a lot of small rechargeable batteries around, usually with […]
