Author

Hello everyone,

My name is Krakkus, the author behind this website and the YouTube channel with the same name.

I am 40+ years old and have been employed as a IT specialist for a couple of companies in the past two decades.

As a hobby I have done programming for most of my life in all the major languages including assembly but not java. Done everything from poker-bots to neural networks and 3D graphics when that was still done in CPU.

Now my hobby is partly shifting over into electronics, but I am taking my programmers view on things with me, that helps me a lot.

Both pictures are more than a year old, but still pretty accurate, I like them.

My other two hobbies are sports (running&fitness) and my chickens who run around the house.

    How to make an op-amp output PWM with duty-cycle control?

    We can use a generic op-amp like the LM4562NA. We build an oscillator from the first op-amp in the IC. This produces a triangle-wave. We feed this wave into the second op-amp....

    How does an op-amp work?

    Op-amp is short for operational-amplifier. You can use it as a comparator, buffer a signal, or amplify a signal. These are some op-amps I have; they are the LM358 and the LM4562....
