Here is a collection of articles describing circuits, experiments and explanation about electronics and radio in general. These articles range from antenna design to PCB circuits, passing by modeling of components. My friend Camoulox will give you in depth details about expert electronics projects wherehas I, F4MVR will present electronics project at my level, i.e beginner.

  • SMD Pixie : 9V Version 0
    This idea came from a discussion on reddit post talking about K6ARK’s micro pixie operation. As I never tried doing anything in SMD I though it would be a great project to learn the basics. The schematic is really simple, I just took an already working schematic from chinese pixies and reimplemented it in Kicad for the PCB.

  • SIMPLIS model for TL494 SMPS controller
    Introduction TL494 is a widely known PWM controller for SMPS. However, it is an old bipolar transistor integrated circuit and only a few SPICE models are available. The major drawback of SPICE for SMPS design is the duration of the simulation. Nevertheless, other simulations approach based on state space modeling exist. Personally, I use SIMPLIS (https://simplis.com/product/simplis). This software… Read more: SIMPLIS model for TL494 SMPS controller
