Variable 400V DC power supply – part I.

Variable 400V DC power supply – part I.

Experimentation with vacuum tubes requires a high voltage power supply, typically 200-400V DC. Most hobby labs are not equipped with such a device. This step-up converter allows you to boost up your benchtop 0-24V variable DC power supply to a high voltage power supply.
High resolution PWM signal generation for RC servos with STM32

High resolution PWM signal generation for RC servos with STM32

Currently, I'm building an RC transmitter/receiver based on the SX1280 RF chip. One of the goal for the project is that I want 12 bit servo resolution from the sticks all away down to the servos. Partly because modern digital servos have 12 bit resolution secondly a high-end transmitter is using 12 bits anyway. I…
