DIY variable tuning capacitor

For those who enjoy building radio projects, you may have noticed that variable capacitors are not as available as they once were. There was a time when all radio receivers contained at least one, but with the arrival of the varicap diode and frequency synthesizer, the traditional tuning capacitor is difficult to find. With a range of 5 pF to 27 pF, this multi-turn capacitor can be constructed using only six items. View the step by step guide

Project: Raspberry Pi CNC – and for remote control of your CNC .

#RaspberryPi #CNC Controller is board which can control stepper motors for 3 axis devices (X, Y, Z). It uses Pololu A4988/DRV8825 drivers and can control 2 stepper motors for X axis, 2 stepper motors for Y axis and one stepper motor for Z axis.

Brain of this board is #Arduino Nano with #GRBL firmware. Board can be used separately (controlled by USB on Arduino) or can be used as hat on Raspberry Pi and controlled by UART.
