Universal VFO 10 KHz-160 MHz with Retro Analog Scale (variable frequency oscillator)
Pavleski Nov 19,2022
  A variable frequency oscillator (VFO) is an oscillator whose frequency can be tuned (i.e., varied) over some range. It is a necessary component in any tunable radio transmitter or receiver, and controls the frequency to which the radio is tuned. This time I will show you how to make a VFO that covers the range from 100 KHz to 160 MHz and uses a minimum number of components. The selected frequency is displayed on a beautifully designed retro scale in the style of ham radios from ...

ARLOK - Arduino Robot (Rev.1)
CyB3rn0id at Settorezero.com Nov 18,2022
Arlok is a simple educational (STEM) Robot based on Arduino Uno with parts printed in 3D and all easy-available components. 3D-printed parts are big, easy to manipulate and printed even by cheap 3D-printers. Arlok is highly customizable: there are many types of wheels and tires (to be 3d-printed in TPU or commercial types), 2 types of ultrasonic sensor pillars, 3 types of pillars for various kinds of power buttons, various type of powering methods. Arlok is cheap, cute and easy to assemble and p...

Dual Motor Driver as Robot Base
Arnov sharma Nov 17,2022
Hey everyone, what's up?So here's something awesome, a Microrobot Base that is equipped with a Few FETs to make an H-Bridge for driving two Motors.These FETs are used for driving small gear micromotors with a 3.7V Li-ion cell.Apparently, common motor drivers like L293D work with a minimum voltage of 4.5V to 36V, so it wouldn't work with our current setup, and we need to increase the battery voltage from a single 3.7V cells to a battery pack composed of two or three cells in series. Ele...
