Introduction There is a variety of applications where a mechanical potentiometer is part of a user control interface. These mechanical potentiometers can be changed to more updated and reliable encoder-controlled elements and digital rheostats, being components that change the electrical parameters of the signal. In this article, we used GreenPAK™ SLG47004. It is a great choice […]

1. Introduction Statement of Purpose Our project selection stems from the recognition that power supplies represent a crucial and costly aspect of any electrical project. In an industrial context, numerous product test setups demand precision voltage references, but the acquired supplies often exceed the required wattage and come at a higher cost. Conversely, for hobbyists

This is a precision, low power oscillator that occupies very little space. The oscillator frequency is adjustable using an onboard multi-turn trimmer potentiometer. The output of the circuit is very accurate and has a 1.5% frequency error. The project operates with a single 5V power supply and provides a rail-to-rail, 50% duty cycle square wave output. The CMOS

Introduction The goal of this project is to develop an electrooculography (EOG) system that can record potentials across a user’s eyes, and use the resulting signal to control a simple video game. An electrooculograph is a device that measures the standing potential across the human eye. In this project, we will use silver-plated electrodes to

We designed, constructed and tested an autonomous quadcopter that used an IMU to control its attitude and a radio to transmit data to a controller, which we also built. The project focused on making the quadcopter as autonomous as possible, so only high level commands such as flight time are sent from the controller to

Texas Instruments TPL1401 Digital Potentiometer (Digipot) offers higher load regulation in voltage-divider applications as a result of an integrated buffered wiper. The TPL1401 makes in-factory calibration and trimming easier with integrated non-volatile memory (NVM) and a simple I2C digital interface to communicate with the device. This device supports I2C standard mode (100kbps), fast mode (400kbps), and fast mode

Introduction Our project is a racing game with human input control that emulates the act of driving a car. We decided on this project, as all three of us greatly enjoy playing games. The goal of the game is to cross the finish line in the shortest amount of time while avoiding obstacle collisions, which
Create a low-cost Paintball Chronograph for less than $40! A ballistic chronograph is a device that records the velocity of a projectile. This particular chronograph I have made has only been tested with a paintball gun and it is relatively simple to make. I have also implemented a function that can record the rate of

In myteenage years, about 40 years ago, I created a dual linear power supply. I got the schematic diagram from a magazine called ‘Elektuur’, nowadays called ‘Elektor’ in The Netherlands. This power supply used one potentiometer for the voltage adjustment and one for the current adjustment. After many years these potentiometers did not function correctly
