1KHZ TO 20MHZ LOW POWER OSCILLATOR

1KHZ TO 20MHZ LOW POWER OSCILLATOR

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 …

EOG-Controlled Video Game

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 …

TEXAS INSTRUMENTS TPL1401 DIGITAL POTENTIOMETER (DIGIPOT)

TEXAS INSTRUMENTS TPL1401 DIGITAL POTENTIOMETER (DIGIPOT)

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 …

Paintball-Ballistic-Chronograph

Paintball/Ballistic Chronograph

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 …

Digital-Controlled-Linear-Power-Supply

Digital Controlled Linear Power Supply

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 …
