In this section, you will find tutorial and projects that our staff has created from scratch. Starter projects are for beginners looking to do simple projects that take less than 60 minutes. If you are looking for a challenge, we also have intermediate projects that will generally take more than 60 minutes.
Since the very first invention of the logic gate in the 20th century, the constant development of such electronics has taken place and it is now one of the simplest yet fundamentally important electronic components in many different applications. The Binary Calculator will be able to take multiple bits as input and compute the summation and subtraction using various logic gates
This guide will walk you through the assembly and set up of the CNC 50mW Laser Engraver. All parts used in this guide are included in the kit and some replacements parts can be purchased individually. All software used in this guide is freely available online.
This project is a sound meter shown by LEDs. It makes use of an electret microphone, op amp, and LM3914 LED Driver IC. How it is used is the louder the environment around the sensor is, the more LEDs are turned on by the LM3914. It’s a fairly simple and interesting project that’s ideal for newcomers to electronics.
The concept of a railgun consists of propelling a conducting object along 2 conducting rails due to a magnetic force and an electric force. The direction of the propelling force is due to electromagnetic fields called the Lorentz force.
The small AC to DC Voltage Converter project uses four diodes to make one bridge rectifier to transfer AC power to DC power. Also, we use capacitors to remove ripples in the circuit. After we transfer from AC power to DC power, we need to use one 5v voltage regulator to give 5v DC output from 12 v DC output.
This is a piano board with eight push button switches that allows you to play one octave (Do Re Mi Fa So La Si Do) and with this one octave you can try to play some songs you like. For this project there are some important knowledge you need to know before you start.
This project demonstrates the basics of digital logic, the characteristics of a NE555 timer, and demonstrates how binary numbers are counted. The components used are: a NE555 timer, a 12-bit ripple counter, two 2-input NOR gates, a 4-input AND gate, a 2-input AND gate, and a 2-input OR gate. The logic gates, NOR, AND, and OR come in TTL and CMOS equivalents which can be found at Lee’s Electronic. This project is a simple egg timer with two settings: hard or soft boiled and comes with a reset...
