An oscilloscope is a measuring instrument used to visualize and analyze electronic signals. It is commonly used in various fields, including electronics, telecommunications, engineering, and physics. Overall, oscilloscopes are essential tools for...
One of the goals on this project was to make as little modification to the original load box as possible. The mechanical construction of the unit helped with this. The top cover of the box is just a flat sheet of aluminum. This made a convenient place...
About the Project Introducing HammerHead, a simple line follower robot powered by the ATmega328 microcontroller and TCRT5000 IR sensors. This Robot is equipped with N20 motors, an L293D motor driver, and some features that make line-following an...
Story Hi, all If you're not familiar with WLED, the WLED Project is a web server that controls LEDs and SPI-based chipsets. It can control two types of LED strips: digital addressable and analog non-addressable. WLED also provides open protocols to communicate...
The monitor shows the daily routines of one month, but stores the entire year. When the routine is accomplished, just press the corresponding day button. This changes the LED light on the button from white to green. I picked the colors green and white,...
Making the Fox Head I'd never made a puppet head before but I'm pretty crafty and during my cosplay days I'd discovered the material Worbla, which is a thermoplastic that can be easily shaped when heated and has adhesive on one side that is also heat...
At the request of several of my subscribers, I decided to explain to you how you can make such an instrument yourself. The device is extremely simple to make and represents the most common oscillator whose frequency of oscillation depends...
Introduction The idea was inspired by a YouTube video by Michael MJD, who experimented with running Linux on a Wii. This sparked curiosity about the Wii's potential beyond gaming. Research led to the discovery of the Pi Music Box project for Raspberry...
After completing the Loud-ESP project, I wanted to get more focus on what Loud-ESP was created for - home media server application. I did an ESP Audio Dock series of boards, including the Duo board that is essentially a strip-down version of the Loud-ESP....
After completing the Loud-ESP project, I decided to focus my work on a more powerful and more purpose focused Louder-ESP board that is built around TAS5805M I2S DAC. It is capable of driving 2-channel 25W speakers, so clearly it has much tougher requirements...
