It would be great if you could create your own filament. On the face of it, it seems easy to do, but as [Thomas Sanladerer] found out when he was a student, there are a lot of details that can bedevil your design. His extruder sort of works, but he wouldn’t suggest duplicating his effort. In fact, […]

I got a relatively inexpensive 6040 CNC machine, and have been spending most weekends making the thing work, and then cutting stuff, learning the toolchain, and making subsequent improvements. Probably 90% of my machine time has been on making improvements. It’s not that the machine was bad — I got the version with ballscrews and a decently

This project is based on mostly items which are easy to find. The idea is to take two unused computer disk units and combine them to create an automated drawing machine which resembles a CNC machine. The pieces used out of the drives include the motors and railings from both of the drives and the

Rev 2.5 – tidied up the 3D printed parts and updated the plug connector to a common PCB unit. Rev 2 – ultrasonic “button” replaces manual push-button. Pushing a button is so old fashion, particularly when I’m already using an Ultrasonic sensor. Why not use an ultrasonic sensor to activate the can level detector! Rev

You can’t fake that feeling when a $4 microcontroller dev board can stand in as cutting-edge 1980s technology. Such is the case with the working transputer that [Amen] has built using a Raspberry Pi Pico. For a thorough overview of the transputer you should check out [Jenny List’s] longer article on the topic but boiled down we’re talking

The design was inspired by a product that is also presented on Instructable called “Arduino Basics with Night Light” (https://www.instructables.com/Arduino-Basics-With-…). Originally, the device is only allowed to change the LED lights by pushing down a button; after adding the codes and circuits (added: a speaker to notify the user for using recommended relatively peaceful color-blue/a

JCB Machine is very popular because it is heavy-duty construction equipment in the civil industry. JCB is also known as the backhoe loader. It can be used to load or unload the trucks very quickly. It is used for the construction of roads, loading and unloading of trucks, and many more things. Every construction company
There was a time when people like us might own a tube tester and even if you didn’t, you probably knew which drug store had a tube testing machine you could use for free. We aren’t sure that’s a testament to capitalistic ingenuity or an inditement of tube reliability — maybe both. As [Usagi] has

In Banksy’s book, Wall and Piece, there is a very interesting quote; “Imagine a city where graffiti wasn’t illegal, a city where everybody could draw whatever they liked…”. This sounds like it would be a very exciting city to live in, except for those of us who do not have an artistic bone in their body.

Air Quality Prediction is a project that balances Arduino development and Machine Learning. I have always found the world of machine learning captivating but was never able to run models on real-time data. Arduinos provide the solution with a vast array of sensors supported on their microcontrollers. As a result, I knew that I wanted
