CNC comes in all shapes and sizes, from huge industrial lathes to homebuilt wire benders. [MJKZZ] has built their own compact rig, using optical drive parts to create a cute but effective laser engraver. (Video embedded below.) The build aims to keep things simple by holding the laser stationary, and moving the bed instead. The laser in question is a 500 mW unit, driven by the Z axis on the Arduin ...

This is a guide to using the motors and sensors from the LEGO NXT set with a Parallax Basic Stamp II or BS2.  However, rather than just providing schematics and sample code for the BS2, I'll be providing some theory on how the sensors work as well.  This way, someone using an arduino or other microcontroller should find this guide at least somewhat helpful. My two main sources of information areTh ...

Hi there I've been here after a long time, and this time I've made a huge project as compared to my earlier ones. This is a full-sized 250 mm X 300 mm work area CNC machine and more interesting things is that it was made in 60$ only. I got some time in my summer vacations and this time I thought to make something apart from my daily work,I can say that it is a fully functional prototype. It is a full versio ...

Working with conductive fabric is fun and it's ideal for wearables, soft circuitry, e-textiles and other projects that take advantage of it's properties. Learning the basics will help you make design and material choices tailored to your application. This Instructable is jam-packed with insights from using it over the years as well as favorite resources for further development. You will learn techniques, su ...

Rotating mechanisms can be a headache when it becomes necessary to deliver power through them. [Igor Brkic] faced just such a challenge when creating his double-pendulum build, and solved it with a little DIY. The project is known as KLAATNO, inspired by the Croatian word for pendulum, klatno. It’s a mechanical installation piece, consisting of a power-assisted pendulum, with a second pendulum fitted a ...

A few years ago I saw an Instructable where Groover had used a pair of DVD-RW drives to make a pocket laser engraver. Inspired by the idea, driven by the recent purchase of a full-sized 50 watt CO2 laser cutter, and roused by the launch of the Microcontroller contest I took the decision to have a crack at making my own mini laser engraver.I have called the project the MicroSlice.What are the features of the ...

Christmas is coming closer, so here is my contribution to put you in the right mood. It is a blog hitcounter, that rings a bell. Literally. It puts a smile on your face, every time someone hits your blog. It consists of an Arduino board, a bell, a servo and a couple of lines of code in c, python and php. Most parts are fairly common and should be easy to get. Step 1: Tools and Materials So what is needed? A ...

https://youtu.be/v0-TlGm9BxM I pull my curtain up and down a couple of times a day. If I watch a movie I pull it down and then, I pull it up to get better lighting. I also pull it down when I go to sleep and I pull it up again when I wake up. I want this process to be automatic, if my curtain rises before I wake up, it will be easier for me to wake up when the clock goes off. Just like those night lights th ...

This project was tough but nothing worth doing is easy and i am ver proud that i was able to accomplish what i did. To know that my skills are further than they once were is a reward on their own.......but how did i get to where i am now? unfortunately i couldn't get it to work in its entirety and this is also my first one so have mercy jk...sorta. Step 1: Supplys First off i had to get supplys... (Arduino ...

Hanging around the machining community online, you’d be more than familiar with clapped out Bridgeport mills, which are practically a meme at this point. But mills come in all shapes and sizes, from the stout old iron from the days of yore, to smaller, compact builds. [Honus] decided to build the latter, and shared the details of the project. The aim of [Honus’s] build is to create a small benchtop mil ...

first of all, i am sorry if i have grammar mistakes, i am asian and i am 13 years old, i study arduino by my self (mostly my self) and this is my first project and also my first instructables. this is the robot that i used to compete with my friends in soccer robot. i did some modifications when i used it but it is broken now, so what i show you here is just a smartphone control robot. i will upload the imp ...

For anyone who’s ever had to make their own tea, steeping it for the right amount of time can be a pain. That’s precisely the problem that the automatic tea brewing robot solves with its painless approach to brewing tea, built by Slovenian electrical engineering student [Kristjan Berce]. You can use the robot by setting a timer on the knob, at which point the robot raises it arm for the tea bag th ...
