Using NXT Components With a Micro Controller

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 ...

DIY CNC for 60$ (Large Work Area)

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 ...

DOUBLE PENDULUM USES CUSTOM SLIP RINGS

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 ...

The MicroSlice V1 | a Tiny Arduino Laser Cutter

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 ...

Arduino XMAS Hitcounter

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 ...

Motorized Pulldown Curtain (Phone & Radio Controlled)

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 ...

A DIY BENCH-SIZED MILLING MACHINE

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 ...

NO NEED TO WATCH YOUR TEA, THIS ROBOT DOES IT FOR YOU

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 ...

STEAMPUNK RADIO LOOKS THE BUSINESS

Radios are, by and large, not powered by steam. One could make the argument that much of our municipal electricity supply does come via steam turbines, but that might be drawing a long bow. Regardless, steampunk remains a popular and attractive aesthetic, and it’s the one that [Christine] selected for her radio build. The build cribs from [Christine’s] earlier work on a VFD alarm clock, using similar tubes ...
