Arduino-controlled diesel powered firewood processor

Tuesday, June 22nd, 2010

Over the last few years, my machining mentor Rick has been constructing a diesel powered firewood processor from scratch.The machine is capable of cutting and splitting a cord of wood per hour through precision orchestration of hydraulics and internal combustion. After a few design iterations, all of the mechanical components are bullitproof.

a step by step explanation of a simple yet time-saving process fullfilled by an Arduino and a lot of work.

Shared by Michael and “machining mentor” Rick for the rest of the world

Arduino Intro for kids at FARO

Friday, June 4th, 2010

Wow. It’s seems David Cuartielles is very busy with kids, lately.

During the last two days I have been conducting a workshop for kids on the topic of electronics. The idea of this workshop is to warm up for a course to come later in July when we will be playing around with robots. I have the task of designing 2 or 3 different models of robots together with the documentation needed to run the course.

looking forward to see some robots & kits to play with my son as well!

Behinduino great for breadboard Arduino prototyping

Thursday, May 27th, 2010

Over at MAKE: Japan, Takumi Funada found this nifty project that squeezes an Atmega168 onto the back side of a half breadboard, leaving the entire front available for connections. Looks like it could be handy, as long as you don’t forget that there is a circuit connected back there! I’d like to see one of these made with a transparent breadboard!

DIY Arduino Helicopter with Obstacle Avoidance

Wednesday, May 19th, 2010

Here’s another neat Arduino helicopter project featuring four infrared sensors and one ultrasonic sensor for obstacle avoidance.  We’ve seen an Arduino powered helicopter with four rotors and even one with six rotors too.  This quadcopter, however, features superb stability and obstacle avoidance.  It’s precise distance sensing makes this four rotor drone ideal for indoor flights.

Go live with GameBoy: Max/MSP>arduino>Gameboy

Wednesday, May 19th, 2010

As a vintage interfaces lover myself, I couldn’t ignore a project that makes you going back to my chilhood.

Still I don’t know japanese, but I could guess the setup of this performer by the images ;)

Have a look yourself.

Minor Project – Keyboard input, Matrix Display Output

Monday, May 17th, 2010

[Adam] shared with us a nice keyboard-to-matrix project.

Check out for the (long) code after the break.


Arduino TvOUT Library (with PAL support)

Monday, May 3rd, 2010

Arduino Forum user [mdmetzle] shared a nice tv-out library for Arduino:

I wrote a small video output library called TVout. It is completely interrupt driven to make writing things that need tvout easier. It runs on a resolution of 128×96 with some basic text printing and line and dot drawing for now.

Floppy drives, Arduino board mangled into audio delay effects

Wednesday, April 28th, 2010

[Michael Una] posted nice review on the ongoing Floppy Audio Effects Project on Create Digital Music:

This year, you can add 3.5? floppy drives and disks to your shopping list, courtesy of Daniel McAnulty’s project Floppy Audio Effects. Dan figured out a couple of neat tricks to create delay/reverb effects by writing audio to the disks directly, then reading that information back using a tape head.


Stupid Simple Arduino LF RFID Tag Spoofer

Wednesday, April 14th, 2010

on Instructable an Arduino spoofing of an RFID signal:

RFID tags are all over the place.  They’re used in building access control systems, passports, inventory tracking . . .   This instructable will show how you can use an Arduino and a few simple components (wire coil, transistor, capacitor, resistor) to make a device that can spoof an 125 KHz (low frequency) RFID tag.  This is version 1, so there are many enhancements that can be made, but this version is stupid simple, yet it works.  I did this in a few hours without much previous knowledge of RFID and without any fancy equipment (like a radio tuning hardware or an oscilloscope . . .I guess an oscilloscope is fancy, I need to pick up one of those).

NYC Resistor’s Twitter Teletype

Friday, April 9th, 2010

not the first, but the oldest teletype hack ever (up to now). Check out the video from NYC Resistor.

NYC Resistor was invited to exhibit our old Teletype Model 15 at Eyebeam’s MIXER event last March.  To make life interesting, we used a small Python program to grab tweets from Twitter matching the “eyebeam” keyword.  Watching a 50+ year old device once used to bang out the news of the day turn to printing the trivialities of the moment seems to echo the fate of professional journalists as the world’s attention span dwindles. To make things more interesting, we used a sentiment analysis algorithm to parse incoming tweets for positive or negative sentiment. The results were reflected on an old chart plotter. Positive sentiments moved the mark left. The middle of the paper represented neutral sentiment. Click the image for more photos and a video awaits after the break.
