Make your own Vj controller [Arduino meets Resolume]

Monday, May 17th, 2010

Nice upcoming workshop in Rome at the end of the month:

I’m really glad to announce a new Arduino workshop, VJ-related, in Rome, at the end of the month. [...]

Now, it’s preatty straightforward sending data to PD, Processing or MAX/Msp with Arduino. Over the years, I always asked myself in which way Arduino, my favourite beloved italian board, could have helped the (other) big majority of visualist who use mass vj software, like Resolume 3 or Modul8.

So the idea of this workshop came in my mind. Arduino meets Resolume is the prototyping of a simple yet modular little vj console, inside a VHS case. A normal Arduino workshop with some hacking, some programming, a lot of amusement. A perfect intro to many vjs who want to make a turntable out of a hackek HD, or just learn how to solder/desolder/heal some electronic equipment.

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.

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.

Tutorial: Reading a 12-Button Keypad

Thursday, April 8th, 2010

Nice nifty tutorial (difficulty level = 1) on hooking up a 12 button keypad on your Arduino.

Most keypads like this are wired so it makes it straightforward to figure out what button is being pressed. With 3 columns and 4 rows of buttons, you only need 7 wires. Typically all the buttons in a column are connected together with the same wire, and all the buttons in a row are connected together with the same wire. To determine which button is pressed, you apply a voltage to the wire attached to a column and then check the wires attached to each row to see if current is flowing through any of them. If so, then the switch for a particular button is closed (button pressed). Then you proceed to the next column and try each row again, etc. Not rocket science — just scanning a bunch of switches to see which one is closed. In fact, there is a keypad library in the Arduino Playground that makes it easy to do this.

[Michael] from nootropicdesign.com is using a 10 wires non-standard keyboard. Check-out his code.

DIY Toner Transfer Circuit Etching

Tuesday, March 16th, 2010

Well. As most of you I begin my day hanging around in different forums. One of them (one of the firsts) is the Arduino Forum, with his new layout.

In these day a thread took my attention: P18F4550 made his first Arduino Shield. When questioned to make a step by step guide of the all process he posted wonderful pics of the all thing.

TwypeWriter (Twitter Monitoring Typewriter)

Monday, February 22nd, 2010

Nice Oomlout wat to have a twitter-related typewriter. Arduino (+ethernet shield) searches for a keyword and then physically prints the results for everyone in the office.
Code ready.

Good work!
