HACKEA [LAMPS & CODES]
– May 6th, 2010
[arkadian.eu] inspired us long ago with his hacking ikea post.
We moved it a little bit further, making a whole workshop about it. Here is the report.
And here the codes!

GETTING STARTED WITH ARDUINO! – CHAPTER TWO
– May 6th, 2010
If you happen to follow TronixStuff, [john boxall] is posting very simple yet deep tutorials on Arduino.
Today’s post has several things: taking temperatures, sending data from the arduino back to your PC, opening a library, using LCD screens, and some exercises that will help to consolidate your previous knowledge and help revise it.
check it out!

TO MILLIS() OR NOT TO MILLIS(), THIS IS THE PROBLEM!
– May 5th, 2010
My friend Vittorio made a nice article about multitasking in arduino (without delay(), using the millis() function).
It’s in italian, but the last code is a pre-made skecth in witch you can place evertything you need (to be timed).
really useful!

PianoDuino é um experimento simples que integra Arduino, Processing e uma biblioteca para manipular sons, a SoundCipher. A idéia serviu para experimentar o Multiplexador / Demultiplexador 4051.
[Bruno Soares] created PianoDuino, a very good way to understand how to deal with a multiplexer, Processing anda cool library dealing with sound,SoundCipher.

MILLION DOLLAR BABY – NOTES OVER A NEW BUSINESS MODEL
– May 3rd, 2010
[dcuartielles] re-posted a nice pecha kucha style resumé of the open hardware experience from [Philip Torrone] and [Limor] at Foo Camp (MIT) at the Ignite hour. Thanks David for the link.
At O’Reilly’s foo camp east 2010 at Microsoft’s NERD center (MIT campus) we presented “Million dollar baby – Businesses designing and selling open source hardware, making millions” at the Ignite hour. 20 slides, 15 seconds per slide – we tried to capture the excitement and great work from just a few of the dozens of open source hardware companies & resellers. Above, slides, photos & video (m4v). Special thanks to all the companies who helped with some data points and to the OSHW workshop group. There are additional videos/posts/tweet from other attendees, this is our quick video we were able to put together on the train ride back from MA to NYC.

RAILWAY-RELATED GERMAN SUPREMACY HACKED [JOKE!]
– May 3rd, 2010
If you happen to be a railway geek, you may know this Intellibox:
Between the control computer and the railway is Uhlenbrock’s Intellibox(German site). Its RS232 interface supports Märklin’s P50 protocol, plus extensions called P50X. The extensions include an event system for acquiring information about changes in the railway state. The most important use for this is reading track sensors, but it can also be used to keep the program in sync with other control devices.
It is ment to be made out of modules (for sensors, turnaout control and so on), but as a [spanish twit] adviced me, down at [databeaver's domain] they found a way mimic the begaviour of these modules, wirelessly. (nice conbination between *BELOVED* Arduino mini and Xbee)
I’m starting to make and use some custom hardware components based on theArduino microcontroller boards. The first one is a wireless s88 transmitter/receiver pair using an XBee radio module. This allows me to get rid of long sensor wires and it has potential to be cheaper than Märklin’s (horribly overpriced) s88 modules.The firmware source code for both the transmitter and receiver can be found from SVN. Schematic for the transmitter is below; the receiver can be connected directly to the S88 bus (see the source file for pinout).

ARDUINO TVOUT LIBRARY (WITH PAL SUPPORT)
– 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.

ADAFRUIT ON SPEED AT IGNITE!
– May 3rd, 2010
In this video, Limor and Phil (Adafruit Industries) make a super-speeded-up introdution to the concept of Open Source Hardware and the business it generates. They had only 20 slides at a pace of 15sec/slide to make a point and I think they managed pretty well. The presentation was made during this weekend’s Foo Camp at MIT at the Ignite hour. Here what Limor posted onAdafruit’s blog:
