I love Drupal! It 's a very powerful CMS, has the support of a huge community, there are thousands of free modules. Features such as CCK, Taxonomy and Views make it an incredible development platform. You can build real web applications without writing a line of code. But unfortunately many people are frightened by the first approach. One of the first issues that it faces a novice Drupal user is the lack of a WYSIWYG HTML editor (what you see is what you get) on the client side in the core installation of the CMS. I had to struggle hard to figure out which combination, of the dozens of editors and modules available, it was the right one. I was hoping that with the release of Drupal 7 an editor was finally built in but was not the case, so I decided to publish this guide (or tutorial if you prefer) to configure Drupal 7 to use the WYSIWYG editor CKEditor, buttons for entering images within articles and photo viewing with a Lightbox script. This is what I think right now the best configuration for Drupal 7, but of course there are dozens of other possibilities.

Working on my MIDI ribbon controller I needed to implement a menu to easily configure several parameters, but    I found information on how to handle a menu, how to manage an LCD display, but very poor info on how to combine the two things. However, thanks to Alexander Brevig Menubackend library I managed to create the menu I wanted.

Arduino The Documentary.

There are many professional MIDI controller out there: keyboards, drum pads,    mixer, pedals, etc.  One type of controller that interests me most is the ribbon controller because I wanna try to emulate with the  software  plugins what can be done with instruments such as the Ondes Martenot. I think that this type of controller  fits very well to control virtual instruments such as strings and horns, as it is characterized by a position and pressure sensitive   ribbon, so you can control in a very intuitive way the notes pitch and velocity  .   I  decided to do a MIDI ribbon controller using Arduino.

Recently I needed to configure the Arduino midilibrary on my Mac running OS X Snow Leopard 10.6.5. Despite the excellent documentation found on Arduino.cc I struggled a bit to find the exact procedure to install an external library in the IDE. So I thought I'd publish this post to help those who will be similar troubles.

Some time ago, me and Laura needed to develop a software that enabled a user to indicate the completion of a repetitive action pushing a button every 5-10 minutes. The operator generally worked a couple of meters from his computer and each time he had to get close and press F2. Unfortunately there was no chance for placing a wireless keyboard closer to the operator because he is not sitting, so we thought to use a big wireless button to hang by the wall.

You have to watch the Peter Funch photo galleries! The pictures are made by shooting the same place from the same position for several days, then some details are taken by each of the pictures and are combined in a unique photo. A fascinating perspective on the human being and time.

The Polaroid SX-70 cameras are great but now are 30 years old and so it is obvious that start to deteriorate. With this post I can not explain how to repair any failure of the sx-70, but I will discuss one common defect, which I personally found on my two cameras. I put a new pack of film, close the door, the motor starts to spin making noise, no picture is ejected, and the motor does not stop until I extract the cartridge or until the battery runs out. The problem can also occur suddenly after shooting few pictures. However, looking around the internet I found some valuable information from a Flickr user, Redlomo, in a discussion that explained the steps needed to fix the sx-70. Following this advice I managed to fix both my sx-70 and, to make life easier for those who want to try on their own, I tried to film the second repair in order to make available this tutorial.

Among the photographers who use Polaroid films the most famous is Maurizio Galimberti. His portraits are amazing and you can admire them on his website.

Just to be clear: to shoot like Galimberti you need study, smartness, creativity and sensitivity, and a real artist should still try their own way. So there's no surprise to see Maurizio Galimberti showing his technique. Galimberti actually works with many techniques, but probably the best known is that of the Polaroid

 In another post I wrote about the Gakken SX-150, now I explain how I created a "giant" controller (50cm) for this mini synthesizer, but in order to make this change I had to first understand a little more about the original control system.
The strip on the Gakken SX-150 is simply a resistor of about 75 Kilohom. Looking at the schematics I found on the Matrixsynth blog I could think for an alternative to the control system of Gakken.
I used a sensor called Spectrasymbol Softpot parallel to the standard sensor.
This sensor is available in various lengths, I bought the 50cm long (the maximum available).
