Tips On Picking The Right Case

June 6, 2008 by 12 Comments


Finding the right enclosure to house your latest project can be tricky, so Sparkfun wrote up some handy tips on the how to pick the right one.

The most important tip is to have your components measured before acquiring a case; even being a few milimeters too small can put you back at square one. To do this right, it’s useful to look at the dimensional drawings of prospective cases to get a sense for the size. These typically include recommended shapes for PCBs too.

You may find a case that meets your dimensional needs but doesn’t have the appropriate mounting bosses. To get the placement right, screw some plastic standoffs to the PCB, then use super glue to attach them firmly to the case.

Tips on button choices, hole drilling, and other typical issues with case modification can also be found in this guide. If this is something that’s been stumping you, give it a look.

How-To: Binary Clock Using A Freeduino SB 2.1

June 6, 2008 by 10 Comments


Solarbotics recently released its own version of the Arduino microcontroller development board. They based their board on the Freeduino design. We thought this would be a good opportunity to review the new board as well as present a How-To about building a simple binary clock. Along the way we’ll cover some basics on attaching LEDs and switches to a microcontroller.

CRT Blinkenlights

[Julien] sent in his group’s twist on the now classic blinkenlights project. Oddly, the writeup is entirely in jpg form, so I can’t know if he’s finished it yet. One of them promised to send it in during our New uses for old CRT monitors HackIt, so it’s nice to hear something about it. While the classic blinkenlights uses building windows as pixels, this version divides CRT displays into four squares.

Bionic Senses

Various cybernetic limb and organ replacements were recently featured in IEEE’s flash demo called The Bionic Body Shop, but we were most interested by the bionic eye and the cochlear implant (we already discussed the featured powered exoskeleton). These are notable for the fact that they are not merely high-tech prosthetic replacements strapped to or worn on the body, but implants that are housed within the body and work with flesh-and-blood sense organs on a much closer level than any preceding technology.

Playing The Building With David Byrne

June 3, 2008 by 3 Comments


Do you remember the solenoid concert that used a sequencer to control several solenoids striking different surfaces? Musician David Byrne has taken the concept and executed it on a much larger scale with his “Playing the Building” installation in an old municipal ferry terminal in New York. Devices that bang the girders, rattle the rafters, and blow through the pipes of the building are attached to the only object inside, a weathered pipeorgan. Every key is wired to different device in the building, each producing a unique sound. Attendees are invited to fiddle with keys of the organ to produce sounds from the building’s various materials, thus playing the building like an instrument. Here’s a video from the installation.
