The Chartered Institute for IT (formerly the British Computing Institute) produced this short film about Lady Ada Lovelace as part of their Information Pioneers series. Each of the pioneers has his or her own film, and they are all worth checking out.
There’s also a poll, where you can vote for your favorite pioneer.
NOW IN STOCK – Analog panel meter [50uA] – Analog panel meters are not a blingy as LEDs but they add a touch of elegance and are easier to read quickly. This one is fairly large and is easy to open up the front with two screws and replace the gauge. There’s a ‘zero adjust’ as well. The back has four 3mm (4-40) screws, 6.5cm apart, so its easy to attach to a box or enclosure
Size: 3.125″ (8 cm) square, 1.25″ thick (the panel is 0.5″, the coil sticks out another 0.75″)
Measures: This panel is 0-50uA which means it can be used with any kind of power supply!
To use with a digital output microcontroller (such as an Arduino or AVR), connect the black wire to ground, a resistor in series with the red wire and the other side of the resistor to a PWM output. Then sweep the output from 0 to 100% PWM to swing the meter. The resistor should be = (Power supply Voltage) * 20,000. So for a 5V supply, 100Kohm. For a 3.3V supply, 66Kohm.
IN STOCK – MONOCHRON KS0108 Graphic LCD. A big, bold, beautiful, black LCD with white back-lit pixels. This LCD is the graphical upgrade to those popular 16×2 LCDs, but allows full graphical control. This LCD is used in the MONOCHRON kit, we had to custom order these to get the black color so they are more expensive than the more common blue & white ones.
Black background with 128 x 64 ‘monochrome’ white pixels
Low power white LED back-light
The LCD is driven by on-board 5V parallel interface chipset KS0108 and KS0107. They are extremely common and well documented
The palm-sized notebook is designed to be a hackable hardware platform for Linux developers, akin to what the Arduino board is for electronics projects. Key to making that vision a reality is keeping every part of the product open: the circuit board designs are licensed for reuse, every chip included uses open-source drivers — and the system, of course, runs embedded Linux.
Copyleft hardware means more than just purchasing the device from the manufacturer and customizing the software, however. The board schematics are available under the Creative Commons Attribution-Share Alike license, which ensures that anyone can legally manufacture a variation of the device, provided that they also publish their schematics under a copyleft license — just as the GPL requires of software derivatives.
This project is very cool. We hope the folks who wrote the article would consider the *hundreds* Open source hardware projects… (their statement is not correct)
“Copyleft hardware is not nearly as widespread as copyleft software; the Qi Hardware cites just four other projects that follow the same approach: the Elphel digital camera, Pandora game console, the Milkymist One visual-effects video synthesizer, and the Arduino microcontroller. The Arduino’s success in particular is an example of what the team behind the Ben hopes to see develop around its NanoNote project.”
This video illustrates real-time MRI of vocal performance. It includes examples from a soprano and an emcee/beatboxer. This video was featured at the Sounds and Visions Session, of the International Society for Magnetic Resonance in Medicine (ISMRM) Scientific Sessions, May 2006, Seattle.
This is a handy Arduino shield: we’ve had a lot of people looking for a dedicated and well-designed data logging shield. We worked hard to engineer an inexpensive but well-rounded design. Not only is it easy to assemble and customize, it also comes with great documentation and libraries.
