App note from Maxim integrated about alternative method to extend I2C bus. Link here (PDF)

Systems are increasingly requiring greater distances for I2C buses. This article explains how the DS28E17 can be used to extend the distance of I2C devices while decreasing cost.

Hacking and 3D Printing the Future of Violins #MusicMonday

 

via CDM and Adafruit:

Violins: they’re often the first example people site when talking about traditional acoustic instruments. But using new pickup techniques and rapid prototyping, that could be about to change.

violinmakers.org is a community for this new kind of digital age luthier – a place to discuss 3D printing and magnetic pickup possibilities and electric violin fabrication, rather than gut strings and wood carving.

Community member Guy Sheffer spoke recently about why this matters. All that legacy of instrument building has perfected acoustic violins, but electric violins remain crude. As Guy writes: “The challenge is, that while modern instruments have been developing effects and new sounds, acoustic violins have been acoustic for the past 400 years.”

Drones to be Utilized in Antarctic Food Web Research #drone #droneday

From KPBS:

“We study krill so we understand whether its trends and abundance are likely to be influenced by how much fishing effort we do, but also whether that fishing effort will impact the upper trophic levels like penguins and seals,” said Christian Reiss, a senior researcher at the Southwest Fisheries Science Center in La Jolla.

But packing up a research vessel and traveling to the bottom of the world takes time and money. Both are in short supply at a federal agency that is keeping a close eye on shrinking budgets.

That is why the Teledyne G3 Slocum drone is so attractive.

The eight-foot-long submersible can carry sophisticated acoustic devices that are high-tech fish finders. The autonomous machine can identify and measure how many krill there are when it encounters a swarm.

As we soak in the last rays of summer Adafruit would like to send a huge thank you to all the employees that make Adafruit what it is!

Today the team gets a day off in recognition of Labor Day. In the mantra of “Be excellent” Adafruit is always looking for ways to give workers more. We recently added a new paid day off for Election Day, and will keep looking for ways show gratitude and encouragement to the workforce!

Because of the great community and teamwork we are able to do what we do.

Thank you!

Wearable Baby Monitors May Miss Key Vital Signs


via Wareable

Wearable baby monitors are meant to give parents peace of mind. However, that peace of mind relies on trusting the device to actually deliver accurate information.

These wearable baby monitors may be missing key vital signs, according to a new study by Children’s Hospital of Philadelphia published in the Journal of the American Medical Association.

Giant Button Build


This project was sent in by Zach. Find out if you are a winner with a great build and write up! Via Build Cool Stuff:

The conversation went something like:

If you wanted to build an interactive art object what would it be like?

It would grab peoples attention from far away.
It would make people smile.
It would make people feel good about themselves.
It should take people on an emotion journey. In other words, make them feel good and then take that away.

Hmmm… What is something kind of universal that almost everyone likes to do? PUSH BUTTONS!
