Brooklyn Microgrid #SolarPower
https://blog.adafruit.com/2016/04/25/brooklyn-microgrid-solarpower/

With your powers combined…Brooklyn Microgrid is a brilliant plan. From Scientific American:

But that could soon change. Cameron and many of her neighbors have signed onto a project called Brooklyn Microgrid, which is installing infrastructure to enable a small network of Park Slope buildings—and another cluster in neighboring Gowanus—to sever themselves from the larger grid. The microgrid would independently distribute locally sourced electricity without mediation from the utility.

BeagleBone Black GPIO Benchmark
https://blog.adafruit.com/2016/04/25/beaglebone-black-gpio-benchmark/

Thanks to Joonas for sharing – check out the full post on his blog, code and life.

Look what the mailman brought: It’s a shiny (or maybe matte?) BeagleBone Black, freshly arrived (actually it’s been over a month, but time sure flies…) from Newark element14! I’ve been doing Raspberry Pi related hacking for a while, but especially when the Pi was still fresh and new, I did from time to time consider if the grass would be greener on other side of the fence. Or blacker, in this case, as I mean BeagleBone Black.

Precious Plastic is a set of machines that allows anyone to set up a small-scale plastic recycling workshop: https://goo.gl/Qj1ex9

According to Scientists from the University of Georgia, there is an estimated 8 million tons of plastic waste dumped into the ocean each year; the team used data on the amount of waste generated and how well it is disposed of in 192 coastal countries to come up with their estimates.

What's surprising is that only 10% of what we throw away actually gets recycled, but with the Precious Plastic machines, users are able to recycle almost any plastic trash to create new things, including 3D printer filament, which could result in micro businesses popping up all over the world, each doing their little bit to help make the maker movement more sustainable.

One day, Richard Hulskes came up with the crazy idea of 3D printing a life-size humanoid robot to act as a “physical avatar” for hospitalized children unable to explore the outside world.

This is what happened…

We just published a new blog post about ESP9266. This article is about building projects that will last for years on a single battery.
Enjoy!

The Most Sustainable Restaurant In The World Might Be This School Cafeteria #makereducation
https://blog.adafruit.com/2016/04/26/the-most-sustainable-restaurant-in-the-world-might-be-this-school-cafeteria-makereducation/

Nice piece from FastCoExist on a sustainable school cafeteria in Los Angeles.

The greenest restaurant in the world—at least according to one ranking—is a school cafeteria. The Muse School kitchen, in a private school just outside Los Angeles, currently holds the highest ranking with the Green Restaurant Association.
The school grows its own food, composts, and the entire kitchen runs on solar power. But the biggest difference from typical school lunches is probably the fact that they decided to stop serving animal products.

As Seen on Show and Tell: Audible notifications by a Grandfather’s clock
https://blog.adafruit.com/2016/04/25/as-seen-on-show-and-tell-audible-notifications-by-a-grandfathers-clock/

Last week on Show and Tell, Ekel Laszlo shared his wonderful raspberry pi powered sound notification build. He’s also posted it up on hackaday.io!

I fell in love with the sound of a grandfather’s clock. But it was too expensive for me. And that clock has no alarm and snooze option. And it knows nothing about my emails or text messages.

Can Drones Help Accelerate Landmine Cleanup? #drone #droneday
https://blog.adafruit.com/2016/04/18/can-drones-help-accelerate-landmine-cleanup-drone-droneday/


From the University of Bristol via Popular Science:

The research, led by Dr John Day of the Interface Analysis Centre in Bristol’s School of Physics, is funded by Find A Better Way, the charity founded by England and Manchester United legend Sir Bobby Charlton. Find A Better Way is currently funding nine different university programmes in the UK and Croatia researching faster, cheaper, and safer methods of landmine detection.

If you are having trouble sourcing APA102 pixels, there appears to be an alternative that works and can be clocked faster.
 
Received my 1st test batch of the new SK9822 Pixel. It is as previously stated a direct drop in replacement for the APA102 pixel, with some minor differences. I can confirm its maximum stable data rate is 30Mhz. I ran 31Mhz and it worked fine, but 32Mhz make it go completely crazy (The APA102 could not go above 20Mhz). In standby mode the pixels also consume WAAAY more power than the APA102. I had a test strip of 72 pixels on 1 uninterpreted strip. Both ends had the same 5V 40A power supply attached. When no LEDs were ON, the strip drew 0.3A. However running a test animation drew the same amount as the APA102 would at its identical intensity levels. I have an English datasheet here http://www.elec-tron.org/wp-content/uploads/2016/04/SK9822-LED.pdf with thanks to +Jürgen Skrotzky The driving system is exactly the same as APA102! (Tests were done using an RPI and using my own SPI driver )
