LIVE CHAT IS HERE - http://adafru.it/discord
https://plus.google.com/+adafruit

1) Add +Adafruit Industries to your circles
2) Post a message/comment HERE and say you want to show off a project and we will add you the “Show and Tell” circle.

Then just look for the hangout announcement on the very same page later for your invite. There’s an 8 to 10 (at the same time) people limit per hangout, so if it’s full try later or just pop by next week same time. Some weeks are packed!

At 7:30pm ET you will see a link to the hangout. Just keep your mics muted until we call on you and have your project ready.

For those who just want to watch, you’ll be able to watch it live on Google+ ‘s broadcast feature on Adafruit’s page AND it will be recorded and uploaded to YouTube automatically.

Want to join the #showandtell Here’s how:

DIY BGA (Ball Grid Array) Rework Machine
https://blog.adafruit.com/2018/06/20/diy-bgaball-grid-array-rework-machine/

A really neat rig by Adafruit forum user Julian Lorah, he describes the BGA Rework Station he has built. If anyone that has done soldering and unsoldering (rework) knows, ball grid array (BGA) parts are very hard to work with. Julian has repurposed an older project for a platform along with a thermocouple and a hot air device to develop just the right methods to safely and effectively remove a very large BGA device that was not working on a circuit board.

IoT Hydroponics with #AdafruitIO
https://blog.adafruit.com/2018/06/20/iot-hydroponics-with-adafruitio/

ufire needed a way of monitoring EC, pH and the temperature of their hydroponics setup over the internet. They found a solution in using a combination of a ESP32-based development board and a few different types of probes to monitor the plants. This setup was connected to Adafruit IO as separate feed. Combining these feeds into a shiny dashboard would be the next step for ufire.

Can IBM’s ‘SUMMIT’ Supercomputer Predict the Future?
https://blog.adafruit.com/2018/06/20/can-ibms-summit-supercomputer-predict-the-future/

Scientists have high hopes for the world’s fastest computer, which is now up and running at Oak Ridge National Laboratory in Tennessee after its June 8 launch.

This stat puts things in perspective:

A $200-million, water-cooled monster that covers an area the size of two tennis courts, the computer, dubbed “Summit,” has been clocked at handling 200 quadrillion calculations a second (or 200 petaflops). That’s more than twice as fast as the previous record-holder, China’s 93-petaflop Sunway TaihuLight, and so fast that it would take every person on Earth doing one calculation a second for 305 days to do what Summit can do in a single second.

the NBC News article continues,

Roughly 10 percent of people who take an opioid painkiller slip into addiction, says Dan Jacobson, a computational biologist at the laboratory. “That screams genetics to us — otherwise everybody would get addicted,” he says. He and his team plan to use Summit to compare the genetic profiles of 600,000 individuals — in this case U.S. military veterans — against clinical records showing whether they were prescribed opioids and if they became addicted.

From caitlinsdad on Instructables:

Everyone will want one. As an homage to the fairy godmother of wearables Lynne Bruning, I created this Neopixel Rainbow Tutu of Righteousness. Groovy.

How to Auto-reset Beagle Bone Black Ethernet
https://blog.adafruit.com/2018/06/19/how-to-auto-reset-beagle-bone-black-ethernet/

Sometimes the Ethernet port on a Beagle Bone Black does not work on power up. There is a design issue in the BBB that causes the Ethernet PHY chip to sometimes power up in an undefined state where it can not make a valid link. Currently, the only fix is either a physical reset button press or a power cycle. But what if you don’t want to do that or you don’t have access to the BBB in question? Well, lucky for you josh.com wrote up a great guide on a reliable software method to detect what state the board is in on power-up.

They write:

Install this package on your BBB and it will always have a working Ethernet port when it powers up – although it might take a couple of minutes and a few automatic power cycles.

The fix relies on an undocumented bit in a status register – if this bit is 1, the Ethernet connection is not working, 0 when it is OK. Sneaky but… it works!

The Immigration Effect #IHM2018 #ImmigrantHeritageMonth #CelebrateImmigrants
https://blog.adafruit.com/2018/06/20/the-immigration-effect-ihm2018-immigrantheritagemonth-celebrateimmigrants/

In celebration of the many benefits immigration has brought to this country here is an interesting article from Pro Publicaabout the potential boon immigration could have for the US economy. There is also an interactive graph you can play with showing the predicted effect of different immigration rates.

In an analysis for ProPublica, Adam Ozimek and Mark Zandi at Moody’s Analytics, an independent economics firm, estimated that for every 1 percent increase in U.S. population made of immigrants, GDP rises 1.15 percent. So a simple way to get to Trump’s 4 percent GDP bump? Take in about 8 million net immigrants per year. To show you what that really looks like, we’ve charted the effect below. You can see for yourself what might happen to the economy if we increased immigration to the highest rates in history or dropped it to zero – and everything in between.

“Immigration is a great economic policy opportunity and it’s important to document the impact of that,” said Douglas Holtz-Eakin, an economist who served on the President’s Council of Economic Advisers in both Bush administrations. He agreed with the basic conclusions of Moody’s analysis, and said that 1.15 percent was a reasonable estimate of the effect of immigration on GDP.
