Maker Faire Report - Teaching Kids Java SE Embedded for Internet of Things (IoT)

I had a great time at this year's Maker Faire 2014 in San Mateo, Calif. where Jake Kuramoto and the AppsLab crew including Noel Portugal, Anthony Lai, Raymond, and Tony set up a super demo at the DiY table. It was a simple way to learn how Java SE Embedded technology could be used to code the Internet of Things (IoT) devices on the table.

The best part of our set-up was seeing the kids sit down and do some coding without all the complexity of a Computer Science course. It was very encouraging to see how interested the kids were when walking them through the programming steps, then seeing their eyes light up when telling them, "You just coded a Java enabled Internet of Things device!" as the Raspberry Pi-connected devices turned on or started to move from their Java Embedded program.

The AppsLab at Maker Faire

It will be interesting to see how this next generation of kids grow up with all these Internet of Things devices around them and watch how they will program them. Hopefully, they will be using Java SE Embedded technology to do so. From the looks of it at this year's Maker Faire, we might have a bunch of motivated young Java SE Embedded coders coming up the ranks soon. Well, they have to get through middle school first, but they're on their way! ;-)

Maker Faire 2014 - Java Technology and IoT come together

Make sure to come out to the Maker Faire 2014 this year at the San Mateo Event Center on May 17 & 18. It will be a weekend full of fun and high tech toys. Plus, come see our Java SE Embedded technology demos on the Raspberry Pi!

Jake, Noel Portugal, and the Oracle AppsLab did a great job on the DiY table, and Vinicius will show cool stuff on the IoT Panel wall. Plus, come meet other Java Embedded technology makers who will be staffing our Oracle Java Embedded Technology area.

Here's a quote:

It'll be a good time for the whole family! So, come out and enjoy the (cooler) weather and a nice day playing with technology, crafts and talk with the people who make them.

How to Build Your Own $3.2bln Nest Startup Using Java SE Embedded Tech (Part 6)

After showing how to connect the LCD Touchscreen from adafruit in Part 5 for this Java SE Embedded thermostat project, I figured out a simpler solution for the relays needed to turn on and off the furnace, fan, and A/C of a home heating and cooling system (just like the Nest thermostat).

So, it's time to show how to do a time-honored tradition in high tech start-up prototyping: Refactoring.

I found this cool Single Relay Board from Parallax. It can control up to 120VAC at 10 amps, but we only need to control 24VAC 1 amp relays for the home furnace, fan, and A/C. And most importantly, this Single Relay Board can take a 3.3 VDC signal from a microcontroller or Raspberry Pi running the Java SE Embedded platform (like we are doing in the project). No need for SPI or i2c, just a straight GPIO high value (3.3VDC) from the Raspberry Pi header pins from a Java SE Embedded app will control the relays. Cool!

So, I've got a bit of refactoring to do of my previous blog posts to swap in 3 of these Single Relay Boards (go ahead and order 3 if you are playing along at home). But, it's all good. Refactoring is part of the process of high tech start-up prototyping, right? :-)
