How to Build Your Own $3.2bln Nest Startup Using Java SE Embedded Tech (Part 5)

We now have power to your Raspberry Pi. Next, we need to hook up the cool LCD Touchscreen from adafruit.com so that your Java SE Embedded thermostat app will have a UI. Lady Ada has some rockin' cool gear for your Raspberry Pi at her Web site!

See the cool video demo of the TFT touchscreen below:

To hook up her LCD Touchscreen to your RPi so that your Java SE Embedded app can use it, just follow these two sets of instructions from adafruit.com.

First do the assembly: TFT touchscreen assembly

Next do the software installation: TFT touchscreen software

That's it for this part. You can also check out the other steps at the adafruit.com Web site for screen calibration and other optional set-up steps. But, with the above minimal steps you now have a working touchscreen.

Next up, we will connect the PiFace for the relays needed to turn on and off your furnace and A/C via a Java SE Embedded app. That's when the stuff gets real... Or, sparks fly... One, or the other. :-)

The Path to a $16 Billion Acquisition? Build a Java ME App

As everyone saw in the press already, Facebook bought WhatsApp (maker of the startup mobile messaging app and service) for a hefty $16 billion. There was a lot of armchair analysis done just after the announcement, on how WhatsApp could be worth $16 billion. Here's a blog post (not mine) from the TextIt Blog, written by makers of the TextIt tool for SMS apps, that concludes the answer is Java ME technology (J2ME), and that Facebook bought WhatsApp for $16 billion because the WhatsApp Java ME port is available for feature phones, which if you look worldwide, still outnumber smartphones by a lot (a fact many developers and entrepreneurs overlook to their detriment).

See:

Java ME tech is the Answer

Here's a quote:

 So it finally happened, Facebook snatched 
 up WhatsApp for the not so bargain price of 
 $16B to the simultaneous head explosion of 
 every entrepreneur in Silicon Valley. A 
 common cry echoed around the world "But, 
 but, how is WhatsApp any different than 
 iMessage / Facebook Messenger / Hangouts?"

 To that, I have one answer: J2ME
So, even though it might not happen the same way for your mobile startup, you might want to consider the analysis by the TextIt blog post, that if you want to think big for mobile, you should consider a Java ME port of your mobile app to make sure you cover the whole market, not just the smaller smartphone (iOS and Android) market. Apparently, Mark Zuckerberg and Facebook did... :-)
