PINE A64, First $15 64-Bit Single Board Super Computer

@MattSpeller said:

33% faster clock speed (which is kinda meaningless) - I'd like to see it benchmarked. Especially for power consumption.

33% faster on a more powerful CPU. So likely a lot faster.

ehhhhhh we'll see

Here is some info. The A53 is the direct replacement for the old A7 architecture.

Their not actively selling yet.. crowd-funded...

Screw it, funded em for the 64+.

I'll wait to see one benchmarked

@MattSpeller What's your concern? Have you ever, outside of the infamous Pentium 4, seen processors move backwards in power? You really think that ancient 32bit procs might be faster than current 64bit ones?

Curse you for stealing my ready example of why waiting and not being an early adopter is prudent

I worked it in though so I think we're all good.

A53 is not an early adopter, A53 is a venerable three year old processor at this point. It's been the ARM standard for a long time. Even when Raspberry Pi was new the A7 was a surprisingly old, slow processor.

http://www.arm.com/products/processors/cortex-a/cortex-a53-processor.php

Here is ARM's own quote: The Cortex-A53 delivers significantly higher performance than the highly successful Cortex-A7, and is capable of deployment as a standalone applications processor or paired with either the Cortex-A72 or Cortex-A57 processor in a big.LITTLE configuration for optimum performance, scalability and energy efficiency.

From the video http://www.openhab.org/ looks interesting.

I don't know what I'd use OpenHAB for anything quite honestly.

I don't have a smart thermostat, or Smart Lights or what ever.

So I guess, can someone explain where I might find OpenHAB useful, I highly doubt that I'd program an app to work with a smart thermostat if I had one etc.

One project I want to do is turn on the lights in my place when I get home from work and my phone joins the wifi.

Another is to automate my door lock with a system that would not require any permanent modification to my apartment door / deadlock.

I've also thought about making a really nice wall mounted lamp with LED strings embedded into a large slab of wood, possibly driftwood with a nice soft glass plate over them to diffuse the light

Yet another is to build my indoor hydroponic garden - this will happen in 2016 for sure. I'm going to use SMT LED lamps and mount them to a common ground / heatsink in the form of a huge aluminium box tube that I can put a fan in the middle of and create a heat pipe that will not only provide light and cooling for LED but also heat and breeze for plants

Still another is to get an OBDII BT module for my car and build a heads up display with an OLED screen so it shines up from the dash onto the windshield and display temp / pressures / coolant / gas / mileage / etc

Something else that's bugged me a bunch is to build a 3D dot matrix cage for my apartment with IR LED beacons so I can fly a mini quad copter around with a built in AI and use it to water plants / auto recharge it's self

For a commercial product I've long thought that something that monitored mains power usage from stove / major appliances and alerts you when they've been on for a while and can receive pokes to update power usage / status would be awesome because forgetting if you've turned off the oven is annoying as fk and useful to seniors and their children.

Another commercial product I've wanted to do is a real air guitar with sensors in a special pick and on your finger tips but I think this is years away from reality with sensor sizes. I think it could be built into a special Tshirt with sensors but dont care enough to chase it. My cousin did an air drum kit project and it's dope, sensors on tips of sticks and you drum away in mid air over a sensor pad.

Another commercial product I want to do is auto-tint windshield that will track eye position and dimm oncomming headlights. This is a dope idea and I think I can do it but with automated cars coming whats the point.

Something that's bugged me for a while is it's hard to get cameras to all turn on and record at the same time and it'd be cool if you could control them all simultaneously. Most high end ones have an IR input sensor for a remote and I'd like to suss out all their codes and build a big blaster to hit record all a the same time for easier / lower staffing on large many angle camera shoots. This will let smaller production teams do cooler shots.
