Good Day Everyone,

I've been playing with my Pine64's for a couple weeks now, and thought I would share some details on observed power usage.

I'm using a multi-port 2.1 Amp per port power supply and running 3 Pine64's on it.

Output Voltage: 5.14v

Boot Max Amps: .66
Idle Amps: .30

I'm using mine as "servers" so they are running multiple shards of Redis on them right now for testing.  I have search shard on a separate processor affinity, keeping 0 for the Ethernet, and 1-3 for Redis shards.

Running Redis-Benchmark against all 3 shards at the same time achieving near 100% CPU utilization on each core as well as putting over 100,000 requests per second on the network.

Full CPU and Network Amps: .81

So this gives me some basic calculations.

5.14 * .30 = 1.542 watts idle usage
5.14 * .81 = 4.163 watts peak usage

Now I do not have anything connected via USB, which would draw additional power to power those devices, so keep in mind that this is board only.  I'm also not running HDMI as I am just using an SSH terminal.

Adding a Microsoft Comfort Curve Keyboard, Microsoft Optical Mouse, and HDMI monitor added about .15 amps to my usage.

Given that my electric cost fully delivered is $0.092 / Kwh, and that there are 24 hours in a day, and 30 days in a month (I know it's not exactly 30, but let's keep the math easy).  

Idle Cost Per Month: $0.102
Peak Cost Per Month: $0.275

While additional devices may cause the Pine64 to draw more ancillary power, overall the power efficiency is really amazing for what all it can accomplish.

As a comparison, let's look at my Dev Redis server.  It's a Intel Xeon E5-2620v2 x 2.  Each core maxes out at about 105,000 requests per second.  Giving it a max capacity taking into account a core for ethernet and io of 105,000 * 23 = 2,415,000 requests per second.

At full draw, with dual network, SSD drives, and such, it's about 130 Watts usage.

That gives me an output of 18,576.92 requests per watt.

In comparison the Pine64 running full out is producing about 84,000 requests per second or 20,177.75 requests per watt!

Now think about that for a moment, the Xeon is running 2.10 Ghz, and the Pine64 is 1.2 Ghz...

As per a lot of the users here I emailed shipping@pine64 regarding my phantom tracking number but I didn't get a response. I received shipping notification on May 27th and was one of the unfortunate people with a LS and CN tracking number. I haven't received any part of my kickstarter/backerkit order and I'm moving in 3 weeks and worried about not only all the parts that have already been shipped out but the rest of my order. I'm hoping this forum will be more conducive to a response and I appreciate all the hard work that has been done, it can't be easy processing millions of orders.

Hi,
I'm currently using longsleep's u-boot and kernel image, which work great.
I'm also trying to build some experimental kernel images, however it doesn't always work.
It's quite a troublesome process to remove the sd card, mount on another machine, recover kernel image, put the sd card back, and boot again.
Is it possible to select alternative kernel image from u-boot without remove the sd card?

Hi pine team! I would just like to check on my shipping status.. Has it even been shipped yet? I'm okay with waiting but would like a rough estimation on when it'll be shipped.

My name: Sayid Hafiz
Backer #: 34,323

Thanks!

If I attach the touchscreen - - - it sounds like I have a wide connector for the video itself, and a narrow ribbon for the touch controls...so...

1) Are these ribbons of sufficient length to work with the acrylic enclosure, or should I abandon that bit?  It's fine if not, as I think I'd have a clunky look just laying the screen on the acrylic enclosure.

1b) Are there / Can I use some kind of short (under 12") EXTENSION CABLES for either/both of these ribbons?

but more importantly...

2) Does the touchscreen have SPEAKERS that work with Android...if so I'm assuming that this is carried by the wide ribbon connector?  If I install the touchscreen Android build, will I have audio through the screen, or do I need to do some other connecting?

2b) Is there something I have to do in SOFTWARE to get audio to work (drivers, etc.)?

Thanks,

are the Jtag debug pin routed to any of the pins?

So my Pine64 2g board of course arrived without the play box I ordered with my pledge. Been able to play around with it just sitting on the desk, everything works good. Since I have no idea IF or WHEN the playbox will arrive, I've been digging around the house for something to use as a sort of case enclosure. Have found a couple of unique plastic boxes that would work, but the ribbon cables for the TP won't be long enough. Can of course just use the hdmi, but if I could find some ribbon cable extensions for the TP I'd be able to hook that up as well.

Anybody know where I could find ribbon cable extensions? just need to extend them 2 or 3 inches....

Sorry posted in other forum then saw this shipping forum which is probably better placed
My package arrived today minus the Z-Wave module - now I think there were some issues with this so not sure if they have shipped the main pledge separately from the z-wave to get stuff out.

Unfortunately they haven't actually said that in the envelope just a little paper slip would have done - now I'm not sure if it was a mistake at shipping or lack of availability.

My backer number is 36141 so I realize I'm at the back of the queue so to speak but just seeking some clarification.

Also the wifi module shipped with a european/us plug is that by design - is their a UK adapter for the PSU? If not I'm sure I can locate a suitable alternative PSU.

Thanks for delivering on what looks to be a great project - just looking forward to getting the z-wave so I can get on with openHab.

Thanks, Paul.

Hi First post here - I'd forgotten a little about the pledge - was pleasantly surprised to see it come through as I had seen they were having shipping/distribution issues.
Haven't felt the need to chase - my assumption was they were to use a cliche a victim of their own success.
