Tax return is in

Well late really, last two years after tax department started writing letters.

Serve them right as I got a quite hefty lump sum out of it.

So, after agonising over what to do about GPU based system, I decided I am only dabbling so I opted to simply get an ODROID-XU4 so that I can at least run OpenCL under Python.

Mind you, after toying with Chapel on my quad-core Odriod C1, I will be interested in the Octa-Core Xu4.  I did splurge and get an 32GB eMMC 5.0 with Linux.

I went this way as even now the Jetson TK1 is available (as its now obsolete) in Australia, I am rather more interested now in Chapel.   Not to mention that Chapel appears to be a better approach than Cuda.  That is the appeal, you can take your Chapel code and just change the underlying engine.

So, my cluster will be one ODROID-XU4 and four ODROID-C1.  So, 24 cores all up (not taking the general purpose GPU on the XU4 into account).

If I need more grunt a NVDIA card maybe later, in an 8-core PC, maybe.

However, PhD submission draft this weekend so dabbling is all that I will have time for.

It occurred …

… that after all the fluffing around with TTB on the inherited RaspingBreathBurryDOodlePi, I did rather prefer my mix I built originally on one of my ODROID-W.

Still, now I have got the additional ODROID-C1 it makes more sense for use as the house automation server.

The reason is that there is a UPS module that I can get from HardKernel that will help with survival requirements (given the blackouts we occasionally get in sleepy little Adelaide).

I do rather like the 7″ touch display you can get for the C1 as well.  Although, that isn’t strictly necessary since we will browse into the node-red running on it.


It will do…

… now I can free one of my ODROID-W up from the chore of being the Thing-a-me-Box.

I will even relent and use thing-a-me-box out-of-the-box.


Or not.  Downloaded thethingbox 2.4.0.  Burnt SD card.  Lights flicker but nothing is home on thethingbox.local/ … so the slow painful debug.

First option is I will reburn SD with 2.3.5 before I start attaching terminals etc.

I can’t see the raspberrydoodlepoo on the network even though it is wired up to my wifi extender.

The eth cable I am using is fine with BBB etc.

My PC is wired to the extender so it isn’t the extender.


2.4.0 was a dud!

2.3.5 runs fine.

Installability was a quality attribute applied in old world notions of software quality.  Nowadays who cares right, just make the user fluff about.


Spoke too soon.   2.3.5 loaded up into the gcu page.  Asked me to add email address, passwords, change thingy name.

I hit submit.

It went away and now … does not connect against default name OR new name.


Would you believe you should not believe the boot times proffered for a raspberry pi, especially when it is running TheThingBox.  Somewhat greater than 50 seconds was the problem.  Go a grab a cup of tea closer to the time.

All things come to those who wait.

Two mates came to party with free gifts.

One gave me a large stylish server case so I can build a old dual core server mother board into.  I am sourcing a CUDA board to get best GPU-bang for buck to build a OpenCV/PCL server to give some of my smaller roving bots a vision and mapping service.

To boot, another mate gave me his ODROID C1 so I now have a 4 board ODROiD C1 cluster!

This is for some of the experiments with ERLANG/ELIXIR/RIAK/Phoenix I am dabbling with.  Not to mention RabbitMQ et al.

I have been playing with RabbitMQ and emqtt to sort communication across network with ESP8266 and the 4 ODROID-W skattered around the place.  Currently running emqtt and node-red on an ODROID-W mounted on baseboard but once I have sorted things I will move it to a headerless ODROID-W to sit humming hidden in a small box out of site.

All good fun.
