I hope DHD remembers us little people when he's sipping champagne, in his private jet, whilst travelling between his penthouse in Hong Kong and the country chalet in Monte Carlo.

I've modified the code to piggyback the room temperature on the transmission that controls the valve, almost for free, and so now I get live monitoring of the whole house.

This will have a switch to disable it on individual nodes, for anyone who does not like the idea of broadcasting this data, eg for security reasons, and I may well change the details, but I'm pleased with this so far.

If it's still fun, you're still on the right track.

Ever considered a Kickstarter campaign?  In Canada this often gets projects extra press coverage, which doesn't hurt the funding, if you know what I mean.  The media love Kickstarter because you basically write the article for the journalist's column of the day.

Probably not appropriate at the moment though we have considered it repeatedly.

Basically the team needs to be available flat out for media access for an extended period, I believe, and we don't have that sort of time now!  I haven't yet given up the day job (it's happening but not this month).

I'm pleased to be able to say that we've got some funding to work on the cheap/easy sensor/actuator part of our technology:

So, lots more sensor fun coming up over the next year!

Small thing this weekend, but kinda working up to the big project starting next month...

Tweaked the code for relatively fast and low-energy start-up, with energy harvesting applications in mind eventually (a little like this JeeLabs stuff http://jeelabs.org/2015/03/18/micro-power-snitch-last-part/ but I failed to get my current-clamp-driven stuff working yet).

So I have a single unit powered from my rather quiet urban turbine.  When it spins up at all it sends JSON plain-text stats on the ISM band at 868.35MHz, initially just an ID to minimise energy requirements, then, if it stays running, some other data periodically (supply voltage and temperature at the moment).

Here's a sample of the log entries.

Code: [Select]
[ "2015-03-22T16:10:53Z", "", {"@":"b39a"} ]
[ "2015-03-22T16:10:55Z", "", {"@":"b39a","B|mV":3247,"T|C16":376} ]
[ "2015-03-22T16:11:13Z", "", {"@":"b39a"} ]
[ "2015-03-22T16:11:23Z", "", {"@":"b39a"} ]
[ "2015-03-22T16:11:25Z", "", {"@":"b39a"} ]
[ "2015-03-22T16:16:29Z", "", {"@":"b39a"} ]
[ "2015-03-22T16:16:33Z", "", {"@":"b39a","B|mV":3247,"T|C16":375} ]
[ "2015-03-22T16:16:41Z", "", {"@":"b39a"} ]
[ "2015-03-22T16:16:43Z", "", {"@":"b39a"} ]
[ "2015-03-22T17:03:39Z", "", {"@":"b39a"} ]

Not a peep out of it for over 4 hours, since of course doing anything with a wind turbine other than trying to take it down causes the wind to drop.

I find myself wayyyy down the other end of the gadget scale, yet still doing roughly the same thing.
Analog temp sensors and plain old voltage divider sending data to an antique Sutron data logger (collected from an Environment Canada clearance auction). 
The logger is 1980's equipment (although the boards inside have 1995 printed on them it's obvious in other ways that they were leveraging older designs at the time).





I'm still waiting for the on-board memory (378 kB!!) to fill up and start overwriting.  So far the log goes back to January when I plugged it in.  I can download the data via a 9-pin serial cable to a DOS-based terminal interface program.  Don't know what I'm going to do if I have to abandon my XP laptop!

SparWeb;
IF for some reason you "have to" give up the XP and must stick with Windows based computers, have a look at DosBox , I have found it very easy to get Dos based (FoxPro stuff) to work on even W7 64-bit . Takes a little attention the first time around for mapped drives but once done it just works!

I've used it so much to keep DOS based (actually MainFrame stuff) working I'm just about to make a donation :).
I hate throwing away something that still works too  :o.

Hope that helps!

LOL  Antique computers:  I actually downloaded DosBox a little while ago but didn't install, once I found a different work-around for a different problem.  One of these days I'm going to do it and play Frogger and Pong again.

You're right - DB would do the trick for the Sutron data downloads if the XP laptop ever quit on me.  I actually have two XP laptops.  One has an iffy hard drive but still boots up so I will not throw it away yet.  Back up!

Bruce - I just remembered - the last time this came up, you made the pitch for Linux.  Have you lost the Ubuntu love?

Not even close to losing the love for 'nix!!
Have a read fun read over in the pub about the hijack-ed thread!
I know work for StL's FD which is city guberment controlled  :P . So making stuff play nice nice with M$Soft is a daily occurrence.
MY house is something totally different,, I'm nowhere near the level of Damon, tho  8)

Hi,

I thinks rumours of my skillz have been greatly exaggerated, though yes, all my servers are Linux one way or another bar one ageing Sun CoolThreads.  But my laptop is a Mac; uncool I know!

On the topic of the thread though, excitingly enough we're in DesignSpark (RS Components):

http://www.rs-online.com/designspark/electronics/eng/blog/opentrv-saving-energy-via-the-internet-of-things

I've been a customer of theirs for 30 years, so rather exciting to get a post up with them!

The fact that the box is 3D printed gives it the WAY COOL geek factor  8).

In fact even that all-in-one visual prototype is 3D printed (with 'wrong' plastics) because the proper injection moulds are ~60k!

Forecast winds peaking at about 50mph here (well LHR/EGLL airport) overnight with gusts to 60mph and running though tomorrow, just as I notice that my little turbine is falling apart.  May have to take it down in advance or attempt to fix it up or tie it up.

Any suggestions?

About the same weather here. 

Did it survive?  Are you looking for a replacement WT now, Damon?

I took it down.

I established that MotorWind is still alive, selling spares and new turbines.

In the mean time we need to do some work on the wall the WT was secured to.

The Iot Launchpad project is officially alive; see the "IoT Launchpad" links near the top here:

http://www.earth.org.uk/open-source-programmable-thermostatic-radiator-valve.html

In particular we're started thinking about our sensors:

http://www.earth.org.uk/note-on-IoT-sensor-set.html

and our backhaul (I even blagged a satellite transceiver, and space on the top of a London building!):

Hi,

I finally got a landing page for the research stuff together:

http://www.earth.org.uk/IoT-Launchpad-research.html

I have to close the comms backhaul one soon (D17) since I'm already over time on that, so if you're desperate to contribute so do very soon please!

http://www.earth.org.uk/note-on-IoT-comms-backhaul.html

Also, I'm starting to get the security one off the ground and all input welcome:

http://www.earth.org.uk/note-on-IoT-security.html

Damon

PS. Other excitement is that we've won an exhibit stand at interop.co.uk and are partners in London in the Climathon that runs worldwide 18th/19th.

For any Europeans here that may be interested...

We're putting together a crowdfunding campaign in Sept/Oct for the first CE stamped version of OpenTRV (full of AVR goodness).

If any of you would be interested then PM me your email and I can add you to our mailing list.

If Bruce doesn't think it too horribly salesy I can put up a link to the (still in progress!) site for people to sign up directly.

NOT to mention the amount of knowledge you have imparted here !!
This is more than acceptable
