[11:53] <SpeedEvil> Ah - cruel ebay.
[11:53] <SpeedEvil> http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=290625404173&category=3243&_trksid=p5197.c0.m619
[11:53] <SpeedEvil> I'd hoped I could justify this as a reasonable purchase, for home-heating.
[11:53] <SpeedEvil> But I'm at risk of being one of those 'just 10 more' people when my limit was 150 quid ago.
[11:54] <Laurenceb> pvc-Ti
[11:54] <Laurenceb> what the hell
[11:54] <SpeedEvil> hmm
[11:54] <SpeedEvil> Good question.
[11:54] <daveake> Upu, what was the solar panel for?
[11:54] <Laurenceb> COP 4.8 at 40C water temperature
[11:54] <Laurenceb> holy shit thats good
[11:55] <UpuWork> daveake I have no idea, I think they'd made Hydrogen from solar power earlier i the series or something
[11:55] <UpuWork> it wasn't connected
[11:55] <SpeedEvil> Laurenceb: That will be at higher output temps though.
[11:55] <daveake> ah
[11:55] <UpuWork> they had the generator there too
[11:55] <SpeedEvil> Laurenceb: I'm considering cheating.
[11:55] <SpeedEvil> Laurenceb: Get another meter installed 'as I'm going to be renting out half my house'.
[11:55] <SpeedEvil> Put it on E7
[11:55] <Laurenceb> yeah
[11:55] <SpeedEvil> Run the heatpump on that, into a large thermal store.
[11:55] <UpuWork> I think they were insinuating they'd made Hydrogen or they were using it for a fuel cell or something
[11:55] <Laurenceb> or power it off solar panels XD
[11:56] <SpeedEvil> Laurenceb: Alas - I have no solar panels, and the free solar has gone away.
[11:56] <Laurenceb> its probably not good enough for that work
[11:56] <Laurenceb> need COP of 10 or so for that to work
[11:56] <SpeedEvil> You mean not large enough?
[11:56] <SpeedEvil> for solar panels, you mean?
[11:56] <Laurenceb> yes
[11:56] <SpeedEvil> For solar panels, you'd - sanely - need another bit of kit in addition.
[11:56] <Laurenceb> otherwise its best to use vacuum tubes and water central heating
[11:57] <SpeedEvil> A VFD for the motor.
[11:57] <SpeedEvil> As otherwise, the meter runs backwards when a leeetle cloud is overhead
[11:57] <SpeedEvil> I should ring round the free panel vendors, and confirm it's come to an end, and I can't get them.
[11:58] <SpeedEvil> On an amusing side-note.
[11:58] <SpeedEvil> I worked out the other day that using the most efficient light source (near-IR laser diodes) you can just about make it pay to light the solar panels using E7 electricity.
[11:59] <Laurenceb> lol
[11:59] <SpeedEvil> (if you get the 45p/kWh FIT)
[11:59] <SpeedEvil> Of course, the lights would cost _way_ more.
[12:00] <fsphil> would take a long time to fill a balloon with a solar panel and water
[12:00] <SpeedEvil> Electrolysis is slow.
[12:01] <daveake> But in fsphil's case he'd still have enough hydrogen by the time his notam arrives :p
[12:01] <fsphil> for two at least
[12:01] <daveake> :D
[12:02] <fsphil> good idea though, solar panel and storage at the launch site
[12:02] <daveake> I guess we'll all be using hydrogen sometime, when helium runs out
[12:02] <fsphil> between launches it replenishes itself
[12:02] <daveake> :)
[12:03] <SpeedEvil> daveake: And then back to helium, when hydrogen runs out.
[12:04] <Laurenceb> Rossi will turn it all into copper
[12:06] <costyn> UpuWork: so is James May the nice bloke he seems on tv?
[12:09] <Laurenceb> hes a sexist meysogynist, havent you heard the feminazis?
[12:09] <Laurenceb> and i cant spell
[12:09] <SpeedEvil> Isn't he a Maysogynist?

[12:11] <costyn> maysogynist lol
[12:12] <SpeedEvil> Laurenceb: quite a bit, generally.
[12:12] <Laurenceb> guess thats why ground source helps
[12:12] <Laurenceb> or sewer source XD
[12:13] <Laurenceb> my favourite idea
[12:13] <Laurenceb> dig a tunnel down the the nearest sewer and put a heat exchanger round it

[12:14] <Laurenceb> cant you plot it and imgur it :P
[12:14] <SpeedEvil> It's a 3D graph
[12:14] <SpeedEvil> doesn't really work well
[12:15] <SpeedEvil> The -15 to 20 axis is temp, 10-100 is load, 0-3500 is heat pumped
[12:15] <SpeedEvil> 'using 1:2:5' shows the COP versus those factors.
[12:16] <SpeedEvil> In short.
[12:16] <SpeedEvil> This is a really good (and expensive) inverter from toshiba.
[12:17] <Laurenceb> i see
[12:17] <SpeedEvil> Looking at the 100% load side - it varies from a COP of 6, to a little over 4 at -15C
[12:17] <SpeedEvil> The heat pumped goes _way_ down.
[12:18] <Laurenceb> pumped to what temperature?
[12:18] <SpeedEvil> Bad things happen at anything over about 50% load from 0-5C external or so, as the outside ices up lots.
[12:18] <SpeedEvil> I'm guessing 25C air temp
[12:19] <Laurenceb> i see
[12:20] <SpeedEvil> Deeply annoyingly, I can't seem to find sane datasheets for the cheaper heatpumps.
[12:20] <SpeedEvil> Meh.

[12:21] <Laurenceb> pond source heat pump?
[12:22] <Laurenceb> might freeze it completely solid in very cold weather
[12:22] <SpeedEvil> Air source is lots cheaper than ground source.

[12:22] <Laurenceb> that could get messy
[12:23] <Laurenceb> how about a mixed source system
[12:23] <SpeedEvil> Gets complex fast.
[12:23] <Laurenceb> pumps from a water system
[12:23] <Laurenceb> then water system can come from solar vaccum panels
[12:23] <SpeedEvil> It can end up as cheaper just to put in a larger ground loop.
[12:23] <Laurenceb> maybe some ground source, and some car radiators

[13:42] <Zuph> Hey, it's a start. These guys aren't building pacemakers, they're making LEDs blink.
[13:42] <fsphil> Would that run Linux? I'd love to see linux on a single dip ic
[13:43] <zyp> no.
[13:43] <Zuph> No way
[13:43] <Zuph> Still a couple orders of magnitude of power away from that.
[13:43] <zyp> linux requires an mmu
[13:43] <Zuph> Now, a useful RTOS? Yes.
[13:43] <fsphil> bit to go then
[13:43] <Zuph> zyp: Nope. See uClinux

[13:43] <zyp> but that doesn't count :p
[13:43] <fsphil> though I'm slowly moving towards smd parts myself, so I might be able to make my own linux-running device soon
[13:44] <SpeedEvil> I expect linux in qfn36 in about 5 years.
[13:44] <Zuph> Heh, good luck :-p
[13:44] <Zuph> Easiest to solder linux capable micro is still ike TQFP144 or something.
[13:44] <SpeedEvil> Say 4M ROM/RAM
[13:44] <SpeedEvil> yeah
[13:44] <SpeedEvil> err - not really
[13:44] <zyp> I prefer soldering smd over soldering pth
[13:45] <SpeedEvil> 386 - PGA can be soldered easily.
[13:45] <Zuph> I mean modern micro.
[13:45] <SpeedEvil> :)
[13:46] <SpeedEvil> And it's pretty close to that, yeah.
[13:49] <Zuph> As an aside, TI has some cortex M3's in very reasonable SOIC packages.
[13:50] <Zuph> The LPC part in dip is LPC1114FN28
[13:50] <Zuph> 32k Flash, 4k RAM.
[13:50] <Zuph> Dissapointingly, no ADC like most of the rest of the family. Otherwise, just fewer peripherals.

[13:53] <Laurenceb> arduino that doesnt suck
[13:54] <Laurenceb> got my F4discovery flashing its leds :P
[13:54] <Laurenceb> it has 10 different colour ones.. looks like a christmas tree
[13:55] <Laurenceb> they seem to be targetting arduino users
[13:55] <Zuph> hehe
[13:56] <Zuph> ST, Or olimex?
[13:56] <Laurenceb> F4discovery
[13:56] <SpeedEvil> I guess there aren't any DRAM solutions that will drop below about 35 IOs.
[13:56] <Laurenceb> i have like 20 eval boards on my desk now XD
[13:56] <Zuph> Meh, I'm not sure about that, Laurenceb
[13:56] <Zuph> A lot of the arduino crowed picked 'em up, but I don't think they'll be able to make much use of it.
[13:57] <Laurenceb> F4?
[13:57] <Zuph> Yeah
[13:57] <Zuph> Even the tools from ST aren't the easiest to use.
[13:57] <Laurenceb> i doubt it - theres ~0 stock
[13:57] <Zuph> They gave a ton away for free.
[13:57] <Laurenceb> no that was before F4
[13:57] <Zuph> Probably 1/4 of the people in my hackerspace have free F4 discoveries.
[13:58] <Laurenceb> in the UK?
[13:58] <Zuph> US.
[13:58] <BrainDamage> Laurenceb: 20 F4, or 20 different eval boards?
[13:58] <Laurenceb> ah
[13:58] <Laurenceb> eval boards
[13:58] <BrainDamage> that doesn't asnwer me :p
[13:58] <Laurenceb> different
[13:58] <Laurenceb> i only have 3 F4 boards :(
[13:59] <Zuph> SpeedEvil: Yeah, 35 is about as low as you can go :-\

[14:00] <SpeedEvil> Zuph: Using SDRAM auto-increment to read out a camera
[14:01] <Zuph> ah, neat
[14:01] <SpeedEvil> So you setup the address, then toggle clock 4096 times, deselect the camera for a moment, toggle in a new address, and repeat.
[14:02] <Zuph> Very neat!
[14:03] <SpeedEvil> It was based around a teeny smt32, a RAM, a camera, a SD card, and not much else.
[14:03] <SpeedEvil> Never got built though.
[14:03] <Zuph> heh
[14:03] <Zuph> Some of the New F4s have camera interfaces built in.
[14:04] <SpeedEvil> Idea was a camera 'throwie'
[14:04] <SpeedEvil> With a teeny solar panel, and RF out.
[14:04] <Zuph> Oh, I like that idea.

[18:21] <DanielRichman> jcoxon: we've got a web page with the last logs on the todolist, but that is also a good idea

[18:21] <DanielRichman> i suggest you add the suggestion to this, jcoxon : https://github.com/ukhas/habitat/issues/151
[18:21] <TimZaman> anyone knows why that messed up my altitude?
[18:21] <DanielRichman> you don't want the ` after $ALT

[19:33] <TimZaman> did anyone else use it?
[19:33] <fsphil-laptop> I'll be doing another one as soon as possible
[19:34] <fsphil-laptop> there's a few people looking at it, they may use it in the future
[19:36] <fsphil-laptop> oooooh
[19:36] <fsphil-laptop> just figured out why it didn't plot your payload on habhound, it's because your receiver station has the same name as the payload
[19:36] <fsphil-laptop> I'm not checking the type of object

[19:39] <TimZaman> i dont know what habhound is
[19:39] <TimZaman> talking about animals
[19:39] <fsphil-laptop> it's spacenear.us, but for laptops
[19:39] <TimZaman> today i learned a new english animal
[19:39] <TimZaman> the Heron
[19:39] <TimZaman> i have a laptop?
[19:41] <fsphil-laptop> linux only at the moment, https://github.com/fsphil/habhound

[20:09] <fsphil-laptop> looking forward to that

[20:13] <TimZaman> fsphil what exactly is habhound more specifically
[20:14] <jcoxon> its a mobile version of spacenear.us
[20:14] <fsphil-laptop> it's a little program that displays a map, and plots the payload and chase cars using data from habitat
[20:14] <jcoxon> with the database locally that only syncs with interenet
[20:14] <jcoxon> so if you are moving and lose connection its not a disaster
[20:14] <fsphil-laptop> yea, it can also work of a local database that's synced with the main online one
[20:14] <fsphil-laptop> though that's untested
[20:15] <fsphil-laptop> actually there's something I can do for sunday's flight
[20:15] <nosebleedKT_> gnite all!

[20:16] <fsphil-laptop> I'd like it to do predictions and things, but it may never get to that point. More just me playing about atm
[20:16] <fsphil-laptop> though it works well
[20:17] <fsphil-laptop> I noticed yesterday that openstreetmaps have a download for their entire worldwide map - 18gb :)
[20:17] <fsphil-laptop> so in theory the map could be served locally without any net connection

[20:21] <daveake> Worldwide eh? Handy for those floaters ....
[20:22] <SpeedEvil> It's somewhat nontrivial to render it.
[20:22] <SpeedEvil> It's ~200G or so of XML, uncompressed.
[20:22] <fsphil-laptop> yea, it's not just png images
[20:22] <daveake> Sounds like a challenge
[20:23] <fsphil-laptop> ooch - didn't know it was that big uncompressed
[20:23] <TimZaman> looks sweet fsphil
[20:23] <fsphil-laptop> I see some interesting images coming in TimZaman
[20:26] <TimZaman> fsphil not my bad
[20:26] <TimZaman> fldigi showed them fine
[20:26] <fsphil-laptop> it looks like two different images being mixed
[20:26] <fsphil-laptop> probably just a second image with the same id

[20:36] <Laurenceb_> Zuph: itd help if there was a manual
[20:36] <Laurenceb_> how the hell do i setup openocd ?
[20:37] <BrainDamage> openocd with what hardware?
[20:38] <Laurenceb_> make -C build && sudo ./build/st-util [/dev/sgX]
[20:38] <Laurenceb_> wut
[20:38] <Laurenceb_> https://github.com/texane/stlink
[20:38] <Laurenceb_> there is no ./build
[20:39] <Laurenceb_> oh wait there a tutorial
[20:39] <Laurenceb_> phew
[20:39] <BrainDamage> openocd doesn't support stlink
[20:39] <BrainDamage> you have to use that, yeah
[20:40] <Zuph> Laurenceb_: Yeah, you use stlinkk *in place of* openocd
[20:40] <Laurenceb_> oh i see
[20:41] <Laurenceb_> sudo . / s t u t i l f u bar
[20:41] <Laurenceb_> but that isnt there either
[20:41] <BrainDamage> did you make?
[20:41] <Laurenceb_> oh in gdbserver
[20:41] <BrainDamage> what?
[20:42] <Laurenceb_> nvm
[20:42] <Zuph> Do a "make" in the root, to make the libraries, then do a "make" in the gdbserver directory to make the st-util executable.
[20:42] <Zuph> Add the udev rules to your rules.d directory, restart udev, then plug it all in.
[20:43] <Zuph> Then execute ./st-util <dev>, where <dev> is the stmf4 in your /dev/ directory.
[20:44] <Zuph> then you can connect GDB to localhost, and execute commands/program/whatever
[20:44] <Zuph> You do need to make sure your linker scripts link everything to the right location. st-link won't correct the elf based on ram/flash.
