Hi all, 4am here and I guess I was supposed to sleep last night. Totally skipped my mind.
Just finished my build on Edison & mmeowlink & subg_rfspy... leaning heavily on the work of @oskarpearson and @ps2.
Managed to get it into a reasonable case with the battery included inside
with 31 hours of runtime and 2.5 hours to charge
Using two of these batteries in series for 7.4v:
and by stealing all the charging electronics from another 2-cell Li-Ion battery

Hi guys, I’m having a really tough time with the wifi connectivity. Running Raspbian Jesse with the very common Edimax wifi dongle, 8192cu driver. I was having this problem and after 4 nights, I totally rebuilt the SD card, installed OS from scratch, configued wpa_supplicant.conf and got connected. I was on! I ran raspi-config, rebooted, and now “no wireless interfaces found” again. lsusb shows the usb sees it, lsmod shows the driver is loaded. I bought a powered USB hub today, tried that, rebooted several times, and it just won’t use the wifi card. I tried reinstalling the drivers- something like "apt-get install firmware-realtek” but it was already up to date. I’m running "sudo ifup wlan0” over and over, like suggested, and nothing. Any suggestions would be welcomed!

@ps2 @JaysonEwer it's actually a 754, which is why my build is not pure OpenAPS - I am using a Medtronic remote control and adjusting my glucose using only micro-bolus commands and suspend commands. Hence I call it "BOBS Pancreas", with BOBS = Based On Bolus/Suspend. I rely heavily on OpenAPS toolkit for it, but my entire loop is essentially a 1000 or so line python program.
@bewest, purple with sparkles, which brighten it up enough to make it almost pink. :P
@ps2 @JaysonEwer more images of inside:
So in short, everything I have done should work for pure OpenAPS, but would be simpler, because you could leave out the Medtronic remote and its battery. It would be very close to what @oskarpearson has previously shown us.

@JonnyRox Hi and welcome! I'm in the UK (Glasgow) and I'm a little bit further on than you, but not looping yet. I've got a Pi + carelink set up and communicating with a Medtronic 722 pump (I'm a T1 so this is for myself). @oskarpearson is in London and I'm sure there will be a few more of us in the UK too. I can hopefully help you out with getting started as I've just went through the initial steps in the past 2 weeks myself.
Andrew Warrington
@andrew-warrington
Mar 16 2016 11:08
@oskarpearson went with 7.4v so that power would be provided over the USB port to the TI dongle. I guess there are other ways to manage to get power to the TI dongle but this was what I chose at the time without thinking too much about it. I did at one point try a smaller config at 3.7v with an Adafruit Powerboost up to 5v but the powerboost itself needed some space so it wasn't a huge savings in terms of cubic cm -- and then I realised that config left me with no power on USB as well, so I abandoned it.
yes I got 3 hours of sleep. ;)
@johnmales The TI dongle is in by USB yes. I basically bought a standard micro USB cable which was easily bendable, and cut it, then soldered a standard port on the other end. Now, for this to work properly as a USB "OTG" cable (making the Edison act as the host rather than as a device), I needed to short pins 4 and 5 of the USB micro receptable on the breakout board. I did this on tiny pads on the underside of the board... will eventually put up an explanation + picture of it in the repository.

@colinlennon thanks! She's currently using a newer Medtronic pump but has a 722. I figured for my first iteration I'll go down the tried-and-tested route with a 722/Pi/Dexcom G4. She doesn't currently have a CGM and may get one on the NHS in September but I'd prefer to sway her towards buying one outright that we can use for this. Once I've got something up and running (and understand fully how it all works) I'll then look at miniaturising etc.
I've got quite a lot of 3D printing experience, Solidworks and a couple of Ultimakers here at work which I'm planning to use to the max. I'll make all my 3D files available for anyone to use. I can see a lot of circuit boards and batteries in plastic boxes from RS and Farnell and it'll be nice to help turn that around a bit!
Colin Lennon
@colinlennon
Mar 16 2016 12:01
@JonnyRox Yip, a 722 is ideal. I didn't have a CGM, so I bought a Dexcom G4, but rather than buying the full pack (at the full price!), I bought the transmitter but not the receiver. I've built an xdrip, which picks up the signal from the transmitter and sends it to an app on my Android phone via Bluetooth. That app syncs up with a website, and my OpenAPS rig will download recent readings from this website (instead of me plugging in a G4 receiver via USB).
You might want to have a look at https://gitter.im/nightscout/dexdrip for more details about xdrip
Be aware that it does mean my OpenAPS rig is reliant on an internet connection though. The cost saving is significant. You can't buy the transmitter alone from Advanced Therapeuritcs, but you can from www.diashop.de and they ship to the UK.

@colinlennon was that the €399 option you went for? I thought CGMs were way more expensive than that. I think we're going to need a receiver as well, because her workplace has no mobile internet coverage and no wifi. Has anyone used the Medtronic CGM? This is most likely to be the one she'll get on the NHS if she gets one.
@oskarpearson thanks buddy :smile:
Colin Lennon
@colinlennon
Mar 16 2016 15:11
@JonnyRox yeah, that's it. The G4 sensors last longer than the Medtronic ones. Some people manage to get 3 weeks from a single sonsor. I can get 2 weeks easily, haven't tried any longer than that yet.
Mikael Rinnetmäki
@mrinnetmaki
Mar 16 2016 15:12
I’ve used both, and find the Dexcom ones much more reliable.
Colin Lennon
@colinlennon
Mar 16 2016 15:12
There is a way to create an 'offline' closed loop without the receiver, but I don't think it's widely used yet, or clearly documented.
So it's probably best to use the Dexcom receiver in your situation, at least initially.
You can also replace the batteries in the transmitter rather than buying a replacement. I've not tried this yet but I will whenever this transmitter dies! Here's some info on that - https://www.ifixit.com/Guide/Dexcom+G4+batteries+Replacement/55536
Oskar Pearson
@oskarpearson
Mar 16 2016 16:15
@JonnyRox We're on the Medtronic CGM - and are likely to be on it for another 6 months or so as we've signed a year-long contract for them for discount sensors.
People have very mixed results with them. For my wife they are reasonably accurate, and with her wearing them on her arm even more so. They don't last very long (though on her arm they are better)
They also suffer from poor range talking to the pump - we get "lost sensor" messages fairly often
There are also some (reasonably minor) issues getting data from the pump occasionally. Once or twice a month data will just stop flowing. It's a well known bug in the interface library but we've not yet managed to fix it.
The vast majority on closed loop is actually using the Dexcom sensors - and I expect we will probably go that way too at the end of the contract.
They might work for you, they might not.... there are reports of two siblings, one of whom can't use Medtronic as they are completely inaccurate.. but the sensors work perfectly for their brother/sister
Unfortunately it's quite an expense to test it out and see
Oskar Pearson

Jon Hughes
@JonnyRox
Mar 16 2016 17:36
Sounds a lot like Dexcom is what I'll go for then. Next question is what Pi to use, I guess. Doesn't the latest one have wireless and Bluetooth already onboard? I guess I should ask if there's a FAQ answering these questions because you folk probably get asked the same questions by all the noobs!
Colin Lennon
@colinlennon
Mar 16 2016 17:39
I'm starting with the latest one (3B). It has Wifi and bluetooth on board, yes. I also have a Pi Zero which I might try and use in a more portable rig. The big question re. the 3B is power consumption - hopefully I'll be able to test that out in the next few days and can let you know what I find.
Oskar Pearson
@oskarpearson
Mar 16 2016 18:34
@JonnyRox it's a complicated process, but you might want to consider the Edison. It's much smaller than the pi
If you want you can post me a ti stick or we could meet up and I can write the firmware etc. For "legal reasons" you'd still need to do all the hard work of getting a loop running, etc. So to some degree it depends how much hardware type work you've done before
I'm experimenting with a pi zero loop too at the moment. It's a bit inconvenient in that it doesn't have wifi, but it can't be beat price wise
in all cases I'd suggest going with a ti stick instead of a carelink of at all possibrl🔞
Gaaah bloody phone keyboard! 📲
The range on the ti stick is much better than the carelink

@everyone From time to time the idea of a tool to assist with setting basals has been discussed. We've been using autosens for about a week and it really goes a long way in improving our child's BG variability, but I'm still thinking it would be great if we could have NS or OpenAPS recommend the programmed basal rates. I'm completely willing to invest both time and money into such a project, but want to do so only if it is a tool others would actually want to use. Thoughts?
Jon Hughes
@JonnyRox
Mar 16 2016 19:46
@oskarpearson I was thinking to start with a Pi to get me going, then once I was more confident I would move on to the Edison as a 'revision 2'. But you could probably talk me round that!
Toby Canning
@TC2013
Mar 16 2016 19:47
@JonnyRox I think you are better served to start with the Pi unless you have considerable electrical wiring and soldering skills
You'll find the Pi will be great for home use no matter what
We use the Edison for our mobile unit and it is awesome for that

Mar 16 2016 19:48
@colinlennon I don't know my Raspberry Pis all that well (because I've only used Arduinos up until now), but chatting to some of the guys at work who use them a lot they seem to reckon you can down-clock them quite a lot and ramp the LEDs right down which ought to significantly lower the power consumption.
Toby Canning
@TC2013
Mar 16 2016 19:50
I've tried some experiments with downclocking and you likely don't want to go under 700mhz, which did save just over 10% battery
I found it better just to buy a bigger battery because the loop ran better
That was using the Pi2
Not sure about other Pis

I think the sparkfun edison setup is a good option for portable without heavy soldering (you do need to solder the battery if you want over 850mAh, but that is fairly simple.
Scott Leibrand
@scottleibrand
Mar 16 2016 19:54
@TC2013 there are several people in the https://omniapsslack.azurewebsites.net/ channels who are working on various #machine-learning and #ode techniques that would be applicable to a basal tuning tool. you should jump in there and discuss as well.

with the sparkfun and the 850mAh battery you can also add an external power bank plugged in via USB to skip soldering entirely

true.

Jim Matheson
@jmatheson
Mar 16 2016 19:56
i think v1 could be with the 850 and the external battery and v2 could be to solder on a bigger battery instead to save more space. that is basically what i did.

Does anyone have any suggestions on what to do with a “free pump”? Meaning i am out of warranty on my existing pump, so i can get one from insurance. Was thinking I should take advantage of that. Not sure how supplies will come into play if it ends up not being a minimed. Would be great to have a ping or something that might end up working with openaps at some point in the next couple of years.
Ben West

Mar 16 2016 20:25
question went up some kind of chain, and back down... means they had some meeting and stuff to at least talk about it
yeah, there's a document that describes how to communicate and transfer data with the pump
commonly the document describes the "communication protocol"
but I commonly talk on the phone about the information needed to communicate with the pump
so "my software can talk to the pump"
now we have specific examples like Nightscout and openaps

one way I frame it is: "I looked through the manuals but the information needed to communicate and fetch data directly from device is absent"
they often want to tilt conversation towards future features/products
but issues isn't about features, it's "how can we resolve the problem of missing information?"
usually when it's over, I try to emphasize that access to data like this is going to be driving issue in sales (wishful thinking?)

I know that the most experiences exist with the old Medtronic pumps and I used a Medtronic Veo from 2010 to 2014, but I don't want to go back to this system

the big issue with the Ping is that you can't do a 0 temp for a short period of time, you're only option is to suspend the pump, but if your system fails you could wake up in dka
so it takes reliable monitoring, etc

Mar 16 2016 20:56
I think we need to split up the different pumps based on their capabilities, and ask the manufacturers for different things depending on what they can already do.
For the Ping, for example, we should ask them for the communications protocol (and list of supported commands), because we know it can do most of what we need, and the protocol / command list might have a way to do temp basals, even though the remote doesn't do them.
But for the Vibe, what @Surferin did as far as asking for features in new pumps is probably the best we can hope for.

But, did you hear about the Cellnovo Pump?
It will be a pump which works with a remote, on a separate screen and on the computer
And it will be a Patch Pump and a Pump with an infusion set
it seems as this pump system will be on the market probably next year or so
It's a pump from Wales, UK
Perhaps this might be a pump which can be used for openAPS in the future as well
Ben West

Right now diabetics in UK test the pump

Hi Everyone, I just got started with OpenAPS on a Pi 2 with a Dexcom G5 sensor and Medtronic 723 pump. The pump with a Carelink is working great, and I'm using the G5 receiver via USB and it's connecting. Problem is that when I try to read data it fails with dexcom_reader.constants.CrcError: Could not parse EGVRecord. I noticed posts on this Pull Request (bewest/dexcom_reader#1) but it doesn't work after patching the development branch and it's detached from the openaps repo. Is there any work on this, or how can I begin debugging the read process and contribute? I'm an experienced developer but I'm typically in the windows world so Python isn't my strong suit

@Surferin well the pump looks nice: invisible. many nice words but I dont see any CGM and the way how they intend to achieve it. May be they will tell later. Furthermore I would like to hear about a pump, which not just delivers, but also monitors, whether the proper amount is delivered (linear monitoring system).
Britta
@Surferin
Mar 16 2016 22:30
but it may be possible, to use this Cellnovo, monitor the glucose levels with Dexcom for example how lots of people do it right now, if you get what you need from the company to programm it for Open APS?
I, for example now use the Animas Vibe and the Dexcom CGMS G4 System without Share, but with the DexDrip alternative System. I don't use the Animas Vibe to monitor the CGM levels. I know that the Vibe isn't possible to use with OpenAPS, but if now I would use the Animas Ping System, I also would use the Dexcom G4 System with DexDrip and probably monitor the OpenAPS with HAPP or something like this

usually, when we get the documentation that explains how to exchange data with the pump, we can figure out some way to make it work
it all hinges mostly on having access to the knowledge of what the pump can do and how it works
unfortunately this information is missing from most manuals
Britta
@Surferin
Mar 16 2016 22:46
I hope that it may be possible that you get the documentation you need from Cellnovo when the pump is on the market at the end of this year or next year

@dpiessens Hi, good to meet you. @amazaheri is the only other person I know that uses the G5, but I think they don't connect via USB to the receiver, but rather use @bewest's https://github.com/bewest/share2nightscout-bridge to pull data from Dexcom servers into NS
Sorry, so not a solution but a work around of sorts
Britta
@Surferin
Mar 16 2016 22:55
Take in to consideration there's another pump coming onto the market from the Netherlands called Kaleido. Yes, it does not have CGM on board as well, but as with xDrip and Dexcom G4, it may be possible hopefully to use OpenAPS as well with it if you are able to get the documentation from the company: http://www.hellokaleido.com/healthcare-providers/?gt=sb_1

jam cylinder into the motor chamber, and it primes the tubing, mechanically
snap the controller onto the motor train, and it's good to go
motor portion is disposable with insulin cartridge
change sites as needed, change reservoir when the vial runs out

yeah, yeah you are right, I understand, hmm sounds interesting. cheap to manufacture
but on the other hand, if one prefers (long lasting quality and being certain) I like measure deliver measure closed loop control
at least a cylinder, where you can check one unit, is one unit in the glass
sorry in the cylinder
did you try asante, what was the price in the us?
Ben West

they had some interesting firmware that would consider your suspended time into your IOB/missed basal
or rather, they had a notion of "missed insulin" due to suspended pump, etc...

here, they say, that Animas is the pump which is dosing the insulin as accurately as possible
Ben West

they also handed me the documentation for the protocol
but it had no wireless :-(
I think if they had wireless, they maybe would not have gone out of business
they launched right when NS became popular
if they had wireless, I could have integrated it with NS right at the beginning
