I’m a Type 1 Diabetic of more than 30 years. I’ve spent my life travelling, playing cricket, taking photos, and doing loads of things. I’m a technophile and think like an engineer, even if I don’t do a job like that anymore. In this blog, I pull together both the Diabetes and the Technology to try and determine what is really the “art of the possible”.


  1. I ‘ m a mom of a insulin dependent girl. I read the Medtrum article and I was really positive surprised about what I read. I’ m interested in to try this Type of pump, as my daughter are struggeling with allergic skin problems with her current patch pump. Do you know when Medtrum will start to sell there products? In the Uk or Germany ? Is it possible to inform us ? Thanks in advance, lovely greetings from Germany . Simone

    • As the article says, in the UK we were told September time and they are starting to trial with Clinics now. Other than that, I don’t have a great deal more information.

  2. Hi Tim, Ive been following as much of the info out there on openAPS and looping as I can find and hopefully Im on my way to building my first eddison rig with freestyle libre acting as CGM through a sony smart watch and nightscout.
    I was reading the section on this blog about a “Build event” I wasnt sure if this was planned for the future and where abouts it was planned to be located. It sounds like a great idea and I would love to attend especially to meet people that have experience using this kit.
    Kind regards Tom

    • Hi Tom,

      I believe you’ve found the registration details for the workshop, so I look forward to meeting you at it. There’ll be between 10 and 30 people attending, if everyone makes it. Good luck with getting everything together and enjoy looping!


    • I would also be really interested does anyone know when it will be going ahead.
      Thanking you in advance.

  3. Hi Tim,

    Excellent article, we are currently on a Cambridge (uk) trial for our 6 year old son and we are very keen to continue looping when it finishes. What system do you recommend for an active 6 yr old boy with the least amount of kit and easiest to work at school etc

    kind regards


    • I’d recommend joining the Facebook “Looped” group where people who have experience of using systems with children can advise you of their experiences. I use the system on myself so can’t really give you any feedback on use with a young child.

  4. Hi,

    We have been using freestyle Libre for a while now and recently heard about the Dexcom and were thrilled of the idea of CGM however we were floored by the price, way more than what we can afford. I recently came across a kickstarter project that seemed to be a great option and was wondering your opinion on it? The press release seems very promising http://www.releasewire.com/press-releases/gluconightwatch-launches-intelligent-bracelet-for-diabetes-control-on-kickstarter-968882.htm any thought would be appreciated as I am looking to invest.

    • As far as I can see, it’s no different to Miaow Miaow, BlueCon, who also offer readers of the Libre, and a proprietary application environment. There’s also the BlueReader, which is designed to work with the WeAreNotWaiting community. Other than a slightly different application, I’m not sure what you get here that’s any different to the other options, except that the other options are available to buy now.

  5. Tim,
    In your article “Comparing #Loop and #OpenAPS – Looking at how the algorithms work”, where did you find specific information on the algorithms?? So far all I can find is the code to look through and some descriptions.
    I am doing a giant code review of at least Loop for a project, perhaps OpenAPS as well.
    Thank you for your help.

    • Essentially, the same way as you. Going through the code, the documents and then asking questions of people as necessary. Never be afraid to ask questions…

  6. Hi Tim … I’ve been following your D tech reviews since I started Looping 3-1/2 years ago. I also run an active T1 blog, about research, living/eating and on Fridays, a feature about T1s and their pets.

    Somehow, I think I saw a picture of you with a dog or two? If so, would you be willing to share a bunch of pictures and a story or 2 of your furry ones?

    Many thanks … joanne

      • Hi Tim … let’s connect via email. joanne@TheSavvyDiabetic.com

        Also, I started a Looping support group last July with about 25 members in southern California … called So Cal Loopers on FB. Since Covid, we started doing Zoom presentation called Loop & Learn … our membership has jumped to nearly 800, now worldwide. We are a kinder, gentler, calmer version of Looped. We have found that a lot of people learn better by seeing/hearing than reading. A few of our admins do a lot of mentoring and build support. My interest is learning and supporting others. While Looped is great for those getting up and started on Loop, we are finding there is a great need for community and ongoing help with settings.

        Would you be interested in doing a Zoom presentation sometime? We generally run about 60-90 minutes, people watch on Zoom or FB Livestream or later video watch parties. We are reaching a lot of loopers.

        Your topic is whatever you’d choose. Feel free to join FB So Cal Loopers and take a look at the discussions and videos that we’ve done. We are beginning to edit the videos (taking out the “ums” and glitches).

        Please let me know your thoughts. Thanks for all that you do. AND YES, let’s feature your furry ones!!! (Check out my blog, http://www.TheSavvyDiabetic.com on Fridays)

  7. Hi Tim
    off topic but you might know and vitally important for us Libre 1 users.

    Do you kow if the Libre 2 being released next month is the original European version, the US version or some other designed to frustrate the “We are not Waiting” community?

    Do I stock up on Libre 1 or happily wait for 2?

  8. Tim,
    Thanks for running a great site.
    I use an old Medtronic/FSL/RL/AAPS loop but have been offered a new pump by the hospital. Any advice on looping with an Omnipod (gather Eros can do it but net Dash – until Tidepool anyway)? Also interested in what you know about the Medtronic 780. Cheers for the help.

    • There are plenty of people using the Omnipod Eros to loop with both Loop and AndroidAPS. You can’t use Dash yet, although there are people working on getting that resolved, although no ETAs yet.

      The 780G has a very strong algorithm, but does require use of the Medtronic CGM system, which is a bit like Marmite. Some people love it and others hate it. So far, those that I know who are getting on well with the 780G are very happy with it. I’ve seen far fewer complaints about it than there were with the 670G, so Medtronic must have done something right!!!

  9. Hi Tim,

    I love the name for your site ?

    I’m hoping to start using a pump soon, and I’m also using DexCom G6 currently.

    I’ve started using the Quin app to track my food so I wanted to ask whether you know of any pumps which could take food input from the Quin or a similar app? Would I need to go for some kind of DIY Loop system instead to get that integration?
