    Looks like it's a good time for a quick update then!

    As @Adran_Marit mentioned, V14 tester units are ready to go. However, I've finally found a solution to the things that bothered me about V14 and earlier. New V16 has:

    1) CR1612 instead of CR1216 means 33-60% more battery life, and I can use a 0.8mm thick board, which is what the Type C connector is designed for. This is made possible by...
    2) WLCSP35 package ATSAMD21. The size of this package, and a reduction to the size of other components, means all components can now fit on the top. Which means...
    3) Turnkey China assembly is now a possibility. With this design, building DIs should take half the time it would have with V14, but if I can't keep up, I can now outsource.
    4) Fully enclosed battery. Now, there is no possibility for a leaky battery to damage anything. Replacement requires removal of 4 Philips screws. Philips screwdrivers will be provided with each DI.
    5) Hall effect switch for reset button means payload switching is still possible, and is the only button you will see. Firmware updates can be done by plugging the DI into a computer and waving a small magnet in the top right corner twice. This also means a bigger button than before, and no plastic bits for them, which means...
    6) With no button plastic and 4 screws holding the PCB, the case has now been tweaked to suit injection molding, and the cost of molding has been reduced by 40%. This increases the chance the DI will one day be injection molded.
    7) USB VCC power is back, preventing battery drain while updating firmware.
    8) Maybe this is subjective, but I think the DI is starting to look less like a hobby project and more like a consumer device with V16.

    I know it's unfortunate to change things so close to release, since V14 was tested and working great, but this is a passion project partly designed to see just what I can accomplish. I can't be happy with V14 if a better design can work, and I don't want to disappoint anyone who buys a V14 with a new model so soon after release. The delays should be minimal, as the V16 boards are already being made, and the components are already in the mail. If the V16 doesn't work out, V14 is already working and will ship to testers. I have enough components and boards on my kitchen table to do a few hundred V14 DIs. I would not be turning away from them if I didn't think the V16 was worth it.

    You can get a look at the V16 board here: https://a360.co/2DSVQnH

    As always, the Discord server is the best place to keep up with updates.

    Thanks everyone for all the support! V14 or V16, it won't be long now!

    Question, have testers already been notified that they are testers?

    Yes, they have though there might still be a spot open. I suggest you message Matinator on discord to find out for sure though

    this battery, how long does it last if it sits unused?

    unless you're injecting like 5 times a day, a battery in the DI should last well over a year

    does v16 have recharging the dongle within the game card slot?

    No, ver 16 will still have a battery, which you will need to change out though but at over 1000 injections per battery it should last well over a year

    is the v16 able to update to such a state in the future? Like have an update that will allow you to charge the internal battery within the switch gc? If not that's okay too but I knew it was talked about but wasn't sure if it needed a new reversion.

    Really looking forward to the release of this project. It looks to be the most convenient and streamlined injector out there. The fact that it's developed in Canada also tickles me!

    No, this isn't possible as there's no battery this size that can fit properly. There a small chance I can fit a 200815 lipo in, but this is no longer something I'm pursuing. The cost would be double thanks to the lipo and associated circuity, and it would be impossible to ship with little to no benefit. Once the lipo was end of life, your DragonInjector would be too. It would also be extremely costly to be certified for sale in most countries. With the current version I can get CE certification easily and relatively cheaply.

    With the switch to a CR1612, it's expected we will see over 2000 injections on a single battery. That's 5 injections a day for a year. Even the most demanding users should have a few months of battery. The standby time of button cell batteries is measured in years, and leakage is the lowest among battery types. With these factors in mind, I really don't see any advantage to a rechargeable variant and it would come with considerable compromises. This is why I no longer have plans for a rechargeable version. The current V16 meets all of the design goals I had for the project. 20 years from now I want to be able to dig a DI out of the closet, pop in a fresh CR1612 and have it just work. :)

    CR1612 batteries are only like 2 bucks anyway. Even if you had to change the battery once per month (which obviously isn't the case) that wouldn't be a big deal.

    Matinator you are really getting amazing at this! The passion I've seen since I started following this project is amazing. Always looking for any slight improvements then ending up blowing my mind with how ambitious you are and just how much you have built this into such an insanely great project, from the small increments that bring it closer to your perfect design to completely reorganising when you find new ways to incorporate parts or better use space.

    Hell, even if I wasn't planning on buying one or two, I'd still be following your progress because it makes me happy just seeing how much love and ingenuity has gone and continues to go in. This update perfectly exemplifies that.

    Cheers ^^, the scene is incredibly lucky to have you. I hope you're having fun!

    Thanks, I had thought I joined a while back so I wasn't too sure what was going on. I appreciate it.
