- Return of the button cell! The project is now powered by a CR1216. It will not come with one so it can make it through customs, but they are common and inexpensive.

Now I think this is GREAT news, that COMPLETELY negates the earlier bad news of being unable to charge in the game cart slot.

Hundreds or thousands of injections, AND carrying a spare button battery is INCREDIBLY easy.

I've had my love-hate moments with my other dongles (SX Pro caps suddenly dying on me while on-the-go, and RCMLoader not holding a charge AT ALL). This option just COMPLETELY solves ALL those problems. Plus I've had several packages blocked by customs for having a battery, now I don't have to worry about that.

This news has actually me hyped all over again.

Agreed. From my point of view, the two best options would be
- supercaps on a DragonInjector that charges through the gamecard slot so I don't have to think about charging anything nor about replacing a non-standard battery
- standard button cell that I have to change once every a-long-time and that I can easily find anywhere on the market
So this button cell solution is one of the best.

That said, @stuckpixel on the Discord has found a way to control power of the gamecard slot which means I could now utilize it for charging as was originally intended!

And this would serve the other best.

A lot of awesome news!

Actually, can I ask how this works?
Is it done via .kip/sysmodule? That would lock out SX OS users though.
Or is it done via Homebrew/RCM Payload?

Or is it the holy grail, i.e. the dongle/card itself negotiates/handshakes with the Switch like a gamecart would?

If it's the last option, would it be too much to ask for a technical breakdown of the details? Similar to what you did when the cart-slot-charging problem first came up? Thanks.

@MatinatorX
Recently a new type of lithium batteries popped up. Forgot the name unfortunately

They are as thin as paper and absolutely safe to use. You can stab them and they will still work lol They are not cheap and have a little less capacity than regular ones but this is probably a perfect fit for this dongle.

Are you maybe talking about something like this? They are called LCB

ghjfdtg · Nov 18, 2018

Ah, yep. Exactly these. Thanks

Lithium Ceramic Battery gives better search results for anyone wanting to look that up.

I'm far from an expert on the software side of things, but @stuckpixel coded the solution and has created a pull request for libnx. https://github.com/switchbrew/libnx/pull/208

The code itself is here: https://github.com/switchbrew/libnx/pull/208/commits/7f2c3f7d3c9d9530ae117591a8e53902121b2ccc

I also have an .NRO file they made me so I can test it out.

Really awesome work by @stuckpixel all around.

They were able to determine that VCC for the game card slot is directly controlled by the X1 and has nothing to do with the card slot IC. The IC only handles card communication duties.

The pin is called GcAsic Power: https://switchbrew.org/wiki/Bus_services#Known_Devices

If you'd like to know more I would suggest joining the ReSwitched or DragonInjector Discord servers and asking them directly.

It's a great looking technology but I can't find them for sale ANYWHERE. I'd really like to know the capacity of this little guy: http://www.eenewseurope.com/news/ceramic-li-ion-battery-10x-thinner-solid-state-alternatives

If it's over 3mAh and doesn't cost a kidney, it might be a great solution for a rechargeable DragonInjector Version 2.

--------------------- MERGED ---------------------------

Should mention for anyone wondering, we have no more than 18mm x 18mm x 2mm to fit in the battery and all required PCB components, so the battery really has to be tiny. In addition to that, it needs to support a 10mA current draw and supply over 3V for the majority of it's life. Really narrows down the options! If I added all the time I spent looking at hundreds of pages of batteries for this project, by now I'm sure it could span a whole weekend.

Nothing about size though

Generally the 6 digit product code is an indicator of the size. I'm going to guess that one is sadly quite large at 0.8mm x 150mm x 190mm based on the mAh rating.

You can see a photo of a 151036 battery in the listing, which is 1.5mm x 10mm x 36mm, which also matches up nicely with the reported 22mAh of capacity. Even this battery is too big.

The search continues...

Holy moly! If you ever manage to get this thing working, I am your number one customer!
Well maybe not number one because many people wrote before me, but I will be purchasing this!

Asia81 · Nov 18, 2018

state of the project?
can it be purchased?

Waiting for latest PCB revision, then testing. It will still be a few weeks before you can buy them.

Colors! Green and black are guaranteed, the rest will come if there's enough demand.

Find yourself 50 more people that would pay for such an ~~abomination~~ attractive palette and I'll make you all one.

Strange, according to the server settings it's still active. I tested the link on the first post and it worked: https://discord.gg/PjhRPfJ

Let me know if you're still having issues and I'll create a new link.

Idk why this is happening.

Edit: Nvm, I pasted the invite URL into the discord app itself and now it lets me in.

Back on page 12 MatinatorX showed all the possible colors. “Skin” was a choice and a few posts down from here he made a render of it as a joke.
