Finally got my order

I used white cloner, now I know I really probably shouldn’t but everything was working after installation 2 weeks ago. It was working very well after a day or two.
And only 4 days ago it was really hard to get it to work. I had to hold my hand near the reader very long and sometimes it worked. 2 days ago it stopped working at all.
I was using it at least 2 times a day.
Field tester is and was working and other keyfobs still work.
Readers I use are mainly

About xac set up,
Can I just connect it to the 12v power supply, and then use the output to power since led diode? I wander if this output was enough, or I have to use relay with it?

try definitely shouldn’t have, although that doesn’t explain the degradation of your readability.
Even the blue cloner would have been a better option…
Consider yourself scolded

anyway, moving on.

Yes just connect to 12v DC power supply ( car battery, wall plug rated at 12V DC) dont’ worry about:-
Current capacity or output
You dont need it for this test.

it has an operating voltage range of 9 - 15V
So if you have a 9V battery, you can use that for the test.
I’m going to give you basic instructions
If you are unsure or need more detailed, just let me know. It’s no problem. (also apologies if this is teaching you to suck eggs :egg: :egg: )

  1. get your power ( 9V or 12V)

  2. dont let the white wire touch the other wires (best to tape it down or out of the way)

  3. connect Black to negative and Red to positive.

  4. Your xAC is now “live”

  5. scan the fob it came with on the antenna.

  6. The Red LED should illuminate :bulb:

  7. if it doesn’t, get the master “key” (black disc) touch it to the antenna and within 3 seconds touch the fob to the antenna.

  8. wait ?5 secs? the try the fob again, it should illuminate.

  9. If it does, then, ( try this way for ease of use )

  10. put your master disk on work surface

  11. pickup your antenna with the opposite hand as your NExT

  12. Touch the antenna to the master disk and within 3 seconds touch the antenna to your NExT

  13. Wait 5 seconds

  14. touch Antenna to NExT

  15. Does the LED light up.

Please let me know if any part of this doesn’t make sense or work…

We will get there.

I had another thought whilst I was typing this, If the :snake: white cloner :snake: has put your NExT into T5577 the xAC won’t work as it is “looking for” EM*** hence (xEM access controller)

Anyway, give that a try and let us know how it goes.

by the way
have a read of this

Just as I began assembling xAC I have tested NExT once again, as I was doing ~2 a day and it started working now

I am happy but also really confused, if it will stop working again I’ll definitely post here.

It is strange, It sound to me like a coupling issue.
Have you used your xField detector to find the best orientation of your NExT and position on the readers you are using?

Yes and those sweat spots are hard to find with xField, but chip works in nearly every position.

For 1,5-2 weeks everything working correctly, 2 days working badly, ~4 days nothing and now it is working like in those first 2 weeks.

I have no idea what was that about. It’s now working with door readers and cloner too. Let’s just hope it won’t go away like that again. I’ll carry my keyfob deep in my bag for situation like that for some time.

And by the way, at last, I am doing xM1 and vivo today.

One question, is xM1 too big to go into knife edge? What’s your opinion.

I dont have anything in my knife/blade edge, as I’m saving them for flex devices, I’ll leave that over to others with it in that location to answer, I have seen there are people with xM1 in blade edge which is also 3mm, so as long as your anatomy is suitable, then I couldn’t imagine why not.

Do you recommend any other placement for xM1 than standard places? Or maybe do you recommend any other localisation for vivokey? Is arm, like in some video of installation on DT site (I think), good place. Top side just after joint near hand?
Or like that, that one seems good

I would personally be thinking about how I would plan to use it and what do I have planned for the future.

Put it somewhere easy to use if you will use it alot or if it is just a nice to have, put it somewhere that is still usable, but not somewhere that takes up valuable real estate for potential future implants.

So I had them done, I was asking now cause ofc I want sure if my idea was good :stuck_out_tongue:
Vivo in this place from photo
xM1 in standard place

Awesome, I hope you heal well.
Don’t get worried when you see Biliverdin and Bilirubin


So I have worries again, not because of Biliverdin and bilirubin this time tho

I most likely implanted my vivo too close to the bone and on top of that it moved under the needle wound, so now it half over the bone :confused:

I can’t get it to move, although I have tried, are there any special methods to move it further away from hand??

] is the chip
- is where bone starts
and bold line is where it should be, anywhere there.

Other one is perfectly ok

EDIT: I feel like I cannot move it cause it’s “stuck” at the wound side

I see what you mean. This is a tough call. It could be ok, but with a slightly higher chance of breaking if you smack your arm just right… Otherwise it will very likely slide and move out of the way in the event a large force pressed in from the outside. If you have any doubts of course, you’ll probably want to remove it and re-install it in a better position.


So volleyball is bad idea from now on. Right?

And moving when it’s already partially locked too?
It’s just “suffering from succes”, it’s healing too fast :confused:

no volleyball should be fine… i would say try to avoid getting hit on the arm with a police baton or steel truncheon or baseball bat… but I know you’ll be resisting arrest, grappling with ninjas, and beating up baseball players by this time tomorrow… so just be careful.


Thanks for answer, I’ll definitely change my schedule and start avoiding ninjas from now on.

And today LF next wasn’t working again…
I’ve tried on 2 readers…
If it’ll be like that when I come back home I’ll see if xAC works and if not something is wrong…

Oh seriously? So it worked, then didn’t, then did again, now doesn’t again?

Yeah, I am so confused.

It doesn’t seem to be moving or anything

Okay, So I stand to be corrected here, but since you are getting intermittent faults… (as I type Amal just answered you, so good timimg) in my mind ( could be wrong ) it is either something you are doing or not doing
There is a loose connection between the chip and antenna, which would be unlikely because it is cast in Resin
What did you try and “read” it with?
Did you try XAC again?

I had no time to try xAC this morning I’ll as soon as I come back, so in around 10h form now.

I was just trying 2 door readers that were working yesterday.

hmm ok… it sounds like a cold solder joint. Basically the wire we use is coated and the lead free soldering process used to bond the wire to the inductor input on the chip must be hot enough to burn the coating off the wire and make a solid electronic connection, but sometimes the solder process is too fast or the heat transfer from source to target is not efficient and you end up with a cold solder joint which works but the wire is just sitting in a pocket of solder and not mechanically bonded… so it’s literally a loose connection that will work sometimes and if you jostle or jolt it, can stop working… it’s very hard to test for these situations because often times we test and it works… chips that fail to work we consider failed and remove, but if testing is passed we ship it… and maybe that connection works fine for a while but after normal use it can become intermittent.

We are working on ways to test for this, possibly by x-ray examination, but we need the testing method to remain cheap enough that the cost to produce doesn’t skyrocket.

For now let’s consider the NExT defective. Reply to your order confirmation email with this forum link and we will ship you out a replacement. Sorry this happened :confused:
