I dont mind either
@amal How confident would you say you are that the lack of potting with the LED nails in the flexNExT was the cause for some of them failing? Iām just trying to gauge what the longevity for them looks like. Is there any major risk of them burning out or dying in the flexMN?
iām getting the chips ordered todayā¦ shipping to me may take some time considering customs etcā¦ hard to give ETA for this first batch, but for the 2nd batch I should have a better understanding. I may combine batches just because of shipping delays to be honestā¦ but weāll see how it sorts itself out. i am going to put a bit of an investment into the first chip purchase round and hopefully it pays off in batch 2, just so weāre not constantly behind on delivery.
very confident. unfortunately i have much less confidence that the resin potting will solve the issue. i hope it will, but no ideaā¦ weāre in uncharted territory still.
as for burning outā¦ no chanceā¦ i have had the same nrfc nail stuck to the bottom of my acr122u for months nowā¦ just being lit 100% duty cycle. no issues.
The best closest example of performance expectations would be the flexMT and so far I donāt think I know of any LEDs that have failed in the flexMT, only the flexNExTā¦ but that might not be accurate. I do know that if any have failed in a flexMT, the count is so low I canāt even remember if it has happened or notā¦ so that must be good right?

Is there any way to reenforce some of the connections with solder? Also, have you or anyone else performed stress tests on the nails to see if thereās is a common point of failure or anything?
The LEDs are the least of my problem, i love them with all my heart.

There may be, but then the labor becomes increasingly tedious. I think maybe another approach might be to sort out a flex pcb antenna that incorporates chips and LEDs and passives all on the board along with the antenna. Then I could extract the chip and solder it to the boardā¦ but thatās also a lot of a different kind of labor ā¦ up front labor ā¦ may still be worth it thoughā¦ just many projects on the table at the moment.
Also putting LEDs in on the same inductor does impact performance of both LEDs and chipā¦ so the end result might not be all that awesomeā¦ unless maybe two separate inductors were integrated into the boardā¦ so many things to exploreā¦ this is how ālittle ideasā turn into big jobs.
Simple enough question, figured Iād start a new topic
Since I havenāt seen this discussed specifically
Can / will there be a x series offering of the magic ntag?
I would be interested in this or even a flex wedge more than the flex disc shapes
I believe that the flexMN is already being offered in wedge form, it just wasnāt advertised as much.
Just looking at it from the perspective that flexās have a lot more difficulty finding an installer, vs a simple x series injector
I think @amal said the chip in the FlexMN wasnāt available in the form factor required for x series. Iāll look for that response and reply if I find it.
Found it! Here: SURVEY Multi-purpose xSeries implant!

not likely ā¦ the chips are only available in COB format (chip on board) and I do not have access to the bare silicon die required to make x-seriesā¦ grey market and all thatā¦ i donāt even have direct access to the COB chip makerā¦ itās one of those āi got a guy who knows a guy whoās got a guyā kind of situations.
once we get the chips in and can study them i think we can explore a narrow flex form factorā¦ maybe. depends on the chip capacitance and our antenna design possibilities.
Any update on when a possible disbatch date for these cool chips would be? I saw that there was another batch online for this round, so Iām not sure if weāre waiting on more people to order before production, or if itās already started.
Iād completely understand if weāre waiting on more people, Iām just quite exited in getting it installed as Iāve been able to find someone willing to do it and was hoping to get it in before mid February.
Iām still waiting for the chips themselves to come inā¦ dealing with grey market chinese vendors is proving to be just as irritating as ever.
Well thatās just how it appears to work isnāt itā¦ just got the magic ntag chips! Going to do some testing later tonight.

That is good news. Not that Iām in a hurry or anything, butā¦ I admit Iām impatient to have a working long-range implant in my arm again

Now that my flexMN has come in, Iāve been playing around with it a bit. I remember there being some discussion about the storage onboard, but I donāt remember the exact details about it, and when I emulate an NTAG 216, it shows up as only having 41 bytes of storage space when I read it with TagInfo and NFC Tools.
Is the chip itself just for emulation with no real NDEF capabilities? I feel like Iām probably just messing something up, but I donāt want to go down the rabbit hole if Iām starting at an incorrect assumption.

I assume you got yours already because you ordered it sans blinkies, is that correct?
Re storage space, it should have the actual storage capacity of a NTAG216. At least thatās my understanding.
