That is the perfect chip combo for me, and having as a single implant is perfect.
But 33mm wide is, on my particular use-case, an invitation for disaster.
I could even think of a Stickman* form factor, depending on the final dimensions ofc!
a wedge HF, with a circle LF attached on top of it.
You have just over 2 hours to decide if you want to get one in this batch. Have a look at some flexNExT threads to see what blinkies look like (ideally after some healing)
Hah well, now I have so many people now suddenly coming to me just after closing I just opened another batch… really these are just about doing them in batches so the next batch is live now.
I’m asking so I can start getting in touch with Lassi to book an appointment for the dead flexNExT swap. As you know, it takes some planning as I’ll have to fly other there.
FWIW, if you wanted to combine the first and second batch to buy the chips in larger quantity and save money, I’m okay to wait longer. The other “first batchers” would have to agree to this also of course.
@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? I’m 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?
i’m getting the chips ordered today… shipping to me may take some time considering customs etc… 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 honest… but we’ll 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 we’re 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 idea… we’re in uncharted territory still.
as for burning out… no chance… i have had the same nrfc nail stuck to the bottom of my acr122u for months now… just being lit 100% duty cycle. no issues.
The best closest example of performance expectations would be the flexMT and so far I don’t think I know of any LEDs that have failed in the flexMT, only the flexNExT… but that might not be accurate. I do know that if any have failed in a flexMT, the count is so low I can’t even remember if it has happened or not… 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 there’s is a common point of failure or anything?
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 board… but that’s also a lot of a different kind of labor … up front labor … may still be worth it though… just many projects on the table at the moment.
Also putting LEDs in on the same inductor does impact performance of both LEDs and chip… so the end result might not be all that awesome… unless maybe two separate inductors were integrated into the board… so many things to explore… this is how “little ideas” turn into big jobs.
