sounds good, I should really do housework and that is what I took the ADHD meds to do
but unfortunately, I then fired up onshape
teal burrow
that's good (?) becuase I also didn't start doing housework yet
I didn't really find a material that I'm happy with for the DMLS Ti yet, I might need to start over on that one
let's add in some buttons
thorny reef
so then would it be possible to take this and integrate it into a casing?
delete the lugs, move it into the body
looks like the width might just be about right too
it's an interesting thought experiment at least
Apple Watch Series -2
(since there already exists a Series 0, and the iPod Nano 6G can be called the Series -1)
fallow tulip
ok this looks rad
I really like this

Now with the refraction fixed! And a sharper 
. Onshape found the issue in the refraction: there were two translucent surfaces exactly abutting, but they really needed to be slightly overlapping in order to stabilize the model.

That's great

Those look so good

these are a dream come true
I'll sell off some 3DS handsets to afford to buy one if I have to lol
I like that the watchface gives the apperance that the bezel does not exist
Is that Underground?
somber junco
Yeah that effect works really well on the trypophobia one IMO
oblique moss
if there's like an official wait list I need to be on somewhere I'll do it
somber junco
Oh wait these should work with the Duos too, right?
oblique moss
it sounds like maybe but that they might need modification
so it's best to go slow to find out what the most sustainable solution is
imo
because making these for OG Pebble 2s only... then there's a limited number of innards out there
but supporting the Duo would mean new potentially better availability for guts

can I share the image?
Yes, feel free.

ok thanks 😄

I expect these will work with Duo but have not tried yet.

Genius or madness? Might have just come up with a new way to post replacement buttons to minimise breakages.
This is a CNC router drill bit holder
paper flume
thats good idea if you have reliable source of those containers.
fallow tulip
Just need to find the right search terms on Ali express, or a UK supplier
Google picture search for the win
Cardboard boxes are cheaper but a lot are getting broken in the post. The buttons are very snappable
gloomy roost
FDM a cheap box?
paper flume
easy enough to design half of box with ribs that can be interlocked to each other
and only take minutes to print
fallow tulip
Ali express will sell me 100 for £12. So 12p each. Time/money trade off time vs a 3D printed FDM case
Plus possibly slightly more reusable than a bespoke case. Who doesn’t want to have an extra bit tube in their life??
I like my current cardboard cases as they are fully recyclable, so if I change it, would have to be non-single use
teal burrow
These arrived today.
[Hydraulic Press Channel voice] I think that titanium win, and ultrasonic polisher lose.
fallow tulip
What grit did you get? Surprised if 180 didn’t make a mark
Also, now I want one of those ultrasonic cutters those fit into
teal burrow
I got 180 up to 800. 180 did make a mark but it is eating the stick much faster than it is eating the watch.
The cutter is good. It’s not as good as the Wondercutter S which was the first such cutter I tried. But it’s not bad
fallow tulip
Best thing I’ve found so far is 120 grit, 240 grit and 400 grit dremel flap wheel sanders.
Like these.
https://ebay.us/m/OBeSYc
teal burrow
Yes, I am coming to the conclusion that there is no replacement for just time spent with tools in hand.
I tried these, which worked decently: https://www.amazon.com/Dremel-EZ412SA-Lock-Grit-Sanding/dp/B005JRJHKS?tag=bngsmtphsnus-20&linkCode=df0&hvadid=80882941400099&hvnetw=s&hvqmt=e&hvbmt=be&hvdev=c&hvlocint=&hvlocphy=86250&hvtargid=pla-4584482468139638&th=1
I wonder how deep the market is for, say, $1k Tibbles.
I think that is roughly what it would cost to make them.
fallow tulip
So, $100 with no polishing, $1k polished??
Was thinking that a case with screen and buttons would be preferable. So I thought about bulk buying a few hundred P2 cases from the VLA store. The lack of bulk pricing put me off somewhat. But £25 per case for a screen is a factor unless the screens are available some other way.
I could easily spend thousands on cases
versed kelp
you can get the screens but without the glass
at least I think you can, I've seen a couple of offers, I'm not sure if the connector would be the same
I assume if you are buying enough bulk, you could also get glass in the right shape to glue it yourself but that seems like quite a bit of effort
https://www.alibaba.com/product-detail/sharp-brand-LS013B7DH05-1-3-inch_1600346130226.html apparently a screen is 20 bucks if you order at least 100 of them
teal burrow
So, $100 with no polishing, $1k polished??
Maybe they could be $300-$500 polished, with good tools? I dunno, if it takes... two hours to finish them...
fallow tulip
Buttons cost £7 each (£28 set of 4), screen £25, unpolished Ti case £30ish plus postage on all of the above. Then time to polish and assemble. Easily over £150 a case or you don’t even cover costs & time
versed kelp
I wouldn't mind polishing it myself, though I'm not exactly a typical client
fallow tulip
Build your own pebble kit
Or “pay me my hourly rate and I’ll build it for you”
How do you bond glass to an LCD? Not something I’d considered doing before

Also if the margin is high enough on the rest of the thing, you can sell fewer than your MOQ of various things. So if you have a MOQ of 400 on the LCDs, and the LCDs are cheapish but you only expect to sell 40 of them, you can just eat the other 360...
teal burrow
How do you bond glass to an LCD? Not something I’d considered doing before
Liquid optically clear adhesive (LOCA). I think it is doable in a home lab but traditionally you'd get your glass / LCD vendor to do it for you.
teal burrow
I wouldn't mind polishing it myself, though I'm not exactly a typical client
Also, the beadblasted finish does not look bad at all.
versed kelp
I've done it to a ptr and it's currently in pieces because I've done it poorly
I will try again soon
versed kelp
Also, the beadblasted finish does not look bad at all.
I want it polished tbh, I do like the look of that more
fallow tulip
Mmm, just checking the finishes you can get in Ti. Getting it polished in the factory would be way cheaper than doing it myself. Min $10 per part for mirror finish, half that for brushed, but would have to order to see what the actual price is above that minimum.
teal burrow
Would it be any good?
fallow tulip
Can’t hurt to try it out. Order one in each finish. Compare

the dremel sanding discs seem to have worked pretty well up until now, and I keep wishing that they go finer in grit

I'm kinda obsessed. the contrast with the screen and band looks so slick!
if it were possible to print black plastic buttons it feels like it would mesh super well
lil nubbins
I really love it, hahah. Nice work!
fallow tulip
My plan is to make some PLA buttons, then cave and try out the TPU when PLA doesn’t work well enough. I hate printing in TPU.
sacred trail
Is it just not consistent? I've never 3D printed anything
fallow tulip
Annoyingly difficult to get it to stay stuck to the print bed, very hard ti get it to print with a tiny nozzle, and very dimensionally inaccurate.
My favourite sort of material
teal burrow
yeah, 'do you like clogging your machine and getting bubbles everywhere? try printing TPU!'
fallow tulip
Oh and hours of drying before even trying to print with it
For a 1 minute print of a tiny button I’ve written off whole days before. So I try to stick to mechanical options

Don't say that. I just ordered some TPU95 for my MK3S
fallow tulip
if you find some secret method let me know!
snow steeple
Hopefully I don't have too many issues, my model is pretty simple
snow steeple
But I do need a conductive adhesive that will bond stainless steel and TPU if anyone had experience with it
teal burrow
this is sage advice if I have ever seen it
teal burrow
Brought it up to an 800 grit brushed finish.
I think now it's ready to cut with some black polish.
teal burrow
oh that definitely needs more sandpaper before polish
it's not... bad...
but it's like a scratched polished finish now
teal burrow
brought it up to a 3000# sanded finish which I think is going to take a polish much better
teal burrow
yeah this i sgood
I used some cutting compound on it, maybe I should try some polishing compound also, but this is pretty decent
fallow tulip
Going to need to see pictures soon
teal burrow
as always, I am unhappy with the surface finish, and I can only see the imperfections, but maybe also only I can see the imperfections
COGS if I was to do a second one, knowing what I know now, is $40-ish for the shell, probably about 40 minutes - an hour of labor to polish it, and a few $ worth of sanding consumables
I need to get some buttons
versed kelp
it is a bit rough around the edges, it's certainly not as smooth as a machined part
teal burrow
surface finish in the corners is really tricky
on the other hand, probably you have enough information from the size of that screen to compute how wide and deep those scratches are
versed kelp
there is a keyboard there for size comparison too
no matter what, it looks beautiful
teal burrow
I'm thinking of a 18 to 25V ano fade diagonally across it?

70 - 90V would be nice too but I'm kind of too lazy to hook up the power supply to go that high

@fallow tulip ok what is the spec for the buttons that will fit this again?
teal burrow
more photos: https://photos.app.goo.gl/b4Sc6wf9Lg7ZcKhJ8
versed kelp
omg
fallow tulip
For buttons, either of these:
P44929 or P44995 on the cousins website. they do steel, gold plated or rose gold plated
Links to stainless steel ones:
https://www.cousinsuk.com/product/classical-drive-in?code=P44929
https://www.cousinsuk.com/product/regular-drive-in?code=P44995
First link (classical drive in) buttons are slightly shorter at 5.45mm, and should be easier to fit.
The regular drive has the same size button, but the surround means it needs the larger hole to be 4mm exactly, so you might need a reamer.
2mm is the case tube diameter. I also had to ream the case tube fixing on the case. If the holes aren’t round or are a bit too small, the button will get slightly squashed and be tough to press
Try not to break a bit in the holes, it’s very annoying to drill out steel which has welded itself to Ti (I did this on my “steel style” Ti case with a 1.5mm bit making the hole large enough for a pebble steel button)
Case photos are the first link
teal burrow
So it truly takes fingerprints like crazy.
(Also if you drop it, it gets dinged.)
I’m thinking of hitting it with some clear coat, and that should provide some protection and keep it from being such a fingerprint magnet. Really 2k clear would be the right thing but I don’t have any.
teal burrow
I masked it and gave it some 1k. It loses a lot of shine with clear coat. We’ll see when the clear dries and I can give it a quick cut and polish. Maybe high voltage ano would make it more resilient to fingerprints.
paper flume
wonder if can get titanium buttons so it can be adonized
fallow tulip
Gold plated buttons might look quite good with it
versed kelp
that could be fun
teal burrow
my people already tried adonizing a gold thing once, it didn’t go so well for them
(that’s a bilingual pun on your typo, I hope you enjoy it.)
versed kelp
that thing looks so good
teal burrow
The problem is that is basically any surface coating at all touches it, it fully dulls. In the third picture you can see that even a small fingerprint residue dulls it. I’m going to continue to experiment with other coatings I can apply.
teal burrow
wax is an oil and will have the problem of oil on the surface
paper flume
hmm ok
versed kelp
that does give me an idea of a wooden pebble
teal burrow
I am trying some SiO2 spray which is promising in terms of not dulling it but may not be promising in terms of repelling oil
the other thing to try is bringing it up to a higher voltage, which is a thicker oxide and therefore less affected by oils
ok apparently the ano layer is… 20nm thick
that is not much
teal burrow
SiO2 might be the trick
oblique moss
ok here’s some video that starts to get the point across
Just stop
You're going to kill me

my p2 buttons are looking a bit worse for wear
fallow tulip
Dye won’t work, too patchy
versed kelp
aw
fallow tulip
Might try ink next
and cleaning up & polishing the model first. Suspect any finish would wear off though
versed kelp
print the case and then create a silicone mold of it, and cast it in translucent purple resin
ez
fallow tulip
I added a purple one to the order
the thought of casting these in resin is not something I fancy taking on. do have purple tint and resin in the house though for river-table woodwork
versed kelp
yeah, that's totally understandable

you can tell I have an impeccable taste

resin casting is not the end of the world to do
I was considering putting together an investment casting / lost PLA casting setup

The Italians (watch pusher button suppliers) are all on holiday until end of August, so will be September before I find out their prices

I don’t hate the shape of this one

I do kinda miss the small circular shape under the buttons tbh
fallow tulip
Wanted to try the case without them, but yes I also prefer it with the extra frame around the buttons
Direct side by side with a P2

my buttons should come tomorrwo
fallow tulip
I ordered some more too since the Italians are on hols
teal burrow
Eric suggests we should just ask Sharp if they have any more displays with the flex we want
and offered to put us in touch with them
it would still be on us to get cover glass + OCA in that case, but it would mean we could get whatever cover glass we want

that would mean we could make completely new watches 👀

ooo, a vise
fallow tulip
Or the diy version
#1345366437870567516 message
teal burrow
yes DIY version is what I want
aha, with channel locks would work
is it possible to remove them with the DIY version? or once they're in, they're in?
fallow tulip
You can push them out, you’d need the equivalent of the opposite side of the red vise. A pin to push from the inside (less than 2mm in diameter), and a loop the other side
Plus make sure the hole is as close to 2mm round before even attempting to fit the buttons.
teal burrow
do you use a 2mm drill bit for this, or a reamer, or something else?
I was wondering whether you just press fit them and let the buttons do the work, or whether you clean the hole up first
fallow tulip
2mm drill might be ok, reamer would be better, just be very careful and do it by hand, not using an electric drill
Don’t want to block the hole by breaking the bit in it
A 2mm diameter diamond file also works
The holes on the cases I received were slightly not round.
teal burrow
2mm diamond file is a good idea, and is much cheaper than a reamer
paper flume
if precision is needed, you might want to make holes smaller, but within reamer cut ability
so at end its nice precise bore
teal burrow
well okayyy I guess I don't get to install the button today
teal burrow
oh I do have a pin vise with a 2.0mm bit
but I assume that the bit is made out of extra sharp cheddar cheese
fallow tulip
Try just a piece of 1.75mm PLA filament. See how small the holes are. You can also check the button heads will fit upside down into the 4mm outer holes (I had to enlarge one of those too)
teal burrow
the button heads seem to clear well
ok, the pin vise with the 2.0mm bit does seem to clear as well
I think I am going to one more time tear down the finish and clean it up, to fix the spot where I dropped it, before I press any buttons in
fallow tulip
I hope the holes aren’t actually too big!
teal burrow
I plan to use a small amount of lithium grease in the holes to assist in any remaining waterproofing problems from uneven holes
I tried pressing the buttons in with my finger and they don't have a hotdog-hallway fit at least
teal burrow
ok I have a plan with the stuff I have here
it is going to involve a C-clamp and some printed stuff
teal burrow
the tolerances on these buttons are insanely impressive
fallow tulip
How’s the button fitting going? My new buttons have arrived before my new cases
teal burrow
Button fitting was ok but I decided to tear it down and refinish it one more time before I assemble buttons on it
teal burrow
I spent some time with Mr. Grabby-Throwy and finally got a surface finish I'm decently happy with.
versed kelp
so shiny you have to wear a shirt around it
it does look beautiful
I would love to do that to a titanium case
teal burrow
(for those who do not know the reference)
versed kelp
that it very funny
teal burrow
@fallow tulip I asked my friend who is an Actual Mechanical Engineer Specializing In Manufacturing if it was possible to get some tools cut for stamping a rear case, and, like, stamp some Ti cases at home with a dead blow hammer. The answer is apparently an emphatic no. In the volume one might think about it for this, one would wish to just get them milled.
fallow tulip
Fair enough. Milling’s a good option
teal burrow
I was thinking a version with like m1.4 screws holding the rear case on would be cute
thorny reef
oooo yesss a Pebble casing with screw back design would be a nice repairability upgrade
fallow tulip
It’s feasible. The pogo pin charger insert is do-able, as is a proper gasket and screws if the case is made a little larger to cater for it
oblique moss
that's very shiny
teal burrow
ok, re-ano'ed it, SiO2 coating is curing up, so it'll be ready for buttons tomorrow
oblique moss

I'll take pics once I put buttons in. it looks basically the same as last time I ano'ed it, but slightly less smooth because I learned the ahrd way this time that you really need to always start in the solution when you do a dip to fade

have you tried a 2 duo in any of these?
teal burrow
this one is going to get a 2 Duo's guts
teal burrow
wow disassembling a 2 Duo is a huge pain in the ass in a bunch of ways
paper flume
its similiar to pebble 2, glued and all?
teal burrow
here's my recommendation for how to disassemble a 2 Duo:
- The rear adhesive is a lot fresher and stronger than it was on Pebble 2. Use heat, and be patient.
- To avoid blowing anything up, activate the battery's protection circuit -- use a tweezers to short VBAT to ground. (You'll recover it later when you plug it into power for the first time.)
- Desolder the LRM. It's glued into the midframe pretty good and you're not getting it out.
- Bend the tab up on the edge of the LRM; it interferes with the PCBA.
- Use a guitar pick to remove the battery.
- Unscrew the three screws and remove them.
- Use a tweezers to liberate the bottom of the board, where the silver screw was, and then work the rest of the PCBA out. Bend the LRM up as needed.
- The backlight diffuser / antenna assembly may be glued to the screen -- be very careful to avoid delaminating it. The BLDA from a Silk should be compatible, but note that the midframe stamping has changed to support the new LRM. (You could probably use the old midframe/ERM if you want; it would require some firmware changes but I guess we can make those now.)
- The board appears to be fragile in ways that are surprising to me. My first attempt seems to have subtly killed the SPI flash.
paper flume
battery is removable?
sounds like besides frokm previous steps, its easier to swap batteries
teal burrow
same as before, it's glued down and soldered in
the midframe and BLDA is fighting me a lot more than I am used to though
the BLDA was glued down and I thik I wish I had gone in with some isopropanol first. it might not have survived
I will probably go grab a BLDA from a silk
man do I always hate the 'take a deep breath and believe in yourself' step of using the P2 Popper

@fallow tulip I think the alignment notches for the subframe on the single-butotn side need to move ~0.2mm north on the watch (or, to be safe, be 0.2mm shorter on the south side)

something really weird seems to have happened to the flash in the transplant
thorny reef
here's my recommendation for how to disassemble a 2 Duo:
* The rear adhesive is ...
What are these acronyms? Like, what's an LRM and a BLDA?
thorny reef
LRM: linear resonant motor
I'm guessing this is what the new watches have in place of the old vibration motor?
I've heard the new motor is weaker than on older pebbles
teal burrow
yes, the old thing was an eccentric rotating mass
thorny reef
wonder if you could "retrofit" the old style motor for a stronger buzz
or is the arrangement/packaging different?
paper flume
isnt linear one far stronger vibration?
teal burrow
I'm not sure about the packaging
thorny reef
isnt linear one far stronger vibration?
From Eric's latest blog post:
"The vibrating motor isn't as strong as I'd like it to be. It's quieter than the old motor for sure. We may be able to improve this in software by adjusting the vibration pattern."
paper flume
hmm ok
I guess quieter as in less vibration, rather than audio (techinically same thing but yeah)
teal burrow
well, the good news is:
thorny reef
oooo I didn't know the logo was different, that's cool
teal burrow
the bad news is that something really weird happened to the flash in the process of the transplant. no idea what. I have one more spare. I might try going in and reflowing it first but who really knows what's going on in there.
it sure does look good standing still, though.
haha the flash is getting quite hot too
thorny reef
haha the flash is getting quite hot too
I wonder if a capacitor or something got knocked off the board?
teal burrow
I don't see anything visually wrong, I expect it was a short during disassembly
thorny reef
I remember I had this iPod once, long time ago, that had some sort of board issue where it would function fine, but the board would get piping hot during operation
especially the chip/ram area

<@444751894267691019> I think the alignment notches for the subframe on the sing...
I think I’ve already done that on most of the models. I’ll check the one for your case
It really does look stunning, but that disassembly sounds awful
teal burrow
it's definitely worse than a normal silk, though now that you know what to look for it's more survivable
taking a silk ERM + midframe might be a reasonable choice
fallow tulip
Eccentric rotating motor?
I need to practice my soldering
I like your button fitting jig too
teal burrow
ok, trying again. I'm going to try... being more careful this time.
teal burrow
this time it works!
I think I might have killed the vibe motor though, ugh. or not soldered it well. or shorted it or something. I do have one spare midframe that I can swap through. but boy do I not want to.
teal burrow
ok we're going in for one last swap before I seal it up I guess.
it ohms out correctly...
teal burrow
ok I think I melted the ERM on the old one or something
ERM works this time... and I didn't get the LCD cable hooked up this time...
teal burrow
ok I cannot really seal this up because the bluetooth antenna is absolutely fucked
with the back on, the bluetooth range is about 7 inches
I think the problem is that there isn't the screw in the bottom that applies clamping pressure on the antenna
in the open, sitting right next to my phone, I get about -85 dBm; if I take a guitar pick and press hard on that screw hole, I get about -50 dBm
it might be good enough to add a piece of copper foil there
thorny reef
I wonder if the fact that the case is entirely metal may also be a factor
teal burrow
it definitely does not help
though the big problem is the like 0.2mm gap between the antenna and the antenna contact, if I had to wager.
fallow tulip
What’s the antenna and where’s the gap? Is there something slightly off about the case dimensions
It looks gorgeous
teal burrow
the antenna is on the bottom of the backlight assembly. let me highlight it in cad
here is the antenna clip on the mainboard
here is where it touches the antenna, on the backlight diffuser assembly
I think the problem is that the midframe is not fully sitting down
also, this screw is supposed to provide clamping force, but doesn't due to the nut in question not existing
teal burrow
update: I am printing a handful of M1 nuts in a spiral vase mode. let's see if I get away with it.
lol that worked way better than it had any right to
looks for his bottle of cyanoacrylate
I CA'ed one into the chassis that I'm putting together for @oblique moss , let's see whether I also accidentally CA'ed the screw in
if this works I am going to be super stoked
oblique moss
And?
teal burrow
it looks like it’s going to work but i’m letting it cure overnight. tomorrow I’ll disassemble my real one
teal burrow
yeah this will work I think. the printed nut definitely doesn't hold as much torque as the original case, but just be gentle assembling it and don't overtighten it
fallow tulip
I’ve modified the model slightly for the plastic ones, so allow the screw to go directly into the case without the tiny brass nut. Also works ok if you don’t over tighten, but it is a one shot deal
Was going to suggest a small piece of plastic instead of the nut, so very happy that worked

i am thinking about sanding the larger surfaces smoother
versed kelp

gleaming snow
i couldn't tell. it looks like i'd expect an SLS surface to look
it's.. rough textured
fallow tulip
It’s Mimaki Full Color Photopolymer. I don’t think the colour goes all the way through, at some point they save on colour by using white inside. Should be ok to sand slightly though
A vapour smooth with acetone would work too (they claimed the part was “too small” for Vapor smoothing but it was available for larger prints)
Shouldn’t be porous as it’s resin
versed kelp
can you add like tendrils to the print in each direction to not waste too much plastic but allow it to be vapour smoothed
fallow tulip
I could add a hook to it to allow it to be hung in a vapour chamber yes
That’s what a different company is doing in MJF and SLS for me
Leaves a small witness mark but that shouldn’t be an issue as it’s inside the case
gleaming snow
my cheapo digital calipers read a pebble steel button shaft at 0.8mm [diameter]

ugh, the plastic guy did not really do me any favors in the end
I think the answer is that I really do need to grind down the protruding bits on the one-button side to get the midframe to sit down

teal burrow
next time I say I plan to do something like using a broken-off drill bit in a dremel freehand as an end mill, please tell me to get some less stupid ideas, like punching myself in the balls repeatedly
ok this was... not a triumph
the plastic nut was not sufficient to hold the screw captive
and I think I have murdered another LRA
fallow tulip
So conclusion so far is that the P2Duo is less repairable than the P2
teal burrow
if you have to remove the mainboard, yes
battery replacements are roughly the same
a lot of my chaos has been because I am trying to put it in a frame where I don’t have the right fasteners and it doesn’t quite fit, though
thorny reef
sounds like cases will need some tweaks then for 2 Duo
teal burrow
fallow tulip
sounds like cases will need some tweaks then for 2 Duo
It’s more that metal prints are less forgiving and need tweaking. I had to grind quite a bit of my Ti case too, but the same plastic case fit much better, possibly because the plastic was also in the wrong place, but deformed/broke off
thorny reef
interesting
fallow tulip
Tiny M1.2 nuts were my workaround for avoiding tapping a thread in Ti.
teal burrow
oh I have more prototype midframes, woo
fallow tulip
Glueing the nut in is fun. You’ll probably find it’s also in slightly the wrong place, maybe .1 or .2mm out. But brass is forgiving
I should do a model diff picture and you can check if I’ve fixed all the slightly wrong inner lugs etc
teal burrow
yeah I found it was in slightly the wrong place also...
I was going to get stainless since it's what I could find

I think the next rev of Ti2 units probably should be designed for screw-on rather than glue-on backs
fallow tulip
Reuse the existing backs and cover them, or fully replace? If so, I need to figure out the charging pogo pins
You want an actually waterproof watch
teal burrow
I would like to mostly fully replace, but there are plenty of cheesy options, like milling the pogo assembly out of the existing plastics and embedding it into a Ti2 assembly
I do want a waterproof watch, but mostly, the glue is a huge maintainability problem for how often I seem to fuck up assembling it
it's possible the pogos could be done on a stiffened flex from jlcpcb or something though and recreated or something? or on for that matter a rigid PCB?

fallow tulip
I am very jealous of that watch
sacred trail
It's absolutely gorgeous! Nice band choice, also
oblique moss
Wow!!!!
teal burrow
well, the good news is that a man with tiny nuts has arrived at my door
unfortunately, his nuts are still too big to fit
also, while holding the fastener in question with my tweezers, it then launched into orbit
teal burrow
the fastener really does seem to have a 1.16mm major diameter, why did it not screw into the M1.2 nut?
it seems to be about 2.35mm long
ok it does thread the 1.2mm nut
so now the chassis has to be modded to accept the 1.2mm nut
teal burrow
my nuts appear to be 2.52mm flat to flat, which appears to be well outside of the 2.15mm range that this thing was designed to take
time for some shrr-shrrr with the carbide burr I guess
yeah 2.5mm is the DIN spec
bluhhhhh
maybe I should try plan B, and model up a solid plastic element that goes in there, and then use a pin drill to clear the space to get the screw in
or plan... Q... at this point
another option: drive in a m1.4 fastener that might have a little more bite on the plastic that's already in there
driving in the m1.4 fastener seems to have made it at least usable
like it seems to pin the antenna in there
paper flume
maybe use surfical bolt, put nut on it, then grind it down
teal burrow
m1.2 is insanely small haha
paper flume
hmm you got them priming lines from 3d printer?
may be able to use it as plastic bulk for bolt to bite into
teal burrow
there is no grinding to be done here that can really solve this
anyway, plastic plus m1.4 seems to do the trick
now I just need to figure out the other alignment problems on the thing when I replace the midframe for the fifteenth time, but that also will be solved with the carbide burr
versed kelp
what size nut would fit in that hole, m1?
versed kelp
I cannot fathom m1 because m1.2 is already so tiny from my experience
paper flume
smallest drill I ever used for production parts was around 0.8 mm. it was drilled 1.4? cm deep
which is very deep for that tiny dia
teal burrow
yes, that is quite an aspect ratio of cut
versed kelp
0.8 is the diameter of ptr springs!
if you drop that thing on the floor, it's fucking gone
paper flume
its also tapped, and I had to clear chips out of every hole, which is 4 per part
teal burrow
it seems like you would only barely get away with that with a conventional drill bit, it seems like you'd need like an EDM drill for it
teal burrow
if you drop that thing on the floor, it's fucking gone
yeah a few screws have vacated the premises already
paper flume

teal burrow
I found another three midframes around here with LRAs at least, so I'm not at a dire shortage
oh and I found the prying to do to get a LRA out of a midframe, so also good
versed kelp
I sure hope I don't kill my c2d trying to rehouse it
teal burrow
ok.
I think I am not going to try to mak eanother one with this particular ti design, just because it requires an enormous amount of tol stack fiddling to get it to work. but I think this time I have assembled it with four buttons that press (barely), and an antenna that I think will work.
@fallow tulip it is probably worth taking a look at the Silk step files and adjusting some placements of various features to align things a little tighter; I was thinking of doing some hack-and-slash editing of your step file to move features around and then I realized that, like, you probably could do it better than I given that you have the source
and I think it would be good to design it to take standard DIN size m1.2 nuts in the nut zone
either that or design a back plate for it that screws on using external fasteners and just applies pressure in the right place, which could solve that problem
hopefully it still powers up, and then if it does, I'll go harvest one final LRA and seal it up

but also I don't want to come back to it again later, so maybe I had better do it

the silk went together easily the first time with no issue whatsoever
the tol stack is just so much more finicky on asterix than on silk
teal burrow
ok it's being clamped together to cure. wish me luck.
fallow tulip
I’ve updated some/most of the models to match the silk case placement.
The latest batch of plastic cases have the new placement for everything except the nut so I should know in the next day or two how it varies for a few different materials. Then I’ll order another Ti case or two to see if they also print accurately
The brass M1.2 nuts I found are 2.0mm across the flats, so smaller than the DIN ones. Will see if I can either mod the file to fit a DIN nut or change the fixing entirely to a larger plastic one

are you going to do a run of those in Ti first? if so I’ll wait for you
if not I need to ask my friend Riley what he recommends for a tapped hole there. I think drilling and tapping it to m1.2 without the rigidity of a CNC mill is going to result in a case made mostly out of titanium with a little tool steel in it
it might also be worth trying to go to cnc for the whole case

uncut wren
Yeah the shrinkage doesn’t sound fun. That was one of the big reasons I never ordered any.
fallow tulip
Pretty sure I’ve solved it though. A new set of titanium ones will be on order soon if you wanted me to add one for you onto it
uncut wren
Yes please add me. Send me a pm or email and I’ll pay you.

I tried a tumbler. A dremel was much better for polishing. A bench polisher is even better
I might order a 3 lug Ti one and see if I can get a pin to fit
uncut wren
Good info. I may try a steel brush attachment. It would give the brushed look and sounds like something you have not tried. I also don’t care about shiny anyway.
uncut wren

Getting it to fit wouldn’t be terribly hard, but cutting threads into one side probably would be.
I purchased a tap and die set for this purpose a while back but the threads are sooo small who knows how well it would work.
Did you look into having the middle lug have a slit in it so a normal spring pin slides through that? We briefly talked about it.
Like it is open on the back side
fallow tulip
You could use a solid pin or a split pin instead of a threaded one
Like the ones on the strap links
More of a hassle to change, but doable
uncut wren
Yeah but at that point I would just do a spring pin. A split pin (also known as a cotter pin) looks too janky for my taste.

That’s the problem with the internal screw thread for the board too (the longer third screw). I’ve used a plastic insert to solve that
uncut wren
Probably would catch on everything too
fallow tulip
Solid pins exist too: https://www.cousinsuk.com/product/0100mm-solid-pins

Yeah I had scrolled up and was reading before you replied. Good solution. I think I have a good chance at tapping threads on the one lug like the classic has but who knows. All it takes is one screw up and that option dies with that case.
Yeah but what holds the solid pin in place?
Oh and I think we talked about instead of printing a slit in the middle lug, doing a solid 3 lug and me cutting a slit in the middle lug.
fallow tulip
Yeah but what holds the solid pin in place?
Friction
gleaming snow
you could probably tap the thread from the outer hole, right?
fallow tulip
The thread is M1.4 I think. It’s so small and Ti is so hard to cut
I do have some tiny standoff inserts. Might see if there’s enough room to use them in the strap lugs
They are M1.2 though
uncut wren
Yeah driving in a pin with friction isn’t the worst solution. Not like I would ever change a band anyway. And ohhh I did t realize you were doing titanium. Yeah my tap would not cut a thread into that. I was thinking they were aluminum.
fallow tulip
Ti is way nicer. Steel is really heavy it turns out (!) and Aluminium works ok but the prints aren’t as nice
uncut wren
you could probably tap the thread from the outer hole, right?
Yep, but you have to hold the tap perfectly vertical with no wobbling. So going through the opposite end would keep the tap straight.
uncut wren
Ti is way nicer. Steel is really heavy it turns out (!) and Aluminium works ok ...
Hmmm. Yeah it seems there are some additional negatives I had not thought of. The weight of steel is not a big deal but the hardness of titanium is a big negative. Aluminum would get banged up over time and if the prints are not turning out well then that kind of rules them out. Man, it seemed soooo within reach but now seems so distant.
fallow tulip
This is an unpolished aluminium one. I’m underselling the finish I think (I prefer Ti)
If you’re set on a three lug, I’ll sort you one out.
uncut wren
Yeah that’s not bad. Using a steel brush wheel on that would give the brushed look pretty easy.

you should try anodizing that!

Oh, but the one in the vid has round holes. You have a case with square holes for the steel’s square buttons?

Steel buttons on the one on the right
thorny reef
I think anodized red aluminum + steel buttons or classic buttons would pop
definitely probably might try that if I go down the case route
if I have money to burn
fallow tulip
I have burned a great deal of money already 🙂
uncut wren
I’m about to need to step away for a bit. If you have time, let me know what you have available for that classic steel look. Even if it is a later batch. I’m kind of leaning towards just putting the P2d in one of the plastic cases I have and calling it done.

for printing buttons, is PLA the go to material?
I also have ABS and 95a TPU

PLA is just fine

I’ve been tinkering with the Pebble 2 Bumper model to fit the new thicker P2D back plate slightly better. At the same time, I’ve been pondering extending the top to cover the watch strap a bit. What do you think?
At the moment a dark cover on a white watch or vice versa shows quite a bit of the original colour by the watchstrap lugs
Current bumper
Extending the colour further down & up would I think make the difference less noticeable
sacred trail
would extending create a spot where grime could build up? or am i misreading this visually
uncut wren
Did you ever play with making a bumper that incorporates buttons like we discussed? I still that that is the ultimate protection.
fallow tulip
I did but couldn’t get it to work. The flex you need to clip over the lugs means the button bit needs to be separate

TiSilk survivability update: my TiSilk powered off last night and would not power back on, including connecting it to a 5V supply.
I disassembled it and found corrosion not around the buttons but around the upper left corner, indicating a bad seal.
Buttons seemed basically pristine.

did you immerse it in water or something?

The battery was in a protect state: it read 0V until I gave it 50mA to wake up, at which point it came up to 3.65V.

I was going to spend some of this weekend on tweaking metal cases & ordering some more Ti ones.
Can’t do that though until I’ve figured out how many more bumpers I need to get printed to fulfill backorders.
(Nice problem to have, being sold out of stock.)
Also need to glue down my own watch case again. I noticed today that one corner was lifted slightly, fortunately before I did anything muddy wearing it.
teal burrow
fingers crossed that I didn't change the dielectric coefficients anywhere that it matters

How much of it are you smothering in nail polish?
fallow tulip
Good luck
teal burrow
one potential problem is that I may have had too much caffeine to get the LCD connectors seated again
fallow tulip
Yeah, a steady hand, and a small piece of sellotape definitely helps
Also an extra hand would help
teal burrow
it's alive!
what I do to seat LCD connectors: solder in the battery (on silk; can be done afterwards on asterix); stand the PCBA up on end; unlatch connectors; pre-stretch cables; use an EROP7SA to connect the backlight cable, then push it in; use the EROP7SA to close the latch; wiggle the PCBA down as far as I can, and grab the LCD flex with the EROP7SA; insert it; then walk back and forth from side to side on the LCD flex to insert it fully, and then close the latch; pray
the trick as always is to use god's own tweezers
time to absolutely fill it with B7000
this one even has a working HRM
fallow tulip
How I seat the LCD…
Same as you for the backlight
For the lcd though, I attach a small piece of sellotape with a folded over loop at one end to the cable. Use tweezers through the loop to help wiggle the connection in. Latch down the connector. Remove sellotape. Pray
teal burrow
if you don't have a pair of EROP7SAs, order some
fallow tulip
Gods own tweezers because they’re anti magnetic or really precise? Or both?
teal burrow
Both.
They're the right shape, they are extremely strong for some reason, and they are extremely precise.
They're strong enough to use them as picks, too.
And they're cheap.
