wpwrak would sense to add anelok in the description for this channel. More a focus that Ben NanoNote these days
<wpwrak>
psst .. not so loud. you wouldn't want to scare my internet connection.
<wpwrak>
for it's a shy and fragile thing ...
<rjeffries>
Ok
<wpwrak>
regarding adding anelok to the channel topic, well, if anyone does it, it won't complain. not sure if anyone actually pays attention to these things, though :)
<rjeffries>
what is this Ben Anelok of which you speak?
<wpwrak>
it has a nice "low battery" indication: the display flickers heavily, yet the device's power situation is still very far from upsetting the CPU
<DocScrutinizer05>
fair enough
<wpwrak>
(looking at the one unit that's been on battery power since march 28. still operational, despite a "standby" current of some 0.9 mA. it does seem to drain the 2032 about twice as fast as i would have expected. but then, 0.9 mA is pretty abnormal anyway.)
<rjeffries>
Double A is looking better and better
<wpwrak>
AA is very big. AAA may be necessary, though. but let's see. i'd like to keep the small form factor. AAA would add a bulge and also make it less symmetric.
<rjeffries>
nods
<rjeffries>
One could conceive of industrial design of case that is round on bottom. might feel nice in the hand.
<wpwrak>
overall volume would go up by some 20%. not horrible, but every cubic mm counts
<wpwrak>
hmm, i think it would be more like a wedge
<wpwrak>
save some mm by not having the PCB under/above the battery
<rjeffries>
nods
<DocScrutinizer05>
that might actually look nice and ergonomic
<wpwrak>
and hell to make with my mill :)
<DocScrutinizer05>
that too
<DocScrutinizer05>
you obviously need a whole new case concept for that
<rjeffries>
I'm thinking it might be rather cool. There's a high-end music player out recently that if memory serves, is packaged in a triangular shape case, nt sure why they did it
<wpwrak>
but yes, it may look fairly nice. not so sure about ergonomic. the current design is pretty good for two-hand operation. one hand would be an option ... ah, lemme try it ...
<DocScrutinizer05>
hmm, we need a sketch
<DocScrutinizer05>
you lost me
<wpwrak>
wow, feels very weird. the behaviour of the slider chances quite a bit if you touch it with the side of the thumb
<wpwrak>
(inertia) 18.2 g :) but with some extra cables that wouldn't be in a "normal" device
<DocScrutinizer05>
up to you if you make the flat part the bottom or the display
<DocScrutinizer05>
18.2g suffice for a USB plugged to center of "backside"
<DocScrutinizer05>
T
<DocScrutinizer05>
might even work for 90° angle USB plug and L
<wpwrak>
well, the connector is on the "front" side. actually has better mechanical properties (though it's there simply because that's how i could make everything fit)
<DocScrutinizer05>
prolly even better would be jack on left or right small side, with a mandatory 90° plug cable
<wpwrak>
with this form factor, that's not possible. i have the battery on one side and the antenna on the other. with a wedge, the AAA battery would be on a long side and i'd put USB on a short side.
<wpwrak>
but i wouldn't require 90 deg cables ;-)
<DocScrutinizer05>
wpwrak: a straight cable will tirn you device along long axis
<DocScrutinizer05>
turn*
<DocScrutinizer05>
maybe you could put the USB to backside, next to left or right corner. Then you need straight cable
<DocScrutinizer05>
AAA max length 44.50mm
<DocScrutinizer05>
plus holder
<DocScrutinizer05>
usb would add a ?? 5mm on top, 8mm?
<DocScrutinizer05>
maybe you can find a way to mount it upright (tricky) then it's only a 3mm max
<wpwrak>
usb would be at Y- of the AAA. since the AAA is very fat, there wuold be plenty of Z room for USB (USB is also fat, but now nearly as bad as AAA)
<wpwrak>
cable forces are not such a big issue. if they're inconvenient, then you just grab the connector
<DocScrutinizer05>
please rephrase
<wpwrak>
AAA axis would be parallel to X axis. let's say Y = Z = 0
<wpwrak>
then USB insertion movement would also be parallel to X, maybe Y = -10 mm, Z = whatever works
<DocScrutinizer05>
a micro USB receptacle is deeper than wide
<wpwrak>
i.e., AAA would be "rear", then USB, similar to where it's on the Ben, then the thin side of the wedge
<wpwrak>
mmh, i don't think so. lemme check ...
<DocScrutinizer05>
how wide is anelok now?
<wpwrak>
(in any case, depth is no issue)
<wpwrak>
see anelok.com/test :)
<DocScrutinizer05>
I don't see any measures there
<wpwrak>
did you hover ?
<DocScrutinizer05>
occasionally
<DocScrutinizer05>
well it's easter, nevertheless
<wpwrak>
hover over the case and you get the measures
<DocScrutinizer05>
aha
<DocScrutinizer05>
you really should add tags
<DocScrutinizer05>
visible tags to hover
<wpwrak>
micro-usb: depth 5-5.6 mm, width 7.5-8.8 mm, height 2.5-3 mm
<DocScrutinizer05>
toldya
<wpwrak>
there's a reason why it's called "test" :)
<wpwrak>
you said deeper than wide :)
<DocScrutinizer05>
oops
<DocScrutinizer05>
right
<DocScrutinizer05>
sorry, no coffee
<DocScrutinizer05>
anyway, a upright "riser" board for one of the battery contacts and the USB would result in convenient 3mm X width for the USB, heading to back of case which is higher than 8.8mm
<DocScrutinizer05>
such "riser" board easily fixes into two slots in case
<DocScrutinizer05>
just an idea
<DocScrutinizer05>
I see anelok X = 67 mm now, AAA = 45.50mm max
fengling has joined #qi-hardware
<DocScrutinizer05>
AAA dia max: 10.50mm
<DocScrutinizer05>
HEY, you prolly even could use the very USB jack sleeve for minus/GND contact of AAA
<DocScrutinizer05>
;-D
<DocScrutinizer05>
well, maybe the shape isn't ideal for this purpose
<wpwrak>
no, it isn't :)
<wpwrak>
and i wouldn't put the connector at X+ of the battery, but at Y-
<DocScrutinizer05>
why?
<wpwrak>
think part of the wedge = battery. medium part = connectors. thin part = just PCB and thin stuff
<wpwrak>
s/think/thick/
<qi-bot>
wpwrak meant: "thick part of the wedge = battery. medium part = connectors. thin part = just PCB and thin stuff"
<wpwrak>
argl
<wpwrak>
the battery is already very long. adding somthing to make the assembly even longer would be bad
<DocScrutinizer05>
I see anelok X = 67 mm now, AAA = 45.50mm max
<DocScrutinizer05>
you're actually wasting space
<wpwrak>
i would then put the slider on top of the battery
<wpwrak>
so it would be on the long side
<DocScrutinizer05>
that makes think end even bulkier, no?
<wpwrak>
not really. the slider is thin. else, i would have a lot of completely unused case surface
<DocScrutinizer05>
ok
<DocScrutinizer05>
sidenote on lanyard hole: not very suited for keyrings
<DocScrutinizer05>
but then...
<DocScrutinizer05>
I mean, for a ring the thing should be as wide as it's deep
<wpwrak>
no keyring :)
<DocScrutinizer05>
ideally with rounded edges of the hole anyway
<wpwrak>
but a standard lanyard fits very nicely
<DocScrutinizer05>
you want at least a 1mm radius there
<wpwrak>
naw, where would be the fun in that ? they have to be razor-sharp, with a diamond inlay so that they cut through the lanyard within seconds ;-))
<DocScrutinizer05>
exactly
<DocScrutinizer05>
;-)
<wpwrak>
the standard cell phone / camera type lanyards seem to fit nicely. i tried the one from my ancient garmin, which is the usual size (goes around the neck, not the smaller ones from cameras that go around the wrist)
<wpwrak>
i was too lazy to round the edges, though. but the nylon or whatever it is made of appear to be tough enough :)

wpwrak your "what if" discussion re revised case w/AAA rather than CR2032 is encouraging
