| rjeffries | wpwrak would sense to add anelok in the description for this channel. More a focus that Ben NanoNote these days | 04:06 |
|---|---|---|
| wpwrak | psst .. not so loud. you wouldn't want to scare my internet connection. | 04:30 |
| wpwrak | for it's a shy and fragile thing ... | 04:30 |
| rjeffries | Ok | 04:31 |
| 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 :) | 04:33 |
| kyak | sudo topic :) | 04:39 |
| wpwrak | whee ! thanks ! :) | 04:40 |
| DocScrutinizer05 | ?? | 04:41 |
| DocScrutinizer05 | ooh anelok | 04:41 |
| rjeffries | what is this Ben Anelok of which you speak? | 04:42 |
| 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 | 04:42 |
| DocScrutinizer05 | fair enough | 04:43 |
| 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.) | 04:44 |
| rjeffries | Double A is looking better and better | 04:45 |
| 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. | 04:46 |
| rjeffries | nods | 04:46 |
| rjeffries | One could conceive of industrial design of case that is round on bottom. might feel nice in the hand. | 04:47 |
| wpwrak | overall volume would go up by some 20%. not horrible, but every cubic mm counts | 04:48 |
| wpwrak | hmm, i think it would be more like a wedge | 04:48 |
| wpwrak | save some mm by not having the PCB under/above the battery | 04:49 |
| rjeffries | nods | 04:49 |
| DocScrutinizer05 | that might actually look nice and ergonomic | 04:52 |
| wpwrak | and hell to make with my mill :) | 04:52 |
| DocScrutinizer05 | that too | 04:52 |
| DocScrutinizer05 | you obviously need a whole new case concept for that | 04:53 |
| 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 | 04:53 |
| 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 ... | 04:54 |
| DocScrutinizer05 | hmm, we need a sketch | 04:54 |
| DocScrutinizer05 | you lost me | 04:54 |
| wpwrak | wow, feels very weird. the behaviour of the slider chances quite a bit if you touch it with the side of the thumb | 04:55 |
| DocScrutinizer05 | since I'm poor at sketching, is it faintly like http://www.voelkner.de/products/38974/Pult-Gehaeuse-Hit-Pult.html what we're talking about? | 04:55 |
| wpwrak | yes, that sort of shape | 04:57 |
| DocScrutinizer05 | looks ideal for placing on a table | 04:58 |
| DocScrutinizer05 | I know the size and weight is so small it gets tricky with attached cables | 04:58 |
| wpwrak | anelok is more the hand-held type. and yes, if you connect a cable, the cable rules, not the inertia of the device :) | 04:59 |
| DocScrutinizer05 | anyway that shape of case seems pretty feasible even with your mill | 05:00 |
| DocScrutinizer05 | just the concept of 2 quasi-symmetric halfes would have to change | 05:01 |
| DocScrutinizer05 | rather build it similar to what's shown in http://www.voelkner.de/products/38974/Pult-Gehaeuse-Hit-Pult.html | 05:02 |
| DocScrutinizer05 | regarding shape of parts | 05:02 |
| wpwrak | (inertia) 18.2 g :) but with some extra cables that wouldn't be in a "normal" device | 05:03 |
| DocScrutinizer05 | up to you if you make the flat part the bottom or the display | 05:03 |
| DocScrutinizer05 | 18.2g suffice for a USB plugged to center of "backside" | 05:04 |
| DocScrutinizer05 | T | 05:04 |
| DocScrutinizer05 | might even work for 90° angle USB plug and L | 05:05 |
| 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) | 05:05 |
| wpwrak | see also http://anelok.com/test/ | 05:05 |
| DocScrutinizer05 | ooh, then no problem | 05:06 |
| DocScrutinizer05 | prolly even better would be jack on left or right small side, with a mandatory 90° plug cable | 05:21 |
| 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. | 05:27 |
| wpwrak | but i wouldn't require 90 deg cables ;-) | 05:27 |
| DocScrutinizer05 | wpwrak: a straight cable will tirn you device along long axis | 05:28 |
| DocScrutinizer05 | turn* | 05:28 |
| DocScrutinizer05 | maybe you could put the USB to backside, next to left or right corner. Then you need straight cable | 05:29 |
| DocScrutinizer05 | AAA max length 44.50mm | 05:32 |
| DocScrutinizer05 | plus holder | 05:33 |
| DocScrutinizer05 | usb would add a ?? 5mm on top, 8mm? | 05:33 |
| DocScrutinizer05 | maybe you can find a way to mount it upright (tricky) then it's only a 3mm max | 05:34 |
| 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) | 05:34 |
| wpwrak | cable forces are not such a big issue. if they're inconvenient, then you just grab the connector | 05:36 |
| DocScrutinizer05 | please rephrase | 05:36 |
| wpwrak | AAA axis would be parallel to X axis. let's say Y = Z = 0 | 05:36 |
| wpwrak | then USB insertion movement would also be parallel to X, maybe Y = -10 mm, Z = whatever works | 05:37 |
| DocScrutinizer05 | a micro USB receptacle is deeper than wide | 05:38 |
| wpwrak | i.e., AAA would be "rear", then USB, similar to where it's on the Ben, then the thin side of the wedge | 05:38 |
| wpwrak | mmh, i don't think so. lemme check ... | 05:38 |
| DocScrutinizer05 | how wide is anelok now? | 05:39 |
| wpwrak | (in any case, depth is no issue) | 05:39 |
| wpwrak | see anelok.com/test :) | 05:39 |
| DocScrutinizer05 | I don't see any measures there | 05:39 |
| wpwrak | did you hover ? | 05:39 |
| DocScrutinizer05 | occasionally | 05:39 |
| DocScrutinizer05 | well it's easter, nevertheless | 05:40 |
| wpwrak | hover over the case and you get the measures | 05:40 |
| DocScrutinizer05 | aha | 05:40 |
| DocScrutinizer05 | you really should add tags | 05:40 |
| DocScrutinizer05 | visible tags to hover | 05:40 |
| wpwrak | micro-usb: depth 5-5.6 mm, width 7.5-8.8 mm, height 2.5-3 mm | 05:40 |
| DocScrutinizer05 | toldya | 05:41 |
| wpwrak | there's a reason why it's called "test" :) | 05:41 |
| wpwrak | you said deeper than wide :) | 05:41 |
| DocScrutinizer05 | oops | 05:41 |
| DocScrutinizer05 | right | 05:41 |
| DocScrutinizer05 | sorry, no coffee | 05:41 |
| 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 | 05:43 |
| DocScrutinizer05 | such "riser" board easily fixes into two slots in case | 05:44 |
| DocScrutinizer05 | just an idea | 05:44 |
| DocScrutinizer05 | I see anelok X = 67 mm now, AAA = 45.50mm max | 05:45 |
| DocScrutinizer05 | AAA dia max: 10.50mm | 05:46 |
| DocScrutinizer05 | HEY, you prolly even could use the very USB jack sleeve for minus/GND contact of AAA | 05:50 |
| DocScrutinizer05 | ;-D | 05:50 |
| DocScrutinizer05 | well, maybe the shape isn't ideal for this purpose | 05:51 |
| wpwrak | no, it isn't :) | 05:51 |
| wpwrak | and i wouldn't put the connector at X+ of the battery, but at Y- | 05:52 |
| DocScrutinizer05 | why? | 05:52 |
| wpwrak | think part of the wedge = battery. medium part = connectors. thin part = just PCB and thin stuff | 05:52 |
| wpwrak | s/think/thick/ | 05:53 |
| wpwrak | argl | 05:53 |
| wpwrak | the battery is already very long. adding somthing to make the assembly even longer would be bad | 05:53 |
| DocScrutinizer05 | I see anelok X = 67 mm now, AAA = 45.50mm max | 05:54 |
| DocScrutinizer05 | you're actually wasting space | 05:54 |
| wpwrak | i would then put the slider on top of the battery | 05:54 |
| wpwrak | so it would be on the long side | 05:55 |
| DocScrutinizer05 | that makes think end even bulkier, no? | 05:55 |
| wpwrak | not really. the slider is thin. else, i would have a lot of completely unused case surface | 05:56 |
| DocScrutinizer05 | ok | 05:57 |
| DocScrutinizer05 | sidenote on lanyard hole: not very suited for keyrings | 05:57 |
| DocScrutinizer05 | but then... | 05:57 |
| DocScrutinizer05 | I mean, for a ring the thing should be as wide as it's deep | 05:59 |
| wpwrak | no keyring :) | 05:59 |
| DocScrutinizer05 | ideally with rounded edges of the hole anyway | 05:59 |
| wpwrak | but a standard lanyard fits very nicely | 05:59 |
| DocScrutinizer05 | you want at least a 1mm radius there | 06:00 |
| 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 ;-)) | 06:00 |
| DocScrutinizer05 | exactly | 06:00 |
| DocScrutinizer05 | ;-) | 06:00 |
| 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) | 06:02 |
| wpwrak | i was too lazy to round the edges, though. but the nylon or whatever it is made of appear to be tough enough :) | 06:03 |
| rjeffries | wpwrak your "what if" discussion re revised case w/AAA rather than CR2032 is encouraging | 12:47 |
| rjeffries | looking at https://en.wikipedia.org/wiki/AAA_battery | 12:49 |
| rjeffries | one benefit is in AAA size is variety of batter chemistries available. | 12:54 |
| rjeffries | Lithium Iron Disulfide Li FeS2 has advantage of exceptionally low self-discharge if I understand correctly | 12:57 |
| rjeffries | http://gadgetsandgear.net/Data%20Sheets/Cn%20data%20sheets/FR03%20Data%20Sheet.pdf | 12:57 |
| wpwrak | hmm, seems that the nighttime internet curfew is beginning again ... | 23:14 |
