wpwrak | zrafa: hmm, better than nothing ... though not much :( | 00:19 |
---|---|---|
wpwrak | zrafa: as a first test, you could look at VDD and nRESET. trigger on nRESET falling. then see if VDD is stable. pick a slow time basis, something like 10 ms/div or slower. | 00:20 |
wpwrak | zrafa: if that looks okay, proceed with SWD_CLK vs. nRESET. see if the clock pulses appear and whether they have a good shape. | 00:21 |
wpwrak | zrafa: finally, you'd go to SWD_DIO vs. SWD_CLK, triggering on SWD_CLK. that will show you a lot of things ... if they stay on the screen long enough | 00:22 |
wpwrak | you really need to get a DSO for such things :) | 00:22 |
zrafa | wpwrak: I will try and let you know how our experiments go ;) | 00:41 |
zrafa | thanks a lot btw | 00:44 |
wpwrak | no problem :) | 00:52 |
whitequa1k | DocScrutinizer05: (putin) true | 01:14 |
whitequa1k | (mass media) no, they did better. they just destroyed whatever they could (all lenta.ru staff basically resigned) and then blocked everything else | 01:14 |
whitequa1k | there's a huge (government-known) protest scheduled tomorrow | 01:14 |
whitequa1k | today actually | 01:14 |
whitequa1k | I'm pondering going there but not quite sure. people were beaten and imprisoned for months before... | 01:15 |
nicksydney | DocScrutinizer05: might find this interesting http://gigaom.com/2014/03/14/holland-says-yes-to-the-network-agnostic-sim-card/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed:+jkOnTheRun+%28GigaOM:+Mobile%29 | 01:23 |
kyak | DocScrutinizer05: so you have your own opinion on Ukraine subject? That's great! | 03:16 |
Action: whitequark tries not to cry while watching http://thedailyshow.cc.com/videos/gtb1g6/csi--crimea-scene-investigation | 07:21 | |
whitequark | before you ask: I've checked and all the news fragments they're using are genuine | 07:22 |
whitequark | wpwrak: http://imgur.com/Cp2rUu6 any idea wtf is this? | 07:33 |
whitequark | also: http://imgur.com/hUoqSnb,sU97KK4#1 | 07:47 |
whitequark | wpwrak: also, those cheap .2mm endmills are worthless | 08:46 |
whitequark | the deflection is up to a millimeter. the head travels in a straight line at 10 or 20 mm/min, the end of the endmill travels in huge circles almost up to 1mm in dia | 08:47 |
Action: kyak doesn't cry at all while watching https://www.youtube.com/watch?v=iej-kuaN1Mg | 09:07 | |
whitequark | DocScrutinizer05: you'll like http://www.youtube.com/watch?v=e4mXLcQUixs&feature=youtu.be | 09:39 |
wpwrak | (bonus pack) luxury toothpicks ? | 09:52 |
wpwrak | try going MUCH slower ? | 09:53 |
wpwrak | i'm amazed that they survive 1 mm deflection. are they made of rubber ? | 09:53 |
whitequark | wpwrak: well, they were sold as HSS | 10:06 |
whitequark | keep in mind they're 4mm long and 0.2mm thick | 10:06 |
whitequark | 5mm long even | 10:06 |
whitequark | I'm a bit at a loss to who thought this is a good idea | 10:06 |
whitequark | or perhaps, I now understand much better why are they so cheap | 10:07 |
wpwrak | these are drills, not endmills :) | 10:08 |
whitequark | well, they were sold as endmills! | 10:08 |
wpwrak | at 0.2 mm, plan on a length of 0.5 mm +/- 0.1 mm | 10:08 |
wpwrak | (for an endmill) | 10:08 |
whitequark | actually | 10:09 |
whitequark | it is possible that you are right | 10:09 |
whitequark | endmill should have a flat end, right? | 10:09 |
wpwrak | depends. most do, but it can have almost any shape | 10:09 |
whitequark | well I mean, if it's conical, then it is certainly not an endmill, right? | 10:09 |
wpwrak | it could still be an endmill. a conical one :) | 10:10 |
whitequark | hm | 10:10 |
whitequark | what is a difference between a conical endmill and a drill then? | 10:10 |
wpwrak | but you probably know for sure that any drill will be conical :) | 10:10 |
wpwrak | not sure how exactly they differ if they have similar shapes. the endmill cuts anywhere along the thread but maybe drills do, too | 10:11 |
whitequark | I'm faaaairly certain that it does have a conical end | 10:11 |
wpwrak | endmills are designed for lateral loads while drills aren't. so they're shorter and usually harder | 10:12 |
whitequark | my eyes don't quite have enough resolution to figure this out, even with a loupe | 10:12 |
whitequark | lemme take a picture | 10:12 |
wpwrak | at some size it gets hard to see the difference | 10:13 |
wpwrak | but anyway, they'e far too long to be normal endmills | 10:13 |
wpwrak | typical diameter to height ratio at small sizes is in the order of 1:2 | 10:13 |
wpwrak | well, maybe a bit more. 1:4 seems more typical | 10:16 |
wpwrak | though some make them shorter | 10:16 |
wpwrak | below 1 mm, it gets closer to 1:3 | 10:17 |
wpwrak | e.g., i see in a shop one for 0.3 mm -> 1 mm | 10:17 |
whitequark | http://i.imgur.com/NLqHPiP.jpg | 10:18 |
whitequark | grr, not good enough | 10:19 |
whitequark | I'm at rigidity limit of my tripod... | 10:19 |
wpwrak | above diameters of about 2-3 mm, the length can considerably increase. seems that you're at a point there where the softer materials are hardly a burden anymore | 10:19 |
wpwrak | e.g., that same shop has one with 3 mm -> 52 mm | 10:19 |
wpwrak | looks like a drill :) | 10:20 |
wpwrak | try moving it sideways at 0.5 mm/s or slower, see if it still dances around | 10:21 |
wpwrak | btw, you're lucky that it's HSS. if it was tungsten, you'd have chopped it right off at 10 mm/s | 10:21 |
whitequark | http://i.imgur.com/j2Fx3oK.jpg | 10:28 |
whitequark | can't get a better pic | 10:29 |
whitequark | tbh I'm not sure I even understand what is it at the end | 10:29 |
whitequark | or in fact I can | 10:31 |
whitequark | wpwrak: http://i.imgur.com/dHJPuPO.jpg | 10:32 |
whitequark | another endmill/drill(?) though | 10:32 |
wpwrak | looks like a drill | 10:34 |
wpwrak | maybe the cn->en dictionary has drill -> bit (they're synonymous after all) and the cn->en dictionary has bit -> endmill | 10:36 |
whitequark | with less chromatic aberration: http://i.imgur.com/d2Rqemx.jpg | 10:36 |
whitequark | definitely does look like a drill | 10:36 |
whitequark | okay, time for more angry amazon reviews | 10:37 |
wpwrak | good picture. and yes, it's till a drill :) | 10:37 |
wpwrak | #s/till/still/ | 10:37 |
whitequark | (picture) yeah, this camera's pretty amazing. quite a good microscope in fact! | 10:38 |
whitequark | http://www.amazon.com/gp/product/B008RE2VJ4/ref=oh_details_o07_s00_i02?ie=UTF8&psc=1 | 10:39 |
whitequark | hahaha lolwhat, it says "carbide" in description but "tungsten steel" below | 10:40 |
wpwrak | dilithium-plastic :) | 10:41 |
DocScrutinizer05 | usual, tungsten steel with tungsten carbide finish or cutting stones | 10:43 |
wpwrak | but according to the amazon reviews, someone got it to work for pcbs. of course, running very slowly, but that's already clear from the shape | 10:43 |
DocScrutinizer05 | oops nope, they say tungsten steel BLADE | 10:46 |
whitequark | hahaha | 10:57 |
whitequark | I bought two sets of endmills from different amazon vendors | 10:58 |
whitequark | now I look at them and there's exactly same handwriting on labels | 10:58 |
whitequark | ccccccdcecigibilitjigvbthegidhvdlflfhfubnuvf | 11:09 |
whitequark | er | 11:09 |
larsc | bless you! | 11:21 |
Action: whitequark giggles | 11:22 | |
whitequark | I accidentally triggered yubikey, if you're curious | 11:25 |
whitequark | wpwrak: so I finally got some plywood for victim material | 11:33 |
whitequark | idea: mill out a grid of depressions on the bottom side. place nuts inside. wait for squirrels to appear | 11:33 |
whitequark | er, I meant: use bolts to quickly move fixture on the top side without unscrewing the sheet completely | 11:34 |
whitequark | 6mm plywood... not very much headroom but should work | 11:34 |
whitequark | say, an M3 nut is 2.4mm thick. mill out a 3mm deep depression. use a 12mm screw. then actually use the remains of my 6mm sheet in this way: | 11:39 |
whitequark | cut out a small rectangular piece. drill hole for screw. mill off material off half the piece where the workpiece will be | 11:40 |
whitequark | what do you think? | 11:40 |
wpwrak | whitequark: for comparison, here's a 12 mil endmill, usable length 18 mil: http://downloads.qi-hardware.com/people/werner/tmp/6mil-9mil.jpg | 12:56 |
wpwrak | and here 12 mil, usable length 18 mil: http://downloads.qi-hardware.com/people/werner/tmp/12mil-18mil.jpg | 12:57 |
wpwrak | (wood) why not just: 1) put wood on mill, 2) put workpiece on top, 3) fix workpiece with clamps, making it push down on wood. i.e., keep things simple :) | 12:59 |
wpwrak | i also made some fancy fixtures (of aluminium, no less) at first but then never used them ... | 12:59 |
CYB3R | Hi all! | 13:37 |
DocScrutinizer05 | dang, Ukraina goes hot | 16:19 |
DocScrutinizer05 | and of course Russia is going "Oh, they gather tanks and weapons behind the frontier. This looks like a serious threat agianst our own troops' ability to move in there. So let's move in there before it is too late" | 16:21 |
DocScrutinizer05 | the Georgia model | 16:22 |
DocScrutinizer05 | :-( | 16:23 |
whitequark | wpwrak: well yes, that is exactly what I want to do | 17:28 |
whitequark | how are you going to attach clamps to wood? | 17:28 |
wpwrak | not to the wood but to the thing on top | 17:38 |
wpwrak | well, unless you have to glue it to the wood. depends on the use | 17:38 |
wpwrak | if you have to glue, maybe take plastic-laminated wood. that would have a smooth surface. and then clamp the wood | 17:40 |
DocScrutinizer05 | glueing the PCB is probably never a really nice idea, unless it's only about drilling holes all way through | 17:46 |
DocScrutinizer05 | Z axis undefined when glueing | 17:46 |
DocScrutinizer05 | not that it would drift, once you glued it, but for sure you can't define beforehand where the PCB will be on Z-axis | 17:47 |
DocScrutinizer05 | which is particularly nasty since generally you want to make sure that PCB is parallel plane to your CNC table and thus the X/Y-plane | 17:48 |
DocScrutinizer05 | maybe your controller sw can cope with non-level non-"horizontal" surface of PCB, then all you need to do is taking values for 3 precise level measurepoints | 17:51 |
wpwrak | glue, raise bit a little, then position the head in the "on pcb" position, release the bit, drop it on the pcb, then tighten again | 18:02 |
wpwrak | (where "glue" = double-sided adhesive tape) | 18:11 |
DocScrutinizer05 | s,X/X,X/Y, | 18:59 |
DocScrutinizer05 | doesn't help | 18:59 |

wpwrak | for a bit of weekend relaxation, i found this nice rogue-like: http://www.zincland.com/7drl/kobold/ | 22:26 |
DocScrutinizer05 | Oh my. what were those called? text adventures? | 22:43 |
wpwrak | rogue-like :) | 22:48 |
wpwrak | it's a pretty funny one. very tongue-in-cheek | 22:48 |
wpwrak | to run it, if the binary doesn't work, you need ... | 22:48 |
wpwrak | http://www.uploadable.ch/file/jDTx4mw39svY/kobold002.patch | 22:50 |
DocScrutinizer05 | I wonder what happened to Elite (recent sequel). I think Braben(?) should have finally finished it. | 22:51 |
wpwrak | and then these instructions: http://pastebin.com/Remq9bei (apply patch after unzipping) | 22:51 |
wpwrak | elite ... that's from before the war, right ? | 22:52 |
wpwrak | i mean the one with napoleon | 22:52 |
DocScrutinizer05 | http://www.theskinny.co.uk/latest/307156-a_new_frontier_behind_scenes_elite_dangerous | 22:52 |
DocScrutinizer05 | http://elite.frontier.co.uk/ | 22:57 |
DocScrutinizer05 | yes, that's from before the KT-impact | 23:15 |
DocScrutinizer05 | I wonder if they eventually will offer "Elite: Dangerous" for linux too | 23:26 |
DocScrutinizer05 | I mean, when they can offer for osx | 23:26 |
DocScrutinizer05 | ((age)) this should answer it ;-) >>Elite © 1984 David Braben & Ian Bell. Frontier © 1993 David Braben, Frontier: First Encounters © 1995 David Braben and Elite: Dangerous © 2012, 2013 Frontier Developments plc.<< | 23:32 |
DocScrutinizer05 | I first played Elite on a Schneider CPC64 | 23:35 |
