BhaalErm...  Isn't AU in bed with the US just as much as the UK is?09:17
aholleryes, but isn't au part of the uk? ;)09:20
tbrI think you are thinking commonwealth09:22
aholleris there a difference? ;)09:22
ahollerjust kidding ;)09:24
aholleri've no idea who is a terrorist in the eyes of the five eyes and needs to fill out forms09:25
Bhaalhahaha09:26
BhaalIsn't the person who was asked to fill one out from the UK though?09:27
BhaalI really am hoping that the fact my max hasn't been sent out isn't because I haven't filled out a form I haven't been sent to fill out...  ie: pre-orders before the whole shipping screw up happened haven't been sent this form when they should have...09:28
Bhaalie: only new orders since then are being filled09:29
ahollermaybe they decide who gets a form presented based on some list of evil individuals09:29
aholler+sekret09:29
Bhaalyay09:29
Bhaalbody slammed in the head by 2 lorikeets09:30
bluelightningwell, unfortunately being in Australia doesn't get you out of this kind of nonsense... http://www.eevblog.com/2014/02/24/element-14-holding-orders-based-on-us-government-watch-list/09:30
BhaalI wonder if that is why we haven't seen that asrock atom board with 12 sata connectors on it yet?09:31
bluelightningI remember ordering some accelerometers in NZ from Analogue Devices, I had to sign something saying I wouldn't be using them to make missiles or send them to a list of "undesirable" countries09:31
BhaalHmmm...09:32
BhaalStarting to think its time to contact Mouser and find out what the go is...09:32
aholleromg, and I though what I've just said is sarcasm09:32
BhaalUnless prpplauge or warthog9 can shed some light on the situation09:32
Bhaalaholler: You didn't think poeople in au/nz would need to sign these things?09:33
ahollerI didn't think that orders will be handled based on lists of individuals09:34
aholler(sekret lists)09:34
BhaalThey probably are... *shrug* I just want to know whats going on09:34
tbrBhaal: sounds more like internal distribution slowness of mouser. especialy if you go by the recent mail of someone base also in the UK09:34
Bhaaltbr: Yeah, saw that, but also that could be a right hand/left hand thing as well09:35
BhaalSome staff know, some don't know09:35
Bhaalhence wrong information is going out...09:35
Bhaalwhen people are calling09:35
ahollerbut as so often, the world has become much more crazy that one could believe09:35
Bhaalindeed09:36
ahollerbluelightning: really an unbelievable story you've posted. crazyness at it's best.09:46
bluelightningaholler: indeed09:47
BhaalThe e14 story?09:47
bluelightningat the very least the element14 folks told him about it; they could have just clammed up09:48
bluelightningall seems a bit silly though09:48
BhaalI don't think there is anything specific to hide behind09:49
Bhaalie: if your NAME is a NAME of interest then *shrug* who cares...  sign the form and move on...09:50
BhaalI am happy to sign a form..  if that is why my Max hasn't been sent :)09:50
ahollermost people don't like to be an official evil for the US09:51
BhaalI don't have enough f's to give with regard to something like that..  They can come pay me a visit at home if they need to, I know they won't find anything here..09:52
BhaalUmmm..  and there is no emphasis placed on the word "here"09:52
Bhaal>.>09:52
Bhaal<.<09:52
BhaalSo I guess "David Rolfe" is a name on that US register :)09:56
BhaalI guess I am not evil enough09:56
BhaalThat could change though, depending on how long it takes Mouser to ship :)09:57

RzRI can adapt this for max : http://www.reddit.com/r/Tizen/comments/2dm1nx/use_xbmc_on_tizen_until_tizen_tv_are_on_sale/11:34
Inge-just curious for your thoughts on the two. I'm pretty sure the minnowboard follows what one could expect for that cpu / ram combo11:41
BhaalSooooo... what did I miss while I was busy fixing the raid array in my server after a drive lost power11:53
BhaalInge-: If you are looking at those too, then it comes down to requirements like: Do you need it in a pretty case? (that will happen for the max down the track)  Do you want all your connectors on 1 edge of the board?  Do you need more then a regular PC, ie: do you need to control other things or want specialised stuff like mpcie or msata?  Does it matter that you cannot expand the amount of memory for the machine?11:56

prpplaguecarpman: doing a lure to interface to that should be simple enough17:10
*** bluelightning <bluelightning!~paul@pdpc/supporter/professional/bluelightning> has quit IRC17:33
carpmanprpplague: use their motor driver I assume?17:37
carpmanjust drive it from the pc interface17:37
prpplaguecarpman: yea just drive it from the pc interface17:37
prpplaguecarpman: just need 9 gpios17:37
prpplaguecarpman: +5v17:37
carpmanno, we must do full parallel ;) Get me an FPGA!17:38
prpplaguehehe17:38
carpmanyeah, simple enough, its the software interface from linuxcnc that will be tricky17:38
prpplaguecarpman: think so?17:38
prpplaguecarpman: i thought there was an interface already for eagle17:39
carpmanprpplague: maybe, I'm just unsure because I've never interfaced any new hardware to linuxcnc17:39
prpplaguecarpman: hmm17:39
carpmanprpplague: thats to get board files into gcode, different kind of interface17:39
prpplaguecarpman: i had not even looked at using linuxcnc17:39
prpplaguecarpman: right there was a g-code interface for this thing17:40
prpplaguecarpman: guess i need to do some more research17:40
carpmanprpplague: you need something like it, to take gcode commands and set the GPIOs accordingly17:40
carpmanhehe, welcome to CNC land17:40
prpplaguecarpman: yea i was reading a bunch of folks just had a g-code interpreter17:40
prpplaguecarpman: goal would be to do a pcb in eagle, and just "dump" to the cnc17:41
carpmanprpplague: thats what linuxcnc is, but the interpreter has to understand a little of the hardware. I've seen it interface to these kind of parallel drive setups before on PCs, might not be too difficult to interface via GPIOs17:41
prpplaguecarpman: i'd guess if there is a parallel port setup for linuxcnc then having it for GPIOs should be difficult17:42
prpplaguecarpman: but i thought linuxcnc was all gui based and such17:42
carpmanprpplague: it is, you need that to move the head and zero out before a run17:43
prpplaguehmm17:43
carpmantools might be of different lengths, so you have to move the head around and then home it so it knows where the origin is in 3d space17:44
prpplaguecarpman: there a sub $100 unit out there that we could use as a test bed?17:44
carpmanprpplague: the DMS has one of these kind of CNC mills, with a parallel interface. We could hook our hardware up to it for testing17:45
prpplaguecarpman: yea, i was looking for something for myself to learn on17:46
carpmannothing quite that cheap, unfortunately17:47
seaLnelooks like that is mouser shipping out some more maxs17:47
prpplagueseaLne: yea we've been doing pretty consistent shipments to them17:48
prpplaguecarpman: aren't there some mini 3d printers?17:48
seaLnefor a max ordered on 27th june17:48
carpmanprpplague: the printrbot simple is the best of those. $349.17:50
carpmanfor the wooden one17:50
prpplaguecarpman: hmm17:51
prpplaguecarpman: i swear i had seen a mini 3d printer for less than $10017:52
prpplaguecarpman: but then i am old17:52
carpmanprpplague: you might be thinking of the peachy, it exists but is as yet unreleased17:53
carpmanits an SLA, SLAs are hard to get right17:53
prpplaguecarpman: i was less thinking of actually doing 3d printing17:53
prpplaguecarpman: just wanted to play with the x/y/z17:53
carpmanyeah, I just brought it up because its the right price.17:54
seaLneone of the really annoying things about the mouser shipping emails is that they only tell you there is a shipping reference number in the html version, not in the plain text part17:54
carpmanprpplague: you could borrow my printrbot simple if you wanted. It needs a little TLC, I've borroed a couple of parts off of it for another printer ;)17:54
carpmanall the platform hardware is there, just the nozzle part I've taken off17:55
prpplaguecarpman: yea, i'd not want to tear up your stuff17:55

maxtothemaxso if I apply power to my minnowmax, and the power indicator comes on, but the on/off indicator stays off, and there's nothing on serial or HDMI, and the power button does nothing, and a reflash doesn't fix it, that means the board is dead right?18:03
prpplaguemaxtothemax: yea18:05
maxtothemax:(18:05
prpplaguemaxtothemax: most likely an issue with the PMIC18:05
maxtothemaxpower manegement integrated circuit, according to google18:06
prpplaguemaxtothemax: yes18:06
maxtothemaxthat's like those voltage regulator transistors right?18:06
prpplaguemaxtothemax: simplified, but yes18:06
prpplaguemaxtothemax: any idea about what was being done to the board before it stopped working?18:07
maxtothemaxno18:07

maxtothemaxnext day it's dead18:07
maxtothemaxhowever it had its power adapter plugged in all night18:07
maxtothemaxand I didn't have it in a case18:07
maxtothemaxso maybe it brushed up against  something metal and shorted out?18:07

prpplaguehehe yes please do send it back to me18:10
* maxtothemax maps nick to name18:10
maxtothemaxunfortunately I didn't think to rip the firmware before I reflashed, so you won't be able to look for deadly settings18:13
prpplaguemaxtothemax: i doubt it is firmware related18:19
maxtothemaxI have heard that bad settings can release the blue smoke18:19
prpplaguemaxtothemax: i suspect that the pmic might have had a bad solder joint and after leaving it running all night that the head expanded the connections enough to not make a connection18:19
maxtothemaxalthough I think all I did was change LPSS enumeration to ACPI18:19

maxtothemaxthat makes sense18:20
prpplaguecarpman: http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Robotics/EasyDriver_v44.pdf18:20
carpmanyep, three of those and a relay for the spindle18:22
carpmanand some hardware to read limit switches18:22
prpplaguecarpman: have you used one of those before?18:23
carpmanprpplague: not that one specifically, but its the same circuit on almost every 3d printer/CNC board18:24
carpmanthe problem comes down to reading the limit switches, and controlling the stepper drives in close to real time with linux. Thats why the BB capes for this use the PRU18:25
carpmanlast thing you want to have happen is an interrupt right when the limit switch closes :)18:26
prpplaguecarpman: hmm18:27
carpmanfor destructive processes though, interrupts during a cut are fine, if theres a tiny pause nothing gets ruined18:27
carpmanprinting, OTOH, it causes huge issues, since you are melting plastic if you sit too long18:27
prpplaguecarpman: ahh right18:27
prpplaguecarpman: but from what i was reading, doesn't the A3967 handle the stepper control from a single step pulse?18:28
prpplaguecarpman: the gpio doesn't need to toggle the step pulse with specific timings, right?18:28
carpmanprpplague: right18:29
carpmanprpplague: most boards nowdays use that family of driver, see http://smoothieware.org/smoothieboard18:30
prpplaguecarpman: do we have any steppers hanging around over there?18:30
carpmanone I think, and tanners has some nice ones for about $518:30
prpplaguehmm18:30
prpplaguecarpman: i didn't even think about tanners18:31
