#emc-devel | Logs for 2008-05-29

[02:59:10] <dmwaters> {global notice} Good day all, one of our European hubs had a major routing problem but things look to be alright now, thank you for your patience, and thank you for using freenode!
[14:53:07] <kloeri> [Global Notice] Hi all. At 1600UTC today (a little more than an hour from now) freenode migrates to a new services package. Services will be gone for a few minutes during the migration but it shouldn't take too long. Thank you for using freenode!
[15:42:40] <skunkworks> I am a little worried about the amount of time jepler seems to be spending on console gaming. Do we need to have an intervention at the workshop?
[15:43:36] <SWPadnos> no. I think anyone who owns a console should be required to bring it
[15:44:08] <SWPadnos> err - so we can - um, port EMC2 to it
[15:44:25] <skunkworks> ps3 supposidly will run linux.
[15:44:40] <SWPadnos> yep - it's even supported by Sony
[15:44:47] <skunkworks> I think there was an issue though with the video card being closed..
[15:44:52] <skunkworks> (last I looked)
[15:45:12] <SWPadnos> I don't think that's the problem. they locked out one of the special function processors IIRC
[15:45:45] <SWPadnos> so you only get access to the PPC master and 7 of the 8 Cell processors
[15:56:26] <christel> [Global Notice] Hi all! As you are aware services will shortly be going down for a move to the new services package, all *Serv will be DOWN for a few minutes while we migrate the DB. For once I encourage you to op yourself in your channels to deal with any potential problems during the downtime. Thanks.
[16:00:41] <jepler> http://en.wikipedia.org/wiki/Linux_for_PlayStation_3#RSX_Homebrew -- sony blocked access to some part of the GPU (texture related?) after open source people found a way to use it.
[16:00:45] <jepler> I don't have a ps3 though
[16:00:53] <jepler> and I don't know who told you I spend all my time playing console games
[16:01:03] <SWPadnos> skunkworks did it :)
[16:02:39] <SWPadnos> ah ok - that's what I was (mis) thinking of - I thought it was a specific part of the CPU rather than the GPU
[16:03:03] <SWPadnos> I'm considering getting a PS3 since they're one of the better BLuRay players available
[16:04:44] <jepler> I'll hold out for a blueray player on linux, since I have no plans to buy a high-def tv.
[16:05:09] <SWPadnos> I think Linux can play bluray discs already, but I'm not sure about hi-def
[16:13:55] <skunkworks> jepler: I extrapolated from your blog. :)
[16:15:16] <jepler> ah I guess I did say "devouring my time" :-P
[16:15:44] <skunkworks> I actually played a wii for the first time this weekend. Ski and baseball.
[16:16:12] <jepler> there are some fun games and lots of really terrible ones
[16:16:17] <jepler> is ski one of the new "wii fit" games?
[16:16:54] <skunkworks> is it call skiball?
[16:17:04] <jepler> I dunno
[16:17:06] <skunkworks> * skunkworks is not up on them.
[16:17:10] <skunkworks> fun though
[16:17:20] <jepler> is it one where you stand on the board thing?
[16:17:26] <skunkworks> no
[16:17:30] <jepler> ok then
[16:18:06] <jepler> that's the newest gimmick for wii, the "balance board"
[16:23:06] <skunkworks> heh - looks like it could be fun for some things.
[16:24:12] <skunkworks> it is my sisters wii.. SO far - (5 people all togather) like dodge ball
[16:24:48] <jepler> I haven't really gotten into the group game thing much
[16:25:37] <jepler> some of my recent favorites have been: zelda, okami (both adventure games) and geometry wars (old style 2d/vector arcade shooter)
[16:27:24] <jepler> I'd be happy to bring it to fest but I don't think there are any TVs to plug it into
[16:28:16] <skunkworks> someone would have to bring a nice flat pannel to mount on the wall. :)
[16:28:49] <jepler> or put a bluetooth dongle on the mazak and set it up so that you wave your arm around to jog the machine
[16:29:14] <SWPadnos> "here, catch"
[16:29:26] <SWPadnos> NOT!
[16:29:48] <skunkworks> osha would not approve
[16:30:00] <jepler> we won't invite them
[16:30:28] <SWPadnos> yeah. it's not osha, it's more like "oshit"
[16:51:24] <christel> [Global Notice] Hi all! Our Services migration is taking slightly longer due to unexpected complications, I apologise for the interruptions. Until the move is complete further information will be given as wallops, to read these please /umode +w yournick. Thank you!
[17:33:48] <christel> [Global Notice] Aaaaand we make contact! A small step for manki..oh wai-! Sorry about the delay there and thank you for your patience. Services are now back up!
[17:39:28] <christel> [Global Notice] Hi again (sorry for the spam!) -- Many of you are experiencing being kicked from +i channels despite having a invex set (+I) -- this is a isolated occurance relating to the move and should not happen again. Please direct any further questions to #freenode. Thank you
[18:52:43] <SWPadnos> any snack food requests for the workshop?
[18:52:47] <SWPadnos> (pro or con :) )
[18:53:12] <alex_joni> that's bad for your health :P
[18:54:06] <SWPadnos> I disagree. I think food is good for my health
[18:54:32] <alex_joni> not snacks\
[18:54:51] <SWPadnos> heh
[18:55:12] <alex_joni> maybe fruits :)
[18:55:12] <SWPadnos> those are good for my mental health
[18:57:21] <alex_joni> well.. then I trust your judgement :)
[19:10:03] <jepler> SWPadnos: yes, I request that you bring a whole mess of snack food to fest; so much that we can't possibly eat it al
[19:10:07] <jepler> l
[19:11:27] <SWPadnos> do I hear a second?
[19:14:46] <BigJohnT_> http://www.youtube.com/watch?v=3xZ3QTHaink
[19:39:49] <christel> [Global Notice] Hi Again! It's your favourite spammer.. We're going to have to restart Services and run the conversion again, thanks to those of you who found bugs and pointed out issues! This restart should be a lot quicker than the last.
[19:42:10] <cradek> BigJohnT_: cool. I have a wireless renishaw like that but no receiver for it!
[19:46:48] <BigJohnT_> cradek: hot wire it!
[19:47:22] <cradek> I have not tried to open it up, and it has no external connectors. I could probably make the receiver but I can't find any information (unsurprisingly)...
[19:47:46] <SWPadnos> do you have batteries for it?
[19:47:55] <SWPadnos> (or does it use some ingenious generator scheme)
[19:47:56] <cradek> it's just a 9v
[19:47:58] <SWPadnos> ok
[19:48:23] <SWPadnos> if you want to, I may be able to take it into the RF lab at my old business
[19:48:29] <SWPadnos> want me to
[19:48:31] <cradek> I have to assume it communicates "are you there?" "yep" "are you there?" "yep" but I haven't figured out how to verify this
[19:48:40] <cradek> I'm pretty sure it's IR!
[19:48:48] <SWPadnos> oh, that's a lot easier :)
[19:49:02] <SWPadnos> if it is, we can get a sensor and look at it on a scope
[19:49:11] <cradek> hmm it sure could be xmit only
[19:49:18] <cradek> "I'm here" "I'm here" "I'm here" "I touched something"
[19:49:31] <cradek> no, how would it know when to turn on? hmmmm
[19:49:42] <SWPadnos> it's got to transmit based on touch only
[19:49:44] <cradek> can you tell I haven't worked on it much yet?
[19:49:49] <SWPadnos> a 9V has almost no energy
[19:49:59] <SWPadnos> does it have an on/off switch?
[19:50:11] <cradek> I don't remember
[19:50:23] <cradek> if it xmits on touch, that's easy :-)
[19:51:01] <SWPadnos> it's a radio
[19:51:05] <cradek> obvious thing to do is rig a receiver assuming it's 40kHz carrier, and see what I get
[19:51:15] <BigJohnT_> I can ask my buddy in the video if he knows, he is pretty good at scrounging up info on stuff
[19:51:43] <cradek> SWPadnos: I'm 99% sure it has IR LEDs sticking out in a circle
[19:51:51] <cradek> but I haven't looked at it for months
[19:52:34] <cradek> http://www.atechauthority.com/pdf/mp700_data.pdf
[19:53:45] <cradek> BigJohnT_: wonder if he has any leads on a receiver module... I think the probes break all the time and then get retired because they're so amazingly expensive
[19:55:41] <cradek> if this is the one I have (and it sure looks like it) it is certainly bidirectional
[19:56:57] <cradek> so "all" I need is a logic analyzer, IR receivers, and someone with a working one, to reverse-engineer the IR code
[20:01:52] <BigJohnT_> cradek: I'll e-mail him and ask
[20:02:09] <cradek> thank you!
[20:03:05] <BigJohnT_> done
[20:04:40] <cradek> thanks. I guess it couldn't hurt to price the (new) parts I need, but I'm afraid it'll be out of my reach
[20:05:47] <SWPadnos> ok - they have both. the OMP series uses optical and the RMP series uses radio
[20:07:14] <SWPadnos> if you have the radio one, you're lost. it uses frequency hopping spread spectrum
[20:07:27] <cradek> I know mine's IR
[20:07:32] <SWPadnos> that's good then :)
[20:08:33] <SWPadnos> you sure it uses a 9V?
[20:09:05] <cradek> yes
[20:10:02] <cradek> "alkaline duracell MN 1604" this datasheet says
[20:10:14] <SWPadnos> http://www.renishaw.com/media/pdf/en/b8801a84448749498c0b826e8cf1a0d4.pdf
[20:12:48] <cradek> cool, part numbers
[20:13:02] <cradek> I'll look again and see if I actually have MP700
[20:13:38] <cradek> can't use it yet... but after emc conversion!
[20:14:45] <SWPadnos> if you do have the MP700, there may be more information here: http://www.renishaw.com/en/6104.aspx
[20:16:37] <cradek> ack, they don't have the right shank either
[20:17:16] <cradek> oh maybe BT 1982
[20:20:18] <SWPadnos> Big Taper for 1982 Mill ?
[20:20:51] <cradek> nope NMTB != BT
[20:21:38] <cradek> there are a lot of obstacles to my using this probe :-)
