18:30 home hey guys
18:30 home whats up
18:30 home so batteries
18:30 ace4016 suck
18:30 home where can I find me some?
18:30 ace4016 one sec
18:30 Tom_itx at the battery store
18:31 home how?
18:31 ace4016 they are tons online
18:31 ace4016 and many locally depending on where you live
18:32 home I got some old lappy batteries lying around
18:32 home think they have any hope?
18:32 ace4016 maybe
18:32 home really :o
18:33 ace4016 old school laptop batteries may not be lithium based, which means they might survive the test of time :p
18:33 ace4016 just have to do the proper recovery procedures depending on battery recovery
18:33 Centauri home: what *kind* of batteries? what current requirements?
18:33 ace4016 battery type*
18:44 home Centauri: 12v-9v
18:44 home ace4016: hmm, 2001 laptops :/
18:44 home lappy battery
18:45 home is there hope?
18:45 ace4016 depends, i think some still used nicd/nimh
18:46 ace4016 what type are they?
18:54 home lemme check
18:58 home good damn it
18:58 home I dont think this lappy has a battery
18:58 home but found me a heatsink :D and fan :D
18:59 ace4016 lol
18:59 home its useless..
19:00 home now, if I can find a fan that can do PWM, and has a tacho, that could be useful :D
19:03 home wow, the cpu paste is still coool...
19:16 home well, I stole the heatsink
19:16 home but I think the thing has a built in battery somewhere
19:16 home for an old laptop, this thing was clean as hell...and no dust
19:17 DagoRed cool
19:19 home but meh
19:19 home what else can I yank out that is usable?
19:19 home got a 6GB hd :D
19:19 DagoRed oh that is an old laptop.
19:19 DagoRed Honestly, if you can grab any voltage regulators those would be awesome.
19:19 home yeah
19:19 DagoRed Those old laptops had some beefy ones.
19:25 home but where?
19:25 home how do they look like XD
19:26 DagoRed Oh... they look like big transistors.
19:26 DagoRed They have metal backs for pulling the heat away.
19:26 home yeah, those, now I remember
19:26 home used to convert ac voltage to dc right?
19:26 DagoRed no
19:27 home hmm
19:27 DagoRed They convert higher dc voltages to lower dc voltags.
19:27 DagoRed *voltages
19:28 home I found the battery
19:28 home BAttery, Lion 9 cell
19:28 home is that any good?
19:37 DagoRed if it's an old laptop... the cells might be bad
19:39 home yeah :/
19:39 home sigh
19:39 home but some cells might be good right? :D
19:40 DagoRed maybe
19:40 DagoRed I don't know how to check them without a battery charger that is rather expensive made for RC applications.
19:57 home lol
20:32 home Anyone here is expierenced in building boards with multiple FPGA implemenetations, with expierence in Pin assignments, etc. and Signal integrity for DSP processing?
20:35 ace4016 sorta; had a specific question?
20:39 home ace4016: meh, someone was looking for a PCB designer or something
20:40 static ki-cad
20:42 ace4016 home, was his name Jentrep?
20:42 home yes..
20:42 home lol
20:42 ace4016 yea, he asked in ##electronics but was a doucehbag and never asked his actual question
20:43 DagoRed lol
20:44 home LOOL
20:44 DagoRed http://en.wikipedia.org/wiki/IP_over_Avian_Carriers
20:48 home DagoRed: that is a very interesting read, and just opened up my mind, especialyl since I took care of a pidgeon a while ago... 0_0
20:48 Centauri lol
20:49 ntauri peeks inside the opened
21:14 rue_mohr heh, you just heard about that one eh?
21:16 rue_mohr oh I wanted to try to turn a camera into a microscope
21:19 home rue_mohr: I am interrested, please go on :d
21:19 home rue_mohr: That would be an awesome project to do :D
21:19 orlok "camera".. webcam? or real still camera?
21:19 rue_mohr camera <- lenses = microscope!
21:20 orlok you can flip around a zoom lense and it acts as a macro
21:20 orlok i think theres even adaptors to do it
21:20 rue_mohr I wanna see about 400x
21:21 orlok realtime, webcam style?
21:22 orlok i'd say spend what you want on the webcam, or re-use a spare, and find the best quality second hand microscope you can
21:22 orlok or, you can buy them ready made :)
21:22 rue_mohr I have a real videocamera I can use
21:24 home rue_mohr: I dont :/
21:32 Tom_itx https://plus.google.com/photos/103607741810677023482/albums/5698695539719986129
21:37 home Tom_itx: seems very time consuming :/
21:37 Tom_itx you'd rather sit here and idle?
21:38 Tom_itx it was one i ran across
21:45 home Tom_itx: Not every one of us have the tools and the knowledge to necessary accompany them..
21:56 Tom_itx we can learn though
21:56 Tom_itx and acquire things along the way
22:05 Centauri ;)
22:13 home Tom_itx: yeah, you can :/
22:13 home I still need mah tools
22:13 home no oscilloscopes or anything..
22:14 Tom_itx you can do without one
22:15 home yeah
22:15 home was an example, but meh
22:16 home December is going to be hell for me..
22:16 home I have no routine..
22:16 home 2013 is looking horrible
22:46 Centauri home: can you see into the future?
22:58 home Centauri: Yes
22:58 Centauri heh
23:00 Centauri home: that would truely depend on which of the 10^500 uiverses you are a part of.. since according to QM,, all possibilities are exercised in some version of the universe ;)
23:02 Centauri AKA "Quantum Leap" and "Sliders" were not so far off after all ;)
23:07 home I can share my thoughts and experiences with all the other me's in all the other universes
23:08 home and thus have garnered a prophetic view of this world..
23:08 home I can tell you the outcomes of an event, based on the mere probability of it already having occured, in these other universes.
23:09 Centauri Well, given that all outcomes play out in some alternate universe, you are predicting exactly nothing, because EVERY possible occurance, has happened
23:35 rue_shop3 Tom_itx, haha
23:36 rue_shop3 I need a 12V voltage inverter to get the rs232 to work on buddyIII
23:36 rue_shop3 who said soemthing about a 555 cand caps and diodes
23:38 rue_shop3 !time
23:38 tobbor My watch says its 09:26PM Mon Nov 26 2012
