#emc | Logs for 2007-07-15

[00:03:47] <tomp> I had to increase the Cache-Limit , update, get the pkg, remove the huge repository from list, reduce the cache, re-update (phew! all for a little java app )
[04:48:36] <tomp> join #FreeMind
[04:49:10] <chr0n1c> ahh i just discovered how to make the irc window transparent.. yay
[04:49:38] <chr0n1c> now i can see my coolio wallpaper
[04:51:44] <chr0n1c> hey i guess i am emailing that person in cali from the mailing list a cd... my good deed for the week.
[04:52:08] <chr0n1c> soo you folks might be helping him out a lot soon...
[04:52:23] <chr0n1c> fun stuff.. i know, try to contain the excitement!
[04:57:29] <cradek> thanks for sending him a disc
[04:58:08] <chr0n1c> no prob... i figure it's a way for me to contribute...
[04:58:32] <chr0n1c> you guys have done some awesome work... i'd like to help people find it
[04:59:03] <cradek> thank you
[04:59:09] <chr0n1c> ;)
[04:59:35] <cradek> it's unusual that someone can't get a disc made locally somehow, but it's impossible to guess what his situation is
[05:00:15] <cradek> were you one of the guys who wanted to work with hot wire cutting?
[05:00:30] <cradek> fosm
[05:00:32] <cradek> foam
[05:01:16] <chr0n1c> me? no, it is a topic i would like to learn more about though in the future
[05:02:22] <Jymmm> cradek: I was, but no immediate need
[05:03:07] <Jymmm> cradek: not a top priority I mean.
[05:03:17] <chr0n1c> i just peeked in on the on-disk.com website. it looks like they are a reasonably priced serrvice
[05:03:43] <chr0n1c> $3.99 per disc with no label, as long as they don't have to do much work
[05:04:00] <cradek> yeah it seems like a nice service
[05:05:11] <chr0n1c> have you given thought to asking them to list emc2/ubuntu on the site as a possible burn-able disk image?
[05:06:30] <cradek> that is an interesting idea
[05:06:48] <chr0n1c> cradek: http://on-disk.com/index.php/cPath/28_80
[05:06:52] <chr0n1c> live distros
[05:06:54] <chr0n1c> **
[05:09:49] <cradek> I bet they would list any distro after getting a few requests for it
[05:09:59] <cradek> seems like that would be the smart way to decide what to list
[05:10:56] <chr0n1c> i've been tempted to start something like that service for a long time...
[05:11:14] <chr0n1c> i even made a budget up for the company including buying a mass duplicator
[05:11:22] <chr0n1c> but.. i never did it
[05:11:24] <chr0n1c> :)
[05:13:17] <cradek> sure seems easy to start. as your needs go up, buy better equipment
[05:13:31] <chr0n1c> http://on-disk.com/portal/index.php?wiki=Getting_Started <-- possible signup page
[05:14:12] <chr0n1c> ** i would suggest adding $1 to the cost of the actual service to donate to emc2 ;)
[05:14:20] <chr0n1c> or even $0.50
[05:14:40] <chr0n1c> (i haven't read the signup so i don't know how that would work)
[05:14:41] <cradek> we're not at all set up for donations like that
[05:14:47] <chr0n1c> ohh..
[05:15:05] <chr0n1c> i read somewhere there was a corp of some sort?
[05:15:11] <chr0n1c> for emc2
[05:15:26] <chr0n1c> i thought*
[05:16:48] <cradek> an elected board, no corporation
[05:17:43] <chr0n1c> i see...
[05:21:33] <cradek> goodnight!
[05:21:44] <chr0n1c> later yo
[05:21:51] <Jymmm> cradek: were you thinking of foam module?
[05:22:27] <cradek> I added support for more linear axes U,V,W
[05:22:45] <cradek> just wondered if anyone was waiting for that specifically
[05:22:49] <Jymmm> cradek: ah, and temperature control?
[05:23:08] <cradek> has nothing to do with temperature control...
[05:23:24] <chr0n1c> hey speaking of that....
[05:23:39] <Jymmm> cradek: Ok, I'll chat with you later on the details of the UVW
[05:24:40] <chr0n1c> i was wanting to build a lexan bender/heat bar. i can basically just attach ac to either end of a long spring and stretch it on a insulating material right? then set that under my lexan whre i want it to bend...
[05:25:15] <Jymmm> chr0n1c: I wouldn't
[05:25:40] <Jymmm> chr0n1c: NiChrome
[05:25:53] <Jymmm> and a transformer for isolation
[05:25:59] <cradek> chr0n1c: the ones I've seen have something that looks like the heating element from an oven
[05:26:16] <chr0n1c> ok well i got the idea from this potpouri pot that broke... it's merely a spring around a ceramic disc with ac and an led in series
[05:26:17] <Jymmm> Yes, that is coiled NiChrome wire
[05:26:19] <cradek> (I've used the oven to do it)
[05:26:29] <Jymmm> It is NOT a spring
[05:26:49] <chr0n1c> oven is a great idea
[05:27:05] <chr0n1c> i know when i try to heat it with my torch to bend it bubbles
[05:27:27] <chr0n1c> but i used a bar once that was tubing with the heater assembly inside
[05:27:30] <cradek> yeah and you can't get a straight line
[05:27:32] <Jymmm> You need good temerature control
[05:27:39] <cradek> oven works ok in a pinch
[05:27:45] <chr0n1c> then you laid your lexan on top of the bar and waited
[05:28:07] <Jymmm> There are specific strip heaters for fabricting plastics.
[05:28:24] <chr0n1c> ... today i tried the potpourii heater, it gets.. ALMOST hot enough
[05:29:25] <chr0n1c> man how do you spell that word...
[05:29:31] <chr0n1c> i know i spelled it wrong
[05:29:37] <chr0n1c> * chr0n1c whips out the dictionary
[05:36:48] <Jymmm> chr0n1c: hey
[05:36:51] <Jymmm> chr0n1c: http://www.cyro.com/Internet/SiteContent.nsf/WebMSDSs/13B65728B6B199CB85256D4A0070CFEF/$File/1319+10E+Thermoforming+TB.pdf?OpenElement
[05:38:27] <chr0n1c> hey that's a pretty nice file
[05:38:35] <chr0n1c> thanks
[05:39:14] <Jymmm> chr0n1c: But THIS is what you were specifically after... http://www.cyro.com/Internet/SiteContent.nsf/WebMSDSs/415A8F19C38ED67285256ADF00496EA8/$File/1319-7F+line+bending+TB.pdf?OpenElement
[05:42:24] <chr0n1c> hey they used my idea in that pdf
[05:43:07] <chr0n1c> i suggested we mill a groove at the bend of some of our machine guards that we were making to prevent bulging...
[05:43:14] <chr0n1c> and it's in that pdf
[05:43:18] <chr0n1c> ...insteresting
[05:43:26] <Jymmm> that pdf is (c) 2001
[05:44:01] <chr0n1c> it was around then when i came up with that idea
[05:44:10] <Jymmm> cough*BULLSHIT*cough
[05:44:20] <chr0n1c> lol, i'm not saying they stole my idea or anything
[05:44:35] <chr0n1c> but i am saying.. "great minds think alike"
[05:44:41] <Jymmm> cough*BULLSHIT*cough
[05:44:50] <Jymmm> ;)
[05:45:29] <Jymmm> I do a lot of plastic fab, but I don't have enough area to do it on a regular basis.
[05:45:29] <chr0n1c> so anyways... we were using a heating bar to bend up some guards for a press we built...
[05:45:44] <Jymmm> 1 car garage
[05:46:43] <chr0n1c> i'm gonna build me a heated plastic bending brake i think
[05:47:40] <chr0n1c> hmm one of the materials for building the bender is in dayton ohio from that last pdf link
[05:47:46] <chr0n1c> right next door almost
[05:47:51] <Jymmm> I have a commercisl strip heater at home, if you wait a few (years) I'll scan it on
[05:47:54] <chr0n1c> wonder if they are still around
[05:53:27] <chr0n1c> thanks, jymmm
[06:39:02] <Jymmm> chr0n1c: np
[07:18:24] <Jymmm> When you have to fit a square part into a square hole, is there a formula for overlapping the cutter's radius so you cna fit the part?
[07:29:50] <chr0n1c> the formula is: subtract .0005
[07:30:11] <chr0n1c> *from the i.d.
[07:36:53] <Jymmm> ?
[07:36:56] <Jymmm> subtract?
[07:37:08] <Jymmm> I'm talking mickey mouse ears here.
[07:40:34] <Jymmm> Let's say the square piece to insert is 1.90". So I have to make a 2" square, and if I'm using a 1/8" diameter cutter, the radius in the corners of the square will be, 1/8". Now, I have to "square" the corners, by (more or less) drilling holes in each of the four corners, but how to I calculate the minimum overlay?
[07:46:42] <chr0n1c> is this a trick question?
[07:46:48] <chr0n1c> jsut use a saw
[07:46:51] <chr0n1c> just*
[07:46:58] <chr0n1c> or a file
[07:47:14] <chr0n1c> or a laser
[07:48:30] <chr0n1c> i bet there is a formula
[07:48:39] <chr0n1c> * chr0n1c has no clue really
[08:00:02] <Jymmm> chr0n1c: Fine, let me borrow a laser from you.
[08:10:48] <Jymmm> chr0n1c: and a shark too
[09:55:58] <chr0n1c> ...fresh out of sharks here.
[09:56:16] <anonimasu> :)
[09:56:16] <anonimasu> I just woke up
[09:56:16] <anonimasu> and I ended up coding
[09:56:52] <chr0n1c> do you code with caffiene?
[09:57:55] <anonimasu> I havent had any yet.. no
