[00:07:01] <GammaX> thats is very awkward lol
[00:07:34] <GammaX> and nothing like myne. I have a hardinge hc converter over to a cnc, has 2 tables mounted to another table on the mill.
[00:07:53] -!- asdfasd has quit [Ping timeout: 240 seconds]
[00:07:59] <GammaX> If only I could think of a way to start bringin in money with that and my mill...
[00:09:40] <Tom_itx> make stuff and sell it :)
[00:09:53] <GammaX> thats the hard part...
[00:09:58] <GammaX> what do I MAKE?! lol
[00:10:08] <Tom_itx> if i told you then i couldn't do it
[00:10:21] <Tom_itx> what ever happened to danimal?
[00:10:51] <GammaX> Tom_itx what sector do you thinkg, would be best to get into?
[00:11:02] <Tom_itx> no idea
[00:11:09] <Tom_itx> depends on your locale
[00:11:18] <GammaX> denver co!
[00:11:25] <Tom_itx> crack pipes
[00:11:32] <Tom_itx> :)
[00:11:34] <GammaX> this is plausible..
[00:11:53] <Tom_itx> there is more drug traffic from there thru here than you can believe
[00:12:35] -!- Tecan has quit [Remote host closed the connection]
[00:13:01] <GammaX> Well I cant make glass items BUT I can deff make crack spoons
[00:13:12] <Tom_itx> they set up drug checks along the highway for that
[00:13:22] <andypugh> Where was Danimal based? His web site still looks live: http://www.homebrewedcomponents.com/store.php
[00:13:31] <Tom_itx> andy, californ i a
[00:13:49] <Tom_itx> he was so active for a while then just dissappeared
[00:14:00] <Tom_itx> i suppose that's just irc
[00:14:38] <andypugh> Though I never worked out why he was so active, as all his LinuxCNC stuff was fully functional and making money, and he wasn't involved in development.
[00:14:39] <Tom_itx> GammaX, he was making specialty bike sprockets etc
[00:14:57] <Tom_itx> i'm not involved in developement either
[00:15:16] <Tom_itx> are you planning the long trip to the fest?
[00:15:22] <Tom_itx> in june
[00:15:47] <Tom_itx> that would be a stretch for you i suppose
[00:15:59] <andypugh> Who me?
[00:16:02] <Tom_itx> yes
[00:16:10] <andypugh> Already bought the airline ticket.
[00:16:15] <Tom_itx> really??
[00:16:17] <Tom_itx> cool
[00:16:18] <andypugh> Aye
[00:16:24] <Tom_itx> it's in my home town
[00:16:44] <andypugh> I couldn't see the tickets getting any cheaper.
[00:16:52] <Tom_itx> no they never get cheaper
[00:16:59] <Tom_itx> unless you book standby
[00:17:22] <Tom_itx> were you at the last one?
[00:17:48] <andypugh> No, I have only ever met one other LinuxCNC user.
[00:18:08] <Tom_itx> i'm gonna try to drop by for part of a day at least
[00:18:24] <Tom_itx> i won't have alot to contribute but i thought it would be fun
[00:19:49] <Tom_itx> i've been by Stuart's place many times but never been inside
[00:19:54] <SWPLinux> it
[00:20:03] <SWPLinux> it's smoky, but has lots of machinery
[00:20:07] <SWPLinux> (Stuart's place)
[00:20:15] <Tom_itx> smoke from machines?
[00:20:18] <andypugh> Smoky?
[00:20:23] <SWPLinux> no, from cigarettes
[00:20:26] <Tom_itx> ahh
[00:20:33] <toastyde1th> Oi, what's best lightweight/solid small lathe, in the (12-16)x40 ran ge
[00:20:35] <andypugh> Is that still legal in the US
[00:20:44] <toastyde1th> ideally under 1k lbs
[00:20:55] <Tom_itx> not in public buildings
[00:20:58] <SWPLinux> yep. they have a sign on the front door that says that smoking is permitted on the premesis
[00:21:04] <andypugh> toastyde1th Get something made in the 1970s or earlier.
[00:21:19] <toastyde1th> andypugh, the problem is i'm sorting based on weight here
[00:21:33] <toastyde1th> there are a lot of very heavy small lathes (i know a good amount about heavy shit)
[00:21:54] <toastyde1th> I was hoping someone had a few specific models off the top of their head
[00:22:16] <Tom_itx> you're working on the ship machine shop right?
[00:22:22] <toastyde1th> yeah
[00:22:48] <toastyde1th> there are a few good mills in the thousand pound range, looking around at lathes
[00:23:25] <andypugh> Ah., well, for onboard a ship you need: http://www.lathes.co.uk/adcock&shipleycombination/index.html
[00:23:58] <toastyde1th> haha that probably weighs 10 tons
[00:24:09] <Tom_itx> the titanic probably had one
[00:24:16] <andypugh> Designed for use in boats though.
[00:25:09] <andypugh> Harrison M250 is a fairly compact proper lathe, and 785lbs
[00:25:09] <toastyde1th> it's desined to go into ships
[00:25:16] <toastyde1th> 3000gwt or larger
[00:26:13] <toastyde1th> will look up the harrison ,ty
[00:26:22] <andypugh> Here is the next size up (not a lot heavier) http://www.ebay.com/itm/13-19-x-25-Harrison-Model-M300-Engine-Lathe-/321039246777?pt=LH_DefaultDomain_0&hash=item4abf6e25b9
[00:26:42] <toastyde1th> twice as heavy
[00:27:20] <andypugh> Ah, yes, so it is.
[00:27:38] <toastyde1th> 800 lbs is a good weight

[00:45:11] <Tom_itx> yes

[00:45:33] <r00t4rd3d> lol
[00:45:36] <toastyde1th> probably a couple small ones, like an 8-10" manual 3 jaw, a faceplate, and a 4 jaw at the max swing size
[00:45:42] <Tom_L> shipping weight 1154: http://www.northerntool.com/shop/tools/product_40810_40810

[00:46:08] <toastyde1th> bench lathe is probably the way to go, save space
[00:47:23] <toastyde1th> i'd rather have more weight on the lathe than mill anyway
[00:47:41] <Tom_itx> i thought you found a mill but was a tad over your weight
[00:47:48] <toastyde1th> found one that was under
[00:47:50] <toastyde1th> 700 lbs
[00:47:53] <Tom_itx> oh
[00:48:38] <toastyde1th> I can drill and bore on a larger lathe
[00:48:42] <toastyde1th> far more gear
[00:48:49] <toastyde1th> not too much to mill
[00:49:22] -!- zlog has quit [Read error: Connection reset by peer]
[00:49:53] <toastyde1th> I found even smaller mills that look better built but they're all cnc-only
[00:50:21] <toastyde1th> true bench mount, which is ideal because it means it can integrate into the area better

[03:40:29] <kizer> okay i get it. well i can only wonder if linuxcnc is comparable to mastercam
[03:40:29] <generic_nick|2> i just machine it
[03:40:45] <Tom_itx> it depends on their post
[03:40:55] <Tom_itx> i wrote one for my smartcam for linuxcnc
[03:41:28] <Tom_itx> generic_nick|2, you didn't draw it?
[03:41:33] <generic_nick|2> no
[03:42:11] <generic_nick|2> i helped him design it so that i can machine it efficiently, but he did all the modeling

[13:38:36] <Gromits> I have a machine that has been running 2.5.2 without issues for some time. I think someone did a system update but I am not sure what might have gotten updated. Now Linuxcnc exits when it goes to launch my gladevcp panel.
[13:39:03] <Gromits> The errors are here: http://pastebin.com/g2CdL7dn
[13:39:53] <Gromits> I think the one that matters is: (gladevcp:1651): libglade-WARNING **: Expected <glade-interface>. Got <interface>.
[13:40:02] <Gromits> Anyone have an idea what this means?

[13:48:14] <Tom_itx> mine is using 1:2.6.4-build1
[13:48:26] <Gromits> what is at 2.6.4?
[13:49:13] <Tom_itx> what do you mean? ... remember i'm no linux guru :)
[13:49:38] <Tom_itx> that's the ver of libglade2-0 here
[13:49:49] <Gromits> ah, let me look at mine...
[13:49:57] <Tom_itx> i'm checking the package manager
[13:50:12] <Tom_itx> and my system should be fairly current with updates
[13:51:04] <Gromits> Mine is running the same 1:2.6.4-1build1 (notice 1 in front of build - does yours have that, or is it build1)?
[13:51:48] <Tom_itx> yes same
[13:51:50] <Tom_itx> i missed that
[13:52:29] <Tom_itx> and the glade ver is 3.7.0.is.3.6.7-Outbur
[13:53:28] Cylly is now known as Loetmichel
[13:54:40] <Gromits> Yep, I have the same glade as well....
[13:54:48] <Gromits> This was working fine yesterday.
[13:55:13] <Tom_itx> wiggle your ram chips and MB connections
[13:55:27] <Tom_itx> or look for something out of place
[13:55:29] <Gromits> When I came in this morning it looks like someone clicked update on the Update Manager panel. Can you run Update Manager and see if there are update to glade waiting for you?
[13:55:49] <Tom_itx> mine says when there are updates ready
[13:55:54] <Gromits> To glade?
[13:56:01] <Tom_itx> oh i dunno about that
[13:56:09] <Gromits> I dare you to update ;-)
[13:56:17] <Tom_itx> i should be current
[13:57:42] <Tom_itx> maybe the 'someone' shouldn't have admin rights
[14:00:46] <cradek> Gromits: did they update the whole os, or just the packages?
[14:01:00] <cradek> Gromits: if they updated the os, you will have to reinstall
[14:01:30] <Gromits> Not the OS, it is still at 10.04. But there are no update in Update Manager
[14:06:26] <L84Supper> does Ubuntu let you set "check for updates" to never?
[14:06:51] <cradek> gladevcp[1651]: segfault at 20 ip 01159a59 sp bff32b60 error 4 in libgtk-x11-2.0.so.0.2000.1[fdb000+3cd000]
[14:07:11] <cradek> in general you should be able to install updates to packages (but not update the OS version)
[14:07:23] <cradek> I agree gladevcp is crashing now
[14:07:27] <Tom_itx> that was why i suggested he wiggle his memory connections
[14:07:28] <cradek> did you reboot after the updates?
[14:07:37] <Tom_itx> mmm
[14:07:42] <Gromits> Yes, I have rebooted.
[14:07:59] <Gromits> You are seeing glade exit as well?
[14:08:16] <Tom_itx> remind me not to update
[14:08:20] <Gromits> Do you know what got updated?
[14:09:09] <Gromits> I found this on stackoverflow: http://stackoverflow.com/questions/2668618/python-glade-could-not-create-gladexml-object
[14:09:27] <Tom_itx> L84Supper, yes it's in 'startup applications preferences'
[14:11:03] <Tom_itx> System -> Preferences -> Startup Applications
[14:11:09] <Gromits> But, when I try to save as libglade it complains that a huge pile of object classes not being supported in libglade format. (and it crashes for other reasons seemingly related to that
[14:11:34] <L84Supper> don't give everyone admin rights or at least kill any auto updates
[14:12:16] <L84Supper> Gromits: who knows what else they did?
[14:12:51] <L84Supper> maybe they also decided to see what would also happen if you delete things
[14:13:09] <Tom_itx> cradek was apparently able to reproduce the error
[14:13:10] <Gromits> All the configs are there from what I can tell. I compared to a recent backup
[14:13:42] <Gromits> I am fairly sure this is an issue specifically with Glade
[14:13:52] <cradek> no I wasn't, I was identifying the important line from the big pastebin
[14:13:56] <Tom_itx> oh
[14:14:08] <L84Supper> yes, a few lines up from the bottom
[14:14:41] <cradek> you could try identifying the package that broke by reverting updates. this can be a little tedious but is generally possible
[14:15:03] <cradek> apt can install a specified version you specify using =
[14:15:25] <Gromits> Is the package that broke specifically libgtk-x11-2.0....?
[14:15:35] <cradek> maybe, maybe not

[14:55:25] <Gromits> has something to do with it.
[14:56:13] <Gromits> I comment that out and it comes up. Axis won't reload our file anymore when I touch off X/Y in our glad panel (the point of that variable), but at least it is working
[14:56:29] <Gromits> Why that worked fine yesterday and not today is a mystery...

[15:46:16] <tjtr33> i saw linear inductosyns in old APT programming book.
[15:46:25] <tjtr33> they >might< be mfctrd by std pcb techniques ( read: cheap linear scales of hi precision )
[15:46:26] <tjtr33> http://www.analog.com/static/imported-files/seminars_webcasts/813973100sscsect6.PDF
[15:46:47] <tjtr33> what i saw looked photoetched
[15:52:58] <tjtr33> have not scanned book yet but plates like these ( scale and reader head ) http://www.microcontrol.it/prodotti.html
[15:53:49] <pcw_home> With a minimum 5 mill trace width and a 10 mill loop spacing you get a 35 mill pitch (360 electrical degrees)
[15:53:51] <pcw_home> so you have to have pretty good interpolation
[15:56:02] <tjtr33> thx! i see the pix abobe is made by Ruhle ( good ol name )
[15:57:22] <tjtr33> re: interp, the recent chips mentioned for resolvers might handle the sine interp ( ic haus .de ?)
[15:57:31] <pcw_home> dont know where the best pitch tradoff is (larger pitch mean larger signal for so better S/N ratio)
[15:58:39] <pcw_home> I think those are DC interpolaters so may need a sync detector front end
[15:59:14] <pcw_home> synchronous detector I should say
[16:00:07] <tjtr33> i saw them on moog jig bores, not a fast contouring machine
[16:00:32] <tjtr33> just a thought :)
[16:01:19] <pcw_home> You probably will not get really high resolution but they are very tough (they will cheerfully run under water made correctly)

[16:59:17] <tjb1> stamos is brand right
[16:59:43] <IchGuckLive> yes
[17:00:27] <tjb1> has to be a reason for different price :P
[17:00:37] <tjb1> especially one that extreme
[17:01:15] <IchGuckLive> i unboxed it opend the case got the relay placed and got into work
[17:01:39] <tjb1> I can get a hypertherm 45 right now for 1235.89 euro

[17:02:34] <IchGuckLive> on one nozzle 1.2mm
[17:03:22] <IchGuckLive> china suprise hase been that the tols are inside the case
[17:03:51] <IchGuckLive> how in this world opens the warrenty and 30 screws to get the wrenches and bits
[17:04:05] <IchGuckLive> Suprise suprise
[17:04:47] <IchGuckLive> so if you(postman) turns the packet upside down it is getting you a nice firerworks on 380V
[17:05:23] <IchGuckLive> tjb1: i will get you if it hits 200h of cutting
[17:05:46] <tjb1> tols?

[17:07:29] <tjb1> Wait, what is getting on 380v?
[17:07:54] <IchGuckLive> the plasma cutter gets 3phases
[17:08:10] <IchGuckLive> L1 l2 l3
[17:08:22] <tjb1> and something is loose on the inside?
[17:08:50] <IchGuckLive> yes i found 3 wrienches NEW and 4 bits
[17:09:15] <tjb1> H
[17:09:17] <tjb1> ah

[17:10:43] <IchGuckLive> but as i sayd insider the seald case that is china
[17:11:12] <IchGuckLive> loos is not correct
[17:11:27] <IchGuckLive> inside wax like material clue

[21:51:36] <diginet> this is slightly OT, but does anyone here know anything about powder metallurgy?
[21:51:40] -!- ravenlock has quit [Quit: Leaving]
[21:51:44] <andypugh> 4QD: http://www.4qd.co.uk
[21:52:33] <diginet> I'm trying to figure out how one introduces metal powder into a vacuum chamber, wouldn't that necessarily trap a ton of gas in all the pores?
[21:52:55] <andypugh> diginet: I don't think I know much about it, but then I am comparing my knowledge to that of the woman I shared my office with who was doing postdoctoral research on the subject.
[21:53:23] <diginet> ah, that's okay lol
[21:53:38] <andypugh> It's a powder, not a foam. Nowhere for gas to hide.
[21:53:44] <diginet> I just can't find out how that is done, I haven't seen anyone address it
[21:53:56] <diginet> I know, but I mean. . .surely some would?
[21:54:12] <andypugh> Why? How?
[21:54:34] <diginet> well I mean, if the particles are big enough, wouldn't some just get trapped in little crevices?
[21:54:49] <diginet> plus, more surface area, so more ways for gas to get trapped in oxide layers
[21:55:21] <andypugh> Well, there is quite a lot of gas in any oxide :-)
[21:55:51] <diginet> I mean, besides oxygen
[21:55:57] <diginet> dissolved atmospheric gases
[21:56:37] <andypugh> I think that you are trying to avoid macro-sized bubbles. There is likely to be an equilibrium level of dissolved gas in any metal, matching the composition of the atmosphere.
[21:57:16] <diginet> yeah, that's true, but wouldn't it be much more of a problem with, as I mentioned, the much higer surface area?
[21:57:17] <largecheesepuff> Tom_itx: thanks...
[21:57:27] <andypugh> The vacuum processing of powder met is just so the metal _can_ coalesce, not to create a fully degassed end product.
[21:57:50] <diginet> sure, but you still need to get a high vacuum
[21:58:01] <diginet> plus there are processes which fully melt it, like electron beam melting
[21:58:09] <andypugh> I doubt they get a really high vaccum.
[21:58:57] <andypugh> The vapour pressure of the metal itself at the sintering temperature is likely to make it quite a low vacuum.
[21:59:33] <largecheesepuff> hmm seems like it should be correct..

[22:37:11] <andypugh> It rained all the way to work today. I was so glad that, at 11pm last night, I decided to finish reassembling the R1. I have good wet-weather gear for the motorbike, I have nothing suitable for cycling in.
[22:38:03] <andypugh> And I just won a really stubby Renishaw stylus, so now I can probe thivk things as well as very, very thing things.
[22:38:12] <JT-Shop> I was glad we trailered the Spyder to SpyderFest, it would have been a cold wet ride home and the wife could not have napped part way
[22:38:22] <JT-Shop> nice
[22:39:44] <andypugh> Actually, the 75mm probe leaves me about 4" over the bed so it's not hopeless, but 6" with the short probe sounds better.
[22:40:06] -!- ravenlock [ravenlock!~ravenlock@enlightenment/developer/ravenlock] has joined #linuxcnc
[22:43:17] <andypugh> I am new to probing, and keep thinking about algorithms. I wonder how legitimate it would be to probe down to break, then drag laterally until make to find the top first, then the edge of the stock?
[22:44:58] <L84Supper> diginet has left but what was he really asking about?
[22:45:15] <andypugh> Powder metallurgy
[22:45:37] <andypugh> It's a way to make alloys of metals with very different melting points.
[22:45:44] <L84Supper> you put power in a chamber and create a vacuum, what was he missing?
[22:45:56] <JT-Shop> kind of a rough probe to get the basic dimensions?
[22:46:10] <andypugh> He seemed convinced that gas would get trapped in the powder.
[22:46:32] <L84Supper> if it already was, did he want to remove it?
[22:46:44] <andypugh> JT-Shop: Yeah, it was the dragging the probe across the surface part that I was wondering about.
[22:47:25] -!- pfred1 [pfred1!~pfred1@unaffiliated/pfred1] has joined #linuxcnc
[22:47:37] <andypugh> L84Supper: Actual pockets of gas in the powder was his concern. Seems unlikely to me.
[22:48:30] <L84Supper> andypugh: depends on his source for powder, but it would be negligible
[22:48:35] <andypugh> L84Supper: Here's an idea. Selective laser sintering of multiple metal powders to have alloy constitiuents varying within the part.
[22:50:26] <andypugh> L84Supper: No, how concern was that if you mixed the powder in atmosphere, then the gas would get trapped between the grains when you tried to degas. I guess it might take some time to diffuse out, but the powder won't have any closed porosity.
[22:52:28] <pfred1> laser scinters lay the powder down in layers
[22:53:06] <andypugh> You might be surprised how far you can make elements move in a post-sinter heat treatment.
[22:53:18] <L84Supper> andypugh: yeah, you could agitate the powder to release any gas trapped in between grains
[22:53:38] <pfred1> L84Supper the way that stuff gets laid down it is like packed
[22:53:46] <andypugh> L84Supper: I think it is probably pressed into shape by that stage?
[22:54:21] <andypugh> Just to be clear, powder met and DLS are rather different processes.
[22:55:02] <andypugh> Powder met you press a metal powder mix into shape, then heat until the metals all diffuse into each other.
[22:55:32] <andypugh> Juat a bit below the meltiong point of the main constituent, I think.
[22:55:40] <L84Supper> what was diginet doing>
[22:56:10] <andypugh> He was asking about Powder Metalurgy. I doubt he is doing either.
[22:56:50] <L84Supper> if you want to degass a powder you agitate while in a vacuum
[22:56:58] <andypugh> http://en.wikipedia.org/wiki/Powder_metallurgy
[22:57:48] <L84Supper> yeah, been around for a while
[22:57:50] <andypugh> I have an idea that the typical milling machine hold-down kits are powder met. I don't know why I think this.
[22:58:10] <andypugh> L84Supper: 3000BC in fact :-)
[23:01:38] <r00t4rd3d> another 250 spent today on aluminum parts and pieces :/
[23:01:57] <L84Supper> DLS is another patent mine field, another reason we went to China
[23:03:20] <L84Supper> there are many techniques that you probably won't see in DLS printers for years due to patent trolls
[23:04:01] <andypugh> Has anyone done much work on the GGG / MIG crossover?
[23:05:52] <L84Supper> not really, there's this big boom in GGG right now just to print crap
[23:07:44] <L84Supper> but there is work going on with hybrids that combine different techs since there is no one perfect tech
[23:08:24] <pfred1> nanotech
[23:09:08] <L84Supper> you might start seeing printers that print parts with metal cores that have polymers on the outside
[23:09:58] <L84Supper> for example a metal flashlight body with plastic grip
[23:10:48] <L84Supper> printers like these are will really revolutionize manufacturing if they print a part in seconds and at low cost
[23:11:16] <pfred1> as opposed to now where they take forever and cost a fortune?
[23:11:18] <WalterN> L84Supper: for fibre optic cables... can I get one thats big enough and a single strand?
[23:12:30] <L84Supper> IMHO the GGG hype is giving people a bad impression of what 3dp is all about
[23:12:33] <WalterN> or would multi-strand not be an issue?
[23:13:37] <L84Supper> WalterN: multi-strand of multi-mode?
[23:13:43] <L84Supper> of/or
[23:13:47] <WalterN> no idea

[23:15:06] <L84Supper> WalterN: you need a fiber with the right connector on the end
[23:16:13] <WalterN> is SMA 905 common

[23:16:59] <WalterN> and what does multi-mode mean?

[23:23:26] <JT-Shop> http://www.youtube.com/watch?feature=player_embedded&v=HKEuzxC4eGc
[23:23:37] <WalterN> you can kinda see it there
[23:23:38] <JT-Shop> it finally quit here
[23:24:11] -!- tmcw has quit [Ping timeout: 258 seconds]
[23:24:17] <WalterN> or should I take a better picture?
[23:25:23] <andypugh> WalterN: Multi-mode fibre can carry more than one wavelength losslessly
[23:25:27] <L84Supper> andypugh: I'd say that has been lots of techniques already worked out for DLS, nut you won't be seeing them in printers anytime soon
[23:26:10] <andypugh> Is this my day to look clever? My PhD was optical fibers, then I became a metallurgist :-)
[23:26:23] <L84Supper> nut/but the OEM's don't cooperate and there are so many patents that overlap it's going to make the patent wars over smart phones look small
[23:26:33] <andypugh> Quick, somebody ask about skin grafts :-)
[23:26:38] <Tom_itx> heh
[23:27:00] <JT-Shop> what's a farkle?
[23:27:11] <Tom_itx> a sparklie fart
[23:27:25] <L84Supper> meanwhile in China they will just take over the tech the same as they did with computers
[23:31:04] <Tom_itx> JT-Shop, when you get a chance could i take a look at your touchoff buttons?
[23:31:10] <Tom_itx> no rush...
[23:31:16] <Tom_itx> gonna watch a show right now anyway
[23:31:18] <JT-Shop> you bet
[23:31:26] <JT-Shop> tomorrow then?
[23:31:34] <Tom_itx> i can check the logs
[23:31:44] <Tom_itx> i'll be milling later this evening anyway
[23:31:54] <Tom_itx> or tomorrow
[23:31:56] <Tom_itx> either way
[23:32:26] <JT-Shop> ok, let me fire up the lathe so I can copy the configs
[23:32:46] <Tom_itx> i'll check in after bit
[23:33:40] <Tom_itx> bourne is all queued up
[23:34:29] <JT-Shop> actually it should be on my web site

[23:39:09] <L84Supper> andypugh: there are lots of medical apps that require DLS with titanium

[23:53:58] <PCW> andypugh it appears that setsserial does not check the firmware name vs remote device name
[23:55:15] <andypugh> No, I thought I could assume competence, and could not necessarily assume file naming
[23:55:36] <andypugh> C is a terrible place to try to spot partial string matches.
[23:55:47] <PCW> Its not terribly dangerous
[23:56:48] <PCW> except that writing too big firmware may wipe the (simulated) EEPROM defaults
[23:56:58] <andypugh> Is there any danger of wrong-firmware over-writing boot code?
[23:57:02] <JT-Shop> yikes
[23:57:06] <PCW> No

[23:57:43] <PCW> but it could overwrite the EEPROM defaults, so you would have to fix those to recover
[23:59:13] <PCW> take a look at my (fairly crappy scripts) when you get some time (must be late there)
