00:55 rue_more hahah I should use my flash chip programmer to program a z80 flash chip programmer
01:08 rue_more well apparently I need some better ihex tools
01:36 rue_more http://www.intermodalics.eu/sites/www.intermodalics.eu/files/images/image.U03B7V.intext400.png
01:36 rue_more ^^ am I the only one that sees PVC pipe and T fittings?
03:17 theBear i'm not old, just bitter and jaded :-)
03:20 theBear course you can avoid one of those by just not licking me
04:57 de-vri-es armyofevilrobot1: indeed, the kinect seems accurate enough, but it can't see anything in closer by then about half a meter
09:21 rue_more hmm
09:22 rue_more sdcc cant handle io arrays well
09:22 rue_more you have to define a name for every port
09:25 rue_more I was able to overclock the z80 to 6Mhz yesterday :)
12:02 GuShH rue_more: what could this be from? http://gushh.net/tmp/dscn5523f.jpg seems a truck had an accident nearby, that was left over, and some diesel.
12:03 GuShH threads are flattened on the other side, must have been a nice impact.
12:04 GuShH not sure how that fell off
12:27 SlaveToTheSauce maybe whatever it was threaded into was sheared in half?
12:27 SlaveToTheSauce across the hole
12:30 SlaveToTheSauce car accidents are pretty scary
12:30 SlaveToTheSauce great way to transfer a megajoule of energy in a fraction of a second
13:00 Terrenkt SlaveToTheSauce, I don't think i've ever seen that happen in particular, except as an engineered failure point. and if that was the case, there'd be some pretty major damage to the threads
13:02 SlaveToTheSauce i am under the impression it's not uncommon for a major accident to crack an engine block for instance
13:02 SlaveToTheSauce and in the event of that occurring i think it's safe to assume the crask would go through one or more tapped holes, as the weakest points in the structure
13:02 Terrenkt GuShH, is there any damage to the threads?
13:02 Terrenkt then that wouldn't be a shear, it'd be a tensile fracture
13:03 SlaveToTheSauce right ok
13:03 SlaveToTheSauce my mechanical-fu is not strong
13:03 Terrenkt it's a bit of semantics but semantics are important
13:03 SlaveToTheSauce agreed
13:03 Terrenkt <-||->
13:03 Terrenkt that would be a tensile fracture
13:04 Terrenkt ->
13:04 Terrenkt <-
13:04 Terrenkt would be shear
13:07 SlaveToTheSauce also i don't think i've seen you here before
13:07 SlaveToTheSauce oh you're hyratel
13:11 Terrenkt hi
13:11 Terrenkt this is my third-backup nick
13:11 GuShH Terrenkt: yes damaged
13:11 Terrenkt because I'm too lazy to renick every time my connection bounces
13:11 GuShH I like parts with a story, I just wanted to know what it was from (general idea)
13:12 GuShH missed the accident though
13:12 GuShH (not that I wanted to see any gore)
13:12 GuShH skid marks tell a story...
13:13 GuShH there's always a chunk of bike or car near the highway.
13:13 GuShH the scary chunks are truck tyres
13:13 GuShH when the entire thread pops off and slams you on the windshield.
13:13 GuShH tread*
13:13 Terrenkt oh, thrown gatorbacks
13:13 Terrenkt *shudder*
13:14 GuShH I see a lot of that.
13:14 GuShH also small stones picked up by trucks...
13:15 GuShH anyway those diesel puddles are the worst enemy for a motorcycle, even a car on a corner...
13:15 GuShH I thought they had to clean those up
13:16 GuShH seems when they're not "big enough" they don't bother.
13:16 Terrenkt I don't know if they'll erode asphalt like gasoline
13:17 GuShH they'll erode you that's for sure.
13:18 ShH once noticed a combination wrench on the highway, but couldn't pick it up as the traffic speeded up heh M8-M10 or so, would be quite nasty if that thing hit you... must have fallen from a motorcy
13:19 GuShH as for bolts and sparkplugs... specially on strings... that's what they'll use from a bridge to make someone stop and steal their car, happened so many times they had to fence up every single bridge in town and they still manage to work around it.
13:20 Terrenkt 6_o
13:20 GuShH also stones, that's what the ghetto thieves use... most people stop to see what happened, that's when they get them.
13:21 GuShH another way they steal cars is they tie cans to the chassis, so it makes noise when you accelerate, then stop to see what's going on...
13:21 GuShH yeah crooks around town know all the tricks.
13:21 GuShH medieval times were nicer, they would cut your hand off for stealing some olives.
13:21 GuShH now adays minors go in and out the same day.
13:22 GuShH Or the classic in Argentina... red light, with the windows down... they'll shove their arms in and grab whatever they can, soon the green light is on and you can't do shit about it.
13:23 ShH votes pro
13:25 Terrenkt GuShH, grab their arm and then accelerate
13:26 Terrenkt hook elbow over the door pillar
13:29 GuShH Terrenkt: oh there are so many things I would do if it happened to me
13:29 GuShH most are unnarmed.
13:30 GuShH so it's fair game.
14:37 GuShH rue_more: you gotta see this...
14:37 GuShH I rued it like I never rued before.
14:39 SlaveToTheSauce did you rue the day
14:39 GuShH yes I did.
14:39 GuShH one sec.
14:42 GuShH needed to cut some squares out of 6061, not wanting to use the chop saw to avoid the time it takes to clean up the cuts, so...
14:42 GuShH It's one of those things that just fall into place on their own, you just guide them. I was looking for a slitting saw (hss, small diameter) but they were rather costly new... and I couldn't find good used ones, so I decided to use a metal cutting skil saw blade, I already had it but never used it on the skilsaw...
14:42 GuShH anyway, one big bolt and two nuts later, chucked it on the 3 jaw... it wasn't running very true (not cutting on all teeth, due to the bolt not being a precision shaft) but... the result was pretty damn good, in fact better than expected... not very fast cutting though, I was going slow on both speed and feed, but chips were flying... no gumming
14:42 GuShH shiny cut.
14:43 GuShH 5 bucks vs 50 bucks for the real blades (which I admit are thinner, precision and proper hss... but still)
14:43 GuShH tablet pic but you get the idea http://gushh.net/tmp/p_20140528_161718f.jpg that's for a 7" or so skilsaw
14:44 GuShH dangerous doesn't begin to describe it.
14:46 SlaveToTheSauce hahah
14:46 SlaveToTheSauce no, mister workpiece. I expect you to die.
14:48 ShH is proud of this kl
14:49 GuShH works, of course I don't recommend holding the part parallel near the end of the cut, better let it cut until there's a few thou left and just break it free, then mill it absolutely flat instead.
14:49 GuShH don't try this at home.
14:51 GuShH bbiab, gotta change underwear after this.
14:54 GuShH not accounting for the last portion where it's off, the whole section is only 0.01mm off
14:54 GuShH which is surprisingly good given the circumstances.
14:54 GuShH so it's almost square.
14:55 ShH doesn't have a proper micrometer to test it with, but that's just irrelevant and a fun f
14:57 GuShH as long as the toolpost is trammed to the chuck, it's all good
14:58 GuShH V slits could also be cut using this method, it occurs to me.
15:53 Terrenkt GuShH, is there anything you can do with that jig that you couldn't with a traditional tablesaw?
15:54 GuShH Terrenkt: I don't have a tablesaw... and well, you have a finer degree of control of the feeds and positioning
15:54 Terrenkt what if you put a lathe feed assy on a tablesaw?
15:55 GuShH why would you?
15:55 GuShH use a mill!
15:55 Terrenkt lacking a mill
15:55 GuShH but sure, you could try all sorts of things
15:55 GuShH including clamping a skilsaw to a workbench and... wait that's even more dangerous.
15:55 GuShH a tablesaw with the right blade is a good alternative, if you have one
15:55 Terrenkt one thing that occurs to me is that most tablesaws have a cut depth wheel
15:55 GuShH they're rather expensive where I live, and contractor saws (at least the ones available) are complete trash
15:55 Terrenkt I've more than once adjusted depth during a cut
15:56 GuShH Terrenkt: yeah they do
15:57 GuShH I have a chopsaw I use for cutting stock.... would like to have a horizontal band saw (metal cutting) but meh.
15:57 GuShH the one I would like to have is the wet type, which is a lot more expensive.
15:57 Terrenkt chopsaw? or mitersaw?
15:57 GuShH chop, again I don't work with wood.
15:57 Terrenkt gotcha
15:57 GuShH very rarely.
15:58 Terrenkt all my knowledge/experience is in wood and aluminum
15:58 GuShH I like wood, I just don't have space for the proper tools.
15:58 GuShH I have a wood lathe and some basic hand tools, that's all
15:58 Terrenkt what do you consider wood tools?
15:59 GuShH planes, chisels, skilsaw, sander...
15:59 GuShH well the skil works on steel with that type of blade, if you dared to.
15:59 GuShH http://saw.by/sites/saw.by/files/articles/bs-712n.jpg they take quite a bit of space.
15:59 Terrenkt tablesaw, mitersaw, coping saw, electric jigsaw...
15:59 GuShH I have a jigsaw, rarely use it
16:00 GuShH oh and a handheld router
16:00 GuShH just 1/4"
16:00 Terrenkt if your jigsaw is of middling to decent quality, a handheld CircSaw (you say skilsaw) wis largely redundant
16:00 GuShH hey skil invented it!
16:01 GuShH and it's the saw that built 'murica
16:01 ShH chuc
16:01 Terrenkt ohgod not this
16:01 ShH co
16:01 GuShH the speed with which you can cut is much faster with the circular saw, and nicer for long parallel cuts IMO
16:02 GuShH the finish is also nicer, given the speed
16:02 GuShH even just using carbide framing wheel
16:02 Terrenkt unless you're doing something like turning table legs, a for-metal lathe with the proper fittings is just as servicable for wood
16:02 GuShH or disc, saw, whatever you want to call it
16:02 Terrenkt this is true
16:02 GuShH nah my metal lathe won't touch wood, ever.
16:02 Terrenkt no?
16:02 GuShH it's a chinese wood lathe I got, nothing special... with copy carriage, which needs some tweaking
16:03 GuShH sometimes I turn wood to relax.
16:03 GuShH need a handle or feeling creative... turn wood.
16:03 Terrenkt ah gotcha
16:03 GuShH but I need to come across the right chunk of wood.
16:03 Terrenkt justa Nothin' Special?
16:04 ShH is not an ar
16:04 GuShH I would like to make segmented stuff...
16:04 GuShH but that requires a good planer
16:04 GuShH and a tablesaw
16:04 GuShH unless you could square things up on the wood planer?
16:04 GuShH jointer type
16:05 Terrenkt i do joinery truing on the tablesaw
16:05 GuShH for small stuff maybe an electric planer would do
16:05 GuShH and lots of patience.
16:05 GuShH my only hand plane sees very little use.
16:06 GuShH Terrenkt: so is all of your woodworking commercial or just a hobby?
16:06 Terrenkt hobby
16:06 GuShH woodgears fan?
16:06 GuShH heh
16:06 Terrenkt nah
16:07 Terrenkt but I could make an indexing jig for the tablesaw
16:07 Terrenkt but nah - heavy duty camp furniture
16:07 GuShH I guess the only reason he's passionate about wood is because his dad was and he grew up in that environment
16:07 GuShH plus had all tools at his disposal
16:08 GuShH his dad made rather crude looking furniture
16:08 GuShH (not saying it didn't look good, but it wasn't high end stuff)
16:08 Terrenkt similarly here
16:09 Terrenkt for context, the tent we take, the roof canvas alone weighs 80 pounds
16:09 GuShH I like the big tables that are made out of a huge slab of tree
16:10 GuShH real wood, showing real grain.
16:10 Terrenkt eh?
16:10 GuShH whenever I see MDF I want to take a chainsaw and turn it back to dust.
16:10 GuShH http://www.dumonds.com/images/2008%20IMAGE%20FILES/custom_dining_table_WALNUT_1.jpg
16:10 GuShH something like that, but not that particular one...
16:10 Terrenkt h. yeah, agreed
16:10 Terrenkt dats purdy
16:10 GuShH http://www.dumonds.com/images/Blocks/DSC_0089.jpg
16:10 GuShH that I like.
16:11 Terrenkt bet it weighs a ton though
16:11 GuShH don't know what type of wood that is
16:11 Terrenkt we have to have 'abusable' tables
16:11 GuShH most actual wood furniture I own is lightweight compared to MDF equivalents
16:11 GuShH or whatever particle board they use
16:11 GuShH don't know what's the latest trend in cheap furniture... other than maybe hollow with cardboard honeycomb structures (ikea)
16:12 Terrenkt flakeboard
16:12 GuShH aka fakeboard?
16:12 Terrenkt the leftovers from truing a treetrunk for plywood mfr
16:12 GuShH I don't like the stuff
16:13 GuShH a bit of humidity and...
16:13 Terrenkt flump
16:13 GuShH waferboard is a bit more stable?
16:13 GuShH the coarse stuff
16:13 Terrenkt it's better than dustboard
16:13 Terrenkt yeah
16:13 GuShH I would consider that for an abusable work bench
16:14 Terrenkt mmmh
16:14 GuShH but maybe splinters...
16:14 Terrenkt only if you don't need it True
16:14 GuShH well, if it's to be abused..
16:14 Terrenkt point
16:14 Terrenkt but slap some porch-floor paint down on it.
16:14 GuShH you'll beat it into trueness.
16:14 Terrenkt hah
16:14 GuShH and back to hell.
16:14 Terrenkt or make it slough
16:15 GuShH https://woodgears.ca/jointer/planer_snipe.html this guy uses dial indicators on wood
16:15 GuShH I have no words.
16:16 Terrenkt whyfor
16:16 ShH sh
16:18 GuShH maybe he should get into metal working if he likes to play with instrumentation.
16:18 Terrenkt some of the denser hardwoods work more like a hard nonferrous metal
16:20 Terrenkt and for those, it's not unlike working with brass in the tooling
18:55 _moon hello anyone around?
18:57 SlaveToTheSauce no
19:00 ace4016 yes, no, maybe. I don't know. Can you repeat the question?
19:27 _moon thats like in the old cartoon where a guy knocks a the door and the one inside says no one is home
19:29 _moon i was asking around here yesterday
19:29 _moon about my php problem
19:29 _moon everyone said php wasnt verry good
19:29 LoRez have you seen the php hammer?
19:29 GuShH how is this a php channel?
19:29 GuShH o.o
19:30 GuShH the problem with php is php, problem solved. don't use php
19:30 _moon yes
19:30 LoRez come on now GuShH, we all program our bots in php
19:30 _moon well i trien running some stuff in perl
19:30 GuShH yes but SECRETLY.
19:30 LoRez oh, yeah, fight club rules
19:30 GuShH such as python, I don't want anyone to know I use it. ruby is way more shameful though.
19:31 _moon and i got no results agian with perl
19:31 GuShH rue_more: got in the groove, cut a ton of parts in no time with that setup... awesome.
19:32 GargantuaSauce pushing your luck eh
19:32 ShH sh
19:32 GuShH that saw is rated for 10 times the speed I'm running it at.
19:32 GuShH that's an M16 bolt...
19:33 _moon i was hoping some one might know why a guy could echo shit to /dev/lp0 and have it work but php and perl scripts do nothing
19:33 GuShH I don't see anything wrong with it, other than the bolt needs the threads turned down for most of it's length for proper gripping
19:33 GuShH _moon: depends on the rights php has on that system
19:33 GargantuaSauce _moon: probably because piping stuff in bash is significantly more sophisticated than just opening the device and writing crap
19:34 GargantuaSauce you have to figure out what the shell is doing that you aren't
19:34 Triffid_Hunter _moon: strace is your friend
19:34 GargantuaSauce there are going to be more syscalls involved
19:34 _moon what is strace
19:34 Triffid_Hunter nope, /dev/lp0 you can just open and write, works perfect every time I've tried it
19:34 _moon i thought it would be simple ish iv had it work in c
19:35 GargantuaSauce well the php runtime is evidently doing something different
19:35 GuShH rue_more: once everything is locked down you can start making duplicates in no time by turning the part around and facing it, in the end I got a tall stack of relatively accurate blocks for what I'm doing.
19:35 _moon yeah somthing is stopping me
19:35 _moon im going to google or man strace
19:37 Tom_itx system trace
19:39 Triffid_Hunter _moon: what does perl -e 'open(F, "+<", "/dev/lp0") or die "$!"; printf F "blah\n"; close F;' do?
19:40 _moon gives me a > prompt
19:41 e_more dashes off to try out his out() function on the Z80 motherb
19:41 _moon is it the "+<" hat gives me a promt
19:42 _moon shit are you firing up the z80 computer
19:43 Triffid_Hunter _moon: you've missed a quote
19:44 _moon thats why i have a prompt?
19:44 Triffid_Hunter yes
19:44 Triffid_Hunter bash is waiting for you to provide the rest of the command
19:44 _moon oop the printer twitched
19:44 _moon exitment
19:44 _moon can you explain
19:45 Triffid_Hunter _moon: well duh, we just wrote some data to it
19:45 _moon yeah but whats the diff in what i was trying to do
19:45 _moon i show u the code
19:46 _moon open o, ">", "/dev/lp0";
19:46 _moon print o "durp";
19:46 _moon close o;
19:46 Triffid_Hunter _moon: you didn't send a newline. printer is waiting for the rest of the command
19:46 _moon hmm
19:46 Triffid_Hunter _moon: also, you should open ... or die "$!" so it spits an error if open fails
19:47 _moon i dont usualy do that
19:47 _moon and iit works but when i do its a \r
19:47 Triffid_Hunter _moon: you haven't had it work yet either
19:47 _moon well from echo
19:47 Triffid_Hunter _moon: \r is carriage return, only windows uses those
19:47 Triffid_Hunter _moon: echo adds a newline. echo -n if you don't want it to
19:47 _moon o
19:48 _moon so i will try to add a \n to the code of mine
19:49 _moon ok you got me
19:49 _moon it werks now
19:49 Triffid_Hunter :P
19:49 _moon thanks hay
19:49 _moon so now how does a guy execute perl with apache
19:50 _moon i think i installed the module properly lat night
19:50 Triffid_Hunter _moon: stick it in cgi-bin and call appropriate url.. you need to print content type and two newlines before body of document
19:50 _moon i dont have a cgi-bin directory
19:51 Triffid_Hunter add use CGI::Carp qw/fatalsToBrowser/; to the top of your file so any errors can show up in your browser instead of just getting 503 service unavailable and having to trawl apache logs
19:51 _moon ok
19:53 Triffid_Hunter _moon: http://triffid-hunter.no-ip.info/img if you want an example of a perl cgi script
19:53 _moon ok thanks
19:54 _moon so theese use s' in the beguining is that loading modules?
19:55 Triffid_Hunter _moon: yes. with perl you should always use strict. Data::Dumper is extremely handy for debugging, and CGI is handy for cgi stuff. there's about a zillion others available, see cpan
19:56 _moon ok
19:56 _moon i followed an instruction on the internet last night cpan CGI , i gather i instlled the cgi modules?
19:56 Triffid_Hunter yes
19:57 _moon cpan is a manager for perl moddules then?
19:58 Triffid_Hunter _moon: yes
19:58 _moon ok
19:59 _moon so now do i just make a folder called cgi-bin
19:59 Triffid_Hunter _moon: google a dozen or so mod_perl tutorials.. mod_perl itself should come with some docs
20:00 _moon ok i try to work with that
20:00 _moon thanks alot
20:00 Triffid_Hunter good luck, and have fun :)
20:04 _moon i will bye
20:10 rue_more been wondering what to make the z80 do
20:10 rue_more its slower than an avr, but lots more io and ram
20:10 Terrenkt does it have built in WROM?
20:11 Terrenkt or is that polled for externally
20:12 rue_bed I have 32kbytes ram and 32kbytes rom on it, I used bios flash chips
20:13 Triffid_Hunter rue_bed: get one of those gameboy carts with a flash chip in it, should give you several meg of rom
20:13 Triffid_Hunter and maybe several banks of 32k sram
20:13 rue_bed so the memory space is full, but I have 65535 io ports available
20:14 rue_bed I used a 2M bios flash chip
20:14 rue_bed and a 256k sram cache chip
20:14 rue_bed its only got 16 bit address bus
20:14 Triffid_Hunter rue_bed: ah, and just haven't hooked up the upper address bits to a bank selector?
20:14 rue_bed bit 15 selects rom or ram
20:15 Triffid_Hunter oh, 256kbits = 32kbyte
20:15 rue_bed thats all you get with 16 bits
20:15 Triffid_Hunter rue_bed: nope. you run bits 14,15 to a bank selector which is hooked into I/O, so you can switch out the 8k blocks at 8k,16k,24k for an 8k page of either ram or rom
20:16 rue_bed 5 chip system, z80, bios flash, ram, 7432 decoder, and 7404 for misc
20:16 Triffid_Hunter keep the lower 8k for kernel/system
20:16 rue_bed I hate paging
20:16 Triffid_Hunter rue_bed: I hate 16 bit address space more ;)
20:16 rue_bed none the less, I'm not sure what to use it for
20:17 Triffid_Hunter rue_bed: memory-mapped peripherals are good fun :P
20:17 rue_bed when you have 16 bits of io space?
20:17 Triffid_Hunter hook up another couple of sram as a video buffer with page flip
20:18 rue_bed oh I put an isa slot on it
20:18 rue_bed its flashing leds on a port 80 diagnostic card now
20:18 rue_bed so harddrive io is easy
20:19 Triffid_Hunter well hard drives were always easy, they're what, a direct 8 byte io port or so?
20:19 rue_bed a few
20:19 Triffid_Hunter "hard drive controller" was mostly an address decoder/passthrough for ISA from memory
20:19 rue_bed which is what made it easy to have an avr programmer operate off one
20:20 Triffid_Hunter yep
20:20 rue_bed I'm not sure about the video cards I have
20:20 rue_bed never initialized one manually
20:20 Triffid_Hunter rue_bed: curious thing about IBM-PC architecture is that the video bios starts first, inits the card then invokes system bios
20:21 Triffid_Hunter so if you're trying to run your vid from a different arch it may be a total crapshoot
20:21 rue_bed I can operate the chipset manually, it just might not be fun
20:24 rue_bed I was all excited about getting a serial card going till I realized that my board has no -12V
20:24 Triffid_Hunter max232 :P
20:25 rue_bed I have +12 I was trying to think of a simple inverter
20:25 Triffid_Hunter rue_bed: capacitor charge pump works fine for the max
20:25 rue_bed cant make one in half the space
20:26 Triffid_Hunter 555 and a couple diodes
20:26 rue_bed mmm

21:51 spiteball Any recommendations on where to get inexpensive parts, like wheels, gear, belts, motors, etc?
21:51 Triffid_Hunter spiteball: toyworld, 3d printer
21:53 spiteball Where's that based out of?
21:55 rue_more take stuff apart, its free
21:56 Triffid_Hunter spiteball: what? toyworld? there's one in almost every supermarket.. might have a different name
21:58 spiteball oh I thought you meant that was an actual store or website
21:59 Triffid_Hunter spiteball: nope, any place that has kid's toys will have a whole section with tanks and robots and stuff
21:59 Triffid_Hunter and sometimes a bargain bin too
22:01 spiteball has anyone on here bought from RobotShop.com?
22:03 rue_more HP inkjets have 3 great wheels in them, sometimes 5
22:05 Tom_itx i got a new epson in the attic i should tear apart
22:05 rue_more :)
22:05 Tom_itx cartriges cost too much for it
22:05 rue_more I have 5 commercial multifunctions on the deck I should tear apart
22:05 Tom_itx and they were tiny refills
22:06 Tom_itx certainly not worth what the asking price was for them
22:06 spiteball I need propellers, some gears, and two regular motors, and some pneumatic actuators
22:06 Tom_itx i got 3 shelves of crap i'm gonna toss out
22:07 rue_more pneumatic atuators means pneumatic valves
22:07 rue_more pneumatic valves $$$$$
22:07 rue_more Tom_itx, we gonna ship it to me?
22:07 rue_more fr4
22:07 Tom_itx once i get it sorted and boxed
22:07 Triffid_Hunter spiteball: hobbyking probably has most of that, except the pneumatics
22:07 Triffid_Hunter spiteball: what do you want pneumatics for?
22:07 Tom_itx no not the fr4 unless you wanna pay for it
22:07 rue_more :)
22:07 Tom_itx costs too much to ship
22:08 rue_more I havn't used up mine yet, but I'm not convinced I havea lifetime supply
22:08 Tom_itx i got probably 200lbs of it
22:08 Tom_itx if you want it all
22:08 rue_more :/ I prolly only have 75
22:08 rue_more I should see about price for a crate
22:08 Tom_itx i _had_ 2 pickups full at one point
22:08 rue_more {:[
22:09 Tom_itx and alot of that was full unopened sheets
22:09 rue_more that might be enought o keep me assured
22:09 Tom_itx 3 x 4' sheet
22:09 rue_more I have two 4'x4' sheets
22:09 rue_more carefully tucked away as to not get scratched
22:10 Tom_itx my full sheets are stuck behind the furnace
22:10 spiteball I wanted to use it to open/close a door
22:11 rue_more psssssstch
22:11 spiteball not like a house door
22:11 spiteball more like a flap
22:11 rue_more like a door on the Heart of Gold?
22:11 rue_more 'aaaaahhhhhhhh'
22:11 rue_more a house door is a flap
22:12 rue_more with a latch
22:12 rue_more and optional windows/cats
22:13 spiteball my cat disapproves of you calling it optional
23:19 rue_more well when i made the z80 motherboard I chose my eeprom chip well, it turns out the programming protocol on about every toher chip is really ugly in comparison
23:19 rue_more most all of them require you to write a whole selctor and will start programming it on a timeout basis
23:20 rue_more aka, 300us of no access will start a programming cycle
23:26 GargantuaSauce that sounds dangerous
23:45 maestrobones Would you guys recommend AutoCad for making 3d printed parts of a robot?
23:49 Triffid_Hunter maestrobones: I recommend openscad
23:50 maestrobones Triffid_Hunter: Why is that?
23:50 Triffid_Hunter maestrobones: https://www.youtube.com/watch?v=C8OcIe47-4s and https://www.youtube.com/watch?v=0l3Z7WVfa9c and https://www.youtube.com/watch?v=0m7qMmTXLNo
23:51 maestrobones Triffid_Hunter: Why is it better for robotics?
23:51 Triffid_Hunter maestrobones: it's all code, so trivially simple to make shapes parametric, or have things sized/positioned according to mathematical formulae
23:52 maestrobones Ah
23:57 rue_more or just make robots out of things available, like this one made of 3" pvc
