00:24 rue_house on a nice warm rug on the floor
00:25 rue_house in a big open space
00:28 rue_house I have some analog devices analog selector chips, maybe I should have used them
00:28 rue_house this project dosn't have enough blinky lights, I should add some bar displays, 4017 and 3914 to it
00:30 tsmeow-afk gives rue a saucer of warm
00:30 e_house laps it up while thinking about remembering to order more 16 pin soc
00:31 e_house stops to wonder why he's lapping up
00:31 rue_house oh yea, I have arms
00:31 katsmeow-afk it's a custom
00:31 e_house picks up the dish and keeps drin
00:36 rue_house whats the non-fiberglass pcb called?
00:38 katsmeow-afk bakelite?
00:39 katsmeow-afk don't ask me why i am studying drive r:\ at Center for Nuclear Waste Regulatory Analyses
00:39 katsmeow-afk oops, wrong room
00:39 rue_house na, the compressed paper ones
00:39 rue_house there's a name I'm sure
00:40 rue_house hahahah the electronics store I go to sells "arduino offset headers"
00:40 rue_house the arduino had a header located .05" out from the .1" grid the rest use
00:41 katsmeow-afk wierd
00:41 orlok like you would ot notice and correct that "bug"
00:41 katsmeow-afk needle nose pliers should fix that
00:42 orlok iirc the comment was "we had made 1000 boards and by then it was too late"
00:42 rue_house http://www.leeselectronic.com/
00:42 rue_house good prices, but shy on images
00:42 rue_house its prettymuch a walkin store
00:43 rue_house I knew lee, when I was doing the repair shop he nick named me "wednesday guy" cause wednesday was parts day
00:47 rue_house http://upload.wikimedia.org/wikipedia/commons/thumb/c/c3/Cordwoodcircuit.agr.jpg/500px-Cordwoodcircuit.agr.jpg
00:47 rue_house how do you design a circuit like that?
00:47 ace4016 you dont
00:47 rue_house 2 layers but on acid?
00:47 katsmeow-afk those were once common
00:48 orlok wow, a resistor with hand painted colour bands?
00:48 rue_house repair would often not be an option I take it
00:48 katsmeow-afk sure, just cut out all that was in the way
00:49 orlok i discovered a non-functional car alarm in the subaru on the weekend
00:49 rue_house by accidently fixing it?
00:49 orlok no wonder i was having problems with the wiring
00:50 orlok i had bought a service manual, couldent see a pile of the wires i was seeing in it
00:50 orlok it was still half sliced in, twist+taped
00:50 orlok including to the spak control module things :-\
00:50 rue_house just like the booklet says to I'm sure
00:50 orlok 3 wires twisted together and taped over sitting on top of the engine
00:50 rue_house paging thru a booklet on how ot instsall a remote start system really scared me
00:51 katsmeow-afk i have a psu pcb outside, got to clean the mice off it, the filter cap and diodes are all connected to the pcb with Fahnstock clips
00:51 katsmeow-afk and it was a production pcb too, not a one-off
00:51 rue_house becuse I know that it went out to thousands of people, some of which, followed those instructions
00:51 rue_house fahnstock?
00:52 tsmeow-afk
00:52 rue_house what that?
00:52 katsmeow-afk oh
00:52 katsmeow-afk those useto be real common also
00:52 katsmeow-afk http://en.wikipedia.org/wiki/Fahnestock_clip
00:53 rue_house I'm buying jfets today, cause I never had any as a kid to make those circuits with in "getting started in electronics"
00:53 rue_house hahaha those!
00:53 rue_house oh god, really?
00:53 katsmeow-afk really
00:54 katsmeow-afk i built my first radio with those too
00:54 rue_house I was gonna make a comment about radio tube circuits built on planks
00:54 rue_house I should build some of the stuff from that book too
00:55 rue_house I dont need 45V batteries, I have switching power supplies
00:55 rue_house thye must have had an old engineer design the supplies
00:55 rue_house I'd like a pic of that one if you have the chance
00:56 rue_house http://en.wikipedia.org/wiki/File:Fahnestock_clip_designs.png
00:56 rue_house figure 1 is the only ones I'v ever seen
00:57 katsmeow-afk when i moved here, one grocery store still sold 22v, 45v, and 96v batteries
00:57 rue_house :) I dont know what that says about which
00:58 home katsmeow-afk: dafuq
00:58 home where do you guys get these batteries?
00:58 rue_house lost as always
00:58 rue_house 45V is a B battery?
00:58 rue_house or E1 ?
00:59 rue_house damned if I remember
00:59 katsmeow-afk i don't remember
00:59 e_house looks for the
01:00 katsmeow-afk the 22v was sometimes used to pull grid bias below gnd, iirc
01:00 katsmeow-afk 96v was alwats plate supply
01:01 katsmeow-afk 45v is tetrode bias? rf triode plates? iirc there were no pentodes then
01:04 rue_house I cant find my tube book
01:04 rue_house it was a good one
01:05 rue_house it might be out int eh shop
01:05 rue_house I should teach the robotics kid tube basics, make a small amp
01:06 katsmeow-afk usetobe, you could buy kits to make your own vac tubes
01:06 rue_house ? cool
01:06 rue_house gnight
01:06 katsmeow-afk they'd sell you the base with pins, and some glass tubing, and assorted internal parts
01:06 katsmeow-afk oh
01:06 katsmeow-afk gnite, sorry
01:17 rue_bed ah glass then, wow
01:18 katsmeow-afk ?
02:00 rue_bed I'd have expected somehting soldered or something
02:00 rue_bed like to see a pic of one of those kits, w/instructions
02:01 rue_bed they must have used one neat tricks
02:01 rue_bed some neat tricks
02:01 rue_bed iirc all the connections in a tube are spot weleded on account of the heat
03:17 katsmeow-afk http://stemak.org/sites/default/files/DIY-Electron-Accelerator-A-Cathode-Ray-Tube-in-a-.pdf
03:56 katsmeow-afk rue, see section http://en.wikipedia.org/wiki/Vacuum_tube#External_links , item Video of amateur radio operator making his own vacuum tube triodes
05:35 katsmeow-afk http://www.neoseeker.com/Articles/Hardware/Reviews/aopenax4btube/
07:21 theBear OH MY A-GOD !!!! i can't believe, the, those fools !
07:22 theBear then again, at least a mobo pcb is nice and thick and solid, and they probly only run 12v plates or something, and you stupid reviewer ! it's a dual triode tube, of course it's "a class"
08:53 rue_house I know there are people who have done it since, the idea of a kit was intersting
08:56 rue_house http://stemak.org/sites/default/files/DIY-Electron-Accelerator-A-Cathode-Ray-Tube-in-a-.pdf
08:56 rue_house ^^ I can feel the x-rays from here!
10:13 katsmeow-afk i dunno bear, a dual triode can be AB1 or AB2 as well, or paralleled C
12:08 theBear katsmeow-afk, in stereo ?
12:09 GuShH theBear: have you watched this new series called Black Dynamite?
12:10 GuShH It's animated
12:10 theBear no, but i LOVE the movie
12:10 GuShH There's a movie? about the same thing?
12:10 GuShH Anyway, quite funny I bet you'll enjoy it
12:20 theBear i dunno about the same thing, it's a kung-fu expert black shaft-style dude mostly
12:21 theBear complete with 'classic' disco style soundtrack, and i mean band-disco, not that drum machine stuff
12:53 sonu i want to build fire proof robot for robot war , which material would u recommend it to me ?
12:53 sonu please do reply !
12:58 sonu help me please
13:01 chris_99 how about metal?
13:02 sonu which metal ? thats what m asking
13:04 chris_99 http://www.engineeringtoolbox.com/melting-temperature-metals-d_860.html
13:10 sonu thats not quite helpful to be honest
13:12 sonu http://en.wikibooks.org/wiki/Robotics/Design_Basics/Building_Materials
13:14 theBear it's infinitely more helpful than the link you just pasted... start with metals that won't melt at your desired temp, narrow by affordability and potential physical suitability, if that cancels out too many options then think about cladding a 'chassis' with the protective material/metal
13:15 GuShH heh
13:16 GuShH just because a metal won't melt at a certain temp, doesn't mean everything else won't, heat will spread onto everything. you need insulation boy!
13:16 GuShH sonu: sounds like you are way over your head on this one.
13:16 GuShH what's your budget?
13:17 theBear yeah, thermal inertia AND resistance will be factors ....
13:17 GuShH I ask because there are fancy materials out there... but that means $$$
13:19 GuShH Otherwise two layers of cheap ass rolled steel and polyurethane foam in between, or one steel, foam, alu. Always making sure the foam is not exposed to open flames, of course!
13:20 GuShH If you are serious about winning, you could try having a fake alu shell on top, that is thin enough to rip off easily. This means the attacker will most likely get jammed up with it.
13:20 theBear oooh ! fun size spike-chains
13:20 GuShH That calls for hidden wheels.
13:20 ShH ponders chainsaws on the r
13:21 GuShH wait, we are like several 1000s over-budget now
13:21 theBear if it robot-wars style rules i think they'd have to be electric... still, modern electric motors are kinda kickarse
13:21 GuShH pffft
13:21 GuShH 2 stroke would be so much fun
13:21 GuShH sure, you could have a ball of flames if the tank is punctured, so what? that's the whole point.
13:22 theBear hehe good call
13:22 theBear we should start our own league
13:23 GuShH these things cost money to build! a lot of money!
13:23 GuShH better get redbull involved.
13:24 theBear oooh ! 12 cylinder rotary supercharged robot ?
13:24 theBear with a crazy old foreign pilot with an amazing moustache ?
13:25 GuShH o.o
13:25 GuShH no, germans are weird.
13:26 theBear fine, you can have a non-german pilot YOUR robot
13:27 theBear hehe, that dude rocked, anyway, gnight :)
17:37 katsmeow-afk whadda mean by "morgue-rate options"?
19:40 katsmeow-afk i accidently saw some of the tv show "dancing with the stars", and i can't believe humans would watch that on purpose
19:41 keepisho1 Welcome to 1984
19:46 katsmeow-afk it was disgusting: the woman(?) was acting like a spastic robot with positional feedback control issues, and the man acted like he was trying to hold her(?) upright without getting hit
19:47 katsmeow-afk both had really bad taste in clothing, some of which was too tight, missing, or too loose
19:48 katsmeow-afk the women in the background of one shot looked totally embarrassed to be seen in what they were wearing
19:55 GuShH katsmeow-afk: that's what your country loves to watch
19:56 katsmeow-afk all the more important i leave it
19:56 Triffid_Hunter katsmeow-afk: http://youtu.be/2HiuCaaQhxg
19:57 katsmeow-afk it didn't play, and i think i am happy it didn't
20:03 ace4016 lol
20:03 ace4016 don't like revealing clothing? :P
20:04 ace4016 although, their cosutmes are typically tacky...
20:04 ace4016 it's not really an american thing to have such tacky dance clothing
20:05 katsmeow-afk the tackyness of the clothng is not even pertinent to the alledged "dancing"
20:05 katsmeow-afk if it was somehow a dance about bad clothing, ok, but it isn't
20:06 ace4016 uncoordinated starts learning to dance from professionals has been popular for a few years :P
20:06 ace4016 it's where their career goes to die
20:06 ace4016 also, the dances are also typically not american
20:30 rue_shop3 its interesting how much less work there is in a 3 bit bus than there is in an 8 bit
20:44 rue_shop3 heh, I screwed up the chip rows, there isn't room for a chip in the middle
20:45 keepisho1 lame
20:47 rue_shop3 anyhow, to the best of my ability to tell, the controller board is done
20:47 rue_shop3 now I have to make all the interconnect cables
20:53 rue_shop3 1U is kinda tight
20:56 keepisho1 Bit slim yeah
21:16 vageSimian idly picks at fur infesta
21:20 SavageSimian anybody here ever order custom spur gears from china?
21:22 rue_shop3 did you say reprap?
21:22 SavageSimian uh, no. was just wondering on a source of parts. i'd like to get some precision spur and pinion gears for an XY table.
21:23 Tom_itx rotary?
21:24 Tom_itx rack and pinion?
21:24 Tom_itx why would you do it that way?
21:24 SavageSimian my table has M3x.5 screws. i'd like to see if i could get the precision into the micrometer range.
21:24 SavageSimian rotary
21:24 Tom_itx linear stepper
21:24 SavageSimian y
21:25 SavageSimian 7.5º steps
21:25 Tom_itx have you looked at them?
21:25 Tom_itx linear slides
21:26 Tom_itx or gear reduce your current setup
21:26 SavageSimian i've got other motors that'll do 1.8º but the 7.5's fit the mounts. i'd prefer not to have to remake em. don't have a decent mill or machine tools for the job.
21:27 Tom_itx 7.5 is pretty coarse
21:28 SavageSimian yea i know. i wouldn't mind at all switching to the 1.8's but i don't have torque specs on em and i'd have to come up with better gears anyway.
21:28 Tom_itx what is this on?
21:28 Tom_itx http://www.kelinginc.net/NEMA23Motor.html
21:29 Tom_itx there are steppers with specs
21:29 SavageSimian XY compound table. it's mounted on a mini-drill press. currently i'm using it for working with lasers and microscopes.
21:29 SavageSimian yea. i've got lots of loose motors. seems like a waste to go buy more.
21:30 Tom_itx figure out the specs on them then
21:30 SavageSimian if it comes down to it i'll just measure torque on em.
21:30 Tom_itx or just test em
21:30 SavageSimian yep. that's probably what's goin to happen.
21:31 SavageSimian do you know of a way to measure max power without frying the motors?
21:35 Triffid_Hunter SavageSimian: start at low current, ramp up slowly.. stop when the motors are at 45c or so
21:35 SavageSimian would maximum holding torque on a stepper require max power?
21:36 SavageSimian if so maybe i could just find a holding torque and measure the input power.
21:36 Triffid_Hunter SavageSimian: torque is proportional to current, so is heat
21:37 Triffid_Hunter SavageSimian: voltage is proportional to speed, plus whatever's required to push the current through the winding resistance
21:37 SavageSimian i've got a thermal sensor but i'm not particuarly confident in it's accuracy.
21:37 Triffid_Hunter SavageSimian: the motors are damaged by overtemperature, so the max current really depends on its winding resistance and ability to dissipate heat
21:38 SavageSimian ah. so watching the temp is probably the best way to measure it without (pun intended) frying it?
21:39 Triffid_Hunter yep
21:39 SavageSimian i thought motor damage was due to breakdown in the dielectric of the wire insulation.
21:41 ace4016 depends on the motor
21:41 Triffid_Hunter SavageSimian: you can damage them that way too, but they're usually rated to 500VDC
21:41 Triffid_Hunter SavageSimian: so I suspect you'll fry them with overcurrent long before overvoltage ;)
21:42 SavageSimian ah. didn't know that. i'm probably not gonna put 500 vdc thru em - even tho that might be an interesting experiment... :p
21:42 SavageSimian ... i do have a flyback transformer around here someplace...
21:43 SavageSimian maybe i can get it to levitate before it vaporizes.
21:48 keepisho1 Anyone have a favorite arduino?
21:48 Triffid_Hunter keepisho1: hong kong mega 2560 clones
21:49 Triffid_Hunter keepisho1: also, arduino libraries suck, use them for learning but then discover how to program the hardware in raw C :)
21:50 keepisho1 I'm coming from an RCX background.
21:50 keepisho1 I'd really love to use bash to code it though. heh
21:50 keepisho1 C is not a problem though.
21:50 SavageSimian just out of curiousity, what do arduino's have that PIC's don't?
21:51 keepisho1 breakout pins
21:51 keepisho1 and an ftdi chip
21:51 Triffid_Hunter SavageSimian: 1 instruction per clock, 32 registers, built-in usb<->serial and voltage regulator, better peripherals esp timers, a solid open source toolchain
21:51 SavageSimian lots of pics have on-chip USB support and you don't need a demo board to run em.
21:52 keepisho1 I just need something I can drive a few l293d chips with.
21:52 Triffid_Hunter SavageSimian: get a 32u4 or similar if you want on-chip usb.. the mega 2560s use an 8u2 instead of an ftdi chip now, so you can reflash them to be HID or MSC or whatever
21:52 SavageSimian you can drive 293's with anything.
21:52 keepisho1 My parallel port plan kinda failed.
21:52 keepisho1 I'm 10 years too late. :(
21:52 Triffid_Hunter keepisho1: little uno would work fine probably
21:52 keepisho1 I was looking at a nano
21:53 Triffid_Hunter SavageSimian: I'm leaving 8bit behind though, getting into arm cortex-m3
21:54 keepishop What I *should* be doing is stripping down linux boxes to do this junk.
21:54 keepishop Digital output is a problem though.
21:54 SavageSimian yea. i don't need anything bigger the 8 or 16 bit in a microcontroller. only thing i use em for is motor control and sensors. haven't run into anything that needs more uumph then that.
21:54 keepishop I really would rather use generic linux tools. :/
21:55 keepishop I can make a linux box boot in 5 seconds easy enough, so pics seem useless.
21:55 SavageSimian if i want some real computing power i just hook em up to a PC.
21:55 keepishop But with no gpio ports it's useless.
21:55 Triffid_Hunter keepishop: linux isn't great at hard realtime, even with RT kernel.. there's plenty of arm linux things out with GPIO though, see RPi, cubieboard, beaglebone, etc
21:56 Triffid_Hunter keepishop: but if I'm generating PWM pulse trains, I'm gonna use a microcontroller
21:56 keepishop acceptable response time for me is 100ms
21:56 keepishop I don't care about realtime for now.
21:57 keepishop I'm just trying to dip my toes in the water without paying a ton.
21:57 Triffid_Hunter keepishop: ah, well small linux box will work fine then
21:57 keepishop I have an eee900 I want to use.
21:57 SavageSimian how ya gonna shoot flies out of the air with a 100ms response time?
21:57 keepishop No. Shooting my cat.
21:57 keepishop Should work fine. It's stationary 90% of the time.
21:57 Triffid_Hunter I'm coming from reprap-land where we need microsecond precision timing signals at frequencies up to 40khz or more, and high level chips just don't have those capabilities
21:58 SavageSimian ah. ok, got it. but i doubt it's gonna stay stationary if yer shooting at it...
21:58 keepishop Triffid_Hunter: Then I will take your obsolete equipment happily.
21:58 SavageSimian Triffid_Hunter why do you need timing that fast for a 3d printer?
21:58 keepishop brb
21:59 ace4016 hehe, shooting flies out the sky? reminds me of a ted talk: http://www.ted.com/talks/nathan_myhrvold_could_this_laser_zap_malaria.html
22:01 SavageSimian heh. well if yer gonna shoot malaria with it you might want to suck the blood out first. ppl probably won't be all that happy to be zapped with a laser beam.
22:01 rue_shop3 Triffid_Hunter, those non-high level chips are supposed to be avrs
22:01 rue_shop3 smart perphials
22:01 rue_shop3 take care of their own timing
22:02 Tom_itx Triffid_Hunter you should take a look at the mesa boards
22:02 Tom_itx 50Mhz fpga
22:02 Tom_itx offloading the bulk of the work
22:02 rue_shop3 well, I reverse engineered the keyboard...
22:03 rue_shop3 the circuit boards are made and mounted
22:03 rue_shop3 no idea what to do with the power switch
22:03 rue_shop3 for now I suppose I'll just leave it disconnected
22:13 Triffid_Hunter SavageSimian: generating step pulses.. if there's too much jitter in the pulse train, the motors lose steps
22:13 Triffid_Hunter SavageSimian: http://youtu.be/ndOzDB44NT8 <-- 80 steps per mm in X and Y, and those speeds are fairly standard by modern reprap standards
22:14 e_house knocks on
22:14 rue_house katsmeow-afk,
22:14 Tom_itx Triffid_Hunter i put a mesa card on my mill and along with the gecko drivers feel it was one of the best things i ever did for it
22:15 Tom_itx it's microstepping 40000 steps / inch at 80-90+ ipm which is pretty good for a small mill
22:15 rue_house !assist projects/audioswitch
22:15 tobbor Possibly http://eds.dyndns.org/~ircjunk/projects/audioswitch
22:15 rue_house http://eds.dyndns.org/~ircjunk/projects/audioswitch/p1040621.jpg
22:15 rue_house all air, as usual
22:15 katsmeow-afk "Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius - and a lot of courage - to move in the opposite direction." Albert Einstein
22:15 rue_house its cool that the 1/4" spades fit on the adapter plugs
22:16 rue_house its uncool that I only have 2
22:16 SavageSimian Triffid_Hunter that looks like a really nice printer but the frankly the part looks nothing like a girls sock...
22:16 Tom_itx Triffid_Hunter, maybe i'm mistaken.. i thought you were looking for something better than what you had
22:17 rue_house ^^^ who can find the peice of 4" PVC pipe?
22:17 SavageSimian Triffid_Hunter i assume you're using a 24v supply to drive your motors? your printer looks like it moves a lot faster then most of the 3d printers i've seen.
22:17 Tom_itx that would help
22:17 Tom_itx on my mill i'm running them at 50v
22:18 SavageSimian does your mill use belts for the drive system?
22:18 Tom_itx screws
22:18 rue_house kat, its gonna take me ages to find and connect shielded wire between the connectors and the switches
22:18 Tom_itx 20 tpi lead screws
22:18 SavageSimian full sized mill?
22:18 Tom_itx so 80-90 ipm is pretty respectable i think
22:18 Tom_itx no
22:18 Tom_itx a smallone
22:19 katsmeow-afk 1) not that many peoples use shields for so many cables in a metal box B) move the pcb closer to the connectors so they solder directly with no wires
22:19 Tom_itx i know someone with a plasma cutter getting around 200 ipm with a very similar setup
22:20 SavageSimian i was thinking about trying ball screws. heard they were fast and accurate.
22:20 katsmeow-afk if you really wanna run separate gnd with each signal wire, peel off 2-wire pairs off some ribbon cable
22:20 Tom_itx same drivers similar steppers
22:20 rue_house na I hate pcb's that cant be removed without looking like a nuclear mutated spider
22:20 Tom_itx ball screws are good
22:20 rue_house its a plastic box
22:20 katsmeow-afk which remins me the two 10ft ball screw rods still at recycler
22:21 rue_house but that dosn't mean a little tinfoil and some creativity couldn't shield it
22:21 rue_house I want something between those smps and the audio circuit
22:22 Tom_itx why?
22:22 Tom_itx you think it's that noisy?
22:22 katsmeow-afk ah
22:23 SavageSimian Triffid_Hunter do you have a page up on your printer build? i'd be interested in taking a look at it.
22:26 rue_house prolly
22:26 rue_house its two cheap cell chargers
22:28 rue_house kat, I found out I dont really need ~5A transistors, I seem to have bought a rail of 5A fet half bridges
22:32 katsmeow-afk i said you needed 5amp transistors?
22:39 rue_house no
22:39 rue_house I was choosing the high current transistors off ebay as $1 items
22:39 rue_house I hope someone lists some intersting chips cause I think I'v bought just about everything else
22:40 Triffid_Hunter SavageSimian: nope, 12v is quite sufficient
22:40 katsmeow-afk oh, i was choosing 100's of lower current devices you could parallel to make 5amp, or 10amp, or 50amp, at lower prices than bying 5amp,or 10amp or 50amp devices
22:41 Triffid_Hunter SavageSimian: got a blog at wooden-mendel.blogspot.com but I don't post there much.. got pictures up at https://picasaweb.google.com/114006544968779005866/Mendel
22:41 SavageSimian Triffid_Hunter ty. i'll check it out.
22:42 SavageSimian Triffid_Hunter did you copy someone else's build or is this all your design?
22:43 Triffid_Hunter SavageSimian: it's a mashup really.. started off as a sells mendel, then prusa released his halfway through my build so I adapted what I had to his much simpler design.. then ended up remodelling a bunch of the parts myself
22:43 SavageSimian ah. ok. i was thinking about doing a prusa build. haven't gotten around to it yet.
22:44 SavageSimian have you tried making gears on your printer yet? i'm wondering at the quality...
22:45 orlok he's made unicorns!

22:45 SavageSimian unicorn gears? those are the hardest kind to make.
22:45 Triffid_Hunter SavageSimian: https://picasaweb.google.com/lh/photo/2qP3SvrwWGQ88wNhhMrmCdMTjNZETYmyPJy0liipFm0 <-- here's a nice print with a ruler for scale :)
22:46 SavageSimian that is a really nice finish on the parts. is that straight off the printer or post processing?
22:46 Triffid_Hunter SavageSimian: straight off the bed like that, https://picasaweb.google.com/lh/photo/ba-O-l8e1LYTKt-OYy4bWdMTjNZETYmyPJy0liipFm0 is a mid-print shot
22:47 SavageSimian wow. i'm impressed. nice work. now i want one... :p
22:47 Triffid_Hunter SavageSimian: https://picasaweb.google.com/lh/photo/-pajweQDBx6LfDBeyILMO9MTjNZETYmyPJy0liipFm0 <-- stuff like this is pretty easy too.. those are M3x20 for scale
22:47 Triffid_Hunter or maybe M3x15, don't remember

22:49 SavageSimian got any favorite build sites?
