00:04 any27357311 looks like a broader soa curve than the tip36
00:05 any27357311 4a@40v on the IRF, 1a@40v on the tip
00:06 any27357311 tip14x = 2a@40v
00:08 any27357311 qty/$ break is qty50 they go under $1 each
00:11 rue_shop3 just a sec
00:13 rue_shop3 still, they are much better relays than I expcted
00:13 any27357311 price?
00:16 y27357311 ponders 80
00:21 any27357311 dated 1984 , says new, never used
00:31 rue_shop3 hmm
00:33 any27357311 you think someone held onto them, waiting for the price to go up, for 30 years?
00:53 rue_shop3 na
00:53 rue_shop3 they just kept the price higher than what people were willing to pay for them
00:57 any27357311 i don't remember the price, i remember they all seem to be 8Mhz parts
00:59 any27357311 11us for add/subtract
01:03 any27357311 integer-to-memory store instructon takes 100 clocks
01:03 any27357311 a bcd store may take 310 clocks
01:04 rue_shop3 I like lookup tables
01:05 any27357311 we all do, but a 32bit by 32bit multiply look up is *HUGE*
01:10 rue_shop3 why cant we just use 8 bits?
01:11 any27357311 can, even diaseychain the lookups, but that starts getting slow too
01:12 any27357311 for an 8x8 math, you need 10 bits out, so figure a 64kx16 chip (i got em)
01:12 any27357311 for 16x16, you need 4 of them, feeding into a adder, but the adder has serial carry
01:12 rue_shop3 I seem to be low on mental energy
01:13 rue_shop3 thinking clearly is more and more of a challange
01:13 rue_shop3 I think I have a brain problem
01:14 any27357311 2^16 * 2^16-1 = 4,294,901,760
01:14 any27357311 32bits
01:14 any27357311 and if it must do a carry from bit 8 on up, that's 24 carries
01:15 any27357311 err,
01:15 any27357311 that's 48ns for carries
01:16 any27357311 still beats the heck ot of an 8087, but it's also dropping the speed down to 2 mips
01:16 any27357311 and i don't have a way to beat it :-(
01:40 any27357311 "empty" isn't all that easy to say correctly, it's not said like "m-t"
02:40 rue_bed I'm thinking I should keep the kats in while the little birds learn to fly
02:42 any27357311 yeas
02:51 any27357311 they should be flying in a day or two, or something else will eat them
03:11 any27357311 almost every time i put down something, my wrist tweaks
03:30 any27357311 heh, 1/8 braided air muscle
03:33 any27357311 assorted colors, 10ft long, 1/4 muscle : $1.98 usd $2.55 s&h
03:35 any27357311 1/2 braid 10ft $3.95
03:35 any27357311 1" braid 5ft $3.75
04:12 any27357311 The DSRC is responsible for operation and maintenance of supercomputing systems and the transfer of technical knowledge to DOD research projects. It typically operates two or more supercomputers on an average four-year life cycle.
04:12 any27357311 and then they throw it away
04:12 any27357311 The DSRC�s computing resources include 1.8 peak PFLOPS of computing capability
04:13 any27357311 which will be inadequate in 4 years
04:14 any27357311 32GB dedicated memory per node, and 7200TB disk storage; ... 24GB of dedicated memory per node, and 721TB of disk storage; ... 64GB dedicated memory per node, and 140.4TB disk storage; and 15PB of local archival tape storage.
04:15 any27357311 10,000 square feet of raised floor computing facilities.
04:15 any27357311 4 megawatt Un-interruptible Power System (UPS), which includes an on-line 2 megawatt battery system and an on-line 2 megawatt flywheel system
04:29 y27357311 grabs a usb extension cable, and hides the recieving end in a big ole battery jumper cable clamp, just so the Saturday Kids can tell their parents that rue uses battery cables to access his thumbdr
09:14 rue_bed how much does a baby chick bird eat?
09:15 rue_bed its calling again...

22:49 any45146283 "Pay a maximum of $1.98 shipping on all eligible items from ichoseilove."
22:50 any45146283 TIL that Post-it makes a cheese-colored note, but it doesn't taste like cheese
22:50 any45146283 wth, there's a tv series called Extant
22:51 any45146283 there's a robot kid on it
22:53 any45146283 i am talking to myself online, same as i do irl all day, and most of the nite
22:59 any45146283 fwiw , HomeDepot will now provide 10-paks of the coroplast, they call it "plastic cardboard" : http://www.homedepot.com/p/Unbranded-48-in-x-96-in-x-157-in-White-Corrugated-Plastic-Cardboard-10-PACK-WC4896-10/202489118
23:00 any45146283 single sheets will cost you another $2 per sheet
23:00 any45146283 i haven't see the packs
23:05 rue_shop3 ah the mighty fabricator is back
23:05 rue_shop3 you awake?
23:06 rue_shop3 drat
23:16 rue_shop3 I need to know how to makea mark exactlyon the other side of a pipe so i can mark holes to drilll thru
23:17 any45146283 oh
23:17 any45146283 indexing lathe
23:18 rue_shop3 arg, need ot make an indexer for the lathe
23:18 any45146283 chuck the pipe, turn it, nick a circle around it, stop lathe, mark groove with tool post, rotate head 180, mark groove with toolpost again
23:19 any45146283 should be extremely accurate
23:19 any45146283 extreeeeeeeeeeeeeeeeeeeeeeeeeeeeeemely
23:20 any45146283 you can make the circle around it if you set the pipe in a narrow channel or angle, butt it against a steel wall, use visegrips to cmalp a scribe against it, then just turn the pipe
23:21 any45146283 wall needs to be vertical
23:21 any45146283 pipe needs to be square to it
23:22 any45146283 it's how i cut all those rollers outa tubing, and they are all witin .010 in all respects
23:22 any45146283 the marking was accurate, the cutting wandered a lil (no lathe)
23:24 any45146283 instant 180: chain pipe visegrips, pipe extended off the table, but laying in a upturned angle so it cannot move
23:24 any45146283 let visegrip hang, measure horizontal to nearest wall, rotate visegrips upright, measure horizontal to nearest wall
23:24 any45146283 that's 180
23:25 any45146283 wall must be vertical
23:25 any45146283 measuer to exactly the same place on the visegrip handle, like the center of the tightening screw, you get the idea
23:35 any45146283 hello
23:39 any45146283 i said something soo stupid, you left the room?
23:55 rue_shop3 I got it printing again, I'm back
23:56 rue_shop3 ooo I should make a chaingrip like thing for doing that
23:57 any45146283 umm, yea
23:57 rue_shop3 I was distracted, I'm printing http://www.thingiverse.com/thing:892654
23:57 any45146283 they get a grip on other shapes too
23:58 rue_shop3 I should start drinking tea, my eyelids are getting heavy
23:58 rue_shop3 I'm also working on antoher mecha finger
23:58 any45146283 umm, is that for a halloween costume?
23:59 rue_shop3 one of the guys who comes by the shop was playing with the wirefeed and we got it working
23:59 rue_shop3 I think I can turn it into a motion capture device, I need to be holding it to know
