00:11 mbass looks pe
00:12 dumbass so there's 4 modules of floating isolated chargers, leaving 2 slots in the rack
00:13 dumbass there's no way i can put the big caps i got into one slot, and there's no good reason to merge the fat grounded charger and the DC-AC convertor into one 2-wide module
00:14 dumbass 350v is actually too small to rectify 240vac into, and i'd need 3 of the 75v caps to filter 120vac
00:41 rue_shop3 hmm
00:43 dumbass ok, i found a pair of 1800u@450v caps i can put across the battery bank, but the pair take up almost half the space in a single plugin, and they are ancient caps
00:45 dumbass or i can put in 8 new 470u@450v caps that take up half as much room
00:46 dumbass welllp, solve that problem, i spose, no point collectng these things if i don't use them in the best way possible
01:17 dumbass pile of 20N60s too
02:14 dumbass ...
02:19 dumbass shouldn't there be hordes of humans awake and feverously programming their robots to take over the world? where are they?
02:19 dumbass i don't mean asholes like GuShH_, who i have on ignore
02:28 mbass growels at heat losses : fwb rectifier operating across the 240vac line throws 30watts at 20
02:30 dumbass 40TPS08 ?
02:33 dumbass 40amp 800v scr
02:35 dumbass soft start circuit ! no need to put 1000's of ufd right on the 240v line like a dead short :-)
02:36 dumbass only way i'm gonna get these off the pcb is with a paint stripper gun
02:42 dumbass it is always going to be like this, isn't it?
10:12 Tom_itx this or worse
10:18 dumbass-afk For years astronomers have believed that the coldest place in the universe is a massive gas cloud 5,000 light-years from Earth called the Boomerang Nebula, where the temperature hovers at around -458�F, just a whisker above absolute zero.
10:18 dumbass-afk The coldest place in the universe is actually in a small city directly east of Vancouver called Burnaby. Burnaby is the headquarters of a computer firm called D-Wave.
10:18 dumbass-afk Its flagship product, the D-Wave Two, of which there are five in existence, is a black box 10 ft. high. Inside is a cylindrical cooling apparatus containing a niobium computer chip that's been chilled to -459.6�F, almost 2� colder than the Boomerang Nebula.
10:20 mbass-afk thought you'd want to
10:29 dumbass-afk February 3, 2014 ; The International Space Station will soon be the coldest place in the known universe. A new instrument that will be sent to the ISS, called the Cold Atom Lab, will reach temperatures as low as 100 picokelvin � 100 trillionths of a degree above absolute zero.
10:30 Tom_itx are they sure it's not just 99?
10:30 dumbass-afk so basically, layer some quantum puters in space, below -460f, and call that the new cloud
10:31 dumbass-afk NASA says the Cold Atom Lab, which will launch to the International Space Station in 2016, will be the coldest place in the known universe. To be fair, one group hit 100 picokelvin way back in 1999.
10:32 dumbass-afk The quantum effects won�t be �visible to the unaided eye� because if you shine light on the experiment, you will raise the temperature too much. The system will have to be observed indirectly using instruments.
10:34 mbass-afk smells like 2-part epoxy again, but the peptobismol caps turned out really
11:08 dumbass-afk for most caps, i drive a screw thru the childproof caps, locking the two together, but pepto will eat at even stainless steel screws
11:09 dumbass-afk so, the two parts of the pepto caps will come apart with application of a thin small flat blade screwdriver inserted tween them
11:10 dumbass-afk you then mix the 2-part, smear it on the inside of the white cap where the threads are supposed to be, but you don't want it to flow down the cap and puddle in the bottom as it sits on your desk
11:11 dumbass-afk then press in the clear cap, it will stop ~4mm short of going all the way in, so flip it over and mash the white down over the clear, right down to the tabletop
11:12 dumbass-afk pick up, and ease the clear cap down another mm or 2, it may click as it eases below the rim of the outer white cap
11:12 dumbass-afk clean it up a lil with tpaper if you like, or not, you can peel excess epoxy later when it's set up
11:13 dumbass-afk don't bottom the clear cap down inside the white cap, it won't bottom unless you force it, so don't
11:14 dumbass-afk let it sit some hours before use, don't torque down on it for a day, even if it's "5 minute" epoxy
11:14 dumbass-afk presto, it's not child proof any more
11:22 dumbass-afk i also think i found a way to stop some of the expandofoaminsulationinacan from setting in the tube: duct tape
11:23 dumbass-afk ||=================OOOO <<== then pinch the end closed
11:30 dumbass-afk i can't find a dirt cheap way to get a dozen mips on a post-it size pcb when using ram outside the cpu, the 15Mhz 65C02s at 15Mhz will crank out ~6mips , the 8Mhz AT90S4414 avr will slow to ~2mips with external ram
11:30 dumbass-afk and the 65C02S isn't exactly cheap anyhow
11:33 dumbass-afk one advantage of the 6502 is a 2nd one can be interleaved on the same memory buss, for whatever reason, and two qfp-44 6502 will fit in the space of the original dip-40
11:36 mbass-afk shows Tom the box of 5" long PCI slots, to plug dirt-cheap cpus into, with 184
11:37 dumbass-afk even got gold-plated fingers
11:47 dumbass-afk hmmmmmmmm
11:49 dumbass-afk 3/8 thick, in 12" of 2-wide plugin, is 32 cpu cards 4x5 inches, or 64 of them 2"x5"
11:49 rue_bed 24Mhz 8051 with instruction rate doiubling on?
11:50 rue_bed do they make faster 8051?
11:50 dumbass-afk i dunno, the 80xx series sometimes needs 6 instructon fetches to do anything, yeas?
11:50 e_bed clicks...
11:50 rue_bed the new 8051 dont
11:50 dumbass-afk i don't have any 8051, unless you count the 8Mhz AT90S4414 avr i have
11:50 rue_bed they have a compatability mode that will
11:51 rue_bed will the 8M overclock to 20M?
11:51 rue_bed or even 16
11:51 dumbass-afk no, fixed, which is why it was cheap
11:52 dumbass-afk $2 for a atmel AT89C52-24
11:53 dumbass-afk i have no programming environment for 80xx anyhow
12:01 dumbass-afk hmm, i has some MCM6343TS-15's, i can put 4 on each cpu card to make a 64-bit-wide instruction buss, 256k
12:01 dumbass-afk that could give me 50mips per cpu
12:02 dumbass-afk for 32 cores, that's 1.6Ghz
12:02 dumbass-afk and 1600 mips
12:04 dumbass-afk fwiw, a 2-wide is just wide enough to sit mobo sdram modules across the plugin
12:05 dumbass-afk 32 of them @ 512meg per, is 16Gbytes in my 1,600 mips C-64
12:07 mbass-afk wonders if it can be built for a total cost of $160 (chips, solder, frame, sockets, pcbs), batteries and blinky lites e
12:17 dumbass-afk carp, the MCM6343 is 3.3v, but has ttl ouptup levels, so a high is 2.4v
12:19 dumbass-afk ok, the 74ABT inpus are 2v with 5vcc
12:20 dumbass-afk ok, the 74F inpus are 2v with 5vcc
12:21 dumbass-afk i remember 74LS were stupidly high tho, and C parts are whatever 1/2 vcc is
12:22 dumbass-afk and now that i can connect the C64/Vic20 to the wintel boxes, i can develop and code on the wintel machines, use their monitors and hdds and internet connection on the lil puters
12:24 dumbass-afk holycarp, ebay wants $7.32 + $4 s&h for these chips
12:25 rue_bed which ines?
12:25 rue_bed oines?
12:25 rue_bed lksjflksjfkjdsf
12:25 dumbass-afk MCM6343
12:25 rue_bed the sound chips?
12:25 dumbass-afk static ram , dip-44 256k x 16bit
12:25 rue_bed oh
12:26 dumbass-afk there's some CY62146 256k x 16 at $4 each
12:27 dumbass-afk some CY7C1006 256k x 4bit in Canadia for $1 + $5 s&h
12:29 dumbass-afk prices seems to average $2
12:29 dumbass-afk economy picked up some and they quit giving chips away on ebay :-/
12:30 dumbass-afk well, cept for the 2000 pcs of 74ABT00 for 99 cents
12:31 dumbass-afk well, cept for the 2000 pcs of 74ABT821 for $2.99
12:32 dumbass-afk hmm, tiny2313V-10PU for $1.70 each?
12:34 dumbass-afk micro video cameras for under $10 , 3Mp cameras for under $10
12:38 rue_house yea, the economy is collapsing
12:38 rue_house you know how an engine kicks a few times before it competely runs out of gas
12:51 rue_house I got the 2864 and 28256 chips, this excites me
18:48 mbass-afk is so exhausted and sore that she shut off all the upstairs lites and armed the security system an hour ago, and is now just sitting still and eating pain d
18:48 dumbass-afk and thinking of protocol to usb-boostrap a 6502 with nothing in it's ram and no eproms
18:54 dumbass-afk funny how some beings cannot pronounce some things, kid on tv cannot say "lasagna", my sister couldn't say "movies", the guy on tv couldn't say "Barracuda", and i couldn't say "Hardee's ham and swiss burger"
18:55 dumbass-afk to be fair about the "barracuda" guy, i still have trouble saying "acanthopterygian"
18:57 dumbass-afk sad about the poor kid not being able to order lasagna tho
18:57 dumbass-afk lasagna is serious katfood
19:05 mbass-afk wants some lasgna
19:11 mbass-afk wonders if the local stores would appreciate the stupidity of not delivering food, if i call them and thank them for not selling me a $12 tub of lasagna right
20:41 mbass-afk just noticed, when Lancelot killed Malachai with the king's sword, the next shot of Lancelot shows the sword broken off 2" from the hilt, but no shots of the sword after that show it is br
20:48 dumbass-afk i has the following question:
20:48 dumbass-afk does this:
20:48 dumbass-afk Format: DVD
20:48 dumbass-afk Display Format: Canadian; Extended Unrated Director's Cut
20:48 dumbass-afk mean i can ot cannot play this in the usa ?
20:51 rue_shop3 I think you can play anything but from japan
20:51 dumbass-afk hmm, ok
20:55 mbass-afk wishes she could find some Corydalis yanhusuo that's cheaper than he
20:56 dumbass-afk 100 grams (.22 lbs) ($14.00) dayam
21:03 dumbass-afk http://www.wallmay.net/thumbnails/detail/20120313/science%20text%20cats%20geek%20quantum%20physics%20schrdingers%20cat%20negative%20space%201440x900%20wallpaper_www.wallmay.com_47.jpg
21:09 dumbass-afk "A suspected drunk driver going in the wrong direction on the 60 Freeway in Diamond Bar was traveling faster than 100 mph when she caused an accident" <<== REALLY? an "accident"?? she accidently got in the wrong lanes, accidently put the truck in gear and mashed the gas pedal to the floor?
21:09 dumbass-afk it was a hell of a wreck, but i put fortht hat it was no accident
21:14 dumbass-afk "i stole the gun, i stole the ammo, i went to Fred's house, i loaded the gun, i cocked the hammer, and i slammed the gun down on the table as i held it pointe dt Fred. It then accidently went off and killed him. I am innocent!"
21:15 mbass-afk would like to have alemon merengue pie now, please, since i got no las
21:21 mbass-afk needs a way to make a very straight edge on steel or aluminum, which can be set accurately like a dial cal
21:23 dumbass-afk i am thinking of mounting a grinder on a trolley, on a 2ft long rail, fastened to a 2ft bar below it, which i can clamp the work piece to it to grind by pushing the trolley back and forth
21:24 dumbass-afk that way i can straighten the edge of 19" stuff
21:32 rue_shop3 it took a lot to fix the last leak in the boiler system
21:32 rue_shop3 its all up and running now
21:32 rue_shop3 almost out of firewood
22:36 dumbass-afk hmm, sometime in the last hour, i dozed off, considering what i have been eating abd drinking, that's not surprising, but i woke up again, and that's a lil surprising
22:49 dumbass-afk #1
22:49 dumbass-afk Precision Picosecond-Pulse Measurements Using a High-Quality Superconducting Delay Line
22:49 dumbass-afk Andrews, James R.
22:50 dumbass-afk finally a reason to use my Superconducting Delay Line
22:54 dumbass-afk A model for the interaction of oscillations and pattern generation with real-time computing in generic neural microcircuit models
23:07 dumbass-afk =======
23:07 dumbass-afk The GS1220 has 468 x 668 pixel display. The graphics area is 468 pixels
23:07 dumbass-afk square and the remaining area is used for menu boxes, an online reference
23:07 dumbass-afk guide and the user response area. Other hardware includes 8 in floppy disc
23:07 dumbass-afk and Winchester disc drives. 256 kbytes memory is included as standard. Space
23:07 dumbass-afk is available for adding up to 256 kbytes for the graphics processor and up to
23:07 dumbass-afk 512 kbytes for the command processor. The system costs $55 250.
