03:38 katsmeow-afk cyborgs just blew the heck outa that cathedral
04:16 rue_house did they appologize?
04:16 katsmeow-afk no
04:16 katsmeow-afk you ok?
04:17 rue_house I was asleep
04:17 rue_house I'm trying to doe soemthing
04:17 rue_house code
04:17 rue_house just kinda beating my head against it
04:18 katsmeow-afk oh
04:19 katsmeow-afk looks like robotic doves were used as a radio mesh to hack the M$ virtual reality headsets, and caused the riots
04:23 rue_house hmm m$
04:24 katsmeow-afk mickey string
04:28 katsmeow-afk appleseed seems to be a series of robot-cyborg anime movies
04:30 katsmeow-afk heh, the cops using subcompact cars, to make up for the lack of macho cars, they made the blue/red lights bigger
15:55 rue_house heh
15:55 rue_house the LDRs arrived!
16:00 rue_house what was I going to make with them?
16:01 rue_house hmm serial computer
16:01 rue_house you must have to have a storage register fro some things
16:01 rue_house I suppose if your only fed one bit at a time, adding w/carry is easy
16:06 katsmeow-afk yeas
16:46 katsmeow-afk hmmmmmmmmmmmmmmmm
16:47 katsmeow-afk i could swear the readme papers for the respirator weigh more than the respirator
16:50 katsmeow-afk rue, imagine a stack of 4 7474, each wired like in a 75269, but with a mux gate on the clk input, to switch between the common 74269-type clk and the serial buss
16:50 katsmeow-afk you toggle the mux with a shift register, and at the start of the add you load 1 into the lowest reg of the shift register
16:51 katsmeow-afk you preload the stack of 74747 like you do a 74269, then you send in the next byte serially
16:51 katsmeow-afk each clock clocks the shift register
16:52 katsmeow-afk you send in lsb first on the serial line, and each bit goes to the next msb as the serial byte is clocked in
16:52 katsmeow-afk in effect, the serial bits are chasing any carry bit up the stack of 7474
16:53 katsmeow-afk you have no lag from ripple carry, because it's faster than your serial clock anyhow
16:53 katsmeow-afk you'll need to image any more glue chips yourself
17:00 katsmeow-afk this scheme is feasable really only if you must clock in the 2nd number anyhoo
17:01 katsmeow-afk but it steers the bits to the appropriate same bit in the 1st number, so the ripple carry gets shorter and shorter, and tehre's never a ripple carry incoming to the bits you are trying to add
17:03 katsmeow-afk when you have clocked the last bit in, the complete add is already done
17:05 katsmeow-afk if you are making an all-serial cpu, you can prolly adapt this down to one 7474, one eor, one or, one and and a couple invertors, and add two numbers of any length as fast as you clock them in you get the answer clocking out at the same time
17:07 katsmeow-afk i wonder why anyne would make a 1-bit cpu core
17:25 katsmeow-afk ah hah, making a 1-bit cpu with one attiny13 for each bit, you can stack up the bits,, but for carry and borrow you may need tiny44's
17:26 katsmeow-afk i wonder how many functions you can put to one tiny avr if it's working on only one bit and the carry in/outs
17:28 katsmeow-afk or two bits, for math and logic
17:29 katsmeow-afk "what is this board full of tiny13's do?"
17:30 katsmeow-afk "each row is one32bit cpu, which i can make into 2rows=one64bitcpu or 4rows=one128bitcpu or 8rows=one256bitcpu
17:32 katsmeow-afk 2 bits goto serial ram, 2 bits goto cpu above, 2 bits goto cpu below, 2bits for pwr&gnd
17:33 katsmeow-afk or use a slightly larger chip, and you can connect a couple pins diagonally too
17:33 katsmeow-afk and it becomes a neural net
17:34 katsmeow-afk atm, attiny13A-SU are under 50 cents each on ebay
17:35 katsmeow-afk ouch, a 50x50 net would still cost $1000
17:43 tsmeow-afk ponders such a line of tiny44's, each with a software-tuneable bootstrapped twin-t audio filter, that can listen to music in real time and tell you what's playing, or at least understand what you are sa
17:43 katsmeow-afk and who is sayingit
18:00 rue_house I'm back
18:00 rue_house it took a month, but I'v done the recycling
18:09 rue_house kat do you know why my zero crossing triac optos cant switch a triac with a 13Vload?
18:09 rue_house I get the impression there are too many voltage drops
18:10 rue_house http://www.rotwang.co.uk/images/triac_drive.gif
18:10 katsmeow-afk ?
18:10 rue_house at 13VAC its not working
18:11 katsmeow-afk 200 ohms may be too high at 13vac if it's calculated for 120vac
18:11 katsmeow-afk try 47, 33, 20 ohms
18:12 rue_house I think I tried down to zero
18:12 katsmeow-afk did you blow at teh diac at zero ohms?
18:12 katsmeow-afk er, moc3020
18:13 katsmeow-afk seeif you get any toggling on pins 6-4 wheny ou lite the diode
18:13 katsmeow-afk what sorta load do you have on the triac ?
18:17 katsmeow-afk i can still smell the stink of burning crap on my sweater
18:24 katsmeow-afk wwoooaaahhhh : SRAM 144Mb, 1.3V, 933Mhz 4Mx36 QDR-IV HP SRAM ; $318 + s&h
18:39 tsmeow-afk pokes
19:06 m_itx pokes katsmeow-afk for poking
19:06 m_it
19:06 Tom_itx MPG came today... yay!
19:07 katsmeow-afk yay!
19:08 katsmeow-afk and i found this: http://www.ebay.com/itm/4-Oz-Plastic-Jar-Clear-Pet-Jar-with-White-Rebbed-PE-Lined-Caps-Case-of-25-Pcs-/121554425520
19:09 katsmeow-afk as in, under $1 per jar for storing tiny parts like terminals, bearings, 1/8 roll pins, 4-40 screws, 6-32 nuts, etc in
19:13 Tom_itx i got a box of baby food jars for that
19:13 Tom_itx seldom use em really though
19:14 katsmeow-afk babyfood like glass?
19:14 tsmeow-afk has no ba
19:15 m_itx doesn't ei
19:15 katsmeow-afk how does you get the empty jars?
19:16 Tom_itx neighbor long time ago when their kids were really short
19:16 katsmeow-afk oh
19:18 katsmeow-afk loks like the cost of shipping heavy glass makes them cost more thanthe new plastic ones on ebay
19:18 Tom_itx probably so
19:24 katsmeow-afk yanno, a bus has alot of roof area, could prolly support several 100 hp of condenser for a steam engine
19:49 katsmeow-afk http://www.ebay.com/itm/DC-0-100V-Red-Blue-LED-10A-Dual-Digital-Voltmeter-Ammeter-Panel-Amp-Volt-Gauge-/171487319783 $3.46 free s&h china
20:04 any17203401 <cough>
20:04 y17203401 ponders turning 12vdc@1amp into 0.1vdc@120
20:27 katsmeow-afk the *order* of the words means something too, so it's NOT "how, hi are you?"
20:29 katsmeow-afk cusswords,,, making a 0.1v high current psu means the psu will dissipate over 7x as much power as it delivers, just in the regulator and rectifiers
20:29 tsmeow-afk unslaps
20:31 m_itx gives katsmeow-afk a box full of w
20:31 tsmeow-afk happily plays in
20:34 katsmeow-afk "she only wears pants" != "only she wears pants"
20:36 katsmeow-afk yet human sprinkle the word "only" at the beginning of sentences like that's where the word always goes
20:39 katsmeow-afk so saying "he has only lost one election" makes no sense, because you can only win , only lose, or only tie, you cannot do any 2 of the 3 , or all 3 , you can do only one of those for any election
20:40 katsmeow-afk it's as if yo can say "he only lost the 2010 election, but he won and lost the 2014 election"
20:46 katsmeow-afk "she only eats apples" does not mean she doesn't eat oranges too, what it means is she only eats apples, she doesn't wash them, peel them, slice them, or core them, she only eats them
20:49 tsmeow-afk runs into the
20:55 katsmeow-afk 50 drops of fabric spaced 5/8 apart is ~31 inches
21:15 katsmeow-afk "see my new phone? i got it because my daddy fell for that ad on tv that said you only pay for the features you like, and they mean it!, they would not let him use the features, he can only pay for them, so he gave me the phone!"
21:19 katsmeow-afk Alabama authorities say a tractor-trailer crashed on Interstate 20 because the driver lost control while he was pulling one of his teeth.
21:19 katsmeow-afk http://www.abc3340.com/story/27984145/troopers-trucker-blames-loose-tooth-for-crash-on-i-20-near-tuscaloosa
21:22 katsmeow-afk i wonder how the driver decided that it was ok to stop driving the truck while continuing to go 70mph, and practice dentistry on himself
21:36 katsmeow-afk going to take 25 8ft sticks of 1/2 cpvc for roller-spacers and hangers, at a cost of $70 plus tax,, and i'll have a small pile of qty75 3-5inch pieces left over
21:39 katsmeow-afk each roller-spacer will cost ~$1.03 each after taxes
21:40 katsmeow-afk what else can i use that's tween 1/2 and 3/4 inch diameter?
21:44 katsmeow-afk didn't someone make 3/8 pvc?
21:45 katsmeow-afk cusswords, i should use the cpvc because of heating
21:46 katsmeow-afk 1/2 pvc is .84 OD
21:48 katsmeow-afk i cannot use pex or abs for the 29 inch wide rollers, it's too bendy
21:54 tsmeow-afk growls about 1/2 pvc being not made for hot water and being 0.1 too fat and being $1 less per s
21:56 katsmeow-afk ifi used it the cost per roller would be ~63 cents each, instead of ~$1.03
21:57 katsmeow-afk but the fabric will be 0.225 further apart, the box would need tobe 11 inches larger, and the humidity would take longer to rise
22:01 katsmeow-afk 1/2" Schedule 40 CPVC Pipe, .109" Wall
22:01 katsmeow-afk Qty 60: 5% off; Qty 120: 10% off; Qty 360: 15% off; $1.32/Foot
22:01 katsmeow-afk
22:01 katsmeow-afk 3/8" Schedule 80 CPVC Pipe, .126" Wall
22:01 katsmeow-afk Qty 60: 5% off; Qty 120: 10% off; Qty 360: 15% off; $2.08/Foot
22:02 tsmeow-afk s
22:03 katsmeow-afk again my best choce is the best choice, the 3/8 is shc80 so cost more than the sch40,, AND the sch80 has such a thicker wall that it prolly makes up for the smaller ID
22:16 tsmeow-afk sighs at the cost this may add up to, before even starting, but if it works properly, should make 100% safe drinking water out of rottingfish and sewagefilled mississippi river water fairly quickly and witout needing to replace filters every
22:22 katsmeow-afk i was reading of a boater complaining where they were, the water was so bad, every time another boat went by, their intake gunked up and the engine would overheat
22:23 katsmeow-afk they ran out of filters and had to be towed
