13:27 tsmeow-afk notes she has no *dip* t13's and says "o
16:02 katsmeow-afk ooooooooooooooooooooooo:
16:02 katsmeow-afk Set of 10 32 pp., 7 x 8-1/2"

16:02 katsmeow-afk $29 , free s&h
16:03 katsmeow-afk fascinating
16:03 katsmeow-afk for the reader who is not easy bored, i spose
16:13 tsmeow-afk studies one of the sample p
16:14 katsmeow-afk The commuter train that crashed in the Bronx on Sunday was going about 82 miles per hour as it entered a 30-mph curve, NTSB member Earl Weener said Monday.
16:15 katsmeow-afk Paul Walker crash: Witnesses saw a 'single speeding car', drag racing itself, it is unclear who the winner was.
16:16 katsmeow-afk Here's why koalas sound like frogs vomiting during mating season........... nevermind
18:03 katsmeow-afk damned news just said the $450,000 sports car can go from zero to 25mph in under 10 seconds
19:12 katsmeow-afk 24,736 results in
19:12 katsmeow-afk Medieval & Renaissa
19:55 rue_house huh
19:55 rue_house I was trying to think what I'd use for a non-inverting line driver and it struck me
19:55 rue_house to use a line driver
19:59 katsmeow-afk that may work
20:00 katsmeow-afk some 7000 74fct244 just went for dirt cheap on ebay, under $10 iirc
20:03 katsmeow-afk ah, there's another 7200 on ebay for $29 plus $41 s&h (to be fair, 7200 dip-20 really are heavy)
20:04 katsmeow-afk but there's 100 pcs for $19 + $6 s&h
20:06 tsmeow-afk has adequate stock of abt245's and abt16245's and some other stuff, and way more 373's than anyone could ever
20:06 tsmeow-afk does need to eat dinner
20:12 katsmeow-afk a song was just on the radio that took me years to understand, i didn't know what the guy was saying, didn't know if it was a new religion, flower, african tribe, ritual, or what, he was saying "the bezenviemee"
20:12 katsmeow-afk i finally figured it out
20:13 katsmeow-afk i didn't clearly hear the lyrics to "the lift goes up where we belong" till 10 yrs later when someone put out a hifi edition with cleaned up vocals, but yesterday i heard it on the radio in the original words
20:16 katsmeow-afk finally, with 80% of the world covered with this stuff, it's FINALLY being sold on ebay!! : http://www.ebay.com/itm/181270737062
20:18 katsmeow-afk at $2/gallon, it makes that robotically dug pipe from Tom to the Gulf of Mexico sounds even better, no?
20:34 Tom_itx what did i do?
20:34 Tom_itx my xilinx is working finally
20:37 tsmeow-afk takes the pizza out of the oven for Tom to celeb
20:43 Tom_itx since i robbed one encoder of a channel, xilinx assigned the 'open' pin to zero
20:44 Tom_itx i had to invert the count for it to read positive on the dial
20:44 tsmeow-afk has a querstion: how is this chip better than using an avr in this applicat
20:45 Tom_itx much faster
20:45 katsmeow-afk a 20Mhz avr is too slow for your button pushing speed?
20:46 tsmeow-afk simply doesn't know, so is as
20:46 Tom_itx too slow for steppers stepping at 40000 per rev
20:46 katsmeow-afk err,, you are counting and processing each step as it happens?
20:47 katsmeow-afk 40,000 ticks per revolution? shirt!
20:47 Tom_itx err maybe that's per inch.. i forget
20:48 katsmeow-afk a 3ft dia disk stepped at 40,000 ticks is .0028 per step at the circumference
20:49 katsmeow-afk a 3in dia disk stepped at 40,000 ticks is .000235 per step at the circumference
21:00 Tom_itx oh and this card runs at 75Mhz
21:02 Tom_itx here's the .vhd file i ended up with: http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/bitfiles/PIN_SVST2_4_7I47SSS_48.vhd
21:05 tsmeow-afk nods sl
21:44 katsmeow-afk �We were excited� by seaweed, says, Ms. Hasna, the Bantaeng farmers. If the weather is good, she says, some farmers could earn as much as $2,000 a month, and prices never went downl.
21:51 Tom_itx http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/bitfiles/showpin.txt
21:51 Tom_itx that's a helluva lotta io
21:52 Tom_itx one card has 48 ouput, the other has 32 input and 16 output
21:52 Tom_itx 12 bit IN FALSE hm2_7i43.0.7i71.0.1.output-00
21:52 Tom_itx starting there
21:59 katsmeow-afk what's a halui ?
22:00 katsmeow-afk ~early 1984, i had well over 100 io lines to a C64, and most of those were 8bits wide
22:00 Tom_itx hal user interface
22:01 Tom_itx hal is the language they use to program pins
22:02 katsmeow-afk had 2 19" card racks full of cards, tween 8 and 32 blinky lites on each card
22:03 katsmeow-afk i designed and made the cards, programmed the C64 to use them
22:03 Tom_itx nice
22:03 katsmeow-afk in 1984 i could walk well, run and jump and play, right thru the end of 1985, and then i became useless with a bad back from falling
22:04 katsmeow-afk it's a sucky criteria for qualifying a desk job
22:04 Tom_itx the 7i43.0.7i71 there indicates 2 cards. the 43 is the first card and the 71 is interfaced to it via RS422
22:05 tsmeow-afk will take your word fo
22:05 Tom_itx so to access the pin you need to include the whole line
22:05 katsmeow-afk is this a system you will be using to expand your cnc abilities?
22:05 Tom_itx i just wanted to play
22:05 Tom_itx i may use it for some io if i need it later on
22:05 katsmeow-afk you could play your way right into a profitable small business tho
22:06 Tom_itx at first i thought i'd need it in order to wire it in because i would lose an encoder
22:06 Tom_itx but i juggled the pins around so i didn't lose anything
22:06 Tom_itx and i wanted to get better at making those xininx bit files
22:07 tsmeow-afk bobble-h
22:07 Tom_itx and
22:07 Tom_itx it was all free
22:07 Tom_itx at least those cards
22:07 katsmeow-afk :-)
22:07 Tom_itx and the xilinx tools
22:10 katsmeow-afk i just broke firefox
22:11 katsmeow-afk apparently there is a key-mouse combo that will lock the keybd focus tot he filename box
22:11 katsmeow-afk when saving a webpage
22:11 katsmeow-afk so the dir and filename cannot be changed
22:12 Tom_itx huh
