00:09 rue_shop3 !?!?! the hole is too small for 4-40
00:09 any98604438 6-48?
00:09 any98604438 err
00:09 any98604438 2-48
00:10 any98604438 Tiggr has data on 7 screwsizes smaller than 4-40
00:11 rue_shop3 I have no M2 nuts
00:11 rue_shop3 all my nuts are bigger than M2
00:11 rue_shop3 all of them!
00:11 any98604438 4-40 ; 3-56 ; 3-48 ; 2-64 ; 2-56 ; 1-72 ; 1-64 ; 0-80
00:11 rue_shop3 well, that puts a halt on this project for tonight
00:12 e_shop3 wonders if, by the time your at #0 if the threads really matter any
00:13 any98604438 .0125 per thread? sure
00:13 any98604438 might rust up overnite if you breathe on it
00:22 e_shop3 wraps the project in tape and install
00:23 y98604438 gets some popcorn and wat
00:32 rue_house I had great fun with the project
00:32 rue_house completely sensless effort
00:32 rue_house so
00:33 rue_house the goal was to make a water level switch for the well pump
00:33 rue_house the ludicrous idea was to use a capacitive analog level sensor
00:33 rue_house it would require a simple system
00:34 rue_house consisting of a 555 that used a set of wires as a variable capacitor for an oscillator
00:35 rue_house two 555's in missing pulse mode that would compare the first signal to a 'high' and 'low'
00:35 rue_house and another 555 that would operate as a flipflop, latching the output for a relay on and off
00:36 rue_house so, I got it all working,
00:38 rue_house an avr uses two IO pins to charge and test the 'dipped capacitor', one of the pins goes thru a 10M resistor to charge the cap, while another pin senses the level. it goes thru resetting and charging the cap, timing it out, then it compares it to two values set in EEPROM for high and low, and latches the output for the relay on and off as required, there is an acitive serial port with a console that lets you read the level and rewrite the
00:38 rue_house high and low level values
00:38 rue_house ;)
00:50 any98604438 too cool
01:02 any98604438 how much do you sellt hem for?
01:12 any98604438 woah, this guy is paranoid
01:13 any98604438 he nuked all the ram/bios and drilled all the hdds, and pried all the chips off the mobos
01:13 any98604438 so the dog in his appt peed all over his bed
01:14 any98604438 by "nuked", he put them into the nukebox and set them on fire
01:22 rue_house !?
01:22 rue_house why is a person doing that?
01:22 any98604438 he wasn't sure if the site he broke into was too easy or not
01:28 rue_bed ok...
01:37 any98604438 i didn't write it
01:37 any98604438 he's a hacker character on tv show "Mr Robot"
01:50 y98604438 makes note to never sit on railings 30ft over sharp r
02:17 any98604438 k
16:22 any66918174 "Will a 900 v invertor support a tv a fan and an ac ?" "If it is strong enough, and you can balance the items on it. I'd put the tv on the bottom, since it's heaviest."
18:00 Tom_itx 18 billion payout fro BP
23:38 zhanx Evening
23:39 rue_shop3 arg
23:40 rue_shop3 measuring the angular range of the writsts axies is freaking hard
23:40 zhanx Pissed off the wife today, saw dust pile etc
23:40 zhanx Making a lathe
23:45 rue_shop3 I think I figured out the mecha wrist
23:46 zhanx Pics?
23:48 rue_shop3 no Im just laying out on the table
23:48 zhanx K, same here
23:48 rue_shop3 its 3 peices of pipe, the 2.25" sch 80
23:49 zhanx Lathe out of a washer
23:49 rue_shop3 [] [] []
23:49 zhanx Had 3 pullys on it for some reason
23:49 rue_shop3 they have link bars fixed on the outter pipes, pinned into the middle one
23:49 rue_shop3 a washer?
23:52 rue_shop3 so, there are 2x 3/8" bolts holding each dimension of the joint
23:53 rue_shop3 and its hollow, for cables
23:53 zhanx Nice
23:53 zhanx I am building my shop up now
