03:20 Jak_o_Shadows yeah, fun hey.
03:20 Jak_o_Shadows Haven't heard from some friends in queensland, i would've figured they would've shown off the flooding, ignroing the lack of power

04:28 RifRaf ok thanks
05:02 ali hi \
05:02 ali do you know any channel regarding electrical engineering?\
05:06 Jak_o_Shadows #electronics?
05:06 MjrTom ##electronics
05:06 Jak_o_Shadows gets a lot of chat there
17:20 meysam hi
17:21 ace4016 hello
20:21 Tom_itx yay
20:21 Tom_itx lcd works anywhere i put it now
20:35 theBear hooray ! where did it used to work ?
20:35 theBear loungeroom ? porch ?
20:35 Tom_itx damn straight
20:40 Jak_o_Shadows even in the bathroom?
21:19 RifRaf got a variety of sg90 servo brackets to test
21:20 rue_house rifraf, we need to get you coding
21:20 rue_house what do we teach you, you know bits of all sorts of stuff
21:21 rue_house RifRaf, shall we do an hour of coding?
21:21 Tom_itx mmm interesting
21:21 Tom_itx the arduino code doesn't use RW
21:21 Tom_itx i need to gnd it
21:22 Tom_itx however if i use my code it uses rw and must be on a pin
21:23 Tom_itx rue_house, RifRaf doesn't want to code right now
21:23 Tom_itx he's havin fun with that new lib he found
21:24 Tom_itx i'm learning all sorts of stuff doing this lcd experiment
21:24 Tom_itx learning about bootloaders and boot fuses etc
21:26 Tom_itx rue_house
21:26 Tom_itx do you know how to compile a program so it loads in a certain part of flash?
21:26 Tom_itx or does it matter?
21:26 Tom_itx ie for a bootloader
21:28 RifRaf i am at work rue
21:30 RifRaf made the brackets at lunch
21:31 RifRaf hopefully parts for an sg90 servo gripper as well
21:31 rue_house RifRaf, water receeded eh?
21:34 RifRaf still had to drive through it but yep, flash flood, sun is out now
21:37 Tom_L http://www2.electronicproducts.com/How_NXP_and_Cherry_s_battery_less_wireless_switch_works-article-fajb_CES_nxp_cherry_switch_jan2013-html.aspx
21:37 Tom_L clever
21:37 RifRaf tom you have your chip calculator link handy?
21:38 RifRaf wanna see if i am cutting this 3mm ally sheet right, 25mm/sec spindle/13000rpm 6mm single flute cutter
21:38 Tom_L i got disconnected
21:39 Tom_L http://www.engbedded.com/fusecalc/
21:39 Tom_L oh not that one
21:39 Tom_L http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
21:40 Tom_L RifRaf, what are you cutting?
21:40 RifRaf 3mm ally sheet
21:40 Tom_L and how many flutes
21:40 RifRaf single
21:40 Tom_L 2 flute is best for al
21:41 RifRaf 25mm/sec 13000rpm
21:41 RifRaf ok will get a few
21:41 Tom_L .004" chip load should be ok
21:41 Tom_L you can download that fswizzard
21:41 Tom_L to your pc
21:42 RifRaf ok wioll do, for most stuff i just use 18000rpm but slow it down for the a;;y
21:43 Tom_L are the carbide?
21:43 RifRaf yeah
21:43 RifRaf have to cut out all these small letters using a 3mm bit too, am doing 15mm/sec 13000 rpm for it
21:43 Tom_L diameter?
21:43 RifRaf they cut out nice, 3mm
21:44 RifRaf didn't even break a bit today :)
21:49 Tom_L .05 chip load
21:50 RifRaf so alot heavier than the 6mm bit?
21:51 Tom_L i may not be using that calc right
21:51 RifRaf the chips looks good and are cool when they come off, normally means its close
21:57 Tom_L that looks like .07 mm per tooth
21:58 Tom_L 122.5m/min
21:59 Tom_L that's movin right along
22:00 RifRaf i go upto 150mm/sec for some jobs
22:01 RifRaf 15m/sec is only .9m per minute, or you mean the tool bit?
22:01 RifRaf 15mm*
22:02 Tom_L seconds to min is *60
22:02 Tom_L so 15mm/sec is 900mm/min
22:02 Tom_L or .9m
22:02 Tom_L my cad cam took mm/min input
22:03 rue_house I should amke mine take km/hr
22:03 rue_house just as a joke
22:04 Tom_L i should get my smps soon
22:05 Tom_itx at least i figured out what was going on with the lcd
22:05 Tom_itx it initially worked with the arduino code but they ignore the RW pin somehow
22:25 RifRaf are you using the arduino ide tom? its pretty aweful eh
22:26 Tom_itx i have it loaded but i'm not using it much
22:26 Tom_itx have it for 1 project
22:27 RifRaf its hard tio get the code out and do your own thing with it
22:27 RifRaf and it hides hex files, found them though
22:27 Tom_itx so did i
22:28 Tom_itx it also erases them when you close the project
22:28 RifRaf this next sheet is gonna use up the rest of the day nicely, then can go try these drackets
22:28 RifRaf yeah sucks
22:38 rue_house !thislog
22:38 tobbor This one: http://rueshouse.dyndns.org:82/~ircjunk/irclogs/html/%23robotics-2013-01-29.html
23:30 RifRaf see yas on the home side, if the phones are fixed out there
23:45 rue_house wow: 8 years of its logs breaks down to a list of 3.5M of words
23:45 rue_house thats it
23:46 Jak_o_Shadows Make a chatbot out of it
