00:39 Anniepoo 8cD the lathe feed now works
00:40 Jak_o_Shadows nice
00:46 Anniepoo 8cD makes a horrible grinding noise in the change gears, and the back gear engagement lever lock is missing, but it's getting there
00:46 Anniepoo 8cD
00:47 Anniepoo The Bridgeport's in two pieces
00:47 Anniepoo The other Logans still in pieces from the move, and we need to run power to it

04:04 deshipu rue_shop3: http://letsmakerobots.com/robot/project/dancing-chinese-lion-mkii
04:04 deshipu rue_shop3: this is something in your ballpark, I guess :)
04:11 Jak_o_Shadows I dn't see 8 DOF there.
04:13 deshipu eyes?
04:13 deshipu maw?
04:13 Jak_o_Shadows mouth? Yeah, good point.
04:15 Jak_o_Shadows also, his previous thing seems like it would've been a lot more feasible if he'd just stiffened up those boxes.
04:16 Jak_o_Shadows https://www.youtube.com/watch?v=H3KXL_WopZc
04:16 Jak_o_Shadows Torsion boxes don't do much if they arn't actually boxes
04:16 rue_shop3 hmmm
04:17 rue_shop3 thats cool
04:20 Jak_o_Shadows Seriously, if he had sheeted that paralleogram one, I reckon it would've worked
04:20 Jak_o_Shadows Through, it's probably a good thing that the new design doesn't have any lateral movement.
04:29 deshipu Jak_o_Shadows: it would become even heavier
04:30 deshipu I think that going for the lightest possible solution works very well most of the time
04:30 deshipu inertia is a bitch
05:37 rue_shop3 hmm avr capacitance meter
05:38 rue_shop3 I'v got it charging a capacitor thru a 10M resistor while it counts as fast as it can and its still a bit too fast
05:45 Jak_o_Shadows inertia is a bitch, but so is a complete lack of any stiffness
05:46 Jak_o_Shadows Ok, well, if the individual bars are closed squares, you could probably get away with gussets
13:26 rue_house who is he that has network interface problems
13:26 rue_house with static ip
13:26 rue_house WHO IS HE!
13:27 Tom_itx JT-Shop you around?
13:27 rue_house SHOW YOURSELF OR I SHALL SMITE YOU!
13:28 rue_house YOUR LINING UP FOR A SMITING
13:55 JT-Shop yea
13:56 JT-Shop tis I who remain confused about static ip configuration
13:59 rue_house show me your /etc/network/interfaces file
13:59 rue_house there is no traffic here, I dont care if you dump it in the channel
14:00 JT-Shop ok
14:01 JT-Shop # The loopback network interface
14:01 JT-Shop auto lo
14:01 JT-Shop iface lo inet loopback
14:01 JT-Shop allow-hotplug eth1
14:01 JT-Shop iface eth1 inet static
14:01 JT-Shop address 192.168.0.120
14:01 JT-Shop network 192.168.0.0
14:01 JT-Shop netmask 255.255.255.0
14:01 JT-Shop broadcast 192.168.0.255
14:01 JT-Shop gateway 192.168.0.1
14:01 JT-Shop on this computer
14:01 rue_house ok change eth1 to eth0 and restart it, it'll work fine
14:02 rue_house er,
14:02 rue_house change allow-hotplug eth1 to auto eth0
14:03 Tom_itx don't listen to him.. he's nuts
14:03 JT-Shop closed the wrong window lol
14:03 Tom_itx but he does know linux
14:03 rue_house oh cmon, I have to be paid more to repeat myself
14:03 rue_house zlog
14:04 rue_house ^^ read what I said
14:04 Tom_itx which line?
14:05 Tom_itx the first one or the last one?
14:05 Tom_itx <rue_house> ok change eth1 to eth0 and restart it, it'll work fine
14:05 rue_house 1) change eth1 to eth0
14:05 Tom_itx <rue_house> change allow-hotplug eth1 to auto eth0
14:05 veverak well
14:05 veverak can someone explain me
14:05 rue_house 2) change allow-hotplug eth1 to auto eth0
14:05 rue_house 3) restart computer
14:05 veverak what "network,netmask,broadcast" exactly ... doeS?
14:05 verak can't find article explaining something so b
14:05 rue_house ask in 9 hours
14:06 JT-Shop my DHCP IP Address Range : 192.168.0.100 to 199
14:06 Tom_itx i'd set the 0.120 to a higher one for safety but it still should work
14:06 rue_house ok then change the address if you want
14:07 Tom_itx so DHCP won't interfere with it
14:07 Tom_itx bak in a few...
14:07 rue_house if you pick a static ip on the dhcp range, and dhcp machines will figure out the conflict and avoid it
14:07 JT-Shop ok
14:07 JT-Shop be back I hope
14:08 verak usually prefers to tell the dhcp server to give specific ip for specific mac adre
14:08 rue_house auto lo
14:08 rue_house iface lo inet loopback
14:08 rue_house auto eth0
14:08 rue_house iface eth0 inet static
14:08 rue_house address 192.168.0.42
14:08 rue_house network 192.168.0.0
14:08 rue_house netmask 255.255.255.0
14:08 rue_house broadcast 192.168.0.255
14:08 rue_house gateway 192.168.0.1
14:14 JT-Shop and it works, thanks rue_house
14:15 tws2172 hello
14:15 i_tarzan h
14:17 rue_house yea
14:23 wolfmanjm when did it become OK to have a zero in the IP address? I know people do it all the time, but back in the day it was reserved.
14:26 rue_house its ok if it dosnt' end in 0
14:29 Tom_itx rue_house, you get him fixed up?
19:04 rue_shop3 yup
19:04 rue_shop3 it was just what I said
19:04 rue_shop3 he'd changed back to an old machine and the ethernet interface number was wrong
19:05 Tom_itx rue_shop3 i feel fine now
19:06 rue_shop3 I have an avr circuit beside me here measuring the capacitance in 16" of wire
19:06 rue_shop3 at '305'
19:06 rue_shop3 which is pretty good ersolution for only 16" of wire
