[14:57] <natrium42> ...
[14:58] <natrium42> it's a bad idea to put that into a bot, since it can be triggered by a loss and gain of connection...

[17:29] <weather> hey all
[17:30] <edmoore> hi weather
[17:30] Nick change: weather -> Laurenceb
[17:30] <Laurenceb> I'm still here argggg
[17:30] <Laurenceb> just got PID control working on my vacuum pump, using feedback from a differential pressure sensor
[17:31] <Laurenceb> I was confused for ages as printf wasnt working, it hadnt linked to the printf_flt lib
[17:32] <Laurenceb> then I didnt realise that linux doesnt automatically save to HDD, and lost about 2 hours work :(
[17:34] <edmoore> sounds about right
[17:34] <Laurenceb> very very annoying
[17:34] <Laurenceb> I'll have to redo it whilst its still in my head
[17:35] <Laurenceb> I cant even get wifi down in the lab :(
[17:37] <Laurenceb> strangely if you put 0v into a 081 opamp non inverting input, the output will always go to Vcc
[17:40] <pattm> with the inverting input also tied to 0v?
[17:41] <Laurenceb> no
[17:41] <Laurenceb> tied to output, its a buffer
[17:41] <pattm> oh weird
[17:42] <Laurenceb> you can fix it with a couple of resistors
[17:42] <Laurenceb> as long as +input is a few millivolts
[17:43] <Laurenceb> this isnt a split rail, so by 0 I mean v-
[18:04] <Laurenceb> so, what do you do to be sure your files are save on linux?
[18:11] <pattm> sync
[18:11] <pattm> flushes filesystem buffers to disk
[18:13] <Laurenceb> ok thanx
[18:13] <Laurenceb> probably a good thing to use :P
[18:14] <Laurenceb> I tried to install google earth and crashed it badly
[18:15] <Laurenceb> hopefully the ngw100 boards will arrive on monday, we ordered 3 :D
[18:16] <Laurenceb> can you talk to a serial port with python?
[18:22] <Laurenceb> gtg cya all
