02:33 theBear oh yeah rue, don't spose you got a pinout/the cd-shaped-official-paperscrap or just the avrdude/whatever with the pindefs for rif's original series of buffered parport stk thingers somewhere
08:39 rue_school is it rifs or mine?
08:39 rue_school 6 or 10 pin?
13:24 Snert__ If I want to put limits on the travel of a slider mechanism, are physical switches considered more reliable as opposed to say an opto detection scenario?
13:35 Snert__ Or what would be the most reliable method?
13:45 wolfmanjm I prefer micro switches opto can be mistriggered from fluorescent light etc
13:46 deshipu Snert__: I guess a big block of metal would be quite reliable for stopping stuff
13:48 Snert__ I'm thinking of a secondary fail safe type of thing. In addition to closed loop control, I want an outside 3rd party independant assessment of travel limits.
13:49 Snert__ like limit switches that kill the juice to the motors - no computer control...perhaps monitored by the MCU but independant of it.
13:50 Snert__ wolfmanjm: you bring up a good point about opto.
13:50 Snert__ IR would be bad in sunlight too.
13:51 Snert__ ... and a block of metal isn't out of the question either.
13:51 Snert__ If absolute physical safety is a factor.
13:55 deshipu HULK SMASH
13:56 Snert__ in my case, physical safety would stop just equipment damage, not really protect a carbon life form.
13:57 Snert__ hold it...could be my cat.
13:57 Snert__ so I dunno.
