05:16 PM veverak: I wonder how are these reliable
05:16 PM veverak: my automatic flowering system has working 'the water part'

05:19 PM veverak: relays should control valve, pump, lights and fan

08:56 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Control3.jpg

11:16 PM rue_shop3: _unreal_, pics suck, I stopped using them back in about 2002
11:16 PM rue_shop3: so much that they are NOT worth free samples
11:16 PM rue_shop3: I'd rather pay for a few avrs than get free pics
11:17 PM rue_shop3: I suggest you go with grbl on an uno
11:17 PM rue_shop3: I already did tho,

11:24 PM rue_mohr: for balance feedback for my 12' robot
11:25 PM rue_mohr: it sure would be nice if making the rings weren't such an ordeal and I could focus on the actual project
11:48 PM rue_mohr: zhanx, well, neat rings tho, eh?
11:48 PM _unreal_: rue_mohr, I got my Relay in today
11:48 PM _unreal_: Heavy duty one

11:50 PM _unreal_: most things chines are smaller :)
11:50 PM rue_mohr: if its 40 chineese amps, it may only be about 25 north-american amps
11:50 PM _unreal_: which is still more then enough
11:50 PM rue_mohr: :)
11:50 PM _unreal_: considering most outlets only provide 15-16a anyways

11:56 PM rue_mohr: geez, that ones bigger than mine
11:58 PM _unreal_: you must feel emaskulated
11:58 PM rue_mohr: mines both too big and not big enough
11:59 PM rue_mohr: where am I going to put it and how am I going to move it there?
11:59 PM rue_mohr: its *just* big enough that *I* cant touch the ring
