I'm still trying to get my rig all in the case!. I have to take things step by step due to severly limited funds :shrug:. I'll probly use the same flow sensor because of the cheap cost
. is it very restrictive?, has it got a spring inside?, or is it gravity/airtight~pressure that opens the connection?...
Thinking about a relay for the 240AC, it'll be hard to switch on because the power is'nt going to be there to activate a timer!. if only it'd only close/open the connection on the relay while the PC is powered. if you know what I mean.
a simple push and hold button would work!!, if it shorted/bypassed the connections on the relay while held down (as well as turning the PC on!), it'd have to be held down long enough for the pump to start flowing>sensor~ switch to close> relay to make connection, what do you think?, be easier would'nt it?...
