hello! i bought a sainsmart 8 channel relay with the hope of adding it to my rpi. i have found a few tutorials on the internet, but they are saying i need a 10k ohm resistor....do you think that is needed? my goal is to have 8 zones (plumbing them this week) hence the 8 channel relay. think i should of just bought the package deal from opensprinkler?
umm, you guys do realize that poly will eventually leak, right? mainly from not being winterized properly, it will split and crack, but time alone will also have the same effect. a sprinkler system made out of either schedule 40 or 80 pvc is, hands down, the best way to go....more expensive than poly and installation is more time consuming, but it will be done right. i'm not really sure what some of the comments are referring to....yes, if pvc is exposed to uv rays it will no doubt become brittle but this is a sprinkler system, the pipe doesn't stay above ground lol
.....any idea what benefit there was in pairing a cellphone to a charger at only 300mah instead of 700mah, like yours? maybe even 1ah? i guess cell phone makers thought we had nothing else better to do back then but wait for phone to charge : )
i wonder why they only put a 300ah battery charger from the factory? why not put something like 700ah
