Anyone got homemade timer plans?
I'm considering trying to make my own hydroponic timer for a new ebb/flow table I'm building. I'm pretty comfortable with a soldering iron and I understand basic electronics but any helpful hints that others might be able to provide would be appreciated.
Ideally what I want to build is a 110V relay that is controlled by a 555 timer. The idea is that it could trigger a pump to turn on for about 3 minutes and be off for about an hour.
The internet is a wealth of information about 555 timer setups but it is hard to seperate the wheat from the chaff. If anyone has tried this before or at least researched it and has useful links they can share I'd appreciate it.
If I am able to make something that works, I'll be glad to type up a parts list and directions so others can use it.
Thanks in advance,
