I had a garden I wanted to drip irrigate one time and all the little rainbird plastic drippers were one-gallon per hour, but I did not have enough water to feed them at that rate. If i just let water at low pressure run into the irrigation hose, it would all drip out at the lowest elevation drippers. If I fed the water at pressure, I would need a timer and switch. I found a non-electronic solution that I think others might also be able to use:
I made a super-sized "deer scarer": This is a Japanese-garden feature popularized by one of Kill Bill's final scenes. A pipe closed at one end is mounted on a pivot. Water drips into the open end and when enough water accumulates, the pipe tips and dumps its water all at once. I had the irrigation hose connected to a feed tank, and the feed tank was periodically filled by the giant deer-scarer. The dripper rate was not nearly high enough to feed all the individual hose drippers, but they all were fed evenly from the feed tank when it would be periodically filled. Eh? You like? It also sounded cool when the water dumped into the feed tank.
