The nerves remote meetup is getting started soon and it seemed like a good idea to get a parts list put together. This should work for anyone following along with the meetup or for people watching the recording later.

Note: if you have micro SD cards, micro USB charge cords etc laying around, you can probably just use what you have.

For this project we are planning to re-use most of the existing wiring that your sprinkler control board has avaiable. Here is a picture of my sprinkler control board.

The main 24VAC power line comes into the top-left and I plan to just tap into those in order to power the relays. The small boxes in the middle are the power inputs for each of the valves so I plan to wire my relays to those same inputs.
