Electronics

I just wanted lights with a computer. I decided not to deal with an electronic system for irrigation. Later, I will add a moisture sensor (or several sensors). The LED was from CREE and the drivers from RECOM. I like to use white LEDs vs blue and red because then you can see the green plants under the lights.

LEDs

Mouser #:941-CXA13040C00A20E8

Mfr. #:CXA1304-0000-000C00A20E8

Configuration

I wire these bad boys in parrellel AFTER using themarl glue to glue them to a heat sink. This is critical, running the LEDs without a heat sink may fry them. These LEDs are ony $1.78 but larger LEDs can be $50 ea. !

Raspberry Pi + Wifi USB Dongle

I got this on Amazon along with a case for like $65

Structure

I decided on a wood frame to house my LED lights and my raspberry pi. Also, the large wood frame would support further hacking. It acted as mostly a scaffolding. I wanted something on the quick and this worked. There is no CAD model for that yet. A stencil was used for measurements. Eventually, I will post some CAD designs for a laser cut version of this.
