Chicken Coop Motor Drive

Motor reversing door controller board for use in chicken coops

Introduction

I have had chickens for the past 10 years and have had multiple iteations of contollers to open/close a door via a linear actuator. The circuit requiered is pretty simple, but wiring quickly becomes messy as extra features and functions are added. This board was created to simplify all the messy wiring and functions of my custom coop controller.

Key Features

Detachable timer

Bring the timer inside and program it indoors in a warm house, in good light, with your glasses!

Manual Override

Open/Close the door without changing the timer

External status LED hookups

Instantly see door status at night by colored leds

Multiple linear actuator outputs

Photo Electric safety cutoff - Stops motion if a chicken is blocking the door.

Assembly

Assembly requires soldering. All solder parts are included.

Buy the kit at bsgelectronics or ebay

Parts Not Included

I am selling this board as a solder kit. In order to keep the cost low, these items you’ll need to buy yourself.

Weasch CN101A 12v Timer

Available on Amazon. Other timers might work, but get this one to ensure the connectors line up exactly.

External 12v LEDs

Use to display door, power, and beam status. https://www.ebay.com/itm/406938606988 https://www.ebay.com/itm/196760274076

Photo Electric Emitter and Sensor

I suggest one “E3F-5L” emitter and one “E3F-5DP2” sensor. Sensor is PNP NC. Available on EBay

Power Supply

This board is designed to run on 12v DC. Be sure to use a power supply that can deliver enough amerage to power your liner actuator(s). I am using this 5A supply from Amazon

Linear Actuator

The PCB can control 1 or 2 actuators. I used these ones from ebay https://www.ebay.com/itm/334520303479

Build Instructions

Insert and solder components into the PCB matching the labels on the PCB front silkscreen. There are a few items to be aware of.

Glass fuse clips are use to hold the timer spade blades in place. Before soldering them in, beak off and discard the small end tab. Gradually bend the fuse holder sides in usind needle nose pliers. Ensure both sides touch each other and are centered. A few extra clips are inluded if you break one.

The two small transistors in the center of the board are not labled on the silkscreen. Ensure the VP3203N is on the left and the 2N7000 is on the right

Make sure you get the LED polarity correct. The long leg of the LED is positive and should be away from the flat side of the silkscreen symbol.

Polarity Swap - Should not be needed!

The timer poliary can be swapped by cutting 2 traces and adding 2 jumpers. Some older models of this timer had the polarity reversed, but I don’t believe this version is even sold anymore.
