This page details how to make an automatic ice fishing jig or decoy spinner. There are other similar devices on the market such as the Pike Buster or Lindell Auto Jigger but they are very expensive, awkward to use or not powerfull enough for a decoy. The jigbuddy is contained in a single box and will run for a very long time using 4 D-cell batteries. It features a convenient on/off switch and adjustable delay knob to control the jig speed. I hope you enjoy the tutorial and best of luck with your next fishing adventure.

Required Tools

  1. 22 guage wire strippers
  2. Sottering Iron for connecting battery, switches and micro controller
  3. Drill and/or dremmel to cut relay and switch holes in project box
  4. Small screw-driver


  1. Project Box Modifications

    Use a dremmel or drill and cut all holes detailed in picture.

  2. Wiring Schematic
  3. Pro-Mini 5v Micro-Controller

         The control for the servo is done by a small open source mico-controller called an arduino. The arduino is very easy to program thru most computers using a usb cable. There are also lots of tutorials online that detail how to do this. For this project I used a smaller version of the arduino available thru adafruit, called the pro-mini. The pro-mini was ideal for this project because its small in size, costs less than a full size audrino but still has the required inputs and outputs. The pro-mini provides two important functions for the project. It controls the servo position thru pulse width modulation and it also reads the speed control kob position (10k pot) to provide an adjustable delay time before jigging the servo.  If you'd like to learn how to program the pro-mini or arduino, more tutorials can be found at adafruit. Example code for the project is posted below.

  4. Assembled Project Box

         Servo should be able to fit thru the servo hole in the box which means everything can actually be wired while outside of the box. This make wiring and assembly much easier. Make sure all wires have adequate length and then connect all components in the wiring schematic together.  When finished all compnonents can be placed in box and attached to case. The battery holder should go in last so you have room to install the servo and switches.

  5. Rattle Reel

         The last step is to drill a hole on the top back side of the project box for the rattle reel bolt. Slide bolt thru inside of box and install Rattle Reel. Tighten the rattle reel nut until the reel line has a small amount of drag.
