DIY 3d Printed Dew Controller
By: Vlad Fedosov
Having an evening of observing ruined by you objective dewing up is never fun. Unfortunately spending over $100 on a dew controller is never fun ether. After doing a bit of research on-line I was able to put together my own dew controller that works just as well as the commercial units costing over $100. This unit is compatible with any commercial dew heater straps. It is made to control two separate straps but this design can easily be adapted to do more straps.
To begin this project I did research online at a variety of web sites and forums that gave me the basic info of how to get a working dew controller in a way that is not overly complicated and relatively inexpensive. The basic components needed to make this dew controller are outlined here:
The above does not include a project box as I own a 3d printer and I decided to make a box that is 100% customized for this applications and is ready to have all the electrical components installed. Here is a guide on the basic assembly of the dew controller:
Remove the 4 screws. Remove the green plug and knob as well as knob nut.
Take out the electronics out and install into enclosure.
Wire as shown.
It takes very basic electronics skills and a bit of tools to make one of these at home. If you enjoy a DIY project and/or cannot get yourself to spend over $100 on a commercial dew controller then this is the solution for you! If you would more info or have questions about the project feel free to email me. I also have a few sets of all the components needed to make one of these and can 3d print an enclosure if you want a really easy way of making one of these. Email: firstname.lastname@example.org
