A DIY project for your pleasure. This project began over a year ago as a very inexpensive option to the purchased button boxes available. However after a series of problems the project has changed direction for a more powerful and simpler option. In the end it cost a little more money but still came in at half the price of retail. In this video Cristy talks to Shaun about how he went about the project, the problems encountered, and how it turned out in the end.
