We have created a free how guide to create your own manual firing system for your next backyard fireworks show. It is easy to make, and is much more secure than the current imported wireless systems that are currently on the market. These plans were written in 2011, and the prices reflect such. If you want to make a system of your own, go to the Download page and make your own system today. We still have some breakout boards that we are making available while they last. Use the Purchase link to get pricing (shipping will be calculated after you contact us) or link to our active Ebay listings to buy breakout boards.
