The Airsoft Community always search for realism and optimal performance.When the performance and/or the realism in your AEG1 aren’t enough you turn to modifications toimprove the weapon. But to manufacture such modifications isn’t that easy, hence you turn tocompanies that are specialized in creating such devices.The goal with this project is to create a prototype of a modification called “Programmable MOSFET”and targets optimization of the electrical components within the AEG. This means that you digitalizethe control of your AEG thus entails new functions and more stability to the system that isn’t possiblewith its mechanical predecessor.A prototype has been manufactured and programmed with functions according to requirementspecificationsthen it was tested on an airsoft-gearbox with rewarding results. The resulting prototypeis used as the basis for a final product that it is possible to base a business on.
