and the best way to get into making boxes is get an electronic starter kit and just build some of that shit.. then build wireless mics etc.. u can get them really small once you get good it's all about learning so just start small and build up you dont always need to build boxes.. me and my friend built a tone decoder to steal ppls pins to their alarms there is no limit to what ya can do
