Like a lot of parents, [justbennett] ‘s kids like to play rocket and spaceship command. His kids’ imagination-assigned controls kept shifting from this LEGO to that banana to the dog’s tail, so [justbennett] did what he had to do: makethis Dad-built rocket control module for them.
The module supports all of the vital sub-modules required for rocket and spaceship administration. There is a launch status indicator, an acceleration vector resonator (AVR), and a com-link. He used mostly parts on hand, and the Arduino count is zero. He built a NASA-grade Plexiglas enclosure to avoid juice box incidents. The two pieces are connected with aluminum angle bar so that he can make repairs or modifications.
The analogue joystick was a thrift store find. [Justbennett] wired the trigger and thumb buttons up as the AVR which activate a recycled PICAXE 08M project of his. The PICAXE senses the button pushes to flash an LED and play an ascending or descending tone. Long-pressing one button will result in an explosion noise as you might expect.
The launch status indicator is a potentiometer wired to a second PICAXE and three LEDs that light up in sequence. In the future, [justbennett] intends to add haptic feedback with a tiny vibration motor. The com-link packet messaging system is a Radio Shack recording module and two big, tempting buttons. The control module ships with a message from Star Command that explains the controls.
