Premier space exploration disaster simulator, Kerbal Space Program, is fun to play with regular controls, but it can be improved with this DIY build that lets you launch ships with a giant red button.
Based on an Arduino Micro, this project gives you a small control panel with two buttons. The smaller green one toggles between minimum and maximum thrust and the red one launches or stages the rockets.
This completed version of the projects was made for £20 (~R318), which is pricey but, damn, we really want to press that button.
As you may have guessed this is a simple project that uses an Arduino to mimic a keyboard input. This isn’t necessarily a bad thing, it means that it can be adapted to other games, which makes the investment in hardware and time easier to swallow.
If you’d like to do just that, a full tutorial for this setup was uploaded to Instructables.
