The Contraption is a 3D printed enclosure that turns a QRP radio + batter + antenna into a handheld HF radio. It's a little ridiculous, but really a lot of fun!
More details: hamradioduo.com/the-contraption-preview-release-of-3d-print-files
The files are available now for anyone who wants to try it on their own 3D printer. We will continue to provide the files for free for those who wish to print their own and will need to supply your own QRP radio, battery, antenna, 3D paddles, and cables.
Disclaimer: please enjoy this project at your own risk. Mike broke his favorite paddle already. Due to the nature of it, it is possible if not even likely that you drop something and break it. Also, as always use caution when playing radio outside – don't walk in front of cars when pedestrian mobile, always be cautious of power lines, etc.
