Enclosure experiments

A project log for Impact

Millions of young athletes get concussions each year and 50% go undiagnosed, leading to brain injury. Impact detects these events early.

If this thing is going to be stuffed in helmets or other equipment, it needs some kind of enclosure to protect the electronics from moisture and dirt. I used a material from Smooth-On called XTC-3D to finish a 3D print recently (which is what that material is designed for), and I think it may work for coating electronics too.

I tried it on a test PCB with no parts populated, since I don't want to pot the one that I'm hacking on, since I need to be able to probe traces and pads. I know that there are potting materials made specifically for electronics, but this stuff is pretty easy to get, a little bit goes a long way, so it's cheap, and we'll see if it works well.
