Resin-in-resin: How to Make a Literal ‘Embedded’ Device #piday #raspberrypi @Raspberry_Pi

Via Resin.io

Resin.io does a lot of cool stuff. But if you had to say what we do in one sentence, it’s this: “resin.io enables you to safely deploy and manage fleets of embedded devices that you might not have physical access to.”

I’m a Solution Architect here, which means that part of my job is to show people exactly how resin.io works. Usually I do this in a very “real world” way by pointing webcams at devices located in our offices all around the world and then deploying code to them with a single git push. But I’ve always wanted a way to make this feel even more tangible than deploying to a fleet of Raspberry Pis that are thousands of kilometers apart. Something that people could really see and know for sure that resin.io just plain works.

A few weeks ago I realized how I could do it: I’d attach a display to a Raspberry Pi and encase the entire thing in a block of clear epoxy resin. The USB and Ethernet ports are filled in and the SD card slot is inside the solid block. Even when I carry it with me, it’s still accessible only remotely. It’s literally an “embedded” device.

I call it “resin-in-resin.”

  1. While this is a very nice looking project, I have a feeling that it could be VERY dangerous.
    Encapsulating is a very DANGEROUS thing. This is exactly what cause a few million Samsung 7s to be recalled.

    Batteries need to expand and often breath. At a bare minimum I would expect some material be added next to the battery than can compress, to allow the battery to expand. I’d also think about drilling a small hole into the area, to allow the battery to outgas.

    I did just notice on the original article at resin.io, that the author has realized the issue and warns against recreating as-is.
