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.
PowerBoost 1000 Charger – Rechargeable 5V Lipo USB Boost @ 1A – 1000C: PowerBoost 1000C is the perfect power supply for your portable project! With a built-in load-sharing battery charger circuit, you’ll be able to keep your power-hungry project running even while recharging the battery! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects. Read more.
PiTFT Plus Assembled 320×240 2.8″ TFT + Resistive Touchscreen: Is this not the cutest little display for the Raspberry Pi? It features a 2.8″ display with 320×240 16-bit color pixels and a resistive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top! Read more.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

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.
