For a current project, I needed to cast some electronics in epoxy resin. The process was eventually successful, but it did take 3 attempts to get it right.
The aim was to encapsulate a Neopixel ring and control electronics in epoxy and use this as an underwater macro ring light for my underwater camera.
This blog post is just going to detail the process I used and the mistakes made. Once I finish the ring light, I’ll make post about it.
