This is one of those spontaneous projects that just happened. I wanted to try a surface mount project with a new micro USB connector I'd ordered, and this illuminated coaster type thing is the result.
I chose to use 1206 surface mount components because they are a reasonable size to solder with an ordinary iron bit. It's actually quite straightforward to put together, although I did mess up a couple of solder joints slightly by not heating the component and pad simultaneously. But it was an easy fix to reflow them and a valuable lesson in proper surface mount soldering technique.
I like the way the light shines through from below, so I may consider getting some PCBs made with no solder resist and a black screen print for the logo. I've not decided the colours yet.
Here's a link to the connectors I bought from aliexpress.
