Halifax Makerspace was invited by our local library to an afternoon of tech and crafting. After our plans of an intro to soldering course fell through (no soldering permitted due to fire regulations), we were forced to be a bit more creative. For our part of the program, we wanted:
What we decided on was an acrylic ornament in two pieces, with an LED in the base lighting the ornamental part. Copper tape would make the connection between a lead of the LED and a button cell battery.
You could do any size batch of these for a makerspace open house, a Cub Scout troop activity, for everyone on a Christmas list, wedding favours, or just cut one for yourself.
Materials (Total cost for us: about $0.25-0.30 per ornament)
We decided on a reusable generic base, in case we wanted to do a similar events for other holidays in the future. Features of the base:
It took some testing to get the battery hole exactly right. We wanted to make sure it press fit in place (with a LED lead and copper foil), and that it didn't press in so far that it came out the bottom.
