A work of art is appreciated for its own sake and we will never tire of seeing stunning circuits from microscopic dead-bugs to ornate brass sculptures. We also adore projects that share the tricks to use in our own work. Such is the case with [Jiří Praus] who made some jewelry and shared his templates so we try this out ourselves.
The materials include brass wire, solder, and surface-mount LEDs. Template design expects a 1206 light, so if you step outside that footprint, plan accordingly. The printable templates are intuitive and leverage basic wire jewelry making skills. Some good news is that flashing LEDs are available in that size so you can have an array of blinkenlights that appears random due to drifting circuits. Please be wary with RGB lights or mixing colors because red LEDs generally run at a lower voltage and they will siphon a significant chunk of a coin-cell’s power from a competing green or blue. How else can these be personalized?
[Jiří]’s charms are just the latest of circuits that capture our eyes and tickle our ears.

It’s worth a second post tho. These are awesome.
It was a fun project and the templates helped a lot, I personalized mine by making it into a spinning top, next step should be some long exposure photography, :)

Excellent job sticking to the base materials and putting your own twist on it.
Where is the battery promised in the title?
It wasn’t until I followed the link that I realised that the photo at the top here does actually have the battery present (it’s a split photo across the diagonal – top left with the battery, bottom right without) – they’re using CR2032 (or similar) cells.
I saw Jiří Praus in person at Maker Faire Prague and his whole stand was treasure!
