The most tiniest 555 timer board available!

A fellow maker said he'd love to build a board with the BGA version of the classic 555 timer. I took that as a hint to develop one, and here it is, the FemFemFemto. I challenge you to solder this and then wear it with pride, it contains a loop for attaching to a necklace, bracelet or keychain.

All design files will be released as OpenSource shortly.

1 10uF tantalum capacitor
2 0402 LEDs (You can choose the colours!)
2x SR521 battery connector (no batteries are included due to shipping restrictions)

Kapton tape is useful to help keep the solder paste away from the gold decoration.

Why FemFemFemto?

Fem is 5 in Swedish, the language of my country. Femto is a very small SI Unit Prefix. Wikipedia article. Therefore FemFemFemto means a very small 555.
