+ | == Sourcing == | ||
+ | For my initial experiments I want to use recycled glass. I have lots of mirror scraps, some blown glass bottles, and a glass tabletop. I need to solve a few problems: | ||

+ | * Removing the silvering on the mirrors, | ||
+ | * Blown versus float glass, | ||
+ | * Smashing the glass into frit, | ||
+ | * Particle size, | ||
+ | * Wash versus non-wash. | ||
+ | * Fusing the glass into solid chunks. | ||
+ | * Temperature profile, | ||
+ | * Flux. | ||

+ | The join will be the weak part. I would like to fuse the two bits of glass into one, however that would require around 800 degrees celsius, which would destroy the electronics. | ||

Some of the cooler options for electronics inside the sphere require microcontrollers and flash storage, which would have their effective lives extended with some radiation shielding. I'll use a leaded potting compound (if it exists), or lead sheets wrapped around the electronics. | Some of the cooler options for electronics inside the sphere require microcontrollers and flash storage, which would have their effective lives extended with some radiation shielding.
