Issues & Camp Impact

Ekoparty 2025 Badge note

exposed electronics caution · primary repository · documented

The repository manual warns that the badge has exposed electronics and can short if placed on conductive material, even when switched off because the battery keeps the charge-management area powered.

The safety note belongs in the record because it affects handling of the physical artifact.
