Tool Time: What Actually Works
- Magnetic screwdriver: Prevents tiny screws from playing hide-and-seek
- Plastic spudger: Guitar picks work surprisingly well

2024's Game Changer: Solar Batteries Meet Sustainability
The EU's new Portable Battery Directive impacts replacement parts availability. Good news? Bio-based lithium batteries now last 15% longer. Bad news? Your 2010 Casio might need an adapter ring. It's like putting electric car tires on a Model T - doable, but requires some MacGyvering.
