Bitluni has spent years pushing DIY electronics further than most people expect. His earlier clusters packed a few hundred small RISC-V chips onto compact boards and proved they could outperform a regular desktop processor on certain tasks while using almost no power. That success led him to ask what would happen if he kept scaling. The answer sits on his bench now: an ultra cluster built around 8,192 individual microcontrollers running at 100 MHz, managed by 256 larger controller chips.

Summer stretches days longer and pulls people toward trails, water, and full days outside. A watch that handles knocks, stays readable in bright light, and runs for extended stretches without a charger becomes more than nice to have. The Apple Watch Ultra 3, priced at $699.99 (was $799), fills that role for many who want one device to cover serious activity and everyday tracking.

Nothing just rolled out the Phone 4b with a clear focus on giving people longer battery life and reliable daily performance at a price that stays practical. The new model blends design ideas from recent Nothing phones into a single device that feels familiar yet refined in the areas that matter most for real use.

Liel Farhat enjoyed a sailing trip with friends near Athens when her iPhone 16 Pro ended up in the sea during a swimming stop. She had set the device down to take a photo. It slid into a net on the yacht and disappeared beneath the surface.

Over the weekend, visitors wandering along Australia’s Forrest Beach, just north of Townsville, came across something pretty unusual. A host of shining, metallic spheres began washing up on the beach, attracting attention due to their unique shapes and fittings in an area of the coastline where little else happens. Six of these appeared on Friday, Saturday, and Sunday, each almost twice the size of a basketball.
