Retrofitted Retro Radio

In a world full of products that are only used for a brief time and then discarded, it gives a lot of us solace to know that there was a time when furniture was made out of solid wood and not particle board, or when coffee makers were made out of metal and not plastic. It’s hard to say exactly what precipitated the change to our one-time-use culture, but in the meantime there are projects that serve to re-purpose those old, durable products from another time so that they can stay relevant in today’s ever-changing world.

Sniffing Bluetooth Devices With A Raspberry Pi

Hackaday was at HOPE last weekend, and that means we got the goods from what is possibly the best security conference on the east coast. Some of us, however, were trapped in the vendor area being accosted by people wearing an improbable amount of Mr. Robot merch asking, ‘so what is Hackaday?’. We’ve all seen The Merchants Of Cool, but that doesn’t mean everyone was a vapid expression of modern marketing. Some people even brought some of their projects to show off. [Jeff] of reelyActive stopped by the booth and showed off what his team has been working on. …read more
