Robert writes in to point out the P2P Radio Broadcaster –
Remember those little pirate radio stations in the 80’s? Enter the p2p radio broadcaster by Juan Esteban Rios, this little device provides a means to transmit audio content to local radio receivers, and by having the listeners act as peers, the network can be expanded as much as it needs to. Overlooked communities in remote areas or poor urban environments can now take back the radio airwaves. The device is also powered by handcranking it, 1 minute for every 40 minutes of airtime.
