Have some data that you need protected? Store it on an ioSafe Solo G3 Hard Drive ($400). This external USB 3.0 drive is both fireproof — up to 1550º for 30 minutes — and waterproof — down to 10 ft. for up to 72 hours. It's also nearly silent, compatible with Kensington locks and padlocks, and includes backup and encryption software. But the real kicker is the ioSafe Data Recovery Service, which provides a one-time data and hardware recovery, no questions asked.
Combine the joy of making music with the nostalgia of a classic arcade machine with Pianocade ($250-$325). This powerful synthesizer is designed to sound, look, and feel like a vintage arcade game, offering a 128-note range, 5-pin and USB MIDI connectors, and either one or two octaves worth of buttons. Feel like customizing your own? You can buy the electronics by themselves for $100.
Whether you're just getting interested in electronics or want to pass on your knowledge to others, these Technology Will Save Us DIY Kits (£10-£85; roughly $16-$135) are a great place to start. Each kit comes complete with everything — or at least nearly everything — you need to build a simple electronics project, from a sensor that tells you when your plant needs water to a basic synthesizer. If you're looking to dive in head first, though, you might want to start with the soldering and Arduino kits, which will give you a solid base to build on. [Scouted by Luke]
