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]
It might not print it big, but the Form 1 High-Res 3D Printer ($3,300) can print nearly anything you can imagine in exquisite detail. Using high-end stereolithography technology, the Form 1 can construct details as small as 300 microns, and can print objects up to 4.9" x 4.9" x 6.5" in size. The included Form Software lets you start with .stl files and finalize your design, ensuring that every detail is there, just the way you designed it.
Some new product ideas are cool, and some are downright crazy — but it's the ones that are a little of both that often turn out the best. Take the Electree ($200 and up) for example. This sculpture/gadget is shaped after a bonsai tree, but instead of leaves it sports solar panels on its branches. And what does it do with all the energy it collects? It charges an internal battery that you can then use to charge your phone or tablet. Wirelessly, even, if you'd like. It surely beats the "garden" of wires you deal with now.
How to share your Instagram photos with friends without passing around your phone or tablet seems to be one of the hottest questions of the year. Projecteo ($25) thinks it has the answer — or more specifically, is the answer. This pint-sized projector uses an internal LED to project your photos, which have been printed onto 35mm film and cut into wheels, onto any wall you can find. To change wheels, simply pull out the current batch, slide in the next, and relish the quiet groans that haven't been heard since the traditional family photo slideshow fell by the wayside.
The number of awesome audio apps seems to grow by the day — yet getting your real-world gear to interface with your devices still requires messy dongles. Or at least it did. The Fender Squier USB Stratocaster Guitar ($200) sports a built-in mini-USB connector that lets you hook directly into your iDevice, Mac, or PC, as well as an onboard headphone jack with volume control. Of course, it's still a Strat, so you can also plug it into any amp and rock out the old fashioned way — the choice is yours.
