Big Shot DIY Camera (£60)
This build-it-yourself digital camera gives you a 3MP sensor, a flash, a 1.4in LCD screen, USB connection and the ability to shoot regular, stereoscopic 3D and panoramic photos through a twistable lens wheel. There’s a rechargeable lithium polymer battery, but if that runs dry when you’re out shooting you needn’t worry: a handcrank can be used to top it up using good old-fashioned elbow grease.
A perfect stocking filler for inveterate tinkerers, Sugru is a self-setting rubber that can be moulded into any shape and will bond with everything from glass to wood to metal. It's flexible when it cures, and is both waterproof and electrically insulating. You can use it for anything from sealing engine parts to shock-proofing a camera – think of it as Silly Putty for grown-ups.

Makey Makey (£40)
Turn any old junk into a keyboard, mouse and joystick with this Arduino-based controller – just attach the alligator clips onto the objects of your choice, plug it into your PC via USB and tap away to your heart's content. Want to play Super Mario Bros with a twig? Or turn a banana into a piano? Go right ahead.
DJI Naza F450 Quad drone kit (£320)
2013 is the year of the drone, and what better way to see it out than by making your own? This easy-to-assemble kit provides you with your very own quadrotor, complete with the Naza V2 Flight Controller for easy take-off and improved maneuverability, including automatic course deviation compensation and GPS. Bear in mind that you'll need a radio transmitter and receiver for RC control – which will add around £200 to the total price.
