This is a very budget tablet, but if you want a slate that works and runs Android for only £34.30 on Amazon this is ideal.

Great as a destroyable gift for children.

Sugru is essentially posh putty that’s now being sold with magnets in a kit. The D357 battery sized magnetic discs let you marry together anything their magnetism can support. Bike lights are the most obvious use, but it’s really pretty limitless up to a certain weight. And they’re only £10 for a set of four.

Home: Lumen smartbulb

Control your light's colour, brightness and timings from your mobile. The Lumen smartbulb uses Bluetooth, so you won’t need to fork out for that Wi-Fi hub like on the Philips Hue. That means the price can be brought down but it also means you won’t be able to control the lights from anywhere in the world. But with the ability to set timers on the Lumen smartbulb you shouldn’t need to anyway. You can pick one up for £40 now.
