Changing Bit by Bit
A new contest challenges people to use micro:bit computers to solve problems.
Could you use your computing skills to aid the fight against illegal animal hunting? How about tackling ocean pollution or monitoring animals under threat of extinction?
A new global challenge called Do Your Bit aims to get young people using their computing creativity to solve real-world problems. It’s being run by a partnership involving the BBC’s micro:bit computer, the technology company ARM and a campaign called World’s Largest Lesson, and it's aimed at people aged 10 to 16. It kicks off on 16 September.
The contest in 2019 is based on two Global Goals: to protect life on land and under the water. To take part, young people first choose a problem that affects them and their community, then design something involving the micro:bit computer that could help to tackle that problem.
Participants need to write up to 500 words about the problem and their solution, as well as providing a photo of their drawn plans or a hex file of their prototype code (编码), plus any other photos and videos showing what they’ve done.
This is the second micro:bit Global Challenge to be held. In 2018, the contest's winning designs included a homemade thief alarm, a classroom health monitor, a food-waste watcher and a device to remind people to sit up straight.
The deadline for entering the challenge is 28 February 2020: the winners will be announced the following month.

Like many parts of modern life, you can go digital when it comes to food scales (秤). If you want digital scales with an LCD display, then obviously you’ll need batteries which can run out at the most inconvenient of times. But the advantages of digital scales are many, including an accurate button which allows you to instantly remove the weight of an empty bowl, so you don’t need to do any maths calculations (计算). Mechanical (机械的)scales on the other hand have a pleasingly old-school reliability about them and undoubtedly add a touch of the style of the past to any kitchen. Read on for our top picks of mechanical scales, and digital scales, and balance scales.

A backlit display is an attractive feature. In addition to its good looks, it has an oversize digital display that is easy to read.

DM traditional cast iron balance kitchen scales
Cooking and baking isn’t all about time efficiency. It’s also about memories and the simple enjoyment of doing something that connects you.
MF 3-in-1 digital scales
We love the one that makes life easier by performing many functions. One part is a traditional balance, one part is a mixing bowl, and one part is a measuring pot, and the grade of the bowl itself allows accurate measurement of the liquid.
There are plenty of good reasons to prepare the best kitchen scales for your kitchen set up. More importantly, the sense of loss because of inaccuracy can be avoided. If you’ve got young kids, using scales is also a great way to add to their knowledge of weights and measures and to do some basic maths with them.
