Build a ‘real’ Mars rover
Most ‘hobby’ mobile robots on the market are usually of the 2-, 4-, or 6-wheeled variety with no suspension or steering systems. Changes in direction are achieved by varying wheel-speeds – so-called skid or tank steering. Not this one.

How big is your Electronic Tech’s Carbon Footprint?
Everyone knows that gaseous emissions from fossil-fuel burning to bovine flatulence are the cause of global warming, right? Indeed they are, but less obvious causes of a high carbon footprint are becoming apparent. And your ‘Tech’ may be involved.

Rocket’s Return: The UK Space Launch Industry Then and Now
In 1971 the UK joined a very select group of countries by sending an artificial satellite into Earth orbit using a UK-built rocket. Then it gave up. Until now. Are we on the brink of starting again, this time launching from home soil?

New Constellations in the Sky
SpaceX has just launched 60 satellites into low Earth orbit as a test run for a future ‘constellation’ containing as many as 12000. Before that a CubeSat, KickSat-2 put 105 tiny ‘Sprite’ satellites into orbit. Isn’t Space too crowded already?

When Redundancy is a Good Thing
The recent crash of Ethiopian Airlines flight EA302 involving the latest version of the Boeing 737 airliner highlights how small changes in design can lead to a catastrophe. In this case, safety had become optional.
