Whether it is motivated by a dream of superhuman strength courtesy of a mech suit or of mobility for those with impaired muscle function, the powered exoskeleton exerts a curious fascination among engineers. The idea of a machine-augmented human body achieving great things is thwarted though by the difficulty of the task, actuators and power

There’s something seriously wrong with the Arduino walkie-talkie that [GreatScott!] built. The idea is simple: build a wireless intercom so a group of motor scooter riders can talk in real-time. Yes, such products exist commercially, but that’s no fun at all. With a little ingenuity and a well-stocked parts bin, such a device should be easy to build

Persistance of vision is a fun feature of the human visual system, which allows us to blink a bunch of spinning LEDs at the right time to spell out messages that appear to hang in the air. [TN_Inventor] took a stab at his own POV build, using an old desk fan as a base. The initial

Instant ramen, the favoured repast of the impecunious would-be tech genius! It’s cheap, of dubious nutritional value, and it only takes a minute to cook. But what if you are in the creative Zone to the extent that five minutes to boil water is too much? For that you need an automatic ramen cooker, which

Fish are easy to keep as pets, requiring little more than regular feeding to keep them happy in the short-to-medium term. If you’re going on holiday, it can be nice to know that your pets are being taken care of, but finding someone to take on the chore can be hard. [Trevor_DIY] doesn’t need to

For [Turbo Conquering Mega Eagle], the question was simple: Do I spend 20 minutes slaving away in front of a bandsaw to cut a bunch of short brass rods into even shorter pieces of brass rod? Or do I spend days designing and building an automatic cutoff saw to do the same job? The answer is obvious. It’s

We’ve heard of beer pong, but we’re not sure we’ve heard of wine pong. And certainly never wine pong automated with a ping pong ball throwing robot like this one. There’s not a huge amount of detail available in the video below, and no build log per se. But [Electron Dust] has a few shots in the

It can be controlled through logic levels to set the speed and the direction of the rotation of CC brushed motors and stepper motors; outputs have LEDs indicating the rotation direction. The circuit board we are presenting this time is based on the dual-bridge driver L298N, in a traditionally mounted version in a Multiwatt container
