The Dyson Awards Definitely Do Not Suck

Named after British inventor James Dyson of cyclonic vacuum cleaner fame, the Dyson Awards are presented annually to current and recent students of engineering, industrial design, and product design, regardless of age. Students from 27 countries work alone or in groups to describe their inventions, which are then judged for …read more

Wimbledon 2019: IBM’s Slammtracker AI Technology Heralds the Demise of the Human Player

Whilst we patiently wait for the day that Womble-shaped robots replace human tennis players at Wimbledon, we can admire the IBM powered AI technology that the organisers of the Wimbledon tennis tournament use to enhance the experience for TV and phone viewers.

As can be expected, the technology tracks the …read more

Flex PCBs Make Force-Mapping Pressure Sensor for Amputee

What prosthetic limbs can do these days is nothing short of miraculous, and can change the life of an amputee in so many ways. But no matter what advanced sensors and actuators are added to the prosthetic, it has to interface with the wearer’s body, and that can lead to …read more

New Contest: Flexible PCBs

The now-humble PCB was revolutionary when it came along, and the whole ecosystem that evolved around it has been a game changer in electronic design. But the PCB is just so… flat. Planar. Two-dimensional. As useful as it is, it gets a little dull sometimes.

Here’s your chance to break …read more

3D-Printed Tourbillon Demo Keeps the Time with Style

It may only run for a brief time, and it’s too big for use in an actual wristwatch, but this 3D-printed tourbillon is a great demonstration of the lengths watchmakers will go to to keep mechanical timepieces accurate.

For those not familiar with tourbillons, [Kristina Panos] did a great overview of these mechanical marvels. Briefly, a tourbillon is a movement for a timepiece that aims to eliminate inaccuracy caused by gravity pulling on the mechanism unevenly. By spinning the entire escapement, the tourbillon averages out the effect of gravity and increases the movement’s accuracy. For [EB], the point of a …read more

Geared Cable Winder Keeps Vive Sync Cable Neatly Wound

Long cables are only neat once – before they’re first unwrapped. Once that little cable tie is taken off, a cable is more likely to end up rats-nested than neatly coiled.

Preventing that is the idea behind this 3D-printed cable reel. The cable that [Kevin Balke] wants to make easier to deal with is a 50 foot (15 meters) long Vive lighthouse sync cable. That seems a bit much to us, but it makes sense to separate the lighthouses as much as possible and mount them up high enough for the VR system to work properly.

[Kevin] put a good …read more

7-Segment Display is 3D Printed and Hand Cranked

[Peter Lehnér] has designed a brilliant 7-segment flip-segment display that doesn’t really flip. In fact, it doesn’t use electromagnets at all. This one is 3D printed and hand cranked. It’s a clever use of a cam system to set the segments for each digit (0-9) makes it a perfect entry in the Hackaday 3D Printed Gears, Pulleys, and Cams contest.

We find the nomenclature of these displays to be a bit confusing so let’s do a quick rundown. You may be most familiar with flip-dot displays, basically a dot-matrix grid of physical pixels that are black on one side and …read more
