Wimbledon 2019: IBM’s Slammtracker AI Technology Heralds The Demise Of The Human Player

July 8, 2019 by 4 Comments

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 ball, analyses player gestures, crowd cheers/booing but can’t yet discern the more subtle player behaviour such as serving an ace or the classic John McEnroe ‘smash your racket on the ground’ stunt. Currently a large number of expert human side kicks are required for recording these facets and manually uploading them into the huge Watson driven analytics system.

Phone apps are possibly the best places to see the results of the IBM Slammtracker system and are perfect for the casual tennis train spotter. It would be interesting to see the intrinsic AI bias at work – whether it can compensate for the greater intensity of the cheer for the more popular celebrities rather than the skill, or fluke shot, of the rank outsider. We also wonder if it will be misogynistic – will it focus on men rather than women in the mixed doubles or the other way round? Will it be racist? Also, when will the umpires be replaced with 100% AI?

Finally, whilst we at Hackaday appreciate the value of sport and exercise and the technology behind the apps, many of us have no time to mindlessly watch a ball go backwards and forwards across our screens, even if it is accompanied by satisfying grunts and the occasional racket-to-ground smash. We’d much rather entertain ourselves with the idea of building the robots that will surely one day make watching human tennis players a thing of the past.

New Contest: Beautiful Hardware

July 2, 2019 by 13 Comments

We all have awesome hardware projects to show off. Great photos of them are how you unlock the excitement others see in your work. Whether you’re using a DSLR or the camera in your smartphone, it’s not difficult to capture an amazing picture of the project you pour so much effort into. We want you to unleash your photography skills for the Beautiful Hardware contest. Show us your epic hardware photos and win prizes.

The Skeleton Watch by Mile is a great example of superb photography. Excellent framing, focus, and color make it great.

The only real barrier between us and superb hardware photos is having an eye for framing your shots, and a few simple tricks to get everything else right. Think about good lighting, shooting with an interesting background, framing off to the side and at an angle (as just one example) for more interest, and spending a few moments with an image editor to complement what the camera captured. With this contest, we want you to take those tricks for a spin on your own workbench.

Lee Wilkins put together a simple guide to get you going with spectacular hardware photography. From the basics of photography and the tricks used for making product hype photos, to capturing great images of LEDs and getting the colors just right, this is a comprehensive quickstart. There’s even a collection of great examples to strive for.

There are three top prizes of $100 cash waiting for you. Just start a new project on Hackaday.io and upload the finest photos you can take of some fun hardware. In the left sidebar of that project use the “Submit project to…” menu to enter it in the Beautiful Hardware contest.

Finally, An Open Source Multimeter

June 20, 2019 by 18 Comments

For his Hackaday Prize entry, [Martin] is building an Open Source Multimeter that can measure voltage, current, and power. It’s an amazing build, and you too can build one yourself.

The features for this multimeter consist of voltage mode with a range of +/-6V and +/-60V. There’s a current mode, basically the same as voltage, with a range of +/-60 mA and +/-500mA. Unlike our bright yellow Fluke, there’s also a power mode that measures voltage and current at the same time, with all four combinations of ranges available. There’s a continuity test that sounds a buzzer when the resistance is below 50 Ω, and a component test mode that measures resistors, caps, and diodes. There’s a fully isolated USB interface capable of receiving commands and transmitting data, a real-time clock, and in the future there might be frequency measurement.

This build is based on the STM32F103 microcontroller, uses an old Nokia phone screen, and unlike so many other multimeters, this thing is small. It’s very small. More than small enough to fit in your pocket and forget about it, unlike nearly every other multimeter available. There’s one thing about multimeters, and it’s that the best multimeter is the one that you have in your hands when you need it, and this one certainly fits the bill.

The entire project is being written up on hackaday.io, there’s a GitHub repo for all the hardware and software, and there’s also a video demo covering all the features (available below). This is a stand-out project, and something we desperately want to get our hands on.

These Projects Bent Over Backward To Win The Flexible PCB Contest

June 19, 2019 by 7 Comments

Back in March, the call went out: take your wiggliest, floppiest, most dimensionally compliant idea, and show us how it would be better if only you could design it around a flexible PCB. We weren’t even looking for a prototype; all we needed was an idea with perhaps a sketch, even one jotted on the legendary envelope or cocktail napkin.

When we remove constraints like that, it’s interesting to see how people respond. We have to say that the breadth of applications for flex PCBs and the creativity shown in designing them into projects was incredible. We saw everything from circuit sculpture to wearables. Some were strictly utilitarian and others were far more creative. In the end we got 70 entries, and with 60 prizes to be awarded, the odds were ever in your favor.

Now that the entries have been evaluated and the winners decided, it’s time to look over the ways you came up with to put a flexible PCB to work. Normally we list all the winners in our contest wrap-ups, but with so many winners we can’t feature everyone. We’ll just call out a few of the real standout projects here, but you really should check the list of winning projects to see the full range of what this call for flexibility brought out in our community.

New Contest: Connected World

June 18, 2019 by 5 Comments

We’re on the lookout for the most interesting connected projects, things that communicate wirelessly to do something clever. Show us your creations and you can win the Connected World contest.

Chances are you’ve already been automating the world around you with wireless connections. This could be as simple as WiFi, or as convoluted as systems separated by miles yet connected via line-of-site laser communications. It could be 433 MHz wireless modules, or Bluetooth steering wheel control for your miniature robot. We’d really like to see a washing machine with a satellite uplink but we’d better be careful what we wish for.

We’ll pick the top 20 entries based on your creativity, execution, functionality, and how well you tell the backstory. Each will receive a free PCB coupon for up to $50 from OSH Park. Additionally, we’ll award the title of Best Project, Best Aesthetic, Best Documentation, and Best Media to four entries and give each a $100 Tindie gift card.

Don’t delay, put your project up on Hackaday.io and use the dropdown box on the left sidebar to enter it in the Connected World contest.

2019 Cornell Cup Winners Include Autonomous Boat, Flapping UAV, And Leaping Rover

May 15, 2019 by 5 Comments

For college-aged engineers and designers, finding a problem they’re truly passionate about early on could very well set the trajectory for an entire career. This is precisely the goal of the Cornell Cup, a competition that tasks applicants with solving a real-world problem in a unique and interesting way. From what we saw this is definitely working, as teams showed up with ornithopter-based quadcopters, robotic dinghies, forest fire sniffers, and high-jumping rovers.

With such an open ended approach, individual entries have a tendency to vary wildly, running the gamut from autonomous vehicles to assistive technology. No team feels pressured to pursue a project they aren’t truly invested in, and everyone’s the better for it.

Given such lofty goals, Hackaday was proud to sponsor the 2019 Cornell Cup. Especially as it so closely aligns with the product design focus of this year’s Hackaday Prize. Designing something which solves a real-world problem is definitely part of the formula when the goal is to reach large scale production. And after seeing the entries first-hand during the Finals at Kennedy Space Center, we think every one of them would be a fantastic entry into the Hackaday Prize.

I don’t envy the judges who ultimately had to narrow it down to just a few teams to take home their share of the nearly $20,000 awarded. Join me after the break for a closer look at the projects that ended up coming out on top.

Flexible PCB Contest Round Up

April 15, 2019 by 19 Comments

The 2019 Hackaday Prize, which was announced last week, is very much on everyone’s mind, so much so that we’ve already gotten a great response with a lot of really promising early entries. As much as we love that, the Prize isn’t the only show in town, and we’d be remiss to not call attention to our other ongoing contest: The Flexible PCB Contest.

The idea of the Flexible PCB Contest is simple: design something that needs a flexible PCB. That’s it. Whether it’s a wearable, a sensor, or a mechanism that needs to transmit power and control between two or more moving elements, if a flexible PCB solves a problem, we want to know about it.

We’ve teamed up with Digi-Key for this contest, and 60 winners will receive free fabrication of three copies of their flexible PCB design, manufactured through the expertise of OSH Park. And here’s the beauty part: all you need is an idea! No prototype is necessary. Just come up with an idea and let us know about it. Maybe you have a full schematic, or just a simple Fritzing project. Heck, even a block diagram will do. Whatever your idea is for a flexible PCB project, we want to see it.

To get the creative juices going, here’s a look at a few of the current entries

The Flexible PCB Contest goes through May 29, so you’ve got plenty of time to get an idea together.
