The BYTE Is The Grand Prize Winner Of The 2020 Hackaday Prize

November 7, 2020 by 13 Comments

The BYTE, an open-source mouth-actuated input device for people with physical challenges has just been named the Grand Prize winner of the 2020 Hackaday Prize. The award for claiming the top place and title of “Best All Around” in this global engineering initiative is $50,000. Five other top winners and four honorable mentions were also named during this evening’s Hackaday Prize Ceremony, held during the Hackaday Remoticon virtual conference.

This year’s Hackaday Prize focused on challenges put forth by four non-profit partners who have first hand knowledge of the problems that need solving as they work to accomplish their missions. These organizations are Conservation X Labs, United Cerebral Palsy Los Angeles, CalEarth, and Field Ready. Join us below for more on the grand prize winner and to see the Best in Category and Honorable Mention winners from each non-profit challenge, as well as the Best Wildcard project.

Over $200,000 in cash prizes have been distributed as part of this year’s initiative where hundreds of hardware hackers, makers, and artists competed to build a better future. Continue reading “The BYTE Is The Grand Prize Winner Of The 2020 Hackaday Prize” →

DIY Scalar Network Analyzer

December 25, 2019 by 1 Comment

[Steven Merrifield] built his own Scalar Network Analyzer and it’s a beauty! [Steve]’s SNA has a digital pinout matching a Raspberry Pi, but any GPIO could be used to operate the device and retrieve the data from the ADC. The design is based around a few tried and true chips from Analog Devices. He’s taken some care to design it to be nice and accurate which is why he’s limited it to 1kHz to 30Mhz. We think it’s quite a fetching board once the shielding is in place.

We’ve covered network analyzers and their usefulness before. If you want to know how, for example, a mystery capacitor from your junk bin will respond to certain frequencies, a network analyzer could tell you. We’ve even taken a stab at hacking together our own.

There is more documentation on his website as well as some additional example curves. The board is easily ordered from OSHpark and the source code is available for review.

Listen To Your Feet, They Have A Lot To Tell You

December 22, 2019 by 8 Comments

[Umar Qattan] is in tune with his sole and is trying hard to listen to what it has to say.

At a low level, [Umar] is building an insole with an array of force sensors in it. These sensors are affixed to a flexible PCB which is placed in a user’s shoe. A circuit containing a ESP32, IMU, and haptic feedback unit measure the sensors and send data back to a phone or a laptop.

What’s most interesting are the possibilities opened by the data he hopes to collect. The first application he proposes is AR/VR input. The feedback from the user’s feet plus the haptics could provide all sorts of interesting interaction. Another application is dynamically measuring a user’s gait throughout the day and exercise. People could save themselves a lot of knee pain with something like this.

[Umar] also proposes that an insert like this could record a user’s weight throughout the day. Using the data on the weight fluctuation, it should be possible to calculate someone’s metabolism and hydration from this data.

Building A Limitless VR Desktop

December 21, 2019 by 44 Comments

[Gabor Horvath] thinks even two monitors is too little space to really lay out his windows properly. That’s why he’s building a VR Desktop straight out of our deepest cyberpunk fantasies.

The software runs on Windows and Android at the moment. The user can put up multiple windows in a sphere around them. As their head moves, the window directly in front grows in focus.  Imagine how many stack overflow windows you could have open at the same time!

Another exciting possibility is that the digital work-spaces can be shared among multiple users. Pair programming isn’t so bad, and now the possibility of doing it effectively while remote seems a little more possible. Even pair CAD might be possible depending on how its done. Imagine sharing your personal CAD session on another user’s screen and seeing theirs beside yours, allowing for simultaneous design.

Overall it’s a very cool tech demo that could turn into something more. It makes us wonder how long it is before tech workers on their way to lunch are marked by a telltale red circle on their face.

Replace Your Smartphone With These Arcane Amulets

December 19, 2019 by 17 Comments

It’s hard not to feel the constant pull on our limited attention from the very interesting rectangles in our pockets and packs. [Antoine Pintout] is fighting against it with three interesting pendants.

The three objects each have functions. Sablier, tells time, but rather than giving the numerals it vibrates on a set interval to give a relative sense of the passage. Boussole is a compass like device which doesn’t tell the cardinal directions. Instead it tells you which way to go in order to get to a pre-set location. The last, Sifflet, is a pager, but rather than sending a text it plays a melody reflecting the sender’s mood.

We love the look of the objects. The circuits are beautifully laid out and showcased in well machined brass cases. Small details abound; in Sifflet for example, the coil antenna is symmetrically presented with its own cutout in the board. Laying out a board is hard enough, but taking this much care in component placement easily doubles the time.

All the files and models are available,  though we’re not sure we possess the craftsmanship to reproduce these to the same standard.

A Nixie Radio Clock Fit For A Victorian Mad Scientist

December 17, 2019 by 11 Comments

[Ioszelos] built a nixie clock with a dizzying array of features.

Do you ever wish that you could log in to your clock from your phone and turn off your TV? We assume that [Ioszelos] did. The clock can also play MP3s and stream radio stations. It can record the indoor temperature, humidity, and barometric pressure. Did we mention it’s an FM radio too? We’re not sure, but we wouldn’t be surprised if there was a faucet hiding somewhere on the contraption.

A team effort shared between an ESP32 and Mega 2560 run the Rube Goldberg-like show. Custom boards were spun up to provide the control and voltages needed for the nixie tubes. The clock is constructed from machined plates and 3D printed files.

It all comes together in a steampunk reminiscent assembly. The glow from the RGB leds and nixie tubes combine to make an interesting visual effect. We’ve certainly never seen a clock quite like it before.

A LED Cube Designed For Easy Assembly

December 15, 2019 by 6 Comments

LED cubes are mesmerizing and fun, but they’re usually a pain to build. Not so with [burkethos]’s cleanly designed cube. 

Many cubes are put together in an elaborate sculptural style. Traditionally the leads of the LEDs are artistically bent and then hours are spent laboring over the future rainbow Borg cube. This build is more reminiscent of a motherboard or back plane design. The LEDs are surface mount units re-flowed onto a rake shaped PCB. At the base of each “rake” there’s a right angle male header. This is then soldered to base board which creates a reliable mechanical bond.

There are some downsides to this approach. For example, the PCBs occlude the LEDs at some viewing angles. However, this can be mitigated with careful placement in the room, or in one variation, mounting the cube at a different orientation so the rakes are horizontal rather than vertical.

Regardless, we appreciate this new take on an old project and can definitely see it having a more universal appeal than the kits that require a couple weeks of afternoons to finish.
