Vinduino Water-Smart Farming – Now With LoRa!

October 25, 2018 by Roger Cheng 9 Comments

Our five rounds of Hackaday Prize 2018 challenges have just wrapped up, and we’re looking forward to see where the chips fall in the final ranking. While we’re waiting for the winners to be announced at Hackaday Superconference, it’s fun to take a look back at one of our past winners. Watch [Reinier van der Lee] give the latest updates on his Vinduino project (video also embedded after the break) to a Hackaday Los Angeles meetup earlier this year.

Vinduino started with [Reinier]’s desire to better understand what happens to irrigation water under the surface, measuring soil moisture at different depths. This knowledge informs more efficient use of irrigation water, as we’ve previously covered in more detail. What [Reinier] has been focused on is improving usability of the system by networking the sensors wirelessly versus having to walk up and physically attach a reader unit.

His thought started the same as ours – put them on WiFi! But adding WiFi coverage across his entire vineyard was not going to be cost-effective. After experimenting with various communication schemes, he has settled on LoRa. Designed to trade raw bandwidth for long range with low power requirements, it is a perfect match for a network of soil moisture sensors.

In the video [Reinier] gives an overview of LoRa for those who might be unfamiliar. Followed by results of his experiments integrating LoRa functionality into Vinduino, and ending with a call to action for hackers to help grow the LoRa network. It sounds like he’s become quite the champion for the cause! He’s even giving a hands-on workshop at Supercon where you can build your own LoRa connected sensor. (Get tickets here.)

We’re always happy to see open-source hardware projects like Vinduino succeed, transitioning to a product that solve real world problems. We know there are even more promising ideas out there, which is why Hackaday’s sister company Tindie is funding a Project to Product program to help this year’s winners follow in Vinduino’s footsteps. We look forward to sharing more success stories yet to come.

After The Prize: What’s Next For The Light Electric Utility Vehicle

April 13, 2016 by Jenny List 16 Comments

Winner of the third place in last year’s Hackaday Prize was [Chris Low]’s Light Electric Utility Vehicle. In case you think that once a Hackaday Prize is in the bag then that’s it and the project creator packs up and goes home, [Chris] dispels that idea, he’s invested his winnings straight back into his project and posted his latest progress on an improved Mk3 model.

Light Electric Utility Vehicle, 2015-style

We first covered the Light Electric Utility Vehicle back in June 2015 when it was first entered for the 2015 Hackaday Prize. The aim was to produce a rugged and simple small electric vehicle that could be powered by solar energy and that was suitable for the conditions found in South Sudan, where [Chris] works. The vehicle as we saw it then was an articulated design, with chain drive to bicycle-style wheels. The Mk3 version by comparison has lost the articulation in favour of rack-and-pinion steering, has in-hub motors instead of chain drive, and now features coil-spring suspension. You might comment that it has lost some of its original simplicity and become something more like a conventional electric UTV, but along the way it has also become more of a practical proposition as an everyday vehicle.

You can follow the entire build log on the Light Electric Utility Vehicle’s project page on hackaday.io, and below the break have a look at [Chris]’s video showing it in action. Continue reading “After The Prize: What’s Next For The Light Electric Utility Vehicle” →

23 Superconference Talks You Shouldn’t Miss

December 24, 2015 by Brian Benchoff 7 Comments

November marked our inaugural Hackaday Superconference, something we’ve been wanting to do for a very long time. Hackaday already has a massive and vibrant online community, but until now, we haven’t asked people to come together for a hardware conference that spans a full weekend. The Supercon is Hackaday incarnate, and hundreds of very cool people showed up for a few dozen talks, amazing workshops, and a lot more.

Over the past month, we’ve been putting together a compilation of everything that happened at the first Hackaday Superconference. This includes videos of all the talks, relevant asides, and posts for everything that happened over a two-day conference. Even if you couldn’t make it out to our first con, this great material that should be shared by all.

Below is a YouTube playlist of all the talks. If you’re looking for eight hours to kill over the holiday weekend, well, there you have it. After the break is the complete conference indexed by day and speaker, with links to the talk and accompanying Hackaday post.

We’d like to thank everyone who came out to the first Hackaday Supercon, with a huge shout-out to the speakers, workshop organizers, and volunteers. It couldn’t have happened without the full support of the Hackaday community. That’s good, because we’re going to be doing this again next year.

Antti Lukats: The Past, Present, And Future Of Programmable Logic

December 19, 2015 by Brian Benchoff 14 Comments

[Antti] has gained a bit of a reputation over on Hackaday.io – he has a tremendous number of FPGA projects on hackaday.io, and they’re all open source. If you’re looking for street cred with FPGAs, [Antti] has it. His Hands-on experience with FPGAs and CPLDs stretches back to the very first chips in the 70s. We’re so happy that he’s working to share this depth of knowledge, and that includes this talk he gave a few weeks ago at the Hackaday SuperConference. Take a look and then join us after the break for an overview of the FPGA terrain, then and now.

Immersive Theatre Via IBeacons With Dustin Freeman

December 18, 2015 by Brandon Dunson 2 Comments

Combining backgrounds in math and theater, [Dustin Freeman] works on immersive, interactive theatrical experiences. During the day [Dustin] is a Spatial Interaction Engineer at Occipital, who makes the Structure Sensor. In his spare time [Dustin] works on digital theatre projects that bring the theatre goer far past the traditional row of seats.

The concept of immersive theatre is similar to ‘escape the room’ challenges and choose your own adventure experiences, in that the participants control the outcome of the experience by making decisions from the information supplied to them. [Dustin] explains in his talk that the feeling of trying to beat the clock that exists in escape the room challenges is not helpful in Floodlight’s The Painting. Floodlight is a theatre production company and The Painting is the immersive theatre experience put together by [Joshua Marx], professor of acting at San Jose State and [Dustin Freeman] who presented this 2015 Hackaday SuperConference talk.

Vinduino: Full Irrigation With 25% Less Water

December 11, 2015 by Brian Benchoff 6 Comments

Irrigation is a fairly crude practice. Sure, there are timers, and rain sensors, but all in all we’re basically dumping water on the ground and guessing at the right amount. [Reinier van der Lee] wanted a better way to ensure the plants in his vineyard are getting the right amount of water. And this is Goldilocks’ version of “right”, not too little but also not too much. Southern California is in an extreme/exceptional drought. Water costs a lot of money, but it is also scarce and conservation has a wider impact than merely the bottom line.

His solution is the Vinduino project. It’s a set of moisture sensors that work in conjunction with a handheld device to measure the effect of irrigation. Multiple moisture sensors are buried at different depths: near the surface, at root level, and below root level. This lets you know when the water is getting to the root system, and when it has penetrated further than needed. The project was recognized as the Best Product in the 2015 Hackaday Prize, and [Reinier] presented the project during his talk at the Hackaday SuperConference. Check out the video of that talk below, and join us after the break for a look at the development of this impressive product.

Creating Art In A Robot That Tastes With Its Feet

December 8, 2015 by Brian Benchoff 7 Comments

[Sarah Petkus] started off her career as a visual artist with traditional mediums. She has a webcomic called Gravity Road, but somewhere along the line she wanted her creations to come alive. These characters are robots – artistically designed robots – and turning this type of art into a real object isn’t something that happens very often.

Robots usually aren’t art. A Roomba is just a vacuum cleaner that’s meant to turn on a dime, thus the circular shape. The welding robots in a car factory aren’t art, they’re only tools to assemble cars. These are just devices built for a single purpose, and art is for any or every purpose. It’s not something you can really design, but you can engineer a few interesting solutions.
