IoT For Agriculture Hack Chat With Akiba

Join us Wednesday at 5:00 PM Pacific time for the IoT and Agriculture Hack Chat with Akiba!

Note the different time than our usual Hack Chat slot! Akiba willi be joining us from Japan.

No matter what your feelings are about the current state of the world, you can’t escape the fact that 7.7 billion humans need to be fed every day. That means a lot of crops to grow and harvest and a lot of animals to take care of and bring to market. And like anything else, technology can make that job easier and more productive.

join-hack-chatTo test concepts at the interface between technology and agriculture, Akiba has developed HackerFarm, a combination of homestead, hackerspace, and small farm in Japan. It’s a place where hackers with agriculture-related projects can come to test ideas and collaborate with other people trying to solve the problems of a hungry world by experimenting on an approachable scale with open-source technology.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, May 15 at 5:00 PM Pacific time. If time zones have got you down, we have a handy time zone converter.

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about.

A Farmer’s Guide To Technology

One of the hardest aspects of choosing a career isn’t getting started, it’s keeping up. Whether you’re an engineer, doctor, or even landscaper, there are always new developments to keep up with if you want to stay competitive. This is especially true of farming, where farmers have to keep up with an incredible amount of “best practices” in order to continue being profitable. Keeping up with soil nutrient requirements, changing weather and climate patterns, pests and other diseases, and even equipment maintenance can be a huge hassle.

A new project at Hackerfarm led by [Akiba] is hoping to take at least one of those items off of farmers’ busy schedules, though. Their goal is to help farmers better understand the changing technological landscape and make use of technology without having to wade through all the details of every single microcontroller option that’s available, for example. Hackerfarm is actually a small farm themselves, so they have first-hand knowledge when it comes to tending a plot of land, and [Bunnie Huang] recently did a residency at the farm as well.

The project strives to be a community for helping farmers make the most out of their land, so if you run a small farm or even have a passing interest in gardening, there may be some useful tools available for you. If you have a big enough farm, you might even want to try out an advanced project like an autonomous tractor.

Joe Kim: Where Technology And Art Collide

The rewards of being a writer for Hackaday are many, but aside from the obvious perks like the secret Hackaday handshake and admission to the private writer’s washroom, having the opportunity to write original content articles is probably the best part of the job. It gets even better, though, because after you submit an article, you’ll eventually get an email from Supplyframe Art Director Joe Kim with a Dropbox link to the original art he has created to accompany your piece. No matter where I am when that email comes in, I click on the link immediately, eager to see what Joe has come up with. And I’m never disappointed.

Silicon Valley Was Built On Tubes Of Glass

Lee de Forest

Bill Shockley brought the transistor to a pasture in Palo Alto, but he didn’t land there by chance. There was already a plot afoot which had nothing to do with silicon, and it had already been a happening place for some time by then.

Often overshadowed by Edison and Menlo Park or Western Electric and its Bell Labs, people forget that the practical beginning of modern radio and telecommunications began unsuspectingly in the Bay Area on the shoestring-budgeted work benches of Lee de Forest at Federal Telegraph.

As the first decade of the 20th century passed, Lee de Forest was already a controversial figure. He had founded a company in New York to develop his early vacuum tubes as detectors for radio, but he was not very good at business. Some of the officers of the company decided that progress was not being made fast enough and drained the company of assets while de Forest was away. This led to years of legal troubles and the arrest of many involved due to fraud and loss of investors’ money.

Why I Got The Job

Hackaday readers are a vast and varied bunch. Some of us would call ourselves engineers or are otherwise employed in some kind of technical role. Others may still be studying to gain the requisite qualifications and are perhaps wondering just how to complete that final leap into the realm of gainful employment. Well, this one’s for you.

What sort of job are you looking for?

You might be a straight, down the lines, petroleum engineering graduate who’s looking to land a job in the oil and gas industry. Conversely, you might be an arts student who’s picked up a few skills with electronics over the years and are keen to gain a position doing grand installation pieces for musuems or corporate clients.

There’s a broad spectrum of jobs out there that require high-level technical skills, and my first piece of advice is that you shouldn’t limit yourself. There are things you can do to keep your options open, even over a long career – these could pay dividends when you’re looking for a seachange.

[Daito Manabe] Interview: Shocking!

We’ve loved [Daito Manabe]’s work for a while now. Don’t know [Daito]? Read this recent interview with him and catch up. Is he a hacker’s artist, or an artist’s hacker?

My personal favorite hack of his is laser painting apparatus from 2011. The gimmick is that he uses the way the phosphors fade out to create a greyscale image. Saying that is one thing, but watching it all come together in time is just beautiful.

Maybe you’ve seen his facial-electrocution sequencer (words we never thought we’d write! YouTube link). He’s taken that concept and pushed it to the limit — setting up the same sequences on multiple people make them look eerily like the sacks of meat that they are, until everyone laughs at the end of the experiment and they’re all back to being human.

Anyway, if you didn’t know [Daito], check out the rest of his work. Have any other favorite tech artists that we’re missing? Drop us a line.

We Recommend That You Enter A Cyclocopter From The Front

It’s crazy to think that we’ve optimized the heck out of some types of powered flight when there are entire theories and methods that haven’t even seen many government research dollars, let alone the light of day. The cyclocopter is apparently one of those. It was dreamt up around the same time as a helicopter, but was too audacious for the material science of the time. We have helicopters, but [Professor Moble Benedict] and his graduate students, [Carl Runco] and [David Coleman], hope to bring cyclocopters to reality soon.

For obvious reasons they remind us of cyclocranes, as the wings rotate around their global axis, they also rotate back and forth in a cycloidal pattern around their local axis. By changing this pattern a little bit, the cyclocopter can generate a wide variety of thrust vectors, and, hopefully, zip around all over the place. Of course, just as a helicopter needs a prop perpendicular to its main rotor on its tail to keep if from spinning around its axis, the cyclocopter needs a prop facing upwards on its tail.

It does have a small problem though. The bending force on its wings are so strong that they tend to want to snap and fly off in all different directions. Fortunately in the past hundred years we’ve gotten ridiculously good at certain kinds of material science. Especially when it comes to composites we might actually be able to build blades for these things. If we can do that, then the sky’s the limit.

[Professor Benedict] and his team are starting small. Very small. Their first copter weighs in under 30 grams. It took them two years of research to build. It will hopefully lead to bigger and bigger cyclocopters until, perhaps, we can even build one a person can get into, and get out of again.
