Using data to help a school garden

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/using-data-to-help-a-school-garden/

Chris Aviles, aka the teacher we all wish we’d had when we were at school, discusses how his school is in New Jersey is directly linking data with life itself…

Over to you, Chris.

Every year, our students take federal or state-mandated testing, but what significant changes have we made to their education with the results of these tests? We have never collected more data about our students and society in general. The problem is most people and institutions do a poor job interpreting data and using it to make meaningful change. This problem was something I wanted to tackle in FH Grows.

FH Grows is the name of my seventh-grade class, and is a student-run agriculture business at Knollwood Middle School in Fair Haven, New Jersey. In FH Grows, we sell our produce both online and through our student-run farmers markets. Any produce we don’t sell is donated to our local soup kitchen. To get the most out of our school gardens, students have built sensors and monitors using Raspberry Pis. These sensors collect data which then allows me to help students learn to better interpret data themselves and turn it into action.

Turning data into action

In the greenhouse, our gardens, and alternative growing stations (hydroponics, aquaponics, aeroponics) we have sensors that log the temperature, humidity, and other important data points that we want to know about our garden. This data is then streamed in real time, online at FHGrows.com. When students come into the classroom, one of the first things we look at is the current, live data on the site and find out what is going on in our gardens. Over the course of the semester, students are taught about the ideal growing conditions of our garden. When looking at the data, if we see that the conditions in our gardens aren’t ideal, we get to work.

If we see that the greenhouse is too hot, over 85 degrees, students will go and open the greenhouse door. We check the temperature a little bit later, and if it’s still too hot, students will go turn on the fan. But how many fans do you turn on? After experimenting, we know that each fan lowers the greenhouse temperature between 7-10 degrees Fahrenheit. Opening the door and turning on both fans can bring a greenhouse than can push close to 100 degrees in late May or early June down to a manageable 80 degrees.

Turning data into action can allow for some creativity as well. Over-watering plants can be a real problem. We found that our plants were turning yellow because we were watering them every day when we didn’t need to. How could we solve this problem and become more efficient at watering? Students built a Raspberry Pi that used a moisture sensor to find out when a plant needed to be watered. We used a plant with the moisture sensor in the soil as our control plant. We figured that if we watered the control plant at the same time we watered all our other plants, when the control plant was dry (gave a negative moisture signal) the rest of the plants in the greenhouse would need to be watered as well.

Chris Aviles Innovation Lab Raspberry Pi Certified Educator

This method of determining when to water our plants worked well. We rarely ever saw our plants turn yellow from overwatering. Here is where the creativity came in. Since we received a signal from the Raspberry Pi when the soil was not wet enough, we played around with what we could do with that signal. We displayed it on the dashboard along with our other data, but we also decided to make the signal send as an email from the plant. When I showed students how this worked, they decided to write the message from the plant in the first person. Every week or so, we received an email from Carl the Control Plant asking us to come out and water him!

 

If students don’t honour Carl’s request for water, use data to know when to cool our greenhouse, or had not done the fan experiments to see how much cooler they make the greenhouse, all our plants, like the basil we sell to the pizza places in town, would die. This is the beauty of combining data literacy with a school garden: failure to interpret data then act based on their interpretation has real consequences: our produce could die. When it takes 60-120 days to grow the average vegetable, the loss of plants is a significant event. We lose all the time and energy that went into growing those plants as well as lose all the revenue they would have brought in for us. Further, I love the urgency that combining data and the school garden creates because many students have learned the valuable life lesson that not making a decision is making a decision. If students freeze or do nothing when confronted with the data about the garden, that too has consequences.

Using data to spot trends and make predictions

The other major way we use data in FH Grows is to spot trends and make predictions. Different to using data to create the ideal growing conditions in our garden every day, the sensors that we use also provide a way for us to use information about the past to predict the future. FH Grows has about two years’ worth of weather data from our Raspberry Pi weather station (there are guides online if you wish to build a weather station of your own). Using weather data year over year, we can start to determine important events like when it is best to plant our veggies in our garden.

For example, one of the most useful data points on the Raspberry Pi weather station is the ground temperature sensor. Last semester, we wanted to squeeze in a cool weather grow in our garden. This post-winter grow can be done between March and June if you time it right. Getting an extra growing cycle from our garden is incredibly valuable, not only to FH Grows as business (since we would be growing more produce to turn around and sell) but as a way to get an additional learning cycle out of the garden.

So, using two seasons’ worth of ground temperature data, we set out to predict when the ground in our garden would be cool enough to do this cool veggie grow. Students looked at the data we had from our weather station and compared it to different websites that predicted the last frost of the season in our area. We found that the ground right outside our door warmed up two weeks earlier than the more general prediction given by websites. With this information we were able to get a full cool crop grow at a time where our garden used to lay dormant.

We also used our Raspberry Pi to help us predict whether or not it was going to rain over the weekend. Using a Raspberry Pi connected to Weather Underground and previous years’ data, if we believed it would not rain over the weekend we would water our gardens on Friday. If it looked like rain over the weekend, we let Mother Nature water our garden for us. Our prediction using the Pi and previous data was more accurate for our immediate area than compared to the more general weather reports you would get on the radio or an app, since those considered a much larger area when making their prediction.

It seems like we are going to be collecting even more data in the future, not less. It is important that we get our students comfortable working with data. The school garden supported by Raspberry Pi’s amazing ability to collect data is a boon for any teacher who wants to help students learn how to interpret data and turn it into action.

Raspberry Pi interactive wind chimes

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/interactive-wind-chimes/

Grab yourself a Raspberry Pi, a Makey Makey, and some copper pipes: it’s interactive wind chime time!

Perpetual Chimes

Perpetual Chimes is a set of augmented wind chimes that offer an escapist experience where your collaboration composes the soundscape. Since there is no wind indoors, the chimes require audience interaction to gently tap or waft them and encourage/nurture the hidden sounds within – triggering sounds as the chimes strike one another.

Normal wind chimes pale in comparison

I don’t like wind chimes. There, I said it. I also don’t like the ticking of the second hand of analogue clocks, and I think these two dislikes might be related. There’s probably a name for this type of dislike, but I’ll leave the Googling to you.

Sound designer Frazer Merrick’s interactive wind chimes may actually be the only wind chimes I can stand. And this is due, I believe, to the wonderful sounds they create when they touch, much more wonderful than regular wind chime sounds. And, obviously, because these wind chimes incorporate a Raspberry Pi 3.

Since there is no wind indoors, the chimes require audience interaction to gently tap or waft them and encourage/nurture the hidden sounds within — triggering sounds as the chimes strike one another. Since the chimes make little acoustic noise, essentially they’re broken until you collaborate with them.

Aardman has created so many characters that the members of Raspberry Pi hold dear in our hearts. From the early days of Morph’s interactions with Tony Hart, or Christmas evenings sat watching the adventures of Wallace and Gromit, through to their grand cinema-screen epics, we all have a soft spot for the wonderful creatures this talented bunch have invented.

So when Aardman approached us to ask if we’d like to be the Educational Partner for their new film A Shaun the Sheep Movie: Farmageddon, we obviously jumped at the chance. Aardman are passionate about education, and we are too, so this really was a no-brainer.

Shaun the Sheep: Mission to Space

Today we are launching the brand-new, global Code Club competition ‘Shaun the Sheep: Mission to Space’.

We’re asking young people in registered Code Clubs across the world to create awe-inspiring animations featuring Shaun the Sheep and his new friend Lu-La’s adventures, by following our specially themed ‘Shaun the Sheep: Mission to Space’ Scratch project guide!

The ‘Shaun the Sheep: Mission to Space’ competition closes October 25 2019, and you can find more information on the Code Club website.

Shaun the Sheep character hunt

For those of you who aren’t in a Code Club, we’re also running a second giveaway here on the Raspberry Pi blog. For your chance to enter, you need to find three characters from the film that we’ve hidden throughout the Raspberry Pi and Code Club websites. Once you’ve found three, fill in this form, and we’ll pick ten winners to receive some A Shaun the Sheep Movie: Farmageddon goodies, including stickers and a pair of Shaun the Sheep ears.

Please note: at least one of the characters you submit must be from the Code Club website, so get hunting!

The closing date for the character hunt is 4 October 2019.

Both competitions are open to everyone, no matter where in the world you are.

We’ll also be uploading the ‘Shaun the Sheep: Mission to Space’ Scratch project to the Raspberry Pi desktops at the Raspberry Pi Store, Cambridge, so make sure you stop by this coming half-term to try your hand at coding your own Shaun the Sheep adventure.

How you, an adult, can take part in the European Astro Pi Challenge

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/how-you-an-adult-take-part-in-european-astro-pi-challenge/

So, yesterday we announced the launch of the 2019/2020 European Astro Pi Challenge, and adults across the globe groaned with jealousy as a result. It’s OK, we did too.

The Astro Pi Challenge is the coolest thing ever

The European Astro Pi Challenge is ridiculously cool. It’s definitely one of the most interesting, awesome, spectacular uses of a Raspberry Pi in the known universe. Two Raspberry Pis in stellar, space-grade aluminium cases are currently sat aboard the International Space Station, waiting for students in ESA Member States to write code to run on them to take part in the Astro Pi Challenge.

But what if, like us, you’re too old to take part in the challenge? How can you get that great sense of space wonderment when you’re no longer at school?

You’re never too old…even when you’re too old

If you’re too old to take part in the challenge, it means you’re old enough to be a team mentor. Team mentors are responsible for helping students navigate the Astro Pi Challenge, ensuring that everyone is where they’re meant to be, doing what they’re meant to be doing. You’ll also also the contact between the team and us, Raspberry Pi and ESA. You’re basically a team member.

You’re basically taking part.

Mission Zero requires no coding knowledge

Mission Zero requires very little of its participants:

  • They don’t need to have any prior knowledge of coding
  • They don’t need a Raspberry Pi

And while they need an adult to supervise them, said adult doesn’t need any coding experience either.

(Spoiler alert: you’re said adult.)

Instead, you just need an hour to sit down with your team at a computer and work through some directions. And the result? Your team’s completed code will run aboard the International Space Station, and they’ll get a certificate to prove it.

You really have no excuse

If you live in an ESA Member State and know anyone aged 14 years or younger, there is absolutely no reason for them not to take part in Astro Pi Mission Zero. And, since they’re probably not reading this blog post right now, it’s your responsibility to tell them about Astro Pi. This is how you take part in the European Astro Pi Challenge: you become the bearer of amazing news when you sit your favourite kids down and tell them they’re going to be writing code that will run on the International Space Station…IN SPACE!

To find out more about Mission Zero, click here. We want to see you pledging your support to your favourite non-adults, so make sure to tell us you’re going to be taking part by leaving a comment below.

There really is no excuse.

Run your code aboard the International Space Station with Astro Pi

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/run-your-code-aboard-the-international-space-station-with-astro-pi/

Each year, the European Astro Pi Challenge allows students and young people in ESA Member States (or Slovenia, Canada, or Malta) to write code for their own experiments, which could run on two Raspberry Pi units aboard the International Space Station.

The Astro Pi Challenge is a lot of fun, it’s about space, and so that we in the Raspberry Pi team don’t have to miss out despite being adults, many of us mentor their own Astro Pi teams — and you should too!

So, gather your team, stock up on freeze-dried ice cream, and let’s do it again: the European Astro Pi Challenge 2019/2020 launches today!

Luca Parmitano launches the 2019-20 European Astro Pi Challenge

ESA astronaut Luca Parmitano is this year’s ambassador of the European Astro Pi Challenge. In this video, he welcomes students to the challenge and gives an overview of the project.

The European Astro Pi Challenge 2019/2020 is made up of two missions: Mission Zero and Mission Space Lab.

Astro Pi Mission Zero

Mission Zero has been designed for beginners/younger participants up to 14 years old and can be completed in a single session. It’s great for coding clubs or any groups of students don’t have coding experience but still want to do something cool — because having confirmation that code you wrote has run aboard the International Space Station is really, really cool! Teams write a simple Python program to display a message and temperature reading on an Astro Pi computer, for the astronauts to see as they go about their daily tasks on the ISS. No special hardware or prior coding skills are needed, and all teams that follow the challenge rules are guaranteed to have their programs run in space!

Mission Zero eligibility

  • Participants must be no older than 14 years
  • 2 to 4 people per team
  • Participants must be supervised by a teacher, mentor, or educator, who will be the point of contact with the Astro Pi team
  • Teams must be made up of at least 50% team members who are citizens of an ESA Member* State, or Slovenia, Canada, or Malta

Astro Pi Mission Space Lab

Mission Space Lab is aimed at more experienced/older participants up to 19 years old, and it takes place in 4 phases over the course of 8 months. The challenge is to design and write a program for a scientific experiment to be run on an Astro Pi computer. The best experiments will be deployed to the ISS, and teams will have the opportunity to analyse and report on their results.

Raspberry Pi in space!

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/raspberry-pi-in-space/

We love ‘Raspberry Pi + space’ stuff. There, I’ve said it. No taksies backsies.

From high-altitude balloon projects transporting Raspberry Pis to near space, to our two Astro Pi units living aboard the International Space Station, we simply can’t get enough.

Seriously, if you’ve created anything space-related using a Raspberry Pi, please tell us!

Capturing Earth from low orbit

Surrey Satellite Technology Ltd (SSTL) sent a Raspberry Pi Zero to space as part of their Demonstration of Technology (DoT-1) satellite, launched aboard a Soyuz rocket in July.

So, not that we’re complaining, but why did they send the Raspberry Pi Zero to space to begin with? Well, why not? As SSTL state:

Whilst the primary objective of the 17.5kg self-funded DoT-1 satellite is to demonstrate SSTL’s new Core Data Handling System (Core-DHS), accommodation was made available for some additional experimental payloads including the Raspberry Pi camera experiment which was designed and implemented in conjunction with the Surrey Space Centre.

Essentially, if you can fit a Raspberry Pi into your satellite, you should.


Managing Director of SSTL Sarah Parker went on to say that “the success of the Raspberry Pi camera experiment is an added bonus which we can now evaluate for future missions where it could be utilised for spacecraft ‘selfies’ to check the operation of key equipments, and also for outreach activities.”

SSTL’s very snazzy-looking Demonstration of Technology (DoT-1) satellite

The onboard Raspberry Pi Zero was equipped with a Raspberry Pi Camera Module and a DesignSpark M12 Mount Lens. Image data captured on the space-bound Raspberry Pi was sent back to the SSTL ground station via the Core-DHS.

So, have you sent a Raspberry Pi to space? Or anywhere else we wouldn’t expect a Raspberry Pi to go? Let us know in the comments!

Picademy Bytes: free physical computing training for teachers

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/picademy-bytes-free-physical-computing-training-for-teachers/

Five years ago, the Raspberry Pi Foundation recognised a need for free, high-quality CPD for educators. In response, we started running Picademy, a two-day training event that provides educators all over the UK and North America with the knowledge and skills they need to teach computing with confidence, creativity, and excitement.

We are delighted to now bring you a new free training programme called Picademy Bytes for teachers in the UK who are unable to attend the two-day Picademy events. Picademy Bytes training sessions are 60- to 90-minute community-led events taking place at various UK locations, led by Community Trainers who we ourselves have inducted.

The aim of Picademy Bytes is to highlight the value of delivering curriculum objectives through physical computing activities: the programme provides teachers with the opportunity to experiment with physical computing in a short, face-to-face training session. Teachers can then take what they’ve learned back to their schools, to use or adapt for their own Computing lessons.

Introducing our Community Trainers

In June this year, we invited our first four Community Trainers to attend an induction session, where we introduced them to the resources for their Picademy Bytes sessions, and they gave us feedback on our plans and the session content.


All four Community Trainers are teachers and Raspberry Pi Certified Educators, having attended Picademy in the past. They volunteered to become Community Trainers because they are enthusiastic to help other teachers in their local areas to deliver exciting learning experiences for their students.

The first Picademy Bytes session took place in July at the Computer Science in Schools Conference 2019 at Staffordshire University in Stoke-on-Trent, and most attendees were secondary school teachers. Attendees described the session as “well-balanced [between] theory and practical” and said that it was “very informative and provided ideas for the classroom”.

Look out for Picademy Bytes sessions in a city near you!

Upcoming Picademy Bytes sessions will soon be listed on the Computing at School website and on the Raspberry Pi Foundation website. If you are based in or near Belfast, Bradford, South Wales, Hull, London, North Devon, or Plymouth, look out for events near you from this month! And there will be plenty more events in locations across the UK after that. We look forward to seeing you there!

Controlling a boom lift with a Raspberry Pi

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/controlling-a-boom-lift-with-a-raspberry-pi/

Do you have a spare Raspberry Pi lying around? And a Bluetooth games controller? Do you have access to boom lifts or other heavy machinery?

Well, then we most certainly (do not) have the project for you.

Allow us to introduce what is (possibly, probably, hopefully) the world’s first Raspberry Pi–controlled boom lift. Weighing in at 13,000lb, this is the epitome of DON’T try this at home.

Please don’t!

Raspberry Pi-controlled boom lift

Shared on Reddit over the weekend, u/Ccundiff12’s project received many an upvote and concerned comment, but, as the poster explains, hacking the boom is a personal project for personal use to fix a specific problem — thankfully not something built for the sake of having some fun.

Meet STRETCH. Circa 1989 Genie Boom that I bought (cheap) from a neighbor. I use it to trim trees around my property. Its biggest problem was that it always got stuck. It’s not really an off-road vehicle. It used to take two people to move it around… one to drive the lift, and the other to push it with the tractor when it lost traction. The last time it got stuck, I asked my wife to assist by driving one of the two…….. the next day I started splicing into the control system. Now I can push with the tractor & run the boom via remote!

Visit the original Reddit post for more information on the build. And remember: please do not try this at home.

Build a xylophone-playing robot | HackSpace magazine #22

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/build-a-xylophone-playing-robot-hackspace-magazine-22/

HackSpace magazine issue 22 is out now, and our favourite tutorial this month will show you how to make this, a xylophone-playing robot!

Build a glockenspiel-playing robot with HackSpace magazine

Why spend years learning to play a musical instrument when you could program a robot to do it for you? This month HackSpace magazine, we show you how to build a glockenspiel-playing robot. Download the latest issue of HackSpace for free: http://rpf.io/hs22yt Follow HackSpace on Instagram: http://rpf.io/hsinstayt

If programming your own instrument-playing robot isn’t for you, never fear, for HackSpace magazine is packed full of other wonderful makes and ideas, such as:

  • A speaker built into an old wine barrel
  • Free-form LEDs
  • Binary knitwear
  • A Raspberry Pi–powered time machine
  • Mushroom lights
  • A…wait, hold on, did I just say a Raspberry Pi–powered time machine? Hold on…let me just download the FREE PDF and have a closer look. Page 14, a WW2 radio broadcast time machine built by Adam Clark. “I bought a very old, non-working valve radio, and replaced the internals with a Raspberry Pi Zero on a custom 3D-printed chassis.” NICE!


Honestly, this month’s HackSpace is so full of content that it would take me all day to go through everything. But, don’t take my word for it — try it yourself.

HackSpace magazine is out now, available in print from your local newsagent or from the Raspberry Pi Store in Cambridge, online from Raspberry Pi Press, or as a free PDF download.

Retrofit a vintage camera flash with a Raspberry Pi Camera Module

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/retrofit-vintage-camera-flash-with-camera-module/

Wanting to break from the standard practice of updating old analogue cameras with digital technology, Alan Wang decided to retrofit a broken vintage camera flash with a Raspberry Pi Zero W to produce a video-capturing action cam.

Raspberry Pi Zero Flash Cam Video Test

Full story of this project: https://www.hackster.io/alankrantas/raspberry-pi-zero-flash-cam-359875

By hacking a somewhat gnarly hole into the body of the broken flash unit, Alan fit in the Raspberry Pi Zero W and Camera Module, along with a few other components. He powers the whole unit via a USB power bank.

At every touch of the onboard touchpad, the retrofit camera films 12 seconds of footage and saves it as an MP4 file on the onboard SD card or an optional USB flash drive.

While the project didn’t technically bring the flash unit back to life — as the flash function is still broken — it’s a nice example of upcycling old tech, and it looks pretty sweet. Plus, you can attach it to your existing film camera to produce some cool side-by-side comparison imagery, as seen in the setup above.

For a full breakdown of the build, including the code needed to run the camera, check out the project’s Hackster.io page.

Digital making outdoors

Sure, there may be a few obstacles in your way whenever you try to complete a digital making project outside. Poor WiFi connections are always a problem, the sun will most certainly glare off your screen, and don’t even get me started on the lack of power supplies. But that’s where The MagPi magazine comes in, providing you with every tip and trick you need to move your making into the fresh air of the great outdoors.

Visit The MagPi magazine’s website, where you’ll be able to download the PDF for free, saving money, time, and trees! Woohoo!

Build your own Raspberry Pi night vision camera

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/build-your-own-raspberry-pi-night-vision-camera/

A Raspberry Pi Zero W, Pimoroni HyperPixel screen, and Raspberry Pi IR Camera Module are all you need to build this homemade night vision camera.

Raspberry Pi night vison camera

Built into the body of an old camera flash, Dan’s Raspberry Pi night vision camera is a homage to a childhood spent sneaking around the levels of Splinter Cell. Says Dan:

The iconic image from the game is the night vision goggles that Sam Fisher wears. I have always been fascinated by the idea that you can see in the dark and this formed the foundation of my idea to build a portable hand-held night vision piece of equipment.

The camera, running on Raspbian, boasts several handy functions, including touchscreen controls courtesy of the Pimoroni HyperPixel, realtime video and image capture, and a viewing distance of two to five metres.

It’s okay to FAIL

Embracing the FAIL (First Attempt In Learning) principle, Dan goes into detail about the issues he had to overcome while building the camera, which is another reason why we really enjoyed this project. It’s okay to fail when trying your hand at digital making, because you learn from your mistakes! Dan’s explanations of the struggles he faced and how he overcame them are 👌.

Use PlayStation Buzz! controllers with a Raspberry Pi

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/use-playstation-buzz-controllers-with-a-raspberry-pi/

Buzz! was a favourite amongst my university housemates and me. With popular culture questions asked by an animated Jason Donovan, answered using real-life quiz controllers with a big red button, what’s not to like?

But, as with most of the tech available in the early 2000s, my Buzz! controllers now sit in a box somewhere, dusty and forgotten.

That’s why it is so goshdarn delightful to see PiMyLifeUp breathe new life into these awesome-looking games controllers.

Bringing Buzz! back

The tutorial uses the hidapi library to communicate with the controllers, allowing them to control functions through the Raspberry Pi, and the Raspberry Pi to control the LED within the big red button.

By the end of this tutorial, you will have learned how to read information about all your USB devices, learned how to read data that the devices are sending back and also how to write a library that will act as a simple wrapper to dealing with the device.

Aside from the Buzz! controllers, available on eBay or similar for a few pounds, you only need a Raspberry Pi and its essential peripherals to get started, as the controllers connect directly via USB — thanks, Buzz!

PiMyLifeUp’s tutorial is wonderfully detailed, explaining the hows and whys of the lines of code needed to turn your old Buzz! controllers into a quiz game written in Python that uses the coloured buttons to answer multiple-choice questions.

Guitar Hero, dance mats, Donkey Kong Bongos — what other gaming peripherals would you like to bring back to life?
