Plan Bee

Bees are important. I find myself saying this a lot and, slowly but surely, the media seems to be coming to this realisation too. The plight of the bee is finally being brought to our attention with increasing urgency.

A colony of bees make honey

Welcome to the house of buzz.

In the UK, bee colonies are suffering mass losses. Due to the use of bee-killing fertilisers and pesticides within the farming industry, the decline of pollen-rich plants, the destruction of hives by mites, and Colony Collapse Disorder (CCD), bees are in decline at a worrying pace.

Bee Collision

When you find the perfect GIF…

One hint of a silver lining is that increasing awareness of the crisis has led to a rise in the number of beekeeping hobbyists. As getting your hands on some bees is now as simple as ordering a box from the internet, keeping bees in your garden is a much less daunting venture than it once was. 

Taking this one step further, beekeepers are now using tech to monitor the conditions of their bees, improving conditions for their buzzy workforce while also recording data which can then feed into studies attempting to lessen the decline of the bee.

WDLabs recently donated a PiDrive to the Honey Bee Gardens Project in order to help beekeeper David Ammons and computer programmer Graham Toal create The Hive Project, an electric beehive colony that monitors real-time bee data.

Electric Bee Hive

The setup records colony size, honey production, and bee health to help combat CCD.

Colony Collapse Disorder (CCD) is decidedly mysterious. Colonies hit by the disease seem to simply disappear. The hive itself often remains completely intact, full of honey at the perfect temperature, but… no bees. Dead or alive, the bees are nowhere to be found.

To try to combat this phenomenon, the electric hive offers 24/7 video coverage of the inner hive, while tracking the conditions of the hive population.

Bee bringing pollen into the hive

This is from the first live day of our instrumented beehive. This was the only bee we spotted all day that brought any pollen into the hive.

Ultimately, the team aim for the data to be crowdsourced, enabling researchers and keepers to gain the valuable information needed to fight CCD via a network of electric hives. While many people blame the aforementioned pollen decline and chemical influence for the rise of CCD, without the empirical information gathered from builds such as The Hive Project, the source of the problem, and therefore the solution, can’t be found.

Bee making honey

It has been brought to our attention that the picture here previously was of a wasp doing bee things. We have swapped it out for a bee.

 

 

Ammons and Toal researched existing projects around the use of digital tech within beekeeping, and they soon understood that a broad analysis of bee conditions didn’t exist. While many were tracking hive weight, temperature, or honey population, there was no system in place for integrating such data collection into one place. This realisation spurred them on further.

“We couldn’t find any one project that took a broad overview of the whole area. Even if we don’t end up being the people who implement it, we intend to create a plan for a networked system of low-cost monitors that will assist both research and commercial beekeeping.”

With their mission statement firmly in place, the duo looked toward the Raspberry Pi as the brain of their colony. Finding the device small enough to fit within the hive without disruption, the power of the Pi allowed them to monitor multiple factors while also using the Pi Camera Module to record all video to the 314GB storage of the Western Digital PiDrive.

Data recorded by The Hive Project is vital to the survival of the bee, the growth of colony population, and an understanding of the conditions of the hive in changing climates. These are issues which affect us all. The honey bee is responsible for approximately 80% of pollination in the UK, and is essential to biodiversity. Here, I should hand over to a ‘real’ bee to explain more about the importance of bee-ing…

Rocket Man

James Dougherty, co-founder and owner of Real Flight Systems, was looking at how to increase the performance of his high-altitude rockets…

Rocket Pi High Altitude Rocket

These types of rockets… yeah…

James’s goal was to build a ‘plug and run’ video system within a rocket, allowing high-definition video to be captured throughout the entirety of the flight. He also required a fully functioning Linux system that would allow for the recording of in-flight telemetry.

You can totally see the direction he’s headed in, right?

This requirement called for long battery life, high storage to accommodate up to 1080p video, and a lightweight processor, allowing the rocket to be robust and reliable while in flight.

Unsurprisingly, James decided to use the Raspberry Pi for his build, settling for the model B.

Before starting the build, James removed the HDMI port, composite video output, USB post, audio jack, and Microchip LAN9512. Not only did this lessen the weight of the Pi, but these modifications also lowered the power needed to run the setup, thus decreasing the size of battery needed. This shrunken unit, completed with the addition of a Pi camera, meant the Pi could run for 8-10 hours with the recording quality lowered to 720p60 and no audio captured.

Rocket PI High Altitude Rocket

Slimline Pi, now with 40% less Pi.

Sadly, the first launch had its issues: the rocket suffered a system failure that resulted in the destruction of the micro SD during the Pegasus flight at BALLS 23, an experimental rocket launch event in the Blackrock desert, USA.

Rocket Pi High Altitude Rocket

Ruh-roh, Raggy…

Rockets Magazine managed to record the launch which shows the highlights mid-flight.

However, the next launch was far more successful, with close friend Jimmy Franco launching Rocket-Pi within a Dominator 4 to record the following footage.

(This clip comes with a motion sickness warning!)

Dominator 4 L1355 – TCC 02/21/15

Jimmy Franco flies Dominator-4 at TCC’s February Launch (02/21/15 on an L1355.

So what was next?

Aside from a few issues with Windows when trying to upload the footage post-flight, the main gripe was the lack of audio.

Investing in a new Raspberry Pi, making sure to keep more of the original components intact, James also updated the board with a USB microphone, added a USB flash drive to eliminate the Windows issues, and replaced the SD card with a lower storage option, as the footage was now stored in the flash drive.

1/3 Scale Nike L3150 – TCC Nike Smoke Drag Race 06/20/15

Launch and recovery of 1/3 Scale Nike Smoke at Tripoli Central Californias June 20th Launch. The vehicle flight-ready weighed 30 lbs, L3150 produces 800lbs initial thrust so we had about 26.6 G’s (burnt time 1.1440 seconds). Max speed: Mach 1.2; Max Altitude, 8,837′ AGL (GPS).

In the meantime, as James has continued to work on the Rocket-Pi, updating the hardware and code, he’s managed to put the Pi through some vigorous testing. During the most recent flight in Blackrock, the Pi reached 48K MSL (48000 feet above sea level… wow), at a speed of up to Mach 1.8 (1381 miles per hour… double wow).

Rocket Pi High Altitude Rocket

But I AM flying! And from way up here you all look like little ants.

Moving on from the build, James aims to upgrade various features. One of the most exciting upgrades looks to be the migration of Rocket-Pi to the Pi Zero, the smaller size allowing for multiple units in one rocket… creating 360-degree coverage of the flight (yes please!).

More of the build information, coding, and flight documentation can be found at the RFS website.

Hi Fi Raspberry Pi – digitising and streaming vinyl

Over at Mozilla HQ (where Firefox, a browser that many of you are using to read this, is made), some retro hardware hacking has been going on.

vinyl record

The Mozillans have worked their way through several office music services, but nothing, so far, has stuck. Then this home-made project, which started as a bit of a joke, landed on a countertop – and it’s stayed.

Matt Claypotch found a vinyl record player online, and had it delivered to the office, intending to tinker with it at home. It never made it that far. He and his colleagues spent their lunch hour at a local thrift store buying up random vintage vinyl…and the record player stayed in the office so everybody could use it.

Potch’s officemates embarked on a vinyl spending spree.

What could be better? The warm crackle of vintage vinyl, “random, crappy albums” you definitely can’t find on Spotify (and stuff like the Van Halen album above that you can find on Spotify but possibly would prefer not to)…the problem was, once the machine had been set up in a break room, only the people in that room could listen to the cheese.

Enter the Raspberry Pi, with a custom-made streaming setup. One Mozillan didn’t want to have to sit in the common area to get his daily dose of bangin’ choons, so he set up a Pi to stream music from the analogue vinyl over USB (it’s 2016, record players apparently have USB ports now) via an Icecast stream to headphones anywhere in the office. Analogue > digital > analogue, if you like.

The setup is surprisingly successful; they’ve organised other audio systems which weren’t very popular, but this one, which happened organically, is being used by the whole office.

You can listen to a podcast from Envoy Office Hacks about the setup, and the office’s reaction to it.

Mozilla, keep on bopping to disco Star Wars. (I’m off to see if I can find a copy of that record. It’s probably a lot better in my imagination than it is in real life, but BOY, is it good in my imagination*.)

*I found it on YouTube. It’s a lot better in my imagination.

One small step for Steph, one giant flap for makerkind

I’m Steph, I’m quite new to the Raspberry Pi Foundation, and I’m very new to Raspberry Pis. Until quite recently, any mention of pie to me meant that good food was on the horizon – now my horizons are much broader. I’ve been part of the Programmes Team at Pi Towers for about 3 months, and I’ve only just picked my jaw up from the floor in awe of the creative geniuses around me. The things that I’ve seen are mindboggling and I began to wonder how they were created. Well, there was only one way to find out – make something myself.

Steph and her creation

The smile of a happy maker

The time had come for me to get started in the world of digital making. I’ve always been into arts and crafts, and I love to put my own touch and personality on my possessions; sewing buttons and colourful things on to clothes, revamping drawer knobs, applying découpage to any plain bits of furniture, and taking over the world with my glue gun. However, making something digital from scratch was a daunting prospect! I wasn’t going to let it scare me, though; I’ve dived out of a plane before and landed with a smile on my face.

So, supported by my team and with that ‘Friday feeling’, I took the plunge and transformed into a digital maker for the afternoon. I was presented with a DIY Gamer Kit, from Technology Will Save Us, as my first project. I opened the box of components and loaded up the online instructions, then I had to take a deep breath and compose myself as I read the word ‘solder’. I was very excited that I was going to need to solder, then realised I didn’t know how to do it. Rachel Rayns, my lovely desk buddy, gave me a soldering tutorial; now, I feel like I can solder most metal things in the world. I loved it.

Steph learns to solder

The soldering skills that earned an Instagram marriage proposal.

I continued the rest of my mission on my own, with the incentive of being able to play Snake at the end of it. I worked my way through the kit, identifying all of the digital ingredients and joining them together in the right places. I soldered push buttons, LEDs, a buzzer, resistors, and many other components to a PCB (printed circuit board). I was amazed at how quickly the parts grew into a device that looked very much like a Game Boy, and I was impressed to see how it matched the photo instructions – very useful!

Following the instructions, I added a brain to my device in the form of an Arduino, and an acrylic accessory to the front and back. This was a great way to protect my game; if I’m honest, I may have dropped it a few times whilst fumbling through the engineers’ tool stash. Luckily, nothing fell apart, which was a testament to my new-found soldering skills. After fixing the spacers, nuts and bolts in place, the only thing left to do was to connect a 9v battery to the game, and then run through the office waving it around when it powered up.

I had made the DIY Gamer Kit, and in that moment I wasn’t sure which thing made me smile the most:

  • How quickly I was able to put it together – even though I stopped to admire my work every 5 minutes
  • The fact that I could now play Snake
  • Knowing that, against all odds, I hadn’t burnt myself
  • The idea of going to make something else straight away

Once my smile had shrunk back down to normal size, I was calm enough to think about doing some coding. I’ve been told that code can be used to solve real life problems, and I certainly needed it when I uploaded the game ‘Flappy Bird’ on to my new game machine and couldn’t survive for longer than 2 seconds. My problem was that my bird was flying far too fast to control – it had to be hacked! Again, with the help of Rachel we hacked the game and adapted the code. I was then able to play Flappy Bird at a much more reasonable flying speed. My problems didn’t quite stop here, though, as I continued to fly my bird into wall after wall, ending the game prematurely. We hacked it some more, and now I’ll never see the words ‘Game Over’ again.

Rachel and Steph go through Coding 101

Coding 101

I’ve been inspired to be more of a digital maker, because I enjoyed every minute of my very first project. I hope that others may find the same inspiration from the amount of joy on my face in the picture below. Go forth and make something, and you too could be this happy.

The Scratch Olympics

Since the Raspberry Pi Foundation merged with Code Club, the newly enlarged Education Team has been working hard to put the power of digital making into the hands of people all over the world.

Among the other work we’ve been doing, we’ve created a set of Scratch projects to celebrate the 2016 Olympic Games in Rio.

The initial inspiration for these projects were the games that we used to love as children, commonly referred to as ‘button mashers’. There was little skill required in these games: all you needed was the ability to smash two keys as fast as humanly possible. Examples of this genre include such classics as Geoff Capes Strongman and Daley Thompson’s Decathlon.

With the 2016 Olympics fast approaching, we began to reminisce about these old sports-themed games, and realised what fun today’s kids are missing out on. With that, the Scratch Olympics were born!

There are two resources available on the resources section of this site, the first of which is the Olympic Weightlifter project. With graphics conceived by Sam Alder and produced by Alex Carter, the project helps you create a button-masher masterpiece, producing your very own 1980s-style keyboard-killer that’s guaranteed to strike fear into the hearts of parents all over the world. Physical buttons are an optional extra for the faint of heart.

A pixellated weightlifter blows steam from his ears as he lifts a barbell above his head in an animated gif

The second game in the series is Olympics Hurdles, where you will make a hurdling game which requires the player to hit the keyboard rapidly to make the hurdler run, and use expert timing to make them jump over the hurdles at the right time.

Pixellated athletes approach, leap and clear a hurdle on an athletics track

You’ll also find three new projects over on the Code Club projects website. The first of these is Synchronised Swimming, where you’ll learn how to code a synchronised swimming routine for Scratch the cat, by using loops and creating clones.

Six copies of the Scratch cat against an aqua blue background form a hexagonal synchronised swimming formation

There’s also an Archery project, where you must overcome an archer’s shaky arm to shoot arrows as close to the bullseye as you can, and Sprint!, which uses a 3D perspective to make the player feel as though they’re running towards a finish line. This project can even be coded to work with a homemade running mat! These two projects are only available to registered Code Clubs, and require an ID and PIN to access.

Creating new Olympics projects is just one of the ways in which the Raspberry Pi Foundation and Code Club are working together to create awesome new resources, and there’s much more to come!

ALPHA vs. The Pro – Judgement Day

Firstly, let’s set the mood. I need you to watch this video.

Go on. Stop what you’re doing and press play. I can wait…

Dang Dog Blog – Timeline | Facebook

Little Top Gun and The Force Awakens Mash up. https://youtu.be/k56JAcurEQY

Done? How good was that, right? RIGHT?! Mmmhmm, I knew you’d like it.

Now, onto ALPHA…

I’ll set the scene.

Imagine it’s the mid-eighties. Your name is Dr Myles Dyson and you’ve just invented the neural-net processor. You see your invention as a massive success, a gift to humanity, a major stepping stone across the treacherous waters toward world peace.

… and then Sarah Connor shoots you.

Wait.

That’s Cyberdyne. This is Psibernetix. My bad. I’ll start again.

University of Cincinnati doctoral graduate Nick Ernest may not have built the neural-net processor (thankfully), but he’s definitely created something on that level. Ernest and his team at Psibernetix have created ALPHA, an AI set to be the ultimate wingman of the sky(net)… which runs on a Raspberry Pi.

Exciting, yes? Let me explain…

ALPHA is an artificial intelligence with the capability to out-manoeuvre even the most seasoned fighter pilot pro, and to prove this, ALPHA was introduced to retired U.S. Air Force pilot Col. Gene Lee in a head-to-head dogfight simulation.

When pitted against Col. Gene Lee, who now works as an instructor and Air Battle Manager for the U.S. Air Force, ALPHA repeatedly shot down the pro, never allowing Lee to get a single shot in.

“I was surprised at how aware and reactive it was. It seemed to be aware of my intentions, and reacting instantly to my changes in flight and missile deployment. It knew how to defeat the shot I was taking. It moved instantly between defensive and offensive actions as needed.”

Before ALPHA, pilots training with simulated missions against AIs would often be able to ‘trick’ the system, understanding the limitations of the technology involved to win over their virtual opponents. However, with ALPHA this was simply not the case, instead leaving Lee exhausted and thoroughly defeated by the simulations.

“I go home feeling washed out. I’m tired, drained, and mentally exhausted. This may be artificial intelligence, but it represents a real challenge.”

Prior to their work alongside Col. Gene Lee, ALPHA was set up against the current AI resources used for training manned and unmanned teams as part of the Air Force research programme. Much like its sessions with Lee, ALPHA outperformed the existing programmes, repeatedly beating the AIs in various situations.

ALPHA vs. Gene Lee

Nick Ernest, David Carroll, and Gene Lee vs. ALPHA

In the long term, ALPHA looks set to continue to advance in the field with additional development options, such as aerodynamic and sensor models, in the works. The aim is for ALPHA to work as an AI wingman for existing pilots. With current pilots hitting speeds of 1,500 miles per hour at altitudes thousands of feet in the air, ALPHA can provide response times that beat their human counterparts by miles; this would allow for Unmanned Combat Aerial Vehicles (UCAVs) to defend pilots against hostile attack in the skies, while learning from enemy action.

This ability to run ALPHA on such a low-budget PC makes the possibility of using the AI in the field all that more achievable. As confirmed by Ernest himself (we emailed him to check), the AI and its algorithms can react to the simulated flight’s events, and eventually real-life situations, with ease, using the processing power of a $35 computer. 

And that, ladies and gentlemen, is incredible.

Nine-year-old inventor’s award-winning asthma monitor

We keep a very close eye on the annual Tech4Good competition, and especially the children who are nominated for their BT Young Pioneer award; there are some fiercely smart kids there doing some hugely impressive work. This year’s was a very close field (I would not like to have been judging – there were some extraordinary projects presented).

Tech4Good award winners 2016

Tech4Good award winners 2016

Arnav Sharma, nine years old, was the Winner of Winners as well as the winner of the People’s Award with this asthma monitor, which runs on Raspberry Pi. Arnav started by learning about the causes and effects of asthma, and thought about ways to help patients. He discovered that asthma is hard to diagnose, but can be fatal if left undetected. This leads to many children being over-diagnosed and over-medicated; inhalers are often given as treatment to reduce the symptoms of asthma, but come with side-effects like reduced growth and immunity. Arnav discovered that the best way to manage asthma is to prevent attacks by understanding what triggers asthma attacks and following a treatment plan.

Asthma Pi

AsthmaPi

Arnav’s AsthmaPi uses a Raspberry Pi, a Sense HAT, an MQ-135 Gas Sensor, a Sharp Optical Dust Sensor and an Arduino Uno.The sensors on the SenseHAT are used to measure temperature and humidity, while the MQ gas sensor detects nitrogen compounds, carbon dioxide, cigarette smoke, smog, ammonia and alcohol, all known asthma triggers. The dust sensor measures the size of dust particles and their density. The AsthmaPi is programmed in Python and C++, and triggers email and SMS text message alerts to remind the owner take medication and to go for review visits.

Here’s Arnav’s very impressive project video, which will walk you through what he’s put together, and how it all works.

Raspberry Pi Watch, Dr Who Style

Back in the mists of time, when Apple released the Apple Watch, there was gentle buzz in the Raspberry Pi community about the Raspberry Pi’s potential in DIY smartwatch projects. That gentle buzzing subsided, like the buzzing of a wasp succumbing to flypaper, pretty quickly once people realised that a regular Raspberry Pi, while very tiny when compared to your desktop computer, is actually a bit massive when compared to your standard watch.

Here’s Alex Eames’ effort, which he made in 2014 as a response to the Apple Watch. It is less of a wristwatch and more of a forearm watch. Terrific proof of concept, but zero points for usability. (Alex has a great and very informative video to go with it: check it out.)

alex eames forearm watch

The Alex Eames forearm watch

How times change. Since 2014, we’ve released the Raspberry Pi Zero, and peripherals companies have been making teenier and teenier displays. Smaller watch devices are now buildable at home. And they’re starting to look pretty good. Here’s our favourite so far.

Jeremy Lee, an amateur astronomer, has been thinking about ways to automate running back and forth between telescope and Linux device.

Why do I need such a thing? Well, personally, I’ve found that doing digital astronomy is a pain in the ass if you have to keep running between the telescope and PC. Especially if one is inside the house. Or you’re in the field, literally.

He found his ideas and build started to snowball, and ended up with this: the Manipulator Zero. It’s tiny, it puts the raw power of the Linux desktop on your wrist, watch-style, it’s got gyroscopes for tilt-control – and best of all, it’s housed in a Dr Who Vortex Manipulator (Captain Jack’s wristwatch thingy, for those of us not paying quite enough attention).

The “gyromouse” driver Jeremy has put together means that most applications which don’t require a lot of typing or shift-clicking can be used easily by tilting the wrist (and he can type with the Florence on-screen keyboard – slowly). Here’s a very neat demo of the gyromouse in action:

Gyromouse Demo – Smallest GUI in the world?

http://unorthodox-engineers.blogspot.com.au/2016/06/pi-manipulator-build-part-1.html The Raspberry Pi Zero is tiny and powerful, but how do you operate a machine with no mouse or keyboard, and too small to have a sensible touchscreen? (4cm diagonal) First, you need the heart of a quadcopter – an MPU6040 Inertial Management Unit.

Jeremy says:

What makes the device actually useful is that it’s a full Linux machine, with a WiFi connection. That makes any nearby PC that can run SSH or VNC into a handy keyboard, mouse and ‘big’ screen. Or even a remote PC – once the manipulator is on the network, it doesn’t matter where it is, or you are. It acts very much like a ‘cloud server’ which just happens to be located on your wrist.

We, you’ll be unsurprised to learn, love it. Jeremy has written the first of two blog posts about the build, and also made this video, which we recommend you spend a while cooing at in awe. Thanks Jeremy!

Manipulator Zero – Linux Smartwatch

So rather than do a detailed build video for a device that no-one else should even attempt to make (in this exact form, it was basically microsurgery) I decided to put it to music, and try to convey the overall process. You can operate the pause button as you wish.
