New Raspberry Pi Compute Board Available in Australia

Hold on to your hats ladies and gentlemen because I've got something really exciting for you! The Raspberry Pi Foundation announced the newest iteration of their hugely popular Raspberry Pi Compute module. 'What on earth is a Compute module?' I hear some of you ask? Well, the Raspberry Pi Compute debuted in 2014 and was designed to provide all of the awesomeness that is Raspberry Pi in a smaller, more compact package suited towards industrial and commercial applications.

It featured the same SoC, processor and specs, but got rid of the physical ports (USB, HDMI, Composite, microUSB etc...) and provided access to all of those peripherals and the GPIO via the output pins of it's SODIMM package. Now that was all well and good, but compared to the current Pi 3 specs, the older Compute module was languishing a little, so they've updated it!

The Raspberry Pi Compute 3 module packs the same horsepower that the current Pi 3 delivers with twice the RAM of the original module, roughly 10x the processing power, plus lots of extra goodies. The biggest change they've made with this release though is the provision of two different options for the module dubbed the Compute Module 3 and Compute Module 3 Lite. They both have exactly the same specifications, however, the Compute Module 3 sports 4GB of eMMC flash storage. The Lite version lacks this, however, it breaks out the pins required for the eMMC or microSD to the SODIMM pins.

The Raspberry Pi Compute Module Development Kit incldues both the normal and lite variants of the compute, along with all the other bits and pieces you need to get started.

According to the Raspberry Pi Foundation, you can pick up the Compute Module 3 and Compute Module 3 Lite for $30 and $25 respectively, however that's in US Dollars, so expect to pay a bit more in Australia, but it's still a nice saving over the regular Pi 3 if the Compute better suits your application. NEC have reportedly used the Compute Module 3 in the new range of HD TV's which is a huge breakthrough to seeing DIY technology come together with industrial applications. Super exciting stuff!

For more info, check out the official Raspberry Pi Foundation post revealing the CM3 and CM3L.

Build Your Own Acoustic Tractor Beam

Let's be real if you've ever watched Star Wars, you've probably thought of all the possibilities that would open up to you if you had your own tractor beam. The TV remote would never be out of reach, the fridge would be just a button away, and the neighbour's cat could always be put up a tree in case of an 'emergency'. Well, now your dreams can come true. Well, partially at least.

Asier Marzo is an inventor and fellow maker, and created a small but effective 'tractor beam' using acoustic energy. He uses an array of transducers to suspend small objects in the air above the array (remember that sound waves are just pressure waves). The whole thing is controlled using a small Arduino board, and features a 3D printed dome pattern to mount the transducers.

The robot responds entirely in GIFs

Robots are pretty awesome, and GIFs are hilarious. What happens when you combine the two with a little engineering style? You get yourself a Peeqo robot. 

Peeqo was created as a personal assistant style robot that you can call upon to provide with a GIF for any situation. To hear your words and turn them into tasty GIFs, Peeqo uses Google Cloud Speech. The GIFs are displayed on the 800x480 Pixel display that is his "Eyes". 

Peeqo can move his head around like a human too, shaking and nodding when he hears someone speak directly to him. 

Check Peeqo in action here:

The movement is controlled by some servo motors and an Arduino Mini, with another Mini being used for controlling the NeoPixel ring on Peeqo's crown. There are 4 microphones that allow you to speak to him from anywhere in the room too! The Arduinos use I2C to communicate to the Raspberry Pi that's literally mounted where Peeqo's brain goes aswell. There is an awesome write-up available for this project here, including all the code and STLs you need to make your own.

Automate your caffiene regimen with this quick Raspberry Pi Project

Caffeine is undoubtedly one of the most important drugs in the western world. And Tea boasts a great amount of caffiene, not to mention the added health benefits. Plop a tea bag in a cup, add some boiling water and 80-90 seconds later you have a perfect cuppa! Obviously, that simplicity is wasted on one maker out there and he decided to skip the wait time and automate the Tea brewing process.

The ingenious use of an old CD Drive alongside a Raspberry Pi can remove your tea bag for you, bypassing any chance of an over brewed cup. The code is very simple and all you need is a CD drive, a paddle-pop stick and a bag of your favorite brew. Check out the maker's GitHub here for the code and instructions you need.

Orchestral Marble Machine

Here's something a bit different to brighten your day. It's an acoustic instrument that's powered by nothing more than a crank handle and some levers. That's right, there is nothing electronic about it. Strange, blogging about this on a website which has 'electronics' in its name, but it is simply too awesome not to share. This incredible projects, posted by Youtuber Wintergatan is a perfect example of engineering and creativity coming together to make something awesome, an instrument that makes sounds using marbles and gravity.

What's mind blowing is that it's made mostly out of wood! Now think of the possibilities of something like this controlled by an Arduino. You could write symphonies with the thing.

Dr Who DIY Arduino Synthesiser

Well Dr Who fans, this one is for you. Youtuber Martin Orman posted a video just before the new year of his very own Dalek synth. He picked up the Dalek toy at a car boot sale, so there's definitely wear and tear, but then he fitted it with an Arduino board complete with audio outputs and controls to bring his software synth to life! 

The best thing about seeing projects like this is the recyclable mentality of it. An old toy which might otherwise get thrown away into a landfill. That and it's a totally fun project for kids and adults alike, create your own synthesiser and learn a bit more about electronic music!

Arduino IDE Unified at Last

If you've kept up with the drama that has followed the Arduino brand over the last couple of years, then you'll know all about the Arduino.cc and Arduino.org split that occurred, and the pain that it caused consumers in differentiating between the two brands. If not, check out our other blogs to get caught up, however, today we have good news. Arduino has released a new build of it's IDE (Integrated Development Environment) with IDE 1.8.

The major issue was that Arduino.cc and Arduino.org both released different boards with different chips on them that required different core modules and would often only work with the corresponding IDE, despite being under the 'Arduino' umbrella. All of these headaches should be a thing of the past now with IDE 1.8 supporting cores for both the new AVR based boards and existing SAMD ARM Cortex based boards.

There aren't many changes or features added in this release, but a lot of work has gone into ensuring that this release is a successful step towards bridging the Arduino/Genuino divide that has plagued DIY'ers over the last couple of years.

For a more detailed collection of what 1.8 brings to the table, take a look at the release notes here.

Turn Your Raspberry Pi Into a Smart Projector

With all my adventuring in Raspberry Pi this year, I've grown to appreciate the little green board and what it can do. I've got a long list of projects in mind for it and seeing other awesome Raspberry Pi projects just fuels that fire. So when I stumbled upon this Raspberry Pi 'smart projector', it sent my mind into overdrive, and just had to write about it.

The Raspberry Pi, of course, has multiple ways to output video, and this makes it perfect for all kinds of modern displays including HDMI screens and LCDs. Seeing the way that 'Novaspirit' uses the Pi Zero's small form factor to pack it into a projector is really cool, and the functionality to turn it into a mobile gaming setup with RetroPie is just too good.

Bear in mind, that if you could find a projector that could fit a Pi 3, you wouldn't need to worry about the USB hub or other soldering, you could simply use the native HDMI and built-in Wi-Fi and Bluetooth to create the ultimate portable rig.

The Coolest Floating DIY Lab!

So most of us DIY'ers have an assortment of tools, projects, and components lying around which we consolidate into a DIY lab. Some labs have all kinds of wacky and wonderful machines which get used less often than we'd care to admit, and others consist of the bare essentials required to build fantastic things. 

Not content to have an 'average lab', a make by the name of Steve Roberts has created his dream lab, wait for it, on a boat! It's a high-tech, floating lab that he can live on. That's the dream right? But despite possible disconnect that floating in the middle of the ocean may bring, the truth is far from an isolated maker. 


His floating lab packs a punch with a gigabit internet connection, 3D printer, CNC mill, oscilloscopes and power supplies aplenty, plus plans to put a battery on board to compliment the current engine. A hybrid boat you might say.

He gave IEEE Spectrum a full tour, so for more info and inspiration, check out the full article.

A new front-end for your RetroPie

The typical front end environment that you get stock standard on RetroPie is called Emulation Station. It visually manages your games and emulators using an application similar to that of KODI media center. 

Emulation Station is fantastic too; it's got styleable interfaces for each emulator, you can have overlays on screens, controller config management is done extremely well. 

Well user Floob over on the RetroPi forums decided he wanted to go a step further and make his owm front end to rule them all. He came up with Attract Mode and boy does it attract:

If you're sold on the idea of the Attract Mode visual setup for your retropie, find out more here.

Liftware Robotic Spoon

If all you read today is this blog post, then hopefully it was time well spent. May I introduce to you one of the best projects I've seen all year. It's called Liftware and was created to solve a problem that few knew existed.

Whilst there have been plenty of fantastic innovations for those who struggle with physical disabilities, eating, a basic function of human life can still be problematic due to the loss of fine motor control. But no longer.

Liftware is a spoon unlike any other. It consists of a spoon attachment which connects to the handle via a flexible coupling which contains motors. Inside the handle is a combination of gyroscopic and accelerometer sensors which detect the orientation of the handle. The motors then adjust the position of the spoon to ensure it remains level and flat regardless of how the handle is held and negates tremors and accidental movement.

This is a fantastic implementation of electronics and robotics to solve a problem that causes difficulty in the lives of others. The best part about it is that the technology behind it isn't complicated, and could easy be created using components from our store, or you that you might already have lying around.

Hopefully, this inspires the inventor inside of you to create projects that are both fun, and help people with everyday problems!

Exciting New Features On Teensy 3.5 and 3.6!

So in my exploration of the new Teensy 3.5 and 3.6 boards, one of the features that stood out to me most of all was the addition of a second USB port. This is big news because traditionally with Arduino compatible boards, there is a single USB port of the chip, sometimes not even that (UART-USB conversion). This isn't a physical USB plug, but the port peripherals on the chip which are designed to be configured and connect to a physical USB socket. Now, why does this excite me? The reason is simple.

Teensy 3.6 board

The combination of the 180MHz clock speed and raw power of the Teensy 3.6 makes it the perfect device to create a powerful, polyphonic synthesiser. Yes, I know that this is nothing new and people have done this with previous gen Teensy boards, but normally the only control method is knobs and dials. But the new 3.6 with the 2nd USB port means that it could be configured to work in host mode to connect up external USB MIDI devices such as keyboards and controllers. Sure keyboards with DIN-5 MIDI jacks can be used easily via a UART port, but many keyboards now are exclusively USB.

Paul Stoffregen hasn't created libraries to support this extra USB port yet so it could be months off, but with the maker community being the curious beast that it is, hopefully, next year will be the start of many fancy projects!

Particle Cloud, Coming to a Raspberry Pi Near You!

So if you don't know what Particle.io is, I highly recommend that you go and check it out now. It's a powerful, cloud-based environment for programming their exceptionally powerful microcontroller boards in any easy to use fashion, that will be familiar to any Arduino user. But the beauty of Particle.io is that not only can you program firmware and send firmware updates OTA, but you can monitor device logs, webhook integrations, and much more. Now this is all well and good, but it's tied to their Photon (Wi-Fi) and Electron (3G) boards. But no more! earlier in November, Particle announced their intention to bring their fantastic cloud platform capabilities to the world's most popular microcomputer; Raspberry Pi. By downloading the Particle agent to your Raspberry Pi, you can terminal level CLI interaction, as well as all of the cloud-side functionality, in the easy to use Wiring abstraction for C++.

Raspberry Pi + Particle

While Particle has only released Beta testing to small numbers of customers so far, an open launch isn't too far away. And you can bet when it does go public, we'll have tutorials and projects ready to go!

Awesome Raspberry Pi LED Christmas Tree

So, most christmas decorations are kind of lame. Let's be honest here. It's usually just a random assortment of mis-matched baubles and fairy lights with less symmetry than the leaning tower of pisa. Not to mention the christmas tree up against the wall with tinsel only draped accross the visable side to save time. Yes it's true, there has been little innovation in the niche that is Christmas decorations. Until now.

Pi Hut LED Christmas tree

The good people over at The Pi Hut in the UK have released a 3D Christmas Tree circuit board kit, and it looks awesome. You simply solder some LEDs onto the PCb cut-outs, solder the resistors and headers on, and it plugs straight into the header pins on your Raspberry Pi. Such a simple, yet glorious mesh of creativity and fun. While we won't be able to stock them in time for Christmas, it'll be good to see more kits like these which find creative ways to engage kids and adults alike with simple electronic projects.

You can download their sample code to turn the LEDs on in various ways, or write your own!
