The Official Raspberry Pi Projects Book

The Official Raspberry Pi Projects BookI’ve been writing for The MagPi, the official magazine of the Raspberry Pi Foundation, since its major relaunch under the editorial leadership of Russell Barnes. That’s long enough to have built up a reasonable amount of content – and it’s that content you’ll find the The Official Raspberry Pi Projects Book, published today under a Creative Commons licence.

Inside the 200 page book, which is available in print and as a DRM-free PDF download, you’ll find several pieces of my work. The first is entitled ‘Crowdfundings Greatest Hits,” an eight-page investigation of some of the biggest Pi-related crowd-funded projects around – and some of its biggest failures, too. This was a great piece to work on, involving plenty of research and interviews, and was the first to break the news that Azorean was relying on additional external investment to fulfil rewards in its Ziphius campaign – rewards which have still not been fulfilled, more than a year after its original launch date.

You’ll also find reprints of several of my reviews: there’s the Pimoroni Display-o-Tron 3000 add-on, the Weaved IoT remote access system, the 4Tronix Agobo low-cost robot chassis, Velleman’s 3D Printing Pen, and the excellent Swanky Paint from local coding outfit WetGenes. Naturally, each is accompanied by photography which is also published under a Creative Commons licence – and is, as always, available for reuse from my Flickr page.

This marks the first book to which I have contributed which is published under a Creative Commons licence, but it certainly won’t be the last. Allowing for free non-commercial reuse and encouraging sharing and copying, it’s an approach at the complete opposite end of the spectrum to that taken by most publishers – and one of which I heartily approve.

You can download The Official Raspberry Pi Projects Book for free from the official website, while print copies are available from the swag store or the usual high-street outlets.

Custom PC, Issue 145

Custom PC Issue 145In the pages of this month’s Custom PC magazine you’ll find my regular Hobby Tech column split into three segments: a two-page review of the Velleman 3D Printing Pen, a further two pages of coverage from the Liverpool MakeFest, and a final page reviewing the excellent Petduino from Circuitbeard.

First, the Velleman pen, kindly provided by CPC. Considering that I write a column about – among other topics – maker culture, it’s a real surprise I’ve never really delved into 3D printing before. It’s a topic that interest me, but one which is difficult to address easily: printers are bulky, expensive, and even when review samples are available they typically need hours of assembly and fine-tuning which can be difficult to fit into a freelancer’s budget.

The Velleman 3D Printing Pen, on the other hand, requires close to zero set-up. Connect the mains adapter, insert some of the bundled PLA filament, and hold down the motorised feed button, and it starts chucking soft filament out of the nozzle like a good ‘un. It’s a simple design, based on glue guns and ‘inspired’ by the pre-existing 3Doodler, but it lacks the fine control of a true 3D printer: the box shows someone ‘drawing’ the Eiffel Tower, but I call shenanigans on that one.

The event coverage comes courtesy of client oomlout, on whose behalf I attended the first Liverpool MakeFest. It was, as these events often are, a stunning success and great fun, despite a hiccough where my cheap Jessops speed-flash died a few minutes into the day – an issue I was thankfully quickly able to resolve by running to a nearby photography shop and picking up a second-hand Nikon replacement, thusly also blowing any hope of seeing a profit.

Regardless, there were several personal highlights from the day including a great chat with the event founders and seeing friends including Ben Grey of MeArm fame and Adrian McEwan of DoES Liverpool with his ever-popular Nerf shooting range. I was also pleased to learn that the response of the public was good enough that the Liverpool Central Library is keen to work with organisers to run the MakeFest as an annual event.

Finally, the review. I met up with Circuitbeard – more properly known as Matt Brailsford, and yes his beard is impressive in the hairy flesh – at the recent Halifax Mini Maker Faire, where he was kind enough to provide me with a prototype of his Petduino design. Based on the Arduino platform, the Petduino is part development board and part virtual pet. Designed to get kids – and the young-at-heart – interested in software and hardware development, the Petduino comes with a range of open-source ‘personality’ Arduino sketches which can be installed and hacked about to change its behaviour. It’s a great tool for teaching, and with sales of the initial batch off to a flying start one I predict will be very successful – and I can’t wait to see the promised add-on kits Matt has planned.

All this, plus the usual raft of interesting things written by people who aren’t me, can be yours with a trip to your local newsagent, supermarket, or digitally via Zinio and similar services now.

The MagPi, Issue 36

The MagPi Issue 36This month’s The MagPi, the official Raspberry Pi magazine, is rather special: it’s the first print issue since the community-created publication was taken under the wing of the Raspberry Pi Foundation. While previous issues were available in limited-edition print runs created through crowd-funding efforts, from now on the magazine will be found in major high-street shops as standard – starting with WH Smith. This doesn’t mean the free digital download is going away, though: all content is still Creative Commons licensed, and the PDF download will be available free of charge at the same time as the print issue hits shelves.

Publication changes aside, there are two pieces of note in this month’s issue: a review of Wetgene’s Swanky Paint, and another of the Velleman 3D Printing Pen.

Going for the hardware first, local electronics giant CPC was kind enough to send over a box of goodies including the printing pen and some wearable kits – about which you’ll read more in future issues – when they found out I was running low on review hardware. Created by Velleman, a company better known for its test equipment, the 3D Printing Pen is a near-direct copy of the 3Doodler: the extrusion system of a PLA-based 3D printer stripped out of its three-directional housing and placed inside a pen-like grip.

The idea, the instructions explain, is that you can ‘draw’ three-dimensional objects freehand – taking away the complexity and expense of a traditional 3D printer. The remaining technology is simple, and nothing particularly new: you can think of the pen as a glue-gun using plastic in place of glue. The box shows someone drawing a scale model of the Eiffel Tower freehand, but I found it a major struggle to even get my simple cubes and pyramids looking recognisable.

I had a lot more luck with Swanky Paint, created by local coding house Wetgenes. I had previously interviewed the two programmers behind the software back in Custom PC Issue 141, but this time I took their most famous creation in-hand and gave it a thorough testing: Swanky Paint. Available in cross-platform browser-based flavours as well as native versions for traditional PCs, smartphones, tablets, and the Raspberry Pi, Swanky Paint is inspired by EA’s classic Deluxe Paint – the go-to art package for an entire generation of game artists – and shares UI and UX similarities, down to the keyboard shortcuts on offer.

Where Deluxe Paint had its pixels on show due to the low resolution of computing equipment at the time, though, Swanky Paint revels in it. Designed for retro ‘pixel-art’ projects, the software makes everything as easy as possible and includes a surprising level of polish for an early alpha release – including various effects designed to emulate the smoothing glow of a traditional CRT display.

If you want to find out my conclusions on both products, as well as read a bunch of great stuff by people who aren’t me, you can pick up a print copy of The MagPi Issue 36 in your local WH Smith, or download the free PDF from the official website.
